  • Applications

    Sodium Methyl Palmitoyl Taurate (CAS number: 3737-55-1) is used as a mild surfactant across cosmetics, household and industrial cleaners, and related formulations. In cosmetics and personal care, it functions as a cleansing, foaming, emulsifying, and wetting agent in products such as shampoos, facial cleansers, and body washes. In household and industrial cleaners, it acts as a surfactant that improves dirt removal and formulation stability. In coatings, inks, and polymer systems, it serves as an emulsifier and wetting agent to aid dispersion and film formation. It may also be used as a surfactant excipient in topical pharmaceutical formulations, subject to regulatory requirements.
