Sodium Gluconate

Functional, Actives & Additives

Sodium Salt of Gluconic Acid

Sodium gluconate is a naturally derived chelating agent produced through the fermentation of glucose, typically from corn or wheat. Like sodium citrate, it functions as a sequestering agent that binds to calcium, magnesium, iron, and other mineral ions that can interfere with formula performance, reduce preservative effectiveness, and cause discoloration or instability in personal care products.

Sodium gluconate is particularly valued for its effectiveness at a wider pH range than some other chelators, and for its compatibility with a broad spectrum of other cosmetic ingredients. It works quietly in the background of our formulas, its contribution invisible but meaningful to formula stability and product longevity.

How It Works

Metal ions present in water and raw materials can catalyze oxidation reactions that cause oils to go rancid, colors to fade, and preservative systems to lose effectiveness over time. Sodium gluconate binds to these ions, sequestering them so they cannot participate in these destructive reactions. The result is a formula that stays fresher, more stable, and more effective for longer, without any change to the sensory experience of the finished product.
