About this ingredient

Trisodium EDTA is the trisodium salt form of ethylenediaminetetraacetic acid, a chelating agent used in cosmetics to bind and neutralize metal ions (such as iron, copper, and calcium) that could otherwise catalyze oxidation or discoloration. It stabilizes formulations by preventing metal-catalyzed degradation of active ingredients and preservatives, thereby extending shelf life and maintaining product efficacy.
