Description

Tetrapotassium [(Butylimino)Bis(Methylene)]Bisphosphonate is a high-purity, water-soluble organophosphonate compound. It serves as a highly effective chelating and scale inhibition agent, crucial for controlling mineral deposits in industrial water systems. This product is essential for manufacturers and formulators in the water treatment, detergent, and personal care industries seeking reliable performance and supply chain stability.

Application

• Industrial Water Treatment: Primary application as a superior scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a builder and chelant to enhance cleaning power by sequestering calcium and magnesium ions, preventing soap scum and improving surfactant efficiency.
• Personal Care Products: Used in formulations such as shampoos and liquid soaps for its chelating properties, improving stability and clarity.
• Pulp & Paper Processing: Employed to control scale formation and as a dispersant for pigments and fillers.
• Textile & Dyeing Auxiliary: Helps in sequestering metal ions in process water to prevent interference with dyes and finishing agents.
• Oilfield Applications: Used in scale squeeze treatments and as a component in drilling fluids to control mineral scaling.

Quality Control

Our Tetrapotassium [(Butylimino)Bis(Methylene)]Bisphosphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, pH, and impurity profiles. Certificates of Analysis (COA) are provided and available upon request, confirming compliance with relevant industry standards.

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); ensure the container is securely sealed after each use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
