Sodium Gluconate CAS 527-07-1
Sodium Gluconate (CAS 527-07-1) is the sodium salt of gluconic acid, white granules dissolving readily in water. Hydroxyl groups bind calcium, iron and other metal ions, so it chelates metal ions and slows cement hydration as a concrete set retarder and water reducer. Admixture plants use it in concrete. It also serves metal and glass cleaning, water treatment scale control, electroplating and textile printing. UATChem supplies grades in woven bags, ton bags and fiber drums, with COA, TDS and SDS on request.

What Sodium Gluconate Is
Sodium Gluconate is the sodium salt of gluconic acid, formula C6H11NaO7, CAS 527-07-1, sold as white granules. Hydroxyl groups next to the carboxylate hold multivalent metal ions in solution. It dissolves in water and biodegrades. In concrete it adsorbs on cement grains, delaying hydration, extending workability, reducing mix water, while in cleaning it keeps hardness and iron dissolved. UATChem supplies it, with assay on COA and TDS.
Concrete, Cleaning, Water Treatment and Food Uses
- Concrete admixture. It retards set, reduces mix water and extends workability in concrete and mortar.
- Metal and glass cleaning. It chelates hardness and iron in metal and glass bottle cleaners.
- Water treatment. It controls scale and corrosion by holding calcium and iron salts in solution.
- Electroplating, textile and food. It serves electroplating baths, textile printing and food use under E576.
