PEG-12 Glyceryl Dimyristate
What is PEG-12 Glyceryl Dimyristate?
PEG-12 Glyceryl Dimyristate is a synthetic compound formed by ethoxylating glyceryl dimyristate, a diester of glycerol and myristic acid—a medium-chain saturated fatty acid sourced from plant oils like coconut or palm kernel. The 'PEG-12' indicates attachment of a 12-unit polyethylene glycol chain, enhancing water solubility. Primarily used in skincare as a skin conditioning agent, emulsifier, and surfactant, it works by lowering interfacial tension between oil and water phases, promoting stable formulations in creams, lotions, and cleansers. Its lipophilic fatty portions deposit on skin to form a protective layer, aiding hydration retention and improving spreadability, while the hydrophilic PEG chain ensures compatibility in aqueous systems without pore-clogging effects.
