Disclaimer

This tool is not legal advice. Nothing on this site creates an attorney–client relationship.

What this tool is

An advisory aid that compares the ingredient list you provide against the OEHHA Proposition 65 chemical list and known case law (TiO2 cosmetic injunction, retinol exposure exemption, etc.). It surfaces likely warning requirements and explains the reasoning behind each call.

What this tool is not

• Not a substitute for laboratory testing. Prop 65 enforcement turns on actual chemical concentrations measured in finished product; this tool only reads the ingredient list you provide.
• Not legal counsel. If you receive a 60-day notice, retain a licensed California attorney who handles Prop 65 matters.
• Not a promise of compliance. A no-warning result is a reasoned starting point, not a defense against an enforcement action.
• Not a multi-state compliance tool. California Proposition 65 only. Washington TFCA, AB 1817 PFAS textiles, and other state laws are out of scope.

Accuracy

Tested at 89% F1 / 100% precision on a 100-SKU labeled benchmark. Recall varies by category: cosmetics + supplements + candles clear the 80% bar; apparel is weaker due to incomplete PFAS coverage in the OEHHA list. You should not treat any single result as dispositive.

No warranty

The tool is provided "as is". No warranty of fitness for a particular purpose. We make no representation that a no-warning result will hold up against an enforcement action.
