Glyceryl monostearate(Cas 31566-31-1) Usage


Glycerin Monostearate (GMS), also known as glyceryl monostearate or E471, is a versatile emulsifier and food additive widely utilized in the food industry. It is formed through the esterification of glycerol, a trihydroxy alcohol, with stearic acid, a fatty acid, resulting in a waxy solid or flakes. GMS serves as a non-ionic surfactant and emulsifier due to its unique molecular structure.

Chemical Properties

Glyceryl monostearate is waxy to the touch and has a slight, mild fatty odor and taste The USP describes glyceryl monostearate as consisting of not less than 90% of monoglycerides, chiefy glyceryl monostearate and glyceryl monopalmitate.


GMS enhances dough stability, texture, and crumb softness in baked goods like bread, cakes, pastries, and cookies.

It is used in chocolates, candies, and confectionery coatings to control viscosity, improve texture, and prevent fat bloom.

GMS serves as an emulsifier and thickening agent in personal care products such as creams, lotions, and cosmetics, imparting a pleasant skin feel.

GMS is generally considered safe for consumption and is widely used in food and cosmetic formulations.
