Polyethylene glycol ether of stearyl alcohol (average 21 units -CH2-CH2-O-). The substance promotes the formation of finely distributed mixtures (emulsions) of otherwise immiscible liquids by changing their interfacial tension. It has a purifying effect. As a surfactant it reduces the interfacial tension of cosmetic products and contributes to an even distribution during application.
