  • Applications

    Dodecyltrimethylammonium bromide (CAS 1119-94-4) is a cationic surfactant with a C12 alkyl chain. In practical applications, it is used as a surfactant, emulsifier, and wetting agent in cleaning formulations and industrial processing; as a dispersant and emulsifier in coatings and inks; as a phase-transfer catalyst and surfactant in emulsion polymerization and polymer manufacture; and as a fabric conditioning agent in textiles and a conditioning ingredient in cosmetics/personal care.
