  • Applications

    alpha-Terpinyl acetate, (+)- is primarily used as a fragrance ingredient and fixative in perfumery, contributing floral-citrus notes and providing slower evaporation; it is commonly formulated into cosmetics and personal care products such as creams and lotions to impart scent; in household products like air fresheners and cleaners it serves as a fragrance component to deliver aroma; in coatings, inks, and related polymer systems it can function as a fragrance additive to provide a pleasant odor; and it may be encountered as a constituent of fragrance formulations and intermediates for scent release in various industrial applications, subject to local regulations and formulation limits.
