  • Applications

    Ethyl nonadecanoate (CAS 18281-04-4) is the ethyl ester of nonadecanoic acid and is used as a fragrance ingredient and fixative in perfumery; it acts as an emollient and carrier oil in cosmetics and personal care; it serves as a plasticizer and processing aid for polymers and plastics; it can be used as a solvent and softening agent for coatings and inks; it can function as a lubricant in industrial manufacturing; and it may serve as an intermediate in chemical synthesis, with use governed by local regulations and formulation limits.
