  • Applications

    Sodium Lauroyl Glutamate (CAS 29923-31-7) is a mild amino-acid–based surfactant commonly used in cosmetics and personal care as a cleansing and emulsifying agent in products such as facial cleansers, shampoos, and body washes; it is also employed in household and industrial cleaners as a gentle surfactant with good foaming and soil-removing properties, and can function as an emulsifier or stabilizer in polymer latexes, paints, and coatings; in pharmaceuticals, it may serve as a surfactant and emulsifier in topical formulations to improve dispersion and stability; overall, it is valued as a biodegradable surfactant suitable for diverse formulated products, subject to local regulations and formulation limits.
