  • Applications

    butyl (9Z,12Z,15Z)-9,12,15-octadecatrienoate (CAS 38370-68-2) is primarily used as an emollient and conditioning agent in cosmetics and personal care, and as a solvent and fragrance carrier in perfumery. In coatings and inks, the ester can serve as a plasticizer and processing aid to improve glide and film properties. In plastics and polymer formulations, it is often employed as a plasticizer or additive to enhance flexibility and processability of polymer systems. It also finds use as a solvent and conditioning component in cleaning and household products, aiding dissolution of lipophilic actives. Given its unsaturation and the linolenyl backbone, stabilization considerations and local regulatory constraints may apply.
