Summary: | The present disclosure relates to a process to prepare a crystalline co granule of MGDA-Nax, x being 2,5-3, containing a step of drying a crumbly phase composition containing on total weight of the composition(i) 70-87 wt % of organic compounds and salts thereof containing 85 to 100 wt % on total organic compounds and salts thereof of MGDA-Nax, wherein at least 60 wt % of the MGDA-Nax is crystalline, and(ii) 13-30 wt % of waterin the presence of a second composition containing at least one second component selected from the group of scale inhibitors, crystal inhibitors, film or spot preventing polymers, glass-corrosion inhibiting agents, pH modifiers, chelating agents, builders, bleaching agents, and surfactants. It also relates to the co granules obtainable by the process. |
