Abstract

A particulate laundry detergent composition which comprises, as separate particulate components: (a) at least 10 wt % granular detergent base powder comprising surfactant and builder and having a bulk density of at least 0.5 kg/l, preferably at least 0.6 kg/l; and (b) no more than 10 wt % particulate sodium carbonate, wherein the sodium carbonate has a size/density index (SD) of no more than 200, preferably no more than 150, more preferably no more than 100, desirably no more than 75 and especially no more than 50, wherein SD=bulk density (kg/l)×d50 particle size (microns). The sodium carbonate preferably has a d50 particle size of no more than 300 microns, preferably no more than 200 microns.
