  • Applications

    Trilaurin (CAS 538-24-9) is a triglyceride of lauric acid and serves as a lipid-based ingredient in numerous formulations. In cosmetics and personal care, it is used as an emollient, a slip agent, and a lipid carrier in creams, lotions, and solid bars. In pharmaceutical development, trilaurin can function as a lipid excipient or drug delivery vehicle, aiding solubility and controlled release of lipophilic actives or as a carrier for semi-solid dosage forms. In food processing, as a lauric triglyceride, it may be used as a fat component in specialty fats or formulated ingredients, subject to regulatory approvals. In industrial manufacturing, it can be used as a processing aid or lubricant in processing operations and as a component of lipid-based coatings or ink systems, depending on formulation needs and local regulations.
