  • Applications

    Ethyl oleate (9-Octadecenoic acid, ethyl ester; CAS 6114-18-7) is a non-volatile, lipophilic solvent and carrier widely used in cosmetics and personal care as an emollient and solvent for fragrances and lipophilic actives; it is also employed as a solvent and carrier in pharmaceutical lipophilic formulations and in fragrance applications. It is used as a plasticizer and processing aid in coatings, inks, and adhesives to modify film properties and adhesion. It also serves as a base oil and lubricant in industrial lubricants and maintenance products, providing long-lasting lubrication and compatibility with other formulation components. Additionally, it participates in polymer processing and is used as a lipid-based delivery system component in lipid-based formulations and emulsions for pharmaceutical and fragrance applications.
