  • Applications

    3-Octyl acetate (CAS 4864-61-3) is an ester with a fruity note, widely used as a fragrance ingredient and solvent in perfumery, cosmetics, and personal care products. It also serves as a solvent for resins, coatings, inks, and adhesives in industrial settings, and can function as a fragrance component in household products and cleaners. In food processing, 3-Octyl acetate may be used as a flavor or aroma ingredient, subject to local regulations and formulation limits. Additional potential uses include applications in polymer and coating formulations where it acts as a solvent or aroma carrier, under regulatory constraints.
