Abstract
A particulate zeolite-built laundry detergent composition having a bulk density of at least 550 g/l comprising at least two different granular components containing both surfactant and builder, preferably one prepared by non-tower granulation and another spray-dried, also contains from 1 to 10 wt % citric acid admixed as a separate particulate component. The admixed citric acid improves dispensing and dissolution properties, whether or not separately admixed sodium carbonate is present.
