  • Difference between 2Na edta and 4Na edta

    Posted by Gulfam on July 26, 2025 at 12:00 am

    What is the main difference between Disodium EDTA (2Na EDTA) and Tetrasodium EDTA (4Na EDTA)? How do we decide which one to use? How does their effectiveness and solubility vary at different pH levels? Does the choice between 2Na EDTA and 4Na EDTA affect the transparency of liquid products, such as dishwashing liquids?

    In a video by the Institute of Personal Care Science, it was mentioned that 4Na EDTA should be used to maintain clarity in formulations. Could you please explain why this is the case?
