  • Applications

    Potassium Myristoyl Glutamate (CAS 72716-26-8) is a mild anionic surfactant derived from glutamic acid and a C14 fatty acyl chain. In cosmetics and personal care, it is used as a gentle cleansing surfactant in shampoos, facial cleansers, and body washes, offering adequate foam with a low irritation potential and good skin compatibility. In household and industrial cleaners, it serves as a mild surfactant and emulsifier to improve soil dispersion, wetting, and rinse performance. In coatings and inks, it functions as a surfactant to improve pigment dispersion, surface wetting, and formulation stability. In polymers and plastics processing, it may act as a processing aid or emulsifier in latex and dispersion systems, aiding particle stability and compatibility with other formulation components. Subject to local regulations and formulation limits.
