Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Phosphono-.Omega.-Hydroxy- is a specialized organophosphorus compound featuring a polyether backbone terminated with phosphonic acid and hydroxyl functional groups. This unique bifunctional structure makes it a highly effective chelating agent, scale inhibitor, and dispersant in demanding aqueous systems. It is primarily utilized in industries where controlling metal ion precipitation and preventing mineral scale is critical for operational efficiency and equipment longevity.

Application

• Industrial Water Treatment: As a key component in cooling water and boiler water treatment formulations to inhibit calcium carbonate, calcium sulfate, and barium sulfate scale.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing the cleaning efficacy of soaps and detergents.
• Pulp & Paper Processing: Used as a dispersant and chelant in bleaching processes and to control scale in digesters and paper machines.
• Textile Auxiliary: Serves as a stabilizer and sequestering agent in peroxide bleaching baths and dyeing processes.
• Oilfield Chemicals: Employed in scale squeeze treatments and as an additive in drilling fluids to prevent mineral deposition in wells and pipelines.
• Personal Care Products: Functions as a chelating agent in shampoos, liquid soaps, and other formulations to improve stability and performance.

Quality Control

Our production of Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Phosphono-.Omega.-Hydroxy- adheres to stringent quality management protocols. Each batch undergoes rigorous testing to ensure consistent performance as a scale inhibitor and dispersant, with key parameters including active content, pH, density, and phosphorus content monitored. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture, which may affect product performance.
