Glyceryl Stearate, sometimes also referred to as monostearate, is a natural vegetable-derived ester that usually comes in the form of grainy white flakes. It is a non-ionic ingredient known to provide skin with incredible hydration. When used in soaps, lotions or creams, glycerin acts as a protective layer over skin to retain moisture. It can also enhance the texture of many formulas by increasing its silky feel.
