  • Applications

    Sodium Xylenesulfonate (CAS 1300-72-7) is a water-soluble anionic surfactant commonly used in household and industrial cleaners to provide wetting, detergency and emulsification. It also serves as a dispersant and leveling agent in coatings and inks, improving pigment dispersion and flow. In polymer and plastics processing, it acts as an emulsifier and stabilizer in latexes and blends. In textiles and dyeing, it serves as a surfactant to improve wetting and dye uptake. In agriculture, it is used as a spray adjuvant to improve deposition on leaves. In cosmetics and personal care, it functions as a cleansing surfactant and formulation stabilizer.
