Abstract
Abstract A particulate laundry detergent composition is provided comprising: (a) from about 0.1 to about 50%, by weight, of a perfume-containing carrier comprising (i) discrete particles containing at least 75%, by weight, of a clay mineral other than talc and/or a zeolite, and less than about 5%, by weight, of surface active detergent compounds; and (ii) a perfume, said perfume being adsorbed and/or absorbed on said particles; and (b) from about 2 to about 50%, by weight, additional to any detergent compound in said particles, of one or more surface active detergent compounds selected from the group consisting of anionic, nonionic, cationic, ampholytic and zwitterionic detergent compounds. The balance of the composition is comprised of water and optionally builder and filler salts.
