YUANLIAN CHEMICAL Bio-based chelating agent MGDA.Na3: High coordination efficiency from the perspective of aminocarboxylic acid structure

The green chelating agent N,N-dicarboxymethyl alanine trisodium MGDA・Na3 is a product with excellent performance and wide application. It is not only suitable for a variety of fields, but also has outstanding toxicological safety characteristics, and is biodegradable and stable, and is very environmentally friendly. As a metal ion chelating agent, MGDA・Na3 can form stable water-soluble complexes with metal ions, with a wide range of applicable pH values, and can also produce synergistic effects with fungicides in the system to enhance the use effect.

In practical applications, MGDA・Na3 can be used as an ideal alternative to traditional chelating agents such as organic phosphonates, NTA, EDTA, and citrate.

l  In the detergent industry, it can be used as an effective builder for phosphorus-free detergents and as a stabilizer for sodium perborate/sodium percarbonate.

l In commercial phosphorus-free dishwashing formulas, MGDA・Na3 has been proven to have high efficiency in rinsing and removing stubborn dirt.

l In high-efficiency laundry detergents, laundry liquids, and soap-based detergents, it can also show excellent cleaning power.

l Adding it to various soaps can also prevent rancidity, discoloration, and inhibit dirt precipitation.

l In addition, as a descaling and antiscaling agent, MGDA・Na3 can effectively prevent scale formation, soften water quality, and re-dissolve metal salts and hydroxides.

 It is used to clean a variety of industrial insoluble salt scales and also plays an important role in the field of industrial cleaning.

The core advantage of the green chelating agent N,N-dicarboxymethylalanine trisodium (MGDA・Na3) lies in its excellent chelating ability. It can be used as an ideal substitute for traditional chelating agents. The amount added in actual applications can be flexibly adjusted according to the specific field and usage effect.

On a dry basis, its typical chelation values for various metal ions are as follows:

calcium ion (Ca²⁺) 60mg/g

copper ion (Cu²⁺) 96mg/g

MGDA・Na3, zinc ion (Zn²⁺) 98mg/g

ferrous ion (Fe²⁺) 84mg/g

magnesium ion (Mg²⁺) 36mg/g

manganese ion (Mn²⁺) 83mg/g
