Edetate disodium (disodium EDTA) is a chelating agent that binds metal ions in cosmetic formulations, improving product stability, preserving efficacy, and enhancing the performance of preservatives. It is widely used at low concentrations as a formulation aid rather than as an active treatment ingredient.

| Mild skin irritation | Uncommon | Transient redness or stinging, typically at higher concentrations or on compromised skin. |
| Allergic contact dermatitis | Rare | Sensitization has been documented in isolated patch-test cases. |
| Eye irritation | Rare | Possible with direct ocular exposure in rinse-off or eye-area products. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
