Description

Disodium Tetrahydrogen [Nitrilotris(Methylene)]Trisphosphonate is a highly effective 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, magnesium, and iron, under demanding conditions. It is a critical component for industrial water treatment, oilfield operations, and detergent formulations where control of scale and corrosion is paramount.

Application

• Industrial Water Treatment: Primary application as a threshold scale inhibitor and dispersant in cooling towers, boilers, and reverse osmosis systems to prevent calcium carbonate and sulfate scales.
• Oilfield Chemicals: Used in drilling fluids, completion brines, and squeeze treatments to control scale formation in downhole equipment and enhance oil recovery.
• Detergent & Cleaning Formulations: Acts as a builder and chelant to inactivate water hardness ions, improving surfactant efficiency and preventing inorganic salt deposits.
• Pulp & Paper Processing: Serves as a chelating agent in bleaching sequences to deactivate transition metal ions that catalyze cellulose degradation.
• Textile Processing: Utilized as a stabilizer in peroxide bleaching baths and as a dispersant to prevent metal-ion-induced fabric damage.
• Personal Care Products: Incorporated as a stabilizing and sequestering agent in certain cosmetic and personal care formulations.

Quality Control

Our Disodium Tetrahydrogen [Nitrilotris(Methylene)]Trisphosphonate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with every shipment to guarantee compliance with your technical requirements.

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 the container is kept tightly sealed to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
