  • Applications

    Azeloyl diethyl salicylate (CAS 207972-39-2) is primarily used in fragrance and cosmetic applications where it functions as a long-lasting fixative and fragrance component, and as a solubilizer or carrier for fragrance oil in perfumes, lotions, and other personal care products. It may also serve as an emollient-like processing aid in cosmetics and as a plasticizer or processing additive in select polymer, coating, or adhesive formulations. In household products and air fresheners, it contributes fragrance notes and helps stabilize blends. In industrial manufacturing it is sometimes evaluated or used as an intermediate or specialty additive in fragrance chemistry and related formulations. It is subject to local regulations and formulation limits.
