Sodium gluconate

Sodium gluconate is the sodium salt of gluconic acid, a naturally occurring organic acid derived from glucose. It is produced through the fermentation of glucose by microorganisms or through chemical oxidation. Sodium gluconate is a white, crystalline powder that is highly soluble in water and has a wide range of applications in various industries due to its chelating, sequestering, and stabilizing properties.

Properties

Sodium gluconate has the following key properties:

• Solubility: Highly soluble in water, making it suitable for aqueous solutions.

• Chelating Ability: It forms stable complexes with metal ions, particularly calcium, iron, and aluminum, even at high pH levels.

• Biodegradability: It is environmentally friendly and biodegradable, making it a sustainable choice for many applications.

• Non-Toxicity: It is safe for use in food, pharmaceuticals, and personal care products.

Applications

Sodium gluconate is widely used in various industries due to its versatile properties:
