Patent ID: 7919442

Claim:
A process of preparing multiphase toilet soap, the process comprising the following steps: a—adding, in sequence, the components: i—base toilet-soap mass, opacifying agent and chelating agent, ii—at least one surfactant and emollient, iii—a chelating agent; and iv—essence and anti-oxidizing agent, in a turned-on Mixer, at intervals of at least 10 minutes between the additions of each of the above groups (i) to (iv); b—mixing for a period of time sufficient to achieve total homogenization of the components; c—introducing the mixture obtained in step b—in a roller mill according to a rolling velocity until homogenization is achieved; d—transferring, on conveyor belts, the rolled mass obtained in step c—to an Extruder and extruding it once through a preliminary Trafila to form an extruded mass of an opaque phase; e—during the preparation of the extruded mass of the opaque phase, adding a translucent phase by means of a conveyor belt that acts as a dosing equipment; f—introducing the mixture containing the opaque and the translucent phases into a final Trafila operating in an open atmospheric environment, the introducing of the mixture occurring at a temperature ranging from 60 to 80° C., and at a velocity adequate for obtaining a heterogeneous and constant product; g—introducing the extruded mass obtained in step f—in a cutter to form a cut mass; and h—molding the cut mass in a press.
