ABSTRACT:
Granular spray-dried detergent compositions containing a crystal-growth-modified carbonate-based structurant salt are produced by a process in which separate slurries of the structurant salt and of the main detergent composition are prepared in different vessels, then mixed and spray-dried. The structural salt is preferably the sodium carbonate/sodium sulphate double salt Burkeite, crystal-growth-modified by means of a polymeric polycarboxylate.
