Description

Cyclohexane-1,2-Diylbis[Nitrilobis(Methylene)]]Tetrakisphosphonic Acid, Sodium Salt is a high-purity, water-soluble chelating agent belonging to the class of polyaminophosphonates. This compound is valued for its exceptional ability to sequester and deactivate di- and trivalent metal ions, such as calcium, magnesium, and iron, even under challenging conditions. It is a critical raw material for industrial water treatment, detergent formulations, and scale inhibition processes where superior chelation performance and thermal stability are required.

Application

• Industrial Water Treatment: Primary application as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Key builder and sequestrant in heavy-duty industrial and institutional cleaners, enhancing surfactant efficiency and preventing soap scum.
• Pulp & Paper Processing: Used to control metal ions that can catalyze peroxide decomposition and cause brightness reversion in pulp bleaching.
• Textile Processing: Acts as a chelant in dyeing and scouring baths to prevent metal-ion interference and ensure consistent color quality.
• Oilfield Chemicals: Employed in scale squeeze treatments and as a component in drilling fluids to control carbonate and sulfate scale formation.
• Personal Care Products: Incorporated as a stabilizing agent in formulations such as shampoos and liquid soaps to improve shelf-life and clarity.
• Industrial Cleaning: Effective in acid cleaning formulations for metal surfaces and equipment to control ferric iron and prevent secondary precipitation.
• Agricultural Chemicals: Used as a stabilizer and compatibility agent in certain pesticide and micronutrient fertilizer formulations.

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 product 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 flowability.
