About
A PEG-modified coconut fatty acid amide used as a gentle surfactant and emulsifier. Safe on intact skin; CIR advises against use on broken skin.
PEG-20 Cocamide (CAS 68425-44-5) is a nonionic surfactant made by ethoxylating coconut-derived fatty acid amides with about 20 moles of ethylene oxide. It functions as an emulsifier, foam booster, thickener, and mild cleansing agent. The CIR Expert Panel has reviewed PEG cocamide derivatives and concluded they are safe for cosmetic use on intact skin, with the caveat not to apply on damaged or burned skin due to observed kidney effects of PEGs in burn patients. Purified grades have negligible residual 1,4-dioxane; lower-quality grades warrant more concern.
