  • Applications

    Tricaprin, a tri-caprylate glyceride (CAS 621-71-6), is a medium-chain triglyceride commonly used as an emollient and oil carrier in cosmetics and personal care products, providing softening feel and good spreadability in creams, lotions, and lip products. It also serves as a solvent and carrier for fragrances and other lipophilic ingredients in perfumery and flavor applications. In pharmaceutical formulations, it functions as a lipid-based excipient and solvent for lipophilic actives, aiding solubility and controlled release in certain dosage forms. In industrial and polymer-related contexts, tricaprin can act as a processing oil or plasticizer in select polymer/coatings formulations, helping to improve processability and flexibility. It may also be used as a neutral oil base in household cleaning products and other formulation matrices, contributing to solvency and texture. Subject to local regulations and formulation limits.
