GLDA Na4，Tetrasodium GLDA，Dissolvine GL-47-S，CAS 51981-21-6，C₉H₉NNa₄O₈

Product Name: GLDA Na4
Other Names：Tetrasodium N,N-bis(carboxymethyl)-L-glutamate / Tetrasodium glutamate diacetate / Tetrasodium GLDA / Dissolvine GL-47-S
CAS: 51981-21-6
MF：C₉H₉NNa₄O₈

Product Introduction:
Tetrasodium Glutamate Diacetate (GLDA) features four carboxyl groups, enabling it to bind with nitrogen atoms in molecular structures as well as divalent and trivalent metal ions through strong multiple bonds.

Tetrasodium Glutamate Diacetate is derived from food-grade natural amino acid salt—monosodium L-glutamate (MSG). The use of this bio-based raw material ensures that over half of the carbon content in GLDA is bio-based.

The natural amino acid structure in GLDA’s molecular composition makes it easily recognizable as a food source by bacteria, thereby enhancing its biodegradability.

GLDA is a highly effective chelating agent for hard water metal ions (e.g., Ca²⁺), improving the softening performance, cleaning efficiency, and stability of detergent formulations.

Additionally, GLDA exhibits strong compatibility and stability with most enzyme preparations.
