  • Applications

    N-Dodecyl-N,N-Dimethyl-3-Ammonio-1-Propanesulfonate (CAS 14933-08-5) is a zwitterionic surfactant commonly used as a mild surface-active agent in personal care formulations (shampoos, cleansers, and body washes), delivering effective cleansing with a soft skin feel; it serves as a surfactant and emulsifier in household and industrial cleaning products to improve wetting, detergency, and emulsification; it functions as a stabilizer/co-surfactant in polymer and latex emulsions, coatings, and inks to enhance rheology, dispersion, and film formation; it can act as a dispersant for pigments in formulated products and as a processing aid in textile and coating applications, offering compatibility with other surfactants and polymers while maintaining mildness.
