Olealkonium Chloride
What is Olealkonium Chloride?
Olealkonium chloride is a synthetic quaternary ammonium salt featuring a long-chain oleyl alkyl group (unsaturated C18 hydrocarbon), dimethyl ammonium, benzyl substituent, and chloride counterion. This cationic surfactant is commonly incorporated into rinse-off hair care formulations like conditioners, detanglers, and leave-in styling products. It functions through electrostatic attraction to the negatively charged hair keratin surface, depositing a substantive conditioning film. This layer minimizes inter-fiber friction, neutralizes static buildup by enhancing conductivity, promotes slip for easier combing, and boosts overall hair luster and suppleness. Its biocidal action disrupts microbial cell membranes, safeguarding product integrity against contamination during use.
