complexation of calcium and magnesium ions with trisodium citrate enables EDTA replacement, notably at pH values 10 and 11. Because trisodium citrate and in particular sodium gluconate are very good at sequestering trace metals such as copper they have the capacity to boost stain removal and prolong the shelf life of the formulation.
