Abstract

The present invention relates to a solid laundry detergent composition comprising: (a) from 1 wt % to 40 wt % light density silicate salt having a bulk density of less than 400 g/l and a weight average particle size of less than 300 micrometers; (b) from 5 wt % to 60 wt % detersive surfactant; (c) from 0 wt % to 50 wt % carbonate salt; (d) from 0 wt % to 40 wt % sulphate salt; (e) from 0 wt % to 10 wt % phosphate builder; (f) from 0 wt % to 5 wt % zeolite builder; and (g) from 0 wt % to 15 wt % water; wherein the composition has a bulk density of 600 g/l or less.

Claims (8)

1. A solid laundry detergent composition comprising:

(a) from 1 wt % to 40 wt % light density silicate salt having a bulk density of less than 100 g/l and a weight average particle size of less than 300 micrometers;
