Abstract:
1. A laundry detergent powder comprising: (i) from about 20 to about 80 wt % of a first particle comprising less than about 55 wt % sulphate, at least about 30 wt % anionic detersive surfactant, between 15 wt % and about 20 wt % silicate, between about 10 wt % and about 40 wt % carbonate, between about 1.5 wt % and 3 wt % of a first polymer, and wherein the first particle is an agglomerate particle having a bulk density of from about 700 g/l to about 1100 g/l: and (ii) from about 20 to about 80 wt % of a second particle comprising at least about 55 wt % sulphate, between about 1 wt % and about 12 wt % anionic detersive surfactant, between about 1 wt % and about 5 wt % silicate, between about 1 wt % and 8 wt % of a second polymer, and having a bulk density of from about 350 g/l to about 600 g/l; wherein the first particle and the second particle are both essentially free of zeolite builder and essentially free of phosphate builder, wherein the first and second polymer are selected from the group consisting of a polyacrylate homopolymer and an acrylic acid/maleic acid copolymer.
