Abstract:
1. A solid laundry detergent composition comprising: (a) a detersive surfactant; (b) from 0 wt % to 10 wt % zeolite builder; (c) from 0 wt % to 10 wt % phosphate builder; (d) carbonate; and (e) a cellulosic polymer; wherein the composition is in free-flowing particulate form and comprises at least two separate particulate components, wherein the first particulate component comprises: (i) an anionic detersive surfactant; (ii) at least 10 wt %, by weight of the first particulate component, of carbonate; (iii) from 0 wt % to 10 wt %, by weight of the first particulate component, of zeolite builder; (iv) from 0 wt % to 10 wt %, by weight of the first particulate component, of phosphate builder; and (v) from 0 wt % to less than 5 wt%, by weight of the first particulate component, of cellulosic polymer; and wherein the second particulate component comprises: (i) at least 0.20 wt %, by weight of the second particulate component, of cellulosic polymer; and (ii) from 0 wt % to less than 20 wt %, by weight of the second particulate component, of carbonate; and a cationic detersive surfactant particle consisting of: 20 wt % mono-C 38.5 wt % sodium carbonate, 38.5 wt % sodium sulphate, 3.0 wt % moisture and miscellaneous; and wherein the first particulate component has a particle size distribution such that it has a weight average particle size of from 250 micrometers to 850 micrometers, and wherein no more than 10 wt % of the first particulate component has a particle size of less than 210 micrometers, and wherein no more than 10 wt % of the first particulate component has a particle size greater than 1,180 micrometers, and wherein the second particulate component has a particle size distribution such that it has a weight average particle size of from 250 micrometers to 850 micrometers, and wherein no more than 10 wt % of the second particulate component has a particle size of less than 210 micrometers, and wherein no more than 10 wt % of the second particulate component has a particle size greater than 1,180 micrometers.
