"A MUILTIPHASE SOAP COMPRISING TWO OR MORE PHASE AND PROCESS FOR THE PREPARATION THEREOF"

Abstract A soap comprising two or more phases, wherein said two or more phases are visible when viewed from above and from the side, wherein said two or more phases are diagonally cut, wherein the individual phase is cut at an angle of 14° to 70°, and wherein the points of intersection of said phases are joined under pressure so that cambering arises at said points of intersection.
Full Text The invention relates to multiphase soaps in which the individual phases are clearly visible when viewed from above and from the side, to their preparation and to their use for applying various scent sensations during the washing operation
The preparation and use of picture and changing motif soaps is described in DE-A 3145813 The preparation takes place by stamping various horizontal soap layers that have been prepared by means of an extruder This method cannot be operated economically and therefore the use of these soaps in the mass consumer market is not possible A particular disadvantage of this type of horizontally cut soap is the fact that the various horizontal soap layers cannot be distinguished or can be distinguished only with great difficulty by the consumer when viewed from a customary viewing angle of about 45° and more This effect intensifies as the period of use increases since the two phases become thinner as a result of washing away
This disadvantage also applies to the diverse horizontally cut soaps described in EP-A 0 366 209 and US 5,198,140. The preparation of an interlocked soap having increased strength is described in US 5,198,140 The preparation of horizontal multiphase soaps by a casting process is described in EP-A 0 366 209. Casting processes are suitable only for the preparation of small numbers of bars, but not for the production of soaps for the mass consumer market
The preparation of spiral-shaped multiphase soaps which are prepared by the use of a special compression head after radial rotation of the soap strand is described in EP-A 0 594 077 Especially when different soap bases are used, the stability of the type of soap is limited in its application by the many phase boundaries
A method for the preparation of a multiphase soap with one or more sheaths which surround a core is described in DE-A 1 924 980 The consumer is not able visually to distinguish this type of soap from a normal single-phase soap before use and also in the interim during use, as a result of which there is no advantage from the standpoint of application technology
This also applies analogously to soaps prepared in accordance with JP-A 62/48799 Here, a multi-layer round strand is produced.
Soaps in which a vertical cut in the transverse direction or in the longitudinal direction of the soap which (sic) separates the two soap phases are also known (e g., JP 1-247499) In this type of soap, both phases are visible at the same time However, when in use by the consumer and as storage progresses, the vertical type of soap exhibits the decisive disadvantage of lower stability of the entire bar of soap. Because of the small and straight contact areas, a vertically cut soap can break even as a result of the soap simply falling to the ground. Especially when different soap formulation (sic) are used for the individual parts of the soap, shrinkage and drying out can lead to breaking of the soap Also, when different soap formulations are used, the strength of the diagonally cut soap, in contrast to that of vertically joined soap, is ensured throughout the entire period of use when the soap is used by the consumer. As a result, in the future less expensive soap formulations can also be combined with more expensive soap formulations, or different soap
formulations which are incompatible with one another because of shrinkage can be combined for the preparation
The preparation of a multidimensionally curved two-phase soap is described in EP-A 0 545 716 By using the casting process, a two-phase soap is produced, which is not suitable for the mass consumer market due to the costly preparation. Since this soap is a cast soap where no pressure is subsequently exerted in the form of stamping, the keeping qualities of this type of soap are limited in daily use
Marbled soaps are also known (DE-A 2 455 982, DE 2 431 048, US 1 587 430 and DT 1 953 916) Here, differently coloured soap phases are mixed intensively with one another using special pressing cylinders or screw presses, such that a marbled effect is produced. Furthermore, the colour can also be injected into the soap stream during the preparation of the soap These soaps are soaps that consist of one phase
A further multicoloured single-phase soap is described in US 4,435,310 Here, by injecting colour during the preparation of the soap strands and by manually turning the extruder head, a multicoloured sinusoidal soap in one piece is obtained
Multiphase soaps in which the various phases can have different ingredients and which, during use, have a stability comparable with that of a single-phase soap were the aim of the present invention In particular, it was to be possible for the different phases to comprise different perfume oils so that, during use, different successive scent sensations are possible.
Multiphase soaps consisting of two or more phases have been found which are characterised in that these phases are clearly visible when viewed from above and from the side
The multiphase soaps according to the present invention exhibit overproportional strength, which virtually corresponds to the stability of a single-phase soap
Multiphase soaps in which each phase is at least 15% visible in the vertical, longitudinal and transverse projection, based on the total projected surface, are particularly preferred
Multiphase soaps in which each phase is at least 20% visible in the vertical, longitudinal and transverse projection, based on the total projected surface, are especially preferred
In a particular embodiment of the multiphase soaps according to the present invention, adjacent phase surfaces are cut diagonally and cambered towards one another. The cambering is achieved during the preparation by applying pressure. Multiphase soaps with cambered interfaces have particular stability
The multiphase soaps according to the present invention preferably consist of two phases which differ in composition
In general, the multiphase soaps according to the invention can be used for all washing purposes, in particular for washing purposes where an output of more than one ingredient is desired Here the output can take place simultaneously or successively in a targeted manner
In particular, it is advantageous that each phase of the multiphase soap can be tailored to the particular preferred application The particular soap phase can be configured by means of the composition of the soap base and optionally further additives or fillers as a medium that is best for the application concerned Thus, for example, the conditions for ingredients
can be optimised by means of pH, ionic strength, water content, fat content, fat composition and similar parameters
The multiphase soaps according to the invention can be used, for example, for washing or cleaning skin, hair, textile, plastic, metal, wood, ceramic, glass, composites and the like
The soap bases for the multiphase soaps according to the invention are known perse (Soaps and Detergents, Luis Spitz, 0-935315-72-1 and Production of Soap, D. Osteroth, 3-921956-55-2) For example, soap bases such as alkali metal soaps consisting of animal and/or vegetable substances, syndets consisting of synthetic surfactants or combinations of the two can be used for the multiphase soaps according to the invention
The use of natural vegetable soap raw materials, such as, for example, glycerol, castor oil, coconut oil, olive oil, palm oil, palm kernel oil, peanut oil, almond oil, oil of ncinus, cocoa butter, poppy oil, maize oil, hemp oil, soya bean oil, rapeseed oil, cottonseed oil and sunflower oil is preferred
The use of natural animal soap raw materials such as, for example, pork fat, beef tallow, sheep tallow or fish oil is preferred.
The said oils and fats consist of triglycerides of straight-chain saturated, mono- and polyunsaturated acid having six to thirty carbon atoms The sodium and the potassium soaps are preferably prepared from these soap raw materials by saponification.
The use of synthetic soap raw materials such as, for example, alkyl sulphoacetates, sulphosuccinates, monoglycende sulphates, acyl isethionates, glyceryl ether sulphonates, alkylsulphonates, ether sulphonates, acylsulphonates or alkylacyl sulphonates is preferred.
It is also possible to use agents for adjusting a pH value or the ionic strength. Examples which may be mentioned are sodium carbonate, sodium hydroxide, phosphoric acid and salts thereof, sodium acetate, acetic acid, citric acid and salts thereof, sodium bicarbonate, triethanolamine, EDTA, disodium EDTA and tetrasodium EDTA
It is, of course, known to those skilled in the art that cosmetic preparations are in most cases inconceivable without the customary auxiliaries and additives These include, for example, agents imparting body, fillers, perfume, dyes, emulsifiers, additional active compounds, such as vitamins or proteins, screening agents, stabilisers, insect repellents, alcohol, water, salts, and substances having an antimicrobial, proteolytic or keratolytic action
The multiphase soaps can contain, for example, perfume oils, cosmetic ingredients, active compounds, dyes and further additives as further ingredients The multiphase soaps can contain one or more of the ingredients
Ingredients which can be present in the multiphase soaps according to the invention can give rise to additional effects. Examples which may be mentioned are preservatives, abrasives, anti-acne agents, agents against skin aging, antibacterial agents, anticellulitis agents, antidandruff agents, anti-inflammatory agents, anti-irritants, irritation suppressants, antimicrobial agents, antioxidants, astringents, perspiration suppressants, antiseptics, antistatics, binders, buffers, carrier materials, chelating agents, cell stimulants, cleaning agents, treatment preparations, depihatones, surfactants, deodorisers, antiperspirants, softeners, emulsifiers, enzymes, essential oils, fibres, film-forming agents, fixatives, foaming agents, foam stabilisers, antifoams, foam boosters, fungicides, gelling agents, gel-

The perfume oils are generally added to the soap base in an amount of 0 05 to 5% (m/m), preferably of 0 1 to 2 5% (m/m), and particularly preferentially of 0 2 to 1.5% (m/m), 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 purpose are, for example, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerol, propylene glycol, 1,2-butylene glycol, dipropylene glycol, diethyl phthalate, triethyl citrate, isopropyl mynstate, etc
Furthermore, the perfume oils for the multiphase soaps according to the invention can be adsorbed on a carrier which serves both for fine dispersion of the fragrances in the product and also for controlled release during use. Such carriers can be porous inorganic materials, such as light sulphate, silica gels, zeolites, gypsums, clays, clay granules, gas concrete, etc or organic materials such as woods and cellulose-based substances
The perfume oils for the multiphase soaps according to the invention can also be microencapsulated, spraγ-dried, in the form of inclusion complexes or in the form of extrusion products and be added in this form to the soap base to be perfumed
The properties of the perfume oils modified in this way can optionally be further optimised by so-called "coating" with suitable materials with regard to a more targeted fragrance release, for which purpose waxy polymers such as, for example, polyvinyl alcohol, are preferably used.
The microencapsulation of the perfume oils can, for example, be carried out by the so-called coacervation method with the aid of capsule materials made from, for example, polyurethane-like substances or soft gelatine The spraγ-dried perfume oils can, for example, be prepared by spray drying an emulsion or dispersion containing the perfume oil, where the carriers used can be modified starches, proteins, dextrin and vegetable gums. Inclusion complexes can be prepared, for example, by introducing dispersions of the perfume oil and cyclodextrins or urea derivatives into a suitable solvent, e.g , water Extrusion products can be obtained by melting the perfume oils with a suitable waxy substance and by extrusion with subsequent solidification, optionally in a suitable solvent, e g , isopropanol
The fragrances can also be used in the form of precursors.

It is also possible to incorporate three-dimensional objects into the multiphase soaps For the purposes of the invention, three-dimensional
objects are objects of any shape For example, it is possible to incorporate round, oval, rectangular, square, spherical, ellipsoidal, cuboid, helical or irregularly shaped objects into soaps
In general, the three-dimensional objects can serve for advertising purposes, as toys, e g in the form of figures, for unambiguous identification of a brand, as collectable objects or as identifying object in the case of prize competitions.
The use of one or more three-dimensional objects, which consist of one or more different materials, in one, in two or more, simultaneously in several soap phases, or in one or more soap phases and simultaneously outside the soap is also preferred
These three-dimensional objects are preferably incorporated in the transparent part in order to obtain a visual experience right from the start of use of the soap It is also preferred to incorporate these three-dimensional objects into the opaque part in order to achieve a surprise effect as the soap is washed away
The incorporated three-dimensional objects should not have an adverse interaction with the multiphase soap, but can, for example, have a beneficial influence on the stability
The three-dimensional objects can be made from a very wide variety of materials. Thus, for example, the objects can be made of soap composition, plastic, metal, ceramic, wood, textiles, glass, minerals, parts of plants, leather, cardboard or paper
The use of plastics such as, for example, polyurethanes, polyethylenes, polypropylenes, polystyrenes, polyacrylates and the like is preferred

The use of normal minerals such as, for example, granite, sandstone, quartz, and also precious minerals, such as, for example, ruby, emerald, topaz, diamond or amethyst is preferred
The use of parts of plants such as, for example, flowers, leaves, fruits, seeds, roots, rinds and stems of a very wide variety of plants is preferred
The use of leathers of natural texture or of embossed leathers from, for example, snakes, crocodiles, cattle, pigs and sheep is preferred
The multiphase soaps according to the invention can be packaged in known packaging systems, such as, for example, wrappers, hard cardboard, tubes and blister packs Here the type of packaging ensures that the multiphase soap remains undamaged in shape and appearance
The packaging systems can enclose the multiphase soap either tightly or loosely. Various materials, such as paper, cardboard, plastic, textiles or wood, or combinations thereof, can be used for this purpose
The packaging systems can be flexible in their design, such as, for example, films or papers, or rigid, such as, for example, hard paper or plastic cases Combinations of flexible and rigid packaging can also be used
The multiphase soaps according to the invention can either be packaged individually or with several together In the case of several bars of soap in one packaging, the individual bars of soap can also each be packaged separately
The packaging materials can be transparent, such as, for example, plastic films, semi-transparent, such as, for example, plastic films or papers, non-transparent, such as, for example, papers or cardboards In addition, combinations of transparent, semi-transparent or non-transparent packagings are also suitable for multiphase soaps
Packaging systems for the multiphase soaps in which the multiphase nature of the bar of soap can already be discerned through the transparent, partially transparent or semitransparent packaging material are preferred In addition, packaging systems in which the bar of multiphase soap can be discerned by printing on the non-transparent packaging are prferred.
A method for the preparation of the multiphase soaps according to the invention has also been found, which is characterised in that the individual phases in the form of soap strands are cut straight diagonally at an angle
of from 14° to 70°, in particular 30 to 55°, and the cut faces are joined under pressure so that cambering results at the cut faces
The phases at the cut faces are preferably joined using a pressure of from 4 to 10 bar or with a pressing weight of 1 0 to 2.0 t. A particularly preferred cambering of the cut faces is produced under these conditions
The soap strands are prepared in a manner known per se: after the addition of additives to the soap base, milling and extrusion are carried out. Furthermore, in the case of industrial production, the additives can be added during extrusion (Soaps and Detergents, Luis Spitz, 0-935315-72-1 and Production of Soap, D Osteroth, 3-921956-55-2)
The multiphase soaps according to the present invention can be illustrated using the example in Figure 3: Figure 3 shows a perspective view and a plan view of the multiphase soap according to the invention The different phases are labelled 1 and 2. The figure also shows the cambering of the two phases.
The multiphase soaps according to the invention surprisingly have high stability and can beneficially be prepared in large bar numbers
Examples
Taking a rounded standard soap shape (Figs 1a and 1b perspective view of a standard soap) with a length of 7 4 cm, a height of 1.8 cm and a width of 5 4 cm as an example, the cut face shapes according to the present invention in the longitudinal and in the transverse direction of the multiphase soap are described below (Fig 3 transverse type centre cut, perspective view and Fig 4 longitudinal type centre cut, perspective view) This is only one application example since the various soap shapes can clearly vary in their length, height and width
A bar of soap of standard shape can be divided into two or more parts. In the sense of the invention, this division takes place in the direction of the longitudinal or transverse axis of the bar of soap at an angle of between 0 and 90°. This results in bars of soap with different types of cut (Fig. 5 transverse type centre cut, side and plan view and Fig. 6 longitudinal type centre cut, side and plan view, various angles of cut) and different ratios of the plan view surface areas of the individual soap phases The actual angle of cut is obtained as a result of the surface area ratios to be achieved, which are necessary for discerning the a (sic) individual soap phases. As a function of the ratio of the height to the length of the standard soap described of about 3 44, an angle of the cut surface between the soap phases of about 14° to 60° is then obtained for the transverse type and an angle of about 20° to 70° for the longitudinal type This new angle of cut varies depending on the shape of the soap and technically is a novel requirement for the preparation of the soap and clearly differs from the customary angle of cut of 0° (horizontal cut, Fig. 2) or 90° (vertical cut, Figs 7 and 8).
In a two-phase soap of the new diagonal type, the quantitative ratio of the two phases is identical (irrespective of the cutting direction and the angle
of cut) insofar as the cutting point passes through the mid point of the soap (Fig 5 transverse type centre cut, side and plan view, various angles of cut and Fig. 6 longitudinal type, centre cut, side and plan view, various angles of cut) If the cutting point in the case of a two-phase soap of the novel diagonal type lies outside the mid point, for example as a result of horizontal or vertical shifting of the cut surface, a bar of soap with phases of different sizes results (Fig. 9 transverse type of offset cut).
Application test:
1. Test to determine the strength of various multiphase soaps:
The mechanical strength of a soap is of importance for its suitability during daily use It is demonstrated that multiphase soaps with a diagonal cut are able to withstand greater stress than would be expected on the basis of the cut surface area and, in particular, are able to withstand greater stress than soaps with a straight vertical cut (Fig. 7/8) By means of a device (Fig. 11), fracture tests with weights were carried out on soaps of different design types and different combinations of soap formulation The device has a lever arm (5), which on one side has a plate (3) on which the weights for placing the soap (4) under stress can be placed On the other side, the lever arm is pivotably mounted The bar of soap (4) is supported by a flexible mounting (6) The device loads the bar of soap (4) in the centre in order to simulate stress in daily use, e g , simple falling to the ground The bars of soap were loaded in a chronological sequence of ten seconds in each case with weights from five kg upwards in 0 5 kg steps. Insofar as a weight was held, the soap was loaded with further weight until the soap fractures
Table Fracture stability
(Table Removed)
It can be seen that the types of soap with the diagonal design can be subjected to significantly higher loading, and that therefore there is considerably greater strength in daily use The results of the fracture tests were confirmed by consumers during daily use
2. Preference test with regard to design:
Consumer preference was carried out in a comparison test with the three types of soap: horizontal cut (Fig. 2), vertical cut (Fig. 8) and the diagonal cut according to the invention (Fig 3). Of the 100 people questioned, three of those questioned preferred the vertical cut type, four of those questioned preferred the horizontal cut type and 93 of those questioned preferred the novel diagonal cut type This means that the novel design was selected with a significance of > 99.9%
Because of the novelty of the harmonious combination of two soap phases, there is interest in an application
3. Preference test with regard to scent:
Consumer preference for scent was carried out in a comparison test with two bars of two-phase soap a bar of two-phase soap A (equal proportions by area, diagonal cut through the central point, Fig 3) with two different perfumes was compared with another bar of soap B of identical construction which had been perfumed with a 1 1 mixture of these two compositions The perfume concentration was 1 % in both bars of soap
It was found that the scent has a more intensive action in the bar of soap A containing the separate perfume oils. Both perfume oils were perceived in parallel. The scent acquires an additional dimension.
4. Formulation:
In addition to the perfume oil, soaps also contain active compounds, such as cooling substances, UV filters, antibacterial active compounds, deodorants and others These active compounds are often expensive and are therefore incorporated into soaps only in small amounts The concentration of the individual active ingredients is often below the limit for effectiveness In the novel two- or multiphase soap it is possible to incorporate such an active compounds (sic) in a targeted manner into one of the soap phases As a result of the concentration of active compounds in one part of the soap, increased effectiveness is achieved in the case of targeted application of the one soap phase.
5. Discernibility tests:
To achieve a visible effect in a multiphase soap, a certain proportion of the two phases must be discernible when the soap viewed from above or from
a customary viewing angle of about 45° Three tests for the spontaneous discernment of multiphase soaps are described below
The first soap phase is defined as the soap phase with the largest visible portion based on the area of soap projected in plan view The second soap phase is the soap phase with the second largest visible portion. The visible portion of the second and subsequent soap phases is expressed as the ratio of the projected area of the soap to the first soap phase or as a percentage of the total surface area
Tests for soaps of the new diagonal type to determine the spontaneous discernment effect of multiphase soaps, six different test groups each of 20 participants were shown the bar of soap to be assessed (colour combination green/white, Fig 3) for three seconds viewed from above from a distance of one metre. The participants were then asked about what they had seen and for the number of different soap phases. In these consumer-oriented tests, it was found that there is a very good discernment effect for the diagonal soap type (transverse type second phase at one end) if, in plan view, the ratio of the surface area of the first soap phase to that of the second soap phase is above about 5 6 1 or if the proportion of the second soap phase in the total surface area is about 15% Below a proportion of 10%, the spontaneous discernment clearly decreases (see Table "Discernment rate of multiphase soaps test 2") A poor discernment effect is found if a bar of two-phase soap with the horizontal design (Fig 2, colour combination green-white) is viewed from a viewing angle of about 45° With this type of two-phase soap, it is not possible to discern the two phases when viewed directly from above At a viewing angle of 45° a ratio of 1 12 5 or about 8% of the visible area for the second soap phase again results.

Formulation section for different types of soap
For the preparation of multiphase soaps it is possible to use, for example, alkali metal soaps, syndets or combinations of the two as soap bases In the case of all combinations of the soap bases, the water content of the individual soap formulations must be taken into consideration Because of the differing shrinkage of the individual soap formulations, separation at the contact surface and thus breaking of the soap can occur By means of suitable adjustment of the water content in the individual soap formulations and the new diagonal design it is possible to use numerous combinations of soap formulations for the preparation of stable multiphase soaps
Since these so-called solid skin-cleansing agents can, by virtue of different additives and a special method of preparation, also be prepared in
transparent or opaque form, it is possible to prepare a very wide variety of combinations, including, of course, coloured ones
Using the multiphase soaps, it is possible to prepare complementary scents which would lead to discoloration in pure white soaps In the preparation of multiphase soaps, the perfume oil constituents which can lead to discoloration are incorporated in the coloured fraction Perfume oil constituents which tend to produce turbidity in transparent soap are incorporated in the opaque or non-transparent phase

The preparation of soaps is known (Soaps and Detergents, Luis Spitz, 0-935315-72-1 and Production of Soap, D Osteroth, 3-921956-55-2) The preparation of the novel multiphase soaps was carried out as described in the following method by way of example: first of all the additives described above, such as perfume oil, cosmetic ingredients, dyes, stabilisers and further additives, are added to the soap bases and the mixtures are then milled The soap compositions were then extruded at a jacket temperature of about 22°C and a head temperature of about 45°C
The soap strands obtained in this way are cut to the soap shape The same is carried out for the soap strands of the second soap phase. The two soap strands are then cut parallel and diagonally in accordance with the subsequent cut shape and design type at an angle of from 14° to 70° Prior to the stamping operation, the soap strands prepared in this way are aligned over the soap shape. The stamping operation was carried out, depending on the type of soap stamping machine used, with a pressing weight of from about 1 0 to 2.0 t or a pressing force of from 4 to 10 bar During this stamping operation, both soap compositions have a temperature of about 40 to 50X

WE CLAIM:
1. A multiphase soap consisting of two or more phases, wherein said two or more phases are visible when viewed from above and from the side, characterized in that said soap can be prepared by a method in which the individual phases in the form of soap strands are cut straight diagonally at an angle of 14° to 70°, and wherein the points of intersection of said phases are joint under pressure so that cambering arises at said points of intersection.
2. A soap as claimed in claim 1, wherein each phase is visible in the vertical, longitudinal and transverse projection to at least 15% based on the overall projected area.
3. A soap as claimed in claim 1, wherein each phase is visible in the vertical, longitudinal and transverse projection to at least 20% based on the overall projected area.
4. A soap as claimed in claim 1, wherein each phase comprises different perfume oils, cosmetic ingredients, active ingredients, dyes and/or further additives.
5. A process for the preparation of multiphase soap as claimed in claim 1, comprising the step of diagonally cutting in the form of soap strands the individual phases at an angle of from 14° to 70°, and the points of intersection are joined under pressure so that cambering arises at the points of intersection.
6. A process as claimed in claim 5, wherein the angle is 30° to 55°, and the points of intersection are joined under pressure so that cambering arises at the points of intersection.
