Description

Nonasodium Pentahydrogen [[(Phosphonatomethyl)Imino]Bis[Ethylene[(Phosphonatomethyl)Imino]Ethylenenitrilobis(Methylene)]]Tetrakisphosphonate is a high-performance, multi-dentate chelating agent 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 product is essential for industries requiring superior scale inhibition, corrosion control, and metal ion stabilization in aqueous systems.

Application

• Industrial Water Treatment: As a highly effective threshold inhibitor for scale prevention (calcium carbonate, calcium sulfate, barium sulfate) in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Chemicals: Used in scale squeeze treatments and as a component in drilling and completion fluids to control mineral scaling in downhole and production equipment.
• Pulp & Paper Manufacturing: Acts as a chelant in bleaching processes and as a dispersant to control deposits, improving pulp brightness and operational efficiency.
• Textile Processing: Serves as a sequestrant in dyeing and bleaching baths to prevent metal-ion interference, ensuring consistent color quality and fabric treatment.
• Detergent & Cleaning Formulations: Enhances the performance of industrial and institutional cleaners by chelating water hardness ions, improving surfactant efficacy and preventing soap scum.
• Personal Care Products: Used as a stabilizer and chelating agent in formulations to protect against metal-catalyzed degradation and improve shelf life.

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 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.
