Formula IngredientChelating AgentTetrasodium Glutamate Diacetate
INCI: Tetrasodium Glutamate Diacetate
Tetrasodium glutamate diacetate is a biodegradable chelating agent derived from the amino acid L-glutamic acid. It works by binding and neutralising metal ions (particularly iron and copper) present in water and raw materials, preventing formula degradation, discolouration, and rancidity. It is marketed as a greener, readily biodegradable alternative to traditional EDTA chelators, with comparable performance in stabilising cosmetic formulations.

Is Tetrasodium Glutamate Diacetate safe? Key considerations
Can Tetrasodium Glutamate Diacetate cause irritation?
Low RiskTetrasodium glutamate diacetate is well tolerated at typical cosmetic concentrations. It is derived from a naturally occurring amino acid and used at very low levels. No EU CosIng Annex II or III restrictions apply.
Does Tetrasodium Glutamate Diacetate increase sun sensitivity?
No RiskTetrasodium glutamate diacetate does not increase photosensitivity. No sun protection precautions are required.
Is Tetrasodium Glutamate Diacetate safe during pregnancy?
SafeTetrasodium glutamate diacetate is derived from L-glutamic acid, a naturally occurring amino acid. It is used at very low concentrations as a chelating agent with minimal systemic absorption. No reproductive or developmental toxicity concerns noted. Considered safe during pregnancy.
