Description
3-Aminophenol (CAS 591-27-5) is an aromatic amine-phenol compound sold under trade names including Furro EG, Fourrine EG, Fourrine 65, and Fouramine EG, with the colorant index designation C.I. 76545. It carries no assigned E-code and is classified under HS code 29222900.
In oxidative hair dye formulations, 3-Aminophenol acts as a coupler, reacting with primary intermediates under alkaline conditions to produce brown and auburn shades through oxidative coupling. In textile and leather processing, it functions as a crosslinking agent, forming covalent bonds with substrate polymers to improve dye fixation and surface durability.
Supplied as a crystalline powder, 3-Aminophenol is available in technical and cosmetic grades compliant with REACH registration requirements. Procurement quantities typically range from kilogram laboratory packs to multi-tonne bulk orders. Buyers should confirm grade specification against relevant regional cosmetic regulations prior to formulation use.
