Since the sartans crisis in 2018, the detection of nitrosamines has highlighted systemic gaps in identifying contamination pathways across pharmaceutical supply chains. As impurities belonging to the “cohort of concern” following ICH M7 (R2) , nitrosamines present exceptionally high carcinogenic potency. Their mechanism of action relies on metabolic activation leading to the formation of adducts. If these lesions escape cellular repair systems, they can induce irreversible genetic mutations and carcinogenesis. With a TD50 typically below 1.5 mg/kg/day, this extreme toxicity prevents the application of the standard Threshold of Toxicological Concern (TTC) of 1,500 ng/day defined in ICH M7(R2). Acceptable Intake (AI) and carcinogenic potency assessment Patient safety is ensured through the establishment of an Acceptable Intake (AI), calculated for a theoretical excess cancer risk of 1 in 100,000 over a 70-year exposure. For compounds with sufficient data, the AI is derived through linear extrapolation from the most conservative TD50 values obtained in the most sensitive species. For NDSRIs (nitrosamines related to the active substance) lacking in vivo data, the CPCA (Carcinogenic Potency Categorisation Approach) recommended by the EMA is applied. This method classifies nitrosamines into five potency categories based on structural characteristics influencing metabolic activation. Alternatively, a negative Enhanced Ames Test (EAT) can justify the application of a limit of 1,500 ng/day. Sources and formation of nitrosamines   Control of these impurities requires a rigorous strategy. Nitrosamine formation generally results from the combination of amines with nitrosating agents under acidic conditions. Identified sources include: Contaminated or degraded solvents Nitrites present in excipients Risk management strategy Risk management follows three main steps: Proactive assessment Confirmatory testing Implementation of CAPA According to ICH M7, omission of specification may be considered if levels remain consistently ≤10% of the AI. Batch-by-batch control is required when levels are between 30% and 100% of the AI. When multiple nitrosamines are present, summation strategies must ensure that cumulative risk never exceeds the 1:100,000 threshold. Mitigation options Reformulation can be an effective mitigation strategy. The addition of nitrite scavengers or pH adjustment can slow nitrosation reactions. In some cases, these modifications may benefit from simplified procedures and avoid new bioequivalence studies.

Since 12 January 2026 , the European Union has reached a major milestone in the protection of public health and water resources. The transition period provided for under Directive (EU) 2020/2184 (recast Drinking Water Directive) has now ended. From now on, the systematic and harmonised monitoring of per- and polyfluoroalkyl substances (PFAS) is a legal obligation for all Member States.    1. A dual-threshold regulatory framework    The Directive now requires compliance with two distinct limit values, reflecting complementary monitoring objectives:  → “Sum of PFAS” (0.10 μg/L)   This parameter specifically targets 20 individual substances considered of concern. Listed in Annex III of the Directive, they include 10 perfluoroalkyl carboxylic acids (PFCAs) and 10 perfluoroalkyl sulfonic acids (PFSAs), with carbon chain lengths ranging from 4 to 13 atoms. The limit value is set at 100 ng/L for the sum of these compounds.  → “PFAS Total” (0.50 μg/L)   This parameter takes a much broader approach by covering all per- and polyfluoroalkyl substances . The limit value is set at 500 ng/L . The objective is to capture the total organofluorine load, including thousands of molecules not covered by the “Sum of PFAS”.  In accordance with Article 13(7) of the Directive, and following consultations with Member States, technical guidelines (C/2024/4910) have been published to define the analytical methods applicable to these two parameters.    2. Analytical control: requirements for the “Sum of PFAS”    The assessment of compounds under the “Sum of PFAS” relies on liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). The EN 17892:2024 standard, used as the reference analytical method, recommends two methodological approaches:  Part A (Direct injection): a rapid method in which unfiltered drinking water samples are injected directly into the LC-MS system.  Part B (SPE enrichment): this method involves solid-phase extraction (SPE) to concentrate the sample, providing higher sensitivity and lower quantification limits.    3. The technical challenge of “PFAS Total”    The comprehensive measurement of PFAS represents a major scientific challenge, as no single method can quantify all compounds in this chemically diverse group. Three approximation methods are currently validated by the Commission:  TOP assay (Total Oxidizable Precursors)    This method uses chemical oxidation to convert PFAS precursors into measurable perfluorocarboxylic acids. However, it may lead to underestimation, as some compounds (notably perfluorinated ethers) are not fully oxidised.  EOF-CIC (Extractable Organic Fluorine)    This method measures extractable organic fluorine via combustion and ion chromatography. The result, expressed in ng/L of fluorine, is converted into PFOA-equivalent using a conversion factor of 1.45 (thus, 345 ng/L F corresponds to 500 ng/L PFAS Total).  LC-HRMS (High-resolution mass spectrometry)    This non-targeted approach enables the detection of a much broader range of compounds. However, it remains semi-quantitative and requires a high level of expertise to interpret signals and minimise false positives.    4. The critical case of trifluoroacetic acid (TFA)     TFA is an ultra-short-chain PFAS (2 carbon atoms), characterised by high mobility, persistence, and strong hydrophilicity. It enters the water cycle through the degradation of pesticides, refrigerants, or industrial discharges. In many Member States, concentrations measured in untreated water frequently exceed the 0.50 μg/L threshold, thereby surpassing the parametric value for “PFAS Total”.  To address this issue, the Commission requires a four-step reporting protocol:  Measure [PFAS Total] using an approximation method.  Measure [TFA] specifically using a targeted analytical method compliant with the Directive.  Report three values: [PFAS Total] , [TFA] , and the difference [PFAS Total] – [TFA] .  If the result is negative, the measurement is considered inconclusive.    5. Performance criteria  To ensure measurement reliability, the Directive establishes several analytical requirements at the point of compliance:  Limits of quantification (LOQ)    The overall LOQ must be ≤ 30% of the parametric value , i.e. 30 ng/L for Sum of PFAS. However, the Commission recommends an individual LOQ of ≤ 1.5 ng/L for each of the 20 substances. For “PFAS Total”, the LOQ must be ≤ 150 ng/L.  For the most toxic compounds identified by EFSA (PFHxS, PFOA, PFOS, PFNA), even lower target limits are recommended.  Measurement uncertainty    The Directive sets a maximum expanded uncertainty of 50% at the parametric value level. In practice, European laboratories generally achieve better performance, with uncertainties ranging from 18% to 39% depending on the method used.  Validation of measurements    At ultra-trace levels (ng/L), environmental and laboratory conditions become limiting factors. Member States must ensure that analytical methods used for monitoring and compliance demonstration are validated in accordance with EN ISO/IEC 17025 or an equivalent internationally recognised standard.  Current limitations    Unlike the “Sum of PFAS”, methods for measuring “PFAS Total” are not yet fully harmonised at the European level. Available data on measurement uncertainty and LOQ remain limited, making it difficult to fully assess compliance with regulatory performance criteria for this global parameter.    6. Immediate actions in case of exceedance    The entry into force of these requirements means that any non-compliance must trigger immediate corrective actions to protect public health.  Water managers, under the supervision of national authorities, must:  Inform the public transparently about risks and precautionary measures.  Shut down wells or abstraction points where PFAS levels are excessive.  Implement specific treatment processes (activated carbon, ion exchange resins, or reverse osmosis) to remove contaminants.  Restrict water use if necessary until compliance is restored.    Conclusion  The implementation of these provisions is part of the “Zero Pollution” Action Plan . The new reporting framework now requires systematic transmission of data on exceedances and incidents to the Commission.  Beyond tap-level compliance, a comprehensive approach is required, including risk assessment from the abstraction area onwards. Anticipating pollution sources, combined with mastering complex analytical protocols (particularly for PFAS Total and TFA), is essential for ensuring sustainable and secure water resource management.    Authors: Floriane DEMAILLY & Loris MISTRULLI References:   Directive (EU) 2020/2184: Directive (EU) 2020/2184 of the European Parliament and of the Council of 16 December 2020 on the quality of water intended for human consumption (recast), OJ L 435 , 23.12.2020, pp. 1–62 .

The recent amendment to the European Cosmetic Regulation significantly expands the list of fragrance allergens that must be declared on the INCI label (Regulation (EU) No 2023/1545 updating certain entries of Annex III of the EU Cosmetic Regulation).  In the original version of Regulation (EC) No 1223/2009, 26 allergens were subject to mandatory labelling. Two of them ,Lyral and Lilial, have since been prohibited. The new regulation adds 57 additional substances , bringing the total number of l abelled allergens to 81 . These include individual molecules as well as botanical extracts and essential oils that may induce skin allergy. Products already on the market containing these substances must be reviewed more closely, both to ensure correct labelling and to clarify potential risks.  The intrinsic risk of skin sensitisation of a product does not automatically change. However, if a substance was not previously identified, it may now need to be considered, particularly if the product claims to be “hypoallergenic” or suitable for “sensitive skin.”  Among the newly concerned substances are widely used cosmetic ingredients such as:  Vanillin   Benzaldehyde   Lavandin oil and extracts (Lavandula Hybrida Oil)   Peppermint oil (Mentha Piperita Oil)   Labelling is required when concentrations exceed:  0.001% in leave-on products   0.01% in rinse-off products   The regulatory deadlines are clearly defined:  Products placed on the market must comply by July 31, 2026   Products already on the market must comply by July 31, 2028   This regulatory development requires companies to conduct a systematic review of fragrance compositions, supplier data, and safety documentation.  However, labelling is only one part of the regulatory obligation.  Beyond Labelling: Annex I Requires a Complete Safety Assessment   Article 10 and Annex I: Mandatory Update of the Cosmetic Product Safety Report (CPSR) Article 10 of Regulation (EC) No 1223/2009 and Annex I require a complete safety assessment based on documented toxicological profiles and the calculation of the Margin of Safety (MOS) for each ingredient. Article 10(1)(c) specifies that the Safety Report (CPSR) must be updated whenever new relevant information becomes available.  A compliant cosmetic safety assessment requires :  The use of documented toxicological profiles   Evaluation of local effects (sensitisation, irritation, phototoxicity) and systemic effects, including identification of relevant concerns (critical warnings)  Calculation of the Systemic Exposure Dose (SED)   Determination of the Margin of Safety (MOS)   Integration of conclusions into the Cosmetic Product Safety Report (CPSR)  Margin of Safety (MOS): The Central Indicator in Cosmetic Risk Assessment The Margin of Safety (MOS) is the core regulatory indicator used to demonstrate ingredient safety within the CPSR framework.  It quantitatively expresses the relationship between hazard (NOAEL or relevant point of departure POD) and actual consumer exposure.  A product may comply with labelling thresholds while still requiring an in-depth evaluation. It is important to note that the 2012 SCCS opinion focused on skin sensitisation and did not address other potential toxicological endpoints.  Regulatory compliance therefore relies on a structured demonstration of the hazard × exposure assessment , not solely on verification of labelling thresholds.  Allergens requiring labeling (underscored) are identified based on their final concentration and the type of product. A margin of safety or margin of exposure is calculated each time it is possible.   Operational Impact: Recalculation of Margins of Safety and Update of the PIF   The transition from 24 to 81 labelled allergens significantly increases operational complexity:  Verification of fragrance compositions and botanical extracts  Recalculation of cumulative concentrations  Verification of the need to add allergens to the ingredient list  Confirmation of exposure scenarios  Reassessment of risks and recalculation of Margins of Safety  Update of the safety assessment through the CPSR and the Product Information File (PIF)   Any modification in concentration or formulation may directly impact the SED and consequently the MOS.  Traceability and reproducibility of calculations therefore become essential.  Toxicological Database and Digital Cosmetic Risk Assessment Tool In this context, the use of a structured toxicological database combined with a digital cosmetic risk assessment tool facilitates:  Harmonised access to toxicological profiles  Consistent calculation of SED and Margin of Safety  Generation of documentation compliant with Annex I  Consideration of the SCCS assessment methods and other international frameworks.  July 2026: A Regulatory Trigger for Systematic Risk Reassessment Therefore, Regulation (EU) No 2023/1545 updates the list of labelled allergens under Annex III of the EU Cosmetic Regulation and requires an update of the regulatory dossier.  The July 2026 deadline should be considered a regulatory trigger to:  To re-examine fragrance compositions and botanical extracts with regard to labelling requirements  To verify the Margins of Safety and confirm warnings or the absence of risk, and to update the CPSR accordingly The expansion of allergen labelling aims to enhance transparency.  However, consumer protection ultimately depends on the robustness of the cosmetic risk assessment and the scientific justification of safety through the Margin of Safety .  In regulatory practice, compliance does not merely consist of updating the INCI list.  It requires a continuously documented, traceable and scientifically substantiated assessment framework. These updates are therefore not simply an administrative revision of the ingredient list; they require regulatory and scientific expertise which, at least for Part B of the CPSR — covering the safety assessment — must be validated by a qualified safety assessor (toxicologist, pharmacist, etc.), as defined in Article 10 of the EU Cosmetic Regulation.  Would you like to ensure the safe assessment of allergens in your cosmetic formulas?

In December 2025, the European Commission published a targeted legislative proposal under its Food and Feed Safety Simplification Omnibus . One of its most relevant elements for the biocides sector is a proposed amendment to Regulation (EU) No 528/2012 (the Biocidal Products Regulation, or BPR), extending certain data protection periods for active substances still undergoing review. This initiative responds to long-standing concerns raised by industry and Member State authorities and has direct implications for companies supporting active substances, data owners, alternative suppliers, and product authorisation applicants. Background: Why This Amendment Was Needed Under the BPR, approval of biocidal active substances requires extensive scientific data demonstrating safety for human health, animal health, and the environment. These data packages are costly to generate and are therefore protected for a defined period to allow data owners to recover their investment. Article 95(5) of the BPR currently provides that data protection for certain existing active substance/product-type combinations expires on 31 December 2025 , regardless of whether the regulatory review has been completed. This “hard stop” was originally intended to balance fair compensation for data owners with increased market access and competition over time. However, the EU review programme for existing biocidal active substances, initiated more than two decades ago, has experienced significant and repeated delays. Completion is now scheduled for 31 December 2030 . Key drivers of these delays include limited resources in Member State authorities, evolving technical guidance, and, critically, the introduction of new scientific criteria for identifying endocrine-disrupting properties in 2018. These criteria triggered the need for additional, often expensive, studies well after original data submissions. As a result, many companies were required to generate new data without the prospect of adequate protection if the original 2025 cut-off remained unchanged. What the Commission Is Proposing The proposal seeks to realign data protection rules with the reality of the extended review programme. In practical terms, it would: Extend data protection until 31 December 2030 for all active substance/product-type combinations that were still under review on 7 June 2018 . Apply the extension to all data within the relevant dossiers , without distinguishing between older and newly generated studies, ensuring administrative simplicity and legal clarity. Introduce a derogation allowing protection to be reinstated even if it temporarily lapsed after 1 January 2026. Allow data owners to claim compensation  from substance or product suppliers that benefited from the absence of protection during the interim period. This results in a maximum protection period of approximately 11–12 years for data generated since 2018, broadly consistent with the standard data protection framework under the BPR. Balancing Innovation and Competition Stakeholder feedback highlighted diverging perspectives. Data owners and industry associations warned that allowing protection to expire amid regulatory delays would create free-rider risks, discourage investment in new studies (including vertebrate testing), and undermine supply security. Some Member State authorities supported extending protection at least for endocrine disruptor-related data. Conversely, alternative suppliers and SME representatives cautioned that prolonged protection could limit competition, increase costs, and complicate data-sharing negotiations. The Commission’s proposal reflects a compromise: it preserves incentives for data generation and regulatory compliance while maintaining the original objective of Article 95(5) to avoid disproportionate or perpetual exclusivity. What This Means for Companies For companies active in the biocides sector, the proposal provides: Greater legal certainty  for data owners who have invested in additional studies during a delayed review process. Continued relevance of letters of access and compensation negotiations  beyond 2025. Reduced risk of immediate, uncompensated data reuse by competitors. A clearer regulatory framework pending the broader evaluation of the BPR announced for 2026–2027. Next Steps The proposal will now be examined by the European Parliament and the Council under the legislative procedure. Until it enters into force, companies should carefully assess their data protection strategies, Article 95 positioning, and contractual arrangements. We will continue to monitor legislative developments closely and provide updates on timelines, implementation details, and strategic implications for substance suppliers and product authorisation holders. If you would like to discuss how this proposal may affect your portfolio or data protection strategy, please contact our regulatory team.

ABIM 2025: a key event for European biocontrol The Annual Biocontrol Industry Meeting (ABIM) was held in Basel (Switzerland) from 20 to 22 October 2025, bringing together more than 2,000 international participants, including industrial stakeholders, scientific institutes, authorities, professional associations and consulting companies. Co-organised by the Research Institute of Organic Agriculture (FiBL) and the International Biocontrol Manufacturers Association (IBMA), ABIM has become the leading European forum dedicated to biocontrol products, biostimulants and regulatory innovations related to natural substances. The role of IBMA IBMA brings together biocontrol manufacturers and advocates for key regulatory developments to: accelerate the evaluation of alternatives to conventional products; introduce new definitions and regulatory requirements; integrate emerging technologies; strengthen the training of competent authorities. Biocontrol, biostimulants, natural substances: clarifying the concepts To support a rapidly growing sector, it is essential to clearly distinguish between regulatory categories. What is biocontrol? Biocontrol products fall under Regulation (EU) No 1107/2009 on plant protection products. They encompass several families: Microorganisms: bacteria, fungi, viruses, etc. Macro-organisms: insects, mites, nematodes used as biological control agents. Natural substances: of plant, animal or mineral origin. Semiochemicals: including pheromones and inter-species communication substances (e.g. allomones). Their mode of action is generally targeted, non-toxic and compatible with objectives to reduce the use of conventional pesticides. What are biostimulants? Biostimulants are regulated at EU level under Regulation (EU) 2019/1009 on fertilising products , or under national regulations. They do not act against pests or pathogens , but instead improve plant resilience to abiotic stresses (water stress, heat, salinity, cold, etc.) and optimise nutrient use efficiency. Two main categories exist: Microbial biostimulants Non-microbial biostimulants What are natural substances used for plant health? These are components derived from nature, including: Animal origin: sheep fat, fish oil, etc. Mineral origin: talc, sulphur, copper, clay, etc. Plant origin : algae, rapeseed, sunflower, orange, etc. New technologies , such as proteins and peptides . Products usable in organic farming: what does the regulation say? Organic production is governed by Regulation (EU) 2018/848, which defines: authorised agricultural practices; categories of natural substances that may be used, including fertilisers, biostimulants and plant protection products. A two-step authorisation process For a plant protection product to be usable in organic farming, the following steps must be completed: Approval of the active substance at EU level → Regulation (EU) No 1107/2009 → Inclusion in the list under Regulation (EU) 2021/1165 Authorisation of the product at national level → Regulation (EU) No 1107/2009 → Certification under organic labels (AB, Bio Suisse, EU Organic, etc.) Key trends observed at ABIM 2025 Regulatory acceleration Discussions highlighted: simplification of dossiers for natural and low-risk substances; modernisation of the regulatory framework; the urgent need to reduce evaluation timelines. Artificial intelligence and biocontrol Several presentations explored the role of AI in: toxicological modelling; digital risk prediction tools; optimisation of formulation strategies. Technical workshops Three major topics attracted particular interest: Semiochemicals: application methods and analytical challenges; Natural substances: classification, safety and identification; Proteins and peptides: emerging approaches in biocontrol. CEHTRA’s participation: expertise, visibility and new opportunities CEHTRA within IBMA CEHTRA acts as an associate member for natural substances and semiochemicals, actively contributing to proposals aimed at improving the regulatory framework, based on extensive field experience. CEHTRA at ABIM 2025 This year, CEHTRA was represented by Steffie Segelle, Raquel Gonzalez de la Huebra and Estelle Beltran, with: a dedicated booth; three scientific posters: endocrine disruption (ED) screening for biocontrol substances (including the Simply Predict offering); comparison between REACH and the Fertilising Products Regulation; comparison between low-risk substances and basic substances. These posters highlighted CEHTRA’s internal expertise in toxicology, regulatory assessment, natural substances, predictive AI and EU compliance. Meetings and outlook Meetings with biocontrol clients across the sector. New collaboration prospects in the areas of: biostimulants; endocrine disruptor screening; training programmes. Presence of major consulting firms and CROs, making ABIM a key moment to track market trends. Why is biocontrol accelerating? The CEHTRA perspective Regulatory developments, pressure to reduce conventional pesticide use and growing interest in natural solutions are creating a favourable environment for innovation. CEHTRA supports this transition by providing: comprehensive regulatory support; optimised dossier strategies; advanced digital solutions (CEHTRAWATCH, Simply Predict); dedicated training programmes. Conclusion: ABIM 2025 confirms the central role of biocontrol in European agriculture ABIM 2025 highlighted a fast-evolving sector, driven by: rapid scientific innovation; complex regulatory requirements; an increasing need for specialised support. Thanks to its recognised expertise, CEHTRA continues to play a key role in guiding biocontrol, biostimulant and natural substance manufacturers through a rapidly changing regulatory landscape. Are you developing a biocontrol product, a natural substance or a biostimulant?

Safety of cosmetic ingredients: a legal and ethical requirement The use of any new cosmetic ingredient must be safe. That is a legal obligation according to Article 3 of the European Cosmetic Regulation and in other cosmetic-related laws and standards throughout the world, but also a moral one, as it would be unethical to place on the market a substance that is toxic, or whose toxicity is unknown and for which safe exposure cannot be demonstrated. Cosmetic safety assessment without animal testing In Europe first, since 2009 -and in more parts of the world each year- animal testing is no longer authorised to demonstrate the safe use of cosmetic ingredients. Many toxicological endpoints must be assessed to demonstrate the safe use of an ingredient: some of them have been assessed in vitro for decades, like mutagenicity, for which the Ames test was first described in the 1970s.Others have been greatly improved in vitro since the enforcement of the European Cosmetics Regulation, such as skin sensitization, for which dozens of in vitro and in chemico models have been proposed since 2009, and several now have an OECD-dedicated guideline (DPRA, U-SENS, GARDskin assay, etc.). The challenge of systemic toxicity endpoints But some endpoints are complex to summarize into a simple in vitro assay, like those related to systemic toxicity (i.e. toxicity that impacts organs not directly exposed to substance, like internal organs). Systemic toxicity includes general toxicity, which can affect organs; carcinogenicity, the induction of cancer by chemicals; and developmental and reproductive toxicity (DART), i.e. toxicity that impact reproductive function or toxicity to the developing foetus. The latter is particularly complex to study, because embryonic and foetal developmental is a long process, starting with a single cell and evolving into a million-cell organism, and it includes many intermediate steps with different sensitivities to chemicals at various doses. The AOP concept Therefore, to simplify DART assessment, the first step consists in identifying a Molecular Initiating Event (MIE), i.e. how a chemical may interact with cellular receptors or enzymes. An MIE leads to a Key Event (KE): a change induced by this chemical interaction between the target and the xenobiotic (i.e. the studied chemical substance -from the Greek "ξένος", xenos, "foreign"). A Key Event then leads to an Adverse Outcome (AO), i.e. a "visible" effect, such as a malformation or reduced fertility in the context of DART. The combination of an MIE, KE, and AO defines an Adverse Outcome Pathway (AOP). Integrated Testing Strategies (ITS) Hence, assays that target a specific AOP may be developed, making DART testing easier to transpose in vitro using simplified models. On the other hand, that also means that several assays, screening several AOPs, are needed to get an overview of the adverse potential of a xenobiotic. Moreover, as any assay always has pitfalls and limitations, combining them reduces the risk of inconclusive results. That is the solution proposed by Burbank et al (2023), which consists in an integrated testing strategy, based on a set of three assays that each show satisfactory predictive capacity, but perform even better when combined, in what is called a "2 out of 3" approach: two tests leading to the same conclusion (positive or negative) determine the overall outcome for the tested substance. The third test is performed if the first two do not show the same conclusion, or to confirm the existing result. If such an ITS leads to a positive conclusion (i.e. that the substance may induce developmental adverse effects), further investigations can subsequently be performed to assess the potential risk, such as PBPK modelling to refine exposure assessment or additional tests to better understand the substance's mode of action. In vitro assays targeting specific AOP steps Several in vitro tests exist, most of them focusing on one specific step of one AOP, like the ER and AR transactivation tests, which evaluate the binding of test substances with Estrogen and Androgen Receptor. This is a typical example of MIE/KE-based assay: the test substance interacts with receptors, and this interaction is directly observed via the expression of genes associated with these receptors (the luciferase gene in most case). Other assays such as those developed by ReproTracker focus on Adverse Outcomes: in a nutshell, morphological changes of exposed cells are observed, and abnormal changes are concluded as positive for teratogenicity potential. However, the main results of ReproTracker assays are the measurement of molecular biomarkers related to cells differentiation. So the main step is the identification of key event, adverse outcome observation is a secondary result. In silico approaches and computational prediction Tests based neither on animal nor in vitro also exist: they are in silico methods, based on computational models. The OECD QSAR Toolbox provide different, free models either based on structure-activity relationship, predicting the effect of a chemical based on its chemical formula and design, or based on its analogy with other known chemicals. These expert models provide various predictivity and are often better at detecting toxic chemicals than detecting non-toxic chemicals, as more data exist, more articles are published, about the toxicity of chemicals than about their non-toxicity ! The development of artificial intelligence and neural networks make those models always more predictive (e.g. Lee et al, 2025), but we can expect a 'glass ceiling', as the predictivity of such models is based on accumulated in vivo data, which will not be infinite. At CEHTRA, our scientific approach builds on these advanced silico methods to develop a robust toxicological profile for each ingredient in our Cosmetick database: toxicological profiling by our toxicologists includes a routine screening with such QSAR tools to provide the highest level of knowledge on each substance. These tests were developed to address the great complexity of embryo and foetus development. To a certain extent though, some assays can still be performed on whole organisms: indeed, the use of animal embryos is still authorised, even in the EU, for the safety assessment of cosmetic ingredients. European directive 2010/63, on the protection of animals used for scientific purposes, applies to "live non-human vertebrate animals, including independently feeding larval forms" and is the legal basis to define "animal testing", even though it is not referenced in the European Cosmetics Regulation. Therefore, it is generally considered that tests performed on embryos, are acceptable for cosmetic ingredient assessment. Moreover, these models have the advantage to be based on complete organisms, authorizing the direct observation of malformations, combined with controlled exposure conditions and great knowledge of the models, as some vertebrate species embryos (e.g. zebrafish), have been reference models in embryology for decades. Ethical issues and possible future regulatory changes However, some groups, associations, NGOs, and governments have raised ethical concerns on this use of animal embryo models, and an update of European regulations might soon forbid the use of such models, and any animal-based ones (vertebrate or not) for cosmetic testings. Until then, assays such as the Zebrasfish Embryotoxicity Test or even the Frog Embryo Teratogenicity assay on Xenopus are authorised and provide quite predictive results regarding teratogenicity assessment (e.g. Leconte & Mouche, 2013). Conclusion In conclusion, a significant number of tests are now available to assess some of DART endpoints. A specific set of these performed under appropriate conditions can produce good predictive results. Like many tests, however, most of these results are hazard-based, i.e. they provide a qualitative response (positive or negative), and not a quantitative one that can support the establishment of a reference value. Whether you need assistance in monitoring such assays, performing in silico analyses with our experts from Simply Predict , or designing an assessment strategy, do not hesitate to reach out to Cehtra for DART-related topics!

On 26 November 2025 , the European Parliament and the Council adopted Regulation (EU) 2025/2509 , a major update that repeals Directive 2009/48/EC  to raise toy safety standards  across the European Union. The regulation defines a toy  as any product designed for play by children under 14 , even if that function is not exclusive. Children  are a particularly vulnerable group, and ensuring their protection from physical and chemical risks  is crucial. This regulation aims not only to safeguard young consumers but also to harmonize toy safety rules across EU Member States , including the online marketplace . Chemical Safety of Toys: Ban on Harmful Substances One of the major advances of this regulation concerns chemical safety. Generic bans now apply to the most dangerous substances: carcinogenic, mutagenic, or toxic for reproduction (CMR) substances, as well as endocrine disruptors and respiratory and skin sensitizers. The regulation also introduces: A strict ban on the intentional use of PFAS (per- and polyfluoroalkyl substances) and certain bisphenols, to protect the developing hormonal system of young children. A list of substances subject to specific limit values , such as heavy metals, nitrosamines, and allergenic fragrance substances. The European Chemicals Agency (ECHA) plays a central role in assessing these risks and managing potential exemptions, which are only granted if no safe alternative exists. Responsibilities of Manufacturers, Importers, and Distributors under EU Toy Safety Regulation 2025/2509 The regulation clarifies the obligations of each operator: Manufacturer Responsibilities Conduct a full safety assessment Prepare technical documentation Create a digital passport containing compliance and safety information Importer Responsibilities Ensure the manufacturer has fulfilled their obligations before placing the product on the EU market Responsibilities of Distributors and Online Marketplace Providers Act diligently and ensure safety warnings are clearly visible, even during remote purchases Immediately inform authorities via the Safety Business Gateway portal and take corrective actions, such as withdrawing or recalling the toy, in case of a dangerous product Safety Gate Alerts 2025: Chemical Hazards in Toys As an example in 2025: 326 chemical alerts were recorded on 261 toys , concerning hazardous chemical substances now mostly covered by the new Regulation. Methodologies for Assessing Children’s Exposure to Chemicals in Toys Methodologies for assessing children’s chemical exposure have evolved over the years: Timeline of Methodologies 2002:  Information sheet on children’s toys – Assessing consumer risks (RIVM report 612810012/2002) 2008:  Chemicals in toys – General methodology for assessing chemical safety of toys – Focus on elements (RIVM report 320003001/2008) 2003-2024:  European Commission guidance on toy safety to help supply chain actors comply with the Directive 2016:  ANSES study on children under 3 years using plastic toys 2024:  OECD study on methodologies for estimating children’s exposure to toys These publications gradually build a solid methodological framework for risk assessment, particularly regarding chemical safety. CEHTRA aligns with this approach: these methodologies structure our evaluations, and we support actors in transforming these references into product compliance evidence. CEHTRA: Your Partner for Securing Toy Safety Regulation (EU) 2025/2509 represents a major step forward for toy safety in Europe, strengthening the protection of children and clarifying the responsibilities of all supply chain actors. Faced with these new requirements, it is essential to rely on solid regulatory expertise to ensure product compliance and protect young consumers.

Since 13 December 2024, the European consumer landscape has changed drastically with the application of Regulation (EU) 2023/988 , better known by its acronym GPSR (General Product Safety Regulation) . Less than a year later, an important milestone completed the framework: on 21 November 2025, application guidelines were published. They provide the long-awaited clarifications on the interpretation of the text and its operational requirements. GPSR: A Universal Safety Net for All Consumer Products The GPSR applies to all non-food consumer products , whether new, second-hand, repaired, or refurbished. Its strength lies in its transversal scope: it applies whenever there is no stricter specific provision in EU harmonization legislation. The goal is simple: no dangerous product should slip through the safety net, whether sold in physical stores or online. General Safety Obligation: Ensuring Safe Products on the Market The GPSR is abased on a general safety obligation : economic operators may only place safe products on the market. A safe product is defined as: "any product which, under normal or reasonably foreseeable conditions of use, including the actual duration of use, does not present any risk or only the minimum risks compatible with the product’s use, considered acceptable and consistent with a high level of protection of the health and safety of consumers." To achieve this, the regulation requires a rigorous methodological approach. Each manufacturer must now carry out an internal risk assessment  before placing any product on the market. Risk is defined as "the combination of the probability of an occurrence of a hazard causing harm and the degree of severity of that harm."  This assessment must be recorded in technical documentation , proportionate to the product's complexity, and retained for 10 years . Main Product Safety Assessment Criteria Under the GPSR Product characteristics:  Design, composition, packaging, and instructions. Consumer categories:  Special attention is given to vulnerable consumers  (children, elderly, people with disabilities). Misleading appearance:  Products mimicking foodstuff or particularly attractive to children (food imitations) are specifically targeted. New technologies:  Cybersecurity, machine learning (AI) functions, and software updates are now integral to the safety assessment. Traceability and Notification: New GPSR Obligations for Manufacturers and Importers The GPSR modernizes market surveillance  through two key platforms: Safety Gate:  The former RAPEX system, renamed, for information exchange between authorities on dangerous products. Safety Business Gateway:  A mandatory portal for companies. Any manufacturer or importer aware of a serious accident or a dangerous product on the market must notify through this single access point. For example, in 2025, 2,755 chemical and environmental alerts  were reported across various consumer products. European Tools and Guidelines to Comply with the GPSR The GPSR relies on a set of guides and resources  provided at the European level. They are a useful starting point to understand requirements and structure a compliance approach, but operational implementation often requires dedicated expertise , particularly when demonstrating and documenting risk levels robustly. SAGA: A First Qualitative Approach To support risk assessment, the Commission provides SAGA (Safety Gate Risk Assessment)  via the Safety Gate ecosystem. This tool can provide a qualitative risk analysis  which can be used as a first tiered approach (hazard, exposure, severity/probability) with models adapted to different product types. However, this approach alone is often insufficient when precise quantitative risk levels  must be justified. Blue Guide and GPSR Guidelines for Businesses For the general implementation framework, operators can rely on the Blue Guide  on the application of EU product rules. More specifically, on 21 November 2025, the Commission published dedicated guidelines: On the application of the general product safety regulation (GPSR)  by businesses On the practical implementation of the Safety Business Gateway These texts aim to guide and harmonize practices while largely referencing existing EU standards, sector-specific requirements, and risk assessment methodologies already used at the EU level. Focus on Chemical Risks: Aligning With REACH When a product contains chemicals chemical component  (substances, emissions, migration, skin contact, etc.), the dedicated risk assessment benefits from approaches consistent with REACH , including hazard characterization, exposure scenarios, risk characterization, and risk management measures. This is precisely the methodological foundation CEHTRA  uses daily to produce robust, documented assessments aligned with European expectations, useful in a GPSR compliance approach . Conclusion: Ensure Your Products Comply with the GPSR The GPSR (EU Regulation 2023/988)  strengthens consumer product safety in Europe and imposes strict obligations on manufacturers and importers for risk assessment, traceability, and notification. To ensure your products fully comply and protect consumers, it is essential to work with experts. Are you affected by this regulation?

On 13 January 2026, the European Commission’s Joint Research Centre (JRC) published a new report: “JRC technical proposal on EU harmonised waste sorting labels under the packaging and packaging waste regulation”. ( Available here: JRC Publications Repository - JRC technical proposal on EU harmonised waste sorting labels under the packaging and packaging waste regulation ) More than just a design report The document is a technical blueprint to support the European Commission in developing future, harmonised packaging-sorting instructions, so consumers and producers encounter the same logic across Member States and packaging can circulate smoothly within the Single Market.  This timing is important because the Packaging and Packaging Waste Regulation (PPWR) applies from 12 August 2026, and the Commission is expected to use the JRC work as an input when preparing the secondary legislation on labelling. What the JRC report is proposing  At its core, the JRC proposes a harmonised system of consumer-facing labels for packaging and waste receptacles (bins), built to work across Europe’s very different collection and sorting systems.   The key idea is intuitive: matching labels so the label you see on packaging corresponds to what you should look for on the bin (and vice-versa).   The report serves as evidence-based input for the Commission services, especially DG Environment, to support the planned implementation measures of the PPWR (the JRC aims to inform the Commission’s implementing acts mentioned in the PPWR).  Built from behavioural evidence, not “designer taste”  One of the strongest signals in the report summary is the methodology behind it. The JRC says the proposal is grounded in:  extensive desk research  empirical evidence from citizen workshops, surveys, and experiments  expert stakeholder workshops and consultations   That matters, because sorting labels only work if they work in real kitchens, offices, and public spaces under time pressure, in different languages, and with varying levels of recycling knowledge. “Flexible, yet harmonised”: the balancing act  The JRC repeatedly frames the challenge as finding the sweet spot between EU-wide harmonisation and practical flexibility for Member States and real-world packaging constraints.   In practice, that balancing act shows up in three main design questions:  What should the label communicate?  The proposed “conceptual approach” focuses on informing consumers about material composition and providing clear sorting instructions, reinforced through matching labels on bins.   Determining the Appropriate Level of Label Granularity  A single “plastic” label offers simplicity but may be overly broad, especially in systems that differentiate between rigid and flexible plastics or where composite materials create confusion. According to the JRC summary, the proposed approach aims for a level of granularity that defines distinct labels based on both theoretical and practical considerations. External feedback on the JRC work indicates that early prototypes explored a range of material categories and subcategories. For instance, one industry analysis describes an initial prototype with eight material categories, including subcategories like “soft” vs “hard” plastics.  What should the label look like across 27 markets?  The visual approach aims to ensure the label both stands out and is understood across Member States, while allowing enough flexibility to work on-pack and on bins as you can see on the figure below.    However, even before the Commission locks anything in, the labelling conversation is already contentious. Several industry groups have publicly warned that heavy reliance on text and/or colour could recreate fragmentation because text triggers translation needs and can easily drift into national variants.   The JRC summary itself acknowledges the reality: the proposal includes compromises, identifies challenges, and flags future work needs given the complex interplay of regulatory requirements, stakeholder preferences, and practical limitations.  In other words, this is not presented as a final “perfect” answer, but as a structured, research-backed basis for the Commission to build on.  What this means for brands, retailers, and compliance teams  If you put packaged goods on the EU market, this is the moment to treat waste-sorting labels as a system change, not a minor artwork update. A few practical implications stand out:  Data discipline becomes design discipline. If labels need to reflect material composition reliably, internal packaging specifications (and component-level bills of materials) have to be clean, current, and auditable.  Space on-pack will be a constraint. Expect tension between information richness and small-format packaging realities especially if multiple components need instructions.  Consistency across SKUs will matter. Harmonisation is partly about consumer learning: the faster people recognise a label family, the better it performs.  Conclusion and next step  Under the PPWR, 12 August 2026 is a key milestone, as it is the date of general application of the Regulation and the deadline for the Commission to adopt implementing acts specifying harmonised labelling requirements. These implementing acts are adopted in 2026, while the harmonised labelling obligations take effect from 2028.  The bottom line: the JRC has now provided a concrete, evidence-backed proposal. For stakeholders, it’s crucial to begin reviewing the proposed direction now, as once the Commission’s act is adopted, the implementation timeline will accelerate rapidly.  CEHTRA supports you in implementing these regulations. Contact us today to learn more about how we can help you.  References  https://www.europen-packaging.eu/news/joint-industry-statement-on-wsl   JRC Publications Repository - JRC technical proposal on EU harmonised waste sorting labels under the packaging and packaging waste regulation   CEHTRA supports packaging stakeholders in anticipating and complying with the new PPWR requirements, particularly in terms of labeling and waste management.

COSMETICK is a toxicological and ecotoxicological profile database, combined with a digital cosmetic risk assessment tool. It is designed to support toxicologists and safety assessors in the preparation of Cosmetic Product Safety Reports (CPSR), as well as in the safety assessment of ingredients, impurities, raw materials and fragrance compounds or fragrance concentrates.  COSMETICK enables the structuring, documentation and use of reliable toxicological data, and their direct application in cosmetic risk assessments compliant with European and international regulatory requirements.  COSMETICK: a database, a risk assessment tool… or both?  Having access to a structured toxicological profile database has become essential for the organisation of any safety assessor’s work. To meet the needs of CEHTRA’s own safety assessors, toxicological profiles were originally structured and written to be directly used in safety assessments. In parallel, and because risk assessment is a core requirement for safety assessors, COSMETICK was designed with CEHTRA toxicologists as a digital tool supporting cosmetic risk assessment for finished products and raw materials .    COSMETICK in numbers: a structured toxicological knowledge base  As of the end of December 2025, the COSMETICK database included:  toxicological profiles for 3,400 ingredients,  800 impurities,  500 fragrance substances,  and 1,900 ecotoxicological profiles.  The 3,400 raw materials included are either documented by CEHTRA for its users or entered directly and confidentially by the users themselves.  Each toxicological profile results from a rigorous and standardised process involving data collection, selection of relevant studies, and synthesis of results for all endpoints required for cosmetic risk assessment. Results are described for nine toxicological endpoints : skin and eye irritation, skin sensitisation, phototoxicity, acute toxicity, sub-chronic or chronic toxicity, reproductive toxicity, endocrine disruption, and carcinogenicity. Dermal and oral absorption data are also documented. Data gaps are clearly identified and visualised through colour-coded icons.  The data are derived from numerous recognised scientific sources (SCCS, CIR, ECHA opinions, EFSA, US EPA, etc.), as well as from peer-reviewed scientific literature and in silico approaches . All sources are precisely referenced.  Ecotoxicity is documented in accordance with REACH and CLP/GHS requirements , including PBT/vPvB assessment . It covers biodegradability (OECD, BIOWIN), bioaccumulation (BCF, log Kow), and acute and chronic aquatic toxicity (algae, daphnia, fish), complemented by recognised QSAR models (ECOSAR). The analysis follows a weight-of-evidence approach integrating measured data and literature.  Profiles are continuously updated based on several criteria:  regulatory and toxicological developments,  human health concerns identified during user safety assessments,  and frequency of profile use.  Successive versions are retained for each profile, with documented comparisons between versions, ensuring traceability of updates and methodological consistency . For risk assessment purposes, cosmetic product types and exposure scenarios can be selected from predefined categories in line with standard safety assessment practices.    Developed by toxicologists, used in production at CEHTRA   COSMETICK was initially developed as an internal tool at CEHTRA for the preparation of Cosmetic Product Safety Reports from 2018 onwards. Designed by and for toxicologists , it was made available online in 2021 under a licensing model:  COSMETICK BASIC , providing access to the toxicological profile database,  COSMETICK ADVANCED , providing full access to the database and to cosmetic risk assessment functionalities.  The coexistence of the internal CEHTRA tool and the online user version ensures that users benefit from all improvements identified by CEHTRA toxicologists for their own daily practice. These improvements stem from practical needs (export formats, colour-coded user-friendly displays, formula duplication) as well as methodological developments (reverse calculation for raw materials, QRA2, results by IFRA categories). As a result, users can be confident that their cosmetic risk assessments incorporate the most up-to-date scientific and methodological approaches that digital automation can support. Data personalisation further ensures that each assessment remains specific to the company’s choices and practices.    What does a toxicological profile look like in COSMETICK?  A toxicological profile in COSMETICK includes full substance identification (INCI name, synonyms, CAS number), relevant toxicological data, toxicological reference values , colour-coded warnings , and a structured scientific summary.  For each endpoint, the profile summarises study results, identifies critical effects, and provides the toxicological reference values used for risk characterisation: LOAEL, NOAEL, NESIL, and non-effect, irritant or sensitising concentrations . The selected Point of Departure (PoD) is justified. Missing data are explicitly identified to help the safety assessor define appropriate follow-up actions.    Warnings and signals of concern  Colour-coded warnings allow rapid visualisation of critical toxicological concerns and data gaps. They provide a key decision-support tool, enabling the safety assessor to quickly identify potential issues related to a substance, raw material or formulation before assessing the actual risk based on concentration and intended use. Ecotoxicological profiles are also ranked according to increasing levels of concern.    Example: a preservative  Phenoxyethanol (CAS No. 122-99-6) is authorised as a cosmetic preservative under the European Cosmetic Regulation, up to a maximum concentration of 1% . Based on CEHTRA’s experience over the past four years, it is the most frequently used preservative .  Phenoxyethanol has a broad antimicrobial spectrum, effective against Gram-negative bacteria (e.g. Pseudomonas aeruginosa ), Gram-positive bacteria ( Staphylococcus aureus ), and yeasts ( Candida albicans ). Its activity is attributed to inhibition of microbial DNA/RNA synthesis and increased cell membrane permeability.  In 2016, the SCCS evaluated systemic effects and concluded that phenoxyethanol is not classified as reprotoxic and is only a rare skin sensitiser , considering it one of the best-tolerated preservatives. Systemic toxic effects were observed only at oral or dermal exposures approximately 200-fold higher than consumer exposure levels from cosmetics. Consequently, the SCCS concluded that phenoxyethanol is safe for all consumers, including children of all ages, when used up to 1%.  Although its irritant properties are well established, it remains well tolerated at authorised levels, without inducing skin irritation or sensitisation. Some rare discomfort reactions (stinging, tightness) may occur, particularly in cases of co-exposure with other irritants. This illustrates the importance of the safety assessor’s expertise, which goes beyond bibliographic data to evaluate safety under realistic conditions of use, such as daily facial application. While such discomfort does not represent a major health risk, it is typically undesirable for both consumers and brands.  Phenoxyethanol is classified as STOT SE 3 (H335: May cause respiratory irritation) under CLP Regulation No. 1272/2008. Very rare cases of allergy have been reported and must be assessed case-by-case depending on population, skin type and product type.  The substance is neither phototoxic nor genotoxic and shows low acute toxicity. Systemic toxicity is characterised by a sub-chronic study identifying a NOAEL of 500 mg/kg bw/day (357 mg/kg bw/day for daily administration), which adequately protects against reproductive effects observed at higher doses (SCCS, 2016; Api et al., 2025).  Available receptor binding studies do not suggest endocrine activity. Nevertheless, attention remains warranted pending conclusions from ECHA, which included phenoxyethanol in its Endocrine Disruptor Assessment programme under the Biocidal Products Regulation (assessment ongoing as of 21 August 2025).    From ingredient to finished product: risk assessment in practice  Example 1: cosmetic product with a risk of skin sensitization   The product assessed is a facial sunscreen used daily. It contains the colourant CI 77288. Several cases of allergy have been reported in the literature for various chromium(III) oxides, as highlighted by CORAP in 2022. In the absence of specific skin sensitisation characterisation, and particularly of quantitative data, the risk of sensitisation at 0.1% cannot be excluded. The risk is considered likely, leading to an unfavourable safety conclusion.  Example 2: cosmetic product with insufficient MOS  In a product intended for infants, caprylyl glycol is used at 0.5%. The associated Margin of Safety is insufficient, indicating a probable risk of systemic toxicity. The NOAEL is derived from a sub-chronic OECD 408 study. At higher doses, developmental effects may occur and are currently under regulatory scrutiny, potentially leading to harmonised reprotoxic classification (ECHA ARN on 1,2-ethanediols and their carbonates, 2021). Thus, although the Margin of Safety based on a robust toxicological reference value is insufficient, additional concerns are flagged by the “Reprotoxicity” and “Irritation” warnings . At the assessed concentration, irritation is not expected, and lower exposure levels would be considered safe and can be readily calculated.    COSMETICK and international regulatory requirements  COSMETICK toxicological profiles are prepared in accordance with Annex I of the European Cosmetic Regulation (EC) No. 1223/2009 and SCCS recommendations for CPSR preparation. This methodology reflects principles widely recognised at the international level. For example, China’s CSAR regulation requires documented safety justification based on comprehensive toxicological profiles covering all relevant endpoints. Similarly, the US Modernization of Cosmetics Regulation Act (MoCRA) requires safety substantiation based on reliable and relevant toxicological data for each ingredient. COSMETICK fully aligns with this international approach to cosmetic risk assessment .    Licences and access to COSMETICK   R&D and toxicology teams may limit their needs to consultation of toxicological profiles, available through COSMETICK BASIC . More comprehensive needs — including finished product risk assessment, raw material use evaluation or fragrance concentrate assessment — are addressed through COSMETICK ADVANCED .  Confidential raw materials can be integrated, and users may also include their own toxicological data to personalise reference values.    References  SCCS, Notes of Guidance for the Testing of Cosmetic Ingredients and their Safety Evaluation , 12th revision  Regulation (EC) No 1223/2009  China Cosmetic Supervision and Administration Regulation (CSAR), NMPA  US FDA – Modernization of Cosmetics Regulation Act of 2022 (MoCRA)     COSMETICK: an established reference for digital cosmetic risk assessment   COSMETICK is a reference digital tool for cosmetic risk assessment, combining a structured toxicological and ecotoxicological database, a robust scientific methodology and decision-support functionalities. It is designed to sustainably support toxicologists, safety assessors and R&D teams in an ever-evolving regulatory landscape.  Discover how COSMETICK integrates with the regulatory requirements of the cosmetics market.

In 2025, CEHTRA continued its mission to support industrial companies, institutions and regulated stakeholders in a context marked by increasing regulatory complexity and growing challenges related to the protection of human health and the environment. This year was a structuring one for the group, with the launch of new digital tools, the evolution of long-standing services, the strengthening of our expertise and the development of strategic collaborations. CEHTRAWATCH: a global, expert regulatory monitoring platform One of the key highlights of 2025 was the launch of CEHTRAWATCH, a digital solution dedicated to international regulatory monitoring. CEHTRAWATCH enables users to: scan, track and receive alerts on more than 100 regulatory and toxicological lists, cover over 40 countries, receive personalised alerts based on substances or topics of interest, benefit from continuous updates validated by CEHTRA experts. Designed as a decision-support tool, CEHTRAWATCH helps companies save time, anticipate regulatory risks and work with reliable, structured information, while maintaining access to human expertise. RASafe: from Industrial Hygiene to a global Risk Assessment approach Historically focused on supporting chemical industry players through its Industrial Hygiene activity, CEHTRA evolved this offering in 2025 into a transversal service: Risk Assessment & Safety (RASafe). This transformation is based on a clear observation: chemical risk assessment , and particularly exposure assessment , remains a frequently underestimated pillar of regulatory compliance processes. A structured approach built on three complementary pillars RASafe is now organised around three core areas: Toxicological assessment: Hazard identification, data analysis and derivation of relevant reference values. Exposure modelling and estimation: Assessment of occupational and consumer exposure using recognised methodologies and tools. Regulatory support and training: Audits, preparation of technical documents (CSR, SDS…), and training on risk assessment tools and regulatory compliance, particularly under REACH. A transversal mission Through RASafe, CEHTRA supports industrial companies, public bodies and consultants in better understanding, assessing and managing chemical risks, with a central objective: protecting human health and the environment.   CEHTRA blog and webinars: making regulation more accessible The year 2025 also marked the launch of the CEHTRA blog, designed as a space for sharing knowledge and educational resources. Each week, new articles are published to: decode regulatory news, explain key texts and obligations, help stakeholders navigate the regulatory landscape. In parallel, several webinars were organised to provide practical insights into current regulatory topics and to encourage direct exchanges with our experts.   Acquisition of Prosacon: strengthening and expanding group expertise In 2025, CEHTRA continued its development with the acquisition of Prosacon, expanding the group’s scope of expertise and strengthening its ability to address increasingly transversal regulatory challenges. This acquisition is part of a strategy of controlled growth, aligned with the concrete needs of our clients.   Flex+: agile outsourcing of expert resources The launch of Flex+ responds to a need identified in the field: enabling companies to quickly outsource expert resources, while ensuring high-quality deliverables and regulatory compliance. Flex+ offers a flexible approach, adapted to operational constraints and regulatory challenges faced by organisations.   together Alliance: collectively addressing ethanol-related challenges in biocides In response to complex regulatory issues related to ethanol in biocidal products, CEHTRA launched the Together Alliance in 2025. This initiative is based on the belief that certain regulatory challenges require a collaborative approach, encouraging knowledge sharing and the development of joint solutions.   Digital and artificial intelligence: supporting human expertise During the CEHTRA 2025 General Meeting, all group entities came together to work on issues related to digital transformation and artificial intelligence. The objective is clear: to explore how digital tools and AI can support experts’ daily work, improve process efficiency and enhance the quality of support provided — without ever replacing human expertise. 2025: a structuring year in support of regulatory compliance The year 2025 was marked by the commitment of our teams, the trust of our clients and close collaboration with our partners.Each project carried out this year helped strengthen our ability to support regulated stakeholders facing ever-higher requirements in terms of regulatory compliance, chemical risk management and regulatory monitoring. CEHTRA enters 2026 with the same ambition: to offer useful tools, rigorous expertise and operational support, closely aligned with real-world challenges.

Understanding the regulatory and industrial challenges associated with this substance subject to authorisation Introduction Ethylenediamine (EDA, CAS 107-15-3) is a chemical compound widely used as an intermediate in many industrial processes, such as chemical synthesis, resin manufacturing, chelating agents, and additives for lubricating oils. However, due to its hazardous properties, in particular its classification as a respiratory and skin sensitiser, EDA has been identified as a Substance of Very High Concern (SVHC). At this stage, it is included in the 11th Recommendation List for a possible inclusion in Annex XIV of the REACH Regulation. As a reminder, intermediate uses are exempt from REACH authorisation. A future inclusion in Annex XIV would therefore apply only to non-intermediate uses. This overview aims to explain why EDA is concerned by the REACH authorisation process, which stakeholders could be impacted, and how CEHTRA supports its clients throughout this strategic process. Why is Ethylenediamine subject to authorisation? EDA presents several critical hazards, in particular: Respiratory sensitisation (Skin Sens. 1, Resp. Sens. 1), with a high risk of severe allergic reactions, even at low exposure levels. These properties led to its identification as a Substance of Very High Concern (SVHC). When a substance is included in Annex XIV of REACH, its use becomes prohibited after a sunset date, unless an authorisation is granted for a specific use. The objectives of REACH authorisation applied to EDA are to: control health risks linked to exposure, particularly in occupational settings, encourage companies to identify safer alternatives, allow only those uses for which no technically or economically viable alternative is available. Who is concerned? The following stakeholders would be directly concerned by authorisation: Industrial users of EDA for non-intermediate uses, in particular: formulation of resins, adhesives, coatings or inks, manufacture of finished products containing EDA, certain applications in lubricants, additives or treatment products, Importers placing this substance on the market for a specific use. Companies along the value chain when they rely on a product containing EDA. As for any Annex XIV substance, authorisation is linked to the use, not to the substance itself. A company may be authorised for one use, but not for another. When should an authorisation be requested? To date, Ethylenediamine (EDA) has not yet been formally included in Annex XIV of REACH. It is currently listed in the 11th Recommendation List, meaning that a future inclusion is being considered, potentially by 2026. As a result, the key regulatory dates, namely the Latest Application Date (LAD) and the Sunset Date, are not yet defined. They will only be set once a potential inclusion in Annex XIV is confirmed. Once these dates are published, the application must be submitted before the Latest Application Date (LAD). Submitting the application before the LAD would then allow: continued use of EDA after the Sunset Date, while the ECHA and the European Commission finalise their assessment, maintenance of industrial continuity without interruption. Once granted, the authorisation allows the use to continue under strictly controlled conditions. As a reminder, the full REACH authorisation procedure is described in detail in our dedicated article. For any questions or to assess your situation regarding Ethylenediamine, our experts are at your disposal.

In recent years, few regulatory topics have attracted as much attention as endocrine disruptors, chemicals capable of interfering with hormone systems in humans and wildlife. Their potential effects on development, reproduction, and environmental health have prompted increasingly rigorous scrutiny across the globe. Within the European Union, two major legislative frameworks govern how such substances are assessed: Regulation (EC) No 1107/2009 for plant protection products (PPPs) and Regulation (EU) No 528/2012 for biocidal products (BPs). In 2018, the EU implemented a harmonised set of scientific criteria for determining whether a substance exhibits endocrine-disrupting (ED) properties. Now, after several years of applying these criteria, the European Commission has evaluated the experience gained, what worked, what stalled, and what still needs to change. The findings illuminate both the scientific complexity behind ED assessments and the administrative challenges facing regulators and industry alike. This article breaks down the key insights from this extensive review.   Why the EU Updated Its Approach When the PPP and BPR regulations were originally adopted, they included interim criteria for ED identification, with a clear requirement for the Commission to develop more scientifically robust standards. These updated criteria came into force in mid- and late-2018, shaping all ongoing and future assessments of active substances. To support implementation, the European Chemicals Agency (ECHA) and the European Food Safety Authority (EFSA) jointly developed comprehensive guidance explaining how to evaluate ED properties. This guidance became the backbone of the regulatory process, but it also introduced substantial new workloads for both applicants and evaluators.   What Has Happened Since the New Criteria Came into Effect? 1. Plant Protection Products (PPP) As of January 2025, endocrine disruptor assessments had been completed for 104 active substances used in plant protection. Key outcomes: 9 substances were identified as endocrine disruptors , either for human health, non-target organisms, or both. Interestingly, ED properties were not  the sole or decisive reason for their non-approval or non-renewal, other safety concerns also played major roles. 95 substances were concluded not to have ED properties  and therefore remained approved or were renewed. 259 substances are still under assessment , illustrating how resource-intensive ED evaluations have become. Delays have been a major challenge. Many renewal procedures already in progress when the new criteria took effect had to be paused so EFSA could request additional data, a process that could take up to 30 months. Once submitted, these data needed to be reviewed first by Rapporteur Member States and then through EFSA’s peer-review system, creating delays that often exceeded three years overall. A significant bottleneck has been the shortage of experts trained to evaluate complex toxicological and ecological endocrine data. Another issue: the limited availability of certified laboratories capable of performing the highly specialised studies required. Some applicants have challenged ED conclusions in court (most notably the case of mancozeb) but so far, no ruling has overturned the adequacy of the ED assessments themselves.   2. Biocidal Products (BP) For biocides, the pace and complexity of ED assessments have likewise influenced regulatory timelines, particularly the EU’s long-running review programme for “existing” active substances (those on the market before 2000). As of early 2025: Eight substances have been identified as endocrine disruptors  for both human health and the environment. Some were not approved due to ED concerns; others were approved using derogations where no suitable alternatives exist. Seventeen substances were concluded not to have ED properties . Twenty-nine substances could not be conclusively assessed , either because data were insufficient or because parallel concerns made a full ED conclusion unnecessary at the time. ED assessments are ongoing for 169 substances , with 25 older substances awaiting evaluation during their renewal phase. Like PPPs, biocidal ED assessments have faced shortages of experts and laboratory capacity. Some Member States adopted a stepwise approach, requesting limited data first, then additional tests, which unintentionally prolonged evaluations. Competent Authorities have since agreed that when in vivo studies are clearly needed, they should be requested upfront to avoid unnecessary delays. The cumulative burden has been significant enough that the EU extended the biocides review programme until 31 December 2030 , highlighting the scale of the task ahead.   Shared Challenges Across Both Sectors Across PPPs and BPs, several consistent issues have emerged: 1. Limited Scientific Expertise ED assessment is among the most complex areas of modern toxicology. Member States continue to face shortages of skilled experts in endocrinology, ecotoxicology, and evidence synthesis. 2. Insufficient Laboratory Capacity Many ED-relevant studies require specialised test facilities, yet the number of certified labs capable of conducting these tests remains limited. This creates bottlenecks for applicants needing to generate new data. 3. Heavy Data Requirements ED evaluations require extensive literature searches and reviews, including mechanistic, in vivo, and ecological data. Processing this volume of information significantly increases assessment time. 4. Ongoing Legal and Technical Interpretation Questions Some applicants contest ED conclusions, while others question when exactly additional data should be considered sufficient. Though the core criteria remain robust, procedural uncertainties persist.   Do the Current ED Criteria Still Hold Up? Despite operational challenges, the Commission’s assessment confirms that the scientific ED criteria remain valid , scientifically sound, and fit for purpose. They allow for consistent identification of substances with endocrine-disrupting properties, ensuring a high level of protection for human health and the environment. What is clear, however, is that implementation, not the scientific basis, is the limiting factor . Building expertise, expanding laboratory capacity, and streamlining data requests will be crucial steps in meeting future regulatory deadlines.   Looking Ahead The EU’s experience with ED criteria underscores a broader truth: robust scientific regulation is essential, but it must be matched with strong operational capacity. As Member States and EU agencies continue to refine processes and invest in scientific expertise, the assessment of endocrine disruptors should become more efficient without sacrificing rigor. For researchers, industry, and policymakers, this review offers a roadmap of where attention is needed most. And for the public, it reaffirms the EU’s commitment to grounding chemical safety decisions in the best available science; while constantly scrutinising how that science is put into practice. If your organisation is navigating the challenges of ED assessments under PPP or BPR, our CEHTRA experts can support you with strategic, regulatory, and scientific guidance tailored to your substances and timelines.

Directive (EU) 2020/2184 establishes a harmonised framework intended to ensure the safety of materials and products that come into contact with water intended for human consumption. To achieve this objective, it introduces a central mechanism: the EUropean Positive Lists (EUPL) . These lists now constitute the single reference for determining which substances may be used in drinking water installations, whether pipes, storage tanks, treatment equipment or any other component of the network. The scope of the EUPL is defined in particular under Article 11(2)(b) and Annex V of the Drinking Water Directive (DWD).   The EUPL: Definition, Role and Scope The EUPL are unique reference lists that group together the substances, compositions or constituents considered safe for use in contact with drinking water. Their function is essential, as they make it possible to exclude any material likely to alter drinking water quality or present a health risk for consumers. Article 10 of the directive indeed requires that only materials, meaning solids, semi-solids, or liquids used for the manufacturing of a product (an item intended to be placed on the market and coming into contact with water intended for human consumption), listed on these registers may be used in installations. This requirement ensures full harmonisation at the European level and ends the differences in practices that previously existed between Member States.   Categories of Materials Covered The EUPL, presented in Commission Implementing Decision (EU) 2024/367, cover four major families of materials: Organic materials  including polymers, resins and monomers used in their manufacture. Cementitious materials , such as mortars or other cement-based components used notably in reservoirs or hydraulic structures. Metallic materials , including authorised alloys such as copper or stainless steel. Enamels, ceramics and other inorganic materials , which are included for applications requiring coated surfaces or specific components. For some of these materials, particularly organic and cementitious ones, the evaluation is based on the calculation of the MTCtap (Maximum Tolerable Concentration at the Tap). This threshold represents the maximum acceptable concentration at the point of use, defined either from ECHA opinions or limits set by the European Commission.   The Inclusion Process The inclusion of a substance in an EUPL is based on a strictly regulated scientific procedure involving a thorough risk assessment, taking into account the potential migration from the material into drinking water under the most unfavourable conditions of use. Conformity tests are then carried out to verify the material’s safety, particularly its impact on organoleptic properties and the microbiological balance of water. When all criteria are deemed satisfactory, the substance may be included in the positive list, following the opinion of ECHA’s Risk Assessment Committee (RAC).   Regulatory Framework and Implementing Decisions The evaluation procedure is defined by Delegated Regulation (EU) 2024/369 , which sets out the information requirements and the modalities for ECHA’s assessment. In parallel, implementing acts establish the test methods used to verify the conformity of substances or compositions. The application rules of Directive (EU) 2020/2184, notably the establishment of the lists and the testing requirements, are detailed in the following implementing decisions, all dated 23 January 2024: Commission Implementing Decision (EU) 2024/367 : Establishes the European positive lists of starting substances, compositions and constituents authorised for use in manufacturing materials or products that come into contact with water intended for human consumption. This document contains the European Positive List. Commission Implementing Decision (EU) 2024/365 : Lays down the application rules of the Directive regarding methodologies for testing and accepting starting substances, compositions and constituents for inclusion in the European positive lists. Commission Implementing Decision (EU) 2024/368 : Its annexes specify that certain cementitious constituents and certain starting substances may be used without being listed in the European Positive List. This exemption depends on their level of migration and/or hazard. Consequently, information (and potentially testing) on these aspects must be obtained to determine whether the substance must be included in the EUPL.   Dynamic Lists Regularly Updated The EUPL are not static. They are subject to periodic review to take account of scientific developments, new toxicological data or technological innovations. The first lists currently include 2,042 starting substances, compositions and constituents. Each listed substance must be reassessed at least every fifteen years. The initial European lists will be drawn up from existing national lists, then reviewed by ECHA to ensure compliance with European requirements. Each entry is associated with an expiration date defined according to the characteristics of the substance and the quality of the initial evaluation. The current deadlines extend to 31 December 2028, 2031, 2034 and 2037 . To remain listed, a renewal or re-evaluation request must be submitted 18 months before the expiration date . Regulatory Procedure: From Notification of Intention to Complete Submission The evaluation process begins with a Notification of Intention (NoI)  submitted via the IUCLID platform. This notification identifies the substance concerned, the associated material category and the type of application (new inclusion, withdrawal or re-evaluation of an already listed substance). The texts provide that NoIs may be submitted from 31 December 2025 . The corresponding complete dossiers must then be submitted within twelve months, meaning that the first inclusion or renewal applications may begin as of 31 December 2026 .   Strategic Importance for Public Health and Sector Stakeholders For operators in the sector, the Directive requires constant vigilance in the selection of materials and the verification of their compliance. They must ensure that the products used are listed, anticipate upcoming revisions, and communicate clearly with users regarding the guarantees offered by this regulatory framework.   Conclusion The European Positive Lists are among the most structuring instruments of Directive (EU) 2020/2184. They ensure a high level of health protection by precisely defining which substances are authorised in drinking water installations. Their implementation is based on robust scientific assessment, regular updates and active cooperation between authorities, manufacturers and operators.

If you're a cosmetics manufacturer looking to sell your products in the European Union, it's important to understand the requirements for a Cosmetic Product Safety Report (CPSR). A CPSR ensures that your product is safe for consumers and helps to protect public health. Contact a qualified person, such as a toxicologist, to help you prepare a CPSR and ensure that your product complies with the Cosmetics Regulation (EC) No 1223/2009. Don't risk fines or legal consequences - prioritize the safety of your customers with a thorough CPSR. What is a CPSR? A Cosmetic Product Safety Report (CPSR) is a document that presents the conclusion on the safety of a cosmetic product and the rationale used by the safety assessor. The report is required in the European Union under the Cosmetics Regulation (EC) No 1223/2009. The purpose of the CPSR is to consider the expected use, list the useful information, from literature or obtained on the product, and quantify any potential risk, if identified, to demonstrate that it can be used without any risk. What does a CPSR include? A CPSR typically includes the following information: Part A: gathering information on the presentation of the product, its indications, its expected stability, compatibility with the pack, efficient preservation, information on traces, and tolerance results. Part B: presenting the conclusion, any warning if needed, the rationale to conclude on the different risks induced by the product, and the signature of the qualified safety assessor. An important part of the Safety Report is generally included in Annexes: the toxicological profiles, which must be provided for all ingredients. Who prepares a CPSR? A CPSR must be prepared by a qualified person, a safety assessor, such as a toxicologist, who has the necessary diplomas and expertise to assess the safety of cosmetic products. The qualified person may be employed by the cosmetic product manufacturer or by a third-party company that specializes in safety assessments. At CEHTRA, several of our toxicologist can sign the CPSR. Why is a CPSR important and what does CEHTRA recommends? A CPSR is important because it ensures that cosmetic products are safe for use by consumers. By identifying potential risks associated with the use of a cosmetic product, the CPSR helps to prevent harm to consumers and to protect public health. CEHTRA recommends a 1rst step before writing this report, in a pre-assessment, before starting any study. In addition, a CPSR is required by law in the European Union. Failure to comply with the requirements of the Cosmetics Regulation (EC) No 1223/2009 can result in fines and other legal consequences. Overall, the CPSR is a crucial component of ensuring the safety of cosmetic products on the market. Get expert support in preparing your CPSR and ensure your products are fully compliant with EU regulations.

Understanding REACH Authorisation: A Control Mechanism for the Most Hazardous Substances Introduction The REACH Regulation (EC No 1907/2006) aims to ensure a high level of protection for human health and the environment from the risks posed by chemical substances. Among its four main pillars, Registration, Evaluation, Authorisation and Restriction, the Authorisation process is often the most complex for non-specialists to understand. Yet it plays a critical role in managing the most hazardous substances on the European market. This article explains what REACH Authorisation is, why it exists, who is affected, how an Authorisation dossier is built, and how we support our clients throughout the process. ation est d’expliquer ce qu’est l’autorisation REACH, pourquoi elle existe, qui est concerné, et comment se constitue un dossier d’autorisation et enfin comment nous accompagnons nos clients. Why is Authorisation required? Certain chemical substances present severe hazards: carcinogenic, mutagenic, or toxic to reproduction (CMR); persistent, bioaccumulative and toxic (PBT); or endocrine disruptors. These substances are identified as Substances of Very High Concern (SVHCs) . Once an SVHC is added to Annex XIV of REACH  (the “Authorisation List”), its use is prohibited after a specified sunset date , unless a specific Authorisation is granted for defined uses. The REACH Authorisation process therefore aims to: Control risks associated with the use of these substances. Encourage substitution with safer alternatives. Allow continued use when no technically or economically feasible alternative is available. Who is concerned? The following companies may require an Authorisation: Users of a substance listed in Annex XIV. Importers or suppliers placing the substance on the market for a specific use. It is essential to note that Authorisation is use-specific , not substance-specific: a company may apply for Authorisation for one defined use, even if other uses of the same substance are banned. When should an Authorisation be submitted? It is strongly recommended to submit the application before the Latest Application Date (LAD)  for each substance. If the authorities take longer to assess the dossier, the applicant may continue using the substance beyond the sunset date while awaiting the decision. Once granted, the Authorisation allows continued use of the substance beyond the sunset date under the conditions specified. Steps of the Authorisation Process: The Authorisation workflow includes: Identification of the substance as an SVHC. Inclusion in Annex XIV. Preparation and submission of the Authorisation dossier. Evaluation by ECHA (Risk Assessment Committee – RAC, and Socio-economic Analysis Committee – SEAC). Final decision by the European Commission. Building a REACH Authorisation Dossier A REACH Authorisation dossier is a highly technical and regulatory submission. It must demonstrate that risks are adequately controlled (for threshold substances) or minimised as far as possible (for non-threshold substances such as CMRs), and that no suitable alternatives exist. The dossier includes: Justification for the Application The applicant must explain why Authorisation is needed by defining: The precise uses of the substance, including technical context, operational constraints, and sector-specific details. The quantities involved. Chemical Safety Report (CSR) This report assesses human health and/or environmental risks associated with the use of the substance. It includes: Exposure scenarios describing risk management measures and operational conditions. Risk characterisation comparing exposure levels with “safe” limits (usually derived by RAC experts). Analysis of Alternatives The applicant must demonstrate: That alternatives have been investigated. Why they are not technically or economically viable. That alternatives would reduce risks to humans and/or the environment. It is now strongly recommended to include a Substitution Plan , describing timelines, milestones, organisational structure, and reporting mechanisms related to the future switch to alternatives. Socio-economic Analysis (SEA) This analysis generally compares: The societal benefits (not only company benefits) of continuing to use the substance,vs. The human health/environmental costs of discontinuing its use. Submission and Follow-up The dossier is submitted via ECHA’s portal. Fees apply depending on company size. The evaluation period is not legally fixed and may range from 18 months to 3 years based on our experience. Once Authorisation is granted, companies must: Comply with the conditions described in their dossier, plus any additional conditions set by EU authorities. Prepare a review report  when the Authorisation expires (typically after 4, 7, or 12 years), justifying why substitution could not be completed within the initial timeframe. Key Points for Non-Experts REACH Authorisation is not automatic  and must be justified. It concerns the most hazardous substances . The dossier is highly technical and often requires collaboration across the supply chain.

What is an endocrine disruptor? In the European Union, an endocrine disruptor is defined as a substance that interferes with the hormonal system and may have harmful effects on humans and wildlife. These substances can be of synthetic or natural origin and may impact reproduction, growth, and development. In Europe, endocrine disruptors are assessed under various regulations, particularly those related to pesticides and biocides. The EFSA and l’ ECHA , as well as the l’ OCDE , have published guidance to help identify these substances. The criteria for identifying a substance as an endocrine disruptor are as follows: Endocrine activity : the substance must have endocrine activity. Adverse health effect : it must cause a harmful effect on health. Plausible biological link : there must be a plausible biological link between the endocrine activity and the adverse effect. Regulatory framework: Key milestones  2018 : assessing endocrine disruption potential became mandatory for plant protection products and biocides. April 20, 2023 : entry into force of new classifications under the CLP regulation, introducing the following categories: ED HH  (endocrine disruption for human health), Categories 1 and 2 ED ENV  (endocrine disruption for the environment), Categories 1 and 2 Upcoming or pending regulations:   Update of the Cosmetics Regulation to include the evaluation of endocrine disruptors. Upcoming REACH revisions: identification of endocrine disruptors starting at the lowest tonnage band (from 1 tonne/year). How CEHTRA can support you? In this demanding regulatory context, CEHTRA offers solid expertise and tailored services to support companies in the evaluation of endocrine disruptors.   Key services provided: Critical review of existing data: Review of available regulatory data Targeted bibliographic research and analysis Generation of new, specific data when needed: Tailored testing strategies (in vitro, in vivo) In silico screening (predictive modeling) Monitoring of specific ED-related studies Data compilation in line with the regulatory context: Robust synthesis of studies EFSA table and identification of levels of evidence Determination of classification according to CLP criteria Detailed reports for specific substances or formulations Expert statements (position papers) on ED potential for humans and/or the environment Added value: In silico screening by QSAR experts Use of digital tools to optimize analysis and related costs Tailored services for various sectors (biocides, cosmetics, plant protection products, chemicals, etc.) An experienced in-house team of ecotoxicologists and toxicologists Digital tools ED Pedia : CEHTRA also offers ED Pedia, an interactive tool that allows you to: Instantly check, via CAS number, whether a substance is likely to be an endocrine disruptor Access relevant documentation Download a PDF report of the results Request a CEHTRA expert’s opinion if needed ED Pedia relies on official substance evaluation lists to determine the level of concern regarding a substance’s ED potential.

The Directive (EU) 2020/2184, adopted on December 16, 2020, marks a pivotal change in the management of drinking water across EU. It replaces the 1998 directive (directive 98/83/EC) and aims to ensure universal access to safe and high-quality drinking water while enhancing transparency, monitoring, and risk management. This regulatory text has significant implications for water suppliers, industries manufacturing materials in contact with drinking water, as well as all stakeholders across the sector. In this article, we will explore the key objectives, new requirements, and essential details of this directive to help you understand its impact on water management practices. We will also provide a brief introduction to the positive lists, which we will explore in detail in a next article. The revision of the Drinking Water Directive (DWD) is part of the European Union's strong commitment to protecting public health and the environment by ensuring access to clean and safe drinking water. Originally adopted in 1998 and thoroughly revised in December 2020, the Directive was updated to reflect scientific advances and address emerging pollutants such as endocrine disruptors and microplastics. This revision was also a direct response to the "Right2Water" European Citizens' Initiative, emphasizing citizens' right to access high-quality drinking water. The revised DWD (Directive (EU) 2020/2184) entered into force on January 12, 2021, requiring Member States to transpose its provisions into national legislation by January 2023. Its overarching goal is to ensure that all EU citizens benefit from some of the highest drinking water standards in the world, while promoting sustainable water management and enhancing consumer confidence in tap water.   1. Key Objectives of revised DWD The main objective of this directive is to protect public health while improving the quality of drinking water across the European Union. To achieve this, the directive sets several specific goals: Public Health Protection : Drinking water must be free from chemical and microbiological contaminants that could harm health. Improved Access to Drinking Water : The directive aims to ensure universal access to safe and affordable drinking water. Enhanced Monitoring : It establishes stricter monitoring of water quality and mechanisms for risk assessment. Sustainable Water Management : The directive includes measures to protect water resources against the impacts of climate change and other environmental pressures.   2. New Drinking Water Quality Parameters and the Watch List Mechanism The revised DWD represents a substantial evolution in the EU regulatory framework for drinking water, introducing updated quality parameters and a watch list mechanism to ensure a high level of health protection in light of emerging environmental challenges. In accordance with Article 5 , Member States are required to adopt and comply with the parametric values established in Annex I , which encompass microbiological, chemical, and indicator parameters. This revision integrates the most recent scientific findings and recommendations of the World Health Organization (WHO) , leading to the inclusion of new chemical substances such as Bisphenol A, PFAS (Total and Sum) and Chlorate. These additions reflect growing concerns about endocrine disruptors , pharmaceutical residues , microplastics , and other persistent organic pollutants , thereby reinforcing the long-term safety of drinking water across the European Union. Complementing these static standards, the Directive introduces a dynamic watch list mechanism , established under Article 13 . This tool is used to proactively monitor emerging substances of concern that are not yet subject to mandatory regulatory limits but may pose a risk to human health. The European Commission is mandated to establish and periodically update this list based on scientific evidence and data provided by Member States. The first version of the watch list includes, among others, 17-β-estradiol and nonylphenol, both recognized as endocrine-disrupting chemicals.   3. Risk-Based Approach and Supply System Management The directive strengthens water quality monitoring and requires a complete risk-based approach to water safety  (Article 7). This approach is implemented in line with the Water Safety Plan (WSP) approach developed by the World Health Organization (WHO). Member States must ensure the implementation of this comprehensive risk-based approach. WSPs are proactive risk assessment and risk management approaches  recognized as the most reliable way to manage drinking-water supplies for public health protection. This approach is built on a preventive safety planning approach  and relies on the multiple-barrier approach. The EU risk framework requires three components of assessment: catchment risk (Article 8), supply system risk (Article 9), and domestic distribution system risk (Article 10). Specifically, WSPs, applied through this framework, include: Risk Identification: Water suppliers carrying out the risk assessment of the supply system  must identify the hazards (biological, chemical, physical, or radiological agents) and hazardous events in the supply system. This assessment must take into consideration risks stemming from climate change, leakages and leaking pipes. The identification also covers specific pollutants relevant for the catchment areas. Risk Assessment, Validation, and Management: Once risks are identified, specific strategies must be implemented to mitigate them. This involves systematically determining the risk score  (product of likelihood and severity) and risk level. For existing measures, this requires validating the effectiveness of existing control measures  in controlling the hazardous event. Based on the outcome, control measures  are defined and implemented for the prevention and mitigation of risks identified in the supply system. This also involves implementing a supply-specific operational monitoring program  (article 13) to ensure control measures function as intended. Emergency Procedures and Corrective Actions : The WSP framework includes developing Emergency Response Plans (ERPs) for serious situations that require immediate, extensive action for which there is no standard operating procedure. In the event of non-compliance with parametric values that constitute a potential danger to human health, immediate remedial action (article 14) must be taken, including prohibiting or restricting the water supply.   This approach not only ensures immediate protection but also contributes to the long-term resilience of drinking water supply systems.   4. Materials in Contact with Drinking Water (Articles 10 and 11) A significant innovation introduced by the directive concerns materials in contact with drinking water. To prevent harmful substances from leaching into drinking water, the directive sets minimum requirements for these materials and establishes a harmonized framework across the EU. On April 23, 2024, the European Commission published a comprehensive set of legal acts in the Official Journal of the European Union, including three implementing decisions (EU 2024/365, EU 2024/367, EU 2024/368) and three delegated regulations (EU 2024/369, EU 2024/370, EU 2024/371). These new measures introduce: A Positive List  of authorized starting substances, compositions, and constituents used in materials that encounter drinking water. Testing Methodologies  and harmonized European Positive Lists to ensure consistent safety evaluations. A Procedure for Adding New Substances  to the Positive List (Regulation (EU) 2024/369). Conformity Assessment Procedures and rules for designating assessment bodies (Regulation (EU) 2024/370). Harmonized Specifications for Product Marking , ensuring transparency and traceability (Regulation (EU) 2024/371). These regulations, which came into force on May 15, 2024, will generally apply from December 31, 2026 . They cover materials used in new installations for water abstraction, treatment, storage, and distribution, as well as those used in repair works. Through these measures, the EU has established a unified, science-based approach to ensuring the safety and quality of drinking water from source to tap, further strengthening public health protection and supporting the free movement of compliant materials and products across the internal market.   5. Consumer Information Access A crucial aspect of this directive is transparency. Consumers must be regularly informed about the quality of the water they consume. The results of water quality analyses should be easily accessible and understandable, such as through mobile apps or water bills. Additionally, water suppliers must inform consumers about corrective measures in the event of contamination, potential health risks, and actions taken to ensure water quality. This transparency aims to build consumer trust in tap water, encouraging its use over bottled water.   Conclusion Directive (EU) 2020/2184 represents a major advancement in ensuring high-quality drinking water across the European Union. It imposes new safety standards, strengthens water quality monitoring, and introduces strict requirements for materials used in drinking water infrastructures. Furthermore, it adopts a risk-based approach in line with the Water Safety Plans (WSPs) , supporting proactive risk management. The emphasis on transparency and consumer trust in tap water is also key. In a future article, we will explore in greater detail the European Positive Lists (EUPL) , which play a crucial role in regulating materials in contact with drinking water. Stay tuned!

Octocrylene is a widely used ultraviolet (UV) filter in cosmetic products, particularly sunscreens, designed to absorb UVB and part of the UVA spectrum, thereby protecting the skin against the harmful effects of sunlight. Currently, octocrylene is authorised in cosmetic products at a maximum concentration of 9% in accordance with Annex VI of the European Cosmetics Regulation [1]. However, due to increasing environmental concerns, and following a proposal from the French Agency for Food, Environmental and Occupational Health & Safety (ANSES), the European Chemicals Agency (ECHA) launched in 2025 a public consultation concerning a potential restriction on the use of octocrylene in finished cosmetic products. This proposed restriction aims to prohibit octocrylene in cosmetic products at concentrations equal to or greater than 0.001% [2]. The public consultation will open on 24 September 2025  and close on 24 March 2026 . Early comments are encouraged before 23 January 2026 , to allow the Committees to consider feedback during their initial discussions. The final decision on this proposed restriction is expected in 2027, following the opinions of ECHA’s scientific committees and the European Commission [2].   1. Rationale for the Restriction The primary objective of this restriction is to mitigate environmental risks arising from the widespread accumulation of octocrylene in aquatic environments. Although octocrylene is an effective UV filter for skin protection, it poses an environmental hazard due to its persistence and toxicity, particularly in aquatic ecosystems. Indeed, octocrylene is poorly biodegradable and may accumulate in the biological tissues of aquatic organisms [1] .   2. Hazard Characterisation The hazard profile of octocrylene is evaluated based on its ecotoxicological properties, including toxicity, persistence, and bioaccumulation potential. • Persistence and limited biodegradability: Octocrylene is concluded to be persistent (P)  and very persistent (vP)  due to its low biodegradability, according to standard OECD 301 biodegradation tests. It displays high lipophilicity (log Kₒw > 6) and an aromatic structure, both indicators of potential bioaccumulation in biological tissues.Although environmental monitoring data suggest in situ accumulation in living organisms, in vivo fish studies  indicate that octocrylene is neither bioaccumulative (B) nor very bioaccumulative (vB)  under the bioaccumulation criteria of Annex XIII of REACH. Consequently, octocrylene is not classified as very persistent and very bioaccumulative (vPvB)  [1]. • Aquatic toxicity: Octocrylene exhibits high chronic toxicity to aquatic organisms. Tests on Daphnia magna  established a NOEC (No Observed Effect Concentration)  of 2.66 µg/L  for reproduction, indicating significant toxicity even at low concentrations. From this, a PNEC (Predicted No Effect Concentration)  of 0.266 µg/L  for freshwater can be derived [1] .   3. Risk Characterisation The environmental risk assessment combines both the hazard profile of octocrylene and the actual exposure conditions in aquatic environments. The risk is expressed as the ratio between the Predicted Environmental Concentration (PEC) and the Predicted No Effect Concentration (PNEC).   Risk Characterisation Ratios (RCR): The RCRs—comparing PEC to PNEC—are used to assess risk under various exposure scenarios. RCR values exceed 1 in most cases. In the scenario related to emissions during bathing in freshwater lakes (ES 12), RCR values are calculated at 744 for freshwater and 7443 for freshwater sediments.For marine coastal waters, the RCR is 109 for water and 1108 for sediments. These values indicate that actual concentrations of octocrylene in the environment far exceed the PNEC of 0.266 µg/L, suggesting an unacceptable environmental risk [1,2]. Emission and dissemination pathways: The main emission routes of octocrylene into the environment include: Direct release during swimming , where up to 50% of the applied amount may be washed off into the water [2]; Indirect release via domestic wastewater , leading to the dissemination of octocrylene into agricultural soils and watercourses, thereby increasing aquatic contamination [1,2]. Such widespread and persistent emissions contribute significantly to aquatic pollution and heighten environmental risk.   4. Proposed Restriction The restriction proposal under public consultation aims to ban the use of octocrylene in finished cosmetic products at concentrations ≥ 0.001% . This measure seeks to reduce emissions of the substance into the environment, mainly by limiting its use in cosmetics, which constitute the primary source of exposure [1,2] .   5. Scientific and Industrial Implications Key strengths of the restriction: Protection of aquatic ecosystems:  Octocrylene is toxic to many aquatic organisms even at low concentrations. Restricting its use would help preserve aquatic ecosystem integrity [1] . Availability of substitutes:  Several next-generation UV filters with more favourable environmental profiles are available as potential alternatives to octocrylene in cosmetic formulations. Precautionary principle:  Reducing exposure to this substance aligns with the REACH Regulation’s objectives to minimise exposure to persistent and toxic chemicals [1] . Limitations and uncertainties: Bioaccumulation uncertainty:  Although persistent, the bioaccumulation potential of octocrylene in aquatic organisms remains insufficiently characterised [1] . Ecological substitutes:  While alternative UV filters exist, their environmental profiles have not yet been fully validated, which may hinder their immediate implementation   [2] .   6. Conclusion Assessments by France and ECHA conclude that the widespread use of octocrylene represents an unacceptable environmental risk under REACH criteria. The key hazard elements, chronic toxicity, persistence, and wide diffusion, justify a preventive regulatory action.The proposed restriction, setting a threshold of 0.001%, represents a strong regulatory measure to protect aquatic ecosystems, while granting industry sufficient time to adapt. Octocrylene exemplifies the balance between environmental protection and human health safety. The European Commission’s final decision will need to ensure a transition towards safe, efficient, and sustainable cosmetic products.   References French Agency for Food, Environmental and Occupational Health & Safety (ANSES).

The unexpected appearance of N-nitrosamine impurities in medicines marked a major regulatory turning point. These compounds, already known to occur in the environment and food, compelled the global pharmaceutical industry to re-evaluate its manufacturing processes. In response, an unprecedented level of international coordination emerged among major regulatory agencies, including the FDA (United States), EMA (Europe), Anvisa (Brazil), and Health Canada, aiming to assess the extent of the issue and establish mitigation strategies. This event had a profound impact on the reassessment of manufacturing processes, enforcing increased vigilance and stricter controls at all stages of pharmaceutical production—from raw materials to finished products. Toxicological Profile of N-Nitrosamines Structure and Mechanism of Action N-nitrosamines are characterized by a nitroso (-N=O) functional group bound to an amine (>NR₂). Their toxicity relies on a crucial bioactivation mechanism that begins with α-hydroxylation, primarily catalyzed by cytochrome P450 (CYP 450) enzymes. This step leads to the formation of unstable intermediates that subsequently generate reactive diazonium ions. These ions are highly electrophilic and can interact with DNA, causing irreversible genetic damage. Mutagenic and Carcinogenic Properties Due to their ability to alter DNA, N-nitrosamines are classified as mutagenic and genotoxic agents. Their properties also make them potent carcinogens. Extensive studies have shown that 82% of 228 tested nitrosamines were carcinogenic in vivo, underlining their hazardous nature. This high prevalence of carcinogenicity justifies the stringent regulatory measures implemented and the need to minimize their presence in pharmaceutical products. The 2018 Crisis and Its Expansion The N-nitrosamine crisis emerged in 2018, following the unexpected detection of N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA) in sartan drugs—commonly used for the treatment of hypertension and heart failure. This initial discovery quickly led to a broader investigation, revealing a more systemic issue. Contamination was subsequently identified in other widely prescribed medicines, including ranitidine (an H2 receptor antagonist), nizatidine (another antiulcer drug), and metformin (used to treat type 2 diabetes). The detection of these impurities resulted in large-scale product recalls worldwide, exposing the systemic nature of the problem and highlighting the need for a comprehensive reassessment of manufacturing and quality control processes within the pharmaceutical industry Sources of N-Nitrosamine Contamination Contamination of pharmaceuticals with N-nitrosamines can arise from multiple sources and complex mechanisms throughout the drug lifecycle. Understanding these origins is essential to prevent and mitigate their formation: Formation during synthesis:  Reaction between nitrites and secondary or tertiary amines (or their precursors) under acidic or high-temperature conditions. Reagents or intermediates may themselves be contaminated. Contaminated solvents:  Certain solvents such as Dimethylformamide (DMF) or N-Methyl-2-pyrrolidone (NMP) may degrade into amines or nitrites, leading to N-nitrosamine formation. Recycled materials:  Use of recycled solvents or reagents, if insufficiently purified, can introduce N-nitrosamines or their precursors. Azide degradation:  Azides used in specific syntheses may degrade in the presence of nitrites to form N-nitrosamines. Excipients:  Some excipients may contain tertiary amines (e.g., crospovidone, povidone) or be contaminated with nitrites, promoting in situ formation of N-nitrosamines in the finished product. Active substance degradation:  The active ingredient itself can degrade to generate amines or other precursors of N-nitrosamines. Packaging materials:  Primary packaging materials (e.g., certain plastic films or labels) may release amines or nitrites that react with the drug product. Storage conditions:  Elevated temperature and humidity during storage can accelerate component degradation and N-nitrosamine formation over time. Regulatory Framework and Mitigation Strategies Given the complexity and scale of the N-nitrosamine issue, regulatory agencies have established a structured three-step approach for the pharmaceutical industry: Risk Assessment: The first step involves identifying potential risks of N-nitrosamine formation or contamination across the entire product portfolio. This requires a detailed analysis of synthesis pathways, raw materials, excipients, solvents, and manufacturing and storage conditions. Manufacturers must demonstrate that they have thoroughly evaluated and characterized these risks. Confirmatory Testing: Following risk assessment, robust analytical testing is required to confirm the presence or absence of N-nitrosamines. High-sensitivity methods, such as liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS), are preferred for their precision and ability to detect trace levels of these impurities. Control and Mitigation: If N-nitrosamines are detected, or a significant risk is identified, control and mitigation strategies must be implemented. These may include modifications to synthesis routes, use of alternative raw materials, optimization of storage conditions, or the establishment of strict impurity limits. Dedicated working groups, such as the NISG (Nitrosamine Impurities Steering Group)  and the NITWG (Nitrosamine Impurities Working Group) , have been created to coordinate actions and share best practices globally. Acceptable Intakes of N-Nitrosamines To protect public health, regulatory authorities have defined Acceptable Intake (AI)  limits for N-nitrosamines. The underlying principle is to ensure that the additional lifetime cancer risk remains below 1 in 100,000. Specific AI limits have been established for the most common N-nitrosamines: NDMA (N-nitrosodimethylamine):  96 ng/day NDEA (N-nitrosodiethylamine):  26.5 ng/day For newly identified nitrosamines lacking compound-specific toxicological data, the Carcinogenic Potency Categorization Approach (CPCA)  is applied. This approach classifies nitrosamines into carcinogenic potency categories (PC 1 to PC 5), each associated with corresponding AI limits. In addition, the Less-Than-Lifetime (LTL)  concept allows temporary adjustment of exposure limits for shorter treatment durations, acknowledging that cumulative risk is lower over limited periods.

When a company develops a new ingredient, whether it is a concentrated plant extract, a biotech-derived ferment, a processed algae or a “functional” mushroom, one recurring question always arises: is a Novel Food procedure required before marketing the ingredient within the EU?   This question often emerges when the project is already well advanced: the formulation is nearly finalized, the marketing identity is ready, the first commercial discussions have started… and suddenly, regulatory uncertainty arises. This can cause a serious slowdown, or even block market entry, if the question has not been addressed early on.  The reality is that innovation does not take place solely in the laboratory or through marketing arguments. An essential part of success lies in the regulatory qualification of the ingredient , particularly regarding its possible classification as a Novel Food  under the criteria defined by the European Union.    What “Novel Food” Really Means  The term Novel Food  does not imply a risk or a restriction. It refers to a regulatory concept : a Novel Food is simply a food or ingredient that was not consumed to a significant degree before 15 May 1997  by the European population, or that results from an innovative process  altering its composition or bioavailability.  Since safety cannot be justified through long-term, significant consumption, it must instead be demonstrated through toxicological safety studies .  Therefore, Novel Food status is not a judgment of immediate safety , but rather an invitation to demonstrate safety  in an official dossier, evaluated by EFSA and validated at the European level. Being classified as Novel Food does not mean “impossible to market”, but rather “requires prior authorization”.    A Quick Test to Know if Your Ingredient Falls Within the Novel Food Scope  Here are a few simple points of attention. If several of these statements apply to your ingredient, a Novel Food status analysis is likely necessary.  Your ingredient has not been the subject of documented consumption in Europe before 1997.   You use an innovative process that modifies the concentration, structure, or metabolites of the raw material.   The ingredient is fermented using a strain or a technique that is not part of Europe’s food tradition.   The source comes from a species rarely consumed in the EU (specific microalga, medicinal mushroom, microorganism, cell culture, etc.).   The final chemical profile is no longer comparable to the traditional raw material.  If you identify with one or more  of these cases, a regulatory screening  is recommended before any commercial communication or product launch.    Common, and Often Underestimated, Situations  Many companies believe they fall outside the scope of the Novel Food Regulation because the ingredient exists naturally or is consumed in other parts of the world. However, the reality is quite different.  example, while curcuminoids extracted from Curcuma longa  root  and standardized to 95% curcumin are authorized in Europe for use in food supplements, curcumin itself  is considered a Novel Food.    Regulatory Solutions to Confirm the Status of Your Ingredient  The Novel Food Regulation allows, in cases where an ingredient’s status is unclear, to consult the competent authorities  through a formal consultation procedure  designed to officially determine the status of an ingredient.  This procedure gives an EU Member State the responsibility, based on data provided by the applicant, to decide on the ingredient’s classification. It is an optional procedure , with both advantages and disadvantages  that should be carefully assessed before submission.    What Changes When an Ingredient Is a Novel Food  When an ingredient is considered a Novel Food, the regulatory approach changes. It is no longer simply a matter of verifying compliance with a positive list, but of providing scientific evidence of safety  for European consumers under realistic conditions of use (dose, formulation, target population, cumulative exposure, etc.).  The evaluation covers:  The exact composition, including impurities, possible nanoparticles, solvents, or residues  Technical specifications (natural variability, stability)  Manufacturing processes  Dietary exposure of different population groups  Available toxicological data  The ability to demonstrate absence of risk under intended conditions of use    The Importance of Anticipation  The earlier the status is assessed, the more secure the time-to-market  will be. Conversely, discovering a potential Novel Food issue once formulations are finalized and commercial partners are engaged can lead to multi-year delays,  time needed to compile a dossier, conduct or gather the required studies, submit to the competent authorities, and wait for their evaluation.  This is why more and more companies are integrating a Novel Food regulatory screening  early in the development phase, even before finalizing the product positioning.    CEHTRA, Supporting You to Decide Quickly and Wisely  At CEHTRA , we support project leaders, manufacturers, and start-ups during this critical qualification phase. The goal is not only to prepare a dossier later, but to help you make the right decisions quickly :  Verify whether the ingredient falls under the scope of the Novel Food Regulation  Identify the elements to be documented (consumption history, equivalence, composition, etc.)  Build a realistic and progressive safety assessment strategy  Develop a clear, well-argued, and robust dossier in case of official submission  Our approach aims to secure your innovation without unnecessary obstacles .    In Conclusion  Determining whether an ingredient is a Novel Food is not a mere administrative formality, it is a strategic step  that defines commercial feasibility, cost anticipation, and credibility with partners.  The earlier the verification is carried out, the smoother, more controlled, and transparent the innovation path will be, both internally and with investors, clients, and distributors.  To discuss your specific case or request a Novel Food status assessment, you can contact Marie Liamin , Food Products Market Manager at CEHTRA .

The identification of endocrine disruptors (EDs) has become a major public health and environmental concern worldwide. EDs are chemical substances capable of interfering with the hormonal system, leading to adverse effects on both humans and wildlife. Monitoring and assessing these substances is essential to protect human health, particularly among vulnerable populations such as pregnant women, children, and wild species. To this end, the U.S. Environmental Protection Agency (EPA) has developed ToxCast , a comprehensive database compiling in vitro  biological activity data for hundreds of chemicals, enabling the analysis of their potential endocrine-disrupting effects. What is the ToxCast Database? ToxCast  (short for Toxicity Forecaster ) is a flagship EPA program designed to evaluate the toxicological potential of chemicals. Using a suite of high-throughput in vitro screening (HTS)  assays, ToxCast examines the bioactivity of thousands of chemicals across multiple biological targets. These in vitro  assays measure biological responses, including hormonal activity, on specific receptors, enzymes, and cellular processes involved in endocrine regulation. The main goal of ToxCast is to provide detailed data on chemical substances to predict their potential to interfere with biological systems, particularly endocrine systems in humans and animals. With data on more than 10,000 chemicals , ToxCast has become an invaluable resource for researchers and regulators seeking to identify endocrine disruptors. One of the key advantages of ToxCast lies in its non-animal testing approach , reducing reliance on traditional animal studies. This aligns with the European Union’s “One Health” strategy , Directive 2010/63/EU, and the EU roadmap toward phasing out animal testing, by promoting the use of alternative methods such as in vitro  assays and computational approaches in toxicity assessment. What Does This Update Include? The latest version of the ToxCast database, invitrodb v4.3 , introduces several critical improvements, many of which directly enhance its usefulness in endocrine disruptor evaluation. 1. Enhanced Data Analysis The updated ToxCast release introduces new analytical features that improve the accuracy and reliability of in vitro  screening data interpretation. These enhancements allow researchers to better understand biological effects on hormone receptors and other key mechanisms underlying endocrine function. Improved analytical tools now integrate additional parameters, making it easier to compare data across substances. For example, chemical effects on hormonal receptors can be assessed faster and more precisely, allowing for early detection of substances potentially disrupting endocrine pathways . 2. Updated Software Tools The software tools used to process ToxCast data have also been upgraded. Widely used R packages , such as tcpl and tcplFit2, have been enhanced to provide improved data handling, smoother workflow management, and more advanced visualization capabilities. The tcplFit2 package, for instance, now offers more accurate dose–response curve fitting , enabling more reliable estimation of effect concentrations. This is essential for assessing risks associated with low-dose exposures to EDs, which are frequently encountered in real-world environmental settings. 3. Expanded Chemical Coverage The update also expands ToxCast’s chemical coverage, now encompassing over 10,000 evaluated substances . This broader dataset supports a more comprehensive toxicological assessment, including for lesser-known or emerging substances that may pose endocrine-related risks. CEHTRA’s Digital Tool: Supporting ED Identification One of the major advances in applying ToxCast data is CEHTRA’s digital tool , designed to facilitate rapid access and interpretation of information from the ToxCast database. 1. Instant Substance Check Through a CAS number search , CEHTRA’s tool allows instant verification of a chemical’s regulatory status and its inclusion in lists of potential or confirmed endocrine disruptors. By entering a single CAS number, users can access detailed information about a substance’s status, potential toxicity, and regulatory evaluation history. This feature represents a significant time-saver , offering quick and reliable access to critical regulatory and toxicological data. 2. Integrated ToxCast Data Analysis Beyond regulatory status, the CEHTRA tool also enables direct analysis of ToxCast data  for the queried substances. It streamlines the exploration of in vitro  high-throughput screening results to assess bioactivity on endocrine-relevant biological targets. In just a few clicks, users can visualize the full spectrum of a substance’s biological effects on hormone receptors, enzymes, and related cellular pathways. By simplifying the use of complex datasets, CEHTRA’s tool empowers users to draw scientifically robust conclusions on endocrine activity , supporting both regulatory assessments and research efforts. This functionality is particularly valuable for ED studies, where data heterogeneity often poses analytical challenges. Conclusion The latest ToxCast database update  marks a major step forward in the evaluation of endocrine disruptors. With expanded chemical coverage, improved analytical methods, and enhanced data management, this update provides a stronger foundation for assessing the potential hazards of chemical substances. CEHTRA’s digital tool complements this progress by offering an intuitive platform to access and analyze ToxCast data efficiently. Together, these innovations enable faster, more reliable identification of endocrine-disrupting substances, strengthening the capacity of regulatory and industrial stakeholders to protect public health and the environment .

PFAS at the Heart of Regulatory Concerns Per- and polyfluoroalkyl substances (PFAS) are receiving increasing attention from European authorities due to their persistence, bioaccumulation, and toxicity. In this context, the Plant Protection Products (PPP)  sector is now under closer scrutiny following the publication of the ECHA Annex XV restriction report . According to this report, active substances used in PPPs, biocidal products, and medicinal products differ chemically from other PFAS subgroups  due to the presence of one or more CF₃ groups , a key molecular signature for understanding their environmental behavior . Key Figures from ECHA and the EU Pesticide Database While the PPP sector represents only 2% of total PFAS sales  within the EU, it remains a major regulatory focus . Based on data from the European Pesticide Database , 89 molecules  contain at least one CF₃ group: 57  have already expired and are no longer in use 1  is currently under evaluation for first approval 25  are undergoing renewal procedures 6  are scheduled for future renewal In addition, Annex A (v2 – 2023)  lists 47 PFAS-based active substances  used in PPPs (non-exhaustive list), all requiring further assessment and regular updates . Trifluoroacetic Acid (TFA): A Key Regulatory Issue Trifluoroacetic acid (TFA)  can form in soil, water, and plants from the degradation of molecules containing CF₃ groups. Persistent and toxicologically relevant, TFA has now come under close examination by European authorities. Some active substances in PPPs degrade into TFA, potentially impacting renewal timelines or leading to stricter re-evaluations. What to Expect in 2025: EFSA Task Force Dedicated to TFA The European Food Safety Authority (EFSA) has established a dedicated working group to revise the toxicological reference values for TFA. Two initial meetings took place in November 2024 and February 2025, focusing on: Reviewing TFA data submitted by EU notifiers (in vivo and in vitro studies) Proposing updated reference values Coordinating with ECHA’s Risk Assessment Committee (RAC) and the German competent authority Additional meetings are planned throughout 2025, with an official EFSA statement expected by year-end, which could reshape evaluation and renewal strategies across the sector.

n-Hexane (CAS No. 110-54-3) is a volatile aliphatic hydrocarbon derived from petroleum distillation. Used as a solvent, it plays a key role in several sectors:  Food industry : extraction of vegetable oils (soy, rapeseed, sunflower), flavors, and proteins.  Cosmetics and perfumery : obtaining absolutes, essential oils, and pure plant extracts.  Its popularity is based on its efficiency, high yield, and low cost. However, this solvent requires strict purification to limit residues and protect exposed workers ( ANSES ).   Long largely unknown to the general public, its use is now attracting attention. The press ( Le Point ) recently highlighted that it could indirectly be present in certain food products. Once metabolized, n-hexane is converted into 2,5-hexanedione, a molecule capable of accumulating in the brain and causing neurological effects ( Fiche toxicologique n°113 - Edition Juin 2025).    The ECHA Proposal: Toward Inclusion on the SVHC List  In February 2025, Slovenia proposed to ECHA (European Chemicals Agency) that n-hexane be classified as a Substance of Very High Concern (SVHC) due to its neurotoxicity. The public consultation, opened in August 2025, will close on October 16, 2025.  This classification is based on Article 57(f) of the REACH Regulation (EC No. 1907/2006). The candidate SVHC list already includes over 240 concerning substances (carcinogens, reproductive toxins, endocrine disruptors, etc.). Inclusion triggers information obligations and can lead to authorizations or usage restrictions.    Implications for the Cosmetic and Food Industries, and for Consumers  Transparency and labeling: obligation to inform when a product contains more than 0.1%.  Search for alternatives : adoption of safer processes (supercritical CO₂, “green” solvents).  Costs and reformulations : adaptation of processes, investments, and potential increase in final product price.  Health and public perception : better protection and transparency for consumers, but possible increased concern reported by media.  Regulatory pressure and certifications : organic certifications and certain markets will likely require its absence, accelerating the transition to other techniques.  This trend is already encouraging the development of solvent-free processes, such as the EcoXtract®  approach.    Consideration in Cosmetic Products  In cosmetics, n-hexane may remain as trace  residues after ingredient extraction. At these levels, the risks are considered negligible for consumers. European Cosmetic Regulation No. 1223/2009 requires safety assessors to check for these impurities in their reports.    Classified as CMR (Repro cat.2, H361f) , n-hexane is prohibited as an ingredient  in cosmetic products. As in the pharmaceutical sector (ICH Q3C (R8)), it is only tolerated as a residual impurity  at strictly limited concentrations. Its neurotoxic effects, severe at high doses, are known and controlled through exposure thresholds. Therefore, the presence of traces does not pose a danger to the end user.    Ensuring Safety and Anticipating Regulatory Changes  For manufacturers, having a detailed toxicological profile  of each substance is essential to secure formulations and anticipate regulatory developments. Potential inclusion of n-hexane on the SVHC list would mark an important step and could accelerate the transition to more sustainable alternatives.  In the context of cosmetic regulations, having a detailed toxicological profile helps professionals anticipate and secure their formulations.  ➡️ To explore the complete profile of this substance, visit our dedicated page: 👉  https://www.cehtra.com/cosmetick    And check out the associated LinkedIn post  for a concise overview.

A Floral Aldehyde Under Regulatory Scrutiny HOMONOPAL, also known as Pinoacetaldehyde, is a synthetic aromatic aldehyde commonly used in fragrance compositions. Its CAS number is 33885-51-7. Known for its green, floral, and slightly aldehydic scent, this compound imparts freshness and lift to perfume accords, particularly in fine fragrances, personal care products, and cleaning formulations. Industries Impacted HOMONOPAL is used across a wide range of sectors: Cosmetics and personal care, including perfumes, shampoos, lotions Household cleaning agents Industrial fragrance applications Its broad application stems from both its olfactory profile and its performance in complex fragrance matrices. New Regulatory Developments from ECHA In April 2025, the European Chemicals Agency (ECHA) published a new Assessment of Regulatory Needs  (ARN)  for Pinoacetaldehyde. This document significantly shifts the regulatory landscape for this fragrance ingredient, highlighting serious human health and environmental concerns. ECHA concludes the substance presents: Known or potential hazard for reproductive toxicity Known or potential hazard for skin sensitisation Known or potential hazard for aquatic toxicity Based on this assessment, ECHA outlines the following regulatory actions: "Harmonised classification as Reprotoxic category 1B." "Potential restriction: Harmonised classification as Repr. 1B would lead to generic restriction of the substance(s) in consumer mixtures by means of restriction entry 30." "The harmonised classification as Repr. 1B may trigger regulatory action under the Cosmetic Products Regulation and render the substance unacceptable as a co-formulant in biocidal products." The assessment also notes that HOMONOPAL is widely used in professional settings, often with low levels of operational controls and risk management: “Restriction of professional uses is preferred over authorisation as it is considered to be more efficient and effective to introduce controls at the level of placing on the market rather than at the level of uses.” "Frequent exposures with a long duration" are also highlighted, particularly concerning for vulnerable worker populations. Implications for the Cosmetics Industry The harmonised classification as Reprotoxic Category 1B  has direct implications for cosmetic uses. Under the Cosmetic Products Regulation (EC) No 1223/2009, substances classified as Repr. 1B are generally prohibited unless explicitly exempted by the European Commission. In practical terms, this could mean: Prohibition of HOMONOPAL in consumer cosmetics Reformulation pressures on fragrance suppliers Loss of functionality in certain perfume accords If the restriction under Annex XVII, entry 30 of REACH is adopted, it will also mean a generic restriction in consumer mixtures, including many non-cosmetic fragrance applications. Conclusion The regulatory future of HOMONOPAL is now at a critical juncture. While still legally used today, the proposed harmonised classification and restrictions may lead to its complete phase-out in consumer products, including cosmetics. Formulators, regulatory teams, and risk assessors should begin preparing substitution strategies and consider the toxicological profile of alternatives. This case exemplifies the increasing scrutiny on fragrance ingredients and the importance of proactively managing substances with potential reproductive and environmental hazards.

When it comes to nutrition, dietary supplements, or innovative ingredients, the word “ natural ”  immediately inspires trust. But is a natural ingredient always safe for consumption? Spoiler alert : not necessarily. And this is precisely what scientists and food safety experts strive to demonstrate—with evidence to back it up. Natural does not mean harmless The misconception is persistent: what comes from nature cannot cause harm. Yet nature is full of active, powerful substances… sometimes toxic. Some well-known examples include: Certain plants, such as belladonna or foxglove, can cause severe poisoning. Essential oils, which are very popular, may contain molecules with neurotoxic or irritating effects that can present a risk if not used appropriately. Beyond the intrinsic composition of natural products, external contamination (heavy metals, hydrocarbons, bacterial toxins, microbes…) can also render natural substances unfit for consumption. In short: natural ≠ harmless. And this is something that national health authorities and EFSA (European Food Safety Authority) regularly remind us of through their scientific evaluation What determines the safety of a natural ingredient The safety assessment of an ingredient derived from natural products does not depend solely on its origin. It is based on several factors, including: Chemical composition : extraction, concentration, presence of secondary metabolites… Parts used : composition can vary greatly between a plant’s root, leaves, or fruit. Dose of exposure : “the dose makes the poison,” as Paracelsus once said. Mode of consumption : ingestion, skin application, inhalation… Consumer profile : healthy adult? pregnant woman? child? A plant extract used for centuries in herbal tea can become problematic if concentrated in a dietary supplement or given to a vulnerable population. An essential safety evaluation In Europe, food ingredients without a significant history of consumption prior to 15 May 1997 are considered Novel Food . This means they must undergo an authorization request to the European Commission. The aim of this request is to demonstrate the safety of the Novel Food under the intended conditions of use. These often complex dossiers must provide scientific evidence, frequently supported by toxicological data, of their safety. Even outside the Novel Food framework, all food products, including those already authorized, must be free of risk for consumers. It is the responsibility of manufacturers and/or market operators to ensure this absence of risk, by keeping up to date with regulatory and toxicological developments concerning the ingredients they use. CEHTRA supports you in securing your natural ingredients At CEHTRA, we support industries, start-ups, and project leaders through these complex steps of assessing the safety of their products. We offer: Analysis of available toxicological data on your product ingredients Identification of regulatory status (Novel Food or not) Preparation of a solid safety dossier Integration of digital tools to anticipate potential issues Our specialized team helps you secure innovation without slowing down your ambitions.

1. Known Uses  Glabridine is an isoflavonoid (isoflavane) extracted from Glycyrrhiza glabra  (licorice root). It is widely used in cosmetics for its skin-lightening and anti-tyrosinase activity, as well as for its antioxidant and anti-inflammatory properties. It is mainly found in skincare products, anti-aging creams, and sunscreens. 📖 J Lui, 2025 ScienceDirect   2. Mechanism of Action of Glabridine   Glabridine inhibits tyrosinase, a key enzyme in melanin synthesis responsible for skin pigmentation. It acts as a reversible, non-competitive inhibitor, meaning it effectively reduces tyrosinase activity without directly binding to its active site. This inhibition occurs through a multi-phase kinetic process, suggesting the formation of a stable glabridine-tyrosinase complex. 📖 J Chen, 2016 PubMed   3. Toxicological and Regulatory Concerns   Available scientific data show efficacy in tyrosinase inhibition, but systemic toxicity studies remain limited. Points of caution include:  The potential estrogenic activity of certain isoflavones, an endocrine-disrupting effect observed in some tests, particularly in vitro, cannot be excluded (CIR Glycyrrhiza Glabra  (Licorice), 2008) CIR Reports   Limited data on systemic toxicity and reproductive toxicity (EFSA, 2011) EFSA Journal   Our view:  Such effects and “data gaps” warrant further research.  In the context of cosmetic regulations, having a detailed toxicological profile helps professionals anticipate and secure their formulations.  To explore the complete profile of glabridine, visit our dedicated page:  https://www.cehtra.com/cosmetick    📢 And check out the associated LinkedIn post for a concise overview : https://lnkd.in/p/eSj7GxE5

In the recent meeting of Coordination Group (CG-54), a proposal of the Austrian Member State was discussed which has been raised in a CG e-consultation, concerning information on the use frequency of products (“Number and timing of application”) for use in PT 1, PT2 and PT4 given by the applicants in SPC and PAR for BPR product authorization. Austrian authorities are experiencing that applicants often use quite general terms for application frequency for professional and nonprofessional use, such as “as required” or “daily use”, etc. It has been proposed that these general terms must not be accepted any longer by the Member States, as the application frequency, e.g., expressed in number of applications per day, determines how often the product is applied and is a crucial input parameter especially for human exposure assessment. The maximum or typical number of applications per day must be stated in SPC and DRA/PAR authorised use to reflect realistic worst-case assumptions. This proposal has been agreed at CG-54 meeting in November 2022 by consensus: For product authorisation, the use frequency must be given in SPC and PAR according to the guidance and Annex VI, point (33) of the BPR and the term ‘as required’ (or similar terms, e.g. ‘daily use’) for determination of application frequency shall be no more accepted by the member states for the application frequency without further justification. Details of application frequency are relevant input parameters for human and environmental exposure and risk assessment. Therefore, the (maximum or typical) number of applications per day must be stated in SPC and DRA/PAR authorised use. Examples are given as follows: Example 1 , hand disinfectants used in the medical sector: Nurses or hospital/medical staff should use hand disinfectants as often as necessary. However, in the case of hand disinfectants, a “maximal or typical” number of applications per day should be indicated in SPC and PAR authorised uses. This number should correspond to the safe number of applications determined by the exposure scenario (reverse reference scenario). Example 2 , surface disinfection products: no clear use frequency can be set. Therefore, a “maximal or typical” number of applications per day should be indicated in SPC and PAR authorised uses. This number should correspond to the safe number of applications determined by the exposure scenario ( reverse reference scenario , chapter 3.2.5.5). Example 3 , automated dosing: In certain situations, “as required” can mean “adding the product intermittently to the system, in order to maintain a system concentration within certain defined limits”. In such cases, the term “as required” might be acceptable. However, typical and/or maximal amount of product needed for application should be given. This conclusion might generally be applied to all PTs.
