Description

Tetradecasodium [[(Phosphonatomethyl)Imino]Bis[Ethylene[(Phosphonatomethyl)Imino]Ethylenenitrilobis(Methylene)]]Tetrakisphosphonate is a high-performance, multi-dentate chelating agent and scale inhibitor belonging to the class of amino polyphosphonates. Its complex molecular structure provides exceptional binding capacity for di- and trivalent metal ions, making it a critical component for preventing scale formation and corrosion in demanding industrial water systems. This product is essential for chemical suppliers, water treatment formulators, and industrial facilities requiring advanced sequestration technology. It is particularly valued in applications where conventional phosphonates are insufficient.

Application

• Industrial Water Treatment: Primary use as a high-efficiency scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis (RO) systems.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant in industrial and institutional cleaning products to inactivate water hardness ions.
• Pulp & Paper Processing: Used for peroxide stabilization and as a chelant in bleaching processes to improve efficiency and protect equipment.
• Textile Processing: Employed as a chelating agent in dyeing and bleaching baths to prevent metal-ion interference and ensure color fidelity.
• Oilfield Applications: Serves as a scale inhibitor in squeeze treatments and in produced water handling to prevent carbonate and sulfate scale deposition.
• Personal Care Products: Incorporated as a stabilizer and chelant in formulations such as shampoos and liquid soaps.
• Metal Surface Treatment: Used in electroplating and metal cleaning solutions to control water hardness and improve process stability.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can lead to caking or reduced efficacy.
