Sodium gluconate is a white, water-soluble powder, also known as the sodium salt of gluconic acid.
It’s a common chelating agent and stabilizer used in various industries, including food, pharmaceuticals, cosmetics, and cleaning products. Its primary function is to bind with metal ions, preventing them from reacting with other substances and thus stabilizing formulations, adjusting pH, and improving the effectiveness of cleaning agents
What is SODIUM GLUCONATE used for?
Sodium gluconate is a useful ingredient when it comes to personal care and cosmetics. From increasing the shelf life of the products to making them more appealing for the user – this ingredient does it all.
- Skin care: In skin care products, it is commonly used as a chelating agent, which means it can help to remove unwanted metals from formulations – which ultimately improves their stability and texture. Sodium gluconate is also a good preservative, as it can help prevent the growth of harmful bacteria and fungi in the products, extending their shelf life
- Hair care: It is used to improve the performance and appeal of many hair care products. It removes unwanted metal ions from the products, improving the clarity and reducing the buildup of minerals on hair. Sodium gluconate also prevents dryness and breakage, leaving hair looking and feeling healthier
- Cosmetic products: Apart from being a chelating agent, sodium gluconate is also good at hydration. It makes the cosmetic products more hydrating for the skin and prevents the surface from drying out by retaining water. Overall, this ingredient improves the user experience and the appeal of the products
Origin
Sodium gluconate is made through the fermentation of glucose using bacteria, such as Aspergillus niger or Gluconobacter suboxydans. The resulting gluconic acid is then neutralized with sodium hydroxide to form sodium gluconate.
