  • Applications

    Hexyl 2-hexenoate, (2E)- is primarily used as a fragrance ingredient and odorant in perfumery, contributing fruity and green notes to aroma blends. It is commonly evaluated for cosmetic and personal care applications as a fragrance component. In household products and cleaners it can provide a pleasant scent as an odorant additive. In industrial manufacturing it may serve as an intermediate in the synthesis of other aroma compounds or related esters. It is also employed in coatings and inks where a fragrance contribution is desired, subject to formulation limits and local regulations.
