Formula IngredientEmollient, EmulsifierGlyceryl Stearate
INCI: Glyceryl Stearate
Glyceryl stearate is the monoester of glycerin and stearic acid — essentially one glycerin molecule bonded to a stearic acid fatty acid chain. It occurs naturally in the body and is also derived from vegetable oils via a green, soap-like manufacturing process. In formulations it functions as both an emulsifier (helping oil and water phases blend stably) and a skin-conditioning emollient that leaves skin feeling soft and smooth.
