  • Applications

    Potassium Lauroyl Glutamate is the potassium salt of glutamic acid bearing a lauroyl (C12) tail, typically used as a mild surfactant and emulsifier. In practice it is employed in cosmetics and personal care as a gentle cleansing/foaming agent and conditioning component for shampoos, face cleansers, and body washes; it is also used in baby and sensitive-skin formulations for its mildness. It is applied in household and industrial cleaners as a mild surfactant for detergents and surface cleaners. It may act as an emulsifier or stabilizer in polymer formulations, coatings, and inks, and can act as a pharmaceutical excipient or formulation aid in topical products, subject to local regulations.
