Used as an emollient in cosmetics and personal care products, ethyl stearate helps soften and smooth the skin. It is commonly found in lotions, creams, and makeup due to its ability to improve texture and spreadability. It also acts as a lubricant in topical formulations, enhancing the feel during application. In industrial applications, it serves as a plasticizer and solvent in coatings and inks. Additionally, it is used in fragrances as a fixative to help stabilize and prolong scent.
