Description

Hexasodium [[[2-[[[Bis(Hydroxymethyl)Phosphino]Methyl](Phosphonatomethyl)Amino]Ethyl]Imino]Bis(Methylene)]Bisphosphonate is a highly effective, multi-functional phosphonate-based chelating agent and scale inhibitor. Its complex molecular structure provides superior sequestration of metal ions, particularly calcium, magnesium, and iron, making it a critical component in water treatment and industrial cleaning formulations. This compound is essential for industries requiring robust control over scale formation, corrosion, and metal-induced degradation in aqueous systems. Its high water solubility and thermal stability under alkaline conditions offer significant performance advantages in demanding applications.

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: Key builder and sequestrant in industrial and institutional cleaning products, enhancing efficacy in hard water.
• Pulp & Paper Processing: Used as a chelant in bleaching processes and to control metal ions that can affect pulp quality and paper brightness.
• Textile Processing: Employed in dyeing and bleaching baths to sequester metal ions that can cause shade variation or fabric damage.
• Oilfield Chemicals: Component in scale squeeze treatments and downhole scale control formulations to prevent mineral scale deposition.
• Personal Care Products: Acts as a chelating agent in shampoos, soaps, and other formulations to improve stability and shelf life.
• Metal Surface Treatment: Used in metal cleaning and plating baths to control water hardness and prevent precipitation.

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 can lead to caking or reduced efficacy. Keep away from incompatible materials.
