Description

Decasodium hexahydrogen [ethane-1,2-diylbis[[(phosphonatomethyl)imino]ethane-2,1-diyl[(phosphonatomethyl)imino]ethane-2,1-diylnitrilobis(methylene)]]tetrakisphosphonate is a high-performance, multi-dentate chelating agent and scale inhibitor belonging to the class of aminophosphonates. Its primary value lies in its exceptional ability to sequester 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 industrial operations requiring superior water treatment, process stabilization, and scale and corrosion control.

Application

• Industrial Water Treatment: As a highly effective scale and corrosion inhibitor in cooling water systems, boiler water, and reverse osmosis (RO) membranes.
• Detergent & Cleaning Formulations: Acts as a powerful builder and chelant to enhance cleaning efficiency by inactivating water hardness ions in laundry and industrial cleaners.
• Pulp & Paper Processing: Used for peroxide stabilization and as a chelant in bleaching processes to improve brightness and protect equipment.
• Textile Processing: Employed in dyeing and bleaching baths to sequester metal ions that can cause shade variation or fabric degradation.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments and production systems to prevent mineral scale deposition.
• Personal Care Products: Incorporated as a stabilizing and chelating agent in formulations like shampoos and liquid soaps.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to minimize absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
