Sodium Gluconate

Sodium gluconate is the sodium salt of gluconic acid. Gluconic acid is a product of glucose fermentation. This ingredient is used mainly as an active chelating agent in cosmetic formulation-that is, as a substance that binds with metal ions like iron and copper. Through the process of binding these metal ions, the sodium gluconate prevents their interaction with other ingredients of the product, hence stabilizing the formulation. This process inhibits the formulation of off-flavors, colors, and odors within oils and extends the product's shelf life.
Apart from its chelation properties, it is a pH adjuster that keeps the product at an optimal acidity or alkalinity for stability and skin compatibility. It is a humectant that has properties to hold the skin's moisture by attracting water molecules. This improves hydration of the skin to keep it soft and smooth.
It is also used in oral care: in that case, it masks the bitterness of certain active ingredients, which generally improves the taste of the formulation. Therefore, it is an important toothpaste and mouthwash additive, while improving the sensorial without compromising its effectiveness.
Thanks to such multifunctionality, sodium gluconate is appreciated not only in skincare, where it plays a stabilizing, moisturizing, and pH-regulating role, but also in oral care, where the ingredient enhances taste and product stability. Mild and combined with a wide circle of cosmetic ingredients, this is an ingredient versatile and widely used in personal care products.
