  • Applications

    Potassium Undecylenoyl Glutamate (CAS 280576-95-6) is a mild surfactant and emulsifier used in cosmetics and personal care as a gentle cleanser, conditioning aid, and texture-enhancing ingredient, notably in shampoos, facial cleansers, and body washes. It is also evaluated as a milder surfactant alternative in household and industrial cleaners, helping to provide foaming and cleaning efficiency with lower irritation. In coatings and inks, it can function as a wetting agent and dispersant to improve substrate interaction. In polymer formulations and emulsions, it may serve as an emulsifier or processing aid; it may be used as an additive in pharmaceutical topical products, subject to local regulations and formulation limits.
