Sodium gluconate is a chemical compound of sodium from the group of carboxylic acid salts and the sodium salt of gluconic acid.

Sodium gluconate is white and almost odorless solid that is easily soluble in water. The compound decomposes at temperatures above about 200 °C. The substance resists hydrolysis even for short periods at high temperatures and pH values.

What is Sodium Gluconate used for?

Sodium gluconate is a good chelating agent at alkaline pH, with better chelating properties than EDTA, NTA and other chelating agents. It has a wide range of industrial uses, including textile dyeing, water treatment and as a cleaning agent for glass bottles. It is also used as a rust remover in metallurgy and as an additive in cement. The cleaning effect of sodium gluconate is based on the formation of metal ion complexes, which are stable in a neutral and above all alkaline environment. This is used for deoxidizing steel, copper and its alloys, for degreasing or etching aluminum and for dezincification of workpieces. At 95 to 100 ° C, paint and varnish layers are removed. It is used in foods to mask the bitter aftertaste of sweeteners, to improve the swellability and solubility of dairy products, and as an electrolyte regenerator.

The compound is considered harmless.
