I declare further that to the best of my knowledge and belief the following is a true and correct translation of the above-identified PCT. Declared at Strassen, this 28.11.2007 Pi re K dec-au-err PCT/EP2006/006990 H 06765 METHOD FOR QUICKLY CONCEALING THE ROOTS OF HAIR THAT HAVE GROWN AFTER THE HAIR HAS BEEN DYED [0002] The present invention relates to a process for quickly concealing the roots of hair that have grown after the hair has been dyed, in which a hair root dye with a defined viscosity is left for a defined period of time on the hair roots and rinsed off again. In addition, the use of the hair root dye for selectively dyeing hair roots, together with a kit, comprising the hair root dye, application aids and optionally a mixing bowl is the subject matter of the invention. [0003] Nowadays, human hair is treated in a variety of ways with hair cosmetic preparations. They include, for example, the cleaning of hair with shampoos, care and regeneration with rinses and cures as well as bleaching, dyeing and styling the hair with colorants, toners, permanent wave lotions and styling preparations. Among these, agents for changing or nuancing the color of hair play a prominent role. From the viewpoint of the lighteners, which produce an oxidative lightening of the hair by degrading the natural hair colorants, there exist essentially four important types of hair dyes in the field of hair dyeing. [0004] The so-called oxidation dyes are used for long-lasting, intensive colorations with corresponding authentic characteristics. Such hair root dyes usually comprise oxidation dye precursors, "developer components" and "coupler components". Under the influence of oxidizing agents or from atmospheric oxygen, the developer components form the actual colorants among each other or by coupling with one or more coupler components. Indeed, the oxidation dyes are characterized by excellent, long lasting coloration results. However, for colorations with a natural appearance, normally a mixture of a large number of oxidation dye precursors must be employed; in many cases, further substantive dyes are used for nuancing. [0005] Normally, primary aromatic amines with an additional free or substituted hydroxyl or amino group in the para or ortho position, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives as well as H 06765 2,4,5,6-tetraaminopyrimidine and derivatives thereof are employed as the developer components. [0006] Specific exemplary representatives are p-phenylenediamine, p toluylenediamine, 2,4,5,6-tetraaminopyrimidine, p-aminophenol, N,N-bis(2 hydroxyethyl)-p-phenylenediamine, 2-(2,5-diaminophenyl)-ethanol, 2-(2,5 diaminophenoxy)-ethanol, 1-phenyl-3-carboxyamido-4-amino-pyrazolone-5, 4 amino-3-methylphenol, 2-aminomethyl-4-aminophenol, 2-hydroxy-4,5,6 triaminopyrimidine, 2,4-dihydroxy-5,6-diaminopyrimidine, 2,5,6-triamino-4 hydroxypyrimidine and 1,3-N,N'-bis(2-hydroxyethyl)-N,N'-bis(4-aminophenyl) diaminopropane-2-ol. [0007] m-Phenylenediamine derivatives, naphthols, resorcinol and resorcinol derivatives, pyrazolones and m-aminophenols are generally used as the coupling components. Particularly suitable coupling substances are 1-naphthol, 1,5-dihydroxynaphthalene, 2,7-dihydroxynaphthalene and 1,7 dihydroxynaphthalene, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resorcinol monomethyl ether, m-phenylenediamine, 1 -phenyl-3 methylpyrazolone-5, 2,4-dichloro-3-aminophenol, 1,3-bis(2,4 diaminophenoxy)propane, 2-chlororesorcinol, 4-chlororesorcinol, 2-chloro-6 methyl-3-aminophenol, 2-methylresorcinol, 5-methylresorcinol and 2-methyl-4 chloro-5-aminophenol. [0008] For temporary colorations, usually colorants or toners are used that comprise "substantives" as the coloring component. These are dye molecules that are directly absorbed onto the hair and do not require any oxidative process to develop the color. These dyes include, for example, Henna that was already known in antiquity for dyeing skin and hair. In general, these dyes are significantly more sensitive to shampooing than are oxidative dyes, with the result that many unwanted nuance shifts or even a visible "decolorization" occur. [0009] Finally, another dyeing method has attracted lots of interest. In this method, precursors of the natural hair dye melanin are applied onto the hair; in the course of oxidative processes they then form analogs to natural colorants in 2 H 06765 the hair. This type of product with 5,6-dihydroxyindoline as the dye precursor was described in EP-B1-530 229. By using, especially repeated use, of agents with 5,6-dihydroxyindoline it is possible to restore the natural hair color to people with gray hair. In this way the coloration can take place with atmospheric oxygen as the sole oxidizing agent, with the result that no recourse is needed to other oxidizing agents. The indoline can be employed as the sole dye precursor for people with naturally medium blond to brown hair. On the other hand, for use with people with naturally red and especially dark to black hair, satisfactory results can frequently only be obtained when additional dye components are used as well, in particular specific oxidation dyestuff precursors. [00101 One possibility of dyeing keratin-containing fibers is offered by the use of dyes which comprise a combination of component A compounds that comprise a reactive carbonyl group with component B compounds selected from (a) CH-acidic compounds and (b) compounds containing primary or secondary amino groups or hydroxyl groups, selected from primary or secondary aromatic amines, nitrogen containing heterocyclic compounds and aromatic hydroxy compounds. The corresponding dyeing method (hereinafter called oxo dyeing) is described for example in the publications WO-A1-99/18916, WO-A1-00/38638, WO-Al 01/34106 and WO-A1-01/47483. The resulting colorations possess to some extent genuine colors on the keratinic fibers that are comparable with those made by oxidation dyeing. The nuance spectrum that is obtainable with the gentle oxo dyeing is very broad and the resulting color often exhibits an acceptable brilliance and depth of color. The previously mentioned components A and B, hereinafter called oxo dye precursors, are generally not dyes themselves, and therefore are not all suitable per se for dyeing keratinic fibers. In combination, they form dyes in a non-oxidative process. However, among the compounds of components B, suitable oxidation dye precursors of the developer type and/or coupler type also find use with or without added oxidizing agents. In this way the oxo dyeing method can be directly combined with the oxidative dye system. 3 H 06765 [0011] Hair coloration with permanent or semi-permanent dyes has the disadvantage that after some time the hair coloration grows out. There then results a zone of un-dyed hair at the hair roots; this is normally eliminated by dyeing the complete head of hair. With this method, however, the already dyed hair is treated again with the hair-root dye. The lengths of hair that were dyed and thereby stressed prior to the treatment are once more unnecessarily stressed by the repeated dyeing. [0012] When concealing the un-dyed hair roots, care must be taken to ensure that the resulting coloration is uniform. After concealment, the visible boundary before dyeing between already dyed hair and un-dyed hair should in the best case be no longer discernable. [0013] Dyeing the hair roots with a tinting agent based exclusively on substantive dyes does not offer a long-lasting solution for concealing hair roots because only a temporary coloration is obtained. [0014] In EP-B1-624 362 it is suggested to protect the already heavily stressed lengths of hair by dyeing the hair roots in a two-step dyeing process with an alkaline oxidative dyestuff and the total length of hair with an acidic oxidative dyestuff. However, this working method means that the already damaged length of hair comes into contact again with the oxidizing agent in each dyeing step. [0015] In WO-A1-01/26616 is described a two step process for dyeing hair, in which the un-dyed hair roots are firstly colored with a commercial oxidative hair dye and the lengths of hair are dyed with a hair root dye based for example on oxo dye precursors. The contact time of the oxidative hair dye on the lengths of hair is more than 20 minutes for an effective dyeing. [0016] The known methods provide a time-consuming opportunity for dyeing the hair roots. Accordingly, the object of the present invention is to provide a rapid method for concealing the newly grown hair roots, which offers an effective and uniform coloration after a short application time, without subjecting the already dyed lengths of hair to a fresh coloration. 4 H 06765 [0017] Surprisingly, it has been found that un-dyed parts of the hair roots can be quickly and selectively matched to the shade of color of the growing dyed hair when the applied hair root dye has a defined viscosity. [0018] Accordingly, a first subject matter of the invention is a method for selectively dyeing un-dyed hair roots of hair, which have a dyed hair color in the length of the hair, in which in the first step A a hair root dye, which comprises at least one chromophoric component in a cosmetic carrier, is applied to the un-dyed roots and is rinsed off after a contact time Z1, and optionally in a step B all the fibers are then treated with a hair conditioner, wherein the hair root dye has a viscosity at 20 0 C of 2000 to no greater than 27000 mPa s (Brookfield rotation viscosimeter, Type RTV, spindle 5, 2 rpm), and the contact time Z1 does not exceed 20 minutes. [0019] In the context of this application, keratin-containing fibers are understood to mean furs, wool, feathers and particularly human hair. The keratin containing fibers to be treated according to the inventive method have a partial hair coloration and possess two zones. Examples of this type of keratin containing fibers are found in the case of a grown out hair coloration. The un-dyed hair roots (zone 1) consist of newly grown, almost unstressed hair. The dyed lengths of hair (zone 2) were dyed with a preferably permanent or semi permanent hair color. The lengths of hair had been dyed for some time, preferably at least 1 week, before carrying out the inventive method for dyeing, particularly an oxidative dyeing of the (preferably whole) hair. [0020] In the scope of the inventive method, the dyed lengths of hair are neither treated with the hair root dye nor with any other hair dye. Specifically, only the un-dyed hair roots are dyed with the cited hair root dye. For this purpose the hair root dye has to be applied from the hair roots up to the boundary with the dyed lengths of hair. It is very difficult to avoid that minimal areas of the previously dyed hair likewise come into contact with the hair root dye. These minimal areas should preferably account for less than 20 % of the dyed length of hair, but preferably not more than 1 cm. 5 H 06765 [0021] An aerosol spray, a pumpable container, a brush or a paintbrush, especially a paintbrush, is used in the inventive method. Examples of suitable paintbrushes for the application are known from the patent US-A-6 092 535 or from the hairdresser's text book "Chemie in der modernen Fris6rpraxis" by H. Miller et al., Verlag Handwerk und Technik, 2nd improved edition, 1971, p.106, to which explicit reference is made to each in their entirety. [0022] If the viscosity of the hair root dye at 20 *C is from 2000 to maximum 10000 mPa s, especially from 4000 to maximum 10000 mPa s (Brookfield Rotation viscosimeter, Type RTV, spindle 5, 2 rpm), then it can be preferred to package this hair root composition in an aerosol container together with a propellant, or in a pumpable container. In the scope of this embodiment, the container can have a plurality of chambers, from which the various compositions are discharged and are mixed together to form the hair root dye before leaving the container. During the application step the spraying head of the aerosol or pumping container is held as close as possible, preferably at a distance of not more than ca. 2 cm from the hair roots being treated, and the hair root dye is sprayed or squirted on. However, an applicator in the form of a brush or a paintbrush can also be affixed to the spraying head, such that on leaving said container the hair root dye directly reaches the applicator and is therefore ready to be applied. [0023] Fundamentally, a person in addition to the subject is not required for carrying out the inventive method. The provision of the inventive method and the corresponding packaging unit of the second subject matter of the invention allows a hair root dye to be offered to the individual user for home use. [0024] In a preferred embodiment of the inventive method, the hair is combed smooth prior to applying the hair root dye. The hair is then parted with a comb. The paintbrush is then used to apply the hair root dye onto the un-dyed hair roots along the parting from the scalp to the boundary of the dyed length of hair. After completing the application, the hair is again parted and the application process is implemented in the same way as described above. Here, care must be taken to ensure that the hair root dye already present in the hair is 6 H 06765 not combed into the lengths of hair. Using this method the totality of the un dyed hair roots is dyed. [0025] It is also possible to curl the hair as usual and to apply the hair root dye only onto the visible, un-dyed hair roots. With this method the totality of the un dyed hair roots is not dyed, rather only those un-dyed areas are touched up that are visible in the normal hairstyle. [0026] When neither aerosol nor pumpable container is used, then preferably prior to the application the hair root dye is added to a bowl or, when two components have to be mixed before the application, they are mixed in this bowl. The bristles of the paintbrush (about 2/3 of their length) are then dipped into the hair root dye, and then applied to the hair roots preferably as described above. [0027] During the contact time Z1, the hair dye warms up from the ambient temperature to the body temperature. This warming often results in a change or a decrease in viscosity. Accordingly, in the inventive method, those hair root dye compositions are preferably used, which have a stable viscosity when warmed from 20 *C to 45 *C, such that the abovementioned viscosity parameters are also met at the application temperature. It has been shown that the fast root dyeing occurs in the inventive viscosity range. Moreover in this range, the hair roots can be selectively dyed. The hair root dye composition does not run and consequently remains in the zone of the un-dyed hair roots. In this way any re-dyeing of the already dyed lengths of hair is largely prevented. [0028] It is again preferred when the viscosity of the hair root dye composition over the temperature range 20 *C to 45 *C, particularly 20 *C to 40 "C ranges from 2000 to maximum 27000 mPa s, especially from 4000 to maximum 27000 mPa s (Brookfield Rotation viscosimeter, Type RTV, spindle 5, 2 rpm). [0029] An example of a suitable viscosity-stable dye in the form of an oxidation dye is described in the publication WO-Al-03/13450, to which explicit reference is made in its entirety. The 2-component dyes disclosed therein consist of a composition that comprises the chromophoric components and a further composition comprising an oxidizing agent, said composition additionally 7 H 06765 comprising at least one branched (C 6 to C 30 ) fatty acid and/or at least one branched or linear (C 8 to C 30 ) dicarboxylic acid. The publication does not contain any information concerning the viscosity of the dye. [0030] According to the inventive method, the contact time Z1 of the hair root dye preferably ranges from 15 minutes at most, particularly preferably 10 minutes at most. [0031] When the hair root dye of the inventive method is an oxidative hair root dye, it comprises as the chromophoric component at least one developer component and optionally in addition at least one coupler component. Normally, primary aromatic amines with an additional free or substituted hydroxyl or amino group in the para or ortho position, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazole derivatives as well as 2,4,5,6 tetraaminopyrimidine and derivatives thereof are employed as the developer components. [0032] According to the invention, it may be preferred to use a p phenylenediamine derivative or one of its physiologically compatible salts as the developer component. Particular preference is given to p-phenylenediamine derivatives of the formula (El)

[0069] The hair root dyeing compositions of the method according to the invention comprise both the developer components and also the coupler components preferably in an amount of from 0.005 to 10% by weight, preferably from 0.1 to 5% by weight, in each case based on the total hair root dyeing composition. [0070] Here, developer components and coupler components are generally used in approximately molar amounts relative to one another. Although the molar use has also proven to be expedient, a certain excess of individual oxidation dye precursors is not disadvantageous, meaning that developer 21 H 06765 components and coupler components may be present in a molar ratio of from 0: 0.5 to 1: 3, in particular, 1: 1 to 1: 2. [0071] If the hair root dyeing composition of the inventive method is an oxo dye, then it comprises as the chromophoric component i at least one compound that comprises a reactive carbonyl group, in combination with component ii at least one compound selected from (a) CH-acidic compounds and (b) compounds containing primary or secondary amino groups or hydroxyl groups, selected from primary or secondary aromatic amines, nitrogen containing heterocyclic compounds and aromatic hydroxy compounds. [0072] The component i and the component ii are preferably packaged in separate cosmetic compositions 1 and 2 and the actual hair root dye is mixed from these two compositions shortly before application. For the purposes of viscosity stabilization, at least one of the compositions 1 and 2 of this embodiment can additionally comprise at least one branched (C6 to C30) fatty acid and/or at least one branched or linear (C8 to C 30 ) dicarboxylic acid.

The dicarboxylic acid (mixture) that results from the reaction of linoleic acid with acrylic acid has proven to be particularly inventively advantageous as the branched or linear (C8 to C30) dicarboxylic acid. In fact it is a mixture of 8-(2'-carboxy-4'-hexylcyclohex 5'-ene)-1-octanoic acid and 8-(2'-carboxy-4'- hexylcyclohex-5'-ene)-1 -octanic acid. Such compounds are commercially obtainable under the trade names Westvaco Diacid® 1550 and Westvaco Diacid* 1595 (Manufacturer: Westvaco). 22 H 06765 [0074] Compounds according to the invention with a reactive carbonyl group (also termed below, "reactive carbonyl compounds" or component i) have at least one carbonyl group as the reactive group that reacts with the compounds of component ii to form a chemical bond linking the two components.

[0088] The hair root dye compositions can comprise the substantive dyes in an amount of 0.1 to 5% by weight, based on the total hair root dye composition. [0089] In addition, the hair root dye compositions of the inventive method can also comprise naturally occurring dyestuffs such as for example contained in henna red, henna neutral, henna black, camomile leaves, sandalwood, black tea, alder buckthorn bark, sage, logwood, madder root, cashew, cedar and alkanet root. [0090] It is not required that each of the oxidation dyestuff precursors or the substantive dyestuffs be pure compounds. In fact, the inventive hair root dyes, due to the manufacturing processes for the individual dyestuffs, may comprise minor quantities of even more components, in so far as they have no detrimental influence on the coloration result or that they must be excluded on other grounds, e.g. toxicological. [0091] In regard to the useable dyestuffs in the inventive hair root dyes, reference is expressly made to the monograph of Ch. Zviak, The Science of Hair Care, chapter 7 (pages 248-250; substantive dyes) and chapter 8, pages 264-267; oxidation dyestuff precursors), published as volume 7 in the series "Dermatology" (Editor: Ch. Culnan and H. Maibach), Verlag Marcel Dekker Inc., New York, Basel, 1986, as well as the "European Inventory of Cosmetic Raw Materials", published by the European Union, obtainable in disk form from the Bundesverband Deutscher Industrie und Handelsunternehmen fOr Arzneimittel, Reformwaren und K6rperpflegemittel e.V., Mannheim. [0092] Fundamentally, an oxidative dyeing of the hair roots can occur in the presence of oxidation dye precursors with atmospheric oxygen. However, it is preferred to use a chemical oxidizing agent, particularly when a lightening effect of the natural pigments of human hair besides dyeing is desired. This lightening effect may be desired independently of the dyeing method. The presence of oxidation dye precursors is accordingly not a necessary prerequisite for the use 37 H 06765 of oxidizing agents in the hair root dyeing compositions of the method according to the invention. Suitable oxidizing agents are, in particular, hydrogen peroxide and its addition products onto urea, melamine and sodium borate. If the dye precursors and the oxidizing agent are stored separately, then the actual hair root dyeing composition is prepared directly prior to use by mixing. Accordingly, in a preferred embodiment of the inventive method, the hair root dye is mixed prior to application from a composition comprising at least one chromophoric component in a cosmetic carrier, and a further composition comprising at least one oxidizing agent in a cosmetic carrier. [0093] For the purposes of viscosity stabilization, the composition of this embodiment, which comprises the oxidizing agent, can additionally comprise at least one branched (C 6 to C 30 ) fatty acid and/or at least one branched or linear (C8 to C 3 o) dicarboxylic acid. The employed fatty acids are preferably saturated. [0094] According to the invention, particularly preferred branched (C 6 to C 30 ) fatty acids are especially 2-ethylhexanoic acid, isotridecanoic acid, isopalmitic acid, isostearic acid, 2-hexyldecanoic acid and 2-octyldodecanoic acid. [0095] The isostearic acids that are commercialised under the trade names Emersol* 871 and Emersol@ 875, and the isopalmitic acids, such as the commercial product Edenor* IP 95, are quite particularly preferred A particularly preferred C 6 - to C 30 fatty acid is isostearic acid. [0096] The dicarboxylic acid (mixture) that results from the reaction of linoleic acid with acrylic acid has proven to be particularly inventively advantageous as the branched or linear (C 8 to C 30 ) dicarboxylic acid. In fact it is a mixture of 8 (2'-carboxy-4'-hexylcyclohex-5'-ene)-1-octanoic acid and 8-(2'-carboxy-4' hexylcyclohex-5'-ene)-1-octanoic acid. Such compounds are commercially obtainable under the trade names Westvaco Diacid* 1550 and Westvaco Diacid@ 1595 (Manufacturer: Westvaco). [0097] According to the invention, however, the hair root dye composition can also be applied to the hair together with a catalyst that activates the oxidation of the dye precursors, e.g. by atmospheric oxygen. Such catalysts are, for 38 H 06765 example, metal ions, iodides, quinones or certain enzymes. The catalysts can also be used in the presence of an oxidizing agent. [0098] Suitable metal ions are, for example, Zn 2 +, Cu 2 +, Fe2+, Fe 3 *, Mn2+, Mn**, Li , Mg 2 +, Ca2+ and A13+. Zn2+, Cu 2 + and Mn2+ are particularly suitable here. In principle, the metal ions can be employed in the form of any physiologically compatible salt or in the form of a complex compound. Preferred salts are the acetates, sulfates, halides, lactates and tartrates. By use of these metal salts, both the formation of the coloration can be accelerated, and the color tint can be selectively influenced. [0099] Suitable enzymes are, for example, peroxidases, which can considerably enhance the effect of small amounts of hydrogen peroxide. Those enzymes that directly oxidize the oxidation dye precursors with the help of atmospheric oxygen are further inventively suitable, such as, for example, the laccases, or those which produce small amounts of hydrogen peroxide in situ and in so doing biocatalytically activate the oxidation of the dye precursors. Particularly suitable catalysts for the oxidation of the dye precursors are the so-called 2 electron oxidoreductases in combination with the substrates specific therefore, e.g. - pyranose-oxidase and e.g. D-glucose or galactose, - glucose-oxidase and D-glucose, - glycerine-oxidase and glycerine, - pyruvate-oxidase and pyruvic acid or its salts, - alcohol-oxidase and alcohol (MeOH, EtOH), - lactate-oxidase and lactic acid and its salts, - tyrosinase-oxidase and tyrosine, - uricase and uric acid or its salts, - choline oxidase and choline, - amino acid-oxidase and amino acids. [0100] When using oxidizing agents, the actual hair root dyeing composition is expediently prepared directly prior to use by mixing the preparation of the oxidizing agent with the preparation comprising the chromophoric compounds. 39 H 06765 The resulting ready-for-use hair coloration preparation should preferably have a pH in the range 6 to 12. The hair root dye is particularly preferably applied in a weakly alkaline milieu. [0101] There is no need to wash the hair with a shampoo afterwards if a strong surfactant-containing carrier, e.g. a color enhancing shampoo, was used. [0102] Preferably, the hair root dyes of the inventive method comprise the inventive ingredients in a cosmetic carrier. Aqueous, alcoholic or aqueous alcoholic cosmetic carriers are suitable, for example. Such carriers are, for example, creams, emulsions, gels and also surfactant-containing foaming solutions, such as, for example, shampoos, foam aerosols or other preparations that are suitable for use on the hair. However, it is also conceivable to integrate the ingredients into a powdered or tablet-shaped formulation that on dissolving in a solvent such as e.g. water yields an application mixture with the inventive features as the hair root dye. [0103] Aqueous cosmetic carriers comprise at least 50 wt.% water. [0104] In the context of the present invention, aqueous alcoholic cosmetic carriers are understood to mean aqueous carriers comprising 3 to 70% by weight of a C-C 4 alcohol, in particular, ethanol or isopropanol. The compositions according to the invention can additionally comprise further organic solvents, such as, for example, methoxybutanol, benzyl alcohol, ethyl diglycol or 1,2-propylene glycol. Preference here is given to all water-soluble organic solvents. [0105] The hair root dyes of the inventive method can furthermore comprise all active substances, additives and auxiliaries known for such preparations. [0106] In many cases the hair root dyes comprise at least one surfactant, wherein, in principal, not only anionic, but also zwitterionic, ampholytic, non ionic and cationic surfactants are suitable. However, in many cases it has proved advantageous to select the surfactants from among anionic, zwitterionic or non-ionic surfactants. 40 H 06765 [0107] Suitable anionic surfactants for the inventive preparations are all anionic surface-active materials that are suitable for use on the human body. They are characterized by a water solubilizing anionic group, such as e.g. a carboxylate, sulfate, sulfonate or phosphate group and a lipophilic alkyl group containing about 10 to 22 carbon atoms. In addition, the molecule may comprise glycol- or polyglycol ether groups, ester, ether and amide groups as well as hydroxyl groups. Exemplary suitable anionic surfactants are, each in the form of the sodium, potassium and ammonium as well as the mono-, di- and trialkanol ammonium salts with 2 or 3 carbon atoms in the alkanol group, - linear fatty acids containing 10 to 22 carbon atoms (soaps), - ether carboxylic acids of the formula R-O-(CH 2

-CH

2 0)x-CH 2 -COOH, in which R is a linear alkyl group with 10 to 22 carbon atoms and x = 0 or 1 to 16, - acyl sarcosides with 10 to 18 carbon atoms in the acyl group, - acyl taurides with 10 to 18 carbon atoms in the acyl group, - acyl isethionates with 10 to 18 carbon atoms in the acyl group, - sulfosuccinic acid mono- and dialkyl esters with 8 to 18 carbon atoms in the alkyl group and sulfosuccinic acid mono-alkyl polyoxyethyl esters with 8 to 18 carbon atoms in the alkyl group and 1 to 6 oxyethyl groups, - linear alkane sulfonates with 12 to 18 carbon atoms, - linear alpha-olefin sulfonates with 12 to 18 carbon atoms - alpha-sulfo fatty acid methyl esters of fatty acids with 12 to 18 carbon atoms, - alkyl sulfates and alkyl polyglycol ether sulfates of formula R-O(CH 2 CH 2 0).-SO 3 H, in which R is preferably a linear alkyl group with 10 to 18 carbon atoms and x = 0 or 1 to 12, - mixtures of surface active hydroxysulfonates according to DE-A-37 25 030, - sulfated hydroxyalkyl polyethylene- and/or hydroxyalkylene polypropylene glycol ethers according to DE-A-37 23 354, 41 H 06765 - sulfonated unsaturated fatty acids containing 12 to 24 carbon atoms and 1 to 6 double bonds according to DE-A-39 26 344, - esters of tartaric acid and citric acid with alcohols, which represent the addition products of about 2-15 molecules of ethylene oxide and/or propylene oxide on fatty alcohols with 8 to 22 carbon atoms, [0108] Preferred anionic surfactants are alkyl sulfates, alkyl polyglycol ether sulfates and ether carboxylic acids with 10 to 18 carbon atoms in the alkyl group and up to 12 glycol ether groups in the molecule, and especially salts of saturated and particularly unsaturated C 8

-C

22 carboxylic acids, such as oleic acid, stearic acid, isostearic acid and palmitic acid. [0109] Non-ionic surfactants comprise e.g. a polyol group, a polyalkylene glycol ether group or a combination of polyol and polyglycol ether groups as the hydrophilic group. Exemplary compounds of this type are - Addition products of 2 to 30 moles ethylene oxide and/or 0 to 5 moles propylene oxide to linear fatty alcohols with 8 to 22 carbon atoms, to fatty acids with 12 to 22 carbon atoms and to alkyl phenols with 8 to 15 carbon atoms in the alkyl group, - C 12

-C

22 fatty acid mono- and -diesters of addition products of 1 to 30 moles ethylene oxide on glycerine, - C 8

-C

22 alkyl mono- and -oligo glycosides and their ethoxylated analogs as well as - addition products of 5 to 60 mole ethylene oxide on castor oil and hardened castor oil. [0110] Preferred non-ionic surfactants are alkyl polyglycosides of the general formula R'O-(Z)x. These compounds are characterized by the following parameters. [0111] The alkyl group R 1 comprises 6 to 22 carbon atoms and may be both linear and also branched. Primary linear aliphatic groups and aliphatic groups that are methyl-branched in the 2-position, are preferred. Such alkyl groups are for example 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. 1-Octyl, 42 H 06765 1-decyl, 1-lauryl, 1-myristyl are particularly preferred. On using so-called "oxo alcohols" as starting materials, compounds with an odd number of carbon atoms in the alkyl chain preponderate. [0112] The alkyl polyglycosides used according to the invention may simply comprise for example a defined alkyl group R 1 . However normally, these compounds are manufactured from natural fats and oils or mineral oils. In which case, the alkyl groups R are present as mixtures corresponding to the starting compounds or to each of the compounds worked up. [0113] Such alkyl polyglycosides are particularly preferred in which R 1 consists - essentially of Ca- and C10 alkyl groups, - essentially of C12- and C14 alkyl groups, - essentially of Ca- to C1 6 alkyl groups or - essentially of C12- to C16 alkyl groups. [0114] Any mono- or oligosaccharide can be employed as the sugar building block Z. Usually, sugars with 5 or 6 carbon atoms, as well as the corresponding oligosaccharides are used. Such sugars are for example, glucose, fructose, galactose, arabinose, ribose, xylose, lyxose, allose, altrose, mannose, gulose, idose, talose and sucrose. Preferred sugar building blocks are glucose, fructose, galactose, arabinose and sucrose; glucose is particularly preferred. [0115] The alkyl polyglycosides used according to the invention comprise on average 1.1 to 5 sugar units. Alkyl polyglycosides with x-values of 1.1 to 1.6 are preferred. Alkyl polyglycosides with x-values of 1.1 to 1.4 are quite particularly preferred. [0116] Besides their surfactant effect, the alkyl glycosides also serve to improve the fixing of fragrant components on the hair. Thus, when it is desirable for the effect of the perfume oil on the hair to last beyond the hair treatment, the person skilled in the art will preferably have recourse to this class of substances as a further ingredient of the inventive preparations. 43 H 06765 [0117] The alkoxylated homologs of the cited alkyl polyglycosides can also be used according to the invention. These homologs can comprise on average up to 10 ethylene oxide and/or propylene oxide units per alkyl glycoside unit. [0118] Moreover, zwitterionic surfactants can be used, particularly as co surfactants. Zwitterionic surfactants are designated as those surface-active compounds that carry at least one quaternary ammonium group and at least one -C00- or -SO 3 (- group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines such as the N-alkyl-N,N-dimethyl ammonium glycinates, for example the cocoalkyl dimethyl ammonium glycinate, N-acylaminopropyl-N,N-dimethyl ammonium glycinates, for example the cocoacylaminopropyl dimethyl ammonium glycinate, and 2-alkyl-3 carboxymethyl-3-hydroxyethyl imidazolines with 8 to 18 carbon atoms in each of the alkyl or acyl groups, as well as cocoacylaminoethyl hydroxyethyl carboxymethyl glycinate. A preferred zwitterionic surfactant is the fatty acid amide derivative, known under the INCI name cocamidopropyl betaine. [0119] Likewise suitable, in particular as co-surfactants, are ampholytic surfactants. The ampholytic surfactants are understood to include such surface active compounds that apart from a C 8

-

1 8 alkyl or acyl group, comprise at least one free amino group and at least one -COOH or -SO 3 H group in the molecule, and are able to form internal salts. Examples of suitable ampholytic surfactants are N-alkylglycines, N-alkylamino propionic acids, N-alkylamino butyric acids, N-alkylimino dipropionic acids, N-hydroxyethyl-N-alkylamidopropylglycine,

N

alkyltaurines, N-alkylsarcosines, 2-alkylamino propionic acids and alkylamino acetic acids, each with about 8 to 18 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-cocoalkylamino propionate, the cocoacylaminoethylamino propionate and the C 12 -1 8 acyl sarcosine. [0120] According to the invention, surfactants of the type quaternary ammonium compounds, esterquats and the amido amines are particularly employed as the cationic surfactants. [0121] Preferred quaternary ammonium compounds are ammonium halides, particularly chlorides and bromides, such as alkyl trimethyl ammonium 44 H 06765 chlorides, dialkyl dimethyl ammonium chlorides and trialkyl methyl ammonium chloride, e.g. cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, lauryl dimethyl ammonium chloride, lauryl dimethyl benzyl ammonium chloride and tricetyl methyl ammonium chloride, as well as the imidazolium compounds known under the INCI designations Quaternium-27 and Quaternium-83. The long alkyl chains of the abovementioned surfactants have preferably 10 to 18 carbon atoms. [0122] Esterquats are known compounds, which both comprise at least one ester function and also a quaternary ammonium group as structural elements. Preferred esterquats are quaternized ester salts of fatty acids with triethanolamine, quaternized ester salts of fatty acids with diethanolalkylamines and quaternized ester salts of fatty acids with 1,2-dihydroxypropyldialkylamines. Such products are marketed, for example, under the trade names Stepantex*, Dehyquart* and Armocare*. The products Armocare* VGH-70, an N,N-bis(2 palmitoyloxyethyl)dimethyl ammonium chloride, as well as Dehyquart* F-75, and Dehyquart* AU-35 are examples of such esterquats. [0123] The alkylamido amines are normally manufactured by the amidation of natural or synthetic fatty acids and fatty acid fractions with dialkylamino amines. According to the invention, a particularly suitable compound from this substance group is represented by stearamidopropyldimethylamine, commercially available under the designation Tegamid* S 18. [0124] The quaternized protein hydrolyzates illustrate further inventively usable cationic surfactants. [0125] Cationic silicone oils, such as, for example, the commercially available products Q2-7224 (manufacturer: Dow Corning; a stabilized trimethylsilylamodimethicone), Dow Corning® 929 emulsion (comprising a hydroxylamino modified silicone, also referred to as amodimethicone), SM 2059 (manufacturer: General Electric), SLM-55067 (manufacturer: Wacker), and Abil*-Quat 3270 and 3272 (manufacturer: Th. Goldschmidt; diquaternary polydimethylsiloxanes, Quaternium-80) are similarly suitable according to the invention. 45 H 06765 [0126] An example of a suitable cationic surfactant quaternary sugar derivative is the commercial product Glucquat*100, a "lauryl methyl gluceth-10 hydroxypropyl dimonium chloride" according to INCI nomenclature. [0127] For compounds with alkyl groups that are used as surfactants, they may each be pure substances. However, it is normally preferred to start with natural vegetal or animal raw materials for the manufacture of these materials, with the result that mixtures of substances are obtained, which have different alkyl chain lengths that depend on each raw material. [0128] For surfactants, which are represented by the addition products of ethylene oxide and/or propylene oxide to fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution as well as those with a narrow homolog distribution may be used. The term "normal" homolog distribution is understood to mean mixtures of homologs obtained from the reaction of fatty alcohols and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. On the other hand, narrow homolog distributions are obtained if e.g. hydrotalcite, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts. The use of products with a narrow homolog distribution can be preferred. [0129] In addition, the hair root dyeing compositions of the inventive method can comprise further active substances, auxiliaries and additives, such as, for example - non-ionic polymers, such as, for example, vinyl pyrrolidone/vinyl acrylate copolymers, polyvinyl pyrrolidone and vinyl pyrrolidone/vinyl acetate copolymers and polysiloxanes, - cationic polymers, such as quaternized cellulose ethers, polysiloxanes with quaternary groups, dimethyl diallyl ammonium chloride polymers, acrylamide-dimethyl diallyl ammonium chloride copolymers, dimethylaminoethyl methacrylate-vinyl pyrrolidone copolymers quaternized with diethyl sulfate, vinyl pyrrolidone-imidazolinium methochloride copolymers and quaternized polyvinyl alcohol, 46 H 06765 - zwitterionic and amphoteric polymers, such as, for example, acrylamidopropyl trimethyl ammonium chloride/acrylate copolymers and octylacrylamide/methyl methacrylate/tert-butylaminoethyl methacrylate/2 hydroxypropyl methacrylate copolymers, - anionic polymers, such as, for example, polyacrylic acids, crosslinked polyacrylic acids, vinyl acetate/crotonic acid copolymers, vinyl pyrrolidone/vinyl acrylate copolymers, vinyl acetate/butyl maleate/isobornyl acrylate copolymers, methyl vinyl ether/maleic anhydride copolymers and acrylic acid/ethyl acrylate/N-tert-butylacrylamide terpolymers, - structurants such as maleic acid and lactic acid, - hair conditioning compounds like phospholipids, for example soya lecithin, egg lecithin and cephalin, - protein hydrolyzates, particularly those of elastin, collagen, keratin, milk protein, soya protein and wheat protein, their condensation products with fatty acids as well as quaternized protein hydrolyzates, - perfume oils, dimethyl isosorbitol and cyclodextrins, - solvents and solubilizers such as ethanol, isopropanol, ethylene glycol, propylene glycol, glycerine and diethylene glycol, - fiber structure improvers, particularly mono-, di- and oligosaccharides, such as, for example glucose, galactose, fructose, fruit sugar and lactose, - quaternized amines, such as methyl 1-alkylamidoethyl-2-alkylimidazolium methosulfate - defoamers such as silicones, - dyestuffs to color the composition, - anti-dandruff active materials like Piroctone Olamine, zinc Omadine and Climbazole, - photo protective agents, in particular derivatized benzophenones, cinnamic acid derivatives and triazines, - substances for adjusting the pH, such as, for example, customary acids, in particular food acids and bases, 47 H 06765 - active substances, such as allantoin, pyrrolidone carboxylic acids and salts thereof, and bisabolol, - vitamins, provitamins and vitamin precursors, in particular those of groups A, B 3 , B 5 , B 6 , C, E, F and H, - plant extracts such as extracts from green tea, oak bark, stinging nettle, hamamelis, hops, camomile, burdock root, field horsetail, hawthorn, linden flowers, almonds, aloe vera, spruce needles, horse chestnut, sandal wood, juniper, coconut, mango, apricot, lime, wheat, kiwi, melon, orange, grapefruit, sage, rosemary, birch, malva, lady's smock, common yarrow, thyme, lemon balm, rest-harrow, coltsfoot, meristem, ginseng and ginger root, - cholesterol, - thickeners like sugar esters, polyol esters or polyol alkyl ethers, - fats and waxes like spermaceti, beeswax, montan wax and paraffins, - fatty acid alkanolamides, - chelating agents like EDTA, NTA, p-alanine diacetic acid and phosphonic acids, - swelling and penetration agents such as glycerol, propylene glycol monoethyl ether, carbonates, hydrogen carbonates, guanidines, ureas, and primary, secondary and tertiary phosphates, - opacifiers such as latex, styrene/PVP copolymers and styrene/acrylamide copolymers, - pearlizing agents such as ethylene glycol mono- and distearate as well as PEG-3-distearate, - pigments, - stabilizers for hydrogen peroxide and other oxidizing agents, - propellants such as propane-butane mixtures, N 2 0, dimethyl ether, CO 2 and air, - antioxidants. 48 H 06765 [0130] With regard to further optional ingredients and their amounts used, reference is expressly made to the relevant handbooks known to the expert, for example the monograph by K. Schrader, Grundlagen und Rezepturen der Kosmetika, 2nd edition, HQthig Buch Verlag, Heidelberg, 1989. [0131] After step A is completed, the whole head of hair can be optionally treated in step B with a conditioner. All leave-on or rinse-off conditioners known to the person skilled in the art may be used as the conditioners. [0132] A second subject matter of the present application is a kit of a hair root dye, comprising e a container C1, comprising a composition that comprises at least one chromophoric component in a cosmetic carrier, e optionally a container C2, comprising a composition that comprises in a cosmetic carrier at least one branched (C 6 to C 30 ) fatty acid and/or at least one branched or linear (Ca to C 30 ) dicarboxylic acid and/or at least one oxidizing agent and e at least one applicator, wherein " the hair root dye is the composition from container C1 or the mixture of the compositions of container C1 and C2, e the viscosity of the hair root dye at 20 *C is from 2000 to maximum 27 000 mPa s (Brookfield Rotation viscosimeter, Type RTV, spindle 5, 2 rpm). [0133] In a preferred embodiment, the hair root dye comprises as the chromophoric component - at least one developer component optionally in combination with at least one coupler component and/or - at least one combination of component i at least one reactive carbonyl compound with component 49 H 06765 ii at least one compound selected from the group formed by (a) CH-acidic compounds and (b) compounds containing primary or secondary amino groups or hydroxyl groups, selected from primary or secondary aromatic amines, nitrogen-containing heterocyclic compounds and aromatic hydroxy compounds. [0134] The preferred embodiments of the first subject matter of the invention can be analogously assigned to the kit of the second subject matter of the invention. [0135] Besides the applicator, the kit preferably comprises a bowl that is suitable in particular for mixing up the hair root dye and as the container for keeping the hair root dye during the implementation of the inventive method. According to the invention, "a bowl" is understood to mean an open receptacle that possesses a base and a wall on this base, preferably along the edge of the base. The base can be for example triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal, circular or oval. In addition, the wall along its extension, which does not lie in the plane of the base, can be straight or tilted. The wall preferably stands at an angle of 450 to 1350 to the base. An angle of 750 to 1050, particularly 90*, is particularly preferred. The bowl can be opaque or transparent. The bowl can also be a constituent of the packaging, e.g. a so called tray with a reservoir. [0136] When the hair root dye concerns an oxidative hair root dye, then the cosmetic carrier is located in container C1, and comprises at least one developer component optionally in combination with at least one coupler component as the chromophoric component. A composition comprising an oxidizing agent is stored in container C2. The latter comprises in its cosmetic carrier, besides at least one oxidizing agent, additionally at least one branched

It is again preferred here that the container C2 does not contain any oxidizing agent. [0138] The containers C1 and C2 can be different chambers within a two- or multi-chamber container, for example a multi-chamber tube, a multi-chamber aerosol can or a multi-chamber bottle. Such containers are known from the prior art by the person skilled in the art. When removing the contents from a multi-chamber container, the content of the individual chambers is mixed to form the ready-for-use hair roots dye prior to withdrawal of the contents.
