  • Applications

    Decyl dimethyl octyl ammonium chloride (CAS 32426-11-2) is a quaternary ammonium salt that functions primarily as a cationic surfactant with antimicrobial properties. It is commonly used in cleaning and disinfection formulations for hard surfaces (household and industrial) and serves as a conditioning and anti-static agent in textiles and personal care products. It acts as a surfactant, wetting agent, and anti-static/conditioning additive in coatings, inks, and adhesives. In broader industrial manufacturing, it is employed as an emulsifier/surfactant in polymer processing and in specialty cleaning formulations for metalworking fluids or manufacturing aids.
