Description

Octapotassium Tetrahydrogen [Ethane-1,2-Diylbis[[(Phosphonatomethyl)Imino]Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a high-performance, multi-dentate chelating agent belonging to the aminophosphonate chemical family. This compound is engineered for superior sequestration and stabilization of metal ions, particularly in demanding aqueous systems where scale and corrosion control are critical. It is an essential raw material for formulators in the water treatment, detergent, and personal care industries, where its exceptional chelation power and thermal stability provide a significant performance advantage.

Application

• Industrial Water Treatment: Primary application as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems, particularly effective against calcium, magnesium, and iron scales.
• Detergent & Cleaning Formulations: Used as a builder and chelant in heavy-duty industrial and institutional cleaners, liquid soaps, and dishwashing detergents to enhance cleaning efficiency by inactivating water hardness ions.
• Personal Care Products: Acts as a stabilizing and chelating agent in shampoos, liquid soaps, and other cosmetic formulations to improve shelf life and product clarity.
• Pulp & Paper Processing: Employed in bleaching and pulping processes to chelate transition metal ions that can catalyze the degradation of cellulose and bleach chemicals.
• Textile Processing: Used in dyeing and finishing baths to prevent metal-ion interference, ensuring consistent color quality and improving process efficiency.
• Oilfield Chemicals: Component in scale inhibitor formulations for squeeze treatments and production chemicals to prevent mineral scale deposition in wells and pipelines.

Quality Control

Our production of Octapotassium EDTMP adheres to stringent quality management protocols to ensure batch-to-batch consistency and high performance. Each lot undergoes comprehensive analysis, including assay (chelation value), pH, solids content, and ionic impurity profiling. A Certificate of Analysis (COA) documenting these results is provided with every shipment. We support compliance with relevant industry standards, including those for water treatment chemicals and detergent ingredients.

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 may lead to caking or reduced efficacy.
