About this ingredient

Laureth-4 is a nonionic surfactant and emulsifier derived from lauryl alcohol ethoxylate, commonly used in cosmetic formulations to solubilize oils, improve product texture, and enhance ingredient stability. It functions as a gentle cleansing agent and helps create stable emulsions in creams, lotions, and cleansers while providing mild conditioning properties to the skin.
