Description

Hexapotassium Tetrahydrogen [[(Phosphonatomethyl)Imino]Bis[Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a highly effective, multi-dentate chelating agent belonging to the aminophosphonate 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 industries requiring superior scale inhibition, corrosion control, and metal ion stabilization in aqueous systems. Key users include water treatment formulators, industrial cleaning specialists, and detergent manufacturers seeking high-performance, phosphorus-based additives.

Application

• Industrial Water Treatment: As a powerful scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Detergent & Cleaning Formulations: Acts as a superior builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions.
• Pulp & Paper Processing: Used to control metal ions that can catalyze peroxide decomposition and cause brightness reversion.
• Textile Processing: Prevents scale formation on machinery and ensures consistent dyeing and finishing by chelating interfering metal ions.
• Oilfield Applications: Employed in scale squeeze treatments and as an additive in drilling fluids to control mineral scaling.
• Personal Care Products: Functions as a chelating agent in formulations to stabilize products and improve efficacy.
• Industrial & Institutional (I&I) Cleaners: A key component in acidic, alkaline, and neutral cleaners for hard surface cleaning and metal pretreatment.

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 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.
