Description

Octaammonium Octahydrogen [2,5,8,11,14,17-Hexakis(Phosphonatomethyl)-2,5,8,11,14,17-Hexaazaoctadecane-1,18-Diyl]Bisphosphonate is a highly functionalized, multi-dentate chelating agent belonging to the class of polyaminopolyphosphonates. This compound is engineered for superior sequestration and stabilization of metal ions across a wide pH range, making it a critical performance additive in demanding industrial processes. It is primarily utilized by formulators and manufacturers in the water treatment, detergent, and personal care industries where effective scale inhibition and metal ion control are paramount.

Application

• Industrial Water Treatment: Acts as a high-performance scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems, particularly effective against calcium, magnesium, and transition metal scales.
• Detergent & Cleaning Formulations: Serves as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions and stabilizing bleach in heavy-duty laundry and dishwashing products.
• Personal Care Products: Used as a chelating agent in shampoos, soaps, and cosmetic formulations to improve stability and shelf-life by binding trace metal impurities that can catalyze degradation.
• Pulp & Paper Processing: Functions as a stabilizer in hydrogen peroxide bleaching and as a dispersant for controlling metal ion interference, improving brightness and pulp quality.
• Textile & Leather Processing: Employed in dyeing and finishing baths to prevent metal-ion-induced shade variation and to improve the quality of peroxide bleaching processes.
• Oilfield Applications: Utilized in scale squeeze treatments and as an additive in drilling fluids to control scale formation and stabilize fluids under high-temperature, high-salinity conditions.
