  • Applications

    Santalyl phenylacetate (CAS 1323-75-7) is primarily used as a fragrance ingredient in perfumery and cosmetics, providing a sandalwood-like note and, in some formulations, acting as a fixative to help extend aroma. It can also be employed in household products such as air fresheners and surface cleaners to impart a sandalwood scent, and in coatings, paints and inks where fragrance release or enhancement is desired. The compound may be considered for use in polymer and plastic formulations to contribute scent or scent-release characteristics, and its use is typically governed by local regulations and formulation limits.
