Glyceryl Stearate is an emollient, emulsifier, emulsion stabilizer, viscosity builder and moisturizer and can be found in lotions, cleansers, creams, sunscreen and suntanning products, and hair conditioners and hair rinses.
Glyceryl Stearate helps to form an emulsion by creating a reduction in the surface tension of the substances that are to be emulsified. In cosmetics it is employed as a pearlizing and opacifying agent in makeup bases and foundations, eyeliner, mascara, eyeshadow and powders. It is also used in the treatment of eczema, as a humectant, as a solvent and in drug delivery.
Due to Glyceryl Stearates emollient and humectant properties, it is lubricating on the skin and gives skin a smooth and soft appearance. It is also able to create a barrier on the surface of the skin, slowing down any water loss.

It is categorized as an anionic modified emulsifier and is recommended to be used in water or oil emulsions that are between the pH range of 5-9. It is used in cosmetics and creams at the amounts of .5-2% w/w. It is typically used with other emulsifiers such as ceteareth 20 or polysorbate 20.
