Frequently asked questions

No. ChemVigil is an analytical firm. We evaluate existing published and licensed data, apply read-across where appropriate, and where the evidence is still insufficient, we identify precisely where new testing would add value.

Evaluating existing studies is the foundation of most regulatory hazard assessments, including those conducted by ECHA and the US EPA. Reliability depends on comprehensive coverage and transparent reasoning, the two principles at the core of our methodology.

Send us the substance name or CAS number, the question you need answered, the markets involved, and your deadline, using the contact form or by email. We respond within one business day with a proposed scope, a fixed fee, and a committed delivery date. Work begins as soon as you approve the proposal and, where required, the NDA is in place.

We apply read-across: data from structurally and mechanistically similar substances (analogues or chemical categories) is used to fill specific data gaps, following ECHA's Read-Across Assessment Framework and OECD guidance on grouping of chemicals. Every read-across is documented with its scientific justification and an explicit statement of uncertainty, so you and any reviewer can judge its strength. Where no suitable analogue exists, we say so and identify where new data would be needed.

Our reports are designed to inform compliance decisions and documentation. Formal submissions may require sign-off by a qualified expert in the relevant jurisdiction, and we'll advise you on exactly what is required.

Reports are delivered as PDF documents with an executive summary, endpoint-by-endpoint findings, and a complete source register. Status matrices and source registers can also be provided as spreadsheets on request. Every delivery includes a briefing call to walk through the findings.

We sign NDAs as standard, handle client data securely, and never disclose client identities or product details.
