Detergent tablet

A tablet composition suitable for use in detergents, bleaching, sanitization, water treatment, denture cleansing, etc, the tablet composition comprising a cross-linked polymeric disintegrant having an average particle size above about 400 microns, an arithmetic mean particle size of less than about 400 microns, and a particle size distribution such that at least about 40% by weight thereof falls in the range from about 250 to about 850 microns, with less than about 40% greater than about 850 microns.

A detergent tablet for use in a washing machine, the detergent tablet comprising a plurality of compressed phases and having differing concentrations of cross-linked polymeric disintegrant in at least two of the phases, such as to provide differential dissolution of the at least two phases in a washing machine.

A detergent tablet for use in a washing machine, the detergent tablet comprising a plurality of compressed phases having differing concentrations of disintegration retardant in at least two of the phases and at least one of which phases comprises a cross-linked polymeric disintegrant such as to provide differential dissolution of the at least two phases in a washing machine.

A detergent tablet for use in a washing machine, the tablet having one or more phases at least one of which is in the form of a compressed particulate solid comprising a cross-linked polymeric disintegrant and a cogranulated detergency additive composition comprising polymeric polycarboxylate and inorganic carrier.

A detergent tablet for use in a washing machine, the tablet having one or more phases at least one of which is in the form of a compressed particulate solid comprising a cross-linked polymeric disintegrant and a cogranulated detergency additive composition comprising partially hydrated detergency builder and liquid or liquifiable surfactant.

A tablet for use in a washing machine, the tablet comprising an amine oxide surfactant and a cross-linked polymeric disintegrant.

A method of removing tea and other coloured food stains from dishware/cookware in an automatic dishwashing machine comprising contacting the stained dishware/tableware with a washing liquor comprising from about 3 to about 100 ppm of an insoluble particulate cross-linked polymer having an average particle size above about 400 microns, and optionally from about 20 to about 100 ppm of a bleaching agent.
