Used as an emulsifier and surfactant in cosmetic and pharmaceutical formulations. Helps stabilize oil-in-water emulsions by reducing surface tension between ingredients. Commonly found in skin care products like creams and lotions, where it improves texture and enhances the spreadability. Also aids in the uniform dispersion of active ingredients. Its oleic acid content provides mild conditioning properties, making it suitable for products designed for dry or sensitive skin. Often combined with other emulsifiers to optimize emulsion stability and performance.
