Overview
Glyceryl triolein, commonly known as triolein, is a natural triglyceride formed by the complete esterification of glycerol with three molecules of oleic acid. It is a major component of many vegetable oils, including olive, sunflower, and canola oils. Triolein is widely used as an emollient, skin-conditioning agent, and texture enhancer in cosmetic and personal care products. In the food industry, it serves as a natural fat component in cooking oils, margarines, and specialty fat blends. Its excellent biocompatibility, low toxicity, and moisturizing properties make it a valuable ingredient across multiple industries.
