1. Tetrasodium glutamate diacetate is primarily used as a biodegradable chelating agent, preservative booster, and stabilizer in personal care products, cosmetics, cleaning agents, detergents, and industrial applications .
2. Tetrasodium glutamate diacetate effectively binds metal ions to prevent oxidation, reduces water hardness, prevents precipitation, and extends product shelf life by boosting preservative performance .
3. Tetrasodium glutamate diacetate is also used in soil heavy metal remediation by reducing cadmium content, and as a dietary ingredient to promote volatile fatty acid production from waste activated sludge .
Packed in 1kg/bottle, 25kg/drum.
1. Tetrasodium glutamate diacetate is a synthetic chelating agent derived from the natural amino acid L-glutamic acid, which is produced by biochemical conversion of renewable vegetable materials such as sugar beet waste .
2. Tetrasodium glutamate diacetate is manufactured by reacting monosodium L-glutamate with carboxymethylating agents, resulting in an aminopolycarboxylate compound with the molecular formula C9H9NNa4O8 .
3. Tetrasodium glutamate diacetate is commercially available as a clear, colorless to light yellow liquid or solid powder (≥95-98% purity) from chemical suppliers worldwide .
1. If inhaled, move the person exposed to Tetrasodium glutamate diacetate to fresh air and consult a physician if breathing difficulty or irritation develops .
2. If in eyes, rinse Tetrasodium glutamate diacetate cautiously with water for several minutes, remove contact lenses if present and easy to do, then continue rinsing and get medical attention immediately (P305+P351+P338) .
3. If on skin, wash Tetrasodium glutamate diacetate with plenty of soap and water, remove contaminated clothing, and consult a physician if irritation persists.
1. Store Tetrasodium glutamate diacetate powder in a tightly closed container at -20°C for up to 3 years or at 4°C for up to 2 years for long-term stability .
2. Store Tetrasodium glutamate diacetate stock solutions at -80°C for up to 6 months or at -20°C for up to 1 month, avoiding repeated freeze-thaw cycles .
3. For liquid formulations (approximately 47% concentration), store Tetrasodium glutamate diacetate sealed in a dry, ventilated warehouse away from acidic items, and protect from sun exposure and rain .
