Description

Tetrapotassium [[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonate is a highly effective, water-soluble organic phosphonate compound. It matters as a powerful chelating and scale inhibition agent, offering superior performance in controlling mineral deposits and corrosion under demanding conditions. This product is essential for industrial water treatment, detergent formulations, and personal care applications where stability and efficacy are critical.

Application

• Industrial Water Treatment: Primary application as a highly effective scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Detergent & Cleaning Formulations: Acts as a builder and chelant to enhance cleaning power, prevent scale on surfaces and machinery, and improve surfactant performance.
• Personal Care Products: Used as a stabilizing and chelating agent in shampoos, liquid soaps, and other formulations to sequester metal ions that can degrade product quality.
• Pulp & Paper Processing: Employed to control scale formation and improve bleaching efficiency in pulp production.
• Textile & Dyeing Auxiliary: Serves as a dispersant and chelant to prevent metal-ion interference and ensure consistent dyeing results.
• Oilfield Applications: Used in scale squeeze treatments and as an additive in drilling fluids to control mineral scaling.

Quality Control

Our Tetrapotassium [[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, activity, and consistency. Certificates of Analysis (COA) documenting key parameters 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
