Sodium Gluconate
Sodium Gluconate is a white, crystalline powder derived from gluconic acid and sodium salt. It is highly water-soluble, biodegradable, and non-toxic, widely used as a chelating agent, sequestrant, and buffering agent across various industries. Sodium Gluconate is favored for its excellent ability to bind metal ions, improve cleaning efficiency, and stabilize formulations. It finds extensive applications in construction, water treatment, food, pharmaceuticals, cosmetics, and textiles.
