  • Applications

    Didecyldimethylammonium chloride (CAS 7173-51-5) is widely used as a cationic surfactant and biocidal active ingredient with practical applications across several industries: hard-surface disinfection and sanitation in household, institutional, and industrial cleaning; use as a surfactant and degreasing agent in cleaning formulations; a conditioning/softening surfactant in textile finishing and laundry products; an antimicrobial additive in coatings, paints, and plastic materials; and a sanitation/biofilm-control agent in process water treatment and cooling systems.
