  • Applications

    Decyl isononanoate (CAS 84878-31-9) is primarily used as an emollient in cosmetics and personal care, delivering a light, non-greasy skin feel in lotions, creams and body oils. It also serves as a solvent and carrier for fragrance ingredients in perfumery, helping to solubilize actives and stabilize fragrance blends. In hair care, it functions as a conditioning agent and slip enhancer in conditioners and styling products. In household products, it acts as an emollient and fragrance vehicle in surface cleaners and bath products. In some industrial formulations it can be used as a processing aid or solvent component, subject to formulation requirements and regulatory limits.
