What it is
Glyceryl Behenate is an ester formed from glycerin and behenic acid, a long-chain fatty acid, and behaves as a waxy solid at room temperature. In sunscreens it is used to thicken and stabilize emulsions, control viscosity, and impart a smooth, conditioned feel to the skin. It also helps structure the oil phase and can contribute to a uniform film on application.
Safety & warnings
Glyceryl Behenate is generally well tolerated and has a low irritation and sensitization potential. As a long-chain fatty acid ester it is a heavier, occlusive material, so very acne-prone individuals may prefer to monitor how richer formulas containing it behave on their skin.
Origin & sourcing
Glyceryl Behenate is produced by esterifying glycerin with behenic acid, a long-chain fatty acid commonly sourced from plant oils such as rapeseed or other vegetable sources.
Questions everyone asks
What role does glyceryl behenate play in a formula?
It works as an emollient and emulsion stabilizer, helping thicken the product, control its texture, and give a smooth skin feel.
Is glyceryl behenate plant-derived?
It can be, since the behenic acid used to make it is commonly obtained from vegetable oils such as rapeseed, though it is produced through chemical esterification.
