About 6-AMINO-M-CRESOL
An oxidative hair-dye coupler. Permitted in EU hair colour at a capped concentration with mandatory allergy warnings — not something you want on unhealthy skin.
Detailed Analysis
6-Amino-m-cresol (CAS 2835-98-5) is an aminophenol used as a coupler in oxidative hair dyes, reacting with para-substituted primary intermediates to yield blonde-to-brown shades. It is regulated under EU Cosmetics Regulation Annex III entry 281 as permitted only in oxidative hair-dye products at a maximum concentration of 1.5% in the mixture ready for application, with mandatory warning statements about hair-dye allergy. It is not permitted for eyebrow/eyelash dyeing. Aromatic amines of this family are recognised contact sensitizers, and the SCCS has issued favourable but conditional safety opinions requiring the Annex III restrictions. Consumers with a history of hair-dye allergy (or prior henna with PPD) should avoid.
