MGDA-Na3 CAS 164462-16-2 (Methylglycine diacetate trisodium, or Trisodium Dicarboxymethyl Alaninate CAS 170492-24-7) is an efficient, green, and biodegradable coordination agent. It is an important functional organic acid salt compound, widely used in detergents, cleaning agents, water treatment agents and other fields.
MGDA-Na3 is composed of methylglycine (MGDA) and three molecular equivalents of alkali metals, with good chelating ability and biodegradability. It can effectively coordinate with metal ions, making it less prone to precipitation in water, thereby improving the performance of products such as cleaning agents and water treatment agents.

Technical indicators
Appearance: Light yellow clear liquid 40% 65%; 85% solid form
Solid content ≥ 65% 40% 85% ETC.Application
Phosphorus free and biodegradable, improving the cleanliness of household and industrial detergents and cleaners.
1. Fabric detergent
MGDA is particularly effective in heavy-duty laundry detergent, laundry detergent, and soap based detergents, especially for stubborn stains such as natural oils, sebum, blood stains, milk stains, ink stains, dust, and protein.For detergents containing fatty acids and soap in the formula, they are prone to forming soap deposits with calcium and magnesium ions in water during use, which can deposit on the surface of the fabric, resulting in a sour odor and reduced wettability. MGDA can effectively solve soap scale and prevent the re deposition of calcium soap.
2. Phosphate free dishwasher detergent
Phosphorus containing additives have been extensively used in the formulation of automatic tableware detergents. Since the implementation of phosphorus restriction measures in various countries, various phosphorus substitute additives have emerged. The use of phosphorus free formula in automatic tableware detergent can cause a decrease in the film-forming and stain removal performance of the detergent. Using MGDA can narrow the performance gap between the two.In commercial phosphorus free tableware detergent formulations, MGDA has been proven to have efficient rinsing and starch dirt removal performance, especially effective against tea stains.
3. Cleaning of inorganic precipitates
Methylglycine diacetate trisodium (MGDA) can convert insoluble compounds into water-soluble substances and has good solubility for inorganic precipitates. Suitable for old and dry calcium stains.Cleaning calcium carbonate scale: First, remove carbonate ions, and second, remove calcium ions. The former can be removed by adding acid (such as hydrochloric acid, citric acid, etc.) to generate carbon dioxide, but it is not suitable for closed systems or corrosive systems. The latter can be achieved by using chelating agents such as MGDA to form soluble complexes, and can also prevent the formation of new calcium carbonate stains.
Cleaning calcium phosphate scale: Milk contains a large amount of calcium phosphate, which forms insoluble precipitates during processing and is difficult to clean. EDTA is usually added to solve the problem, but its biodegradability is questioned. MGDA can serve as an upgraded substitute for EDTA, although its chelating performance is not as good as EDTA, it exceeds other degradable chelating agents.
Product advantages
Good biodegradability and no negative impact on the environment.It has strong chelating ability with metal ions such as calcium ions and magnesium ions in hard water, improving the cleaning ability and water quality stability of products such as cleaning agents and water treatment agents.
Compared with other organic acid salt coordination agents, MGDA Na3 has a smaller impact on the environment and is more environmentally friendly.
