The invention also provides a tablet of compacted particulate cleaning composition containing at least one cleaning ingredient which is an organic surfactant, a water softening agent or a bleach, wherein the tablet or a discrete region of the tablet contains disintegration-promoting particles of coconut husk material. A process to produce the tablets is also provide which comprises mixing the water-insoluble, water-swellable disintegration-promoting materials with other particulate ingredients so as to form a particulate cleaning composition and compacting a quantity of the particulate composition in a mould so that it forms a tablet or a region of a tablet.
