  • Applications

    Linoleamidopropyl ethyldimonium ethosulfate (CAS 99542-23-1) is a cationic surfactant derived from linoleic acid that is typically used as a conditioning and surface-active ingredient in cosmetic and personal-care formulations (such as shampoos, conditioners, and body washes) to improve detangling, softness, and feel. It also serves as a surfactant and emulsifier in household cleaners and detergents, helping wetting, dispersion, and stable mixtures. In industrial manufacturing, it can function as an emulsifier, surfactant, and compatibility additive in polymer, plastics, and coating systems to improve wetting, dispersion of fillers, and formulation stability. It may also be used in coatings and ink formulations as a wetting and leveling agent, and in textile finishing as a softening/conditioning additive. Use is subject to local regulations and formulation limits.
