Description

Pentadecasodium hydrogen [ethane-1,2-diylbis[[(phosphonatomethyl)imino]ethane-2,1-diyl[(phosphonatomethyl)imino]ethane-2,1-diylnitrilobis(methylene)]]tetrakisphosphonate is a high-performance, multi-dentate phosphonate-based chelating agent and scale inhibitor. This compound is engineered to deliver superior sequestration of polyvalent metal ions, particularly calcium, magnesium, and iron, under demanding conditions. It is essential for industrial water treatment, detergent formulations, and processes requiring robust scale and corrosion control. Its unique polymeric structure provides exceptional threshold inhibition and thermal stability.

Application

• Industrial Water Treatment: Primary application as a highly effective 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 by inactivating water hardness ions.
• Pulp & Paper Processing: Used to control scale formation and stabilize hydrogen peroxide in bleaching applications.
• Textile Processing: Prevents metal ion interference during dyeing, bleaching, and finishing operations.
• Oilfield Chemicals: Employed in scale squeeze treatments and as a component in drilling fluids to control mineral deposition.
• Personal Care Products: Incorporated as a chelating agent in shampoos, soaps, and other formulations to improve stability and performance.

Quality Control

Our production of pentadecasodium phosphonate adheres to stringent quality management protocols. Every batch is analyzed to ensure consistent performance and purity, meeting the specifications required for industrial and formulation applications. Certificates of Analysis (COA) documenting key parameters such as active content, pH, and density are provided with each shipment to guarantee traceability and compliance.

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); ensure containers are kept sealed to prevent absorption of atmospheric moisture which may lead to caking or reduced efficacy.
