CAS No.: 164462-16-2 Molecular formula: C7H8NO6Na3 Molecular weight: 271.1 INCI name: Trisodium Dicarboxymethyl Alaninate Chemical name: Methylglycine N,N-diacetic acid, trisodium salt; Trisodium 2-[bis(carboxylatomethyl)amino]propanoate MGDA-Na3 is the abbreviation of trisodium methylglycine diacetate, also known as trisodium dicarboxymethylalanine. It is a small molecule chelating agent with a structure similar to NTA, but it is non-toxic and easily biodegradable. MGDA-Na3 is a new type of non-phosphorus green degradable chelating agent, used to replace traditional phosphonates, EDTA, NTA. Application: cleaning agents, detergents, electroplating electronics industry, oil field chemical additives, pulping and papermaking additives, textile additives, daily chemicals, toiletries, etc.
Physical and chemical properties Items MGDA-Na3, liquid Appearance Light yellow clear liquid Content /% ≥39 pH value ≥8.5 Density(20℃) g/cm3 ≥1.20 Usage of MGDA-Na3 in fields of cleaning and washing: It is biodegradable and can improve the cleaning effect of household, industrial detergents and cleaning agents. 1. Fabric detergent In heavy-duty laundry detergents, liquid laundry detergents and soap-based detergents, MGDA is particularly effective for stubborn stains such as natural oils, sebum, blood stains, milk stains, ink stains, dust and protein. MGDA can effectively solve the stains formed by calcium soap and prevent the redeposition of calcium soap. 2. Phosphorus-free dishwasher detergent 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, has better effect for old and dry calcium stains. 4.Cleaning calcium carbonate scale Use acid (such as hydrochloric acid, citric acid, etc.) to generate carbon dioxide to remove calcium ions, which is not suitable for closed systems and corrosive systems. The use of chelating agents such as MGDA to form soluble complexes to complete this performance without related problems and can prevent formation of new calcium carbonate stains. 5.Cleaning calcium phosphate scale For example, during milk processing, insoluble calcium phosphate precipitates are formed, which is not easy to clean. The complexing ability of MGDA on it exceeds other degradable complexing agents. 更多
