  • Applications

    Butyloctyl Benzoate (CAS 188038-97-3) is commonly used as an emollient and solvent in cosmetics and personal care formulations, improving skin feel and helping dissolve fragrance and active ingredients. In perfumery, it acts as a fragrance solvent and carrier for aroma compounds. It is also used as a plasticizer and solvent in coatings and inks, and as a processing aid in industrial polymer formulations. In household products, it serves as a conditioning emollient and solvent base to improve texture and formulation stability.
