Formula IngredientChelating AgentSodium Gluconate
INCI: Sodium Gluconate
Sodium gluconate is the sodium salt of gluconic acid, functioning primarily as a chelating agent and secondarily as a humectant in cosmetic formulations. It works by neutralising metal ions (particularly iron and copper) present in water and raw materials, preventing formula discolouration and rancidity of cosmetic oils over time. It also has mild humectant properties, helping skin retain moisture.

Is Sodium Gluconate safe? Key considerations
Can Sodium Gluconate cause irritation?
Low RiskSodium gluconate is well tolerated at typical cosmetic concentrations. It is Ecocert and Cosmos approved as a natural ingredient. No EU CosIng Annex II or III restrictions apply.
Does Sodium Gluconate increase sun sensitivity?
No RiskSodium gluconate does not increase photosensitivity. No sun protection precautions are required based on its presence in a formulation.
Is Sodium Gluconate safe during pregnancy?
SafeSodium gluconate is the sodium salt of a naturally occurring acid (gluconic acid) and is also used as a food additive (E576). It has no known reproductive or developmental toxicity and is considered safe for use during pregnancy at cosmetic concentrations.
