Sodium Gluconate – Natural Chelating Agent and Formulation Stabilizer
Sodium Gluconate is a natural, biodegradable chelating agent that helps stabilize and protect cosmetic and personal care formulations. It binds trace metal ions such as iron and copper, which can cause oxidation, rancidity, and discoloration in products like creams, lotions, shampoos, soaps, and serums.
Derived from the fermentation of glucose, Sodium Gluconate offers a natural alternative to synthetic chelating agents such as EDTA. It improves product stability, supports a cleaner shelf life, and enhances performance in formulations exposed to hard water or mineral-rich environments.
