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.
Claims1
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;
- (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;
- and
- (f) from 3 wt % to 10 wt % water;
- wherein:
- the composition has a bulk density of 600 g/l or less;
- the detergent composition has a cake strength of from 5N to 20N;
- and the composition is essentially free from zeolite builder and does not comprise nonionic detersive surfactants.
