Description

Nonaammonium Pentahydrogen [[(Phosphonatomethyl)Imino]Bis[Ethylene[(Phosphonatomethyl)Imino]Ethylenenitrilobis(Methylene)]]Tetrakisphosphonate is a high-performance, multi-dentate chelating agent belonging to the aminophosphonate chemical class. Its complex molecular structure provides exceptional sequestering power for di- and trivalent metal ions, making it a critical component in applications demanding superior scale and corrosion inhibition. This product is essential for industrial water treatment, detergent formulation, and textile processing where stable chelation under harsh conditions is required. We supply this specialty chemical to meet the stringent quality and reliability needs of the global B2B market.

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 powerful builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing surfactant efficiency and preventing scale deposition.
• Textile Processing: Used in bleaching, dyeing, and finishing baths to sequester metal ions that can cause fabric discoloration or degrade peroxide bleaches.
• Pulp & Paper Manufacturing: Prevents scale formation in digesters and bleach plants, and chelates metals that catalyze the decomposition of bleaching chemicals.
• Oilfield Chemicals: Employed in scale squeeze treatments and as a component in drilling fluids to control mineral scaling in downhole and production equipment.
• Personal Care Products: Incorporated as a chelating agent in shampoos, liquid soaps, and other formulations to improve stability and clarity.
• Metal Surface Treatment: Used in electroplating and metal cleaning solutions to control water hardness and prevent precipitation on metal surfaces.
• Agricultural Chemicals: Can be used as a stabilizer and chelating agent in certain pesticide and micronutrient fertilizer formulations.

Storage

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