AVASEQ Green Chelate – (Glutamic Acid,N,N-diacetic Acid, Tetra Sodium Salt)


AVASEQ Green Chelate is environmental friendly, safe and reliable in utilization, easily biodegradable.

AVASEQ Green Chelate 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.

AVASEQ Green Chelate is mainly prepared from plant-based raw material, L-glutamate. AVASEQ Green Chelate 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.
