Function in Oxidative Hair Color Systems
Bis Aminopropyl Diglycol Dimaleate functions as a key coupler component in oxidative hair dye formulations. It reacts with primary intermediates (such as p-phenylenediamine) in the presence of an oxidizing agent to produce stable, vibrant color molecules within the hair cortex. Its unique diglycol dimaleate structure provides excellent color deposition, wash fastness, and reduced skin sensitization potential compared to conventional couplers.
