Trisodium Ethylenediamine Disuccinate
Trisodium Ethylenediamine Disuccinate
A readily biodegradable chelator — a greener alternative to EDTA that binds stray metal ions to keep a formula stable.
What it does
Like EDTA, this ingredient is a chelator: it grabs trace metal ions that would otherwise speed spoilage and degrade actives, and it helps preservatives work. It is chosen as a more environmentally friendly, biodegradable option. Used at low levels, it protects the formula rather than acting on the skin.
