  • Applications

    Ammonium Lauryl Sulfate, CAS 2235-54-3, is widely used as an anionic surfactant and foaming agent in commercial formulations, with key applications in cosmetics and personal care (shampoos, cleansers, body washes), household cleaning products (dish and surface cleaners), industrial cleaners and degreasers, and in coatings, inks, and adhesives where it acts as a wetting and emulsifying surfactant; it may also serve as an emulsifier or stabilizer in polymer processing or latex formulations.
