TH-GC Green Chelating Agent
(Glutamic Acid,N,N-diacetic Acid, Tetra Sodium Salt)

CAS No: 51981-21-6

Molecular formula: C9H9NO8Na4          Molecular weight: 351.1


TH-GC Green Chelating Agent is mainly prepared from plant-based raw material, L-glutamate. TH-GC Green Chelating Agent is environmental friendly, safe and reliable in utilization, easily biodegradable.

TH-GC Green Chelating Agent is a metal ion chelation agent, and can form stable water soluble complexes with metal ion. It has good solubility in wide pH range with powerful decontamination ability and can achieve synergistic effect with biocides in systems. TH-GC Green Chelating Agent can be widely used as substitute for chelation agent (e.g. NTA, EDTA, etc.) in high polymer chemistry industry, household chemical industry, pulp & paper industry, pharmaceuticals industry, aquaculture, textile dyeing and printing industry, oil field, water treatment industry, boiler cleaning, etc..
