  • Applications

    Phenethyl cinnamate (CAS 103-53-7) is used primarily as an odorant and fixative in perfumery, helping to extend fragrance longevity in perfumes, cosmetic products, and scented coatings. It functions as a fragrance ingredient in cosmetics and personal care formulations, contributing a floral note and enhancing fragrance stability. It is also employed as an intermediate in the synthesis of related fragrance materials and aroma esters. In industrial product formulation, it may be included in coatings, inks, and cleaning products to impart a pleasant aroma. Its use is typically subject to local regulations and formulation-specific limits.
