What Is It?

Glyceryl Stearate and Glyceryl Stearate SE are esterification products of glycerin and stearic acid. Glyceryl Stearate is a white or cream-colored wax-like solid.

Glyceryl Stearate SE is a "Self-Emulsifying" form of Glyceryl Stearate that also contains a small amount of sodium and or potassium stearate.

In cosmetics and personal care products, Glyceryl Stearate is widely used and can be found in lotions, creams, powders, skin cleansing products, makeup bases and foundations, mascara, eye shadow, eyeliner, hair conditioners and rinses, and suntan and sunscreen products.

Why is it used in cosmetics and personal care products?

Glyceryl Stearate acts as a lubricant on the skin's surface, which gives the skin a soft and smooth appearance. It also slows the loss of water from the skin by forming a barrier on the skin's surface. Glyceryl Stearate, and Glyceryl Stearate SE help to form emulsions by reducing the surface tension of the substances to be emulsified.

Safety Information: 

The Food and Drug Administration (FDA) includes Glyceryl Stearate (also called glyceryl monostearate) in its list of direct food additives affirmed as Generally Recognized As Safe (GRAS). The safety of Glyceryl Stearate and Glyceryl Stearate SE has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel.

The CIR Expert Panel evaluated the scientific data and concluded that Glyceryl Stearate and Glyceryl Stearate SE were safe for use in cosmetics and personal care products.

More safety Information: 

CIR Safety Review: The CIR Expert Panel reviewed chronic studies of Glyceryl Stearate that showed no adverse effects on reproduction, and no carcinogenic effects.

Human exposure studies of products containing Glyceryl Stearate and Glyceryl Stearate SE, as well as clinical experience have shown these compounds to be nonsensitizing, nonphototoxic and nonphotosensitizing.
