Dimethyldioctadecylammonium chloride, or distearyl dimethyl ammonium chloride, is a quaternary ammonium salt consisting of a nitrogen atom substituted with two methyl groups and two octadecyl groups. The long-chain hydrocarbon groups combined with the ionic nature of the amine group enables it to act as a surfactant or a detergent.

In household products, it may be found as an ingredient in fabric softeners, cosmetics, and hair conditioners in which it is added primarily for its antistatic effects.[1] It is also used in organic synthesis as a phase transfer catalyst to increase reaction rates in a two-phase organic-water system.

Dimethyldioctadecylammonim Chloride is also listed as: Distearyldimonium Chloride, Dimethyldistearylammonium Chloride, DDAC.[2]
