Tetrasodium glutamate diacetate CAS 51981-21-6

Tetrasodium glutamate diacetate CAS 51981-21-6

Tetrasodium Glutamate Diacetate (GLDA-Na4) is a new type of green chelating agent with biodegradability. It is widely used in daily chemicals, industrial cleaning and heavy metal remediation. ‌

Chemical properties
The chemical formula is C₉H₁₃NNa₄O₈, the molecular weight is 351.13, and the CAS number is 51981-21-6. Its aqueous solution is light yellow to colorless, and the pH value is usually in the range of 11±1. It has the characteristics of high temperature resistance and wide pH application range, and can stably chelate metal ions under acidic and alkaline conditions. ‌

Environmental protection characteristics
As a new generation of chelating agent, its raw materials are derived from natural glutamic acid (MSG), which is phosphorus-free and easily biodegradable, in line with the trend of green chemistry. Compared with traditional chelating agents such as EDTA and NTA, it has less impact on the environment. ‌

Main applications
‌Daily chemical field‌: used in detergent and cleaning agent formulations to replace phosphorus-containing or non-degradable chelating agents, improve cleaning effects and reduce skin irritation. ‌

‌Industrial field‌: used in metal surface treatment, oilfield chemicals, pulp and paper additives, etc., to chelate metal ions such as calcium and magnesium to improve process efficiency. ‌

‌Heavy metal remediation‌: In soil remediation, it can enhance the absorption of heavy metals such as cadmium by plants and improve remediation efficiency. ‌

‌Synergistic effect‌: used in combination with fungicides to enhance the fungicidal effect and prevent the formula from deterioratingTetrasodium Glutamate Diacetate (GLDA-Na4) is a new type of green chelating agent with biodegradability. It is widely used in daily chemicals, industrial cleaning and heavy metal remediation. ‌
