Disodium EDTA

What is it?

A synthetic metal-chelating agent widely used in cosmetic formulations to bind trace metal ions, improving product stability and preservative efficacy -- not an active skincare ingredient itself.

What does it do?

According to PubMed, a formulation-stability study comparing retinol-stabilizing systems found the long-standard EDTA + BHT combination effectively controlled retinol degradation via metal chelation and antioxidant action, though the study's own newer eco-friendly alternative performed somewhat better on biodegradability -- real evidence for EDTA's established chelating role in cosmetic formulation.
