A tablet, or a region such as a layer of a tablet, is compacted from a particulate cleaning composition comprising particles which are a mixture of: (i) a water-insoluble, water-swellable material which expands to at least twice its original volume on contact with water; and (ii) other material acting as a carrier therefor, wherein the carrier material is either water-dispersible and present in an amount in the particles which exceeds the amount of material (i), or, it is a starch or a derivative thereof obtainable by chemical treatment of starch which increases its water-solubility. Process for making a tablet comprising said particles. |
