Description

Hexasodium Tetrahydrogen [[(Phosphonatomethyl)Imino]Bis[Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a high-performance, multi-dentate phosphonate chelating agent and scale inhibitor. This compound is engineered for superior sequestration of di- and trivalent metal ions, particularly calcium, magnesium, and iron, under demanding conditions. It is essential for industrial water treatment, detergent formulations, and processes requiring robust scale and corrosion control. The product is supplied with CAS number 93841-74-8.

Application

• Industrial Water Treatment: Primary application as a highly effective threshold scale inhibitor and dispersant for calcium carbonate, sulfate, and phosphate scales in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a powerful builder and chelant to inactivate water hardness ions, enhancing the cleaning efficiency of laundry detergents, industrial cleaners, and automatic dishwashing products.
• Oilfield & Mining Chemicals: Used in scale squeeze treatments and as a component in drilling fluids to prevent mineral scale deposition in downhole equipment and pipelines.
• Pulp & Paper Processing: Serves as a chelating agent in bleaching sequences to stabilize peroxides and control metal-ion catalyzed decomposition, improving pulp brightness.
• Textile Auxiliary: Prevents scale formation on machinery and fabric during dyeing and finishing processes, ensuring consistent color quality and fabric hand.
• Personal Care Products: Incorporated into formulations as a stabilizer and chelant to enhance the shelf-life and performance of products like shampoos and liquid soaps.
