Tribehenin is a chemical compound produced synthetically from glycerol and behenic acid in the form of glyceryl tribehenate or glycerol triester. It occurs as a white powder.
What it is used for and where
Food
Utilizzato come emulsionante alimentare.
Cosmetics
Mainly used as a thickening and emulsifying agent in personal care products. Emulsifiers have the property of directly influencing the stability, sensory properties and surface tension of sunscreens by modulating their filmometric performance.
Use: 0.5% to 10% on oil at high temperature and until melting.
Safety
Has been deemed safe for human health by the Cosmetic Ingredient Review Panel (1).
