Used as a mild anionic surfactant and emulsifier in cosmetic and personal care formulations. It helps stabilize emulsions and improves texture in creams and lotions. Due to its amino acid-based structure, it is biodegradable and skin-compatible, making it suitable for sensitive skin products. Commonly found in facial cleansers, baby care items, and moisturizers where gentle cleansing and low irritation are important. Also functions as a foam booster and viscosity modifier in liquid soaps and shampoos.
