Sodium Gluconate

Sodium Gluconate is the sodium salt of gluconic acid, produced through the fermentation of glucose by Aspergillus niger or similar microorganisms. It excels as a chelating agent that binds metal ions (particularly iron, calcium, and copper) more gently than EDTA, preventing discoloration and oxidation in formulations while maintaining stability across a wide pH range. Formulators favor it as a 'green' alternative to synthetic chelators because it's derived from renewable resources, readily biodegradable, and provides additional humectant properties that help maintain skin hydration.
