  • Applications

    Sodium 3,4,5,6-tetrahydroxyoxane-2-carboxylate (CAS 9005-38-3), commonly known as sodium gluconate, is widely used as a gentle chelating/sequestering agent in household and industrial cleaners, where it binds calcium and other metal ions to improve detergency and inhibit scale formation. It is also employed as a set-retarding and modest water-reducing admixture in cement and concrete to improve workability and control hydration. In cosmetics and personal care, it acts as a humectant and formulation stabilizer, helping maintain moisture and product stability. In metal finishing and electronics-related cleaning and plating processes, it serves as a complexing agent that supports uniform deposition and effective surface cleaning. In agriculture and fertilizer formulations, it may chelate micronutrients to enhance their availability to plants.
