Emulsifier and surfactant

Overview

An ester of glycerin and stearic acid, used as an emulsifier, emollient, and thickening agent in cosmetic formulations.
Emulsifiers/Surfactants In skincare, Glyceryl Stearate functions as an emollient and occlusive, creating a protective barrier that significantly reduces transepidermal water loss, thereby deeply hydrating and softening the skin. It also acts as a crucial emulsifier, blending oil and water phases to stabilize formulations, improve product texture, and enhance spreadability for a smooth application.
