  • Applications

    Decyl isooctanoate (CAS 84878-25-1) is used in cosmetics and personal care as an emollient and solvent, delivering a smooth feel on the skin and helping dissolve and blend other ingredients. It also commonly serves as a fragrance carrier or solvent in perfumery, supporting formulation of scented products with favorable volatility and compatibility. In coatings, inks, and adhesives, it can function as a processing solvent or plasticizer, aiding film formation and flexibility. It may also be considered an intermediate or solvent in industrial manufacturing and formulation development, where it helps dissolve oils and resins. In household and cleaning products, it can act as a solvent or carrier for actives and fragrances, contributing to ease of use and formulation stability.
