Octoxynol-20 is a nonionic surfactant formed by the ethoxylation of octylphenol, with an average of 20 moles of ethylene oxide, related to Triton X-100. It is used in cosmetics as an emulsifier and surfactant, though octoxynols are increasingly restricted due to endocrine-disrupting octylphenol degradation products.
