ABSTRACT:
A lavatory cleansing block has two parts co-extruded together, the first part containing a chlorine releasing bleach and the second part containing component such as a perfume or colorant which need not be bleach resistant. Migration of components is avoided if there is no common hydrophobe in the two parts. The perceived performance of the perfume is enhanced by its juxtaposition with the bleach.
