  • Applications

    3-Phenylpropyl isovalerate (CAS 5452-07-3) is primarily used as a fragrance ingredient and odorant in perfumery, where it contributes floral-woody notes and can act as a mild fixative to help stabilize complex scent profiles. It is commonly incorporated into cosmetics and personal care formulations such as creams, lotions, and bath products to impart a pleasant aroma. In household products, it serves as a fragrance component for air fresheners, cleaners, and detergents. It may also be evaluated as a flavor/fragrance ingredient in limited, regulated food or beverage applications where permitted. Additionally, this ester can be employed in coatings and inks to impart scent, and may be used as an intermediate in fragrance synthesis within industrial manufacturing. All uses are subject to local regulations and formulation limits.
