  • Applications

    Magnesium laureth-3 sulfate (CAS 101621-38-9) is an anionic surfactant commonly used as a cleansing agent, emulsifier and foaming aid in cosmetics and personal-care products, including shampoos, body washes and facial cleansers. It also functions as a surfactant and wetting agent in household and industrial detergents and cleaners, such as dishwashing liquids and all-purpose cleaners. Additionally, it acts as a dispersing and emulsifying aid in coatings and inks, and as an emulsifier in polymer and latex formulations. Its use is subject to formulation requirements and local regulations.
