Definition: Sodium gluconate is the sodium salt of gluconic acid, a naturally occurring sugar. It comes in different forms, including a clear, colorless liquid and a white, crystalline powder that dissolves easily in water.

Use in Cosmetics: Sodium gluconate is used in a wide variety of cosmetic products, such as shampoos, conditioners, lotions, creams, and makeup. It serves multiple roles in these products:

  • Chelating Agent: Sodium gluconate can bind to metal ions, preventing them from reacting with other ingredients. This helps improve the stability and shelf life of the product.
  • Humectant: Sodium gluconate can attract and retain moisture, aiding in skin and hair hydration. This makes it a valuable addition to products meant to moisturize and condition the skin and hair.
  • pH Adjuster: Sodium gluconate can also be used to adjust the pH of a product to a desired level, ensuring the product maintains an optimal level for use and effectiveness.
Other Names: Sodium gluconate may also be referred to as gluconic acid monosodium salt, D-gluconic acid sodium salt, Monosodium salt D-gluconic acid, and sodium D-gluconate.

Skin Sensitivities: Sodium gluconate is generally considered safe for most people. However, as with any skincare ingredient, individual allergies or sensitivities may occur. If you have sensitive skin, performing a patch test before using any product containing sodium gluconate is a good practice.

Other Risks: Sodium gluconate is generally considered safe, but it is corrosive to metals. Therefore, keeping products containing sodium gluconate away from metal surfaces is important. Despite its corrosive properties towards metals, sodium gluconate is not considered to be toxic, carcinogenic, or harmful to the reproductive system in humans. Avoid contact with the eyes or ingestion, and use products as directed.
