glucono delta lactone GDL CAS NO.90-80-2

Sodium gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. It is a white to tan, granular to fine, crystalline powder, very soluble in water. Non corrosive, non-toxic and readily biodegradable (98 % after 2 days), sodium gluconate is more and more appreciated as chelating agent.

 

The outstanding property of sodium gluconate is its excellent chelating power, especially in alkaline and concentrated alkaline solutions. It forms stable chelates with calcium, iron, copper, aluminium and other heavy metals, and in this respect, it surpasses all other chelating agents, such as EDTA, NTA and related compounds.

 

Aqueous solutions of sodium gluconate are resistant to oxidation and reduction, even at high temperatures. However, it is easily degraded biologically (98 % after 2 days), and thus presents no wastewater problem.

 

Sodium gluconate is also a highly efficient set retarder and a good plasticiser / water reducer for concrete, mortar and gypsum.

 

And last but not least, it has the property to inhibit bitterness in foodstuffs.

Sodium Gluconate is a compound with formula NaC6H11O7. It is the sodium salt of gluconic acid. It has the E number of E576 which is a code for chemicals which can be used as food additives for use within the European Union and Switzerland (the "E" stands for "Europe"). Sodium Gluconate is widely used in textile dyeing, printing and metal surface water treatment. It is also used as a chelating agent, a steel surface cleaning agent, a cleaning agent for glass bottles, and as a chelating agent for cement, plating and alumina dyeing industries. It is a white colorless powder that is very soluble in water.
