Distearyl dimethyl ammonium chloride is an organic compound classified as quaternary ammonium salt. The nitrogen center substituted with two methyl groups and two stearyl groups. The combination of long-chain hydrocarbon groups and the cationic ammonium confers surfactant- or a detergent-like properties. It was once a major component of fabric softeners, but has been largely phased out because of its low biodegradability.[1] In household products, it may also be found as an ingredient in cosmetics and hair conditioners in which it is added primarily for its antistatic effects.[2] It is also used in organic synthesis as a phase transfer catalyst to increase reaction rates in a two-phase organic-water system.
