2,6-DIMETHYL-P-PHENYLENEDIAMINE HCL

Description

2,6-Dimethyl-p-phenylenediamine HCl is a potent oxidative hair dye ingredient widely used in the cosmetic industry. This synthetic compound belongs to the family of aromatic amines and plays a crucial role in permanent hair coloration processes. Its chemical structure consists of a para-phenylenediamine core with two methyl groups attached at the 2 and 6 positions, forming a hydrochloride salt.

This ingredient functions as a primary intermediate in hair dye formulations, reacting with oxidizing agents and couplers to produce vibrant, long-lasting color molecules within the hair shaft. It is particularly effective in creating warm brown to black shades and enhancing gray coverage. The presence of methyl groups increases its stability and reduces potential skin sensitization compared to unsubstituted p-phenylenediamine.

When used in hair dye products, 2,6-Dimethyl-p-phenylenediamine HCl typically comprises 0.1% to 3% of the formulation. It is essential to note that this ingredient should only be used in professional settings or in at-home hair dye kits with proper instructions, as it can cause allergic reactions in sensitive individuals. Patch testing is strongly recommended before application to minimize the risk of adverse effects.
