Concern level
High concern
Disodium EDTA is a chelating agent that binds trace metal ions in cosmetic formulas. By sequestering metals, it helps improve product stability, reduce discoloration and oxidation, and support preservative performance. It is typically used at very low levels and is not an active skin treatment ingredient, but a formulation-support ingredient.

Interactions
incompatible with: May reduce stability or activity of metal-ion-dependent ingredients, Can complex with trace metals such as iron, copper, and calcium, May alter performance of preservatives or actives when formulation depends on free metal ions
Risks & Warnings
Generally low risk at cosmetic use levels. Rare concerns include mild skin or eye irritation in very sensitive users. Because it is a chelator, it can affect the availability of trace metals in a formula, which is usually desirable for stability but may reduce the effectiveness of some metal-dependent ingredients in the same system.
