摘要:
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.

摘要:
A lavatory cleansing block is formed of a mixture comprising:(a) from 5 to 85% by weight of one or more anionic surface active agents;(b) from 2 to 50% by weight of one or more solubility control agents having a solubility in water less than that of the anionic surface active agent(s); and(c) from 0.5 to 50% by weight of one or more water-soluble salts of polyvalent metals.
摘要:
