Sodium Gluconate

Sodium Gluconate (C₆H₁₁NaO₇)

Sodium gluconate is the sodium salt of gluconic acid, known for its excellent chelating ability, especially with calcium and other divalent metal ions. It appears as a white crystalline powder and has a molecular formula of C₆H₁₁NaO₇. With a purity of 98% and a pH range of 6 to 8 in 10% solutions, sodium gluconate is widely used in various industrial applications due to its versatility, biodegradability, and non-toxic nature.

Thanks to its high solubility and stability under alkaline conditions, sodium gluconate is an ideal additive in sectors such as construction, water treatment, cleaning, textile, oil drilling, and chemical manufacturing. It functions as a water reducer, set retarder, dispersing agent, stabilizer, and cleaning agent depending on the area of application.
