Used as a scale and corrosion inhibitor in water treatment systems, particularly in cooling towers and boilers. It prevents the formation of calcium and magnesium scale deposits by chelating metal ions. Also enhances the effectiveness of biocides and other inhibitors in industrial water systems. Applied in detergents and cleaning formulations to improve performance in hard water by sequestering metal ions. Provides stability in hydrogen peroxide-based bleaching systems in textile and paper industries. Exhibits good biodegradability compared to other phosphonates, making it suitable for applications requiring lower environmental impact.
