Description

Continuous manufacturing process for multiphase soaps

The invention relates to continuous production processes for multiphase soaps, in which the individual phases of the soap are clearly visible in the top view and in the side view.

L) 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. DE-A 1 924 980 describes a method for producing a multi-phase soap with one or more jackets which enclose a core.

The same applies to soaps that are produced according to JP 62/48799. A multi-layer round strand is created here.

Soaps are also known, with a vertical cut in the transverse or in the longitudinal direction of the soap, which separates the two soap phases (e.g. JP 1/247499). With this type of soap, both phases are visible at the same time. However, the vertical type of soap in use by the consumer and with progressive storage shows the decisive disadvantage of the lower stability of the entire soap bar. Due to the small and straight contact areas, a vertically cut soap can break simply by falling off the soap.

EP-A 0 545 716 describes the production of a multi-dimensionally curved two-phase soap. 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. With this type of soap, no pressure is subsequently applied in the form of a die cut.

Marbled soaps are also known (DE-A 2455 982, DE-A 2431 048 and DE-A 1 953 916). Here, differently colored soap phases are intensively mixed together using special press cylinders or screw presses, so that a marbled effect is created. Furthermore, the color can also be injected into the soap stream during the manufacture of the soap. These are soaps that consist of one phase.

Another multi-colored single-phase soap is described in US-A 4435 310. Here a multi-colored sinusoidal soap is obtained from one piece by injecting color during the manufacture of the soap strands and by manually turning the extrusion head. Production of Toilet Soap (D. Osteroth, pp. 76-77, ISBN 3-921956-55-2) describes the cutting of soap bars using a cutting machine, the knives of which are attached to a continuous conveyor belt. Due to the continuous movement of the soap strand, the individual knives are driven into the soap strand and cut it. The cut is made perpendicular to the soap strand at an angle of 90 °. The individual soap sections are then pressed into soap bars in a punch. In this version of the cutting machine, only an angle of 90 ° can be set for the knives by mounting the conveyor belt. Other cutting angles are not possible.

The object of the present invention was to develop a continuous production process for multi-phase soaps of the transverse and longitudinal types (Figs. 1 and 3), in which the individual phases of the soap are clearly visible in top view and in side view. When used, the multi-phase soaps should have a stability comparable to that of the single-phase soap.

The invention therefore relates to a continuous production process for multi-phase soaps of the transverse and longitudinal types, consisting of two or more separately extruded phases, characterized in that the mutual warping resulting from the punching of multi-phase soap blanks brings about a high stability of the finished soaps and the individual separate phases of the multiphase soaps obtained are clearly visible in the top view and in the side view.

Furthermore, several variants of the method according to the invention were developed.

The multi-phase soaps from the production processes according to the invention have a disproportionate strength which almost corresponds to the stability of a single-phase soap and which does not break in daily use. Continuous production processes for multiphase soaps are particularly preferred, in which each phase in the vertical, longitudinal and transverse projection is visible to at least 15% based on the total projected area.

Continuous production processes for multiphase soaps are particularly preferred, in which each phase in the vertical, longitudinal and transverse projection is visible at least 20% based on the total projected area.

In a further special embodiment of the production method according to the invention, the adjoining multiphase soaps are adjacent

Phase surfaces cut diagonally and arched against each other. Warping is achieved in continuous production by applying pressure. Multi-phase soaps with warped interfaces are particularly stable.

In the continuous production process for multiphase soaps according to the invention, phases which have a different composition are preferably used.

Soap phases in the sense of the invention consist of soap bases and other additives or ingredients.

The soap bases for the manufacturing process for multiphase soaps are known per se (Soaps and Detergents, Luis Spitz, ISBN 0-935315-72-1 and Production of Toilet Soap, D. Osteroth, ISBN 3-921956-55-2). For example, soap bases such as alkali soaps consisting of animal and / or vegetable

Substances, syndets consisting of synthetic surfactants or combinations of both can be used for multiphase soaps.

The soap composition can contain, for example, perfume oils, cosmetic ingredients, dyes and other additives as further ingredients. Examples of fragrances contained in the perfume oils for the multiphase soaps according to the invention can be found, for example, in S. Arctander, Perfume and Flavor Materials, Vol. I and II, Montclair, NJ, 1969, Selbstverlag or K. Bauer, D. Garbe and H. Surburg , Common Fragrance and Flavor Materials, 3 ^rd . Ed., Wiley-VCH, Weinheim 1997.

The perfume oils are generally added to the soap base in an amount of 0.05 to 5% by weight, preferably 0.1 to 2.5% by weight, particularly preferably 0.2 to 1.5% by weight, based on the soap base.

The perfume oils can be added in liquid form, undiluted or diluted with a solvent for perfuming the soap base. Suitable solvents for this are e.g. Ethanol, isopropanol, diethylene glycol monoethyl ether, glycerin, propylene glycol, 1,2-butylene glycol, dipropylene glycol, diethyl phthalate, triethyl citrate, isopropyl myristate etc.

Furthermore, the perfume oils for the multiphase soaps according to the invention can be adsorbed on a carrier which ensures both a fine distribution of the fragrance substances in the product and a controlled release during use. Such supports can be porous inorganic materials such as light sulfate,

Silica gels, zeolites, gypsum, clays, clay granules, gas concrete etc. or organic materials such as wood and cellulose-based substances.

The perfume oils for the multiphase soaps in the production process according to the invention can also be microencapsulated, spray-dried, present as inclusion complexes or as extrusion products and added in this form to the soap base composition to be perfumed.

If necessary, the properties of the perfume oils modified in this way can be coated with suitable materials with a view to a more targeted fragrance-free Settlement can be further optimized, for which purpose wax-like plastics such as polyvinyl alcohol are preferably used.

Cosmetic ingredients for the multiphase soaps according to the invention are known per se (Soaps and Detergents, Luis Spitz, ISBN 0-935315-72-1 and Production of

Toilet Soap, D. Osteroth, ISBN 3-921956-55-2). For example, the following cosmetic ingredients are mentioned:

Cooling agents such as Menthol and menthol derivatives, warming agents such as Capsaicin, UV filter such as Neo Heliopane® to protect against discoloration of the

Soap or protection against sun exposure on the skin, vitamins such as Vitamins A and E for vitalizing the skin, vegetable waxes and oils such as Cocoa butter, almond oil, avocado oil and jojoba oil to improve the feeling on the skin, herbal extracts, moisturizers, minerals, anti-dandruff agents such as Crinipan®, active ingredients such as deodorant ingredients soda, triclosan and triclocarban.

The following additives are also known: dyes such as Titanium dioxide, the addition of stabilizers such as DTPA and EDTA, the addition of antioxidants such as BHT, the addition of fillers such as Starch and cellulose, the addition of

Hardeners such as Sodium chloride and sodium sulfate.

As a preferred embodiment of the method according to the invention, a method AI for the continuous production of multi-phase soaps of the transverse type (FIG. 1) was found, which is characterized in that after pilling,

Homogenize or knead two or more simultaneously extruded soap strands from different soap phases, each with cuts diagonally to the soap strand at an angle of 20 ° to 70 °, the cuts are mutually joined to form a soap strand, the soap strand is cut vertically at an angle of 90 °, and then the diagonal interfaces below Pressure, so that there is a warp at the interfaces (Fig. 2).

In the process A1, the diagonal cut, then the 90 ° cut and then the soaps are preferably combined before the punching (process A2).

Furthermore, in method A1, the 90 ° cut, then the diagonal cut and then the joining of the soaps before the punching can preferably be carried out (method A3).

Furthermore, a method B for the continuous production of multi-phase soaps of the cross-type (Fig. 1) was found, which is characterized in that after pithing, homogenizing or kneading the soap phases, two soap strands from different soap phases are extruded together with a contact surface through a mouthpiece ( Fig. 9), whereby the contact surfaces are rotated from the vertical by an angle of 20 ° to 70 ° in the longitudinal axis, then the two assembled soap strands are cut at an angle of 90 °, the soap blanks obtained by 90 ° horizontally are rotated and then the contact surfaces of the individual soap phases are connected by punching under pressure, so that a curvature arises at the interfaces

(Fig. 2).

It is further preferred if, after cutting the soap strand, the subsequent connection under pressure is carried out directly by suitable arrangement of the die even without the rotation of the soap blanks.

Furthermore, a process CI for the continuous production of

Multi-phase soaps of the longitudinal type (Fig. 3) were found, which are characterized in that after pilling, homogenizing or kneading the soap phases, two soap strands from different soap phases are extruded together with vertical contact surfaces through a mouthpiece, which joined the two Soap strips are cut at an angle of 90 °, the cut pieces are rotated from the vertical by an angle of 20 ° to 70 ° in the longitudinal axis and then the contact surfaces of the individual soap phases are connected under pressure, so that a curvature arises at the interfaces ( Fig. 4).

Alternatively, in process CI, after the pilling, homogenizing or kneading of the soap phases, the extrusion of the two individual soap strands can be carried out rotated from the vertical by an angle of 20 ° to 70 ° in the longitudinal axis. Then the soap strand is cut at an angle of 90 ° and then the contact surfaces of the individual soap phases are connected under pressure, so that a curvature arises at the interfaces (method C2).

The multiphase soaps produced by the method according to the invention are described in their design in DE 10046469.6-41 and can be used as examples, but not by way of limitation, for a rounded standard soap shape with a length of 7.4 cm, a height of 1.8 cm and a width of 5.4 using FIGS. 1 and 3 cm are explained: Figures 1 and 3 show the multi-phase soap in perspective view and in supervision. The different phases are marked with 1 and 2. Figures 2 and 4 also show the warping of both phases in top and side views.

The multi-phase soaps of the transverse and longitudinal types can be produced effectively and inexpensively in large quantities by the continuous processes A, B and C according to the invention and are highly stable. production method

The production of soap masses is known (Soaps and Detergents, Luis Spitz, ISBN 0-935315-72-1 and Production of Toilet Soap, D. Osteroth, ISBN 3-921956- 55-2).

The multiphase soaps are produced as described in process A by Figure 5 and in processes B and C by Figure 8 as an example: First, the soap bases (Figs. 5 and 8, step 1) with the additives described above such as Perfume oil, cosmetic ingredients,

Dyes, stabilizers and other additives are added and then pelletized or homogenized with various rollers or kneaders (Fig. 5 and 8, step 2).

Method A for the transverse type: after homogenization, the two different soap compositions, which can differ in the composition of the soap composition itself and in at least one of the additives mentioned above, are extruded simultaneously (Fig. 5, step 4). Depending on the extruder or screw press used and the soap masses, different jacket temperatures can be used.

Alternatively, various liquid additives can also be added to the soap mass at a later point in time by metering in via nozzles (Fig. 5, step 3).

The soap bars obtained in this way are continued in parallel on two or more conveyor belts (Fig. 5, step 5).

In contrast to the usual cutting angle of 90 °, the soap strands obtained at the same time are first cut diagonally at an angle of 20 ° to 70 ° according to the later soap shape and design type (Fig. 5, step 6). The two soap bars are cut diagonally by two or more separate or by a combined cutting device.

The soap bars are divided diagonally by a knife that moves up and down or back and forth, which is guided diagonally vertically or diagonally horizontally to the soap bar.

The diagonal cut of the soap strand is preferably carried out using a continuous conveyor belt with diagonally attached knives (Fig. 6). The conveyor belts run on two oppositely positioned cones, which ensure straight and trouble-free deflection of the knives. The angles of the two cones are determined by the angular position of the knives relative to the soap bar. As a result of the cutting, soap bars in the shape of a parallelogram are obtained.

To cut the soap strand, the conveyor belts are guided over appropriately positioned deflection rollers. The precise cutting of the knives is guaranteed by the safe guidance on the conveyor belt and on the rotating cones.

The cutting angle of the knife to the soap bar can be changed flexibly by the position of the knife on the conveyor belt and by the angle of the rotating cones. This special technical feature enables the clean cutting of soap bars in large quantities.

The knives can be driven either by driving the soap strand or by a direct drive. With direct drive, the speed of the knives is synchronized with the advance of the soap bar. It is preferred if the soap bar is cut by knives that are located on a roller. The size and position relative to the soap strand ensures clean cutting.

It is preferred if the soap strand is cut by knives attached to a rotating disc (Fig. 5, step 6). The disc is positioned at an angle to the direction of transport of the soap strand in order to maintain the oblique cut. The speed of rotation is synchronized with the speed of the conveyor belt in order to obtain cuts of the desired length.

It is further preferred if the soap strand is divided by targeted diagonal punching, by cutting with a wire or by other methods. The suitable storage of the soap bar e.g. safe cutting guaranteed by concave shells.

In all of the methods A used, the soap strand is divided diagonally to the axis of the soap strand at an angle of 20 ° to 70 °, in particular 25 ° to 60 ° and in particular 30 ° to 50 °.

The alternating merging of the cuts of the two individual

Soap bars are preferably made by combining electricity (Fig. 5, step 7), in which the diagonal cut surfaces of the individual sections are precisely guided to each other and, if necessary, lightly pressed on.

It is preferred to bring the cut pieces together by moving e.g. With

With the help of vacuum suction cups. Both individual and several cut pieces are lifted from the first two conveyor belts and placed on a third conveyor belt. This conveyor belt, which is synchronized with the first two conveyor belts, runs at approximately twice the speed. The third conveyor belt can be flat or slightly curved and preferably has depressions or edges in which the cut pieces are held.

It is further preferred that the individual cut pieces are brought together by electricity diverters, e.g. Metal sheets that are at a flat angle to the

Conveyor belt stand and divert the cut pieces to another conveyor belt. The new conveyor belt must run at least twice the speed of the first two conveyor belts. The double speed of the third conveyor belt creates a gap between the cut pieces of the first conveyor belt, into which the cut pieces of the second conveyor belt are then inserted. The third conveyor belt can be flat or slightly curved and preferably has depressions or edges in which the cut pieces are held.

To improve the adhesion of the individual cut pieces, the cut surfaces can also be fixed with a fixation such as with an adhesive or with warm or liquid soap. After joining and tying or cooling, the connection becomes firm. The setting or cooling can be influenced by suitable temperature control.

When using an adhesive, make sure that no residues are left when washing the soap, for example through the use of water-soluble adhesives.

Then a second cut of the newly combined soap bar is carried out with the usual one

Angle of 90 ° corresponding to the length of the later soap bar (Fig. 5, step 8). Alternatively, the cut can be shifted from the center. In this way, at the end of the process, a bar of soap with individual soap phases of different sizes is obtained. It is also preferred if the individual soap strands are first cut diagonally at an angle of 20 ° to 70 °, then cut again at an angle of 90 ° and then combined to form a soap strand or the desired cylindrical soap blanks.

It is further preferred if the individual soap strands are first cut at an angle of 90 °, then cut again diagonally at an angle of 20 ° to 70 ° and then combined to form a soap strand or the desired cylindrical soap blanks.

The newly formed cylindrical soap blanks, which consist of different soap phases, are then pressed into the final shape by horizontal or vertical stamping or pressing (Fig. 5, step 9). Alternatively, the cylindrical bar of soap can be rotated and then punched. Before punching, the precise positioning of the two cut pieces or the entire soap blank in the die is important. This can e.g. through the appropriate choice of guides and brackets that press the sections against each other, both before and during the punching process.

The cut and combined soap strands are usually punched individually to the soap bars in rotating disk punches or to several in so-called flash stamping systems (Soaps and Detergents, Luis Spitz, pp. 193-204, ISBN 0-935315-72-1).

Depending on the type of soap stamping machine used, the punching process takes place with different contact weights or contact pressures. Depending on the nature and composition of the soap mass, different temperatures are used in the stamping process.

The protrusions or pinch edges that occur during punching are cut with the help of knives or guides (Fig. 7) during the actual punching process separated from the soap bar. Both the pure soap masses and a mixing phase are separated by the appropriate arrangement of the knives. The two pure soap phases are then returned to the manufacturing process. For the die according to Figure 7, there is a mixing phase of approx. 1% based on the total soap mass used in the first step.

This mixing phase can either be processed into a separate soap or, in the case of a two-tone soap, colored and also reused.

Alternatively, two or more diagonal soap sections obtained from the first diagonal section can be pressed individually in a horizontal punch after the mutual joining. As a result, the soap strand is continuously punched out. The protruding cut edge of the two diagonally cut pieces is then also separated and can be returned to the process.

Finally, the soap bars obtained are cooled to normal temperature in cooling systems.

Method B for the transverse type: After homogenization, the two different soap compositions, which can differ in the composition of the soap composition itself and also in at least one of the additives mentioned above, are extruded into a soap strand by common extrusion (Fig. 8, step 4).

Alternatively, various liquid additives can be added to the soap mass at a later point in time by metering in via nozzles (Fig. 8, step 3).

First, the two soaps are put into individual e.g. semicircular extrusion tubes preformed into partial soap strands, in a common e.g. round

Extrusion tube brought together and then extruded through a mouthpiece (Fig. 9). This creates a longitudinally divided soap strand, in which the soap phases are already connected to one another by the common extrusion.

By rotating the semicircular extrusion tubes of the partial soap strands or by rotating the partition between the partial soap strands from the vertical by an angle between 20 ° and 70 ° with respect to the longitudinal axis, one soap strand rotated with respect to the two soap phases is obtained (Fig. 9).

It is preferred if the partition between the two individual extrusion tubes is a straight wall. It is further preferred if the partition has a wave shape adapted to the later soap shape or an irregular shape. It is further preferred if the dividing wall is rotated in itself, thereby rotating the soap strands from the vertical.

It is preferred if the individual extrusion tubes are semicircular and the common one

Extrusion tube and the mouthpiece are round in their geometric shape. Alternatively, the individual extrusion tubes can be semi-oval and the common extrusion tube and the mouthpiece can be oval. It is further preferred if the individual extrusion tubes are square or rectangular and the common extrusion tube and the mouthpiece are rectangular or square. Further

Combinations of round, semicircular and square extrusion tubes are possible.

The width and height of the mouthpiece is determined by the design of the finished soap bar. In a special embodiment, the width of the mouthpiece corresponds to the length of the finished soap bar. Depending on the design of the finished soap, the width of the mouthpiece is larger or smaller than the length of the die. In general, the volume of the blank soap must be larger than the volume of the die.

During extrusion, depending on the extruder used or

Screw press and the soap masses used different jacket temperatures become. The extruded soap strand then consists of two partial strands which are connected to one another at a diagonal contact surface.

The soap strand is then cut according to the size and shape of the finished soap bar at an angle of 90 ° using methods known per se.

The length of the section is determined by the design of the finished soap bar. In a preferred embodiment, the length of the section corresponds to the width of the finished soap bar.

Then the soap blanks are rotated 90 ° horizontally and through

Stamping or pressing brought into the final shape. The stamping of the soap blanks to the soap bars is usually carried out individually in rotating disc punches or else in so-called flash stamping systems (Soaps and Detergents, Luis Spitz, pp. 193-204, ISBN 0-935315-72-1).

The punching or pressing of the soap bar is also preferably done without prior rotation of the soap tube. The die is then guided in the punch at a right angle to the soap bar.

The protrusions or pinch edges that occur during punching are separated from the soap bar with the help of knives or guides (Fig. 7) during the actual punching process. Both the pure soap masses and a mixing phase are separated by the appropriate arrangement of the knives. The two pure soap phases are then returned to the manufacturing process. For the die according to Figure 7, there is a mixing phase of approx. 1% based on the total soap mass used in the first step. This mixing phase can either be processed into a separate soap or, in the case of a two-tone soap, colored and also reused.

Method C for the longitudinal type: After homogenization, the two different soap masses, which can differ in the composition of the soap mass itself and in at least one of the additives mentioned above, are extruded into a soap strand by joint extrusion (Fig. 8, step 4).

To do this, the two soap masses are first vertically semicircular extrusion tubes pre-formed into partial soap strands, in a common e.g. round extrusion tube and then extruded through a mouthpiece (Fig. 9). This creates a vertically longitudinally divided soap strand in which the soap phases are already connected to one another by the common extrusion.

Alternatively, by rotating the semicircular extrusion tubes for the soap bars or by rotating the partition between the

Obtain partial soap strands from the vertical by an angle between 20 ° to 70 ° with respect to the longitudinal axis and a soap strand turned from the vertical with respect to the two soap phases.

It is preferred if the partition between the two individual extrusion tubes is a straight wall. It is further preferred if the partition has a waveform adapted to the later soap shape or an irregular shape.

It is preferred if the individual extrusion tubes are semicircular and the common extrusion tube and the mouthpiece (Fig. 9) are round in their geometric shape. Alternatively, the individual extrusion tubes can be semi-oval and the common extrusion tube and the mouthpiece can be oval. It is further preferred if the individual extrusion tubes are square or rectangular and the common extrusion tube and the mouthpiece are rectangular or square. Other combinations of round, semicircular and square extrusion tubes are possible.

Depending on the extrader or screw press used and the soap masses, different jacket temperatures can be used in the extrusion.

In the case of a vertically divided soap bar, the soap bar is first cut at an angle of 90 ° to the individual soap blanks and then before or during the punching of the soap bar by an angle of 20 ° to 70 ° with respect to the longitudinal axis of the soap bar.

Depending on the type of soap stamping machine used, the punching process takes place with different contact weights or contact pressures. Depending on the nature and composition of the soap mass, different temperatures are used in the stamping process. The protrusions or pinch edges that occur during punching are separated from the soap bar with the help of knives or guides (Fig. 10) during the actual punching process. Both the pure soap masses and a mixing phase are separated by the appropriate arrangement of the knives. The two pure soap phases are then returned to the manufacturing process. For the die according to Figure 10, depending on the angle used, there is a mixing phase of approx.1.5% based on the total soap mass used in the first step.

This mixing phase can e.g. either processed into a separate soap or in the case of a two-tone soap e.g. can be colored and also reused.

Formulations for different types of soap

For the production of multiphase soaps using the manufacturing process according to the invention, the following soap bases can be used, for example: Alkaline soaps, syndets or combinations of both can be used.

The water content of the individual soap formulations must be taken into account for all combinations of soap bases. Due to the different shrinkage of the individual soap formulations, it can be separated at the

Contact surface and thus break the soap. Furthermore, different soap formulations can have different washing-up behavior. By suitably adjusting the water content, the soap raw materials and other additives in the individual soap formulations and by using the production processes according to the invention, numerous combinations can tions of soap formulations for the production of stable multiphase soaps.

Since these so-called solid skin cleansing agents can also be made transparent or opaque due to various additives and a special manufacturing process, a wide variety of combinations, including colored ones, can be produced.
