Detailed Analysis
4-Aminoazobenzene (para-aminoazobenzene) is an azo dye that has been prohibited from cosmetic use under EU Regulation 1223/2009 Annex II due to its carcinogenic potential. Azo dyes can undergo reductive cleavage in vivo or under certain environmental conditions, releasing aromatic amines, some of which are known carcinogens. The aminoazobenzene structure itself has demonstrated genotoxic and carcinogenic effects in toxicological studies, making it unsuitable for any cosmetic application.
Known Concerns
