  • Applications

    Sodium acrylate (CAS 7446-81-3) is primarily used as a monomer and building block for polyacrylate polymers; it serves as a key feedstock for acrylic polymer dispersions and resins used in coatings, inks, and adhesives. It functions as a water-soluble anionic polymer that provides thickening and stabilizing properties in cosmetics, personal care, and household cleaning formulations. It is widely used in water treatment as a scale inhibitor and dispersant for particulates, and as a starting material for superabsorbent polymers employed in hygiene products. It may be incorporated into polymer matrices for plastics, papers, and textiles.
