Description

Technical Field

[0001] The subject of the present application is a method for dyeing keratinous materials, in particular human hair, which comprises the application of at least two different agents (a) and (b). Agent (a) is a premix or concentrate comprising at least one amino-functionalized silicone polymer (a1) and at least one coloring compound (a2). Agent (b) is a carrier preparation which contains at least one fatty component (b2) and is characterized by a low water content. Before application, the application mixture to be applied to the keratin material is prepared by mixing agent (a) and agent (b), applied to the keratinous material, allowed to act, and then rinsed off again.

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

[0003] A third subject of the present application is a ready-to-use colorant obtained by mixing two agents (a) and (b).

Background Art

[0004] Changing the shape and color of keratin fibers, especially hair, is an important area of modern cosmetics. To change the color of hair, experts know various coloring systems according to the requirements of coloring. For long-lasting strong dyeing with good fastness and good gray hair coverage, oxidation dyes are usually used. Such dyes usually contain oxidation dye precursors (so-called developing components) and coloring components, which, under the influence of an oxidizing agent such as hydrogen peroxide, produce the actual dye with each other. Oxidation dyes are characterized by a very long-lasting dyeing result.

[0005] When using direct dyes, the already prepared dye diffuses from the colorant into the hair fibers. Compared with oxidative hair dyeing, the dyed products obtained using direct dyes have a shorter color retention time and better washability. Dyeing with direct dyes usually remains on the hair during 5 to 20 washings.

[0006] The use of coloring pigments is known for changing the color of hair and / or skin in a short period of time. Coloring pigments are understood to be insoluble coloring substances. Coloring pigments exist as small particles without dissolving in the dye composition and adhere only to the surface of hair fibers and / or skin from the outside. Therefore, coloring pigments can usually be removed without residue by washing several times with a detergent containing a surfactant. Various products of this type are commercially available under the name "hair mascara".

[0007] The advantage of hair mascara products is that coloring compounds such as pigments deposit only in film form on the surface of keratin fibers. Therefore, since the properties of the keratin fibers themselves do not change during the application of the product, the use of hair mascara products is particularly unlikely to damage the hair. If the user wants to return to the original hair color, the dye can be quickly and completely removed from the keratin fibers without damaging the fibers or changing the original hair color. Therefore, the development of pigment-based keratin colorants fully follows this trend.

[0008] However, as before, optimization of this dyeing method is still necessary, and there is still a need to improve the color intensity and the feel of the hair or the grip of the keratin fibers. Summary of the Invention Problems to be Solved by the Invention

[0009] The problem of the present invention is to provide, if possible, a dyeing method having fastness comparable to oxidative dyeing. The washing fastness must be remarkable, but the use of oxidative dye precursors commonly used for this purpose must be avoided. There is a need for a technique that enables coloring compounds (especially pigments) known from the prior art to be fixed to the hair in a very durable manner. When an agent is used in the dyeing process, a strong dyeing result with excellent fastness must be obtained. A particular focus of the problem is to achieve a strong coloring result and a good hair feel at the same time. Means for Solving the Problems

[0010] Surprisingly, it has been found that the above problems can be excellently solved by dyeing keratin materials, especially hair, using a procedure of applying at least two agents (a) and (b) to the keratin material (hair). Here, agent (a) contains at least one amino-functionalized silicone polymer (a1) and at least one coloring compound (a2). Agent (a) is preferably low-water or anhydrous and is in the form of a premix or concentrate containing components (a1) and (a2) as main components. Before use, agent (a) is mixed with a cosmetic carrier preparation which contains at least one fatty component (b2) and is in the form of agent (b) characterized by a low water content. Then, the application mixture prepared by mixing agent (a) and agent (b) is applied to the keratin material, allowed to act, and then rinsed again with water.

[0011] The first object of the present invention is the following steps: (1) Providing agent (a) containing (a1) at least one amino-functionalized silicone polymer and (a2) at least one coloring compound ; (2) Based on the total weight of agent (b), (b1) 0 to 50% by weight of water and (b2) at least one fatty component ; (3) Mixing agent (a) and agent (b) to prepare an application mixture; (4) Applying the application mixture prepared in step (3) to the keratin material; (5) Exposing the keratin material to the application mixture applied in step (4); and (6) Rinsing the application mixture away with water, which is a method for dyeing keratin materials, especially human hair.

[0012] In the research leading to the present invention, it has been shown that when agent (a) is provided in the form of the above-mentioned premix or concentrate (this premix (a) is only mixed with the carrier preparation (b) immediately before application), a particularly strong staining result is obtained on keratinous substances. Surprisingly, the application mixture obtained by mixing the two agents (a) and (b) immediately before application gives a stronger staining result compared to a preparation that is identical except that it initially contains all the components of the two agents (a) and (b). Furthermore, it has been found that a reduction in the water content in agent (b) leads to an improvement in the grip feeling of keratin fibers.

Mode for Carrying Out the Invention

[0013] <Keratinous substance> Keratinous substances include hair, skin, nails (e.g., fingernails and / or toenails). Wool, fur, and feathers are also included in the definition of keratinous substances.

[0014] Preferably, keratinous substances are understood to be human hair, human skin, and human nails (in particular, fingernails and toenails). Keratinous substances are understood to be human hair.

[0015] <Agent (a)> In step (1) of the method according to the invention, agent (a) is provided. For example, agent (a) can be present in a packaging unit or container, thereby enabling use by the user. The container can be, for example, a sachet, bottle, can, jar, or other container suitable for cosmetic preparations.

[0016] Agent (a) is characterized by the contents of the essential components (a1) and (a2) of the present invention.

[0017] <Amino-functionalized silicone polymer (a1) in agent (a)> As the first component (a1) essential to the present invention, agent (a) contains at least one amino-functionalized silicone polymer. The amino-functionalized silicone polymer may also be abbreviated as aminosilicone or amodimethicone.

[0018] The silicone polymer is a macromolecule having a molecular weight of at least 500 g / mol, preferably at least 1000 g / mol, more preferably at least 2500 g / mol, and particularly preferably at least 5000 g / mol, and contains repeating organic units.

[0019] 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 partly determined by the polymerization method. For the purposes of the present invention, the maximum molecular weight of the silicone polymer is 10 7 g / mol or less, preferably 10 6 g / mol or less, and particularly preferably 10 5 g / mol or less.

[0020] The silicone polymer contains many Si-O repeating units, and the Si atoms may have organic groups, such as alkyl groups or substituted alkyl groups. Therefore, the silicone polymer is also referred to as polydimethylsiloxane.

[0021] Depending on its high molecular weight, the silicone polymer is 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, and most preferably more than 500 Si-O repeating units.

[0022] The amino-functionalized silicone polymer is understood to be a functionalized silicone containing at least one structural unit having an amino group. Preferably, the amino-functionalized silicone polymer has a plurality of structural units each having at least one amino group. The 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 exist in a cationic form.

[0023] Basically, when the amino-functionalized silicone polymer (a1) has at least one primary amino group, at least one secondary amino group and / or at least one tertiary amino group, beneficial effects are obtained by the amino-functionalized silicone polymer (a1). However, in the agent (a), when an amino-functionalized silicone polymer (a1) having at least one secondary amino group is used, the most wash-fast and strong dyeing was observed.

[0024] In a very particularly preferred embodiment, the method of the present invention is characterized in that the agent (a) comprises at least one amino-functionalized silicone polymer (a1) having at least one secondary amino group.

[0025] One or more secondary amino groups may be present at various positions in the amino-functionalized silicone polymer. In the formula (Si-amino): Particularly beneficial results were seen when using an amino-functionalized silicone polymer (a1) having at least one, preferably a plurality of, structural units represented by TIFF0007717056000001.tif7674.

[0026] In the structural unit represented by the formula (Si-amino), the abbreviations ALK1 and ALK2 are independently linear or branched divalent C1-C 20 represent an alkylene group.

[0027] In another very particularly preferred embodiment, the method of the present invention is characterized in that the agent (a) comprises at least one amino-functionalized silicone polymer (a1) comprising at least one structural unit represented by the formula (Si-amino): TIFF0007717056000002.tif7674 [wherein ALK1 and ALK2 independently represent a linear or branched divalent C1-C 20 represent an alkylene group] and comprises at least one.

[0028] The positions indicated by an asterisk (*) represent the attachment to another structural unit of the silicone polymer. For example, the silicon atom adjacent to the asterisk may be attached to another oxygen atom, and the oxygen atom adjacent to the asterisk may be attached to another silicon atom or even a C1-C6 alkyl group.

[0029] Alternatively, a divalent C1-C 20 The alkylene group is sometimes referred to as a divalent C1-C 20 alkylene group, which means that each of the ALK1 and ALK2 groups can form two bonds.

[0030] In the case of ALK1, one bond occurs from the silicon atom to the ALK1 group, and a second bond exists between ALK1 and the secondary amino group.

[0031] In the case of ALK2, one bond exists from the secondary amino group to ALK2, and a second bond exists between ALK2 and the primary amino group.

[0032] Straight-chain divalent C1-C 20 Examples of alkylene groups include a methylene group (-CH2-), an ethylene group (-CH2-CH2-), a propylene group (-CH2-CH2-CH2-), and a butylene group (-CH2-CH2-CH2-CH2-). The propylene group (-CH2-CH2-CH2-) is particularly preferred. From the chain length of three carbon atoms, the divalent alkylene group may be branched. Branched-chain divalent C3- 20 Examples of alkylene groups are (-CH2-CH(CH3)-) and (-CH2-CH(CH3)-CH2-).

[0033] In another particularly preferred embodiment, the structural unit represented by the formula (Si-amino) represents a repeating unit in the amino-functionalized silicone polymer (a1), so the silicone polymer contains a plurality of structural units represented by the formula (Si-amino).

[0034] Particularly suitable amino-functionalized silicone polymers (a1) having at least one secondary amino group are listed below.

[0035] In the method of the present invention, the structural unit represented by formula (Si-I) and the structural unit represented by formula (Si-II): When at least one agent (a) containing at least one amino-functionalized silicone polymer (a1) containing TIFF0007717056000003.tif80142 is applied to a keratinous substance, a dyeing having good washing fastness is obtained.

Heat this mixture at 25 °C for 1 hour while stirring with a magnetic stirrer. If undissolved components of the pigment are visible in the mixture even after this time has elapsed, the solubility of the pigment is less than 0.5 g / L. If the pigment-water mixture cannot be visually evaluated due to the high intensity of the finely dispersed pigment, filter the mixture. If undissolved pigment remains on the filter paper, the solubility of that pigment is less than 0.5 g / L.

[0066] Suitable coloring pigments may be of inorganic origin and / or organic origin.

[0068] Preferred coloring pigments are selected from synthetic or natural inorganic pigments. Inorganic coloring pigments of natural origin can be prepared, for example, from chalk, loess, amber, green earth, calcined terra di siena or graphite. Also, black pigments such as black iron oxide, colored pigments such as ultramarine or red iron oxide, and fluorescent or phosphorescent pigments can be used as inorganic coloring pigments.

[0069] Colored metal oxides, metal hydroxides and metal oxide hydrates, mixed-phase pigments, sulfur-containing silicates, silicates, metal sulfates, double metal cyanides, metal sulfates, chromates and / or molybdates are particularly suitable.

[0070] In the present invention, colored nacreous pigments are also particularly preferred coloring pigments. These are usually based on mica and / or mica, and may be coated with one or more metal oxides. Mica belongs to the phyllosilicates. The most important representative examples of these silicates are muscovite, phlogopite, soda mica, biotite, lepidolite and margarite. To produce nacreous pigments combined with metal oxides, mica such as muscovite or phlogopite is coated with metal oxides.

[0071] As an alternative to natural mica, synthetic mica coated with one or more metal oxides can be used as a nacreous pigment. Particularly preferred nacreous pigments are those based on natural or synthetic mica (mica) and coated with one or more of the above-mentioned metal oxides. By varying the thickness of the layer of metal oxide, the color of each pigment can be changed.

[0072] In another preferred embodiment, the method of the present invention is characterized in that agent (a) comprises at least one coloring compound (a2) selected preferably from the group of inorganic pigments consisting of colored metal oxides, metal hydroxides, metal oxide hydrates, silicates, metal sulfates, double metal cyanides, metal sulfates, bronze pigments, and / or from the group of colored mica or mica-based pigments coated with at least one metal oxide and / or metal oxychloride.

[0081] In another particularly preferred embodiment, in the method of the present invention, the agent (a) is selected preferably from the group of organic pigments consisting of carmine, quinacridone, phthalocyanine, sorghum, blue pigments with Color Indexes of Cl42090, CI69800, CI69825, CI73000, CI74100, CI74160, yellow pigments with Color Indexes of CI11680, CI11710, CI15985, CI19140, CI20040, CI21100, CI21108, CI47000, CI47005, green pigments with Color Indexes of CI61565, CI61570, CI74260, orange pigments with Color Indexes of CI11725, CI15510, CI45370, CI71105, and red pigments with Color Indexes of CI12085, CI12120, CI12370, CI12420, CI12490, CI14700, CI15525, CI15580, CI15620, CI15630, CI15800, CI15850, CI15865, CI15880, CI17200, CI26100, CI45380, CI45410, CI58000, CI73360, CI73915 and / or CI75470, and is characterized by containing at least one coloring compound (a2) from the group of organic pigments thus selected.

[0082] The organic pigment may be a color paint. In the context of the present invention, the term "color lacquer" means particles comprising a layer of absorbed dye, and the units of particles and dye are insoluble under the above conditions. The particles can be, for example, inorganic substances, which can be aluminum, silica, calcium borosilicate, calcium aluminum borosilicate or aluminum.

[0083] For example, alizarin color varnish can be used.

[0084] Due to the excellent stability against light and temperature, it is particularly preferred to use the above pigments in the agent (a) of the method of the present invention. Also, it is preferred that the pigments used have a specific particle size. Thus, in the present invention, 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 It is advantageous to have an average particle size D 50 which can be measured, for example, using dynamic light scattering (DLS).

[0085] The coloring compound (a2), which is a coloring compound from the group of pigments, represents the second component of the agent (a) or the premix in the present invention. As a further main component (a2), very preferably, in the agent (a), the pigment is used in a correspondingly large amount. Particularly satisfactory results were obtained when the agent (a) contained one or more pigments in a total amount of 2.0 to 95.0% by weight, preferably 4.0 to 70.0% by weight, more preferably 6.0 to 50.0% by weight, and most preferably 8.0 to 30.0% by weight based on the total weight of the agent (a).

[0086] In another very particularly preferred embodiment, the agent in the present invention is characterized in that the agent (a) contains one or more pigments in a total amount of 2.0 to 95.0% by weight, preferably 4.0 to 70.0% by weight, more preferably 6.0 to 50.0% by weight, and most preferably 8.0 to 30.0% by weight based on the total weight of the agent (a).

[0087] As the coloring compound (a2), the agent (a) used in the method of the present invention may contain one or more direct dyes. A direct-acting dye is a dye that acts directly on the hair and does not require an oxidation step to form a color. Direct dyes are usually nitrophenylenediamine, nitroaminophenol, azo dyes, anthraquinone, triarylmethane dyes, or indophenol.

[0088] The direct dye in the meaning of the present invention has a solubility in water at 25°C (760 mmHg) greater than 0.5 g / L and is thus not treated as a pigment. Preferably, the direct dye in the meaning of the present invention has a solubility in water at 25°C (760 mmHg) greater than 1.0 g / L.

[0089] Direct dyes can be classified into anionic direct dyes, cationic direct dyes, and non-ionic direct dyes.

[0090] In another preferred embodiment, the method of the present invention is characterized in that the agent (a) comprises at least one coloring compound (a2) selected from the group consisting of anionic direct dyes, nonionic direct dyes and cationic direct dyes.

[0091] Suitable cationic direct dyes include Basic Blue 7, Basic Blue 26, HC Blue 16, Basic Violet 2, 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.

[0092] As non-ionic direct dyes, non-ionic nitro and quinone dyes and natural azo dyes can be used. Suitable non-ionic direct dyes are those described by 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, known compounds of Disperse Black 9, and 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.

[0093] In the process of the research leading to the present invention, it has been found that a dyeing having good color strength and fastness can be produced using an agent (a) containing at least one anionic direct dye (a2).

[0094] Accordingly, in a further embodiment, the method of the present invention is characterized in that the agent (a) contains at least one anionic direct dye.

[0095] Anionic direct dyes are also called acid dyes. Acid dyes are direct dyes having at least one carboxylic acid group (-COOH) and / or at least one sulfonic acid group (-SO3H). Depending on the pH value, the protonated forms (-COOH, -SO3H) of the carboxylic acid group or sulfonic acid group exhibit an equilibrium relationship with their deprotonated forms (-COO - , -SO3 - existence). The proportion of the protonated form increases with a decrease in pH. When using the direct dye as its salt, the carboxylic acid group or sulfonic acid group exists in the deprotonated form and is neutralized with the corresponding stoichiometrically equivalent cation to maintain electrical neutrality. The acid dyes of the present invention can also be used in the form of their sodium salts and / or their potassium salts.

[0096] The acid dyes in the meaning of the present invention have a solubility in water at 25°C (760 mmHg) greater than 0.5 g / L and thus are not treated as pigments. Preferably, the acid dyes in the meaning of the present invention have a solubility in water at 25°C (760 mmHg) greater than 1.0 g / L.

[0097] Alkaline earth salts (such as calcium salts and magnesium salts) or aluminum salts of acid dyes often have lower solubility than the corresponding alkali salts. If the solubility of these salts is less than 0.5 g / L (25°C, 760 mmHg), they are not included in the definition of direct dyes.

[0098] The essential characteristic of acid dyes is the ability to form an anionic charge, and the carboxylic acid group or sulfonic acid group causing this is usually bonded to various chromophore systems. Suitable chromophore systems can be found, for example, in the structures of nitrophenylenediamine, nitroaminophenol, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes and / or indophenol dyes.

[0099] In another embodiment, the method for dyeing a keratinous material is characterized in that agent (a) comprises at least one anionic direct dye selected from the group consisting of nitrophenylenediamine, nitroaminophenol, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes and / or indophenol dyes, and the dyes from the above group each have at least one carboxylic acid group (-COOH), sodium carboxylate group (-COONa), potassium carboxylate group (-COOK), sulfonic acid group (-SO3H), sodium sulfonate group (-SO3Na) and / or potassium sulfonate group (-SO3K).

[0100] For example, one or more compounds selected from the following group are included as suitable acid dyes: Acid Yellow 1 (D&C Yellow 7, Citronin A, Ext.D&C Yellow No.7, Japan Yellow 403, CI10316, COLIPA n°B001), Acid Yellow 3 (COLIPA n°54, D&C Yellow N°10, Quinoline Yellow, E104, Food Yellow 13), Acid Yellow 9 (CI13015), Acid Yellow 17 (CI18965), Acid Yellow 23 (COLIPA n°29, Covacap Jaune W1100(LCW), Sicovit Tartrazine 85 E102(BASF), Tartrazine, Food Yellow 4, Japan Yellow 4, FD&C Yellow No.5), Acid Yellow 36 (CI13065), Acid Yellow 121 (CI18690), Acid Orange 6 (CI14270), Acid Orange 7 (2-Naphthol orange, Orange II, CI15510, D&C Orange 4, COLIPA n°015), Acid Orange 10 (C.I.16230; Orange G sodium salt), Acid Orange 11 (CI45370), Acid Orange 15 (CI50120), Acid Orange 20 (CI14600), Acid Orange 24 (BROWN 1; CI20170; KATSU201; sodium salt free; Brown No.201; RESORCIN BROWN; ACID ORANGE 24; Japan Brown 201; D&C Brown No.1), Acid Red 14 (C.I.14720), Acid Red 18 (E124, Red18; CI16255), Acid Red 27 (E123, CI16185, C-Rot46, Real red D, FD&C Red Nr.2, Food Red 9, Naphthol red S), Acid Red 33 (Red33, Fuchsia Red, D&C Red33, CI17200), Acid Red 35 (CI C.I.18065), Acid Red 51 (CI 45430, Pyrosin B, Tetraiodfluorescein, Eosin J, Iodeosin), Acid Red 52 (CI 45100, Food Red 106, Solar Rhodamine B, Acid Rhodamine B, Red n°106 Pontacyl Brilliant Pink), Acid Red 73 (CI 27290), Acid Red 87 (Eosin, CI 45380), Acid Red 92 (COLIPA n°53, CI 45410), Acid Red 95 (CI 45425, Erythtosine, Simacid Erythrosine Y), Acid Red 184 (CI 15685), Acid Red 195, Acid Violet 43 (Jarocol Violet 43, Ext.D&C Violet n°2, C.I. 60730, COLIPA n°063), Acid Violet 49 (CI 42640), Acid Violet 50 (CI 50325), Acid Blue 1 (Patent Blue, CI 42045), Acid Blue 3 (Patent Blue V, CI 42051), Acid Blue 7 (CI 42080), Acid Blue 104 (CI 42735), Acid Blue 9 (E133, Patent blue AE, Amido blue AE, Erioglaucin A, CI 42090, C.I.

[0101] For example, the water solubility of an anionic direct dye can be measured by the following method. Introduce 0.1 g of the anionic direct dye into a beaker. Add a magnetic stirring bar. Then add 100 mL of water. Heat this mixture to 25 °C while stirring with a magnetic stirrer. Stir for 60 minutes. Then visually evaluate the aqueous mixture. If undissolved residue is still present, increase the amount of water, for example in 10 mL increments. Add water until the amount of dye used is completely dissolved. If the dye - water mixture cannot be visually evaluated due to the high strength of the dye, filter the mixture. If undissolved dye remains on the filter paper, repeat the solubility test using more water. When 0.1 g of an anionic direct dye dissolves in 100 mL of water at 25 °C, the solubility of that dye is 1.0 g / L.

[0102] Acid Yellow 1 is called disodium 8 - hydroxy - 5,7 - dinitro - 2 - naphthalenesulfonate and has a solubility in water of at least 40 g / L (25 °C). Acid Yellow 3 is a mixture of the sodium salts of the monosulfonic and disulfonic acids of 2 - (2 - quinolyl) - 1H - inden - 1,3(2H) - dione and has a solubility in water of 20 g / L (25 °C). Acid Yellow 9 is the disodium salt of 8 - hydroxy - 5,7 - dinitro - 2 - naphthalenesulfonic acid and its solubility in water is greater than 40 g / L (25 °C). Acid Yellow 23 is the trisodium salt of 4,5-dihydro-5-oxo-1-(4-sulfophenyl)-4-((4-sulfophenyl)azo)-1H-pyrazole-3-carboxylic acid and is highly soluble in water at 25°C. Acid Orange 7 is the sodium salt of 4-[(2-hydroxy-1-naphthyl)azo]benzenesulfonate. Its solubility in water is greater than 7 g / L (25°C). Acid Red 18 is the trisodium salt of 7-hydroxy-8-[(E)-(4-sulfonato-1-naphthyl)diazenyl)]-1,3-naphthalenedisulfonate and has extremely high water solubility greater than 20% by weight. Acid Red 33 is the disodium salt of 5-amino-4-hydroxy-3-(phenylazo)-naphthalene-2,7-disulfonate and its solubility in water is 2.5 g / L (25°C).

[0103] Accordingly, in another embodiment, the method according to the present invention is characterized in that the agent (b) comprises at least one direct dye (a2) 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 27, Acid Red 33, Acid Red 35, Acid Red 51, Acid Red 52, Acid Red 73, Acid Red 87, Acid Red 92, Acid Red 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.

[0104] The direct dyes above 1 can be used in various amounts in agent (a) according to the desired color intensity. Particularly satisfactory results were obtained when agent (a) contained one or more direct dyes in a total amount of 2.0 to 95.0% by weight, preferably 4.0 to 70.0% by weight, more preferably 6.0 to 50.0% by weight, and most preferably 8.0 to 30.0% by weight based on the total weight of agent (a).

[0105] Also, agent (a) may contain at least one photochromic dye or thermochromic dye as coloring compound (a2).

[0106] A photochromic dye is a dye whose hue changes reversibly in response to irradiation with UV light (sunlight or black light). In this process, the chemical structure of the dye changes by UV light, and as a result, the absorption behavior (photochromism) of the dye changes.

[0107] A thermochromic dye is a dye whose hue changes reversibly in response to a temperature change. In this process, the chemical structure of the dye changes due to the temperature change, and as a result, the absorption behavior (thermochromism) of the dye changes.

[0108] Agent (a) may contain one or more photochromic dyes in a total amount of 2.0 to 95.0% by weight, preferably 4.0 to 70.0% by weight, more preferably 6.0 to 50.0% by weight, and most preferably 8.0 to 30.0% by weight based on the total weight of agent (a).

[0109] Agent (a) may contain one or more thermochromic dyes in a total amount of 2.0 to 95.0% by weight, preferably 4.0 to 70.0% by weight, more preferably 6.0 to 50.0% by weight, and most preferably 8.0 to 30.0% by weight based on the total weight of agent (a).

[0110] <Solvent (a3) in agent (a)> The use of the solvent (a3) has continued to yield particularly satisfactory results. Therefore, agent (a) in the present invention may further contain at least one solvent as optional component (a3).

[0111] Suitable solvents (a3) 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, isopropanol, diethylene glycol monoethyl ether, glycerol, phenoxyethanol and benzyl alcohol. The use of 1,2 - propylene glycol is particularly preferred.

[0112] In another particularly preferred embodiment, the method of the present invention is characterized in that the agent (a) comprises at least one solvent (a3) 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 including 1,2 - propylene glycol.

[0113] 1,2 - propylene glycol is also referred to as 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. Glycerol is also known as 1,2,3 - propanetriol and has CAS number 56 - 81 - 5. Phenoxyethanol has CAS number 122 - 99 - 6.

[0114] All of these solvents are commercially available from various chemical suppliers such as Aldrich or Fluka.

[0115] By using the above solvent in an appropriate amount, a particularly stable agent (a) can be obtained, which can be mixed with agent (b) particularly rapidly and uniformly. Further, when an appropriate and preferred solvent (a3) is used, or when 1,2-propylene glycol is used, a coloring result with a very high color intensity in keratinous substances is obtained.

[0116] In a further preferred embodiment, the method of the present invention is characterized in that agent (a) contains one or more solvents (a3) in a total amount of 1.0 to 95.0% by weight, preferably 20.0 to 90.0% by weight, more preferably 40.0 to 85.0% by weight, and particularly preferably 60.0 to 85.0% by weight, based on the total weight of agent (a).

[0117] In another very particularly preferred embodiment, the method of the present invention is characterized in that agent (a) contains 1,2-propylene glycol in a total amount of 1.0 to 95.0% by weight, preferably 20.0 to 90.0% by weight, more preferably 40.0 to 85.0% by weight, and particularly preferably 60.0 to 85.0% by weight, based on the total weight of agent (a).

[0118] <Packaging of agent (a)> As described above, agent (a) is preferably a concentrate or premix mainly containing components (a1) and (a2) which are essential for the present invention. Preferably, agent (a) contains at least one solvent as a third optional component (a3).

[0119] Without being limited to this theory, it is considered that the coloring compound (a2) (especially when this is a pigment) and the amino-functionalized silicone polymer (a1) can interact with each other. This interaction mainly seems to occur in an aqueous environment or an environment containing water. One hypothesis is that an interaction occurs between each surface of the pigment and the amino groups of the silicone polymer, whereby water can act as a proton donor or a proton acceptor.

[0120] This assumption is supported by the finding that in preparations containing, in addition to the amino silicone (a1) and the pigment (a2), the components of the carrier preparation, namely water (b1) and the fatty component (b2), at a higher concentration, deposition of the resinous substance can be observed after several days. When this preparation was used for the staining test after storage for several days, only staining with a very low color intensity was obtained.

[0121] Surprisingly, the corresponding anhydrous agent (a) formulated in the form of a premix or concentrate and not containing water (b1) and the fatty component (b2) remained stable without aggregation or deposition of resin. Thereby, it has been found that it is particularly preferred to select a correspondingly low water content in the agent (a). With an agent (a) having a maximum water content of 10% by weight, a very strong coloring result was obtained. However, when the water content in the agent (a) was lowered to a maximum value of 5.0% by weight or less, more preferably 2.5% by weight or less, and most preferably 1.0% by weight or less, the storage stability and the staining performance can be further improved. In this specification, the water content is based on the total weight of the agent (a).

[0122] Even more specifically, in a very particularly preferred embodiment, the method of the present invention is characterized in that the agent (a) contains less than 10.0% by weight, preferably less than 5.0% by weight, more preferably less than 2.5% by weight, and particularly preferably less than 1.0% by weight of water, based on the total weight of the agent (a).

[0123] In other words, even more specifically, in a very particularly preferred embodiment, the method of the present 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, and particularly preferably 0 to 1.0% by weight, based on the total weight of the agent (a).

[0124] The premix or agent (a) in the present invention contains, as main components, the above components (a1), (a2) and optionally (a3), and these are particularly preferably used in the agent (a) in a corresponding excess amount.

[0125] As a rule, the premix or concentrate can, if necessary, also contain other components different from components (a1), (a2), and optionally (a3). These other components can be, for example, preservatives, fragrances or thickeners. However, particularly good storage stability could be obtained when a substantial proportion of agent (a) was composed of components (a1), (a2) and optional (a3). Therefore, it has been found that it is particularly advantageous with respect to the object of the present invention when the combined weight fraction of components (a1), (a2) and (a3) is at least 70.0% by weight, preferably at least 80.0% by weight, more preferably at least 90.0% by weight, very particularly preferably at least 95.0% by weight, based on the total weight of agent (a).

[0126] In other words, it was very particularly advantageous only when agent (a) contained further components other than components (a1), (a2) and (a3) in a weight fraction of at most 30.0% by weight, preferably at most 20.0% by weight, very particularly preferably only 10.0% by weight.

[0127] Even more clearly in a very particularly preferred embodiment, the method of the present invention is characterized in that the combined weight fraction of components (a1), (a2) and (a3) is at least 70.0% by weight, preferably at least 80.0% by weight, more preferably at least 90.0% by weight, very particularly preferably at least 98.0% by weight, based on the total weight of agent (a).

[0128] If the solvent (a3) is not contained in agent (a) as an optional component, only components (a1) and (a2) are present as the main components of agent (a). In this embodiment, it is advantageous only when agent (a) contains further components different from components (a1) and (a2) in a weight fraction of at most 30.0% by weight, preferably at most 20.0% by weight, very preferably only 10.0% by weight.

[0129] In a further particularly preferred embodiment, the method of the present invention is characterized in that the combined weight fraction of components (a1) and (a2) is at least 70.0% by weight, preferably at least 80.0% by weight, more preferably at least 90.0% by weight, and very particularly preferably at least 95.0% by weight, based on the total weight of agent (a).

[0130] <Agent (b)> In step (2) of the method of the present invention, agent (b) is provided. For example, agent (b) can be present in a packaging unit or container, thereby enabling access by the user. The container can be, for example, a sachet, bottle, can, jar or other container suitable for cosmetic preparations.

[0131] Agent (b) is an actual colorant and is characterized by the content of water (b1), a fatty component (b2), and at least one coloring compound (b3).

[0132] When agents (a) and (b) are mixed, preferably a high-concentration and low-water concentrate of agent (a) is mixed with the actual colorant (b). During this mixing, the amino silicone (a1) comes into contact with the pigment (b3) incorporated in the emulsion, so the interaction between the aforementioned amino silicone (a1) and pigment (b3) only begins from the moment of this mixing. Surprisingly, this type of finish in the dyeing process results in a strong and wash-fast dyeing result, and it has also been observed that it is further characterized by particularly good homogeneity.

[0133] <Agent (b)> In step (2) of the method of the present invention, agent (b) is provided. For example, agent (b) can be present in a packaging unit or container, thereby enabling access by the user. The container can be, for example, a sachet, bottle, can, jar or other container suitable for cosmetic preparations.

[0134] Agent (b) is a carrier preparation or a base preparation and is characterized by an accurately adjusted water content (b1) and a content of fatty components (b2).

[0135] By mixing agent (a) and agent (b), a premix with preferably high concentration and low water content is converted into an applicable form and can then be applied to keratinous substances.

[0136] <Water content in agent (b)> Agent (b) is characterized by being either water-free, i.e., having a water content of 0% by weight based on the total weight of agent (b), or otherwise having a low water content of at most 50% by weight.

[0137] In the process of the research leading to the present invention, it has been found that the water content of agent (b) has a considerable influence on the feel of keratinous substances or hair.

[0138] For example, when a preparation with a very high water content in addition to the fatty component (b2) was germ-mixed with agent (a) of the present invention, a dye with high color intensity could be obtained, but the feel of the keratin fibers dyed thereby was inferior. In this specification, a low grip feeling should be understood to mean that the feel of keratin fibers, especially hair, is poor, rough and hard, and not manageable by hand.

[0139] On the other hand, when agent (a) of the present invention was mixed with agent (b) of the present invention, the dyed hair felt much softer, more comfortable and less dull.

[0140] Therefore, in order to optimize both the color intensity and the feel of the dyed keratin fibers, agent (b) is very preferably adjusted to a specific water content. The best results were obtained when agent (b) contained 0 to 45% by weight, preferably 5 to 40% by weight, more preferably 10 to 35% by weight, and very particularly preferably 15 to 35% by weight of water (b1) based on the total weight of the agent (b).

[0141] Even more specifically, in a very particularly preferred embodiment, the method of the present invention is characterized in that agent (b) contains 0 to 45% by weight, preferably 5 to 40% by weight, more preferably 10 to 35% by weight, and very particularly preferably 15 to 35% by weight of water (b1) based on the total weight of agent (b).

[0142] <The fat component (b2) in agent (b)> A further characteristic of agent (b) is the content of at least one fat component (b2). It has been found that when using at least one fat component, agent (b) is in the form of an emulsion, which enables particularly good and rapid mixing with agent (a).

[0143] The fat component is a hydrophobic substance that can form an emulsion in the presence of water and form a micelle system.

[0144] For the purposes of the present invention, "fat component" means an organic compound having a solubility in water of less than 1% by weight, preferably less than 0.1% by weight, at room temperature (22 °C) and atmospheric pressure (760 mmHg). The definition of the fat component explicitly covers only uncharged (i.e., non-ionic) compounds. The fat component has at least one saturated or unsaturated alkyl group having at least 12 carbon atoms. The molecular weight of the fat component is at most 5000 g / mol, preferably at most 2500 g / mol, and particularly preferably at most 1000 g / mol. The fat component is neither a polyoxyalkylated compound nor a polyglycerylated compound.

[0145] Very preferably, the fat component (b2) contained in agent (b) is an ester oil, C 12 -C 30 fatty alcohol, C 12 -C 30 triglyceride fatty acid, C 12 -C 30 monoglyceride fatty acid, C 12 -C 30It is selected from the group consisting of fatty acid diglycerides and / or hydrocarbons. In the context of the present invention, only non-ionic substances are clearly considered as fatty components. Charged compounds such as fatty acids and their salts are not regarded as fatty components.

[0146] In a further preferred embodiment, in the method of the present invention, agent (b) is an ester oil, C 12 -C 30 fatty alcohol, C 12 -C 30 fatty acid triglyceride, C 12 -C 30 fatty acid monoglyceride, C 12 -C 30 characterized by comprising one or more fatty components (b2) from the group consisting of fatty acid diglycerides and / or hydrocarbons.

[0147] According to the present invention, the ester oil is an ester of C6-C 30 alkanecarboxylic acid and C2-C30 aliphatic alcohol. The aliphatic C2-C 30 monoalcohol is used for esterification to the ester oil. The aliphatic C2-C 30 monoalcohol is a compound having only one hydroxyl group.

[0148] In another very particularly preferred embodiment, in the method of the present invention, agent (b) is characterized by comprising at least one fatty component (b2) from the group of esters of C6-C 30 alkanecarboxylic acid and aliphatic C2-C 30 monoalcohol.

[0160] Furthermore, as a more preferred fatty component (b2), the agent (b) may contain at least one C 12 -C 30 fatty acid triglyceride, C 12 -C 30 fatty acid monoglyceride and / or C 12 -C 30 fatty acid diglyceride.

In the formation of the ester, both structurally identical and structurally different fatty acids within the triglyceride molecule can be involved.

[0161] In the present invention, the fatty acid is understood to be a saturated or unsaturated, unbranched or branched, unsubstituted or substituted C 12 -C 30 carboxylic acid. The unsaturated fatty acid may be monounsaturated or polyunsaturated. In the case of an unsaturated fatty acid, its C-C double bond may have a cis structure or a trans structure.

Fatty acid triglycerides present in soybean oil, peanut oil, olive oil, sunflower oil, macadamia nut oil, moringa oil, apricot kernel oil, marula oil and / or optionally hydrogenated castor oil, or mixtures thereof, are particularly suitable for use in the formulations of the present invention.

[0164] C 12 -C 30Fatty acid monoglycerides are understood to be monoesters of the trivalent alcohol glycerol and one equivalent of fatty acid. Either the central hydroxy group of glycerol or the terminal hydroxy group of glycerol can be esterified by the fatty acid.

[0166] C 12 -C 30 Fatty acid diglycerides are diesters of the trivalent alcohol glycerol and two equivalents of fatty acid. Here, the central hydroxy group of glycerol and the hydroxy group at one end can be esterified with two equivalents of fatty acid, or the hydroxy groups at both ends of glycerol can each be esterified with one fatty acid. Glycerol can be esterified with two structurally identical fatty acids or two structurally different fatty acids.

[0167] At least one of the ester groups is particularly suitable for a fatty acid diglyceride formed from glycerol and a fatty acid selected from dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z)-6-octadecenoic acid], palmitoleic acid [(9Z)-hexadec-9-enoic acid], oleic acid [(9Z)-octadec-9-enoic acid], elaidic acid [(9E)-octadec-9-enoic acid], erucic acid [(13Z)-docos-13-enoic acid], linoleic acid [(9Z,12Z)-octadeca-9,12-dienoic acid], linolenic acid [(9Z,12Z,15Z)-octadeca-9,12,15-trienonic acid, elaeostearic acid [(9Z,11E,13E)-octadeca-9,11,3-trienonic acid], arachidonic acid [(5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoic acid], and / or nervonic acid [(15Z)-tetracos-15-enoic acid].

The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses having 5 or 6 carbon atoms, preferably glucose. Thus, preferred alkyl and / or alkenyl oligoglycosides are alkyl and / or alkenyl oligoglucosides. The subscript p in the general formula (Tnio-2) represents the degree of oligomerization (DP), i.e., the distribution of monoglycosides and oligoglycosides, and represents a number from 1 to 10. p must always be an integer in an individual molecule and can take values of p = 1 to 6, but the value p of a specific alkyl oligoglycoside is an analytically determined arithmetic quantity and usually represents a decimal. Preferably, alkyl and / or alkenyl oligoglycosides having an average degree of oligomerization p of 1.1 to 3.0 are used. From the perspective of application technology, those alkyl and / or alkenyl oligoglycosides preferably have a degree of oligomerization of less than 1.7 and between 1.2 and 1.4. The alkyl or alkenyl group R 4 can be derived from primary alcohols containing 4 to 11 carbon atoms, preferably 8 to 10 carbon atoms. Typical examples are butanol, capron alcohol, capryl alcohol, capric alcohol and undecyl alcohol, and industrial mixtures thereof, such as those obtained upon hydrogenation of industrial fatty acid methyl esters or hydrogenation of aldehydes from the oxo synthesis of olefins. Alkyl oligoglucosides with a chain length of C8-C 10 (DP = 1 to 3) are preferred. This is obtained as a preliminary stage in the fractional distillation of technical C8-C 18 coconut fatty alcohol and may be contaminated with less than 6% by weight of C 12 alcohol and alkyl oligoglucosides based on technical C 9 / 11 oxo alcohol (DP = 1 to 3).

Preferably, the fatty acid N-alkyl polyhydroxyalkylamide is derived from a reducing sugar having 5 or 6 carbon atoms, especially glucose. Accordingly, a preferred fatty acid N-alkyl polyhydroxyalkylamide is of the formula (Tnio-4): TIFF0007717056000018.tif14127 is a fatty acid N-alkyl glucamide represented by)

[0184] Preferably, the glucamide represented by formula (Tnio-4) is used as a fatty acid-N-alkyl polyhydroxyalkylamide, wherein R 8 represents hydrogen or an alkyl group, and R 7 CO represents an acyl group of 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, gadoleic acid, behenic acid or erucic acid or an industrial mixture thereof. Particularly preferred is a fatty acid N-alkyl glucamide represented by formula (Tnio-4), which is obtained by reductively aminating glucose with methylamine and then acylating with lauric acid, C12 / 14 coconut fatty acid or a corresponding derivative. Also, polyhydroxyalkylamides can be derived from maltose and palatinose.

[0185] The sugar surfactant may preferably be present in the agent used according to the present invention in an amount of 0.1 to 20% by weight, based on the total amount of the agent. An amount of 0.5 to 15% by weight is preferred, and an amount of 0.5 to 7.5% by weight is particularly preferred.

[0186] Other typical examples of nonionic surfactants are fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, mixed ethers or mixed formals, protein hydrolysates (especially plant products derived from wheat) and polysorbates.

[0187] Alkylene oxide adducts of saturated straight-chain fatty alcohols and fatty acids containing 2 to 30 moles of ethylene oxide per mole of the respective fatty alcohol or fatty acid, and sugar surfactants, have been found to be preferred nonionic surfactants. When an ethoxylated glycerol fatty acid ester is included as the nonionic surfactant, a formulation with excellent properties can also be obtained.

[0188] These linkages are identified by the following parameters. The alkyl group R contains from 6 to 22 carbon atoms and may be either straight-chain or branched-chain. Primary straight-chain and 2-methyl-branched aliphatic groups are preferred. Such alkyl groups are, for example, 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. Particularly preferred are 1-octyl, 1-decyl, 1-lauryl, 1-myristyl. When using so-called "oxo alcohols" as starting materials, compounds having an odd number of carbon atoms in the alkyl chain are advantageous.

[0189] Compounds having an alkyl group used as a surfactant can each be a homogeneous substance. However, in the production of these substances, it is usually preferred to start from conventional plant or animal raw materials, so a mixture of substances with different alkyl chain lengths is obtained depending on each raw material.

[0190] Regarding surfactants that are addition products of ethylene and / or propylene oxide to fatty alcohols or derivatives of these addition products, both products having a "normal" homolog distribution and products having a narrow homolog distribution can be used. The "normal" homolog distribution means a mixture of homologs obtained by the reaction of a fatty alcohol and an alkylene oxide using an alkali metal, an alkali metal hydroxide, or an alkali metal alcoholate as a catalyst. On the other hand, for example, when hydrotalcite, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts, a narrow homolog distribution is obtained. The use of products with a narrow homolog distribution may be preferred in some cases.

[0221] The selection of these other substances is made by those skilled in the art according to the desired properties of the agent. The other optional components and the amounts of such components used are specified in the relevant manuals known to those skilled in the art. The additional active ingredients and auxiliaries are preferably used in the preparations according to the invention in amounts of 0.0001 to 25% by weight, respectively, and 0.0005 to 15% by weight, respectively, based on the total weight of each agent.

[0222] However, as described above, the agent (a) preferably consists of the component (a1), the component (a2), and optionally the component (a3). If the agent (a) is to contain any of the above other optional components, it is particularly preferred that these are used only in small amounts in the agent (a).

[0223] <Preparation of the application mixture by mixing agents (a) and (b)> In step (3) of the method of the present invention, the ready-to-use mixture is prepared by mixing the agent (a) and the agent (b). In other words, at this process stage, the premix or concentrate (a), i.e., a very high concentration mixture of preferably low water and the aminosilicone (a1), the coloring compound (a2) and the optional solvent (a3), is mixed with the cosmetic carrier preparation (b) containing the low water content (b1) and the fatty component (b2).

[0224] In principle, different amounts of the agent (a) can be mixed with the agent (b), so a mixing ratio (a) / (b) of 1:200 to 200:1 is conceivable.

[0225] However, since the premix (a) is preferably a concentrate, it has been found that it is particularly preferred to use a small amount of the agent (a) and dilute these with a relatively large amount of the agent (b).

[0226] It is particularly preferred when the application mixture is prepared by mixing the agent (a) and the agent (b) in a quantitative ratio (a) / (b) of 1:2 to 1:200, preferably 1:5 to 1:100, more preferably 1:5 to 1:40, and most preferably 1:15 to 1:20.

[0248] <Exposure of the application mixture to the keratinous substance> In step (5) of the method of the present invention, the application mixture can act on the keratinous substance after its application. In the present invention, for example, various exposure times from 30 seconds to 60 minutes are conceivable.

[0249] However, the main advantage of the dyeing method according to the present invention is that a strong coloring result can be achieved even in a short time after a short exposure time. For this reason, it is advantageous if the application mixture remains on the keratinous substance for a relatively short time, from 30 seconds to 15 minutes, preferably from 30 seconds to 10 minutes, particularly preferably from 1 to 5 minutes, after its application.

[0258] For example, if agent (a) and agent (b) are provided to the user in a multi-component packaging unit, both agents are provided simultaneously and the user decides which agent to remove first from the packaging.

[0259] The preparation of the application mixture by mixing agent (a) and agent (b) in step (3) can only be carried out after both agent (a) and agent (b) have been provided.

[0260] The application of the application mixture in step (4) can be carried out only after its preparation in step (3).

[0261] Similarly, the exposing of the application mixture in step (5) can be performed after applying the application mixture to the keratinous material, and the rinsing of the application mixture in step (6) can be performed after applying it in step (5).
