Technical Specifications

Features of MGDA-Na3

1. Excellent biodegradability
   MGDA-Na3 is a small molecule chelating agent with structure similar to NTA, but it is non-toxic and easily biodegradable, making it an environmentally friendly alternative.

2. Superior cleaning performance
   MGDA is particularly effective for stubborn stains including natural oils, sebum, blood stains, milk stains, ink stains, dust and protein in fabric detergents.

3. Effective scale removal
   MGDA can convert poorly soluble compounds into water-soluble substances, showing exceptional performance on inorganic deposits and old calcium stains.

4. Phosphate-free solution for dishwashing
   In commercial phosphorus-free dishwashing detergents, MGDA has proven effective against tough food stains like starch, protein, and tea stains.

5. Safe for various systems
   Unlike acidic cleaners, MGDA forms soluble complexes to remove calcium carbonate and phosphate scales without corrosion risks, making it suitable for closed systems.
