Abstract
In order to provide a particulate zero-phosphate laundry detergent composition with reduced tendency to agglomeration, the composition comprises: (i) from 30 to 80 wt.% of a granular base powder comprising: a) from 5 to 60 wt.% (based on the composition) of organic surfactant, and b) from 10 to 80 wt.% (based on the composition) of alkali metal aluminosilicate detergency builder, (ii) from 1 to 5 wt.% of sodium silicate not within the granular base powder, wherein the sodium silicate (ii) is all present in the form of separate cogranules consisting essentially of sodium silicate and sodium carbonate in a ratio within the range of from 3:1 to 1:3, and where the tendency of the composition to form granules having a particles size of 2000 µm or larger on storage is less than if the sodium silicate (ii) were present in the form of separate granules of sodium disilicate.
Optionally, the composition may comprise from 1-50 wt.% of separate granules of sodium carbonate, 10 to 35 wt.% of separate granules of peroxy bleach compound and other detergent materials up to 100 wt.%.
Optionally, the composition may comprise from 1-50 wt.% of separate granules of sodium carbonate, 10 to 35 wt.% of separate granules of peroxy bleach compound and other detergent materials up to 100 wt.%.
