Substituted metaaminophenols, a process for their preparation, hair-dyeing compositions containing them and a hair-dyeing process

The present invention relates to new substituted metaaminophenols. These compounds can be used as couplers for oxidation hair dyeing, in the presence of oxidation bases.
The invention also relates to a hair-dyeing process using compositions containing the metaaminophenols and a process for the preparation of the new chemical compounds.
One object of the invention is to provide new chemical compounds which can be used as couplers in hair dyes to give strong colourations which are stable to light, have a good resistance to weather and washing, provide compounds which can have a good degree of harmlessness and satisfactory characteristics from the point of view of mutagenesis and which lead, by means of an oxidative reaction with oxidation bases in an alkaline medium, to non-mutagenic indoaniline or indophenol derivatives.
The present invention provides a metaaminophenol of formula (I): ##STR3## wherein Z represents a monohydroxylated or polyhydroxylated hydrocarbon radical of 1 to 6 carbon atoms or an aminoalkyl radical of the formula: ##STR4## wherein n is an integer from 1 to 6 and R.sub.1 and R.sub.2, which are identical or different, represent a hydrogen atom or an alkyl or hydroxyalkyl radical of 1 to 6 carbon atoms or an acyl radical of 1 to 4 carbon atoms, and R represents a hydrogen atom, an alkyl radical or a monohydroxyalkyl or polyhydroxyalkyl, monocarbamylalkyl, dicarbamylalkyl, aminoalkyl, acyl, carbalkoxy, carbamyl or monoalkylcarbamyl radical, the abovementioned alkyl radicals containing 1 to 6 carbon atoms, and its acid salts, particularly the hydrochloride or sulphate, with the proviso that if R represents a hydrogen atom, Z cannot represent --CH.sub.2 CH.sub.2 OH.
Preferably Z represents --CH.sub.2 CH.sub.2 OH, --CH.sub.2 --CHOH--CH.sub.2 OH, --CH.sub.2 --CHOH--CH.sub.3, --CH.sub.2 --CH.sub.2 --NH.sub.2, --CH.sub.2 --CH.sub.2 --NHCH.sub.3, --CH.sub.2 --CH.sub.2 --NHCOCH.sub.3 or ##STR5##
R is preferably a formyl, acetyl or propionyl group if it is an acyl radical or a hydrogen atom.
Chemical compounds similar to compounds of the present invention are described in French Patent No. 1,543,690. However, these compounds are metaaminophenols in which the substituent in the ortho position to the phenol group is OZ.sub.1, wherein Z.sub.1 is a radical containing a hydroxyl group and an amine group at the end of the chain. In the compounds of the formula (I), the group Z is not derived from an alkanolamine but is either a monohydroxylated or polyhydroxylated radical or an alkylamine radical. This difference in structure results in considerable differences in the properties. Compounds described in French Patent No. 1,543,690 .beta.-adrenergic blocking activity (therapy of cardiac complaints), whereas compounds of the formula (I) are essentially of interest in the field of hair dyeing.
The process for the preparation of the compounds of the formula (I) as herein described is novel and has considerable practical advantages compared with the process of preparation described for the similar compounds in French Patent No. 1,543,690. Furthermore, the process according to the invention also has a great advantage compared with the process described in U.S. Pat. No. 3,834,866 for metaaminophenols containing an OCH.sub.3 substituent in the ortho position in which the process of manufacture described requires a nitration step at a temperature above 100.degree. C., which results in the evolution of nitrous vapours and creates difficulties for manufacture on the industrial scale. The reaction of methanol with 3,4-methylenedioxy-1-nitrobenzene in the presence of potassium hydroxide is described in CHEM. PHARM. BULL., 3113-3116, 1978, Volume 26, but this reference does not describe nor suggest the reaction of the more complex alcohol Y--CH.sub.2 OH, in which Y has the meanings indicated earlier.
The compounds of formula (I) or their salts may be obtained by a process comprising in a first step, reacting 3,4-methylenedioxy-1-nitrobenzene, in the presence of a strong base such as potassium hydroxide, with an alcohol of the formula (II):
Y--CH.sub.2 OH (II)
wherein Y represents either a monohydroxyalkyl or polyhydroxyalkyl group of 1 to 5 carbon atoms, or a group of the formula: ##STR6## wherein R.sub.1 and n have the meanings indicated above and R.sub.3 represents a hydrogen atom or an alkyl radical of 1 to 3 carbon atoms and in a second step, the nitro group of the previously obtained compound of formula (III): ##STR7## is reduced to give a compound of formula (IV): ##STR8## wherein Y has the meaning indicated above; and if appropriate, in a third step, according to the desired compound of the formula (I), the compound of formula (IV) is converted by acid hydrolysis, especially with hydrochloric acid if Y comprises an acylated amine group, or by substitution of the extranuclear amine if Y contains an amine group, or by monosubstitution of the aromatic amine.
The reduction of the nitro group of compounds of the formula (III) is preferably carried out using iron in an acetic acid medium or by using cyclohexene in the presence of a palladium/charcoal catalyst.
If the compound of the formula (IV) in which Y contains an acylated amine group, is subjected to hydrolysis with hydrochloric acid, a compound of the formula (V) is obtained: ##STR9## All the compounds of the formulae (IV) and (V), together with their derivatives obtained by substitution of the aromatic or extranuclear amine, cover all the compounds of formula (I). The aromatic or extranuclear amines may be substituted by reaction with, for example, ethyl bromide, glycol bromohydrin, ethyl chloroformate, .beta.-chloroacetamide or acetic anhydride.

The dyeing compositions according to the invention may also contain at least one direct dyestuff, particularly nitro dyestuffs of the benzene series, anthraquinone dyestuffs, indophenols or indoanilines. Examples of direct dyestuffs are 2-methyl-4-amino-5-nitrophenol, 3-N-methylamino-4-nitrophenoxyethanol, 2-N-.beta.-hydroxyethylamino-5-nitroanisole, 2-amino-3-nitrophenol, 3-nitro-4-N-.beta.-hydroxyethylaminophenol, 3-nitro-4-N'-methylamino-N,N-di-.beta.-hydroxyethylaniline, 3-nitro-4-amino-N-.beta.-hydroxyethylaniline, 2-methyl-4-amino-5-nitro-N-.beta.-hydroxyethylaniline and 1,4,5,8-tetraaminoanthraquinone.
In a preferred embodiment, the dyeing composition according to the invention contains from 0.01% to 4% by weight of compound(s) of the formula (I) (and/or of its (their) acid salts), relative to the total weight of the composition.
The cosmetic vehicle of the composition according to the invention comprises at least one customary adjuvant, for example water, solvents, penetrating agents, surface-active agents, thickeners, antioxidants, alkalizing or acidifying agents, sequestering agents, perfumes, filmforming products and treating agents.
The pH of the composition according to the invention is preferably from 8 to 11.5. Examples of alkalizing agents are: aqueous ammonia, alkylamines such as ethylamine or triethylamine, alkanolamines such as mono-, di- or tri-ethanolamine, alkylalkanolamines such as methyldiethanolamine, hydroxides of sodium or potassium and carbonates of sodium, potassium or ammonium.

Preferably, the surface-active agents are present in the composition according to the invention in a proportion of from 0.5 to 55% by weight and advantageously of from 4 to 40% by weight, relative to the total weight of the composition.
Organic solvents can also be added to the composition according to the invention, for example ethanol, isopropanol, glycerol, glycols and their ethers, such as 2-butoxyethanol, ethylene glycol, propylene glycol, the monoethyl ether and the monomethyl ether of diethylene glycol, and analogous solvents. The solvents can advantageously be present in the composition in a proportion from 1 to 40% by weight and preferably of from 5 to 30% by weight, relative to the total weight of the composition.
Examples of thickening products which can be added to the composition according to the invention are sodium alginate, gum arabic, cellulose derivatives such as methylcellulose, hydroxyethylcellulose, hydroxypropylmethylcellulose and the sodium salt of carboxymethylcellulose, and acrylic acid polymers; it is also possible to use inorganic thickeners such as bentonite. Preferably, the thickeners are present in a proportion from 0.5 to 5% by weight, relative to the total weight of the composition, and advantageously from 0.5 to 3% by weight.
Examples of antioxidants which can be added to the composition according to the invention are sodium sulphite, thioglycolic acid, sodium bisulphite, ascorbic acid and hydroquinone. These antioxidants are preferably present in the composition in a proportion of from 0.05 to 1.5% by weight, relative to the total weight of the composition.
As the dyeing composition according to the invention is an oxidative dyeing composition, it generally contains, at the time of use, oxidizing agents such as hydrogen peroxide, urea peroxide or per-salts such as ammonium persulphate.
The dyeing composition according to the invention may, for example, be presented in the form of a liquid, cream, gel or an aerosol or in any other form suitable for dyeing keratin fibres.
The present invention also provides a new hair-dyeing process, in which, at the time of use, a sufficient quantity of oxidizing agent(s) is mixed with a dyeing composition as defined above, the mixture is left to act on the hair for a period, preferably from 10 to 45 minutes and preferably at a temperature from 10.degree. to 50.degree. C., and the hair is rinsed, optionally washed and rinsed again, and dried.
An advantage of the couplers of the formula (I) is that, depending on the structure of the coupler and the associated oxidation base, indoanilines or indophenols can be formed on the hair in an oxidizing alkaline medium, for example in an ammoniacal medium in the presence of hydrogen per oxide. These indoanilines or indophenols are capable of giving the hair various colourations, for example, yellow, red, purple or blue. Thus it is possible to obtain the majority of possible hues within the range of colourations. To illustrate this property, a few examples of colourations covering the whole range of shades are indicated in Table I below.

Another advantage of the couplers of the formula (I) is the fact that, at least in some cases, if they are associated in equimolecular quantities with certain oxidation bases, they make it possible to obtain dark colourations which are essential for obtaining dyes corresponding to natural colourations, and which those skilled in the art call "the background". Hitherto, the background has generally been obtained by means of paraphenylenediamines taken by themselves in an oxidizing medium and the couplers were only involved, in association with oxidation bases, for shading the background. By contrast, the couplers of the formula (I) make it possible, in association with oxidation bases, to produce a background; this is particularly advantageous because the couplers according to the invention are substantially harmless and give rise to non-mutagenic indoanilines and indophenols. These advantages are not always achieved with the background products previously used. Natural dark hues (for example more or less coppery chestnut or purplish grey or black) are obtained, in particular, when the couplers of the formula (I) in which the radical R represents a hydrogen atom or a substituted or unsubstituted alkyl radical are associated in equimolecular quantities with paraphenylenediamines and paraaminophenols. For example, the association of paraphenylenediamine and 2-hydroxy-4-aminophenoxyethanol in equimolecular quantities gives a chestnut colouration on 90% naturally white hair, whereas an analogous coupler of the state of the art, namely 2-methyl-5-aminophenol, leads to an intense purplish red colouration under the same conditions and the association of N,N-di-.beta.-hydroxyethylparaphenylenediamine in equimolecular quantities with the same coupler of the formula (I) as in the previous example leads to a black colouration with violet highlights on bleached hair. Replacement of the coupler of the formula (I) with the same coupler of the state of the art as in the previous example leads to a very bright purple colouration under the same conditions. This possibility of producing dark backgrounds is unexpected for those skilled in the art, who normally use couplers as toners, and it is particularly advantageous on account of the substantial harmlessness of the couplers and of the indoaniline or indophenol compounds to which they lead. As is known, those skilled in the art are unable to predict, from the similar compounds of the state of the art, what the mutagenic characteristics of a new compound will be. It has been found, according to the invention, that the new compounds of the formula (I) are not mutagenic (Ames test on SALMONELLA TYPHIMURIUM (strains TA 1535, 1537, 1538, 98, 100) with or without activation (S.sub.9 support activated with arochlor)). Furthermore, it has been found that the compounds of the formula (I) give rise to non-mutagenic indoanilines and indophenols in the oxidizing alkaline medium in which they are used during hair dyeing, and this is totally surprising when it is known that the indoanilines or indophenols obtained from the similar couplers described in U.S. Pat. No. 3,834,866 are particularly mutagenic (CHEMICAL ABSTRACT SELECTS - PROTON MAGNETIC RESONANCE, Volume 18, 1981, page 1, 95: 75096f).
Couplers of formula (I) make it possible to obtain colourations which are substantially stable to light, weather and washing. This quality is particularly marked for the couplers of the formula (I) in which R represents a hydrogen atom or alkyl, hydroxyalkyl or carbamylalkyl radical. In particular, it is very desirable to obtain colourations which are both warm (coppery mahogany) and of very good quality. This is the case when 2-hydroxy-4-aminophenoxyethanol is associated with paraaminophenols.
