Abstract

The present invention relates to a solid laundry detergent composition having a bulk density of from 100 g/l to 500 g/l, wherein the composition comprises: (a) from 1 wt % to 70 wt % anionic detersive surfactant; (b) from 0 wt % to 10 wt % zeolite builder; and (c) from 0 wt % to 10 wt % phosphate builder; wherein the composition comprises: (I) from 61 wt % to 90 wt % low-density particulate component, wherein the low-density particulate component has a bulk density of from 100 g/l to 426 g/l, and wherein the low-density particulate component comprises inorganic material and organic material; and (II) from 10 wt % to 39 wt % high-density particulate component, wherein the high-density particulate component has a bulk density of greater than 426 g/l; wherein the ratio of (i) the weight ratio of the inorganic material to the organic material comprised in the low-density particulate component (I) to (ii) the weight ratio of the inorganic material to the organic material comprised in the solid laundry detergent composition is from 0.3:1 to 5:1.
