chem-data European chemical and regulatory registry

EU chemical database

SVHC, SCIP, REACH, POPs, and source-backed chemical pages.

chem-data is a searchable chemical and regulatory database focused on EU substance status, Candidate List substances, SCIP-relevant screening, REACH authorisation, POPs Regulation context, and official-source provenance.

Most-used topic

SVHC and Candidate List hub

This is the strongest regulatory-intent route so far, so make it the default click for watchlist questions.

 Operational route

SCIP and article-screening guide

Use this when the user question is already downstream of Candidate List status and moving into product workflows.

SVHC and Candidate List hub

 Operational route

SCIP and article-screening guide

Use this when the user question is already downstream of Candidate List status and moving into product workflows.

 Explainer route

POPs meaning and regulated substances

The full-term POPs explainer is already getting attention and deserves a direct top-level path.

 Compound route

n-hexane dossier

This dossier is already showing stronger engagement than the average chemical page and should be easy to reach from home.

Choose the search path that matches your query

Chemical lookup

Search the chemical database

Start with CAS, EC, formula, or a substance name when you need the canonical dossier and status routes first.

 SVHC hub

Browse the SVHC list

Use this when the query is Candidate List substances, substances of very high concern, or ECHA SVHC list status.

 SCIP guide

Understand SCIP database duties

Use this when the question is article communication, SCIP reporting, or Candidate List obligations in products.

 REACH hub

Check Annex XIV substances

Use Annex XIV and REACH authorisation routes when the real question is continued use, authorisation, and sunset-date logic.

 POPs hub

Review persistent organic pollutants

Use this route for persistent organic pollutant definitions, examples, POPs restrictions, and exemption-sensitive reviews.

 Source-backed

Audit official sources

Use source and change pages when you want to know where a claim came from, what changed, and which authority published it.
