  • Applications

    Sodium Myristoyl Isethionate (CAS 37747-10-7) is a mild anionic surfactant used as a primary cleansing agent in personal care products such as facial cleansers, shampoos, and body washes; it also appears in household cleaners as a gentle foaming surfactant and emulsifier, and is used in industrial formulations as an oil-in-water emulsifier and emulsion stabilizer; in coatings, inks, and plastics processing it serves as a wetting and dispersing agent to improve substrate wetting and formulation stability.
