Trisodium Ethylenediamine Disuccinate
What is Trisodium Ethylenediamine Disuccinate?
Trisodium Ethylenediamine Disuccinate is a chelating agent, meaning it binds to metal ions to neutralize them, preserving the efficacy of cosmetic products. It is synthesized from ethylenediamine, a type of amine, and succinic acid, a naturally occurring substance.
This ingredient is used predominantly in skin care products to enhance product stability and shelf life by preventing metal-catalyzed deterioration. There is limited direct research on its safety in humans, but it is generally considered low-risk due to its stability and non-reactive nature when applied topically.
When seen on a label, it's primarily an indication of efforts to increase the product's longevity and to maintain its effectiveness by preventing unwanted metal ion reactions.
Commonly found in: facial cleansers, moisturizers, serums, sunscreens
