GLDA and MGDA, an ideal replacement for EDTA, DTPA, HEDP and NTA

In the field of industrial production and household cleaning, chelating agents are important chemical additives and are widely used in many industries such as washing, water treatment, textiles, and agriculture. However, although traditional chelating agents such as EDTA (ethylenediaminetetraacetic acid), HEDP, DTPA and NTA (nitrilotriacetic acid) have significant effects, they have problems and disadvantages, like EDTA series and DTPA series chelating agents are hard biodegradable, which will easy to cause soil compaction, and not friendly to the soil ecological environment; and HEDP series contain phosphine, which can easily cause eutrophication of water bodies and is not friendly to the aquatic ecosystem; and NTA belongs to a carcinogen, has the risk of leading cancer, and is not friendly to people. With the improvement of global environmental awareness, the market demand for eco-friendly, wholly-biodegradable, personal- friendly and efficient chelating agents is becoming increasingly urgent.

To meet the markets’ demands, Jining Yuanlian Chemical Technology Co..ltd. developed out eco-friendly chelating agent : Tetrasodium Glutamate Diacetate (GLDA-4NA); Methylglycine N,N-diacetic acid, trisodium salt(MGDA-3Na). They do not only have excellent chelating ability, but also has the advantages of wholly-biodegradable, environmentally friendly and highly safe to people. They already known as two ideal substitutes for traditional chelating agents in Europe, USA etc. developed countries.

Tetrasodium Glutamate Diacetate (GLDA-NA4) is a bio-based chelating agent synthesized from natural amino acid (glutamic acid). GLDA biodegrades over 80% and MGDA biodegrades over 70% within 28 days. And GLDA has 56% carbon / 48% weight is derived from natural plant sources. GLDA and MGDA possess a broader and more efficient chelating capacity for metal ions, can stably chelate Ca²⁺, Mg²⁺, Fe³⁺, and Cu²⁺ etc.

Jining Yuanlian Chemical Technology Co.Ltd., as a professional and advanced eco-friendly chelating agent manufacturer in China. Look forward to the cooperation with you.
