A machine cleaner tablet comprising from about 10 to about 75% of a limescale remover acid, from about 1 to about 20% of low foaming non-ionic surfactant, from about 0.5 to about 5% of a detergency enzyme and wherein the tablet has a pH measured as a 1% solution in distilled water at 20&#xb0; C. in the range from about 1 to about 5. The tablet is used for cleaning the interior of automatic dishwashers, food processing machines and the like.

Detergent tablet

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) a polymeric disintegrant having a particle size distribution such that at least 90% by weight thereof has a particle size below about 0.3 mm and at least 30% by weight thereof has a particle size below about 0.2 mm; and b) a water-soluble hydrated salt having a melting point in the range from about 30&#xb0; C. to about 95&#xb0; C. The detergent tablets display improved dissolution, strength and long-term storage characteristics.

A multi-phase detergent tablet for use in a washing machine, the tablet comprising a first phase in adhesive contact with one or more second phases, at least one second phase being in the form of a compressed particulate solid incorporating liquid adhesive and having an average porosity of less than about 0.15 ml/g. The liquid adhesive is preferably selected from polyethylene glycols having an average molecular weight in the range from about 200 to about 700 and is preferably applied by post-addition to the particulate solid prior to compression. The multi-phase tablets provide improved interphase adhesivity, robustness and strength together with excellent dissolution and cleaning characteristics.

A multi-phase detergent tablet for use in a washing machine, the tablet comprising: a) a first phase in the form of a shaped body having at least one mould therein; and b) a second phase in the form of a particulate solid compressed within the mould. The multi-phase tablets provide improved dissolution and cleaning characteristics together with excellent tablet integrity and strength.

A multi-phase detergent tablet for use in a washing machine, the tablet comprising: a) a first phase in the form of a shaped body having at least one mould therein; and b) a second phase in the form of a compressed body adhesively contained within the mould, wherein the tablet composition comprises one or more detergent actives which is predominantly concentrated in the second phase, and wherein the second phase additionally comprises a binder. The multi-phase tablets provide improved dissolution and cleaning characteristics together with excellent tablet integrity and strength.

A multi-phase detergent tablet comprising: a) a first phase in the form of a shaped body having at least one mould therein; and b) a second phase in the form of a compressed, body adhesively contained within the mould, wherein the tablet composition comprises one or more detergent actives which is predominantly concentrated in the second phase, and wherein the second phase additionally comprises a disrupting agent. The multi-phases tablets provide improved dissolution and cleaning characteristics together with excellent tablet integrity and strength.
