Hydroxyethyl Oleyl Dimonium Chloride

What is Hydroxyethyl Oleyl Dimonium Chloride?

Hydroxyethyl Oleyl Dimonium Chloride is a quaternary ammonium salt, featuring a positively charged nitrogen atom linked to hydroxyethyl and oleyl (unsaturated C18) alkyl chains, with chloride as the counterion. Derived from oleic acid sources, it belongs to the dialkyldimonium chloride family of cationic surfactants. Primarily used in rinse-off hair care formulations like conditioners and detanglers, it functions by adsorbing onto the negatively charged hair surface due to electrostatic attraction. This deposition forms a lubricious film that minimizes inter-fiber friction, neutralizes static buildup from shampooing, and imparts a silky texture, aiding in comb-through and styling without residue in typical low concentrations.
