Disodium EDTA is a chelating agent used in cosmetics to bind metal ions, improving product stability, preventing rancidity, and enhancing the efficacy of preservatives. It is a formulation/base ingredient rather than a treatment active.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Rare | Possible at higher concentrations, usually transient. |
Allergic contact dermatitis | Rare | Sensitization reported in isolated patch-test cases. |
Enhanced penetration of other ingredients | Uncommon | By disrupting skin barrier it may slightly increase absorption of co-applied substances. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
