Zusammenfassung: | A cleaning tablet has several discrete regions with differing compositions. At least one first region of the tablet is a smooth region (R1) and at least one of the other regions (R2) is in contact with (R1). (R1) And (R2) are attached to each other by attaching one of their main outer sides such that the contact area between (R1) and (R2) is less than 55% of the main outer side of (R1). An independent claim is included for preparation of the cleaning tablet involving: (1) compression of particulate composition to form a pre-compressed tablet forming (R2); (2) production of a smooth tablet forming (R1) by casting or extrusion of a smooth material; and (3) assembling the final tablet by combining the pre-compressed tablet and the smooth tablet, preferably under a mild compression force. |
