A multi-phase melt cast toilet bar which has at least one interface along a plane perpendicular to the plane formed by the x and y-axis of said bar, and a process of making the bar is described. Each phase, containing a cleansing agent, is reproducibly positioned in the bar to be used simultaneously thereby allowing the user to simultaneously derive benefits from the use of the cleansing agents contained in the bar's layers. The process for making the bar is a continuous one, whereby the molten cleansing agents are simultaneously or separately poured into the mold, simultaneously or separately allowed to harden, and where the mold divider is not removed or removed either after hardening of the adjacent molten cleansing agent but before the pouring of the next molten cleansing agent, or removed while at least one phase remains flowable. The hardened multi-phase toilet bar is finally ejected from the mold.
