Description
Trilinolein (CAS 537-40-6, EC 208-666-6), also known as Glycerol Trilinolate and Trilinoleoylglycerol, is a triglyceride composed of three linoleic acid (C18:2, cis-9,12) chains esterified to a glycerol backbone. It carries no assigned E-code and is classified within the Oils, Fats and Waxes category.
In food and nutrition formulations, trilinolein serves as a lipid carrier and emulsification agent, enabling uniform dispersion of fat-soluble actives within oil-in-water systems. In personal care applications, it functions as a skin-conditioning humectant, integrating into lipid barrier structures to reduce transepidermal water loss. Pharmaceutical formulators use it as a solvent carrier for lipophilic drug compounds in soft-gel and emulsion delivery systems.
Trilinolein is supplied as a liquid and is subject to REACH registration requirements for European commerce. Procurement teams should confirm supplier documentation against relevant food-grade or pharmaceutical-grade standards where applicable. HS code 1302190200 applies for import and customs classification purposes.
