Description

Ethylenediamine-N,N'-Bis(Isopropylphos- Phonic Ac.) Hydrate is a specialized organophosphorus compound known for its excellent chelating and scale inhibition properties. This chemical is critical for industrial processes where control over metal ions and prevention of inorganic deposits is required for operational efficiency and equipment longevity. It is primarily utilized by manufacturers and formulators in the water treatment, detergent, and textile processing industries seeking high-performance additives.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Detergent & Cleaning Formulations: Serves as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions like calcium and magnesium.
• Textile Processing: Used as a chelating agent in dyeing and bleaching baths to prevent metal-ion interference and improve color fastness.
• Pulp & Paper Manufacturing: Employed to control metal ions during bleaching processes, protecting equipment and improving pulp brightness.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments to prevent carbonate and sulfate scale formation in wellbores and production equipment.
• Personal Care Products: Incorporated into formulations as a stabilizer and chelant to improve product shelf life and performance.
