PEG-23 Glyceryl Distearate
What is PEG-23 Glyceryl Distearate?
PEG-23 Glyceryl Distearate is a synthetic polyethylene glycol ether of glyceryl distearate, formed by reacting glycerol distearate—a diester of glycerin and stearic acid—with approximately 23 moles of ethylene oxide. This process creates a water-soluble, mildly hydrophilic ingredient widely employed in skincare as an emollient and emulsifying agent. In cosmetic products like moisturizers, lotions, and creams, it functions by depositing a thin lubricating film on the skin, reducing friction for easier application and a smoother feel. It also stabilizes oil-in-water emulsions by lowering interfacial tension between phases, preventing separation. The ethoxylation degree provides balanced solubility, making it suitable for both rinse-off cleansers and leave-on treatments, contributing to lightweight, non-sticky consistencies without heavy occlusion.
