  • Applications

    Hexyl oleate (CAS 20290-84-0) is primarily used as an emollient and solvent in cosmetics and personal care, helping soften the skin and dissolve actives and fragrance ingredients. It also serves as a carrier solvent for fragrance oils in perfumery and can act as a plasticizer or processing aid in polymer formulations and coatings to improve flexibility. In cleaning and household formulations, it can function as a low-odor, fatty ester solvent and diluent for formulations. In industrial manufacturing, it may be used as a solvent or processing aid in various chemical syntheses or formulation steps, and as a component in inks and lubricants. It is typically used where a non-polar, lipophilic ester is desired, with use subject to local regulations and formulation limits.
