Description

Phosphonic Acid, 1,2-Ethanediylbis(Phosphonomethyl)Imino-3,1-Propanediylnitrilobis(Methylene)Tetrakis-, Sodium Salt is a high-performance, multi-dentate organic phosphonate compound. It serves as a highly effective scale and corrosion inhibitor and chelating agent across demanding industrial water systems. This product is essential for industries requiring superior water treatment, including cooling towers, boilers, oilfield operations, and detergent formulations, where it provides stability under harsh conditions.

Application

• Industrial Water Treatment: Primary application as a scale inhibitor for calcium carbonate, sulfate, and phosphate scales in cooling water and boiler feed water systems.
• Corrosion Control: Used to form protective films on metal surfaces (e.g., carbon steel, copper alloys) in closed-loop and open-recirculating cooling systems.
• Oilfield Chemistry: Employed in squeeze treatments and as an additive in drilling fluids to prevent mineral scale deposition in downhole formations and surface equipment.
• Detergent & Cleaning Formulations: Acts as a powerful builder and chelant to sequester hardness ions (Ca2+, Mg2+), enhancing cleaning efficiency in industrial and institutional cleaners.
• Pulp & Paper Processing: Used to control scale in digesters, washers, and bleach plants, and to chelate metal ions that can degrade pulp quality.
• Textile Processing: Prevents scale buildup on machinery and fabric, and acts as a dispersant for dyes and pigments.
• Metal Surface Treatment: Serves as a component in pickling and plating baths to control metal ions and improve surface finish.
• Personal Care Products: May be used in specific formulations as a chelating agent to stabilize products by binding trace metals.

Quality Control

Our Phosphonic Acid, 1,2-Ethanediylbis(Phosphonomethyl)Imino-3,1-Propanediylnitrilobis(Methylene)Tetrakis-, Sodium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent performance as a scale inhibitor and chelant. Key parameters such as active content, pH, density, and phosphonate concentration are verified. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory 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/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality. Keep away from incompatible materials.
