  • Applications

    Entsufon Sodium (CAS 2917-94-4) is the sodium salt of a sulfonated compound and is used primarily as a surfactant and wetting agent in industrial and household cleaning formulations. It may also function as an emulsifier or dispersant in polymer and plastic processing, helping to stabilize emulsions and improve pigment dispersion. Additionally, it can serve as an additive in coatings and inks to improve wetting and leveling. In cosmetics and personal care, it may act as a cleansing or surfactant component depending on the formulation. It can also find use in adhesives to enhance wetting and adhesion.
