It is commonly used in body washes, cleansers, and shampoos. As a raw material, trisodium ethylenediamine disuccinate comes in either solid or granular form and is white in color. While chelating agents like trisodium ethylenediamine disuccinate aren’t considered “superstar” ingredients, they play a pivotal role in the product’s overall stability, aesthetics, and efficacy. Such ingredients also help bolster a product’s preservative system by keeping metal ions from destabilizing these essential ingredients in water-based formulas. According to the Cosmetic Ingredient Review (CIR) 2022 report, trisodium ethylenediamine disuccinate is used in 228 formulations (68 leave-on formulations and 160 rinse-off formulations) with a maximum concentration of 0.64% at the time of this writing.
