Used as an emollient in cosmetics and personal care products, ethyl stearate helps improve texture and spreadability in lotions, creams, and makeup. It provides a smooth, non-greasy feel on the skin by forming a protective barrier that locks in moisture. Commonly found in hair conditioners and styling products, it reduces frizz and enhances shine. In industrial applications, it serves as a lubricant or plasticizer in formulations requiring low volatility and good stability. It is also used as a solvent or carrier in fragrances and flavorings due to its mild odor and compatibility with other ingredients.
