Is this chemical listed?
Search every compound in the Bedroom Chemistry Atlas against California Proposition 65 and the EU REACH SVHC Candidate List. Free, sourced, and honest about what a listing does and does not mean.
What a listing actually means
California Proposition 65. The state has listed the substance as known to cause cancer, reproductive harm, or both. Listing triggers warning requirements above defined levels. It is a disclosure law, not a prohibition.
EU REACH SVHC Candidate List. The substance has been formally identified as a substance of very high concern. This is not a ban. It triggers notification to ECHA and Article 33 communication down the supply chain when an article contains the substance above 0.1% by weight. Prohibition requires the Authorisation List (Annex XIV) or an Annex XVII restriction, neither of which this tool covers.
EU REACH Annex XVII. A restriction. This is a real legal limit, but it is almost always use-conditional: it restricts specified applications at specified concentrations rather than banning the substance outright. The conditions live in ECHA's own document, linked per entry, and we do not paraphrase the legal text.
EU REACH Annex XIV. The Authorisation List, and the closest thing to a ban in EU chemicals law. After a substance's sunset date, it may not be used or placed on the EU market unless a specific authorisation has been granted for that use. Authorisations do exist, so "banned" still overstates it, but the burden has flipped.
Not listed is not a clean bill of health. It means these two lists do not name the compound. Other jurisdictions exist, other instruments exist, and plenty of substances are unlisted because nobody has assessed them rather than because they were assessed and cleared.
Scope, and where the data comes from
Proposition 65 status comes from California OEHHA. The three EU instruments come from ECHA's own CSV exports of the Candidate List, the Annex XVII restriction list and the Annex XIV Authorisation List. All are joined to our compound Atlas on CAS number, and every compound links through to its Atlas entry with the full source list.
We cover these instruments because they are the ones we can source completely and keep current. Adding one we could only cover partially would make this tool look more authoritative than it is. ECHA maintains the Candidate List in its present form only until December 2026, after which it moves to ECHA CHEM.

Frequently asked questions
Does an SVHC listing mean the chemical is banned in the EU?
No. Candidate List inclusion is a formal identification as a substance of very high concern. It triggers REACH notification and Article 33 supply-chain communication when an article contains the substance above 0.1% by weight. A ban requires entry to the Authorisation List (Annex XIV) or an Annex XVII restriction, which this tool does not cover.
If a compound is not listed, is it safe?
No. Not listed means these two lists do not name it. Other jurisdictions and other regulatory instruments exist, and absence from a list is not evidence of absence of hazard. It may also simply mean the compound has not been assessed.
Why only two jurisdictions?
Because these are the two we can source completely and keep current. California Proposition 65 comes from OEHHA; the SVHC Candidate List from ECHA's own CSV export. Adding a jurisdiction we could only cover partially would make the tool look more authoritative than it is.
How current is this?
The index is built from Embr Exposure Ledger 1.2, built 2026-07-19. ECHA maintains the Candidate List in its present form only until December 2026, after which it moves to ECHA CHEM.
