Tetrasodium N,N-biscarboxylatomethyl-L-glutamate

  • CAS No.- 51981-21-6
  • INCI.- Tetrasodium glutamate diacetate,

Tetrasodium glutamate diacetate (GLDA) is a chelating agent produced from a naturally occurring amino acid.
Tetrasodium glutamate diacetate is readily biodegradable with a high level of solubility over a wide pH range and is thus a greener alternative to many other chelates.
Tetrasodium glutamate diacetate is an Nitrilotriacetic acid(NTA)-free, powerful chelating agent and preservative-booster made from natural, biodegradable, renewable raw materials.
It can be used as a more sustainable alternative to phosphonates and commonly used chelating agents (NTA and Ethylenediaminetetraacetic acid (EDTA) in a wide number of applications.
Its dispersion properties combined with easier rinsing support the Tetrasodium glutamate diacetate find its place in modern wash-off formulations, as well as in wipes and shaving products.

Tetrasodium glutamate diacetate can be used to replace EDTA in a 1:1 ratio in many applications and products. It also does not sensitize human skin and provides enhanced biocidal/preservative boosting power when compared to commonly used boosters such as EDTA and NTA.
It is suitable to for use in personal care and cosmetics products, and due to the strong chelating ability of calcium and transition metal ions, it can prolong the shelf life of many products, as well as stabilize and prevent them from discoloration.
