Used as a non-ionic surfactant and emulsifier in cosmetic and pharmaceutical formulations. It helps stabilize oil-in-water emulsions, improving the texture and consistency of creams, lotions, and serums. Its lipophilic nature allows efficient solubilization of oils and active ingredients, enhancing product spreadability and skin penetration. Also employed in drug delivery systems to improve the bioavailability of poorly water-soluble drugs. Commonly found in topical formulations due to its low irritation potential and compatibility with a wide range of ingredients.
