Description

Dodecapotassium [Ethane-1,2-Diylbis[[(Phosphonatomethyl)Imino]Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a highly water-soluble, multi-dentate chelating agent belonging to the aminopolyphosphonate family. Its primary value lies in its exceptional ability to sequester and deactivate di- and trivalent metal ions, such as calcium, magnesium, and iron, across a wide pH range. This product is essential for industrial processes where scale inhibition, metal ion control, and dispersion are critical. Key industries that rely on this high-performance chelant include water treatment, detergent formulation, textile processing, and pulp & paper manufacturing.

Application

• Industrial Water Treatment: Acts as a powerful scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems by sequestering hardness ions.
• Detergent & Cleaning Formulations: Serves as a superior builder and chelating agent to enhance cleaning efficiency by inactivating metal ions in water that interfere with surfactants.
• Textile Processing: Used in bleaching, dyeing, and scouring baths to prevent metal-ion catalyzed degradation of fibers and dyes, ensuring consistent color and fabric quality.
• Pulp & Paper Industry: Employed as a stabilizer in hydrogen peroxide bleaching to deactivate transition metal ions, improving bleaching efficiency and pulp brightness.
• Personal Care Products: Functions as a chelant in shampoos, liquid soaps, and other formulations to enhance stability and shelf-life by binding trace metals.
• Oilfield Applications: Used in scale squeeze treatments and as an additive in drilling fluids to control scale formation and improve fluid performance.
• Industrial & Institutional Cleaners: A key component in heavy-duty cleaners for food processing, dairy, and transportation for effective soil removal and rinse aid properties.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy. Keep away from incompatible materials such as strong oxidizing agents.
