Polyglyceryl-2 Dipolyhydroxystearate
What is Polyglyceryl-2 Dipolyhydroxystearate?
Polyglyceryl-2 Dipolyhydroxystearate is a non-ionic emulsifier formed by esterifying polyglycerol-2, derived from polymerized vegetable glycerin, with polyhydroxystearic acid from hydrogenated castor oil. It falls under polyglyceryl ester surfactants widely used in skincare and makeup products, especially water-in-oil emulsions like creams and balms. By reducing surface tension at the oil-water interface, it promotes stable blending of immiscible phases, preventing separation and ensuring consistent texture. Its lipophilic nature allows it to form a breathable film on skin, aiding in moisture retention and enhancing product spreadability. This multifunctional ingredient supports formulation integrity while delivering a soft, non-greasy finish in anhydrous or high-oil content items.
