PEG-20 Glyceryl Isostearate
PEG-20 Glyceryl Isostearate is a PEG-modified glyceryl ester of isostearic acid, chemically described as poly(oxy-1,2-ethanediyl), α,α′,α″-1,2,3-propanetriyltris-ω-hydroxy-, isooctadecanoate with an average of 20 moles of ethylene oxide. It is classified as a surfactant/cleansing agent under CosIng. It is commonly found in cleansing balms, cleansing oils, and cleansing gels, often functioning as an emulsifier to help oil-based formulas rinse off with water.
As a surfactant and emulsifier, PEG-20 Glyceryl Isostearate helps solubilize and remove makeup, sebum, and impurities from the skin. Its ethoxylated structure allows oil-based cleansing products to emulsify upon contact with water, facilitating rinsing.
As a PEG-derived ingredient, individuals with sensitivity to ethoxylated compounds should exercise caution. No additional specific cautions are noted in the source.
