Tetrasodium glutamate diacetate (GLDA)

Original: EDTA free acid

Proposed offset: Tetrasodium glutamate diacetate (GLDA)

Use: Metal-ion and hard-water management in cleaning formulations

Claim to investigate: Nouryon identifies GLDA as a readily biodegradable alternative to EDTA in suitable cleaning applications.

Limits: The existing EDTA target is free acid; GLDA here is the tetrasodium salt. Adjust pH, counterion, actives and molar chelation demand. Metal selectivity, contact time, temperature and formulation pH determine performance.

Core data coverage: 18.75%

3 of 16 defined fields are recorded with a source. This measures structured information currently on this site, not the completeness of every linked PDF. Missing fields remain in the denominator.

Coverage is separate from scientific accuracy, human verification and EcoSafe assessment. Molecular fields may not apply to a grade or family; they are not filled from another material to increase its score.
