What Glycol Stearate does

Gives creams and shampoos a soft, pearly look
Adds light body and a fuller texture
Helps thicken and steady creamy formulas

Glycol Stearate is made by reacting ethylene glycol, a simple building block used in many esters, with stearic acid. Stearic acid is a common fatty acid found in plant and animal fats. The result is a waxy solid, usually a blend of mono- and di-esters.

Formulators use it mainly as a pearlizer. Its tiny crystals scatter light, so lotions and shampoos look soft and pearly instead of flat or clear. It also adds body, so creams feel fuller, and it leaves a smooth, silky feel that does not read as oily in typical amounts.

Good for

Suits body lotions and shampoos that aim for a soft, pearly look and a smooth, light feel.
