Clinical Summary
Oleth-20 is a polyethylene glycol ether of oleyl alcohol used as an emulsifying agent in cosmetics. It may cause skin irritation in some individuals, and there is a potential risk of contamination with ethylene oxide and 1,4-dioxane, which are considered carcinogens. However, these impurities are typically present at very low levels and are regulated in cosmetic formulations.
