Description

Hexaammonium [Nitrilotris(Methylene)]Trisphosphonate is a highly effective, water-soluble aminophosphonate 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, even under demanding alkaline conditions. It is a critical component for industrial water treatment, detergent formulations, and textile processing, where it prevents scale formation, stabilizes bleaches, and enhances cleaning efficiency. Global manufacturers and chemical processors rely on its consistent performance to maintain system integrity and operational efficiency.

Application

• Industrial Water Treatment: Primary application as a highly effective scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Detergent & Cleaning Formulations: Acts as a builder and bleach stabilizer, enhancing the performance of peroxygen bleaches and preventing metal-ion catalyzed decomposition in laundry and dishwashing products.
• Textile Processing: Used in bleaching and dyeing baths to sequester metal ions that can cause fabric degradation, spots, or uneven dyeing.
• Pulp & Paper Industry: Employed in bleaching sequences (e.g., hydrogen peroxide bleaching) to chelate transition metals and improve bleaching efficiency while protecting cellulose fibers.
• 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 Hexaammonium [Nitrilotris(Methylene)]Trisphosphonate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, pH, and impurity profiles. Certificates of Analysis (COA) documenting purity, identity, and performance-related parameters are available upon request to support your quality assurance and regulatory compliance 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). This product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed after opening to prevent absorption of atmospheric moisture which may lead to caking or reduced efficacy.
