Sodium gluconate, also known as the sodium salt of gluconic acid, is an organic substance with the chemical formula C6H11NaO7. It is a white powder, non-toxic, and good in thermal stability. So it is very soluble in water, slightly soluble in alcohol, insoluble in ether. Moreover, sodium gluconate always plays an important role in many fields, such as construction industry, textile printing and dyeing, food industry, medical industry, electroplating and film manufacturing and so on. Its application prospect is very broad.

What is Sodium Gluconate Used for?
As we all know, Kingsun sodium gluconate 98% min can be widely used in different industries, such as concrete, soap, food, medical, cosmetics, toothpaste, etc. You can check the following applications of sodium gluconate powder.
Sodium Gluconate for Construction Industry
For construction industry, sodium gluconate can be used as concrete retarder admixture and water reducing agent. Besides, adding a certain amount of sodium gluconate 98% min to the cement, which can increase the plasticity and strength of the concrete. It can also delay the initial and final solidification time of the concrete.
(1) Used as concrete retarder admixture . It can delay the setting time of concrete, moreover, it can extend the working time of concrete from a few hours to a few days without compromising strength. When you need to place concrete for a long time or the weather is hot, this is an advantage. As a concrete retarder, sodium gluconate retarder has many advantages in the construction industry.
- By using sodium gluconate, the Water to Cement (W/C) ratio can be reduced, which increases the strength of the concrete and forms a high-quality type of concrete.
- Large and heavyweight perfusion construction engineerings are very difficult. Due to the addition of sodium gluconate, the operability of concrete is improved, the setting time is delayed, the contact surface can be avoided on the structure, and the structural strength can be improved.
- Adding sodium gluconate to the concrete mixture can delay the setting time, which is important for long or difficult perfusion.
Now in the concrete industry, pre-mixed concrete is made at a central location and delivered by a mixer truck. In this case, it is important to delay the initial solidification time of concrete. - Oil well grouting is difficult to operate due to high temperatures. After adding sodium gluconate, the mud can work at 170℃ for several hours.
(2) Used as water reducing admixture. It can reduce the mixing water consumption of concrete and increase the strength of concrete while maintaining the consistency of concrete, cement dosage and slump. The water to cement ratio (W/C) is constant, in this case, the addition of sodium gluconate can improve concrete workability. While the cement content remains the same, it can reduce the water content in the concrete. When the amount of sodium gluconate added is 0.1%, the amount of water added can reduce by 10%. Besides, it can reduce cement content.
In the water treatment industry, sodium gluconate has an excellent effects on corrosion and scale inhibition, so it is widely used as a water quality stabilizer, for example, it can be used as a treatment agent for circulating cooling water systems in petrochemical enterprises, low pressure boilers, and cooling water systems for internal combustion engines.
In the medicine industry, sodium gluconate can regulate the acid-base balance in the human body, so it can help to restore normal nerve function.
Sodium gluconate plays an important role in medical, for example, it can maintain extracellular osmotic pressure and volume, regulate acid-base balance, and exert normal functions of neuromuscular.
It can be used as a nutritional supplement, besides, it can also prevent hyponatremia.
- Replace salt. It not only can reduce sodium absorption in the body, but also has a good soothing effect on nervousness. In fact, related studies have shown that excessive intake of sodium induces the production of hypertension. The salty taste of sodium gluconate is close to that of salt, while its content of sodium is only a quarter of that of salt. Compared with other low sodium salts, Acid sodium salt has some advantages, such as no irritation, no bitter taste or salty taste, it has become the best substitute for salt.
- Improving food flavor. In the food industry, the flavor is the most important indicator for measuring the sensory function of food. In fact, studies have found that gluconic acid sodium salt has the effect of masking the bitterness of food and improving the taste. All in all, it has a significant effect on the improvement of food flavor.
Sodium gluconate could form complexes with metal ions that influence the appearance and stability of cosmetic products. It is especially used in cosmetic and personal maintenance systems due to its chelating characteristics.
Adding sodium gluconates in shampoos and cleansers to improve their lather by sequestering hard water ions. It can be found in toothpaste to sequester calcium and help prevent gingivitis. Sodium Gluconate can be present in soaps and face creams.
In industry, glucose-containing substances (such as grains) are generally used as raw materials, and gluconic acid is prepared from glucose by fermentation, and then neutralized by sodium hydroxide to obtain sodium gluconate. In addition, we can also synthesize sodium gluconate by electrolysis and oxidation.
