Description

Tetraammonium Dihydrogen [Nitrilotris(Methylene)]Trisphosphonate is a high-performance, water-soluble phosphonate compound. It serves as a highly effective chelating agent and scale inhibitor, crucial for controlling mineral deposits in industrial water systems. This product is essential for formulators and manufacturers in the water treatment, detergent, and textile processing industries seeking reliable sequestration and dispersion performance.

Application

• Industrial Water Treatment: Primary application as a scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions (Ca²⁺, Mg²⁺).
• Textile Processing: Used as a peroxide stabilizer and sequestrant in bleaching and dyeing baths to improve process uniformity and fabric quality.
• Pulp & Paper Industry: Employed in bleaching sequences to stabilize peroxides and chelate metal ions that can degrade cellulose.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments and production systems to prevent carbonate and sulfate scale formation.
• Personal Care Products: Incorporated into certain formulations as a chelating agent to improve stability and efficacy.
• Industrial Cleaners: Key component in acid-based and alkaline cleaners for descaling and metal surface treatment.
• Agriculture: Used in certain fertilizer and micronutrient formulations to improve nutrient availability.

Quality Control

Our Tetraammonium Dihydrogen [Nitrilotris(Methylene)]Trisphosphonate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with relevant industry specifications. A comprehensive Certificate of Analysis (COA) detailing assay, active content, pH, density, and other critical parameters is provided with every shipment.

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 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.
