(1-Hydroxyethylidene)bis-phosphonic acid tetrasodium salt Cas 3794-83-0

Industrial Water Treatment: Scale Inhibitors and Corrosion Inhibitors—utilized in circulating cooling water systems, boiler water, and central air conditioning cooling water to inhibit the formation of calcium carbonate and calcium sulfate scale, while simultaneously providing corrosion inhibition for carbon steel and copper.
Daily Chemicals & Detergent Industry: Laundry detergents, dishwashing liquids, and industrial cleaning agents—serving as chelating and water-softening agents to complex calcium and magnesium ions, thereby enhancing cleaning efficacy and preventing soil redeposition.
Electroplating Industry: Electroplating bath complexing agents and stabilizers—improving plating uniformity, enhancing bath performance, and preventing the precipitation of metal ions.
Textile Printing & Dyeing: Chelating dispersants for printing and dyeing—softening water quality, preventing dye precipitation and color spots, and improving color fastness.
