Disodium EDTA is a chelating agent that binds metal ions (such as calcium, iron, and copper) in cosmetic formulations, improving product stability, preventing discoloration, and enhancing the efficacy of preservatives. It is used at low concentrations as a formulation aid rather than a skin-active ingredient.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Rare | Possible at higher concentrations or on compromised skin barrier. |
Allergic contact dermatitis | Very rare | Sensitization to EDTA is uncommon but has been documented in case reports. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
