Regulatory and toxicological monitoring: why too much information kills information

Information overload: a major challenge for chemical regulatory monitoring
In today’s organisations, ensuring effective regulatory and toxicological monitoring of chemical substances has become a major challenge for regulatory teams, toxicologists, and R&D departments.
Depending on markets, companies must track:
sector-specific regulations (cosmetics, biocides, food…)
cross-cutting frameworks (CLP, REACH, SVHC, restrictions, authorisations…)
and external sources such as California Proposition 65, IARC classifications, inventories, and NGO lists
Access to information is no longer the issue. Newsletters, databases, and professional associations continuously provide regulatory news and scientific updates.
→ The real challenge is now information overload.
Regulatory professionals: managing large substance portfolios
Regulatory professionals are responsible for monitoring the regulatory status of hundreds or even thousands of substances.
This involves:
product-level checks
substance-level monitoring
and transversal topics (PFAS, microplastics, CMRs, nanomaterials…)
These activities often represent several days of work each month.
Once the information is collected and filtered, teams still need to:
assess impacts
prioritise actions
ensure compliance
→ But a key question remains:
Can they be sure they are not missing a critical regulatory update? Or, conversely, spending time on information with no real impact?
Toxicologists: between scientific monitoring and regulatory impact
Toxicologists must maintain up-to-date toxicological risk assessments by continuously integrating new scientific data.
They monitor:
scientific opinions (EFSA, US EPA…)
IARC monographs
NTP and RIFM reports
classification intentions (CLH, SVHC…)
→ The challenge is twofold:
identifying relevant toxicological data
without spending time on non-impactful information
Some updates are minor. Others can significantly impact safety assessments and business decisions.
→ The key difficulty is to distinguish critical signals from background noise.
R&D teams: anticipating without clear visibility
R&D teams are directly impacted by this uncertainty.
Internal “blacklists” of substances are sometimes implemented, but they quickly become outdated as scientific and regulatory knowledge evolves.
→ Key questions arise:
Are these lists sufficient?
Should certain substances be avoided proactively?
How early should risks be anticipated?
Without structured monitoring, decisions are made with uncertainty, potentially leading to late or costly reformulations.
The real issue: non-targeted monitoring
The problem is not a lack of information. → It is an excess of non-targeted information.
Teams are forced to analyse data:
unrelated to their substances
without prioritisation
without efficient filtering
→ The key question becomes: “Does this information actually concern my substances?”
Without filtering based on substance portfolios and relevant regulatory and toxicological sources, monitoring becomes:
time-consuming
inefficient
difficult to exploit
The consequences of inefficient monitoring
Poorly structured regulatory monitoring leads to:
significant time loss
difficulty prioritising actions
delayed responses to regulatory changes
→ In the long term, this results in:
operational stress
reduced confidence in monitoring processes
less secure decision-making
Moving towards portfolio-focused regulatory intelligence
To improve monitoring efficiency, two parameters must be clearly defined:
the substance portfolio to monitor
the relevant regulatory and toxicological sources
→ Combining these two dimensions enables:
filtering out irrelevant information
quickly identifying impactful changes
significantly reducing information overload
A structured approach to regulatory and toxicological monitoring
portfolio-based monitoring approach allows organisations to:
identify relevant regulatory and toxicological updates
prioritise actions effectively
optimise internal resources
→ This frees up time for what matters most: impact analysis and decision-making.
In this context, digital tools such as CEHTRA WATCH support this approach by structuring regulatory intelligence, while remaining complementary to expert assessment.
