Trisodium Ethylenediamine Disuccinate (Trisodium Ethylenediamine Disuccinate, or HEDTA-type biodegradable chelator) is a biodegradable chelating agent used to bind metal ions in cosmetic formulations. By sequestering trace metals, it helps stabilize products, prevent discoloration and rancidity, and enhance the efficacy of preservatives and antioxidants.
