China and India are the leading exporters of Tetrasodium etidronate (CAS 3794-83-0), accounting for the majority of global export volume in recent years, while the United States, Germany, and South Korea represent the largest importers. Import volumes into the EU and North America have remained relatively stable since 2022, with modest growth observed in Southeast Asian imports—coinciding with moderate upward pressure on Tetrasodium etidronate prices amid tightening supply chain logistics.
Tetrasodium etidronate is a white, crystalline, hygroscopic solid with no characteristic odor and low volatility; it is highly water-soluble and typically handled as a hydrated powder or aqueous solution. It is the tetrasodium salt of etidronic acid (1-hydroxyethylidene-1,1-diphosphonic acid), classified as an organophosphonic acid derivative. Primarily used as a chelating agent and scale inhibitor, it sequesters multivalent metal ions such as calcium, magnesium, iron, and copper. Its main industrial applications include water treatment (e.g., boiler and cooling water systems), detergents and cleaning formulations, and personal care products (e.g., shampoos and cosmetics) to stabilize active ingredients and prevent precipitation. It also serves in metal surface treatment and as a stabilizer in textile and pulp/paper processing.
