Disodium EDTA is a chelating agent that binds metal ions in cosmetic formulations, enhancing product stability and improving the efficacy of preservatives and surfactants. It is widely used as a formulation aid rather than as a skin treatment active.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation | Uncommon | Mild irritation may occur, typically at higher concentrations or with prolonged exposure. |
Allergic contact dermatitis | Rare | Sensitization is uncommon but has been reported in patch-test studies. |
Enhanced penetration of other ingredients | Uncommon | By disrupting skin barrier integrity, it may increase absorption of co-formulated substances. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
