Description

Hexasodium Hexahydrogen [Ethane-1,2-Diylbis[[(Phosphonatomethyl)Imino]Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a highly effective, multi-dentate chelating agent and scale inhibitor belonging to the aminophosphonate family. Its complex molecular structure provides exceptional binding affinity for di- and trivalent metal ions, such as calcium, magnesium, and iron, making it a critical component for controlling water hardness and preventing mineral scale formation. This product is essential for industrial water treatment, detergent formulation, and textile processing where superior sequestration and dispersion performance are required under demanding conditions.

Application

• Industrial Water Treatment: Primary application as a high-performance scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis (RO) systems.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions.
• Textile Processing: Used in bleaching, dyeing, and finishing baths to prevent metal-ion interference and improve process uniformity.
• Pulp & Paper Industry: Employed as a chelant in bleaching processes (e.g., hydrogen peroxide stabilization) and to control scale in paper machines.
• Oilfield Chemicals: Incorporated into scale inhibitor squeezes and water flood treatments to prevent carbonate and sulfate scale deposition in wells and pipelines.
• Personal Care Products: Functions as a chelating agent in shampoos, soaps, and other formulations to improve stability and shelf life.
• Metal Surface Treatment: Used in electroplating and metal cleaning solutions to control water hardness and improve finish quality.

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 may lead to caking or reduced efficacy.
