What is Glyceryl Linolenate?

Glyceryl Linolenate is the glycerol ester of linolenic acid, a polyunsaturated omega-3 fatty acid primarily sourced from plant oils such as flaxseed or chia seed oil. This lipid compound belongs to the class of monoacylglycerols, naturally occurring in vegetable fats. In cosmetics, it functions mainly in leave-on and rinse-off products like creams, lotions, shampoos, and conditioners. As an emollient, it lubricates the skin's surface, reducing dryness by mimicking the skin's natural oils and enhancing product spreadability. Its emulsifying properties help stabilize oil-in-water formulations, preventing separation for smoother textures. The surfactant action aids in gentle cleansing by lowering surface tension without harshness. Derived through esterification, it provides a lightweight, non-greasy feel while supporting skin barrier integrity through fatty acid delivery.
