Trisodium Ethylenediamine Disuccinate

INCI: Trisodium Ethylenediamine Disuccinate

Trisodium ethylenediamine disuccinate (EDDS) is a biodegradable chelating agent used in cosmetic formulations to neutralise metal ions (particularly copper and iron) that typically originate from water. By binding these metal ions, it extends product stability and shelf life. It is notably selective, targeting problematic metal ions while being less aggressive toward benign ones like calcium and magnesium.
