  • Applications

    Benzyl lactate (CAS 2051-96-9) is used as a fragrance ingredient and fixative in perfumery, providing a mild, sweet aroma and helping slow evaporation in formulations. In cosmetics and personal care, it functions as an emollient and solvent for fragrance oils and other actives. It also serves as a solvent or processing aid in coatings, inks, and household cleaners, enabling formulation of fragrance-containing products. In polymer and plastics formulations, it may act as a plasticizer or processing aid to improve flexibility and processing characteristics. It is sometimes used as a fragrance solvent in consumer products such as air fresheners, and can serve as an intermediate or carrier in various formulation matrices. Subject to local regulations and formulation limits.
