Product overview & key benefits
In oxidative hair dyes, couplers react with primary intermediates such as p-phenylenediamine after oxidation to build the final color inside the hair. 5-Amino-6-chloro-o-cresol is a coupler used to shape red, violet and brown shades.
Its use in cosmetics is regulated: in the EU it is listed in Annex III of the Cosmetics Regulation with a maximum on-head concentration, and other markets set their own limits. Formulators should confirm the rules in their market. Appearance and melting point below come from this product’s data.
