  • BUILDER GRANULES AND PROCESS FOR THEIR PREPARATION
    Publication number: 20160376529
    Abstract: A process for preparing builder granules suitable for use in a granular or tabletted detergent compositions, particularly for machine dishwash, involves forming a slurry of solid and aqueous MGDA Na3 spray dryer, under non-agglomerating conditions, to form spray dried particles comprising solid crystalline MGDA Na 3 dihydrate, compacting the spray dried particles into compacted aggregates and comminuting the compacted aggregates into granular particles to form builder granules having a particle size distribution suitable for use in a granular detergent composition. Prior to spray drying, the slurry is maintained at a slurry temperature of 20° or more for sufficient time for the resulting builder granules to remain free flowing after 48 hours storage at 20° C. and 65% relative humidity.
    Type: Application
