## Title
Dyeing compositions comprising A 1,2-indandione derivative

## Abstract

The present disclosure relates to compositions for dyeing keratin materials, for example compositions for hair dyeing, comprising at least one 1,2-indandione derivative, a method for dyeing using such compositions, and a multicomponent dyeing agent used for carrying out such a method.

## Background
This application claims benefit of U.S. Provisional Application No. 60/637,748, filed Dec. 22, 2004, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. 04 51267, filed Jun. 14, 2004, the contents of which are also incorporated by reference.


The present disclosure relates to compositions for dyeing keratin materials, for instance, compositions for hair dyeing comprising at least one 1,2-indandione derivative, a method for dyeing using such compositions, and a multi-component dyeing agent used for carrying out such a method.
For a long time, many people have sought to modify the color of their skin, of their eyelashes or of their hair, for example, to mask their grey hair. To do this, several technologies have been developed.
It is known to dye human keratin fibers, such as the hair, with dyeing compositions comprising oxidation dye precursors, generally called oxidation bases. These oxidation bases are colorless or slightly colored compounds which, when combined with oxidizing products, give rise, through a process of oxidative condensation, to colored compounds. These dyes are insoluble and are trapped inside the hair fiber.
It is also known that it is possible to vary the shades obtained with these oxidation bases by combining them with couplers or color modifiers. The variety of oxidation bases and couplers that can be used allows for a rich palette of colors to be obtained.
The colors obtained can exhibit good fastness to shampoo. However, the oxidation reaction occurs with the aid of oxidizing products, such as hydrogen peroxide in a basic medium. These oxidizing agents can attack the keratin of the hair, and thus the cosmetic and mechanical properties of the hair can deteriorate considerably in the event of repeated dyeing.
It is also known to dye human keratin fibers by direct dyeing comprising applying to the keratin fibers direct dyes which are colored and dyeing molecules having affinity for the fibers. There may be mentioned, by way of non-limiting examples of direct dyes which are conventionally used, nitro dyes, benzene dyes, anthraquinone dyes, nitropyridine dyes, azo dyes, cationic azo dyes, xanthene dyes, acridine dyes, azine dyes, dyes of the triarylmethane type and natural dyes.
Another method exists for dyeing keratin materials using indandiones, such as 1,2-indandiones and 1,3-indandiones. These dyeing methods are, for example, described in European Patent Application Nos. EP 1010419, EP 1013259, and EP 1300134, and International Patent Application Nos. WO 95/11001 and WO 99/18914.
The colors thus obtained can be very chromatic and may not bring about chemical degradation of keratin, but they have the disadvantage of being only temporary or semi-permanent, that is to say, the colors can fade after only 4 to 5 shampoo washings.
A need therefore exists for systems and methods for dyeing which allow good color-fastness to be obtained without involving the use of oxidizing agents, which are likely to damage keratin materials.
Accordingly, the present disclosure relates to novel dyeing compositions, which make it possible to dye keratin materials, such as the hair, with a color-fastness equivalent or even superior to that obtained by oxidation dyeing. The compositions of the disclosure can be used in the absence of strong oxidizing agents, thereby preserving, for example perfectly, the keratin materials.
The present disclosure therefore relates to a composition for dyeing keratin materials, such as the skin and keratin fibers, comprising, in an appropriate medium, at least one 1,2-indandione derivative chosen from those of formulae (I) and (II)




wherein:

    
    
        X, X1, and X2, which may be identical or different, are chosen from oxygen atoms, sulphur atoms, phosphorus atoms, and CR1R2 radicals;
        R1 and R2, which may be identical or different, are chosen from hydrogen atoms, halogen atoms, C3-C18 alkyl radicals, alkenyl radicals, carboxyl radicals, hydroxycarbonylalkyl radicals, hydrogenocarbonyl radicals, hydrogenocarbonylalkyl radicals, alkylcarboxyalkyloxy radicals, cyano radicals, thiocyano radicals, nitro radicals, nitroso radicals, hydroxyl radicals, hydroxyalkyl radicals, alkoxy radicals, alkenyloxy radicals, aryloxy radicals, amino radicals, alkylamino radicals, dialkylamino radicals, arylalkylamino radicals, diarylamino radicals, alkenylamino radicals, thio radicals, alkylthio radicals, arylthio radicals, alkenylthio radicals, aryl radicals, heteroaryl radicals, and quatemary ammonium radicals, such as tetraalkylammonium, pyridinium, benzothiazolium or imidazolium;
        A, A1 and A2, which may be identical or different, are chosen from fused and non-fused mono- and polyaromatic radicals comprising from 6 to 50 carbon atoms and which may comprise at least one heteroatom chosen from nitrogen, sulphur, oxygen and/or phosphorus;
        L is chosen from a single bond or an aliphatic or aromatic divalent radical, it being possible for the radical to comprise at least one heteroatom chosen from oxygen, sulphur, nitrogen and phosphorus, and it is possible for the radical to be fused with A1 or A2,

with the proviso that the at least one 1,2-indandione derivative chosen from those of formulae (I) and (II) is not chosen from 1,2-indandione:

    
    






The colors thus obtained can exhibit good chromaticity and the compositions can be distinguishable, for instance, due to their weak selectivity and good color-fastness to external agents such as light, shampoos and sweat. Such compositions can be useful for dyeing keratin fibers, such as the hair.
In the above description, the number of carbons ranging from 1 to 18 corresponds, unless otherwise stated, to the number of carbons of the alkyl radicals. When the radical indicated comprises an aryl radical, then the number of carbons can range from 6 to 30 carbons.
As used herein, the term “polyaromatic radical” refers to a radical that comprises at least two aromatic rings, it being possible for the rings of the radical to be fused or non-fused. A monoaromatic radical is a radical which comprises a single aromatic ring.
The rings A, A1 and A2 and also the radicals R1 and R2 may be optionally substituted. When they are substituted, the at least one substituent R can be chosen from, for example, halogens, alkyl groups, alkenyl radicals, carboxyl radicals, alkoxycarbonyls, hydroxycarbonylalkyl radicals, hydrogenocarbonyl radicals, hydrogenocarbonylalkyl radicals, alkylcarboxylalkyloxy radicals, cyano radicals, thiocyano radicals, nitro radicals, nitroso radicals, sulphonato radicals, alkylsulphonamido radicals, hydroxyl radicals, hydroxyalkyl radicals, alkoxy radicals, alkenyloxy radicals, aryloxy radicals, amino radicals, alkylamino radicals, dialkylamino radicals, arylalkylamino radicals, diarylamino radicals, alkenylamino radicals, thio radicals, alkylthio radicals, arylthio radicals, alkenylthio radicals, silyl radicals, alkylsilyl radicals, alkylarylsilyl radicals, arylsilyl radicals, siloxyl radicals, alkylsilyloxy radicals, arylsilyloxy radicals, aryl radicals, heteroaryl radicals, quatemary ammonium radicals, and radicals of the




type wherein B and D, which may be identical or different, are chosen from carbon and nitrogen atoms, and wherein W is chosen from a ring of at least 5 members or an aromatic or heteroaromatic, fused or non-fused polycycle, it being possible for the heteroatom to be chosen from nitrogen, oxygen, sulphur and/or phosphorus. In addition, two adjacent radicals on the rings A, A1 or A2 may together form a dioxy bridge —O—CH2—O—.

According to one embodiment of the present disclosure, the groups X, X1 and X2 are chosen from, for example, CR1R2 radicals. For instance, R1 and R2 can be chosen from hydrogen, halogens, such as bromine, alkoxy radicals, alkyl and aryl radicals, or a fused ring.
The rings A, A1 and A2, can be chosen from, for example benzene, naphthalene, anthracene, thiophene, pyridine and quinoline groups. For instance, in one embodiment of the present disclosure, the rings A, A1 and A2 are chosen from benzene, naphthalene, anthracene and pyridine rings.
As disclosed herein, the rings A, A1 and A2 can be optionally substituted with at least one entity chosen from halogen, C1-C6 alkyl, hydroxyl, C1-C6 alkoxy, amino, imidazolyl, pyridinyl, mono- and di(C1-C6 alkyl)amino, mono- and dihydroxy(C1-C6 alkyl)amino and tri(C1-C6 alkyl)ammmonio, thio, (C1-C6 alkyl)thio, thio(C1-C6 alkyl), (C1-C6 alkyl)carbonyl, hydrogenocarbonyl, hydroxycarbonyl, (C1-C6 alkoxy)carbonyl, nitro, and sulphonato radicals and the corresponding protonated groups such as ammonio. imidazolio and/or pyridinio.
In one embodiment of the present disclosure, A, A1 and A2 are chosen so as to form, with the indandione ring, a system of delocalized π electrons.
By way of non-limiting examples of derivatives of formula (I), there may be mentioned




According to another embodiment of the present disclosure, the derivatives of formula (I) have the formula:




wherein R1 and R2 are as defined above, R is chosen from, for instance, halogens, alkyl radicals, aryl radicals, alkoxy radicals, aryloxy radicals, carboxyl radicals, alkoxycarbonyl radicals, nitro, amino, mono- and dialkylamino radicals, cyano radicals, thiocyano radicals, sulphonato radicals, and alkylsulphonamido radicals, or n, which ranges from 0 to 4, can be equal to 0, 1 or 2. In one embodiment of the present disclosure, R is chosen from halogens, and alkyl and alkoxy radicals.

For the derivatives of formula (II), L can be, for example, chosen from a ring of at least 6 members, or an aromatic or heteroaromatic, fused or non-fused polycycle, it being possible for these rings to be substituted. It is also possible for L to form a ring fused with A1 and/or A2.
The derivatives of formulae (I) and (II) of course also include the corresponding acid addition salts and addition salts with bases.
The 1,2-indandione derivatives chosen from those of formulae (I) and (II) can be obtained from known methods of synthesis, for instance, the syntheses described in International Patent Application No. WO 98/20344, or the article “Design and synthesis of chromogenic and fluorogenic reagents for amino acid detection,” O. Petrovskaïa, thesis from the University of Pennsylvania, 1999.
The derivatives of formula (II) may be synthesized based on the teaching of International Patent Application No. WO 98/20344, and for which the connection between the two 1,2-indandione derivatives is realized according to the methods described in the articles “Ninhydrin and ninhydrin analogs, Syntheses and applications,” M. M. Joullié, T. R. Thompson, N. H. Nemeroff, Tetrahedron, Vol. 47, No. 42, 8791-8830, (1991); “The total synthesis of Ochrobirine,” B. Nalliah, Q. A. Ahmed, R. H. F. Manske, R. Rodrigo, Canadian Journal of Chemistry, 50, 1819 (1972); “Synthesis of Ninhydrin Analogs,” R. R. Hark, PhD, Dissertation in chemistry, University of Pennsylvania, 1996.
In accordance with the present disclosure, the 1,2-indandione derivatives of formula (I) described above may be used alone for dyeing keratin materials. Indeed, these compounds are capable of generating colored molecules with the amine functional groups of keratin (colored reaction).
It is also possible to use the compounds of formula (I) together with at least one activator, which makes it possible to modify the kinetics of reaction of the 1,2-indandione derivative with the keratinous material. Such an activator may be an oxidizing agent, a reducing agent, Brönsted acids, a metal catalyst such as catalysts based on a transition metal such as iron, platinum and palladium, proteins, for instance enzymes, compounds which modify the ionic strength of the medium, such as NaCl salts, compounds comprising a labile hydrogen chosen from those comprising a primary or secondary amine functional group and those comprising an activated methylene functional group. It is of course also possible to use a mixture of such compounds.
According to another embodiment of the present disclosure, the chemical activator is a compound comprising a labile hydrogen chosen from the compounds comprising a primary or secondary amino functional group and the compounds comprising an activated methylene functional group. For example, the compounds with a primary amine or a secondary amine functional group can be aromatic amines.

wherein

R1a is chosen from hydroxyl and amino groups optionally substituted with a C1-4 alkyl, C1-4 hydroxyalkyl or (C1-4 alkoxy)-(C1-4 alkyl) group,
R2a, R3a, R4a, R5a and R6a, which may be identical or different, are chosen from hydrogen atoms, hydroxyl groups, and amino groups, optionally substituted with a C1-4 alkyl, C1-4 hydroxyalkyl or (C1-4 alkoxy)-(C1-4 alkyl) group, or a carboxylic or sulphonic acid group,

When the 1,2-indandione derivatives of formulae (I) and (II) are used in combination with a primary or secondary amine or with a compound comprising an activated methylene functional group, it is necessary to store these different reagents separately in order to avoid a premature color reaction. The reagents are then only brought into contact immediately before application to the hair by freshly mixing two compositions respectively comprising the 1,2-indandione derivatives and the compounds comprising a labile hydrogen or an activated methylene. The reagents may also be brought directly into contact with the hair by applying the various reagents in succession.
The present disclosure also relates to multi-component dyeing agents comprising

    
    
        as a first component, at least one composition (a) comprising at least one 1,2-indandione derivative chosen from those of formulae (I) and (II), and
        as a second component, at least one composition (b) comprising at least one activator which makes it possible to modify the kinetics of reaction of the 1,2-indandione derivative.
    
    


According to one embodiment of the present disclosure, the activator is a compound with a primary or secondary amine functional group, or at least one compound with an activated methylene functional group, as described above.
This multi-component dyeing agent can be provided, for example, in the form of a multi-compartment kit, with at least one first compartment comprising the at least one composition (a) and at least one second compartment comprising the at least one composition (b).
According to the present disclosure, the dyeing composition comprises, in addition to the at least one 1,2-indandione derivative chosen from those of formulae (I) and (II), at least one cosmetic active ingredient.
The at least one cosmetic active ingredient present in the cosmetic compositions of the present disclosure can be chosen from, for example, vitamins; saccharides; oligosaccharides; polysaccharides which are optionally hydrolyzed, or optionally modified; amino acids; oligopeptides; peptides; proteins which are optionally hydrolyzed or optionally modified; polyamino acids; enzymes; fatty acids and alcohols which are optionally branched; animal, vegetable and mineral waxes; ceramides and pseudoceramides; hydroxylated organic acids; UV-screening agents; antioxidants and anti-free-radical agents; chelating agents; antidandruff agents; seborrhoea-regulating agents; soothing agents; cationic, anionic, nonionic and amphoteric surfactants; cationic, anionic, neutral and amphoteric polymers; silicones which are optionally organomodified; mineral, vegetable and animal oils; polyisobutenes and poly(α-olefins); fatty esters; anionic polymers in dissolved or dispersed form; nonionic polymers in dissolved or dispersed form; reducing agents; solvents; hair dyes such as direct dyes or oxidation dye precursors (bases and/or couplers) different from the claimed compounds comprising a primary or secondary amine functional group; oxidants such as hydrogen peroxide optionally combined with persalts; and pigments.
The at least one cosmetic active ingredient, when present, can be present in an amount ranging from 0.001% to 50% by weight, for instance from 0.01% to 20% by weight, such as in an amount ranging from 0.1% to 10% by weight, relative to the total weight of the cosmetic composition.
In one embodiment of the dyeing cosmetic composition according to the present disclosure, the at least one cosmetic active ingredient is chosen from surfactants and/or polymeric agents (polymer), it being possible for these agents to be of a nonionic, cationic, anionic or amphoteric nature.
The compositions of the present disclosure can have a pH ranging from 2 to 12, such as from 6 to 11.
The at least one 1,2-indandione derivative chosen from those of formulae (I) and (II), can be present in an amount ranging, for example, from 0.0001% to 30% by weight, relative to the total weight of the composition.
The compounds comprising a labile hydrogen or an activated methylene, when they are present in the composition of the invention, can be present, for example, in an amount ranging from 0.0001% to 30% by weight, relative to the total weight of the composition.
The present disclosure additionally relates to a method for dyeing a keratin material, for instance keratin fibers, comprising the application of a composition as described above. The composition is left in contact with the keratin material for a period of leave-in time sufficient to obtain the desired color. This period of leave-in time ranges for example, from 5 minutes to 1 hour, such as from 15 minutes to 30 minutes. The colored reaction between the at least one 1,2-indandione derivative and the amine functional groups of the keratin or the compounds comprising a labile hydrogen or an activated methylene which may optionally be present can be accelerated by heating after application to the keratin material. The heating temperature can be less than or equal to 180° C., such as less than or equal to 60° C.
After obtaining the desired color, the keratin material can be, for example, rinsed and washed.
When compounds comprising a labile hydrogen such as primary or secondary amines, or compounds comprising an activated methylene functional group are used, the application of the reagents taking part in the colored reaction can also be performed in two stages. In other words, it is possible to successively apply at least two different compositions, at least one composition (a) comprising at least one 1,2-indandione derivative chosen from those of formula (I) and at least one composition (b) comprising at least one compound comprising a primary or secondary amine functional group or an activated methylene functional group.
The present disclosure also relates to a two-stage dyeing method comprising applying to the keratin material, at least two compositions one after the other, in any order, at least one composition (a) and at least one composition (b) as defined above for the multi-component dyeing agent.
This separate application of the at least two reactive compositions can have the benefit of avoiding the handling of colored compositions and thus can reduce the risks of staining materials such as clothes.
According to one embodiment of the present disclosure, the dyeing method is a method for dyeing keratin fibers, such as the hair.
It is also possible to insert an intermediate rinsing step between the application of the at least one composition (a) and the application of the at least one composition (b).
In a manner similar to that described above, it is possible to heat the keratin material to which the compositions (a) and/or (b) are applied.
According to another embodiment of the present disclosure, the dyeing methods described above are methods for dyeing keratin fibers, such as the hair.
The present disclosure also relates to the methods for using the compositions described above in dyeing keratin materials, such as the hair.
Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
The following examples are intended to illustrate the present disclosure in a non-limiting manner.

The structures of the compounds used are given in the table below:




Each composition was applied to a lock of natural grey hair which was 90% white, and to a lock of permanently waved grey hair which was 90% white for a period of 30 minutes, at the temperature of 600° C. After dyeing, the locks were rinsed and dried.
The color of the locks was measured in the L*a*b* system using a spectrocolorimeter (Minolta CM3600d, 10° angle, D65 illuminant, specular components included). According to this system, L* denotes the intensity, a* and b* indicate two color axes: a* indicates the green/red axis and b* the blue/yellow color axis.
