  • Applications

    Eicosyl butyrate (CAS 41927-66-6) is a long-chain ester used as a fragrance ingredient in perfumery, where it contributes waxy, fruity notes and can act as a fixative to help extend fragrance longevity. In cosmetics and personal care formulations, it is employed as a fragrance component in products such as creams, lotions, and hair-care items. It is also used in household products as a fragrance additive. In coatings and inks, it may function as a plasticizer or processing aid to improve flexibility and film-forming properties. In polymers/plastics, it can serve as a processing aid or plasticizer to modify texture and material properties. It can also be used as an intermediate in industrial fragrance-related manufacturing and synthesis.
