  • Applications

    Hydroxypropyl bisstearyldimonium chloride (CAS 118516-74-8) is a cationic surfactant commonly used as a conditioning agent in cosmetics and personal care, providing slip, detangling, and a soft feel in hair care formulations. It is also employed in textile and fabric care products as a fabric softener and antistatic additive, improving hand feel and reducing static buildup. In industrial manufacturing, it can function as a surfactant and processing aid in polymer and coating formulations, aiding dispersion, wetting, and leveling. It is sometimes used in cleaners and household products to enhance emulsification and soil-release properties. Additionally, in coatings and inks it may serve as a surfactant to improve wetting and film formation, and as a conditioning additive in adhesives or bond finishes where a soft touch is desired. Formulation use should comply with local regulations and limits.
