Description

Hexasodium Dihydrogen [Ethane-1,2-Diylbis[Nitrilobis(Methylene)]]Tetrakisphosphonate is a highly effective, multi-dentate chelating agent and scale inhibitor belonging to the aminophosphonate family. This compound is critical for controlling scale formation and sequestering problematic metal ions in complex aqueous systems where conventional phosphonates are insufficient. It is essential for industrial water treatment, detergent formulation, and textile processing where superior sequestration power and thermal stability are required.

Application

• Industrial Water Treatment: Primary application as a high-performance scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems, particularly effective against calcium carbonate, sulfate, and phosphate scales.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing surfactant efficiency and preventing inorganic salt deposition.
• Textile Processing: Used in bleaching, dyeing, and finishing baths to sequester metal ions that can cause catalytic damage to fibers and uneven dyeing.
• Pulp & Paper Industry: Employed in bleaching sequences (e.g., hydrogen peroxide bleaching) to chelate transition metals (Fe, Mn, Cu) that catalyze peroxide decomposition.
• Oilfield Chemicals: Component in scale squeeze treatments and production chemicals to prevent mineral scale deposition in downhole and topside equipment.
• Personal Care Products: Functions as a chelating agent in shampoos, soaps, and other formulations to stabilize products and improve clarity.
• Industrial Cleaning: Key ingredient in metal cleaning and electroplating solutions to control water hardness and prevent spotting.
• Agriculture: Used in certain fertilizer and micronutrient formulations to improve stability and bioavailability.

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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
