About
Steardimonium Hydroxypropyltrimonium Chloride is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.
Steardimonium Hydroxypropyltrimonium Chloride is a quaternary ammonium salt (quat) used primarily as a hair and skin conditioning agent. It is listed in CosIng with the function of antistatic and conditioning. While generally safe at permitted concentrations, quaternary ammonium compounds can be mild skin and eye irritants and may cause sensitization in susceptible individuals. EU restrictions apply to certain quaternary ammonium compounds; this specific substance is permitted but should be used within established concentration limits.
