Sodium gluconate is a compound with formula NaC6H11O7. It is the sodium salt of gluconic acid. Its E number is E576. 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 powder that is very soluble in water.

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.

Uses for Sodium Gluconate:

In the field of medicine, it can maintain the balance of acid and alkali in the human body, and recover the normal operation of nerves.

It can be used in the prevention and cure of the syndrome for low sodium.

It can be used as a water quality stabilizer because it has excellent inhibiting capacity to scale.

Used as surface cleaning agent for metals

Used as cleaning agent of glass bottles

It also can be used as water reducing agent and retarder in the building industry. Sodium gluconate is also an efficient set retarder and a good plasticiser & water reducer for concrete, cement, mortar and gypsum.

Industrial Applications of sodium gluconate

Sodium gluconate is used in electroplating and metal finishing because of its strong affinity for metal ions. Acting as a sequestrant it stabilises the solution preventing impurities from triggering undesirable reactions in the bath. The chelation properties of gluconate assist in the deterioration of the anode thus increasing plating bath efficiency. Gluconate can be used in copper, zinc and cadmium plating baths for brightening and increasing luster.

Sodium gluconate is used in agrochemicals and in particular fertilisers. It helps plants and crops to absorb necessary minerals from the soil.

It is used in the paper and pulp industries where it chelates out metallic ions which cause problems in the peroxide and hydrosulphite bleaching processes.

Sodium gluconate in Construction Industry

Sodium gluconate is used as a concrete admix. It offers several benefits including improved workability, retarding setting times, reducing water, improved freeze-thawing resistance, reduced bleeding, cracking and dry shrinkage. When added at a level of 0.3% sodium gluconate can retard setting time of cement to over 16 hours depending on ratio of water and cement, temperature etc. As it acts as a corrosion inhibitor it helps to protect iron bars used in concrete from corrosion.

Sodium gluconate as a corrosion inhibitor

When sodium gluconate is present in water above 200ppm it protects steel and copper from corrosion. Water pipes and tanks composed of these metals are prone to corrosion and pitting caused by dissolved oxygen in the circulation water. This leads to cavitation and degradation of the equipment. The sodium gluconate reacts with the metal producing a protective film of the gluconate salt of the metal eliminating the possibility of the dissolved oxygen to come into direct contact with the metal.

In addition sodium gluconate is added to deicing compounds like salt and calcium chloride which are corrosive. This helps protect metal surfaces from being attacked by the salts but not deterring from the salt's ability to dissolve ice and snow.

Sodium gluconate in the cleaning industry

Sodium gluconate is commonly found in many household and industrial cleaners. This is because on its multi functionality. It acts as a chelating agent, a sequestering agent, a builder and a redeposition agent. In alkaline cleaners like dishwasher detergents and degreasers it prevents hard water ions (magnesium and calcium) interfering with the alkalies and allows the cleaner to perform to its maximum ability.

Sodium gluconate helps as a soil remover for laundry detergents as it breaks the calcium bond holding the dirt to the fabric and further prevents the soil redepositing onto the fabric again.

Sodium gluconate helps to protect metals like stainless steel when strong caustic based cleaners are used. It helps to break down scale, milkstone and beerstone. As a result it finds application in many acid based cleaners especially those formulated for use in the food industry.

 Description:

Sodium gluconate - chemical compound, salt of sodium and gluconic acid, colorless crystals, soluble in water, food additive E576.

Application:

In industrial detergents

Sodium gluconate and gluconic acid are used as complexing agents for bivalent or trivalent metal cations in industrial alkaline detergents. They are particularly effective in this application, even when compared to agents such as NTA and EDTA. Gluconic acid and sodium gluconate are commonly used in liquid formulations in combination with other ingredients such as surfactants, sodium hydroxide, sodium silicate, and phosphates.

Additive to concrete and building mixtures

Sodium gluconate slows down the setting of concrete, lowers water content and improves plasticity even at low dosages. Its use contributes to the production of concrete with increased strength.

Cement additive for the oil industry

Sodium gluconate is used in the oil industry for cementing boreholes.

Metallurgical applications

Sodium gluconate is used in steel making and especially in aluminum production.

Application in the food industry

Sodium gluconate in the food industry is a complexing agent and flavor enhancer.
