Description

[0001] Cleaning agent preparation, process for producing a cleaning agent preparation and process for producing a cleaning agent

[0002] The invention relates to a cleaning agent preparation which is water-soluble and which contains at least a first and a second surfactant.

[0003] The invention further relates to a process for producing a cleaning agent preparation of the type mentioned at the outset.

[0004] The invention further relates to a water-soluble cleaning agent and a process for producing a water-soluble cleaning agent.

[0005] Detergent preparations, particularly as combinations of active ingredients, are used in a wide variety of cleaning products and are essential for cleaning various items, objects, and surfaces. Detergent preparations are particularly important in detergents for cleaning textiles, their precursors, and leather products. Surfactants are often used as cleaning agents, although the surfactant content in cleaning preparations is usually only 1-40% by weight, meaning the cleaning performance can be relatively low.

[0006] The production of detergent preparations and detergents, particularly those containing surfactants, is often problematic. Firstly, the surfactants must meet stringent requirements with regard to their effectiveness and degradability, and secondly, processing them into a user-friendly end product is often associated with considerable effort. Therefore, the object of the invention is to improve detergent preparations, particularly detergent preparations, and their production. Furthermore, the object of the invention is to provide an improved detergent and cleaning method.

[0007] To achieve the stated object, the features of claim 1 are provided according to the invention. In particular, to achieve the stated object, in a cleaning agent preparation of the type described above, the invention proposes that the second surfactant has a lower melting temperature than the first surfactant and that the melting temperature of the cleaning agent preparation is at least 20 °C below the melting temperature of the first surfactant. Preferably, the melting temperature of the cleaning agent preparation is at least 40 °C below the melting temperature of the first surfactant.

[0008] The melting temperatures mentioned refer to standard conditions, in particular to standard pressure.

[0009] It should be noted that according to the solution to the problem, not only the first and the second surfactant, but also the cleaning agent preparation which contains the two surfactants has a melting point. This is therefore meltable as such. The cleaning agent preparation is therefore a meltable mixture. The cleaning agent preparation differs in this respect from a mixture in which, when heated, an individual component initially melts and separates from the rest of the mixture. The cleaning agent preparation according to the solved problem remains a mixture through the melting process and can be solidified again after melting. In this case, components, in particular the first and the second surfactant, remain mixed with one another. The mixture can then be melted again.

[0010] By using a first and a second surfactant, a particularly high cleaning performance can be achieved, in particular since the

[0011] Cleaning agent preparation is water-soluble. To achieve optimal cleaning effect, the surfactants used in a cleaning agent preparation can be anionic and / or cationic and / or zwitterionic and / or non-ionic.

[0012] The water solubility of the cleaning agent preparation can be characterized by the fact that the

[0013] The cleaning agent dissolves in water upon contact. This does not necessarily result in a solution in the chemical sense. A suspension may also form.

[0014] Preferably, the cleaning agent preparation is water-soluble at least at + 8 ° C. This can be particularly advantageous if the

[0015] The cleaning agent preparation is designed as a detergent preparation. Thus, objects, preferably textiles, can be cleaned at temperatures as low as +8°C.

[0016] The cleaning agent preparation can, in particular, be a washing agent preparation. It can also be another type of cleaning agent preparation, such as a cleaning agent preparation.

[0017] A water-soluble cleaning agent formulation can be used in a variety of ways to clean different objects, particularly textiles. This makes it an improved cleaning agent.

[0018] A cleaning agent according to the invention can be further improved by the use of a first and a second surfactant. A particular selection of the two surfactants can be particularly advantageous if the

[0019] The cleaning agent preparation contains additional cleaning-active substances, as described below and / or claimed and / or known to the person skilled in the art. Thus, an interaction of the surfactants with each other and / or with another cleaning-active substance can particularly improve the cleaning performance of the cleaning agent preparation.

[0020] The first and second surfactants can be particularly advantageous in a process for producing a

[0021] Cleaning agent preparation as described and / or claimed below.

[0022] The use of two surfactants with different melting temperatures can lead to a beneficial reduction in the melting temperature of the cleaning agent preparation. The advantage of lowering the melting temperature is that the cleaning agent preparation can be melted and further processed at lower temperatures. It has surprisingly been shown that lowering the processing temperature of the cleaning agent preparation has a positive effect on the quality of a cleaning agent made from it. For example, a lower processing temperature can prevent the decomposition of substances used in the production of a cleaning agent and which are heated by melting the cleaning agent preparation. This can, for example, lead to additives used in the production of a cleaning agent, such as enzymes or fragrances, being retained.

[0023] Furthermore, the reduction of a processing temperature due to the lower melting temperature in a cleaning agent preparation according to the invention can make the production of a cleaning agent more cost-effective.

[0024] A reduction in the melting temperature of the cleaning agent preparation by 20 °C compared to the melting temperature of the first surfactant can already trigger significant quality improvements. Particularly high-quality cleaning agents can be produced from cleaning agent preparations whose melting temperature is more than 40 °C below the melting temperature of the first surfactant. The first surfactant is preferably the surfactant in the cleaning agent preparation with the highest melting temperature.

[0025] In particular, it can be provided that the reduction in the melting temperature of the cleaning agent preparation caused by the second surfactant is at least 20 ° C, preferably at least 40 ° C.

[0026] It can be provided that further ingredients of the cleaning agent preparation bring about a reduction in the melting temperature of the cleaning agent preparation. For example, as described below, the cleaning agent preparation can contain a third or further surfactants which bring about a reduction in the temperature. Other ingredients such as additives can also bring about a reduction in the melting temperature of the cleaning agent preparation. In an advantageous embodiment, it can be provided that the cleaning agent preparation contains a third surfactant with a melting temperature which is below the melting temperature of the second surfactant. In this way, a cleaning agent preparation can be designed with a particularly high cleaning performance, which can be advantageous, in particular in detergent preparations or washing agents.

[0027] It can also advantageously be provided that more than three surfactants are used in a cleaning agent preparation as mentioned above or as claimed below in order to produce a particularly effective cleaning agent. These additional surfactants have a melting temperature that is preferably at least lower than the melting temperature of the first, preferably the second, surfactant. Thus, the melting temperature of the cleaning agent preparation can be further reduced, thereby significantly improving a process for producing a cleaning agent preparation or a cleaning agent.

[0028] The first surfactant preferably has a melting point of at least 120°C. The second surfactant preferably has a melting point of at most 120°C. The combination of such high-melting and low-melting surfactants can offer particular advantages. For example, there are highly effective high-melting surfactants whose melting point can, however, be problematic for subsequent processing in cleaning agent production. A combination with low-melting surfactants can therefore be advantageous, as already described. Especially with low-melting surfactants, a large number of suitable, purely naturally obtainable surfactants are available. These can be optimally combined with a high-melting surfactant, which can also be synthetically produced. In one advantageous embodiment, it can be provided that the first and / or the second and / or the third surfactant are anionic.Thus, a cleaning agent preparation can be largely biodegradable, creating a particularly environmentally friendly cleaning agent preparation. Preferably, all surfactants in a cleaning agent preparation are anionic, which allows a particularly high proportion of the cleaning agent preparation to be biodegradable.

[0029] In an advantageous embodiment of the cleaning agent preparation according to the invention, it can be provided that the melting temperature of the first surfactant is greater than 160 ° C, in particular greater than 200 ° C. Thus, for example, highly effective synthetic surfactants, for example sodium lauryl sulfate derivatives, can be used in a cleaning agent preparation, whereby cleaning agents with particularly high cleaning performance can be produced.

[0030] Alternatively or additionally, it may be provided that the melting temperature of the second surfactant is a maximum of 100 ° C, in particular a maximum of 80 ° C. Thus, surfactants of plant or animal origin can preferably be used as the second surfactant, which are relatively easy, inexpensive, and resource-poor to extract.

[0031] Alternatively or additionally, it can be provided that the melting temperature of a third surfactant, in particular of the aforementioned third surfactant, is a maximum of 80 ° C, preferably a maximum of 40 ° C.

[0032] In an advantageous embodiment, it can be provided that the melting temperatures of the first and second surfactants differ by more than 50°C. Particularly preferably, the melting temperatures differ by more than 100°C. Such embodiments can, on the one hand, lead to an effective reduction in the melting temperature and, on the other hand, allow a particularly large number of surfactants, such as surfactants of natural origin, to be used.

[0033] In an advantageous embodiment, the melting temperature of the cleaning agent preparation can be in a range between 130°C and 180°C. This allows relatively thermolabile additives to be incorporated into a cleaning agent preparation. Furthermore, processing of the cleaning agent preparation, in particular into powder or granules, can be carried out more quickly, since cooling and hardening of the molten cleaning agent preparation can take less time due to the lower melting temperature.

[0034] In an advantageous embodiment, the cleaning agent preparation can have a surfactant content of between 40 and 70 percent by weight. A surfactant content of 40 to 70 percent by weight can ensure a particularly high cleaning effect.

[0035] Values ​​of weight percentages and weight specifications each indicate a quantity that refers to the dry mass, i.e. to a solid state, of the components.

[0036] Alternatively or additionally, it can be provided that the first surfactant in the cleaning agent preparation has a weight proportion of between 30 and 60 percent by weight. Alternatively or additionally, it can be provided that the second surfactant in the cleaning agent preparation has a weight proportion of between 7.5 and 20 percent by weight. An excess of the first surfactant over the second surfactant can be particularly advantageous if the first surfactant has a particularly high cleaning action, but has a particularly high melting point, for example at least 160 ° C. The second surfactant can then reduce the melting point of the cleaning agent preparation, for example, as described above or claimed below, between 130 ° C and 180 ° C, which is advantageous.

[0037] Preferably, the aforementioned third surfactant in the cleaning agent preparation has a weight fraction of between 15 and 30 percent by weight. This allows the melting point of the cleaning agent preparation to be further reduced, allowing the use of a surfactant with a particularly high melting point.

[0038] In an advantageous embodiment, the first surfactant can be sodium lauryl sulfate or a sodium lauryl sulfate derivative. Sodium lauryl sulfate or sodium lauryl sulfate derivatives are highly effective, fat-dissolving surfactants that are also relatively inexpensive and can thus be advantageously used to produce an improved cleaning agent formulation.

[0039] Sodium lauryl sulfates with a melting point of 206 ° C are preferably used.

[0040] In particular, it can advantageously be provided that the sodium lauryl sulphate derivative is sodium lauryl ether sulphate, which is particularly fat-dissolving and inexpensive.

[0041] In an advantageous embodiment, it can be provided that the second and / or a third surfactant, for example the aforementioned third surfactant, is / are of plant origin. Thus, easily obtainable, readily biodegradable compounds can advantageously be used as the second and / or third surfactant. This also makes it possible to produce a vegan cleaning agent, which can be appealing to customers.

[0042] In particular, it can be provided that the second and / or the third surfactant are obtained from coconut fat and / or palm fat. For example, it can be provided that the second surfactant is sodium cocoyl isothionate or a derivative thereof with a preferred melting point of 75°C. The third surfactant can be sodium cocosulfate or a derivative thereof with a preferred melting point of 40°C. These two surfactants are obtained from coconut fat, so that when using a second and at least one third surfactant, the surfactants can originate from the same basic resource, which can be advantageous from a logistical and process engineering perspective.

[0043] In an advantageous embodiment, it can be provided that the cleaning agent preparation contains at least one polymer. The polymer can have a similar melting temperature to that of a surfactant, in particular to that of the first surfactant. An advantage of polymers can be that they can be used, for example, as coloring agents, thickeners or opacifiers, whereby a cleaning agent can be improved. Polymers can particularly advantageously serve as dispersing aids to improve the removal of dirt particles and thus prevent dirt particles from redepositing during a cleaning or washing process.

[0044] Polymers are preferably intended to be biodegradable so that they do not accumulate in the environment. In preferred applications, the cleaning agent preparation may contain a weight fraction of polymers of 1 to 10, in particular 1.5 to 5, percent by weight.

[0045] In particular, polyvinyl alcohol can be used as the polymer. Polyvinyl alcohols are water-soluble and easy to separate and dispose of from dispersion-containing wastewater. This makes polyvinyl alcohols particularly suitable for use in cleaning agent preparations, particularly in detergent preparations. Furthermore, polyvinyl alcohols have a melting point in the range of 195°C to 245°C. Their resistance to oils, fats, and organic solvents also makes them particularly well-suited as a component of a cleaning agent preparation.

[0046] Alternatively or additionally, acrylic polymers or other polymers known to the person skilled in the art may also be used.

[0047] It can also be particularly advantageous for the polymer to be a soil-release polymer. These are water-soluble, water-dispersing polycondensates based on dicarboxylic acids, diols, or cellulose ethers. This can prevent the graying of textiles, especially when anionic surfactants are included in the cleaning agent formulation. This can significantly improve cleaning agents.

[0048] In an advantageous embodiment, the cleaning agent preparation can contain at least one temperature-stable, non-melting bleaching agent. Oxygen- or chlorine-forming compounds, especially per compounds (i.e., molecules with an oxygen-oxygen bond) such as sodium percarbonate, can be used as bleaching agents. An advantage of bleaching agents can be that, in addition to their bleaching effect for removing stubborn stains, they can also have antibacterial effects.

[0049] Preferably, it can be provided that the bleaching agent(s) in the cleaning agent preparation have a weight proportion of 3 to 15 weight percent.

[0050] Alternatively or additionally, the cleaning agent preparation may contain at least one complexing agent. This can reduce water hardness. Furthermore, complexing agents can stabilize bleaching agents and improve the cleaning power of surfactants. In particular, citrate compounds, polyacrylic sodium salts, and polyethylene glycol can be used as complexing agents.

[0051] Alternatively or additionally, the cleaning agent preparation may contain framework-forming agents, preferably silicates, particularly preferably zeolite, for advantageous water softening. The framework-forming agent(s) may preferably have a weight fraction of between 2 and 25 percent by weight in the cleaning agent preparation.

[0052] Alternatively or additionally, the cleaning agent preparation may contain at least one enzyme. Lipases and / or cellulases are preferably used as enzymes, with a preferred proportion of 0.05 to 2 percent by weight of the cleaning agent preparation. By using enzymes, a cleaning agent preparation can be tailored to the specific application.

[0053] Less thermostable enzymes can now advantageously be used in a cleaning agent preparation, since a melting temperature of a cleaning agent preparation can be lowered, as described above, whereby the cleaning agent preparation can be further processed at a further processing temperature which, in particular, does not have a denaturing effect on the less thermostable enzymes.

[0054] Alternatively or additionally, the cleaning agent preparation may contain at least one fragrance. Essential oils, in particular, may be used. Thus, a cleaning agent preparation can have a pleasant fragrance, which can be particularly user-friendly.

[0055] In an advantageous embodiment, the cleaning agent preparation can be in a solid phase at room temperature, particularly in the form of granules or monolithic. Thus, the cleaning agent preparation can be easily stored and / or subsequently processed into a cleaning agent.

[0056] In a further advantageous embodiment, it can be provided that the cleaning agent preparation is water-free. This can ensure that the

[0057] The cleaning agent preparation retains its desired consistency when heated. If it contains water, heating, particularly above 100 °C, would cause water to escape from the cleaning agent preparation in the form of steam. This could then swell, which would impair further processing, for example, by applying it to a nonwoven fabric in the form of a melt film.

[0058] To achieve the above-mentioned object, the features of the independent claim directed to a water-soluble cleaning agent are provided according to the invention.

[0059] In particular, to achieve the stated object, it is proposed for a water-soluble cleaning agent to have an inner layer and an outer fleece, wherein a meltable cleaning agent preparation is applied to the inner layer between a first side of the inner layer and the outer fleece, and wherein it is further provided that the outer fleece, the inner layer and the cleaning agent preparation are water-soluble. The cleaning agent preparation is preferably designed as described above. The cleaning agent preparation is particularly preferably designed according to one of the claims directed thereto. As a result, the cleaning agent can be activated in contact with water, so that the cleaning agent preparation, in particular the aforementioned surfactants, become cleaning-active.Another advantage of such a water-soluble cleaning agent can be that it can be disposed of particularly easily and in an environmentally friendly manner. The advantage of a cleaning agent applied to an inner layer is that the cleaning agent can be protected from external influences. Likewise, a user can be protected from, for example, skin-irritating components of the cleaning agent. The cleaning agent is preferably a detergent or a cleaning agent.

[0060] The cleaning agent can preferably be designed as described below:

[0061] A) Cleaning agent as previously described.

[0062] B) Cleaning agent as described above, characterized in that a second side of the inner layer is covered by a second water-soluble outer fleece, in particular wherein the cleaning agent preparation is also applied to the second side of the inner layer. This advantageously allows more cleaning agent preparation to be applied to the same surface area of ​​an outer fleece. It can also be advantageous that a second outer fleece can provide even greater protection for the cleaning agent preparation and the user.

[0063] It can also be provided that the cleaning agent has more than one inner fleece and / or that at least two layers of the cleaning agent preparation or the like are applied in such a way that the cleaning agent preparations can advantageously be dissolved and activated in the added water within different exposure times and / or at different temperatures.

[0064] C) Cleaning agent with the features as described under A) or B), characterized in that the inner layer has at least one water-soluble inner fleece which carries the detergent preparation. In this way, a cleaning agent can be advantageously produced, in particular when the cleaning agent preparation, as described above or claimed below, is in a solid phase and is combined by sprinkling onto the inner fleece and subsequent melting. The inner fleece carrying the cleaning agent can then advantageously be pressed with two outer fleeces.

[0065] D) Cleaning agent with the features as described under A), B) or C), characterized in that the outer nonwovens and / or the at least one inner nonwoven consist of water-soluble fiber polymers such as, for example, polyvinyl alcohol and / or alginates and / or polyacrylic acid and / or cellulose. The acceptance and handling of the cleaning agent is significantly improved if at least the outer nonwovens made of fiber-containing material have a paper-like feel.

[0066] E) Cleaning agent with the features as described under A), B), C) or D), characterized in that a melting temperature of the outer fleece and / or of the at least one inner fleece is higher, in particular at least 30°C higher, than the melting temperature of a surfactant mixture of the cleaning agent preparation as described above or claimed below. As a result, a process for producing a cleaning agent can be particularly gentle on the cleaning agent preparation and economical.

[0067] F) A cleaning agent having the features as described in any one of sections A) to E), characterized in that the meltable cleaning agent preparation can be applied to the at least one inner layer of the cleaning agent, preferably by scattering or powder application, slot die coating, or gravure roller application. Thus, a manufacturing process can be carried out using preferably known manufacturing techniques, so that a cleaning agent preparation according to the invention can be processed particularly economically into a cleaning agent, whereby a selling price of the cleaning agent can be particularly customer-friendly.

[0068] G) Cleaning agent with the features as described under one of the sections A) to F), characterized in that an application quantity of the meltable cleaning agent preparation as claimed above or below is preferably between 400 g / m 2 and 1200 g / m 2This means that the amount of cleaning agent applied can be optimally adapted to the final cleaning agent.

[0069] The cleaning agent can preferably be designed to be portionable, allowing a user to advantageously carry out a cleaning process with a precise dosage of the cleaning agent preparation. For example, when washing textiles, it may be advantageous to use 10g to 80g of the detergent preparation.

[0070] To achieve the stated object, the features of the independent claim directed to a method for producing a cleaning agent preparation as described above or claimed below are provided according to the invention. In particular, to achieve the stated object, in such a method it is proposed according to the invention that ingredients of the cleaning agent preparation are mixed with one another in a mixing container at a temperature which is above a melting temperature of the cleaning agent preparation, in particular above a melting temperature of the first surfactant, and that the molten mixture is cooled to a solid after mixing. The first surfactant is preferably added to the mixing container first. In this way, a cleaning agent preparation with the desired properties can be produced.

[0071] In particular, after solidification and / or crystallization, a mass, especially a monolithic mass that forms, can be granulated. In this case, it can advantageously be provided that the cleaning agent preparation is processed by a grinding and homogenization process into a scatterable and free-flowing powder. Thus, the cleaning agent preparation produced according to the invention can be optimally stored and uniformly processed in the cleaning agent, preferably as described above, which is advantageous.

[0072] Alternatively or additionally, the features of the independent claim directed to a method for producing a water-soluble cleaning agent are provided according to the invention to achieve the stated object. In particular, it is proposed to achieve the stated object in such a method that the cleaning agent is designed according to the invention, in particular as described above and / or as claimed below, and that the cleaning agent preparation is applied to the inner layer and then covered by the outer fleece and that then the inner layer, the outer layer and the intermediate

[0073] Cleaning agent preparation are pressed together.

[0074] This advantageously allows a water-soluble cleaning agent to be produced, in particular with a cleaning agent preparation according to the invention. By compressing the inner layer, the outer layer, and the intermediate cleaning agent preparation, the cleaning agent can be brought into a stable, user-friendly form. The compression is all the more effective if, as described and claimed below, the inner layer and / or the outer layer are bonded to the cleaning agent preparation to form a solid composite.

[0075] Pressing can be carried out in particular by calendering or other methods known to the person skilled in the art.

[0076] In a further development of the method for producing a cleaning agent, it can be provided that before the cleaning agent preparation is applied to the inner layer, at least one further substance is applied to the inner layer, in particular wherein the at least one further substance preferably contains a temperature-stable, non-melting bleaching agent and / or a complexing agent and / or a framework former and / or an enzyme and / or a fragrance. Thus, a cleaning agent, in particular as described above, can be provided with a further substance, preferably with a temperature-stable, non-melting bleaching agent as mentioned above and / or a complexing agent and / or a framework former and / or an enzyme and / or a fragrance. From these groups of substances just mentioned, thermolabile compounds can particularly preferably be used alternatively or additionally.

[0077] The cleaning agent preparation can preferably be applied to the inner layer as a melt film or as granules.

[0078] A granulate comprises grains of different sizes and includes, in addition to coarser grains, particularly powdery grains.

[0079] For example, granules can be sprinkled on.

[0080] The application of a melt film can be carried out, for example, by heating and extruding from an extrusion device.

[0081] In a further development of the method for producing a cleaning agent, it can be provided that, for application, the cleaning agent preparation is melted at a temperature below the melting temperature of the first surfactant and then applied to the inner fleece as a melt film. Thus, the cleaning agent preparation can advantageously be processed and applied at a relatively low temperature, thereby preventing decomposition or damage to components of the cleaning agent during production of the cleaning agent.

[0082] Alternatively or additionally, it can advantageously be provided that the cleaning agent preparation is applied to the inner layer as granules and then melted below the melting temperature of the first surfactant. It can advantageously be provided that the cleaning agent preparation and the inner layer, with which the cleaning agent preparation can be fused to form a composite, consist of the same polymer, preferably a polyvinyl alcohol.

[0083] In a further development of the method for producing a cleaning agent, it can be provided that the inner layer and the cleaning agent preparation are bonded to form a solid composite, in particular at a temperature in the range between 120 ° C and 240 ° C. Thus, in particular at low melting temperatures in the range of 150 ° C to 180 ° C, a solid composite of the inner layer and the cleaning agent preparation can be produced particularly gently, so that at least thermolabile compounds, in particular the aforementioned thermolabile compounds, can be used in a cleaning agent.

[0084] A method for producing a cleaning agent comprising a cleaning agent preparation according to the invention will now be described in more detail using an exemplary embodiment, but is not limited to this exemplary embodiment. Further exemplary embodiments arise from combining the features of one or more claims or previously described variants of the invention with one another and / or with one or more features of the exemplary embodiment.

[0085] It shows :

[0086] Fig. 1 shows a process for producing a cleaning agent as described above, comprising a cleaning agent preparation according to the invention. In the production of a cleaning agent 1 as described above, as shown in Figure 1, a cleaning agent preparation 3 according to the invention is processed which contains a first, a second and a third surfactant 16, 17, 18 and a polymer 19, in particular polyvinyl alcohol (Figure 1 A, F). Other additives, such as a temperature-stable, non-melting bleaching agent and / or a complexing agent and / or a framework former and / or an enzyme and / or a fragrance 10 can be contained in the cleaning agent preparation 3 in order to be able to produce an optimal cleaning agent 1 with the advantages described above in a customer-friendly manner. Thermolabile and / or less temperature-stable compounds can also be used as additives.

[0087] The cleaning agent preparation 3 is designed as a washing agent preparation. As can be seen in Fig. II and Fig. 1J, the cleaning agent preparation is processed into a cleaning agent 1 designed as a washing agent that can be portioned via cutting edges 13.

[0088] The cleaning agent 1 is particularly active in cleaning because sodium lauryl sulfate or a sodium lauryl sulfate derivative is used as the first surfactant 16. By using the second surfactant 17, in particular sodium cocoyl isothionate or a derivative thereof, and the third surfactant 18, in particular sodium cocosulfate or a derivative thereof, the melting temperature of the cleaning agent preparation 3 is brought at least 20°C below the melting temperature of the sodium lauryl sulfate during the production of the cleaning agent preparation 3, so that the process for producing the cleaning agent preparation 3 is particularly gentle and advantageous.

[0089] The cleaning agent 1 of the embodiment is particularly environmentally friendly, since the second and third surfactants 17, 18 are each of plant origin and together represent between 40 and 70 percent by weight of the

[0090] Cleaning agent preparation 3. Furthermore, cleaning agent 1 is water-soluble and largely biodegradable.

[0091] The process of the embodiment shown in Figure 1 is as follows:

[0092] The cleaning agent preparation 3, which is present as granules 14 at room temperature, is applied evenly to a first side 6 of an inner fleece 5 forming an inner layer 4 (Figure 1A). To apply the cleaning agent preparation 3, it is melted at a temperature below the melting temperature of the first surfactant 16 and thus distributed evenly over the inner layer 4 (Figure 1B). The cleaning agent preparation 3 applied to the inner layer 4 is then covered by an outer fleece 7 (Figure 1C). In a subsequent step, the inner layer 4, the outer fleece 7 and the cleaning agent preparation 3 located therebetween are pressed together (Figure 1D).

[0093] The composite is then rotated. A fragrance 10 is then applied, for example, by spraying (Figure 1E) to the second side 9 of the inner layer 4 before applying the cleaning agent preparation 3 (Figure 1F). Depending on the user's wishes, the cleaning agent preparation 3 of Figure 1F can be configured differently from the cleaning agent preparation 3 of Figure 1A in order to produce a cleaning agent 1 suitable for the application.

[0094] In a subsequent step, in order to apply the cleaning agent preparation 3, it is melted at a temperature below the melting temperature of the first surfactant 16 and thus evenly distributed together with the fragrance 10 on the second side 9 of the inner layer 4 (Figure 1G). The cleaning agent preparation 3 applied to the inner layer 4 is then covered by a second outer fleece 11 (Figure 1H). In a subsequent step, the inner layer 4, the outer fleece 11 and the preparation 3, 10 located therebetween are pressed together (Figure 1I) and cooled to form a finished cleaning agent 1.

[0095] The final cleaning agent 1 can be portioned by embossed cut edges, which is particularly user-friendly. Furthermore, the cleaning agent 1 (Figure II, J) is particularly easy to handle, since the cleaning agent preparations 3 are protected from external influences by the outer fleeces 7, 11, and the user does not come into contact with skin-irritating compounds of the cleaning agent preparations 3.

[0096] The invention generally proposes a cleaning agent preparation 3, such as in particular a washing agent preparation, which is water-soluble and which contains at least a first and a second surfactant 16, 17, wherein the second surfactant 17 has a lower melting point than the first surfactant 16 and wherein the melting point of the cleaning agent preparation 3 is at least 20°C, preferably at least 40°C, below the melting point of the first surfactant 16.
