MGDA-3Na:

Trisodium methylglycine diacetate, also known as trisodium dicarboxymethylalanine, is a small molecule chelating agent, MGDA-Na3 is a new type of green degradable chelating agent, to replace the traditional Phosphonates, EDTA, NTA. It is suitable for cleaning agents, detergents, pulping and papermaking auxiliaries, textile auxiliaries, daily chemicals, personal care products, oilfield chemical auxiliaries, etc. The use of MGDA-Na3 in the field of cleaning detergent It is biodegradable and can improve the cleaning effect of household and industrial detergents and cleaners.

1. Fabric detergent in heavy-duty laundry detergents, laundry liquids and soap-based detergents, MGDA also exhibits excellent cleaning power, especially for natural oils, sebum, blood stains, milk stains, ink stains, dust and protein and other stubborn stains.  For detergents containing fatty acids and soap in the formulation, it is easy to form soap scales with calcium and magnesium ions in the water during use, and deposits on the surface of the fabric, resulting in acid odor and reduced wettability. MGDA can effectively solve the fouling caused by calcium soap and prevent the redeposition of calcium soap.

2. Automatic dishwashing detergent A large number of phosphorus-containing additives have been used in the formulation of automatic dishwashing detergents. Since the implementation of the prohibition and restriction of phosphorus in various countries, various phosphorus-replacement additives have appeared one after another. The use of non-phosphorus formulations of automatic dishwashing detergents will cause the filming and stain removal performance of the detergent to decrease. But using MGDA can narrow the performance gap between the two. For stubborn stains, such as starch and protein in food, MGDA has been proven to have efficient rinsing and starch stain removal performance in commercial phosphorus-free dishwashing detergent formulations, especially for tea stains.

3. Cleaning of inorganic deposits MGDA can convert poorly soluble compounds into water-soluble substances, and has good solubility for inorganic precipitates. Suitable for old and dry calcium stains.

How to clean calcium carbonate scale in numerous cleanings. In order to dissolve these calcium scales, the equilibrium reaction of forming calcium carbonate must be moved to the direction of generating soluble ions, which can remove carbonate ions or 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 completed by using chelating agents such as MGDA to form soluble complexes, or it can be prevented. New calcium carbonate stains are formed.
