Description

"Agent for changing the color of keratinic fibers containing at least one cationic azo dye having two heterocyclic groups"

The present invention relates to color-changing agents of keratinic fibers, in particular human hair, containing (a) at least one cationic azo dye having two heterocyclic groups.

For the dyeing of keratinic fibers, either direct dyes or oxidation dyes are generally used. Although intensive dyeings with good fastness properties can be obtained with oxidation dyes, the development of the color is generally carried out under the influence of oxidizing agents such. H2O2, which in some cases can result in damage to the fiber. Furthermore, some oxidation dye precursors or certain mixtures of oxidation dye precursors may have a sensitizing effect on persons with sensitive skin. Direct dyes are applied under gentler conditions. Their disadvantage lies in the fact that the dyeings often have only insufficient fastness properties.

Depending on the desired color result, the expert uses substantive dyes of different classes of dyes. The direct dyes known from the prior art include, for example, the class of nitro dyes, the anthraquinone dyes, the azo dyes, the triarylmethane dyes or the methine dyes. All of these classes of dyes should meet a specific requirement profile for use in the cosmetics sector. Thus, direct dyes should provide an intensive dyeing result and have the best possible fastness properties. Due to environmental influences, the color result obtained with substantive dyes should be influenced as little as possible, i. For example, the dyes should have good fastness to washing, lightfastness and rubfastness. Also, chemical influences that the keratinic fibers may be exposed to after the dyeing process (such as perms) should change the color result as little as possible.

In order to achieve lightening at the same time as dyeing, the direct dyes should if possible also be compatible with the usual oxidizing agents used in bleaching processes (such as hydrogen peroxide and / or persulfates).

For the strong lightening of dark hair not only hydrogen peroxide alone, but a combination of hydrogen peroxide and persulfates (eg ammonium persulfate, potassium persulfate and / or sodium persulfate) is used. If, therefore, dark hair is lightened in one step and dyed at the same time in a bright shade, the use of a mixture of hydrogen peroxide, persulfates and a direct dye is advantageous. Although many intensive coloring direct dyes are known to those skilled in the dyeing of hair, but he knows only a very limited range of dyes that the strong oxidative conditions, such as a Mixture of the above oxidizing agents represents survive without decomposition. In addition, the oxidation-stable dyes known from the prior art have serious disadvantages with regard to their other fastness properties.

For the simultaneous dyeing and strong whitening of hair there is thus still a need for dyes with high stability to strong oxidizing agents. Even under these extreme conditions of use, these dyes should not lose their positive fastness and dyeing properties.

It has been found that luminous and intense colorations can be produced in particular with cationic substantive dyes. Cationic dyes are often characterized by a particularly high affinity for keratin fibers, which can be attributed to the interactions of the positive charges of the dyes with negatively charged structural components of the keratinic fibers. Therefore, it is often possible to achieve particularly intensive dyeings with cationic dyes.

For example, the representatives Basic Orange 31 (alternative name: 2 - [(4-aminophenyl) azo] -1,3-dimethyl-1H-imidazolium chlorides, CAS No. 97404-02, which are well-known from the prior art are cationic azo dyes 9) and Basic Red 51 (alternative name: 2 - [((4-dimethylamino) phenyl) azo] -1,3-dimethyl-1H-imidazolium chloride, CAS No. 77061-58-6).

Both dyes stain keratin fibers with outstanding color intensity in orange to red shades. There is still a need for substantive blue dyes which are optimally compatible with these two dyes.

The object of the present application is therefore to provide colorants for keratinic fibers, in particular human hair, which have good performance properties in terms of color depth and fastness properties, in particular light fastness, rubfastness and wash fastness, as well as perspiration and cold wave fastness. In the case of simultaneous use with oxidation dyes and / or oxidants, the direct dyes should have high stability to hydrogen peroxide and other oxidizing agents and not lose their positive fastness and dyeing properties. In addition, as bright and intense colors as possible should be achieved.

In addition, the aforementioned dyes should also be particularly well compatible with the cationic azo dyes Basic Orange 31 and Basic Red 51.

It has now been found that the use of a cationic azo dye of formula (I) whose structure is characterized by the presence of two heterocyclic moieties in cosmetic color-change agents on keratinic fibers results in particularly intense and bright colorations.

The dyes of the general formula (I) have proven to be particularly stable to oxidants, in particular stable to a combination of hydrogen peroxide and persulfates. A first object of the present invention is a means for color-changing keratinic fibers, in particular human hair, contained in a cosmetic carrier

Although the compositions according to the invention are primarily suitable for whitening keratin fibers, in principle there is nothing to prevent their use in other fields as well.

The term "color change of keratin fibers" as used in the invention encompasses any form of color change of the fibers, including in particular color changes encompassed by the terms tinting, bleaching, matting, oxidative dyeing, semi-permanent dyeing, permanent dyeing and temporary dyeing Coloring bleaching is understood to mean the simultaneous lightening and coloring of the keratinic fibers which can be achieved by the simultaneous use of oxidizing agent and dye in the staining modifying agent.

The agents according to the invention contain the substantive dyes of the formula (I) in a cosmetic vehicle. This cosmetic carrier is preferably aqueous, alcoholic or aqueous-alcoholic. For the purpose of hair treatment, such carriers are for example creams, emulsions, gels or surfactant-containing foaming solutions, such as shampoos, foam aerosols or other preparations which are suitable for use on the hair. But it is also possible to provide for storage a powdery or tablet-like formulation. This is then mixed before use in an aqueous solvent or with organic solvents or with mixtures of water and organic solvents to obtain the application mixture. For the purposes of the invention, an aqueous carrier contains at least 40% by weight, in particular at least 50% by weight, of water. In the context of the present invention, aqueous-alcoholic carriers are water-containing compositions containing from 3 to 70% by weight. a Ci -C4-alcohol, in particular ethanol or isopropanol to understand. The compositions according to the invention may additionally contain other organic solvents, for example 4-methoxybutanol, ethyl diglycol, 1,2-propylene glycol, n-propanol, n-butanol, n-butylene glycol, glycerol, diethylene glycol monoethyl ether and diethylene glycol mono-n-butyl ether, contain. Preference is given to all water-soluble organic solvents. Preferred agents according to the invention are characterized in that they additionally comprise a non-aqueous solvent, preferred agents according to the invention containing the solvent in a concentration of 0.1 to 30% by weight, preferably in a concentration of 1 to 20% by weight, very particularly preferably in a concentration of 2 to 10 wt .-%, each based on the agent.

As essential ingredient (a) the agents according to the invention contain at least one substantive dye of the formula (I).

The substituents R 1 to R 7 of the compounds of the formula (I) are described below by way of example: Examples of a C 1 -C 6 -alkyl group are the groups methyl, ethyl, propyl, isopropyl, n-butyl, s-butyl and t-butyl, n- Pentyl and n-hexyl. Propyl, ethyl and methyl are preferred alkyl radicals. Examples of a C2-C6 alkenyl group are vinyl, allyl, but-2-enyl, but-3-enyl and isobutenyl, preferred C2-C6 alkenyl radicals are vinyl and allyl. Halogen atoms are selected from the group chlorine, bromine, fluorine and / or iodine, in which case chlorine and bromine are particularly preferred. Exemplary of a Ci-Ce alkoxy group, the methoxy, the ethoxy and the propoxy group can be mentioned. A nitro group is a grouping -NO2 to understand.

Each substantive dye of the formula (I) has a cationic, heterocyclic end group Het 1. Het 1 is an unsaturated heterocycle with a positive charge that is neutralized by the physiologically compatible counterion X-. Het 1 represents a grouping from the group of formulas (II) to (VII)

Formula (VI) represents a cationic 1, 2,4-thiadiazolium end group.

Formula (VII) represents a cationic pyrazolium end group.

In the formulas (I I) to (VII), a position is in each case marked with an asterisk which indicates the point of attachment of the heterocyclic end group Het 1 with the azo group in the formula (I).

By selecting the end group Het 1, the absorption spectrum of the dye and thus also the coloration of the dye can be influenced.

If intensive dyeings in the blue-violet range and especially in the blue range are desired, it is advantageous if Het 1 stands for a heterocyclic end group of the formula (II).

On the other hand, if it is desired to obtain brilliant colorations in the red region, it is preferable if Het 1 is selected from the heterocyclic end groups of the formulas (III) or (IV).

In addition, with dyes of the formula (I) in which Het 1 is a group selected from the formulas (II), (III) or (IV), it is possible to produce particularly pure and luminous hues. For this reason, it is particularly preferred if the agent (a) according to the invention contains at least one substantive dye of the general formula (I) in which

Het1 stand

In a particularly preferred embodiment, an agent according to the invention is characterized in that it contains (a) at least one substantive dye of the general formula (I) in which

Het1 represents one of the structures (II), (II I) or (IV)

Here, R 1 and R 2 independently of one another can be a hydrogen atom, a C 1 -C 6 -alkyl group, a halogen atom from the group consisting of chlorine, bromine, fluorine or iodine, a C 1 -C 6 -alkoxy group or a nitro group.

Particularly intensive colorations are obtained when R 1 and R 2 independently of one another represent a hydrogen atom or a C 1 -C 6 -alkyl group, more preferably a hydrogen atom or a methyl group.

R1. R 2 independently of one another represent a hydrogen atom or a C 1 -C 6 -alkyl group, preferably a hydrogen atom or a methyl group.

The heterocyclic group Het1 is selected from one of the structures of the formulas (I I) to (VII), these heterocyclic groups carrying the radicals R3, R4, R5 and / or R6.

The radicals R3 and R6 are each positioned on a nitrogen atom of the heterocycle and may independently of one another be a Ci-Ce-alkyl group, a C2-Ce-alkenyl group or a hydroxy-C2-Ce-alkyl group.

The radicals R4 and R5 are each located on a carbon atom of the heterocyclic end groups of the formulas (II) to (VII). R4 and R5 independently of one another represent a hydrogen atom, a C 1 -C 6 -alkyl group, a halogen atom from the group consisting of chlorine, bromine, fluorine or iodine, a C 1 -C 6 -alkoxy group or a nitro group.

It is preferred if R 3 and R 6 independently of one another are a C 1 -C 6 -alkyl group, in particular a methyl group or an ethyl group.

R3, R6 independently of one another are a C 1 -C 6 -alkyl group, preferably a methyl group or an ethyl group. Furthermore, the dyes of the formula (I) according to the invention for the production of attractive and intense color shades are particularly suitable when R4 and R5 are independently a hydrogen atom or a Ci-Ce-alkyl group, in particular a hydrogen atom or a methyl group.

R4, R5 independently of one another represent a hydrogen atom or a C 1 -C 6 -alkyl group, preferably a hydrogen atom or a methyl group.

In summary, a composition according to the invention in a further particularly preferred embodiment is characterized in that it contains (a) at least one substantive dye of the general formula (I) in which

The direct-acting dyes of the formula (I) according to the invention are characterized by the presence of a second heterocycle Het 2. Het 2 is a saturated, uncharged heterocyclic system. Het 2 represents one of the structures of formulas (VI II) to (XII I).

In the formulas (VIII) to (XII I), in each case a position is marked with an asterisk which indicates the point of attachment of the saturated heterocyclic end group with the phenyl ring in formula (I). The structure of the formula (VII I) is a morpholinyl group linked via the N atom.

The structure of formula (IX) is a piperidinyl group linked via the N atom. The structure of formula (X) is a pyrrolidinyl group linked via the N atom. The structure of the formula (XI) is an azepine group linked via the N atom (alternative name: 1-azacycloheptyl group). The structure of formula (XII) is a thiomorpholinyl group linked via the N atom.

The structure of formula (XIII) is a piperazinyl group linked via an N atom. The Piperazinylendgruppe of formula (XIII) further carries the radical R7, which may be a hydrogen atom or a Ci-Ce-alkyl group. Preferably, R7 is a hydrogen atom or a methyl group.

A central object of the present invention was to find dyes with high stability to the usually employed in the bleaching of keratin fibers oxidizing agents (hydrogen peroxide + persulfates). The finding of correspondingly stable dyes allows the simultaneous strong lightening and coloring of keratinic fibers.

In the course of the work leading to this invention it has been found that the oxidation stability of a cationic dye can be improved by the choice of a suitable heterocyclic group Het 2 over an analogous open-chain cationic dye.

The reason for this surprisingly increased oxidation stability could - without being bound to this theory - be the spatial geometry of the dye, since the nitrogen atom is forced by the presence of the heterocycle in a rigid ring system.

The spatial orientation of this ring system may prevent the attack of the oxidant (i.e., the nucleophilic attack, e.g., a hydroxide anion HOO, is hindered by the steric orientation of the ring).

It is particularly preferred in this context if the heterocycle Het 2 stands for one of the structures (VIII), (IX) or (X).

Het 2 represents one of the structures (VI II), (IX) or (X).

In a further preferred embodiment, an agent according to the invention is also characterized in that it contains (a) at least one substantive dye of the general formula (I) in which

Het 2 stands for the structure (XIII)

in which

R7 represents a hydrogen atom or a methyl group.

The dyes of the formula (I) according to the invention are cationic azo dyes which are positively charged. The positive charge is in each case neutralized by the anionic counterion X (of the structural units (II) to (VII)). Here, the cationic organic part is responsible for the coloring of the keratin fibers. The counterion X serves only to preserve the electron neutrality, so that the exact nature of the counterions X does not play a significant role in achieving the desired color result. Since the dyes are used in cosmetic color change agents, the counterion must be physiologically compatible. Physiologically acceptable in this context means suitable for use in the cosmetic (i.e., for use on human hair and human skin). The counterion X is a physiologically acceptable anion, which is preferably selected from the group chloride, bromide, iodide, methyl sulfate, methyl sulfonate, p-toluenesulfonate, acetate, hydrogen sulfate, Vz sulfate or Vz Tetrachlorozinkat.

Chloride is understood as meaning an anion Cl ^" , bromide is understood as meaning an anion Br, and iodide is understood to mean an anion J-." Methylsulfate is understood to mean an anion H3COSO4.

Under methylsulfonate, an anion is ^"understood. Among p-toluenesulfonate anion H3C is (CeH4) ^S03" H3CSO3 understood. By acetate is meant an anion H3CCOO-. By hydrogen sulfate is meant an anion HSO4 ^" .

Vz sulphate is understood to be one-half equivalent of the doubly negatively charged anion SO4 ^{2 "} .Vz tetrachlorozincate is understood to be half the equivalent of the doubly negatively charged anion ZnCU ^2" .

In a further preferred embodiment, an agent for color-changing keratinic fibers is characterized in that it comprises at least one compound of the general formula (I) which is selected from

The amount by weight in this case refers to the total amount of all compounds of the formula (I) contained in the middle, which is related to the total weight of the agent in relation.

In a further preferred embodiment, an agent for dyeing keratinic fibers according to the invention is therefore characterized in that it contains, based on the total weight of the agent, one or more substantive dyes (a) of the formula (I) in a total amount of from 0.01 to 4 , 5 wt .-%, preferably from 0.05 to 2.8 wt .-%, more preferably from 0.1 to 2.2 wt .-% and particularly preferably from 0.2 to 1, 2 wt .-% contains.

The dyes of the general formula (I) can be prepared, for example, by the following method:

Thus, for example, the educt 2-aminothiazole can be converted in concentrated sulfuric acid with nitrosyl sulfuric acid into the diazonium ion:

The reactive diazonium ion then undergoes an azo coupling reaction with a heterocyclic aniline derivative (here N-phenylmorpholine):

The 4-phenylmorpholine which can be used as starting material in the azo coupling reaction is commercially available, for example, from Acros or Aldrich.

Finally, the neutral dimer dye formed in the azo coupling reaction can be double quaternized with quaternizing agents. The quaternization reaction is preferably in one polar aprotic solvents (such as DMSO, DMF etc.). Suitable quaternizing agents are, for example, dimethyl sulfate, methyl bromide or p-toluenesulfonate.

In a particularly preferred embodiment, the agents according to the invention additionally contain at least one surfactant. It has been found that very intense color results could be obtained in particular if the agents according to the invention additionally contained at least one anionic surfactant (b).

Surfactants are amphiphilic (bifunctional) compounds which consist of at least one hydrophobic and at least one hydrophilic moiety. The hydrophobic moiety is preferably a hydrocarbon chain of 8-24 carbon atoms, which may be saturated or unsaturated, linear or branched. With particular preference, this alkyl chain is linear.

For anionic surfactants, the hydrophilic moiety comprises a negatively charged hydrophilic moiety. The negatively charged hydrophilic head group may be, for example, a carboxylic acid group bwz. the salt of a carboxylic acid group, a sulfonic acid group or the salt of the sulfonic acid group, a sulfuric acid ester group or the salt thereof, a phosphonic acid group or the salt of the phosphonic acid group, or a Phosphorsäureestergration or the salt thereof.

The cosmetic agent according to the invention usually comprises an aqueous carrier. In aqueous solution, the abovementioned hydrophilic head groups of the anionic surfactant-such as, for example, the carboxylic acid and the salts of the carboxylic acids-are in an equilibrium whose position is determined by the pH of the agent. If, for example, a fatty acid is used as the anionic surfactant, then a small proportion of the fatty acid is present in aqueous solution in the form of the protonated fatty acid, whereas the major part of the fatty acid is deprotonated in aqueous solution and converted in this way into the salt of the fatty acid. For this reason, the definition of an anionic surfactant also includes a surfactant with a - still protonated - acid group.

An anionic surfactant (b) for the purposes of the present invention contains no cationic groups, ie zwitterionic surfactants are not included in the definition of an anionic surfactant. Anionic surfactants according to the invention are accordingly characterized by the presence of a water-solubilizing, anionic group such as. As a carboxylate, sulfate, sulfonate or phosphate group and a lipophilic alkyl group having about 8 to 30 carbon atoms. In addition, in the molecule, glycol or

Polyglycol ether groups, ester, ether and amide groups and hydroxyl groups may be included.

If the anionic surfactants contain polyglycol ether chains, these may have a conventional, but preferably a narrow homolog distribution.

In other words, the dyeing results were particularly intense when the inventive compositions contained one or more ether carboxylic acids of the formula (B1), and, moreover, if all other anionic surfactants used were only present in minor amounts. The use of the ether carboxylic acid (s) of the formula (B1) as the main surfactant can be quantified by specifying a weight ratio which contains the total amount of anionic surfactants of the formula (B1) present in the total amount of all anionic surfactants (b) present in the composition Relation sets.

In a further particularly preferred embodiment, an agent for dyeing keratinic fibers according to the invention is therefore characterized in that the weight ratio of all the anionic surfactants of the formula (B1) present in the composition to the total amount of the anionic surfactants present in the composition is 0.5, is preferably 0.6, more preferably 0.75, and most preferably 0.9,

wherein the anionic surfactants of the formula (B1) are the following surfactants

(b) 0.23 g of sodium laureth-6-carboxylate (B1) and

(b) 0.10 g of sodium laureth sulfate (2 EO)

The weight ratio of all of the average anionic surfactants of formula (B1) to the total amount of anionic surfactants present in the composition is [0.23 / (0.23 + 0.1)] = 0.69

Example: An agent for coloring keratinic fibers contains:

The means of the first subject of the invention can be used in processes for changing the color of keratinic fibers, as in dyeing processes, but in particular also in processes for the simultaneous bleaching and dyeing of human hair.

The agents according to the invention can be formulated as single-component agents or as multicomponent agents, such as two-component agents or three-component agents, and used accordingly. Separation into multicomponent systems is particularly suitable where incompatibilities of the ingredients are to be expected or feared; the agent to be used in such systems is manufactured by the consumer just prior to use by mixing the component. The agent according to the invention for the color change of keratinic fibers is always understood to mean the ready-to-use agent.

If the agent according to the invention is made available to the user in the form of a one-component agent, then the ready-to-use agent need not first be prepared, but can be taken directly from the container in which it was made up and applied to the keratinic fibers.

Bleaching agents, however, are usually two-component products in which an oxidizing agent-containing component (A1) shortly before application with an (alkalizing) agent

(A2) and this ready-mix mixture is applied to the hair.

In this case, the agent according to the invention is the ready-to-use agent which was prepared shortly before use by mixing (A1) and (A2).

Here, the substantive dyes of the general formula (I) in the component (A1) (i.e., together with the oxidizing agent) or in the component (A2) (together with the

Alkalizing agent) are made up.

It is also possible and in accordance with the invention if the ready-to-use agent is prepared by mixing three components shortly before application to the human hair

- The component (A1) at least one substantive dye of the general formula (I) and at least one alkalizing agent

Component (A2) contains at least one first oxidizing agent (for example hydrogen peroxide) and

- Component (A3) contains at least one second oxidizing agent (eg one or more peroxodisulfate salts). During the exposure time of the agents on the fiber, it may be advantageous to assist the dyeing, color changing or matting process by supplying heat. The heat supply can be done by an external heat source, such as warm air of a hot air blower, as well as, especially in a hair lightening on the living subjects, by the body temperature of the subject. In the latter case, the treated batch is usually covered with a hood. An exposure phase at room temperature is also according to the invention. In particular, the temperature during the exposure time between 20 ° C and 40 ° C, in particular between 25 ° C and 38 ° C. After the end of the exposure time, the remaining dyeing preparation is rinsed with water or a cleaning agent from the hair. As a cleaning agent can be used in particular commercial shampoo, in particular then can be dispensed with the detergent and the rinsing can be done with water when the brightening agent has a strong surfactant-containing carrier.

With regard to further preferred embodiments of the use and method according to the invention, what has been said about the agents according to the invention applies mutatis mutandis.
