Glyceryl Stearate SE
What is Glyceryl Stearate SE?
Glyceryl Stearate SE is a mono- and diglyceride ester formed by combining glycerol with stearic acid, a saturated fatty acid typically sourced from vegetable oils like palm or soy. This self-emulsifying variant contains potassium stearate, enabling it to function without co-emulsifiers. Primarily used in oil-in-water emulsions, it appears in moisturizers, lotions, foundations, and cleansers within the cosmetic industry. It operates by lowering surface tension at the oil-water boundary, forming a stable interfacial film that prevents phase separation and delivers uniform texture. Its waxy nature also enhances spreadability and provides a protective barrier, supporting the even application of active ingredients while contributing to the product's emollient feel.
