Claim:
A solid laundry detergent composition having a bulk density of from about 100 g/l to 500 g/l, wherein the composition comprises: (a) from about 1 wt % to about 70 wt % anionic detersive surfactant; (b) from about 0 wt % to about 10 wt % zeolite builder; and (c) from about 0 wt % to about 10 wt % phosphate builder; wherein the composition comprises: (I) from 70 wt % to about 90 wt % low-density particulate component, wherein the low-density particulate component has a bulk density of from about 100 g/l to about 400 g/l and wherein the low-density particulate component comprises inorganic and organic material; and (II) from about 10 wt % to 30 wt % high-density particulate component, wherein the high-density particulate component has a bulk density of from 600 g/l to about 5,000 g/l, and wherein the high-density particulate component comprises: a first discrete population of homogeneous high-density particles comprising an ethoxylated alcohol sulphate anionic detersive surfactant co-granulated with sodium sulphate and sodium carbonate; and a second discrete population of homogeneous high-density particles consisting essentially of sodium percarbonate at least partially coated by a coating material; wherein: the weight ratio of the inorganic material to the organic material in the low-density particulate component (I) defines a low-density particulate ratio; the weight ratio of the inorganic material to the organic material in the solid laundry detergent composition defines a total-composition ratio; the low-density particulate ratio is from 0.3:1 to 5:1; the total-composition ratio is from 0.3:1 to 1.5:1; and the ratio of the low-density particulate ratio to the total-composition ratio is from 0.3:1 to 5:1.
