This invention relates generally to toilet articles, and more particularly to toilet articles having a plurality of layers of different materials separated by at least one pre-formed membrane. A multi-phase solid toilet article whose phases are separated by a membrane, and processes for making the article are described. Each phase is reproducibly fabricated to form an article allowing the user to sequentially or simultaneously derive benefits from the different materials contained in the article's layers. The membrane is either at least partially water soluble or dispersible in the case of a product used with water, or shearable in the case of a cosmetic product which is applied directly to or rubbed on the skin. The membrane material is selected to dissolve or disintegrate with product use, so as to accomplish its intended function of separating the different cosmetic materials until they are consumed. The flowable toilet or cosmetic formulations are simultaneously or separately transferred into the mold, simultaneously or separately allowed to harden, where the membrane divider is not removed and becomes a part of the finished product. The hardened multi-phase article is finally ejected from the mold.
