About this ingredient

Oleth-20 is a polyethylene glycol (PEG) ether of oleyl alcohol, functioning as a non-ionic surfactant and emulsifier in cosmetic formulations. It helps stabilize oil-water mixtures, improves product texture, and enhances the penetration of other ingredients into the skin. It is commonly used in creams, lotions, and cleansing products for its mild cleansing and conditioning properties.
