It is also used as cleansing agent in shampoo, shower gel, face wash; as an emulsifying agent to promotes the formation of intimate mixtures between immiscible liquids by modifying the interfacial tension (water and oil) in creams, lotions; and as a surfactant to reduce the surface tension of cosmetics and contributes to the even distribution of the product during use.
