Sodium Gluconate – Natural Chelating Agent and Formulation Stabilizer
Sodium Gluconate is a natural, biodegradable chelating agent that helps stabilize and protect cosmetic and personal care formulations. It binds trace metal ions such as iron and copper, which can cause oxidation, rancidity, and discoloration in products like creams, lotions, shampoos, soaps, and serums.
Derived from the fermentation of glucose, Sodium Gluconate offers a natural alternative to synthetic chelating agents such as EDTA. It improves product stability, supports a cleaner shelf life, and enhances performance in formulations exposed to hard water or mineral-rich environments.
Key Features & Benefits
Natural Chelating Agent: Binds metal ions to prevent oxidation, discoloration, and rancidity in formulations.
Stabilizes Cosmetic Products: Helps maintain color, clarity, and overall product integrity.
Improves Soap Performance: Reduces soap scum, enhances lather, and increases cleaning efficiency in hard water.
Gentle and Safe: Non-irritating, odorless, and not classified as hazardous under GHS standards.
Eco-Friendly: Readily biodegradable and derived from renewable, naturally sourced glucose.
Versatile Use: Suitable for creams, lotions, shampoos, conditioners, sunscreens, and handmade soaps.
