  • Applications

    Amyl oleate (CAS 142-57-4) is used primarily in fragrance applications as an odorant and fixative component in perfumery, contributing fruity-oleaginous notes and helping stabilize aroma blends. In cosmetics and personal care, it often serves as a solvent and carrier oil, aiding fragrance delivery and functioning as an emollient in lotions, creams, and other scented formulations. It may also be employed as a processing aid or plasticizer in certain polymer and coating systems, imparting flexibility and influencing texture. In household products and cleaning formulations, it can act as a solvent or fragrance carrier to assist formulation performance. In industrial manufacturing, amyl oleate is used as a non-volatile solvent or diluent for active ingredients and as a medium for fragrance loading; it may also appear as an intermediate in fragrance compound synthesis. Subject to local regulations and formulation limits.
