Trisodium ethylenediamine disuccinate (EDTA-3Na) is a water-soluble compound commonly used in the cosmetic industry as a chelating agent. It works by binding to metal ions, such as calcium and iron, thereby preventing them from causing undesirable reactions that may impact product texture and stability. Trisodium ethylenediamine disuccinate helps to keep cosmetic products looking and performing their best. It has a white or slightly yellow appearance in powder form, and its chemical formula is C10H16N2O8. Its ability to sequester metal ions makes it an essential ingredient in many cosmetic formulations, especially those that contain surfactants or preservatives.
Trisodium ethylenediamine disuccinate is synthesized from ethylenediamine, sodium hydroxide, and succinic acid. The reaction involves the condensation of ethylenediamine and succinic acid, followed by the addition of sodium hydroxide to form the trisodium salt. The resulting compound is then purified to produce the final product.
