1. Definition Sodium Gluconate:

Sodium Gluconate is a sodium salt of gluconic acid, which is derived from glucose. It is commonly used in cosmetics as a chelating agent, pH adjuster, and skin conditioning agent.

2. Use:

Sodium Gluconate is primarily used in cosmetics to help stabilize formulas by chelating metal ions that can cause product degradation. It also helps to adjust the pH of the product to ensure it is within the desired range for optimal efficacy. Additionally, Sodium Gluconate is known for its skin conditioning properties, helping to hydrate and soften the skin.

3. Usage Sodium Gluconate:

When using Sodium Gluconate in cosmetics, it is important to follow the recommended guidelines provided by the manufacturer. It is typically used in small concentrations, ranging from 0.1% to 2%, depending on the specific formulation. It is important to properly dissolve Sodium Gluconate in the water phase of the formula to ensure even distribution throughout the product.

Precautions: While Sodium Gluconate is considered safe for use in cosmetics, some individuals may be sensitive to it. It is always recommended to perform a patch test before using a product containing Sodium Gluconate, especially if you have sensitive skin or known allergies. If any irritation occurs, discontinue use immediately.
