  • Applications

    Triethanolamine Lauryl Sulfate (CAS 139-96-8) is an anionic surfactant used as a foaming agent, emulsifier and cleanser in a broad range of formulations. In real-world use it supports personal care products such as shampoos, body washes and facial cleansers to enhance foam and cleaning performance; household cleaners including dishwashing liquids and multi-surface cleaners; cosmetic cleansers and emulsions; industrial cleaning formulations for institutional or facility cleaning; and coatings, inks and polymer systems where it acts as a dispersant or emulsifier to improve pigment stabilization and formulation stability.
