Description

Diammonium Tetrahydrogen [Nitrilotris(Methylene)]Trisphosphonate is a high-performance phosphonate-based chelating agent and scale inhibitor. This compound is valued for its exceptional ability to sequester di- and trivalent metal ions, such as calcium and magnesium, under demanding conditions. It is primarily used by industrial water treatment, detergent formulation, and textile processing sectors to prevent scale formation, control corrosion, and enhance cleaning efficacy.

Application

• Industrial Water Treatment: A key component in cooling water and boiler water treatment programs for scale and corrosion inhibition.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to enhance the performance of detergents, dishwashing liquids, and industrial cleaners by inactivating water hardness ions.
• Textile Processing: Used as a peroxide stabilizer in bleaching baths and as a dispersant for dyeing processes to improve color uniformity.
• Pulp & Paper Industry: Employed in bleaching sequences to stabilize peroxides and chelate metal ions that can degrade pulp quality.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments to prevent mineral scale deposition in wellbores and production equipment.
• Personal Care Products: Incorporated in certain formulations as a chelating agent to improve stability and shelf life.

Quality Control

Our Diammonium Tetrahydrogen [Nitrilotris(Methylene)]Trisphosphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, pH, and impurity profiles. A Certificate of Analysis (COA) documenting purity, identity, and key physical-chemical parameters is 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
