Description

1-Hydroxyethanediphosphonic Acid Potassium Salt is a highly effective organophosphorus compound widely used as a scale and corrosion inhibitor. This product matters for its superior chelating and threshold inhibition properties, which are critical for maintaining system efficiency and longevity in industrial water treatment. It is primarily needed by professionals in the water treatment, detergent, and textile industries seeking reliable performance under demanding conditions.

Application

• Industrial Water Treatment: A key component in cooling water and boiler water treatment formulations to prevent scale formation (e.g., calcium carbonate, calcium sulfate) and inhibit corrosion of metal surfaces.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing the cleaning efficiency of soaps and detergents.
• Textile Processing: Used as a stabilizer and chelating agent in peroxide bleaching baths and dyeing processes to improve color fastness and fabric quality.
• Pulp & Paper Industry: Employed in bleaching sequences to stabilize peroxides and chelate metal ions that can catalyze fiber degradation.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments and production systems to prevent mineral scale deposition in wells and pipelines.
• Personal Care Products: Incorporated in certain formulations as a chelating agent to improve stability and shelf-life.

Quality Control

Our 1-Hydroxyethanediphosphonic Acid Potassium Salt is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and active content are available upon request to support your quality assurance protocols.

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 material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which may affect product quality.
