Description: Laureth (Lauryl Alcohol Ethoxylate) is a nonionic surfactant derived from the ethoxylation of lauryl alcohol (C12 fatty alcohol). It is available in various ethoxylation degrees, with Laureth-3 (3 EO units) being a low-foaming, oil-soluble emulsifier, and Laureth-23 (23 EO units) being a high HLB, water-soluble emulsifier and solubilizer. These versatile surfactants are widely used in cosmetics, personal care, detergents, industrial cleaning, and various industrial applications as emulsifiers, surfactants, solubilizers, and wetting agents.
