Description

Nonaammonium Hydrogen [[(Phosphonatomethyl)Imino]Bis[Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a high-performance, multi-dentate chelating agent belonging to the aminophosphonate chemical family. Its core value proposition lies in its exceptional ability to sequester and deactivate di- and trivalent metal ions, such as calcium, magnesium, iron, and copper, even under challenging conditions of high temperature and pH. This makes it a critical component for industries requiring superior scale inhibition, corrosion control, and metal ion stabilization. Key users include water treatment specialists, detergent formulators, and industrial cleaning chemical producers seeking to enhance product efficacy and process reliability.

Application

• Industrial Water Treatment: Primary application as a highly effective scale and corrosion inhibitor in cooling water systems, boiler water, and reverse osmosis membranes.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions and stabilizing bleach.
• Pulp & Paper Processing: Used for peroxide stabilization and as a chelant in bleaching stages to improve brightness and protect equipment.
• Textile Processing: Employed in bleaching, dyeing, and scouring baths to prevent metal-ion catalyzed degradation of fabrics and dyes.
• Oilfield Chemistry: Applied in scale squeeze treatments and as an additive in drilling fluids to control mineral scale deposition.
• Personal Care Products: Functions as a chelating agent in formulations like shampoos and liquid soaps to improve stability and clarity.
• Industrial & Institutional (I&I) Cleaners: Key ingredient in acidic, alkaline, and neutral cleaners for hard surface cleaning, providing superior sequestration.
• Metal Surface Treatment: Used in pickling and plating baths to control metal ions and improve surface finish quality.

Quality Control

Our production of Nonaammonium DTPMP adheres to a stringent quality management system to ensure batch-to-batch consistency and performance reliability. All materials undergo rigorous analytical testing, including assay by titration, identification (IR), and measurement of key physical parameters. Certificates of Analysis (COA) documenting purity, active content, pH, density, and color are provided with each shipment. We support compliance with relevant industry standards and can tailor specifications to meet specific customer requirements for applications in water treatment, detergents, and other industrial processes.

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 product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy. Keep away from incompatible materials such as strong oxidizing agents.
