Description

[0001] The subject of the present application is a method for dyeing keratin materials, in particular human hair, which comprises applying at least two different agents (a) and (b). The agent (a) represents a concentrate comprising at least one amino-functional silicone polymer (a1). The agent (b) is a carrier formulation comprising water (b1) and at least one fatty component (b2) and at least one coloring compound (b3). Prior to application, an application mixture is prepared by mixing the agents (a) and (b), applied to the keratin material, allowed to act and washed off again.

[0002] A second subject of the present application is a multi-component packaging unit (kit) for coloring keratin materials, in particular human hair, comprising the agents (a) and (b) respectively packaged in two different containers.

[0003] Changing the shape and color of keratin materials, especially human hair, is an important area of ​​modern cosmetics. To change the color of hair, experts are familiar with various coloring systems depending on the coloring requirements. Oxidation dyes are generally used for long-lasting, strong coloring with good fastness properties and good gray coverage. Such colorants contain oxidation dye precursors, so-called developer components, and coupler components, which form the actual dye with each other under the action of an oxidizing agent, such as hydrogen peroxide. Oxidation dyes are characterized by very long-lasting coloring results.

[0004] When direct dyes are used, the ready-made dye diffuses from the colorant into the hair fiber. The dyeings obtained with direct dyes have a shorter shelf life and faster washability than oxidative hair dyeing. Dyeings with direct dyes usually remain on the hair for a time of 5 to 20 washes.

[0005] It is known to use color pigments to produce short-term color changes on hair and / or skin. Color pigments are usually understood to be insoluble coloring substances. These substances are present in the form of small particles in the dye formulation without dissolution and are only deposited on the hair fiber and / or skin surface from the outside. Therefore, they can usually be removed again without residue by washing several times with a detergent containing a surfactant. Various products of this type are available on the market under the name hair dye cream (hair mascara).

[0006] The advantage of cream hair dye products is that the colorant compounds, such as pigments, are deposited only in the form of a film on the surface of the keratin fibers. Therefore, the properties of the keratin fibers themselves are not changed during the application of the product, so that the use of cream hair dye products is associated with particularly low hair damage. If the user wishes to restore his original hair color, the dye can be removed from the keratin fibers quickly, completely and without residue without damaging the fibers or changing the original hair color. Therefore, the development of pigment-based keratin colorants is completely in line with the trend.

[0007] However, as before, there is still a need to optimize this coloring system, with durability and leveling being particularly desirable.

[0008] The object of the present invention is to provide a dyeing system having fastness properties comparable to those of oxidation dyeing, if possible. The wash fastness properties should be outstanding, but the oxidation dye precursors usually used for this purpose should be avoided. A technology was sought which would make it possible to fix the colorant compounds known from the prior art, in particular the pigments, on the hair in an extremely durable manner. When these agents are used in the dyeing process, intense dyeing results with good fastness properties should be obtained. A particular emphasis of this task was to achieve a uniform dyeing result, i.e. to dye the keratin fibers very uniformly, regardless of their structure, length and nature.

[0009] Surprisingly, it has now been found that the above-mentioned task can be solved very well if the dyeing of keratin materials, especially hair, is carried out by applying at least two agents (a) and (b) to the keratin materials (hair). Here, the agent (a) comprises at least one amino-functional silicone polymer (a1). The agent (a) is preferably in the form of a concentrate which can be prepared in low-water or anhydrous form and comprises aminosilicone (a1) as the main component. Before use, the agent (a) is mixed with a second agent (b), which, in addition to water (b1), also comprises at least one fatty component (b2) and at least one coloring compound (b3). The application mixture prepared by mixing the agents (a) and (b) is then applied to the keratin material, allowed to act, and then rinsed off again with water.

[0010] A first object of the present invention is a method for coloring keratin materials, in particular human hair, comprising the following steps:

[0011] (1) Providing a pharmaceutical agent (a), wherein the pharmaceutical agent (a) comprises:

[0012] (a1) at least one amino-functional silicone polymer,

[0013] (2) providing a pharmaceutical agent (b), wherein the pharmaceutical agent (b) comprises:

[0014] (b1) Water and

[0015] (b2) at least one fat component and

[0016] (b3) at least one coloring compound,

[0017] (3) preparing an administration mixture by mixing agents (a) and (b),

[0018] (4) applying the application mixture prepared in step (3) to a keratin material,

[0019] (5) allowing the application mixture applied in step (4) to act on a keratin material; and

[0020] (6) Rinse the application mixture with water.

[0021] In the work leading to the present invention, it has been shown that particularly intense, uniform and long-lasting color results can be obtained on keratin materials if the agent (a) is provided in the form of a concentrate as described above, which is mixed with the actual colorant (b) only shortly before use. Surprisingly, the application mixture obtained by mixing the two agents (a) and (b) just before application allows to obtain a more intense, more uniform and more long-lasting color result than an otherwise identical formulation comprising all the components of the two agents (a) and (b) from the outset.

[0022] Keratin materials

[0023] Keratin materials include hair, skin, nails (eg fingernails and / or toenails). Wool, fur and feathers also fall within the definition of keratin materials.

[0024] Preferably, keratin materials are understood to be human hair, human skin and human nails, in particular fingernails and toenails. Keratin materials are understood to be human hair.

[0025] Medicine (a)

[0026] In step (1) of the method according to the present invention, a medicament (a) is provided. For example, the medicament (a) can be present in a packaging unit or container and provided to the user in this way. The container can be, for example, a pouch, a bottle, a jar, a jar or another container suitable for cosmetic formulations. Since the medicament (a) is preferably a concentrate of aminosilicone (a1), it is particularly preferred to select a container suitable for the concentrate to package the medicament (a).

[0027] The agent (a) is characterized in that it contains the essential ingredient (a1) of the present invention.

[0028] Amino-functional silicone polymer (a1) in the agent (a)

[0029] The agent (a) comprises at least one amino-functional silicone polymer as an essential ingredient (a1) of the present invention. The amino-functional silicone polymer may also be referred to as aminosilicone or amodimethicone.

[0030] Silicone polymers are generally macromolecules having a molecular weight of at least 500 g / mol, preferably at least 1000 g / mol, more preferably at least 2500 g / mol, particularly preferably at least 5000 g / mol, which comprise repeating organic units.

[0031] The maximum molecular weight of the silicone polymer depends on the degree of polymerization (the number of polymerized monomers) and the batch size, and is also determined in part by the polymerization process. For the purposes of the present invention, it is preferred that the maximum molecular weight of the silicone polymer is no greater than 10 7 g / mol, preferably not more than 10 6 g / mol, particularly preferably not more than 10 5 g / mol.

[0032] Silicone polymers contain many Si-O repeating units, and the Si atoms may carry organic groups, such as alkyl or substituted alkyl groups. Alternatively, silicone polymers are therefore also referred to as polydimethylsiloxanes.

[0033] Corresponding to the high molecular weight of the silicone polymers, these are based on more than 10 Si-O repeating units, preferably more than 50 Si-O repeating units, more preferably more than 100 Si-O repeating units, most preferably more than 500 Si-O repeating units.

[0034] An amino-functional silicone polymer is understood to be a functionalized silicone with at least one structural unit having an amino group. Preferably, the amino-functional silicone polymer has a plurality of structural units, each having at least one amino group. Amino groups are understood to mean primary amino groups, secondary amino groups and tertiary amino groups. All of these amino groups can be protonated in an acidic environment and then exist in their cationic form.

[0035] In principle, amino-functional silicone polymers (a1) can achieve good results if they carry at least one primary amino group, at least one secondary amino group and / or at least one tertiary amino group. However, intensive coloring with optimal wash fastness is achieved when amino-functional silicone polymers (a1) containing at least one secondary amino group are used in the agent (a).

[0036] In a very particularly preferred embodiment, the process according to the invention is characterized in that the agent (a) comprises at least one amino-functional silicone polymer (a1) having at least one secondary amino group.

[0037] The one or more secondary amino groups can be located at various positions on the amino-functional silicone polymer. Particularly good effects are found when amino-functional silicone polymers (a1) are used which have at least one, preferably several, structural units of the formula (Si-amino).

[0038]

[0039] In the structural unit of the formula (Si-amino), the abbreviations ALK1 and ALK2 independently represent a linear or branched divalent C 1 -C 20 Alkylene.

[0040] In a further very particularly preferred embodiment, the process according to the invention is characterized in that the agent (a) comprises at least one amino-functional silicone polymer (a1) which comprises at least one structural unit of the formula (Si-amino),

[0041]

[0042] in

[0043] ALK1 and ALK2 independently express linear or branched C 1 -C 20 A divalent alkylene group.

[0044] Positions marked with an asterisk (*) represent bonding points to other structural units of the silicone polymer. For example, the silicon atom adjacent to the asterisk may be bonded to another oxygen atom, and the oxygen atom adjacent to the asterisk may be bonded to another silicon atom or even to a C 1 -C 6 alkyl.

[0045] Bivalent C 1 -C 20 Alkylene can also be referred to as divalent or divalent C 1 -C 20 Alkylene, which means that each ALK1 or ALK2 group can form two bonds.

[0046] In the case of ALK1, one bond is from the silicon atom to the ALK1 group and the second bond is between ALK1 and the secondary amino group.

[0047] In the case of ALK2, one bond is from the secondary amino group to the ALK2 group and the second bond is between ALK2 and the primary amino group.

[0048] Straight chain divalent C 1 -C 20 Examples of alkylene groups include methylene (—CH 2 -), ethylene (-CH 2 -CH 2-), propylene (-CH 2 -CH 2 -CH 2 -) and butylene (-CH 2 -CH 2 -CH 2 -CH 2 -). Propylene (-CH 2 -CH 2 -CH 2 -) is particularly preferred. Starting from a chain length of 3 C atoms, the divalent alkylene group can also be branched. 3 -C 20 An example of an alkylene group is (-CH 2 -CH(CH 3 )-) and (-CH 2 -CH(CH 3 )-CH 2 -).

[0049] In a further particularly preferred embodiment, the structural unit of the formula (Si-amino) represents a repeating unit in the amino-functional silicone polymer (a1), so that the silicone polymer comprises a plurality of structural units of the formula (Si-amino).

[0050] Particularly suitable amino-functional silicone polymers (a1) having at least one secondary amino group are listed below.

[0051] Dyeings with very optimal wash fastnesses can be obtained if, in the process according to the invention, at least one agent (a) is applied to keratin materials which comprises at least one amino-functional silicone polymer (a1) comprising structural units of the formula (Si-I) and the formula (Si-II):

The individual Si radicals marked with subscripts m and n or p and q do not necessarily have to be present in the form of blocks; rather, the individual units may also be present in a statistically distributed manner, i.e., in formulas (Si-III) and (Si-IV), not every R1-Si(CH 3 ) 2 The groups must be bonded to -[O-Si(CH 3 ) 2 ]-group.

Particularly good dyeing results are obtained when the agent (a) comprises - based on the total weight of the agent (a) - a total amount of 5 to 100% by weight, preferably 25 to 100% by weight, more preferably 50 to 100% by weight, very particularly preferably 75 to 100% by weight of one or more amino-functional silicone polymers (a1).

[0140] In this embodiment, either substantially the aminosilicone (a1) is used, or a small amount of a solubilizer, diluent or carrier is added to the one or more aminosilicones (a1).

[0141] In a further particularly preferred embodiment, the process according to the invention is characterized in that the agent (a) comprises - based on the total weight of the agent (a) - a total amount of 5 to 100% by weight, preferably 25 to 100% by weight, more preferably 50 to 100% by weight, very particularly preferably 75 to 100% by weight of one or more amino-functional silicone polymers (a1).

[0142] Solvent in the drug (a)

[0143] For example, the solvent can be used as a suitable solubilizer or diluent in the medicament (a). Therefore, the medicament (a) according to the present invention may further comprise at least one solvent as an optionally present component.

[0144] Suitable solvents may include, for example, solvents selected from the group consisting of 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2-butylene glycol, dipropylene glycol, ethanol, isopropyl alcohol, diethylene glycol monoethyl ether, glycerol, phenoxyethanol, and benzyl alcohol. 1,2-propylene glycol is particularly preferably used.

[0145] In a further very particularly preferred embodiment, the method according to the invention is characterized in that the agent (a) comprises at least one solvent selected from the group consisting of 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2-butylene glycol, dipropylene glycol, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerol, phenoxyethanol and benzyl alcohol, very preferably 1,2-propylene glycol.

[0146] 1,2-Propanediol is also known as 1,2-propanediol (1,2-propanediol) and has CAS numbers 57-55-6 [(RS)-1,2-dihydroxypropane], 4254-14-2 [(R)-1,2-dihydroxypropane], and 4254-15-3 [(S)-1,2-dihydroxypropane]. Ethylene glycol is also known as 1,2-ethanediol and has CAS number 107-21-1. Glycerin is also known as 1,2,3-propanetriol and has CAS number 56-81-5. Phenoxyethanol has CAS number 122-99-6.

[0147] All solvents previously described are commercially available from various chemical suppliers such as Aldrich or Fluka.

[0148] In another preferred embodiment, the process according to the invention is characterized in that the agent (a) contains - based on the total weight of the agent (a) - one or more solvents in a total amount of 1.0 to 80.0% by weight, preferably 2.0 to 50.0% by weight, more preferably 3.0 to 30.0% by weight and very particularly preferably 4.0 to 20.0% by weight.

[0149] In a further very particularly preferred embodiment, the process according to the invention is characterized in that agent (a) comprises—based on the total weight of agent (a)—1.0 to 95.0% by weight, preferably 2.0 to 15.0% by weight, more preferably 3.0 to 15.0% by weight, very particularly preferably 4.0 to 10.0% by weight of 1,2-propylene glycol.

[0150] Packaging of medicine (a)

[0151] As described above, the agent (a) is a concentrate preferably comprising the ingredient (a1) essential to the present invention as a main component.

[0152] The work carried out in the present invention led to the following suggestion: The pigments used in the dyeing process and the amino-functional silicone polymers (a1) can interact with each other. This interaction seems to occur mainly in an aqueous environment or an environment containing water. One hypothesis is that an interaction occurs between the corresponding surface of the pigment and the amino groups of the silicone polymer, whereby the water may act as a proton donor or proton acceptor.

[0153] This assumption is supported by the observation that in formulations containing, in addition to aminosilicone (a1) and pigment, higher concentrations of the components of the carrier formulation, namely water (b1) and the fatty component (b2), a deposition of resinous material can be observed after a few days. When the formulation was used for dyeing tests after a few days of storage, only dyeings with very low color intensity were obtained. Based on this observation, it was found that the formulation of aminosilicone (a1) in a low-water or anhydrous environment is particularly preferred.

[0154] In a further specifically very particularly preferred embodiment, the process according to the invention is characterized in that agent (a) contains—based on the total weight of agent (a)—less than 10.0% by weight, preferably less than 5.0% by weight, further preferably less than 2.5% by weight, very particularly preferably less than 1.0% by weight of water.

[0155] In other words, in a further specifically very particularly preferred embodiment, the process according to the invention is characterized in that the agent (a) has a water content of 0 to 10.0% by weight, preferably 0 to 5.0% by weight, more preferably 0 to 2.5% by weight, very particularly preferably 0 to 1.0% by weight, based on the total weight of the agent (a).

[0156] Further work has now shown that, above all, the uniformity of the color result also depends on the medicament into which the coloring compound (i.e., the pigment) is incorporated. If the pigment is stored together with the aminosilicone (a1) in the form of a premix and mixed with the cosmetic carrier formulation only shortly before application, the color intensity and wash fastness are significantly improved. However, it has been shown that this type of packaging also has some disadvantages. If the mixture of aminosilicone (a1) and pigment is stored for a longer period of time, a reaction between the two components appears to occur due to the storage time. In low-water or anhydrous Miliau, this reaction is slowed down, but becomes significant from a storage time of several weeks. Therefore, very poor miscibility of the aminosilicone / pigment mixture with the carrier material was observed during the coloring of the properly stored medicament. As a result, very uneven color results were also obtained.

[0157] For this reason, it is further found to be particularly preferred that the medicament (a) itself does not contain any pigments or that these are only used in very small amounts in the medicament (a). For example, very small amounts of pigments may be incorporated into the medicament (a) to color it or give it a more aesthetic appearance.

[0158] In a further specifically very particularly preferred embodiment, the process according to the invention is characterized in that agent (a) comprises—based on the total weight of agent (a)—one or more pigments in a total content of less than 0.1% by weight, preferably less than 0.05% by weight, very preferably less than 0.01% by weight.

[0159] In other words, in a further specifically very particularly preferred embodiment, the process according to the invention is characterized in that the agent (a) has a pigment content of 0 to 0.1% by weight, preferably 0 to 0.05% by weight, very particularly preferably 0 to 0.01% by weight, based on the total weight of the agent (a).

[0160] It is obviously very preferred that the agent (a) does not contain any pigments.

[0161] Pharmacy (b)

[0162] In step (2) of the method according to the invention, the agent (b) is provided. For example, the agent (b) may be present in a packaging unit or container and provided to the user in this manner. The container may be, for example, a pouch, a bottle, a jar, a jar or another container suitable for a cosmetic formulation.

[0163] Agent (b) represents the actual coloring agent and is characterized in that it comprises water (b1) and one or more fatty components (b2) and at least one coloring compound (b3).

[0164] When mixing the agents (a) and (b), the preferably highly concentrated and low-water concentrate (a) is mixed with the actual colorant (b). During this mixing, the aminosilicone (a1) comes into contact with the pigment (b3) incorporated into the emulsion, so that the above-mentioned interaction of the aminosilicone (a1) and the pigment (b3) starts only from this moment of mixing. Surprisingly, it was observed that this type of treatment during the dyeing process produces intense and wash-resistant color results, but is also characterized by particularly good homogeneity.

[0165] Water content (b1) in the agent (b)

[0166] In contrast to agent (a), agent (b) preferably contains a high water content. Particularly suitable for use in the process according to the invention have been found to be those agents (b) which contain - based on the total weight of agent (b) - 50.0 to 98.0 wt.-%, preferably 60.0 to 90.0 wt.-%, more preferably 70.0 to 90.0 wt.-%, most preferably 75.0 to 90.0 wt.-% of water (b1).

[0167] In a further, very particularly preferred embodiment, the process according to the invention is characterized in that the agent (b) contains—based on the total weight of the agent (b)—50.0 to 98.0% by weight, preferably 60.0 to 90.0% by weight, further preferably 70.0 to 90.0% by weight, very particularly preferably 75.0 to 90.0% by weight of water (b1).

[0168] Fatty component (b2) in the agent (b)

[0169] Another feature of the agent (b) is that it comprises at least one fatty component (b2). It has been found that the use of at least one fatty component results in the agent (b) being in the form of an emulsion, which allows particularly good and rapid mixing with the agent (a).

[0170] Fat components are hydrophobic substances that can form emulsions in the presence of water, thereby forming a micellar system.

[0171] For the purposes of the present invention, "fat component" means an organic compound whose solubility in water at room temperature (22° C.) and atmospheric pressure (760 mmHg) is less than 1% by weight, preferably less than 0.1% by weight. The definition of fat component explicitly covers only uncharged (i.e. nonionic) compounds. Fat components have at least one saturated or unsaturated alkyl group with at least 12 C atoms. The molecular weight of the fat component is a maximum of 5000 g / mol, preferably a maximum of 2500 g / mol, particularly preferably a maximum of 1000 g / mol. Fat components are neither polyoxyalkylated compounds nor polyglycerolated compounds.

For the purposes of the present invention, only nonionic substances are explicitly considered as fat components. Charged compounds such as fatty acids and their salts are not considered as fat components.

[0178] Preferred representatives of branched fatty alcohols are 2-octyl-dodecanol, 2-hexyl-dodecanol and / or 2-butyl-dodecanol.

[0179] By selecting a particularly suitable fat component, the polarity and viscosity of the agent (b) can be optimally adjusted, so that when the agents (a) and (b) are mixed, a thorough and rapid mixing is ensured. Due to the high homogeneity of the application mixture prepared from (a) and (b), a particularly uniform color result can also be ensured.

[0180] In this regard, it has been found that the use of at least one C in agent (b) 12 -C 30 Fatty alcohols (b2) produce the best emulsion systems.

[0226] Very preferably, the medicament comprises at least one selected from C12 -C 30 The fatty component (b2) is a fatty alcohol and at least one other fatty component selected from hydrocarbons.

[0227] Coloring compound (b3) in the agent (b)

[0228] The agent (b) used in the method according to the invention comprises at least one coloring compound (b3) as a third component essential to the invention.

[0229] For the purposes of the present invention, a coloring compound is a substance which is able to impart coloration to keratin materials. Particularly suitable coloring compounds may be selected from pigments, direct-action dyes, photochromic dyes and thermochromic dyes.

[0230] In another preferred embodiment, the process according to the invention is characterized in that the agent (b) comprises at least one coloring compound (b3) selected from the group consisting of pigments, direct dyes, photochromic dyes and thermochromic dyes.

[0231] Pigments within the meaning of the present invention are coloring compounds whose solubility in water at 25° C. is less than 0.5 g / L, preferably less than 0.1 g / L, and even more preferably less than 0.05 g / L. The water solubility can be determined, for example, by the method described below: 0.5 g of pigment is weighed into a beaker. A stir bar is added. One liter of distilled water is then added. While stirring on a magnetic stirrer, the mixture is heated to 25° C. for one hour. If insoluble components of the pigment are still visible in the mixture after this time, the solubility of the pigment is less than 0.5 g / L. If the pigment-water mixture cannot be visually assessed due to the high strength of the possibly finely dispersed pigment, the mixture is filtered. If a portion of the undissolved pigment remains on the filter paper, the solubility of the pigment is less than 0.5 g / L.

[0232] Suitable colour pigments may be of inorganic and / or organic origin.

[0233] In a preferred embodiment, the medicament (b) according to the invention is characterized in that it comprises at least one coloring compound (b3) selected from the group consisting of inorganic and / or organic pigments.

[0234] Preferred colored pigments are selected from synthetic or natural inorganic pigments. Inorganic colored pigments of natural origin can be produced, for example, from chalk, ochre, umber, smectite, burnt yellow earth (burnt Terra di Siena) or graphite. In addition, black pigments such as black iron oxide, coloring pigments such as ultramarine or red iron oxide, and fluorescent or phosphorescent pigments can be used as inorganic colored pigments.

[0235] Particularly suitable are colored metal oxides, hydroxides and oxide hydrates, mixed phase pigments, sulfur-containing silicates, silicates, metal sulfides, complex metal cyanides, metal sulfates, chromates and / or molybdates. Preferred colored pigments are black iron oxide (CI 77499), yellow iron oxide (CI 77492), red and brown iron oxides (CI 77491), manganese violet (CI 77742), ultramarine (sodium aluminum sulfosilicate, CI 77007, pigment blue 29), chromium oxide hydrate (CI 77289), iron blue (ferric ferrocyanide, CI 77510) and / or cochineal (carmine).

[0236] According to the invention, colored pearlescent pigments are also particularly preferred colored pigments. These are usually mica and / or mica-based and may be coated with one or more metal oxides. Micas belong to the group of phyllosilicates. The most important representatives of these silicates are muscovite, phlogopite, paragonite, biotite, lepidolite and pearlite. In order to produce pearlescent pigments in combination with metal oxides, the mica, primarily muscovite or phlogopite, is coated with the metal oxide.

[0237] As an alternative to natural mica, synthetic mica coated with one or more metal oxides can also be used as pearlescent pigments. Particularly preferred pearlescent pigments are based on natural or synthetic mica (mica) and are coated with one or more of the above-mentioned metal oxides. The color of the corresponding pigment can be varied by varying the layer thickness of the metal oxide.

[0238] In another preferred embodiment, the method according to the invention is characterized in that the agent (b) contains at least one coloring compound (b3) selected from inorganic pigments, preferably selected from colored metal oxides, metal hydroxides, metal oxide hydrates, silicates, metal sulfides, complex metal cyanides, metal sulfates, bronze pigments and / or from mica- or mica-based-colored pigments coated with at least one metal oxide and / or metal oxychloride.

[0283] In another particularly preferred embodiment, the method according to the invention is characterized in that the agent (b) comprises at least one coloring compound (b3) selected from the group consisting of organic pigments, preferably selected from the group consisting of carmine, quinacridone, phthalocyanine, sorghum red, blue pigments with color index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI74160, yellow pigments with color index numbers CI 11680, CI 11710, CI 15985, CI 19140, CI 20040, CI 21100, CI 21108, CI 47000, CI 47005, green pigments with color index numbers CI 61565, CI 61570, CI74260, green pigments with color index numbers CI 11725, CI 15510, CI 45370, CI 159 Orange pigment 71105, red pigments with color index numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

[0284] Organic pigments can also be color paints. In the sense of the present invention, the term "color paint" refers to particles comprising an absorbed dye layer, the unit of particles and dye being insoluble under the above conditions. The particles can be, for example, inorganic substrates, which can be aluminum, silicon dioxide, calcium borosilicate, calcium aluminum borosilicate or even aluminum.

[0285] For example, you can use alizarin color varnish.

[0286] The use of pigments in the agent (b) according to the method of the invention is particularly preferred due to their excellent light and temperature resistance. It is also preferred that the pigment used has a certain particle size. Therefore, according to the invention, it is advantageous if the at least one pigment has an average particle size D of 1.0 to 50 μm, preferably 5.0 to 45 μm, preferably 10 to 40 μm, 14 to 30 μm. 50 . Average particle size D 50 For example, dynamic light scattering (DLS) can be used.

[0287] The coloring compound (b3) - a coloring compound selected from pigments - represents the third component of the agent (b) essential to the invention. The pigment is very preferably used in a certain amount range in the agent (b). Particularly good results are obtained when the agent (b) comprises - based on the total weight of the agent (b) - a total amount of 0.05 to 10.0% by weight, preferably 0.1 to 7.0% by weight, more preferably 0.2 to 5.0% by weight, most preferably 0.3 to 3.0% by weight of one or more pigments (b3).

[0288] In a further very particularly preferred embodiment, the agent according to the invention is characterized in that agent (b) comprises - based on the total weight of agent (b) - a total amount of 0.05 to 10.0% by weight, preferably 0.1 to 7.0% by weight, more preferably 0.2 to 5.0% by weight, very particularly preferably 0.3 to 3.0% by weight of one or more pigments (b3).

[0289] The agent (b) used in the method according to the invention may also contain one or more direct dyes as coloring compounds (b3). Direct-acting dyes are dyes which are applied directly to the hair and do not require an oxidation process to form a color. Direct dyes are usually nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones, triarylmethane dyes or indophenols.

[0290] Direct dyes within the meaning of the present invention have a water solubility at 25° C. (760 mmHg) of more than 0.5 g / L and are therefore not considered to be pigments.

[0291] Preferably, direct dyes within the meaning of the present invention have a water solubility at 25° C. (760 mmHg) of greater than 1.0 g / L.

[0292] Direct dyes can be divided into anionic, cationic and nonionic direct dyes.

[0293] In another embodiment, the process according to the invention is characterized in that the agent (b) comprises at least one coloring compound (b3) chosen from anionic, nonionic and cationic direct dyes.

[0294] Suitable cationic direct dyes include Basic Blue 7, Basic Blue 26, HC Blue 16, Basic Violet 2 and Basic Violet 14, Basic Yellow 57, Basic Red 76, Basic Blue 16, Basic Blue 347 (Cationic Blue 347 / Dystar), HC Blue No. 16, Basic Blue 99, Basic Brown 16, Basic Brown 17, Basic Yellow 57, Basic Yellow 87, Basic Orange 31, Basic Red 51, Basic Red 76.

[0295] As nonionic direct dyes, nonionic nitro and quinone dyes and neutral azo dyes can be used. Suitable nonionic direct dyes are those listed under the following international names or trade names: HC Yellow 2, HC Yellow 4, HC Yellow 5, HC Yellow 6, HC Yellow 12, HC Orange 1, Disperse Orange 3, HC Red 1, HC Red 3, HC Red 10, HC Red 11, HC Red 13, HC Red BN, HC Blue 2, HC Blue 11, HC Blue 12, Disperse Blue 3, HC Violet 1, Disperse Violet 1, Disperse Violet 4, Disperse Black 9 known compounds, as well as 1,4-diamino-2-nitrobenzene, 2-amino-4-nitrophenol, 1,4-bis-(2-hydroxyethyl)-amino-2-nitrobenzene, 3-nitro-4-(2-hydroxyethyl)-aminophenol , 2-(2-hydroxyethyl)amino-4,6-dinitrophenol, 4-[(2-hydroxyethyl)amino]-3-nitro-1-methylbenzene, 1-amino-4-(2-hydroxyethyl)-amino-5-chloro-2-nitrobenzene, 4-amino-3-nitrophenol, 1-(2'-ureidoethyl)amino-4-nitrobenzene, 2-[(4-amino-2-nitrophenyl)amino]benzoic acid, 6-nitro-1,2,3,4-tetrahydroquinoxaline, 2-hydroxy-1,4-naphthoquinone, picramic acid and its salts, 2-amino-6-chloro-4-nitrophenol, 4-ethylamino-3-nitrobenzoic acid and 2-chloro-6-ethylamino-4-nitrophenol.

[0296] Anionic direct dyes are also called acid dyes. Acid dyes are dyes that have at least one carboxylic acid group (-COOH) and / or one sulfonic acid group (-SO 3 H) direct dyes. Depending on the pH value, the protonated forms of the carboxylic acid or sulfonic acid groups (-COOH, -SO 3 H) and its deprotonated form (the presence of -COO - 、-SO 3 - ) is in balance. The ratio of protonated form increases with the reduction of pH. If direct dye is used in the form of its salt, the carboxylic acid group or sulfonic acid group exists in deprotonated form and is neutralized by the corresponding stoichiometric equivalent cation to maintain electrical neutrality. Acid dyes of the present invention can also be used in the form of its sodium salt and / or its potassium salt.

[0297] Acid dyes within the meaning of the present invention have a water solubility at 25°C (760 mmHg) greater than 0.5 g / L and are therefore not considered pigments. Preferably, acid dyes within the meaning of the present invention have a water solubility at 25°C (760 mmHg) greater than 1.0 g / L.

[0298] Alkaline earth metal salts (such as calcium and magnesium salts) or aluminum salts of acid dyes generally have lower solubility than the corresponding alkali metal salts. If the solubility of these salts is lower than 0.5 g / L (25° C., 760 mmHg), they do not fall within the definition of direct dyes.

[0299] The essential characteristic of acid dyes is their ability to form anionic charges, whereby the carboxylic acid or sulfonic acid groups responsible for this are usually linked to different chromophoric systems. Suitable chromophoric systems can be found, for example, in the structures of nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes and / or indophenol dyes.

[0300] In another embodiment, the method for dyeing keratin materials is characterized in that the agent (b) comprises at least one anionic direct dye (b3) selected from the group consisting of nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes and / or indophenol dyes, the dyes selected from the aforementioned group each having at least one carboxylic acid group (—COOH), sodium carboxylate group (—COONa), potassium carboxylate group (—COOK), sulfonic acid group (—SO 3 H), sodium sulfonate group (-SO 3 Na) and / or potassium sulfonate groups (-SO 3 K).

[0302] For example, the water solubility of anionic direct dyes can be determined in the following manner. 0.1 g of anionic direct dye is placed in a beaker. A stir bar is added. Then 100 ml of water is added. The mixture is heated to 25° C. on a magnetic stirrer while stirring. It is stirred for 60 minutes. The aqueous mixture is then visually evaluated. If there is still undissolved, the amount of water is increased—for example, in a gradient of 10 ml. Water is added until the amount of dye used is completely dissolved. If the dye-water mixture cannot be visually evaluated due to the high intensity of the dye, the mixture is filtered. If a portion of the undissolved dye remains on the filter paper, the solubility test is repeated with a higher amount of water. If 0.1 g of anionic direct dye is dissolved in 100 ml of water at 25° C., the solubility of the dye is 1.0 g / L.

[0312] Thus, in another embodiment, the method according to the invention is characterized in that the agent (b) comprises at least one direct dye (b3) selected from the group consisting of Acid Yellow 1, Acid Yellow 3, Acid Yellow 9, Acid Yellow 17, Acid Yellow 23, Acid Yellow 36, Acid Yellow 121, Acid Orange 6, Acid Orange 7, Acid Orange 10, Acid Orange 11, Acid Orange 15, Acid Orange 20, Acid Orange 24, Acid Red 14, Acid Red, Acid Red 27, Acid Red 33, Acid Red 35, Acid Red 51, Acid Red 52, Acid Red 73, Acid Red 87, Acid Red 92, Acid Red 103, Acid Red 104, Acid Red 105, Acid Red 106, Acid Red 107, Acid Red 108, Acid Red 109, Acid Red 111, Acid Red 112 C 95, Acid Red 184, Acid Red 195, Acid Violet 43, Acid Violet 49, Acid Violet 50, Acid Blue 1, Acid Blue 3, Acid Blue 7, Acid Blue 104, Acid Blue 9, Acid Blue 62, Acid Blue 74, Acid Blue 80, Acid Green 3, Acid Green 5, Acid Green 9, Acid Green 22, Acid Green 25, Acid Green 50, Acid Black 1, Acid Black 52, Food Yellow 8, Food Blue 5, D&C Yellow 8, D&C Green 5, D&C Orange 10, D&C Orange 11, D&C Red 21, D&C Red 27, D&C Red 33, D&C Violet 2, and / or D&C Brown 1.

[0313] Depending on the desired color intensity, direct dyes can be used in different amounts in agent (b). Good results can be obtained if agent (b) comprises - based on the total weight of agent (b) - a total amount of 0.01 to 10.0% by weight, preferably 0.1 to 8.0% by weight, more preferably 0.2 to 6.0% by weight, most preferably 0.5 to 4.5% by weight of one or more direct dyes (b3).

[0314] Furthermore, the agent (b) may also comprise at least one photochromic or thermochromic dye as coloring compound (b3).

[0315] Photochromic dyes are dyes that undergo a reversible change of color tone in response to irradiation with UV light (sunlight or black light). In the process, the UV light changes the chemical structure of the dyes and thus their absorption behavior (photochromic phenomenon).

[0316] Thermochromic dyes are dyes that undergo a reversible change of color tone in response to changes in temperature. In this process, changes in temperature change the chemical structure of the dyes and thus their absorption behavior (thermochromism phenomenon).

[0317] Agent (b) may contain - based on the total weight of the agent (b) - a total amount of 0.01 to 10.0 wt. %, preferably 0.1 to 8.0 wt. %, more preferably 0.2 to 6.0 wt. % and most preferably 0.5 to 4.5 wt. % of one or more photochromic dyes (b3).

[0318] Surfactant in the agent (b)

[0319] Since it contains water (b1) and a fat component (b2), the agent (b) is in the form of an emulsion. In order to further optimize the formation of the emulsion, it has proven particularly preferred to continue to use at least one surfactant in the agent (b).

[0320] Therefore, it is very preferred that the medicament (b) additionally comprises at least one surfactant.

[0321] In a further particularly preferred embodiment, the method according to the invention is characterized in that the agent (b) comprises at least one surfactant.

[0322] The term surfactant (T) refers to surface-active substances which can form adsorbed layers on surfaces and interfaces or aggregate in the bulk phase to form micellar colloids or lyotropic mesophases. A distinction is made between anionic surfactants consisting of a hydrophobic residue and a negatively charged hydrophilic head group, amphoteric surfactants with a negative charge and a compensating positive charge, cationic surfactants which, in addition to the hydrophobic residue, also have a positively charged hydrophilic group, and nonionic surfactants which have no charge but have a strong dipole moment and are strongly hydrated in aqueous solution.

[0323] In a very particularly preferred embodiment, the process according to the invention is characterized in that the agent (b) comprises at least one nonionic surfactant (b4).

[0324] Nonionic surfactants contain, for example, polyol groups, polyalkylene glycol ether groups or a combination of polyol and polyethylene glycol ether groups as hydrophilic groups. Such surfactants include:

[0325] - addition products of 2 to 50 mol of ethylene oxide and / or 0 to 5 mol of propylene oxide with linear and branched fatty alcohols having 6 to 30 carbon atoms, fatty alcohol polyethylene glycol ethers or fatty alcohol polypropylene glycol ethers or mixed fatty alcohol polyethers,

[0326] - addition products of 2 to 50 mol of ethylene oxide and / or 0 to 5 mol of propylene oxide with linear and branched fatty acids having 6 to 30 carbon atoms, fatty acid polyglycol ethers or fatty acid polypropylene glycol ethers or mixed fatty acid polyethers,

[0328] - 2 to 50 mol of ethylene oxide and / or 0 to 5 mol of propylene oxide with linear and branched fatty alcohols having 8 to 30 carbon atoms, with fatty acids having 8 to 30 carbon atoms and with the methyl or C 2-6 radicals of alkylphenols having 8 to 15 carbon atoms in the alkyl group;2 -C 6 - alkyl end-capped addition products, such as those sold under the name LS, Products available from LT(Cognis),

[0329] -1 to 30 mol of the addition product of ethylene oxide and glycerol 12 -C 30 Fatty acid monoesters and diesters,

[0334] R 1 CO-(OCH 2 CHR 2 ) w OR 3 (Tnio-1)

[0335] Where R 1 CO is a straight chain or branched, saturated and / or unsaturated acyl group having 6 to 22 carbon atoms, R 2 is hydrogen or methyl, R 3 is a straight or branched alkyl group having 1 to 4 carbon atoms, w is a number from 1 to 20,

[0341] - Sugar tensides of the alkyl and alkenyl oligoglycoside type according to formula (E4-II):

[0342] R4 O-[G] p (Tnio-2)

[0343] Where R 4 It is an alkyl or alkenyl group containing 4 to 22 carbon atoms, G is a sugar residue containing 5 or 6 carbon atoms, and p is a number from 1 to 10. They can be obtained by relevant organic chemical preparation methods. Alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses having 5 or 6 carbon atoms, preferably glucose. Preferred alkyl and / or alkenyl oligoglycosides are therefore alkyl and / or alkenyl oligoglycosides. The index p in the general formula (Tnio-2) represents the degree of oligomerization (DP), that is, the distribution of monoglycosides and oligoglycosides, representing a number from 1 to 10. Although p must always be an integer in a single molecule and can take the value p=1 to 6, the p value for a certain alkyl oligoglycoside is an analytically determined arithmetic quantity, usually expressed as a fraction. It is preferred to use alkyl and / or alkenyl oligoglycosides with an average oligomerization degree p of 1.1 to 3.0. From the point of view of application technology, preference is given to those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and between 1.2 and 1.4. 4 It can be derived from primary alcohols containing 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, hexanol, octanol, decanol and undecanol and their technical mixtures, such as those obtained during the hydrogenation of industrial fatty acid methyl esters or during the hydrogenation of aldehydes from Roelen oxo synthesis. Preferred are those with a chain length of C 8 -C 10 (DP = 1 to 3) alkyl oligoglycosides, which are used as distillation separation industrial C 8 -C 18 Coconut fatty alcohol is obtained in the preliminary step and may be contaminated with less than 6 wt.% of C 12 Alcohols, and industrial C 9 / 11 Alkyl oligoglucosides of oxoalcohols (DP = 1 to 3). Alkyl or alkenyl R 15 It can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmityl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidic alcohol, petroselinol, arachidyl alcohol, eicosene alcohol, behenyl alcohol, erucic acid, basil alcohol and the technical mixtures obtainable as described above. Preferred are hardened C 12 / 14 Alkyl oligoglycosides of coconut alcohol having a DP of 1 to 3.

[0344] - Sugar-based surfactants of fatty acid N-alkyl polyhydroxyalkylamide type, nonionic surfactants of formula (Tnio-3):

[0345] R 5CO-NR 6 -[Z] (Tnio-3)

[0346] Where R 5 CO is an aliphatic acyl group containing 6 to 22 carbon atoms, R 6 is hydrogen, an alkyl group or a hydroxyalkyl group containing 1 to 4 carbon atoms, and [Z] is a straight-chain or branched polyhydroxyalkyl group containing 3 to 12 carbon atoms and 3 to 10 hydroxyl groups. Fatty acid N-alkyl polyhydroxyalkylamides are known substances and can generally be obtained by reductive amination of reducing sugars with ammonia, alkylamines or alkanolamines and subsequent acylation with fatty acids, fatty acid alkyl esters or fatty acid chlorides. Fatty acid N-alkyl polyhydroxyalkylamides are preferably derived from reducing sugars having 5 or 6 carbon atoms, especially glucose. Preferred fatty acid N-alkyl polyhydroxyalkylamides are therefore fatty acid N-alkyl glucamides represented by the formula (Tnio-4):

[0347] R 7 CO-(NR 8 )-CH 2 –[CH(OH)] 4 –CH 2 OH (Tnio-4)

[0348] Preferably, glucamides of formula (Tnio-4) are used as fatty acid-N-alkyl polyhydroxyalkylamides, wherein R 8 represents hydrogen or alkyl, R 7 CO represents the acyl radical of the following acids: caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arachidic acid, eicosenoic acid, behenic acid or erucic acid or their technical mixtures. Particularly preferred are fatty acid N-alkylglucamides of the formula (Tnio-4), which are obtained by reductive amination of glucose with methylamine and subsequent acylation with lauric acid or C12 / 14 coconut fatty acids or corresponding derivatives. In addition, polyhydroxyalkylamides can also be derived from maltose and palatinose.

[0349] The sugar surfactant may preferably be present in the medicament used according to the present invention in an amount of 0.1-20 wt.% based on the total medicament. An amount of 0.5-15 wt.% is preferred, and an amount of 0.5-7.5 wt.% is particularly preferred.

[0350] Other typical examples of nonionic surfactants are fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, protein hydrolysates (especially wheat-based vegetable products) and polysorbates in mixed ether or mixed form.

[0351] Alkylene oxide addition products of saturated linear fatty alcohols and fatty acids, with 2 to 30 mol of alkylene oxide per mole of fatty alcohol or fatty acid, and sugar surfactants have proven to be preferred nonionic surfactants. Formulations with excellent properties can also be obtained if they contain fatty acid esters of ethoxylated glycerol as nonionic surfactants.

[0352] These aspects are confirmed by the following parameters. The alkyl group R contains 6 to 22 carbon atoms and can be straight or branched. Aliphatic groups with primary straight chains and 2-methyl branches are preferred. Such alkyl groups are, for example, 1-octyl, 1-decyl, 1-dodecyl, 1-tetradecyl, 1-hexadecyl and 1-octadecyl. Particularly preferred are 1-octyl, 1-decyl, 1-dodecyl, 1-tetradecyl. When so-called "oxo-alcohols" are used as starting materials, compounds with an odd number of carbon atoms in the alkyl chain predominate.

[0353] The compounds with alkyl groups used as surfactants can all be homogeneous substances. In the production of these substances, however, it is generally preferred to start from natural plant or animal raw materials in order to obtain mixtures of substances with different alkyl chain lengths, depending on the respective raw material.

[0354] For surfactants which are addition products of ethylene oxide and / or propylene oxide to fatty alcohols or derivatives of these addition products, both products with a "normal" homologue distribution and those with a narrow homologue distribution can be used. A "normal" homologue distribution refers to the homologue mixture obtained in the reaction of fatty alcohols and alkylene oxides using alkali metals, alkali metal hydroxides or alkali metal alkoxides as catalysts. On the other hand, when, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alkoxides are used as catalysts, a narrowed homologue distribution is obtained. Products with a narrow homologue distribution can preferably be used.

[0355] Particularly good results are obtained when an agent (b) comprising at least one ethoxylated fatty alcohol having a degree of ethoxylation of 10 to 40 is used in the method according to the invention.

[0356] In a further very particularly preferred embodiment, the process according to the invention is characterized in that the agent (b) comprises at least one nonionic surfactant (b4) of the formula (TI),

[0357]

[0358] in

[0359] Rb is a saturated or unsaturated, straight chain or branched chain C 8 -C 24 Alkyl, preferably saturated straight chain C16 -C 18 Alkyl, and

[0360] m is an integer from 10 to 40, preferably an integer from 20 to 35, and the number 30 is particularly preferred.

[0361] A particularly suitable nonionic surfactant of this type is ceteareth-30. Ceteareth-30 is a mixture of cetyl alcohol and stearyl alcohol each ethoxylated with 30 units of ethylene oxide. A mixture of cetyl alcohol and stearyl alcohol is called cetearyl alcohol. Ceteareth-30 has the CAS number 68439-49-6 and can be purchased, for example, from BASF under the trade name Eumulgin B3.

[0362] Nonionic surfactants, in particular nonionic surfactants of formula (TI), are preferably used in the medicament (b) in a suitable amount range. Thus, based on the total weight of the medicament (b), the medicament (b) may contain a total amount of 0.1 to 20 wt %, preferably 0.2 to 10 wt %, more preferably 0.3 to 5 wt %, most preferably 0.4 to 2.5 wt % of one or more nonionic surfactants.

[0363] Aminosilicone not used in agent (b)

[0364] In step (3) of the method according to the invention, agents (a) and (b) are mixed and a ready-to-use colorant is prepared in this way, which is then applied to the hair (step (4)), allowed to act (step (5)) and rinsed out again (step (6)).

[0365] As mentioned above, the agent (a) is preferably a concentrate of aminosilicone (a1), which meets the coloring compound (i.e. pigment) (b3) only shortly before application. The mixing initiates a reaction or interaction between the aminosilicone (a1) and the pigment (b3), which ultimately leads to polymerization, accumulation or aggregation of (a1) and (b3) under the conditions of use, and in this way is believed to fix the pigment on the surface of the keratin fibers.

[0366] In order to obtain a uniform color result on the keratin fibers, it was found to be crucial in this case that this interaction of (a1) and (b3) is initiated only shortly before or during the dyeing process and that co-storage of (a1) and (b3) is avoided. For this reason, it was further found to be very particularly preferred that the agent (b) itself does not contain any aminosilicone.

[0367] In a further specifically very particularly preferred embodiment, the process according to the invention is characterized in that the total content of amino-functional silicone polymers in agent (b)—based on the total weight of agent (b)—is less than 1.0% by weight, preferably less than 0.5% by weight, more preferably less than 0.1% by weight, very particularly preferably less than 0.01% by weight.

[0368] In other words, in a further specifically very particularly preferred embodiment, the process according to the invention is characterized in that agent (b) comprises - based on the total weight of agent (b) - a total amount of 0 to 1.0% by weight, preferably 0 to 0.5% by weight, more preferably 0 to 0.1% by weight, very particularly preferably 0 to 0.01% by weight of one or more amino-functional silicone polymers.

[0369] It is obviously very preferred that agent (b) does not contain any amino-functional silicone polymers.

[0370] Other optional ingredients in the pharmaceutical composition (a) and / or (b)

[0371] In addition to the essential components of the present invention that have been described, the medicaments (a) and / or (b) may also contain other optional components.

[0377] Other film-forming polymers can be selected from homopolymers or copolymers of (meth)acrylamide, N-alkyl(meth)acrylamide, especially those with C2-C18 alkyl groups, such as N-ethylacrylamide, N-tert-butylacrylamide, N-octylacrylamide; N-di(C1-C4)alkyl(meth)acrylamide.

[0378] Other preferred anionic copolymers are, for example, copolymers of acrylic acid, methacrylic acid or their C1-C6 alkyl esters, such as sold under the INCI claim acrylate copolymers. Suitable commercial products are, for example, acrylates from Rohm & Haas 33. Acrylic acid, methacrylic acid or C 1 -C 6 Copolymers of alkyl esters with esters of ethylenically unsaturated acids and alkoxylated fatty alcohols are also preferred. Suitable ethylenically unsaturated acids are especially acrylic acid, methacrylic acid and itaconic acid; suitable alkoxylated fatty alcohols are especially Steareth-20 or Ceteth-20.

[0379] Very particularly preferred polymers on the market are for example (Acrylates / Steareth-20 Methacrylate Copolymer), 28 (Acrylates / Beheneth-25 Methacrylate Copolymer), Structure (Acrylates / Steareth-20 Itaconate Copolymer), SStructure (Acrylates / Ceteth-20 Itaconate Copolymer), Structure (Acrylates / C10-30 Alkyl Aminoacrylate PEG-20 Itaconate Copolymer), 1342, 1382, Ultrez 20, Ultrez 21 (Acrylates / C10-30 Alkyl Acrylate Crosspolymer), Synthalen W (Acrylates / C12-22 Alkyl Methacrylate Copolymer) or Soltex OPT (Acrylates / C12-22 Alkyl Methacrylate Copolymer) distributed by Rohme und Haas.

[0381] In addition, copolymers such as octylacrylamide / acrylates / butylaminoethyl methacrylate copolymers, such as those sold by NATIONAL STARCH under the trade name or 47 Commercially available; or sold by NATIONAL STARCH under the trade name LT and 79 Commercially available acrylate / octylacrylamide copolymers are particularly suitable.

[0382] Suitable olefin-based polymers include homopolymers and copolymers of ethylene, propylene, butylene, isoprene, and butadiene.

[0383] In another form, block copolymers comprising at least one styrene or styrene derivative block can be used as the film-forming hydrophobic polymer. These block copolymers can be copolymers comprising one or more other blocks in addition to the styrene block, such as styrene / ethylene, styrene / ethylene / butylene, styrene / butylene, styrene / isoprene, styrene / butadiene. Such polymers are commercially distributed by BASF under the trade name "Luvitol HSB".

[0384] In another embodiment, the method according to the invention is characterized in that the agents (a) and / or (b) comprise at least one film-forming polymer selected from the group consisting of polyvinylpyrrolidone (PVP), vinylpyrrolidone / vinyl acetate copolymers, vinylpyrrolidone / styrene copolymers, vinylpyrrolidone / ethylene copolymers, vinylpyrrolidone / propylene copolymers, vinylpyrrolidone / vinyl caprolactam copolymers, vinylpyrrolidone / vinyl formamide copolymers and / or vinylpyrrolidone / vinyl alcohol copolymers, copolymers of acrylic acid, copolymers of methacrylic acid, homopolymers or copolymers of acrylates, homopolymers or copolymers of methacrylates, homopolymers or copolymers of acrylic acid amides, homopolymers or copolymers of methacrylic acid amides, copolymers of vinylpyrrolidone, copolymers of vinyl alcohol, copolymers of vinyl acetate, homopolymers or copolymers of ethylene, homopolymers or copolymers of propylene, homopolymers or copolymers of styrene, polyurethanes, polyesters and / or polyamides.

[0385] Preferably, one or more film-forming polymers are used in an amount within a specific range for the agents (a) and / or (b). In this regard, it has proven particularly preferred for achieving the object according to the invention that the agent (b) comprises—based on the total weight of the agent (b)—a total amount of 0.1 to 25.0 wt. %, preferably 0.2 to 20.0 wt. %, more preferably 0.5 to 15.0 wt. %, very particularly preferably 1.0 to 7.0 wt. % of one or more polymers.

[0386] The medicament may also contain one or more surfactants. The term surfactant refers to a surface-active substance. A distinction is made between anionic surfactants consisting of a hydrophobic residue and a negatively charged hydrophilic head group, amphoteric surfactants with a negative charge and a compensating positive charge, cationic surfactants which have a positively charged hydrophilic group in addition to the hydrophobic residue, and nonionic surfactants which have no charge but have a strong dipole moment and are strongly hydrated in aqueous solution.

[0387] Zwitterionic surfactants are surfactants with at least one quaternary ammonium group and at least one -COO (-) or -SO 3 (-)Particularly suitable zwitterionic surfactants are the so-called betaines, for example N-alkyl-N,N-dimethylammonium glycinates, for example cocoalkyl-dimethylammonium glycinates, N-acylaminopropyl-N,N-dimethylammonium glycinates, for example cocoacylaminopropyldimethylammonium glycinates, and 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines, each having 8 to 18 C atoms in the alkyl or acyl radical, and cocoacylaminoethyl hydroxyethylcarboxymethylglycinate. Preferred zwitterionic surfactants are the fatty acid amide derivatives known under the INCI name cocamidopropyl betaine.

[0388] Amphoteric surfactants are surface-active compounds that, in addition to C 8 -C 24 In addition to an alkyl or acyl group, the molecule also contains at least one free amino group and at least one -COOH- or -SO 3 H groups, and can form inner salts. Examples of suitable amphoteric surfactants are N-alkylglycine, N-alkylpropionic acid, N-alkylaminobutyric acid, N-alkyliminodipropionic acid, N-hydroxyethyl-N-alkylaminopropylglycine, N-alkyltaurine, N-alkylsarcosine, 2-alkylaminopropionic acid and alkylaminoacetic acid, which all have about 8 to 24 C atoms in the alkyl group. Typical examples of amphoteric or zwitterionic surfactants are alkyl betaines, alkylamide betaines, aminopropionates, aminoglycinates, imidazolinium betaines and sulfobetaines.

[0389] Particularly preferred amphoteric surfactants are N-cocoalkylaminopropionate, cocoylaminoethylaminopropionate and C 12 -C 18 Acylsarcosine.

[0390] In addition, the medicament may also contain at least one cationic surfactant. Cationic surfactants are surfactants, i.e. surface-active compounds, that carry one or more positive charges. Cationic surfactants contain only positive charges. Typically, these surfactants consist of a hydrophobic portion, which is typically composed of a hydrocarbon backbone (e.g., composed of one or two straight or branched alkyl chains), and a hydrophilic head group, wherein the positive charge is located in the hydrophilic head group. Examples of cationic surfactants are:

[0391] - quaternary ammonium compounds which may carry one or two alkyl chains with a chain length of 8 to 28 C atoms as hydrophobic groups,

[0392] - a quaternary phosphonium salt substituted by one or more alkyl chains having a chain length of 8 to 28 C atoms, or

[0393] -tert-sulfonium salts.

[0394] Furthermore, the cationic charge can also be part of a heterocyclic ring (e.g., an imidazole ring or a pyridine ring) in the form of an onium structure. In addition to the functional groups with a cationic charge, the cationic surfactants can also contain other uncharged functional groups, for example in the case of ester quaternary ammonium salts. The total amount of the cationic surfactant used is 0.1 to 45 wt.%, preferably 1 to 30 wt.%, and most preferably 1 to 15 wt.%, based on the total weight of the corresponding medicament.

[0395] In addition, the medicament according to the invention may also contain at least one anionic surfactant. Anionic surfactants are surfactants that have only anionic charge (neutralized by the corresponding counter cation). Examples of anionic surfactants are fatty acids, alkyl sulfates, alkyl ether sulfates and ether carboxylic acids with 12 to 20 C atoms in the alkyl group and up to 16 glycol ether groups in the molecule.

In the context of the present invention, two possible enantiomers can be used equally as a specific compound or a mixture thereof, in particular in the form of a racemate. However, it is particularly advantageous to use the naturally preferred isomeric form, usually in the L configuration.

[0420] The basic amino acid is preferably selected from arginine, lysine, ornithine and histidine, particularly preferably arginine and lysine. Therefore, in another particularly preferred embodiment, the medicament according to the invention is characterized in that the alkalizing agent is a basic amino acid selected from arginine, lysine, ornithine and / or histidine.

[0421] In addition, the product may contain other alkalizing agents, especially inorganic alkalizing agents.

[0429] Apply the application mixture to the keratin material

[0430] In step (5) of the method according to the invention, the application mixture is allowed to act on the keratin material after its application. In this regard, different action times of, for example, 30 seconds to 60 minutes are conceivable.

[0431] However, the main advantage of the dyeing system according to the invention is that an intense color result can be achieved in a very short time even after a short action time. For this reason, it is advantageous if the application mixture remains on the keratin material only for a relatively short time after its application, of 30 seconds to 15 minutes, preferably 30 seconds to 10 minutes, particularly preferably 1 to 5 minutes.

[0432] In another preferred embodiment, the method according to the invention is characterized in that:

[0436] In one embodiment, the application mixture can be washed off with water alone, ie without the aid of post-treatment agents or shampoos. In principle, it is also conceivable to use post-treatment agents or conditioners in step (6).

[0437] However, in order to achieve the object according to the invention and to increase the ease of use, it has proven particularly preferred to rinse the application mixture in step (6) only with water without the aid of further aftertreatment agents, without shampoo and without conditioner.

[0438] In another preferred embodiment, the method according to the invention is characterized in that:

[0439] (6) Use the mixture only by flushing with water.

[0442] In step (1), agent (a) is provided, and step (2) includes providing agent (b).

[0443] These two steps do not necessarily have to be performed one after the other, but can also be performed simultaneously.

[0444] Thus, step (1) may occur before step (2), steps (1) and (2) may occur simultaneously, or step (2) may occur before step (1).

[0445] For example, if medicaments (a) and (b) are provided to the user in a multi-component packaging unit, both medicaments are provided simultaneously and it is up to the user to decide which medicament to remove from the packaging first.

[0446] The preparation of the administration mixture by mixing agents (a) and (b) in step (3) can only be carried out after both agents (a) and (b) have been provided.

[0447] The application of the application mixture in step (4) can only be carried out after it has been prepared in step (3).

[0448] Similarly, the application mixture in step (5) may be applied after it has been applied to the keratin material, and rinsing of the application mixture in step (6) may be performed after it has been applied in step (5).
