Description

Hexaammonium Tetrahydrogen [[(Phosphonatomethyl)Imino]Bis[Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a highly effective, multi-dentate chelating agent and scale inhibitor belonging to the aminophosphonate chemical family. Its primary value lies in its exceptional ability to sequester and deactivate di- and trivalent metal ions, such as calcium, magnesium, and iron, even under challenging conditions of high temperature and pH. This makes it a critical component for industries requiring robust water treatment, where it prevents scale formation, inhibits corrosion, and stabilizes process streams. Key users include water treatment formulators, industrial cleaning specialists, and producers in the textile, pulp & paper, and oilfield sectors.

Application

• Industrial Water Treatment: As a high-performance threshold scale inhibitor and dispersant in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a powerful builder and chelant in industrial and institutional cleaning products to enhance surfactant efficiency and prevent soap scum.
• Textile Processing: Used in bleaching and dyeing baths to sequester metal ions that can cause fabric discoloration or degrade peroxide bleaches.
• Pulp & Paper Manufacturing: Prevents scale deposition on machinery and improves bleaching efficiency by chelating transition metals.
• Oilfield Applications: Serves as a scale squeeze treatment and additive in drilling fluids to control mineral scaling in wells and production equipment.
• Industrial Cleaning: Key ingredient in acid-based and alkaline cleaners for metal surface treatment, circuit board etching, and dairy/brewery cleaning-in-place (CIP) systems.
• Personal Care: Used in select formulations as a chelating agent to stabilize products and enhance preservative efficacy.

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.
