About
4-Ethoxybenzene-1,3-diammonium dichloride is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
4-Ethoxybenzene-1,3-diammonium dichloride is a substituted phenylenediamine salt used as a primary intermediate in oxidative hair dyeing. The ethoxy group modifies the dyeing properties while the ammonium salt form improves water solubility. GHS hazard statements (H315 skin irritation, H319 eye irritation, H335 respiratory irritation) indicate it requires careful handling during formulation. Like other aromatic diamines used in hair dyes, it can cause sensitization in predisposed individuals.
