N,N-DIETHYL-M-AMINOPHENOL SULFATE

About N,N-DIETHYL-M-AMINOPHENOL SULFATE

The sulfate salt of a diethylaminophenol hair dye intermediate, restricted under EU Regulation II/1223 with the same sensitization and concentration concerns as the parent compound.

Detailed Analysis

N,N-Diethyl-m-aminophenol sulfate is the sulfate salt of N,N-diethyl-m-aminophenol, regulated under EU Regulation 1223/2009 Annex II entry 1223, the same restriction code as the parent compound. The sulfate salt is used primarily to improve aqueous solubility and stability in hair dye formulations. The restriction under entry 1223 limits its use in cosmetic hair dye products to specific concentrations and application types. Like other aromatic amine hair dye intermediates, it can cause allergic contact dermatitis in sensitized individuals. The diethylamino substitution reduces some of the acute toxicity concerns relative to primary and secondary amine analogs, but the sensitization potential remains a significant consideration for both professional formulators and consumers.
