Disodium EDTA is a chelating agent that binds metal ions in cosmetic formulations, improving product stability, preserving efficacy, and enhancing the performance of preservatives and surfactants. It is used at low concentrations as a formulation additive rather than as a skin-active ingredient.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation | Rare | Mild irritation possible, generally at higher concentrations or on compromised skin. |
Allergic contact dermatitis | Rare | Sensitization has been reported but is uncommon for the concentrations used in cosmetics. |
Enhanced penetration of other ingredients | Uncommon | By disrupting the skin barrier slightly, it may increase absorption of co-formulated substances. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
