  • Applications

    Na4P4O12 (Sodium tetraphosphate, CAS 14986-84-6) is used as a chelating agent and water-softening additive in household and industrial cleaning products to reduce water hardness and stabilize formulations; it serves as a buffering/pH-stabilizing component in processing aids; it may function as a corrosion inhibitor or anti-scaling additive in water treatment and metalworking fluids; it acts as an intermediate in the synthesis of phosphate-containing compounds; it is used as a dispersant/stabilizer in coatings and inks; and it may be evaluated as a precursor for polymer and plastics processing.
