Used as a surfactant and emulsifying agent in cosmetic and personal care formulations. It helps stabilize mixtures of oil and water, making it useful in creams, lotions, and cleansers. Also functions as a detergent and foam booster in mild cleansing products. Its sulfate-based structure provides good water solubility and surface activity, enhancing the spreadability and performance of topical formulations. Commonly found in shampoos and body washes for its ability to lift dirt and oil from skin and hair.
