Cleaning compositions

A process for making a tablet of compacted particulate cleaning composition or a region thereof comprising at least one cleaning ingredient selected from the group consisting of organic surfactant, detergency builder and bleach, and further comprising water-swellable disintegration-promoting particles, the water-swellable disintegration-promoting particles comprising a) disintegration material selected from the group consisting of (i) cellulosic material from a plant source other than timber and (ii) plant material which contains both cellulose and lignin, obtainable by fragmentation of plant material without separation of its fibers into a liquid dispersion and b) carrier material having a solubility in deionised water at 20° C. of about 1 gram per liter or less, the process comprising the steps of;

• 1) mixing the water-swellable disintegration-promoting particles with other particulate ingredients of a particulate cleaning composition to form a particulate cleaning composition, and
• 2) compacting a quantity of the particulate cleaning composition in a mould to form the tablet of compacted particulate cleaning composition or the region thereof.

A water-swellable tablet disintegration-promoting particle comprising;

• a) disintegration material selected from the group consisting of (i) cellulosic material from a plant source other than timber and (ii) plant material which contains both cellulose and lignin, obtainable by fragmentation of plant material without separation of its fibers into a liquid dispersion, and
• b) carrier material having a solubility in deionised water at 20° C. of about 1 gram per liter or less.

• 1) contacting the disintegration material a) with the carrier material b) to produce a mixture, and
• 2) compacting the mixture to produce the water-swellable tablet disintegration-promoting particles.
