Abstract
A tablet of compacted particulate detergent composition comprises a detergent-active compound, a detergency builder, and optionally other detergent ingredients. The tablet, or a discrete region thereof, consists essentially of a matrix of particles substantially all of which have a particle size within a range having upper and lower limits each lying within the range of from 200 to 2000 .mu.m and differing from each other by not more than 700 .mu.m.
Claims14
A tablet of compacted particulate detergent composition comprising from 2% to 50% by weight of the composition of a detergent-active compound selected from the group consisting of anionic, cationic, nonionic amphoterie, zwitterionic surface active agents and mixtures thereof, from 20% to 80% by weight of the composition of a detergency builder comprising alkali metal aluminosilicates, and optionally other detergent ingredients, characterized in that the tablet, or a discrete region thereof, consists essentially of a matrix of particles at least 90 wt % of which have a particle size within a range having upper and lower limits each lying within the range of from 200 to 2000 .mu.m and differing from each other by not more than 700 .mu.m wherein not more than 5 wt % of said particles should be larger than the upper limit and not more than 5 wt % of said particles should be smaller than the lower limit.
