Description

Undecapotassium Hydrogen [Ethane-1,2-Diylbis[[(Phosphonatomethyl)Imino]Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a highly effective, multi-dentate chelating agent and scale inhibitor belonging to the class of phosphonate compounds. Its primary value lies in its exceptional ability to sequester di- and trivalent metal ions, such as calcium, magnesium, and iron, under demanding conditions. This makes it a critical component for industries requiring superior water treatment, process stabilization, and mineral scale prevention. Key users include manufacturers of industrial cleaning formulations, water treatment chemicals, and detergent builders.

Application

• Industrial Water Treatment: As a high-performance scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficiency and prevent inorganic salt deposition.
• Pulp & Paper Processing: Used for peroxide stabilization and as a chelant in bleaching processes to improve efficiency and protect equipment.
• Textile Processing: Serves as a stabilizer and sequestrant in dyeing and bleaching baths to ensure consistent color and fabric quality.
• Oilfield Applications: Employed in scale squeeze treatments and as an additive in drilling fluids to control mineral scaling.
• Industrial & Institutional (I&I) Cleaners: A key ingredient in acidic, alkaline, and neutral cleaners for hard surface cleaning and dairy/brewery CIP systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
