Description

[0001] The invention relates to a shoe detergent and a use of a shoe detergent. In particular, the invention relates to a shoe detergent designed to clean and / or treat a shoe in a washing machine and / or washer-dryer.

[0002] Shoes often get dirty in everyday life. Cleaning shoes is often laborious and time-consuming. Even invisible dirt in the form of sweat and bacteria is often a reason to clean. For quick and superficial cleaning, shoes are often cleaned with household products and other cleaning products such as rags, brushes, wet wipes or sponges, e.g. abrasive ones or similar. Textiles in whose fibers the dirt is absorbed, or the inside of the shoe cannot usually be satisfactorily treated with these conventional methods, as many areas are inaccessible and these methods do not clean effectively enough. A washing machine can also be used to clean shoes. Conventional detergents and special shoe detergents, especially sneaker detergents, contain little to no special components that offer additional benefits for shoe cleaning and care.These detergents do not offer any additional benefit or care for the shoes, but only contribute to the cleaning performance.

[0003] The invention therefore addresses the problem of providing a shoe detergent with improved washing performance.

[0004] According to the invention, this problem is solved by a shoe detergent having the features of patent claim 1 and a use of the shoe detergent having the features of patent claim 9. Advantageous embodiments and further developments of the invention emerge from the following subclaims.

[0005] The advantages achieved with the invention include not only increased washing performance but also an enhanced effect of specific ingredients. It is possible to release specific ingredients at different times during a washing process.

[0006] The invention relates to a shoe detergent which is solid and contains several layers of active substances.

[0007] The invention provides a user of the shoe detergent with an additional benefit and / or advantage for cleaning and caring for shoes in the washing machine and / or dryer. The fact that the shoe detergent is in solid form prevents the active substances of the multiple active substance layers from being dosed simultaneously during the washing process, meaning that not all active substances work simultaneously. This has a positive effect on the washing performance and its effectiveness. A refatting ingredient, for example, reduces the surfactant effect in a washing process and, if acting simultaneously with an ingredient for washing effectiveness, can lead to poorer washing results.

[0008] Even an ingredient for waterproofing or dirt repellency may not work optimally if added during the main wash cycle due to excessive dilution. These disadvantages are prevented by the layered structure of the solid shoe detergent. The multi-layered structure of the solid detergent means that it only dissolves gradually during the wash cycle, allowing the different active ingredient layers to be released at different times and gradually unfold their different effects.

[0009] The shoe detergent preferably contains up to eight, preferably six, and more preferably four active substance layers. Each active substance layer comprises one or more active substances. An active substance can be, for example, a detergent, a refatting substance, an impregnating and / or dirt-repellent active substance, a disinfectant or germ-reducing substance, or an enzyme. Each of the multiple active substance layers preferably comprises a predetermined active substance that is different from the active substances of the other active substance layers.

[0010] In a preferred embodiment, the multiple active substance layers are arranged in a predetermined order depending on their predetermined release time in a washing process and / or their predetermined effect. As a result, the multiple active substance layers are arranged and configured such that they are water-soluble at different times. They preferably have a predetermined order in their arrangement, so that active substance layers dissolve faster or slower in the washing process depending on the size of their exposed layer surface. The active substance layers can be arranged one above the other.

[0011] It is also possible for the active substance layers to be arranged one inside the other, so that one of the active substance layers encloses another active substance layer. As a result, an inner active substance layer is only dissolved in the washing process when it is exposed by dissolving the active substance layer enclosing it. The active substance layers can each individually and / or together have any shape or form, e.g. a cuboid, spherical or elliptical shape. Alternatively or additionally, the multiple active substance layers each have different water solubility. As a result, the different active substance layers are dissolved at different times in the washing process.

[0012] Preferably, the multiple active substance layers each comprise different ingredients that are at least partially immiscible and / or formulable or functionally separable. The targeted use of the active substance layers for ingredients that are partially immiscible / formulable or functionally separable can thus be released at a later time during the washing process by influencing the solubility of the solid detergent.

[0013] In a preferred embodiment, one of the multiple active substance layers contains a detergent. This achieves increased cleaning performance.

[0014] Preferably, one of the multiple active substance layers comprises a refatting ingredient. The use of a refatting ingredient in the washing process can contribute to the softness of a shoe's leather surface and prevent drying and the formation of cracks. The use of one or more refatting ingredients in the shoe detergent is intended to care for the leather of the shoes. Preferably, the refatting ingredient is arranged in a different active substance layer than the detergent.

[0015] In a preferred embodiment, one of the multiple active substance layers comprises a waterproofing and / or dirt-repellent ingredient. The use of the waterproofing / dirt-repellent ingredient can result in the washed shoes staying clean longer. Preferably, the waterproofing and / or dirt-repellent ingredient is arranged in a different active substance layer than the detergent and the moisturizing ingredient.

[0016] Preferably, one of the multiple active substance layers contains an enzyme. The enzyme is preferably phosphodiesterase. Phosphodiesterase is an enzyme suitable for breaking down body dirt and body odors. It reduces odors in the shoe and can also have an antimicrobial effect. Multiple enzymes can also be used, possibly at different times, to improve cleaning performance. The enzyme is preferably arranged in a different active substance layer than the detergent substance, the waterproofing and / or dirt-repellent ingredient, and the moisturizing ingredient.

[0017] In a preferred embodiment, the enzyme-containing active substance layer is arranged and / or configured in the multiple active substance layers in such a way that it is soluble in water at a time lag relative to the active substance layer containing the detergent. The enzyme is therefore released during the washing process at a time lag relative to the detergent substance.

[0018] Furthermore, the invention relates to the use of a shoe detergent according to one or more of the embodiments described above for washing shoes in a washing machine and / or dryer.

[0019] An embodiment of the invention is shown schematically in the drawings and is described in more detail below. It shows schematically and not to scale Fig. 1 is a cross-sectional view of a shoe detergent according to a first embodiment; Fig. 2 a cross-sectional view of a shoe detergent according to a second embodiment; and Fig. 3 a cross-sectional view of a shoe detergent according to a third embodiment.

[0020] Fig. 1 shows a cross-sectional view of a shoe detergent according to a first embodiment. The shoe detergent is solid and contains several—purely by way of example, four—active substance layers 1, 2, 3, 4. The several active substance layers 1, 2, 3, 4 are arranged and configured such that they are water-soluble at different times and / or each have a different water solubility. They are arranged one above the other and each and together form a cuboid. The several active substance layers 1, 2, 3, 4 have different ingredients that are at least partially immiscible and / or formulable or functionally separable.

[0021] One of the multiple active substance layers 1, 2, 3, 4 contains a detergent. Another of the multiple active substance layers 1, 2, 3, 4 contains a moisturizing ingredient. Another of the multiple active substance layers 1, 2, 3, 4 contains an impregnating and / or dirt-repellent ingredient. Another of the multiple active substance layers 1, 2, 3, 4 contains an enzyme such as phosphodiesterase. As a result, each of the active substance layers 1, 2, 3, 4 contains a different active substance.

[0022] Fig. Figure 2 shows a cross-sectional view of a shoe detergent according to a second embodiment. Fig. 2 shoe detergent corresponds to the one in Fig. 1, with the difference that the active substance layers 1, 2, 3, 4 are not arranged one above the other, but rather that the active substance layer 1 is surrounded by the active substance layer 2, the active substance layer 2 by the active substance layer 3, and the active substance layer 3 by the active substance layer 4. The active substance layers 1, 2, 3, 4 are arranged one inside the other.

[0023] Fig. 3 shows a cross-sectional view of a shoe detergent according to a third embodiment. Fig. 3 shoe detergent corresponds to the one in Fig. 2 with the difference that it has a spherical shape. List of reference symbols 1, 2, 3, 4 each active substance layer
