What is GLYCERYL STEARATE used for?

Glyceryl stearate provides multiple benefits for the skin and hair. This is why it is used in thousands of cosmetic, skin care, and hair care products such as skin cleansers, foundations, eyeliners, and shampoos.

  • Skin care: It is a humectant that draws water to the top most layer of the skin and binds it there to provide intense hydration. It also acts as a thickener to maintain the texture and spreadability of the products
  • Hair care: It is used to bring luster and shine to the shafts by bringing back the lost water content. This ingredient also has foaming properties that make it a great choice for products such as shampoos
  • Cosmetic products: It acts as a surfactant. It is a good preservative that keeps cosmetic products from going bad by increasing their shelf life. Cosmetics with Glyceryl stearate do not dry easily and provide hydration to the skin

Origin

Glyceryl stearate is simply the reaction of stearic acid and glycerin. Stearic acid is a fatty acid that is derived from vegetable or animal fats and oils such as coconut and palm. This ingredient is reacted with glycerin and the resultant is further reacted with sodium hydroxide or potassium. This produces a waxy solid substance known as Glyceryl stearate.
