Title: Hair dye

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to German Patent Application No. 10 2016 225 382.4, filed Dec. 19, 2016, which is incorporated herein by reference in its entirety. 
     TECHNICAL FIELD 
     The present application relates to an oxidative hair dye, a kit, comprising said dye and a hair dyeing method employing said hair dye. 
     BACKGROUND 
     To achieve permanent, intense colors with corresponding fastness properties, so-called oxidative dyes are used. Said dyes usually contain oxidative dye precursors, so-called developer components and coupler components. The developer components join together or couple with one or more coupler components to form, under the influence of oxidants or atmospheric oxygen, the actual dyes per se. Indeed, the oxidative dyes are exemplified by outstanding, long-lasting color results. To achieve natural-looking colors, however, a mixture from a larger number of oxidative dye precursors (ODP) must normally be used; in many cases, partially-oxidizing dyes are still used to create the tinting effect. 
     Most of the oxidative dyes used for stabilizing the dye precursors during storage and to accelerate the reaction during oxidative application have an alkali pH value, which is set with alkalizing agents such as alkanolamines, ammonia or inorganic bases. 
     To produce the dye, the alkali coloring component is usually mixed with a hydrous hydrogen peroxide solution to form a homogeneous creme or a homogeneous gel, and then applied immediately to the hair to be dyed. This dye mixture remains on the hair for a period of from about 5 to about 60 minutes, until the oxidative formation of the dye on the hair is complete. The dye mixture is then washed out. 
     The aforementioned oxidative precursors (OPC) and alkalizing agents are usually worked into the hair in a cosmetically suitable carrier, such as a creme, for example. The carrier guarantees a homogeneous distribution and an adequate dwell time of the hair dye on the hair. 
     The disadvantage is the complex manufacture of such a creme. The fusing of the fat components and the emulsification process requires a high amount of energy. The subsequent cooling process consumes large quantities of cooling water. 
     A further disadvantage is that a creme has to be packaged in a relatively complex manner. Due to their higher viscosity, cremes are incapable of flowing and cannot be transferred from a storage bottle into the application bottle, in which the hydrogen peroxide solution has already been placed, simply by tipping. Instead, the alkali dye cremes are packed primarily in flexible aluminum tubes, packaging material with high energy and raw material consumption. 
     A higher viscosity of the dye creme is a further disadvantage in terms of producing the application mixture. The alkali dye creme is mixed with the developer preparation by hand. The most homogeneous application mixture possible is required to achieve an effective color result. It must be possible to produce said mixture within the shortest possible time. This is because the oxidation dye precursors start to react as soon as they come into contact with the hydrogen peroxide and the atmospheric oxygen. The fastest possible mixture is achieved most readily if dye creme and developer preparation are as fluid as possible. Conversely, the application mixture itself should be more viscose so that it remains on the hair without dripping.

     The agents as contemplated herein and used as contemplated herein do not contain any saturated or unsaturated non-alkoxylated alkanols having a hydroxy group and from 1 to about 50 carbon atoms in the alk(en)yl group; more particularly, the agents as contemplated herein contain no ethanol, no isopropanol, no linear fatty alcohols such as cetyl- or stearyl alcohol, and no branched alkanols, such as 2-octyldodecanol. 
     Moreover, the agents as contemplated herein contain no saturated or unsaturated alkan carbonic acids having from 1 to about 50 carbon atoms, more particularly no oleic acids and no stearic acids or the salts thereof. 
     Agents preferred as contemplated herein and preferably used as contemplated herein are exemplified in that they contain, relative to their weight, polyethylenglycol(s) having an average molecular weight of from about 100 to about 100,000 g·mol −1  in a total quantity of from about 0-about 0.2 wt. %, preferably from about 0-about 0.1 wt. %. As contemplated herein, polyethylene glycols are compounds of the formula HO(CH 2 CH 2 O) n H, wherein the index n denotes the degree of polymerization and is an integer from 3-about 2300. 
     It has emerged that saturated and unsaturated non-alkoxylated alkanols having a hydroxy group and from 1 to about 50 carbon atoms in the alk(en)yl group, more particularly ethanol and isopropanol, also linear saturated alkanols with two or three hydroxy groups and from 2 to 8 carbon atoms in the alkyl group and polyethylene glycols having an average molecular weight from about 100 to about 100,000 g·mol −1  have a negative impact on the quality of the gel consistency, and therefore the total content thereof, as described above, should be limited and as low as possible. 
     Moreover, agents preferred as contemplated herein and preferably used as contemplated herein preferably contain fatty substances having a melting point of about 30° C. and above at 1013 mbar and a water-solubility of about 0.005 wt. % and below in a total quantity of from about 0-about 0.1 wt. %, preferably 0 wt. %, relative to the weight of the agent. Said fatty substances include waxes, hardened oils and fats, as well as esters from fatty acids and fat alcohols having a melting point of about 30° C. and over at 1013 mbar. 
     Agents preferred as contemplated herein and preferably used as contemplated herein contain, in each case relative to their weight, at least one oil in a total quantity of from about 0.1 to about 2 wt. %, preferably from about 0.2-about 1.5 wt. %, most preferably from about 0.5-about 1 wt. %. 
     A further essential feature of the agent as contemplated herein is the content of at least one oxidation dye precursor. 
     On the basis of their reaction behavior, oxidative dye precursors can be divided into two categories, so-called developer components and coupler components. 
     During the oxidative dyeing process, coupler components do not achieve any significant coloration by themselves. They always require the presence of developer components. Developer components can combine together to form the actual dye. 
     The developer and coupler components are normally used in a free form. In the case of substances with amino groups, however, use of the salt form thereof, more particularly in the form of hydrochlorides and hydrobromides or sulfates, may be preferred.

     In a more preferred embodiment of the present disclosure, the agent as contemplated herein contains at least one partially-oxidizing dye. 
     In oxidative hair dyes, partially-oxidizing dyes often serve to tint unwanted red undertones, which can be produced by the melanin decomposition products, or to tint certain blond tones.

     Moreover, partially-oxidizing dyes that occur in nature, such as Henna red, Henna neutral, Henna black, chamomile blossoms sandalwood, black tea, walnut, Cascara bark, sage, logwood, madder root, catechu, ceder and alkanna root, can also be used. 
     The cosmetic agent according preferably contains at least one partially-oxidizing agent in a total quantity of from about 0.001 to about 10 wt. %, preferably from about 0.01 to about 8 wt. %, more preferably from about 0.1 to about 5 wt. %, most preferably from about 0.5 to about 2 wt. %, relative to the total weight of the cosmetic agent and/or of the composition used as contemplated herein (M1).

     For oxidative hair dyeing, immediately before the application on the hair, the one or more oxidation dye precursors and, where applicable, one or more partially-oxidizing dyes, are usually mixed with a hydrous oxidant-containing composition (M2) to produce the ready-to-use dye and then applied to the hair. In most cases, the agent as contemplated herein (M1) and the oxidant-containing composition (M2) are matched with one another such that, at a mixing ratio of 1 to 1, relative to the parts by weight, the ready-to-use application mixture has an initial concentration of hydrogen peroxide of from about 0.5-about 12 wt. %, preferably from about 2-about 10 wt. %, more preferably from about 3-about 6 wt. % of hydrogen peroxide (calculated as 100% H 2 O 2 ), in each case relative to the weight of the application mixture. However, it is equally possible for the agent as contemplated herein (M1) and the oxidant-containing composition (M2) to be matched to one another such that the concentrations required in the ready-to-use oxidant dye (application mixture) is achieved through mixture ratios other than 1:1, for example through a weight-based mixture ratio of 1:2 or 1:3 or even 2:3. 
     Weight-based mixture ratios preferred as contemplated herein (M1):(M2) are within the range from about 1:0.8 to about 1:2.5, more preferably within the range of from about 1:1 to about 1:2. 
     As contemplated herein, the expression “room temperature” describes the temperature inside the room in which a person would usually use a hair dye, i.e. usually a bathroom or a hairdressing salon, in which a temperature within the range of from about 10-about 29° C. prevails. 
     The leaving of the hair dyeing application mixture in method step iv) in the hair dyeing method as contemplated herein or preferred as contemplated herein can also occur at a minimum of about 30° C., preferably at from about 30-about 60° C., more preferably at from about 32-about 50° C., if the hair is heated by employing a heating hood or a heat radiator, for example. 
     The oxidant preparation (M2) used in the dye kit as contemplated herein and preferred as contemplated herein, as well as in the dyeing method as contemplated herein and preferred as contemplated herein contains, in each case relative to the weight thereof, from about 40-about 96 wt. %, preferably from about 70-about 93 wt. %, most preferably from about 80-about 90 wt. % of water. 
     The oxidant preparation (M2) used in the dye kit as contemplated herein and preferred as contemplated herein, as well as in the dyeing method as contemplated herein and preferred as contemplated herein contains, in each case relative to the weight thereof, from about 0.5 to about 23 wt. %, preferably from about 2.5 to about 21 wt. %, more preferably from about 4 to about 20 wt. %, even more preferably from about 5 to about 18 wt. and most preferably from about 6 to about 12 wt. % of hydrogen peroxide. 
     To stabilize the hydrogen peroxide, the oxidant preparation (M2) has a pH value in the range from about 2.0 to about 6.5, preferably from about 2.5-about 5.5, most preferably from about 2.8 to about 5.0, in each case measured at 20° C. 
     The relatively low viscosity of the agent preferred as contemplated herein (M1) in the range of from about 10,000-about 75,000 mPas, preferably from about 12,000-about 60,000 mPas, more preferably from about 13,000-about 50,000 mPas, most preferably from about 15,000-about 25,000 mPas, in each case measured at 20° C. by employing a Brookfield rotational viscometer at a rotational frequency 4 rpm with Spindle 5, is ideally suited to handle this agent per se (production, placing in plastic bottles, dispensing to produce the mixture with the oxidant preparation). 
     Cation Tenside in the Oxidant Preparation (M2) 
     The oxidant preparation (M2) usually has a low viscosity in the range of from about 10-about 6000 mPas, preferably from about 200-about 5000 mPas, more preferably from about 1000-about 4500 mPas, in each case measured at 20° C. For application on the hair, however, the application mixture ought to have a substantially higher viscosity so that it remains on the hair for the entire exposure time (in the range of from about 5-about 60 minutes, preferably from about 30-about 45 minutes) without dripping. A distinction is drawn here as to whether the application mixture is produced by shaking the two compositions (M1) and (M2) in an application bottle, from which the application mixture is applied to the hair immediately after mixing by employing an application nozzle in the form of a bottle attachment (bottle application), or whether the application mixture is produced by stirring the two compositions (M1) and (M2) in a bowl, from which the application is mixture is applied to the hair immediately after mixing by employing a brush (brush application). The bottle application is particularly suitable for dyes that are sold in retail outlets trade with an application recommendation by the consumer itself. The brush application is particularly suitable for dyes that are produced in the hairdressing salon and applied to the consumer&#39;s hair by the hairdresser. 
     It has unexpectedly emerged that an application mixture having a viscosity particularly suitable for brush application is obtained if the agent as contemplated herein or preferred as contemplated herein (M1) is mixed with an oxidant preparation (M2) containing at least one cation tenside. During the mixing process, the interaction between the at least one sodium polyacrylate and the at least one cation tenside leads to the desired viscosity increase. The pasty consistency of the application mixture thus obtained leads to optimum application properties, more particularly for the brush application. The application mixtures thus achieved, preferably with weight-based mixture ratios (M1):(M2) in the range of from about 1:0.8 to about 1:2.5, more preferably in the range of from about 1:1 to about 1:2, preferably have a viscosity in the range of from about 10000-about 100000 mPas, more preferably from about 12000-about 80000 mPas, most preferably from about 15000-about 40000 mPas, in each case measured at 20° C. (Brookfield viscometer, at a rotational frequency of 4 rpm with Spindle No. 5). 
     In a more preferred embodiment of the present disclosure, the oxidant preparation used as contemplated herein (M2) contains at least one cation tenside, preferably in a total quantity of from about 0.05-about 3 wt. %, more preferably from about 0.1-about 1.5 wt. %, most preferably from about 0.3-about 0.9 wt. %, in each case relative to the weight of the oxidant preparation (M2). 
     Cationic tensides are tensides, i.e. surfactant compounds, each having one or more positive charges. Cationic tensides contain exclusively positive charges. Usually, said tensides are constructed from a hyrdophobic part and a hydrophilic head group, wherein the hydrophobic part normally includes a hydrocarbon structure (e.g. including one or two linear or branched alkyl chains), and the positive charge(s) are localized in the hydrophilic head group. Cationic tensides adsorb at boundary surfaces and aggregate in hydrous solutions above the critical micelle formation concentration to form positively charged micelles. 
     As contemplated herein, preferred cationic tensides are of the type of quaternary ammonium compounds, eterquats and alkyl amidoamines. Preferred quaternary ammonium compounds are ammonium halogenides, such as alkyltrimethylammoniumchloride, dialkyldimethylammoniumchloride, trialkylmethylammoniumchloride, as well as the imidazolium compounds known under the INCI trade names of Quatemium-27 and Quatemium-83. Other preferred quaternery ammonium compounds are tetra alkyl ammonium salts, such as that known under the INCI trade name of Quaternium-52, a poly(oxy-1,2-ethanediyl), ((octadecylnitrilio)tri-2,1-ethanediyl)tris(hydroxy)-phosphate (1:1)-salt, which has the general structural formula (III), wherein x+y+z=10 are 
                         
The long alkyl chains of the aforementioned tensides preferably have from 10 to about 22, more preferably from 12 to 18 carbon atoms. Particularly preferred are behenyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride and cetyl trimethyl ammonium chloride, wherein stearyl trimethyl ammonium chloride is most preferred. Other suitable cationic tensides as contemplated herein are quaternary protein hydrolysates. Alkylamidoamines are usually produced through the amidation of natural or synthetic fatty acids and fatty acid molecules with dialkylaminoamines. As contemplated herein, Tegoamid® S 18 (stearamidopropyldimethylamin) is a suitable compound from this substance group. Esterquats are substances containing both at least one ester function and at least quaternary ammonium group as the structural element. Preferred esterquats are quaternated ester salts of fatty acids with triethanolamine, quaternated ester salts of fatty acids with diethanolalkyl amines and quaternated ester salts of fatty acids with 1,2-dihydroxypropyldialkylamines. Such products are sold under the trade names of Stepantex, Dehyquart and Armocare.
 
     With respect to optimum application properties and optimum dye results, C10-C22 alkyl trimethyl ammonium chloride has proved to be particularly suitable. Particularly preferred oxidant preparations used as contemplated herein (M2) are therefore exemplified in that they contain at least one cation tenside in a total quantity from about 0.1-about 1.5 wt. %, most preferred from about 0.3-about 0.9 wt. %, in each case relative to the weight of the oxidant preparation (M2), wherein preferably at least one tenside, selected from C10-C22 alkyl trimethyl ammonium chlorides, most preferably selected from behenyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride and cetyl trimethyl ammonium chloride, as well as mixtures of said tensides, is contained.
