Science
Mechanism of Action
In product formulations, Tetrasodium Dicarboxymethyl Aspartate operates by sequestering and deactivating free-roaming metallic ions, such as iron and copper. This chelation process prevents these charged particles from initiating rapid oxidative reactions, which can compromise the stability, color, and efficacy of delicate active ingredients over time, ultimately improving product longevity.

Safety Profile
No dedicated Cosmetic Ingredient Review (CIR) report, Scientific Committee on Consumer Safety (SCCS) opinion, or specific FDA cosmetic status has been found directly for Tetrasodium Dicarboxymethyl Aspartate. However, information on the structurally similar Tetrasodium Glutamate Diacetate (GLDA) suggests it is safe for use in cosmetic applications.
