About
A confirmed human carcinogen (beta-naphthylamine) historically linked to bladder cancer, absolutely banned from cosmetic products in all jurisdictions.
2-Naphthylamine (beta-naphthylamine) is a confirmed human carcinogen that was historically used in the dye industry before its severe toxicity was fully understood. It is listed in EU Annex II as a prohibited substance and is regulated as a carcinogen category 1A substance under CLP Regulation. No CAS number is listed because specific naphthylamine salts may have individual identifiers, but all are collectively banned in cosmetic products under Regulation (EC) No 1223/2009.
