Description

Hexadecapotassium [2,5,8,11,14,17-Hexakis(Phosphonatomethyl)-2,5,8,11,14,17-Hexaazaoctadecane-1,18-Diyl]Bisphosphonate is a highly water-soluble, multi-dentate chelating agent belonging to the class of polyaminopolyphosphonates. Its core value proposition lies in its exceptional ability to sequester and deactivate multivalent metal ions, such as calcium, magnesium, and iron, across a wide pH range. This compound is essential for industries requiring advanced scale inhibition, metal passivation, and high-performance cleaning, particularly in water treatment, detergent formulations, and industrial process chemistry.

Application

• Industrial Water Treatment: Acts as a superior threshold scale inhibitor and dispersant for calcium carbonate, sulfate, and phosphate scales in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Serves as a powerful builder and sequestrant in industrial and institutional cleaning products, enhancing surfactant efficiency and preventing soap scum and mineral deposits.
• Pulp & Paper Processing: Used as a chelant in bleaching processes and to control metal-ion catalyzed decomposition of hydrogen peroxide, improving brightness and process efficiency.
• Textile Processing: Prevents adverse effects of hard water in dyeing and finishing baths, ensuring consistent color quality and fabric handling.
• Oilfield Applications: Employed in scale squeeze treatments and as a component in drilling fluids to control mineral scaling in downhole and production equipment.
• Personal Care Products: Functions as a stabilizing and chelating agent in formulations such as shampoos and liquid soaps to improve clarity and shelf-life.
• Metal Surface Treatment: Used in metal cleaning and plating baths to sequester interfering ions and improve surface quality.
• Agricultural Chemicals: Can be used as a stabilizer and compatibility agent in certain pesticide and fertilizer formulations.

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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
