Definitions

• the present invention relates to a method for producing a novel bar soap.
• a particularly aesthetically pleasing soap consists of two halves of the same size but different colors; their manufacture is the subject of DE-B-2 049 268.
• Soaps have also become known which contain a smaller piece of soap, usually in a color which contrasts with the color of the base body, embedded in a base body made of soap mass; such soaps and their preparation are described for example in DE-A-1 617 253 and 1 617254.
• DE-C-932 624 already describes soap pieces composed of several piled and colored soap parts, which are characterized in that the parts worked on each other are not only different in color and smell, but also in consistency and by time separately worked side parts are held in such a way that when the pieces are subsequently pressed, the inner soap part pushes itself to the edge of the outer soap parts and is said to result in a usable, uniform multi-color soap.
• These soap bars consist of several (according to the sketches at least three) parts of approximately the same size, which are to be produced separately and assembled after production.
• the individual soap parts are mechanically coupled one behind the other by strongly undercut grooves and springs.
• the extrusion of the various soap parts is carried out at different times ("at least six hours earlier"); the different colored soap parts are kept as supple and warm as possible by adding lanolin and pure bee honey.
• inlay the smaller piece of soap to be stored was pressed into the cavity provided on the top of the base body, a deformation of the inlay was frequently observed, which prevented it from being connected exactly to the base body and also led to an unsightly and irregular surface design.
• the viscosity of the two soap compositions to be processed is adjusted by regulating the temperatures so that only the outer (main) soap body flows during the pressing process, while the smaller soap body to be inserted remains fixed and is thereby firmly enclosed by the outer soap body and thus one forms a firm connection with it.
• the temperature for the extrusion of the soap bodies is kept at 35 to 45 ° C, preferably around 40 ° C, and the secondary soap body at Exit from the extrusion press is cooled to 25 to 35 ° C., preferably about 30 ° C., and then pressed into the cavity of the main soap body provided for this purpose.
• the insertion of the smaller soap bar into the cavity of the basic soap body can be optimally solved if both the smaller soap bar to be stored itself and the cavity of the basic soap body intended for receiving the same are conical.
• the soap bars can have any shape, for example round or oval, the smaller soap bar used can in principle also have any desired shape.
• the cavity of the main soap body provided for receiving the soap bar to be inserted can, but need not, be arranged symmetrically in its surface; i.e. it can be in the middle of it or outside it.
• soap bars corresponds to that usually used for this purpose;
• soaps therefore means both alkali salts of higher fatty acids alone and so-called surfactant soaps, which contain the usual additives.
• surfactant soaps which contain the usual additives.
• it is based on the information in Ullmann's encyclopedia of industrial chemistry. 3rd edition, volume 18, pp. 355-395 (1967, Urban & Schwarzenberg, Kunststoff-Berlin-Vienna) as well as the monograph by D. Osteroth, «Cosmetics Feinseife »(1972, Hüthig-Verlag, Heidelberg).
• the basic soap body blanks are now fed to a punching device, where the cavity intended for receiving the secondary soap body is punched out of the surface.
• a punching device In an insertion device, the parallel soap bars preformed in accordance with the cavity punching are inserted into the recess of the base soap bars and the assembled soap bars obtained in this way are pressed or stamped in a manner known per se.
• an embossing of the cavity floor can optionally be carried out in order to obtain soap bars which, after partial use, that is to say after washing the surface, make the embossed symbol visible again.
