DESCRIPTION

Sodium Gluconate is typically supplied as a white to off-white crystalline powder or granular solid with little to no odor.
Sodium Gluconate is the sodium salt of gluconic acid and dissolves readily in water to form clear solutions.
Sodium Gluconate acts as a chelating and sequestrant agent by binding metal ions such as calcium, iron, copper, and aluminum.

Sodium Gluconate improves stability of formulations by reducing metal-catalyzed oxidation that can cause discoloration and odor change.
Sodium Gluconate is effective in alkaline environments, which makes Sodium Gluconate especially useful in many cleaning and construction applications.
Sodium Gluconate can function as a dispersant, helping reduce particle agglomeration and improving uniformity in suspensions.

Sodium Gluconate performance depends on concentration, pH, temperature, and the metal ion profile of the system.
Sodium Gluconate should be stored properly to prevent moisture pickup and clumping during storage.
Sodium Gluconate is commonly selected when a biodegradable chelant is desired to replace stronger, less biodegradable chelators in some applications.
