  • Applications

    Oleyl stearate is the ester of oleyl alcohol and stearic acid used primarily as an emollient in cosmetics and personal care, providing slip and a smooth skin feel. In perfumery/fragrance applications it often serves as a solvent or carrier for fragrances and helps stabilize product texture. In coatings and plastics it is employed as a lubricating agent and plasticizer or as a softening additive in polymer and paint systems. In industrial manufacturing it can act as an intermediate solvent or a carrier oil in cleaning formulations and process aids. Overall, common use areas include cosmetics/personal care, perfumery/fragrance, polymers/plastics, coatings/inks, and cleaning formulations, with roles as emollient, fragrance solvent carrier, lubricant or plasticizer depending on formulation and local regulations.
