PEG-12 Glyceryl Distearate
What is PEG-12 Glyceryl Distearate?
PEG-12 Glyceryl Distearate is a polyethylene glycol ester formed by reacting glyceryl distearate—a diester of glycerol and stearic acid—with 12 units of ethylene oxide. This ethoxylated compound belongs to the PEG fatty acid ester family, commonly used in skincare formulations like creams, lotions, and conditioners. Chemically, it acts as a surfactant-emulsifying agent and emollient. In products, it functions by reducing surface tension between oil and water phases, enabling stable emulsions that prevent separation. Its emollient properties come from stearate chains that mimic natural skin lipids, providing a smooth, non-greasy feel while aiding in even application. Derived synthetically from plant or petroleum-based fatty acids, it enhances formula spreadability and texture without heavy occlusion.
