Polyglyceryl-2 Distearate

What is Polyglyceryl-2 Distearate?

Polyglyceryl-2 Distearate is a diester formed by reacting polyglycerol-2—a short-chain polymer from vegetable-derived glycerol—with stearic acid, a saturated fatty acid from plant or animal fats. Classified among non-ionic polyglyceryl esters, it serves as a versatile cosmetic ingredient in emulsion-based products like moisturizers, sunscreens, and mild cleansers. Its primary function involves reducing interfacial tension between immiscible oil and water phases, forming a protective film that maintains emulsion stability and prevents phase separation. As a surfactant, it also enables light foaming and aids in dispersing ingredients evenly, contributing to products with creamy consistency and improved spreadability without compromising mildness.
