Description

Octasodium Hexahydrogen [[(Phosphonatomethyl)Imino]Bis[Ethylene[(Phosphonatomethyl)Imino]Ethylenenitrilobis(Methylene)]]Tetrakisphosphonate is a high-performance, multi-dentate phosphonate chelating agent and scale inhibitor. Its complex molecular structure provides exceptional sequestration power for di- and trivalent metal ions, particularly calcium, magnesium, and iron, under demanding conditions. This product is essential for industries requiring robust water treatment, where it prevents scale formation, inhibits corrosion, and stabilizes formulations. Its superior threshold inhibition and compatibility make it a critical component in industrial cleaning, detergent formulations, and oilfield applications.

Application

• Industrial Water Treatment: Primary application as a high-efficiency 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 efficacy by inactivating water hardness ions and preventing soap scum.
• Oilfield Chemicals: Used in scale squeeze treatments and as an additive in drilling and completion fluids to control mineral scale deposition in wells and production equipment.
• Pulp & Paper Processing: Serves as a chelant in bleaching processes and as a dispersant to control deposits, improving pulp brightness and paper quality.
• Textile Processing: Prevents metal ion interference in dyeing and bleaching baths, ensuring consistent color and fabric quality.
• Personal Care Products: Incorporated into certain formulations as a stabilizer and chelating agent to protect product integrity.
• Industrial & Institutional (I&I) Cleaners: Key ingredient in heavy-duty acidic and alkaline cleaners for descaling and metal surface treatment.

Quality Control

Our Octasodium Hexahydrogen [[(Phosphonatomethyl)Imino]Bis[Ethylene[(Phosphonatomethyl)Imino]Ethylenenitrilobis(Methylene)]]Tetrakisphosphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets high-purity standards for industrial applications. Key parameters such as active content, pH, and phosphonate concentration are verified. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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. Store away from incompatible materials.
