EDTA disodium is a widely used chelating agent in washing. It can form stable complexes with metal ions, effectively removing scale and stains.
The application of EDTA disodium in laundry includes water softening, enhancing detergent performance, preventing color fading, and improving washing efficiency. It binds with metal ions like calcium and magnesium, reducing scale deposition and making washing machines and clothes easier to clean.
