• E 100 46 469.6-41 describes multi-phase soaps, in which the individual phases of the soap are clearly visible in the top view and in the side view, their manual production and their application properties. A continuous manufacturing process for these multi-phase soaps is not described.
• US-A 5 198 140 describes the continuous production of a toothed soap with increased strength.
• the simultaneous extrusion of two soap strands through an extrusion head creates a soap strand interlocked in the horizontal direction.
• Subsequent, single cutting of the soap bar into pieces and final punching results in horizontally divided soap bars.
• EP-A 0366 209 describes the production of horizontal multiphase soaps by means of a casting process. Casting processes are only suitable for the production of small quantities but not for the production of soaps for the mass consumer market.
• EP-A 0 594 077 describes the production of spiral multi-phase soaps which are produced by using a special compression head after radial rotation of the soap strand. In particular when using different soap bases, the stability of the soap type will be limited by the many phase limits in the application.

By using the casting process, a two-phase soap is created, which is not suitable for the mass consumer market due to the complex production.
