Abstract

A detergent tablet with a sandwich structure of at least three layers comprises: (1) two external layers comprising an antiscaling agent; and (2) an internal layer comprising a bleaching agent. The external layers dissolve faster than the internal layer and are retarding agents for the internal layer in order to pretreat the washing water against lime scale. The tablet dissolves in two steps: first the external layers, then the internal layer when the external layers are entirely dissolved. An Independent claim is also included for the manufacturing of the tablet.
