发明名称 TABLET DETERGENT COMPOSITIONS
摘要 A tablet of compacted particulate detergent composition has an indentation (39) around a periphery of the face (37) of the tablet. The surface circumscribed by the indentation preferably has higher permeability and is rougher than the surface of the indentation (39) itself. Such a tablet can be made by a process in which a detergent composition is compacted in a mould by at least one die with an elastomeric surface layer (36) on an area which contacts the composition, which layer (36) is surrounded by a rigid rim (30) which forms the indentation (39).
