Chelating Agent
Chelating Agent — an ingredient that binds trace metal ions, such as iron and copper, that can enter a formula through water or raw materials. By locking up these metals, it helps preserve product stability, prevent discoloration and rancidity, and support the effectiveness of other preservatives.
Key points
- Chelators bind metal ions that would otherwise catalyze oxidation and degrade a product over time.
- Common examples include EDTA, sodium phytate, and sodium gluconate.
- They boost preservative efficacy, allowing formulators to keep products stable and safe.
- Chelating agents are used at low concentrations and function as formulation support rather than active skincare ingredients.
Frequently asked
What does a chelating agent do in skincare?
It binds stray metal ions in a formula to prevent oxidation, discoloration, and spoilage while helping preservatives work more effectively.
Are chelating agents active ingredients for the skin?
No, they are functional formulation aids that stabilize the product rather than deliver a direct benefit to the skin.
