Gluconic Acid Sodium Salt Sodium D-Gluconate Monosodium Gluconate Gluconate de Sodium
Compatibility
Works well with:
Glycerin Sodium Benzoate Citric Acid Niacinamide Panthenol EDTA
Sodium Gluconate is broadly compatible with most cosmetic ingredients and functions synergistically with other chelators such as EDTA or phytic acid to enhance preservation and metal ion control. It is stable across a wide pH range, making it suitable for both acidic and alkaline formulations. No significant incompatibilities are widely reported at typical use levels.
Formulation notes
Sodium Gluconate is the sodium salt of gluconic acid, widely used as a chelating agent to sequester calcium, magnesium, and other trace metal ions that can destabilize emulsions or reduce preservative efficacy. It also provides mild humectancy and is considered biodegradable and environmentally friendly compared to EDTA. It is well-tolerated by skin with a favorable safety profile and is commonly used in rinse-off and leave-on formulations alike.
