## Title
Method of coloring hair using cationic dyes

## Abstract

The cationic dyes of formula (1) specified in claim 1 are suitable especially for colouring keratin-containing fibres, more especially for colouring hair.

## Background
The present invention relates to a method of colouring keratin-containing fibres using cationic imidazole dyes, to novel imidazole dyes and to a process for the preparation thereof.
There is already known from EP-A-714 954 a cationic imidazolazo dye that is suitable for colouring hair and is obtained by diazotising 4-alkoxyaniline, coupling with imidazole, then alkylating and quaternising, and finally reacting with p-phenylenediamine. That dye does not however, meet all the demands made in practice of such direct hair dyes, its stability in aqueous solution, in particular, being unsatisfactory.
It has now been found that disadvantage can be overcome by acylating the free aromatic amino group of such dyes or replacing that group with an alkoxy group. As a result the stability is appreciably improved and the dyes have adequate storage stability also at relatively high pH values, for example at pH values of from 5 to 10, which is of decisive advantage especially for formulations for colouring hair.
The present invention accordingly relates to a method of colouring keratin-containing fibres that comprises treating the fibres with a dye of formula




wherein

    Y1 and Y2 are each independently of the other hydrogen, unsubstituted or substituted C1–C4-alkyl, or halogen,
    R1 and R2 are each independently of the other hydrogen or unsubstituted or substituted C1–C4alkyl,
    R3 and R4 are each independently of the other hydrogen, unsubstituted or substituted C1–C4-alkyl, C1–C4alkoxy or halogen,
    R5 is hydrogen, C1–C4alkyl, C1–C4alkoxy or halogen,
    X is C1–C12alkoxy or a group of formula —N(R6)—CO—R7, wherein R6 is hydrogen or C1–C4alkyl and R7 is hydrogen, C1–C4alkyl or —NH2 and
    A− is an anion.


In accordance with the invention, alkyl radicals are to be understood generally as open-chain or branched alkyl radicals, for example methyl, ethyl, n- and iso-propyl and n-, sec- and tert-butyl.
The alkyl radicals may be mono- or poly-substituted, for example by hydroxy, carboxy, halogen, cyano or C1–C4alkoxy.
The alkoxy radicals may contain from 1 to 12 carbon atoms, preferably from 1 to 4 carbon atoms. They are, for example, methoxy, ethoxy, propoxy, isopropoxy, n-butoxy, isobutoxy, tert-butoxy, n-pentyloxy or n-hexyloxy. The alkoxy groups, too, may be substituted, for example by the radicals mentioned as possible substituents for the alkyl groups, especially by hydroxy or C1–C4alkoxy.
There come into consideration as anion A− both inorganic and organic anions, for example halide, such as chloride, bromide or iodide, sulfate, hydrogen sulfate, methyl sulfate, boron tetrafluoride, aminosulfonate, perchlorate, carbonate, bicarbonate, phosphate, nitrate, benzenesulfonate, formate, acetate, propionate, lactate, and complex anions, such as an anion of a zinc chloride double salt.
The anion is generally governed by the preparation procedure. Preferably, chlorides, hydrogen sulfates, sulfates, methosulfates, phosphates, formates, lactates or acetates are present.
Halogen is to be understood as fluorine, bromine or iodine or, especially, chlorine.
Each of Y1 and Y2 is preferably methyl and especially hydrogen.
Each of R1 and R2 is preferably ethyl, hydroxyethyl or methyl.
R3 and R4 are preferably methoxy, methyl, hydrogen or chlorine.
The preferred meaning of R5 is hydrogen.

Special preference is given in accordance with the invention to the use of dyes of formula




wherein

    R1 and R2 are each methyl or ethyl,
    X is unsubstituted C1–C4alkoxy or a radical —NH—CO—R7, wherein R7 is hydrogen, methyl, ethyl or —NH2 and
    A− is an anion.


The dyes of formula (2) are novel and the invention relates also thereto.
The dyes of formulae (1) and (2) are prepared, for example, by acylating the free amino group in a compound of formula




wherein Y1, Y2, R1, R2, R3, R4, R5 and A− are as defined for formula (1), in a manner known per se. This is carried out, for example, by reaction with an appropriate acid, for example formic acid or acetic acid, an anhydride, for example acetic anhydride, or KOCN.

Compounds of formulae (1) and (2) wherein X is an alkoxy group are obtained, for example, by reacting a compound of formula




wherein Y1, Y2, R1, R2, R3 and R4 are as defined for formula (1) and R8 is C1–C4alkyl, with a p-alkoxy-aniline under reaction conditions known per se.

In one preferred embodiment of the invention dyes of formula (1) or (4) or further cationic dyes are mixed with the other components of the compositions shortly before the applying to the hair.
In addition, the methods of colouring of the present invention can be carried out on hair, with preference being given to locks of hair, locks of bleached hair, bleached hair, middle blonde hair.
Further one preferred embodiment of methods of colouring of the present invention concerns the colouring by a comb.
The present invention relates also to compositions comprising such dyes for colouring keratin-containing fibres.
The compounds of formulae (1) and (2) are present in the compositions according to the invention preferably in an amount of from 0.001% to 5%, especially from 0.01% to 1%, based on the total dyeing composition.
The multiplicity of shades and the colour fastness of the dyes of formulae (1) and (2) used in accordance with the invention can be increased by combination with other dyes used in the field of hair-dyeing compositions. They can be combined very readily both with oxidation dyes and with direct dyes, it being possible for the latter to be of cationic nature or also uncharged. Only in the case of anionic direct dyes is a certain degree of caution required, since precipitation may occur in the formulation under certain circumstances.
In all dyeing compositions, the joint use of a plurality of different dyeing substances is also possible; similarly possible is the joint use of a plurality of different oxidation dye precursors from the group of the developer and coupler compounds, for example aromatic compounds having a primary or secondary amino group, nitrogen-containing heterocycles, aromatic hydroxy compounds or amino acids, as described, for example, in German Patent Application 19 717 224.5, especially page 3, line 31 to page 5, line 8.
The dyes of formulae (1) and (2) according to the invention produce colour shades in the range from reddish-violet to violet, and the fastness properties are excellent. Attention is drawn to the property thereof that allows hair that is already dark in colour still to be distinctly altered in shade.
For colouring hair there are preferably used dyes of formula (1) in admixture with one or more further cationic dyes, especially those described in particular on pages 11 to 27 of WO 95/01772. Especially suitable are dye mixtures comprising a dye of formula (1), and also the yellow dye according to Example 1 and/or the red dye according to Example 4 and/or the orange dye according to Example 46 of WO 95/1772.
In a further embodiment, for the purpose of further modification of colour shades the dyeing compositions according to the invention comprise, in addition to the dyes of formula (1) according to the invention, customary direct dyes, for example from the group of the nitroanilines, nitrophenylenediamines, nitroaminophenols, anthraquinones, indophenols, phenazines, phenothiazines, methines or the compounds known as Arianors, such as, for example, the compounds known by the international names or trade names HC Yellow 2, HC Yellow 4, HC Yellow 6, Basic Yellow 57, Basic Yellow 9, Disperse Orange 3, HC Red 3, HC Red BN, Basic Red 76, Basic Red 2, Basic Violet 14, Basic Blue 3, Basic Blue 6, Basic Blue 7, Basic Blue 9, Basic Blue 12, Basic Blue 26, HC Blue 2, HC Blue 7, HC Blue 12, Disperse Blue 3, Basic Blue 99, HC Violet 1, Disperse Violet 1, Disperse Violet 4, Disperse Black 9, Basic Brown 16 und Basic Brown 17, and also picramic acid, 2-amino-6-chloro-4-nitrophenol, 4-amino-2-nitrodiphenylamine-2′-carboxylic acid, 6-nitro-1,2,3,4-tetrahydroquinoxaline, 4-N-ethyl-1,4-bis(2′-hydroxyethylamino)-2-nitrobenzene hydrochloride and 1-methyl-3-nitro4(2′-hydroxyethyl)-aminobenzene.
Also very suitable for combination with the dyes according to the invention are cationised nitroaniline and anthraquinone dyes, for example those described in the following patent specifications: U.S. Pat. No. 5,298,029, especially in column 2, line 33 to column 5, line 38; U.S. Pat. No. 5,360,930, especially in column 2, line 38 to column 5, line 49; U.S. Pat. No. 5,169,403, especially in column 2, line 30 to column 5, line 38; U.S. Pat. No. 5,256,823, especially in column 4, line 23 to column 5, line 15; U.S. Pat. No. 5,135,543, especially in column 4, line 24 to column 5, line 16; EP-A-818 193, especially on page 2, line 40 to page 3, line 26; U.S. Pat. No. 5,486,629, especially in column 2, line 34 to column 5, line 29; and EP-A-758 547, especially on page 7, line 48 to page 8, line 19.
Also cationic azo dyes, e.g. according to GB-A-2 319 776, as well as the oxazine dyes described in DE-A-29 912 327 and mixtures thereof with the other direct dyes mentioned therein, can likewise readily be combined.
The compositions of the invention according to this embodiment contain the dyes preferably in an amount of from 0.01 to 5% by weight, based on the total dyeing composition.
In addition, the dyeing compositions according to the invention may also contain naturally occurring dyes, such as, for example, henna red, henna neutral, henna black, camomile blossom, sandalwood, black tea, Rhamnus frangula bark, sage, campeche wood, madder root, catechu, sedre and alkanet root. Such colouring methods are described, for example, in EP-A-404 868, especially page 3, line 55 to page 4, line 9.

The dyeing compositions according to the invention result in intense colourations even at physiologically tolerable temperatures of less than 45° C. They are accordingly suitable especially for colouring human hair. For use on human hair, the dyeing compositions can usually be incorporated into an aqueous cosmetic carrier. Suitable aqueous cosmetic carriers include, for example, creams, emulsions, gels and also surfactant-containing foaming solutions, e.g. shampoos or other preparations, that are suitable for use on keratin-containing fibres. Such forms of use are described in detail in Research Disclosure 42448 (August 1999). If necessary, it is also possible to incorporate the dyeing compositions into anhydrous carriers, as described, for example, in U.S. Pat. No. 3,369,970, especially column 1, line 70 to column 3, line 55. The dyeing compositions according to the invention are also excellently suitable for the colouring method described in DE-A-3 829 870 using a colouring comb or a colouring brush.
The dyeing compositions according to the invention may furthermore comprise any active ingredient, additive or adjuvant known for such preparations. The dyeing compositions in many cases comprise at least one surfactant, there being suitable in principle anionic and also zwitterionic, ampholytic, non-ionic and cationic surfactants. In many cases, however, it has proved advantageous to select the surfactants from anionic, zwitterionic and non-ionic surfactants.
Anionic surfactants suitable for use in the preparations according to the invention include all anionic surface-active substances that are suitable for use on the human body. Such substances are characterised by an anionic group that imparts water solubility, for example a carboxylate, sulfate, sulfonate or phosphate group, and a lipophilic alkyl group having approximately from 10 to 22 carbon atoms. In addition, glycol or polyglycol ether groups, ester, ether and amide groups and also hydroxy groups may be present in the molecule. The following are examples of suitable anionic surfactants, each in the form of sodium, potassium or ammonium salts or mono-, di- or tri-alkanolammonium salts having 2 or 3 carbon atoms in the alkanol group:

    
    
        linear fatty acids having from 10 to 22 carbon atoms (soaps),
        ether carboxylic acids of formula R—O—(CH2—CH2—O)x—CH2—COOH, in which R is a linear alkyl group having from 10 to 22 carbon atoms and x=0 or from 1 to 16,

Preferred anionic surfactants are alkyl sulfates, alkyl polyglycol ether sulfates and ether carboxylic acids having from 10 to 18 carbon atoms in the alkyl group and up to 12 glycol ether groups in the molecule, and also especially salts of saturated and especially unsaturated C8–C22carboxylic acids, such as oleic acid, stearic acid, isostearic acid and palmitic acid.
Surface-active compounds that carry at least one quaternary ammonium group and at least one —COO(−) or —SO3(−) group in the molecule are termed zwitterionic surfactants. Zwitterionic surfactants that are especially suitable are the so-called betaines, such as the N-alkyl-N,N-dimethylammonium glycinates, for example cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N,N-dimethylammonium glycinates, for example cocoacylaminopropyl-dimethylammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines having from 8 to 18 carbon atoms in the alkyl or acyl group and also cocoacylaminoethylhydroxyethylcarboxymethyl glycinate. A preferred zwitterionic surfactant is the fatty acid amide derivative known by the CTFA name cocamidopropyl betaine.
Ampholytic surfactants are to be understood as meaning surface-active compounds that, in addition to a C8–C18-alkyl or -acyl group, contain at least one free amino group and at least one —COOH or —SO3H group in the molecule and are capable of forming internal salts. Examples of suitable ampholytic surfactants include N-alkylglycines, N-alkylpropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropyl-glycines, N-alkyltaurines, N-alkylsarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids, each having approximately from 8 to 18 carbon atoms in the alkyl group. Ampholytic surfactants to which special preference is given are N-cocoalkyl-aminopropionate, cocoacylaminoethylaminopropionate and C12-Cleacylsarcosine.
Non-ionic surfactants contain as the hydrophilic group, for example, a polyol group, a polyalkylene glycol ether group or a combination of polyol and polyglycol ether groups.
Such compounds are, for example:

    
    
        addition products of from 2 to 30 mol of ethylene oxide and/or from 0 to 5 mol of propylene oxide with linear fatty alcohols having from 8 to 22 carbon atoms, with fatty acids having from 12 to 22 carbon atoms and with alkylphenols having from 8 to 15 carbon atoms in the alkyl group,
        C12–C22 fatty acid mono- and di-esters of addition products of from 1 to 30 mol of ethylene oxide with glycerol,
        C8–C22alkyl-mono- and -oligo-glycosides and ethoxylated analogues thereof,
        addition products of from 5 to 60 mol of ethylene oxide with castor oil and hydrogenated castor oil,
        addition products of ethylene oxide with sorbitan fatty acid esters,
        addition products of ethylene oxide with fatty acid alkanolamides.
    
    


Examples of cationic surfactants that can be used in the hair-treatment compositions according to the invention are especially quaternary ammonium compounds. Preference is given to ammonium halides, such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides and trialkylmethylammonium chlorides, for example cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryidimethylammonium chloride, lauryldimethylbenzylammonium chloride and tricetylmethylammonium chloride. Further cationic surfactants that can be used in accordance with the invention are quaternised protein hydrolysates.
Also suitable in accordance with the invention are cationic silicone oils, such as, for example, the commercially available products Q2-7224 (manufacturer Dow Corning; a stabilised trimethylsilylamodimethicone), Dow Corning 929 emulsion (comprising a hydroxylamino-modified silicone, which is also referred to as amodimethicone), SM-2059 (manufacturer General Electric), SLM-55067 (manufacturer: Wacker) and also Abil®-Quat 3270 and 3272 (manufacturer Th. Goldschmidt; diquaternary polydimethylsiloxanes, quaternium-80).
Alkylamidoamines, especially fatty acid amidoamines, such as the stearylamidopropyldimethylamine obtainable under the name Tego Amid® 18, are distinguished not only by a good conditioning action but also especially by their good biodegradability Quaternary ester compounds, so-called “esterquats”, such as the methyl hydroxyalkyldialkoyloxyalkylammonium methosulfates marketed under the trade mark Stepantex®, are also very readily biodegradable.
An example of a quaternary sugar derivative that can be used as cationic surfactant is the commercial product Glucquat® 100, according to CTFA nomenclature a “lauryl methyl gluceth-10 hydroxypropyl dimonium chloride”.
The alkyl-group-containing compounds used as surfactants may be single substances, but the use of natural raw materials of vegetable or animal origin is generally preferred in the preparation of such substances, with the result that the substance mixtures obtained have different alkyl chain lengths according to the particular starting material used.
The surfactants that are addition products of ethylene and/or propylene oxide with fatty alcohols or derivatives of such addition products may either be products having a “normal” homologue distribution or products having a restricted homologue distribution. “Normal” homologue distribution is to be understood as meaning mixtures of homologues obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. Restricted homologue distributions, on the other hand, are obtained when, for example, hydrotalcites, alkali metal salts of ether carboxylic acids, alkali metal oxides, hydroxides or alcoholates are used as catalysts. The use of products having restricted homologue distribution may be preferred.
Examples of further active ingredients, adjuvants and additives are as follows:

The constituents of the aqueous carrier are used in the preparation of the dyeing compositions according to the invention in the amounts customary for that purpose; for example emulsifiers are used in concentrations of from 0.5 to 30% by weight and thickeners in concentrations of from 0.1 to 25% by weight of the total dyeing composition.
The pH value of the ready-to-use dyeing preparations are usually from 2 to 11, preferably from 5 to 10.
To colour keratin-containing fibres,-especially to colour human hair, the dyeing compositions are usually applied to the hair in an amount of from 50 to 100 g in the form of the aqueous cosmetic carrier, left there for approximately 30 minutes and then rinsed off or washed off with a commercially available hair shampoo.
The dyes used according to the invention and the optionally used oxidation dye precursors may be applied to the keratin-containing fibres either simultaneously or in succession, the order in which they are applied being unimportant.
The dyes used according to the invention and the optionally used oxidation dye precursors of the compositions according to the invention may be stored separately or together, either in a liquid to paste-like preparation (aqueous or non-aqueous) or in the form of a dry powder. When the components are stored together in a liquid preparation, the preparation should be substantially anhydrous in order to reduce reaction of the components. When they are stored separately, the reactive components are intimately mixed with one another only immediately before use. In the case of dry storage, before use a defined amount of hot (from 50 to 80° C.) water is usually added and a homogeneous mixure prepared.
The following Examples serve to illustrate the invention without limiting the invention thereto. Unless specified otherwise, parts and percentages relate to weight.


EXAMPLE 1
16 g of the Compound of Formula




are introduced into 65 g of acetic anhydride and stirring is carried out for 2 hours at a bath temperature of approximately 75° C., after which time all starting material has disappeared. After cooling, filtration is carried out and then washing with acetic anhydride. In order to remove the acetic anhydride, the filter cake is suspended in 200 ml of isopropanol, and the suspension is stirred for 2 hours and filtered again and washed with isopropanol. 17.8 g of the compound of formula





is obtained in very pure form. In aqueous solution, the compound dyes bleached yak hair a brilliant red-tinged violet.

The acetylation can also be carried out in solvents, for example in water: 110 g of the above-described starting compound are suspended in 300 ml of water and, at a temperature of approximately 70° C., a total of 61.4 g of acetic anhydride (=100% excess) are added over a period of one hour. The reaction mixture is cooled with stirring, then filtered and washed with water. After drying, 122.5 g of the acetylated compound are obtained in which only traces of the starting material are still present.
EXAMPLE 2
With Stirring, 15 g of the Compound of Formula




are slowly added to 30 g of formic acid (98%) and heating is carried out for 3 hours at 65° C. 100 ml of isopropanol are added dropwise to the hot solution, which is then stirred until cold. Filtration followed by thorough washing with isopropanol are carried out. The moist filter cake is first stirred into 65 ml of methanol barely at reflux, and then filtration at 45° C. followed by washing with methanol are carried out. The filter cake is then dissolved hot in 1.5 litres of methanol, the solution is clarified and the mother liquor is concentrated to approximately 85 g using a rotary evaporator, in the course of which there is already partial precipitation of the dye. After cooling suction filtration is carried out, followed by washing with a small amount of methanol and drying. Approximately 9 g of the dye of formula





are obtained. In aqueous solution, the dye colours bleached yak hair a brilliant red-tinged violet.

EXAMPLE 3
10.3 g of the Compound of Formula




are dissolved in 33 ml of 1N hydrochloric acid in an ice-cooled apparatus. 30 g of ice are added to the reaction solution and then, over a period of half an hour, 2.4 g of potassium cyanate are added in portions. Towards the end a honey-like residue forms, which may sometimes block the stirrer. After standing for from 1 to 2 hours in an ice bath, the residue has turned into a brittle mass that can readily be crushed using a glass rod. The suspension, readily stirrable again, still contains significant amounts of starting material and therefore a further 9 ml of HCl (1N) and 1.2 g of KOCN are added. The ice bath is then removed and filtration at room temperature is carried out. The residue is suspended in water again and stirred at 75° C. for 2 hours. After cooling, filtration and washing with water are carried out.

For purification, the residue is dissolved hot in 12 litres of methanol and the solution is clarified by way of a preheated pressurised suction filter. The filtrate is concentrated to approximately 2 litres using a rotary evaporator, the dye precipitating in pure form. Following cooling, filtration and washing with methanol, 24 g of the dye of formula




are obtained. In aqueous solution, the dye colours bleached yak hair a brilliant violet, the shade of which is slightly less red-tinged than that of the formyl-substituted dye of Example 2.

EXAMPLE 4
13 g of p-anisidine are dissolved at approximately 50° C. in 45 g of dimethylformamide in a suitable stirring apparatus. Then, with stirring, 26.7 g of the compound of formula




are added in portions and the mixture is stirred for 80 hours at a bath temperature of 90° C. under nitrogen. While still hot, the reaction mixture is diluted with a further 50 g of dimethylformamide, allowed to cool slightly and filtered at approximately 40° C. The crystalline filter cake is washed with a further 50 g of DMF in portions, and finally thoroughly suction-filtered dry.

In order to remove small amounts of starting material that are still present, the filter cake is suspended in 80 g of water and stirred for 2 hours at a temperature of from 70 to 75° C. After cooling with stirring, filtration is carried out, followed by washing with a total of 50 g of water, in portions, and drying. 22 g of the dye of formula




are obtained. In aqueous solution, the dye colours bleached yak hair a brilliant red-tinged violet.

EXAMPLE 5

0.5 g of phenoxyethanol (Uniphen P23 [Induchem])
0.1 g of perfume (PO Cinque 226482 [drom])
water ad 100
0.06 g of the dye according to Example 4 of the present Application is dissolved in the above base and the pH is adjusted to 6.5 using monoethanolamine. A 1 g strand of undamaged medium-brown human hair (virgin medium-brown hair. lmhair Ltd.) is treated for 20 minutes at room temperature with 2 g of the above dyeing emulsion, and is then rinsed and shampooed once. The hair acquires a very attractive intense aubergine shade having excellent fastness properties.
EXAMPLE 9
A 10% solution of a non-ionic surfactant (PlantarenR 2000 [Henkel]) is adjusted to pH 5.5 using citric acid. The following dyes are dissolved in 100 g of that solution:

Dying Process

    a) Bleached human hair is pretreated with a common permanent wave on the basis of thioglycolic acid at a pH value in the range of 9.0 to 9.5 and then rinsed with water. Afterwards, the hair is treated with the powdery dye composition 1 (M) or 1 (M)I-V to 33(M)I-IV and 40 ml stabilized peroxide solution (6% by weight).


The powdery dye composition is applied for 5 to 10 minutes and then rinsed with water and in following, dried.
The hair is dyed in a brilliant red-tinged violet shade with very good endurance properties with respect to subsequent shampooing.

    b) A fixing solution, composition 3(M), is prepared as given below:

10 g of composition 2(M) is mixed with 80 ml of composition 3(M). The resulting mixture is applied on bleached human hair, which was pretreated with a common permanent wave on the basis of thioglycolic acid at a pH value in the range of 9.0 to 9.5 for 10 minutes. Afterwars the hair is rinsed and dried.
The hair is dyed in a brilliant red-tinged violet shade with very good endurance properties with respect to subsequent shampooing.
This oxidative dying process is also applicable if it is divided in two steps:

    step 1: prefixing with peroxide, and then the removal of rollers
    step 2: after fixing with dying.
