Description
Glycerol Tricaprylate (CAS 538-23-8) is a triglyceride ester formed from glycerol and caprylic acid, also known under trade names such as Caprylin, Tricaprylin, and EMALEX OTG. It carries no E-code designation and is distinct from mixed caprylic/capric triglycerides. The molecular formula is C27H50O6.
In pharmaceutical and nutraceutical formulations, it functions as a lipid-based carrier for poorly water-soluble active ingredients, improving oral bioavailability through solubilisation within lipid digestion pathways. In personal care, it acts as an emollient and solvent for oil-soluble actives such as vitamins and UV filters, contributing to skin-feel without occlusive residue.
Glycerol Tricaprylate is available in cosmetic, food-grade, and pharmaceutical grades, with compliance to FCC and Ph.Eur. monographs depending on specification. It falls under REACH registration requirements within the EU. Packaging is typically available in drums and IBCs. HS code: 29159000.
