Sodium Gluconate

What is Sodium Gluconate?

Sodium gluconate is the sodium salt of gluconic acid, produced by fermenting glucose from natural sources like corn or fruits. In cosmetics, it functions mainly as a chelating agent, capturing trace metal ions such as calcium, iron, or magnesium that could otherwise promote oxidation, rancidity, or discoloration in formulations. This preserves the integrity and shelf life of products like lotions, shampoos, and serums. It also works as a skin conditioning agent by aiding moisture balance on the skin's surface, promoting a smoother texture. Its water-soluble nature allows easy incorporation into water-based products without altering viscosity or feel. Derived through a mild biotechnological process, it offers a biodegradable alternative to synthetic chelators, supporting cleaner formulation practices while remaining compatible with sensitive skin types.
