Abstract

A multi-phase laundry 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 said mould, wherein the tablet composition comprises one or more detergent actives, the second phase additionally comprises a binder, the first and second phases are in a weight ratio of at least 6:1, and the tablet is such that differential dissolution of the phases occurs in use. The multi-phase tablets provide improved dissolution and cleaning characteristics together with excellent tablet integrity and strength.
