Glyceryl Stearate

Glyceryl stearate is a mixture of portions of glycerin and stearic acid. Although it occurs naturally in the human body and can be derived from animals, most glyceryl stearate used in cosmetics is plant-derived (such as from olive or coconut oil) or synthetically produced. In its raw form, it is a white or cream-colored wax-like solid.
Glyceryl stearate acts as an emollient, surfactant and emulsifier in skin care products. Its emulsifying properties are very versatile, making it a valuable and gentle addition to several types of emulsions, such as oil-in-water or water-in-oil, where it helps support the benefits of skin-regenerating ingredients such as ceramides and lipids. acids. Its moisturizing properties help skin look and feel softer and smoother. It also forms a barrier on the skin that helps prevent water loss. In addition, glyceryl stearate is used as a food additive.
The Cosmetics Ingredient Review Panel has found glyceryl stearate to be safe within its typical use levels of 1-10%. Studies have also shown that it is not sensitizing, and plant-derived glyceryl stearate is permitted for use in cosmetics and personal care products marketed in Europe.
