What it is
Tribehenin is a saturated triester formed from glycerin and behenic acid (a C22 fatty acid). Its high melting point makes it useful for structuring anhydrous and emulsion systems, raising viscosity and adding a cushiony, non-greasy slip. It is commonly paired with other waxes and oils in sunscreens, foundations, lip products, and balms to improve texture and payoff.
Safety & warnings
Tribehenin is a large, inert fatty triester and is generally well tolerated, with a low expected likelihood of irritation or sensitization. As a heavy, occlusive lipid it may contribute to a richer feel, so individuals prone to congestion may prefer lighter formulas.
Origin & sourcing
Made by esterifying glycerin with behenic acid, which is typically sourced from plant oils such as rapeseed or other vegetable feedstocks, then hydrogenated and purified.
Questions everyone asks
What does tribehenin do in a sunscreen?
It acts as an emollient and thickener, helping structure the base and giving the product a smooth, cushiony feel without a heavy oily finish.
Is tribehenin derived from plants?
It is usually made from behenic acid obtained from vegetable oils such as rapeseed, reacted with glycerin to form the triester.
