N-monosubstituted indoanilines as dyestuffs for keratinic fibers

The present invention relates to indoanilines in which the amino group in the 4'-position is monosubstituted.
It is known to dye keratin fibers, more particularly living human hair, by applying to the hair, in the presence of an oxidizing agent such as hydrogen peroxide, added at the time of use, a dyeing composition comprising a mixture, in a suitable cosmetic carrier, of compounds belonging to each of two categories. The first category of compounds, generally called "oxidation bases", comprises mainly para-phenylene-diamines or para-amino-phenols which lead, on oxidation, to para-benzoquinonediimines or to para-benzoquinone-monoimines. The second category of compounds, generally called "coupling agents", comprises meta-amino-phenols, meta-acetylamino-phenols, meta-diamines and meta-diphenols. They are compounds with which the benzoquinonemono or di-imines will react to give rise to dyestuffs called, depending on their structure, indophenols, indoanilines or indamines.
These dyestuffs, from which a range of exceptionally rich shades can be obtained, are primarily noted for the luminous nature and for the rich sheen attainable therewith. However, when a complex dyeing composition is used, that is to say a composition which comprises several bases and several coupling agents, it is often very difficult to predict the contribution which each possible combination of oxidation base and coupling agent will make to the final shade. In other words, firstly, it is very difficult at the start to make an exact prediction as to the final shade, and, secondly, for a given dyeing composition, it is not often easy to be certain of perfect reproducibility. These difficulties are increased by the fact that various side reactions change the final shade. Examples of such side reactions are the formation of compounds of the Bandrowsky base type from the oxidation bases, the recondensation of a molecule of oxidation base with certain indophenols or with certain indoanilines or indamines and the formation of quinones.
An object of the present invention is to provide a process for dyeing keratin fibers, and particularly living human hair, which does not require the addition of an oxidizing agent at the time of use. The present invention also relates to the dyes and dye compositions for use in said process.
The objects of the present invention can be achieved by using certain novel indoanilines which possess the advantage of being able to give a very particularly rich range of extremely luminous shades of excellent aesthetic quality.
It has been found that by varying the nature of the substituent in the 4'-position it is possible to change various characteristics of such dyes, in particular their solubility, affinity and compatibility. Thus, increased solubility can be achieved by introducing a hydroxyalkyl or sulphoalkyl substituent, while the solubility of the dye in an alkaline medium can be improved by introducing a mesylaminoalkyl substituent. The affinity of the dye for keratin fibers can be increased by introducing an aminoalkyl substituent.
The present invention provides a N-monoalkyl-amino-indoaniline of the formula (I) ##STR2## wherein each of R.sub.1 and R.sub.4, which may be identical or different, represents hydrogen, halogen, lower alkyl, lower alkoxy, acylamino or ureido;
each of R.sub.2 and R.sub.3, which may be identical or different, represents hydrogen, halogen, lower alkyl, lower alkoxy, amino, N-(lower alkyl)-amino, N-[hydroxy-(lower alkyl)]-amino, N-[carbamyl-(lower alkyl)]-amino, acylamino or ureido;
each of R.sub.5 or R.sub.6, which may be identical or different, represents hydrogen, halogen, lower alkyl or lower alkoxy, with the proviso that R.sub.5 and R.sub.6 can occupy any two free positions but when they are both other than a hydrogen, at least one of the two occupies a meta-position relative to the --NHR.sub.7 group; and
R.sub.7 represents unsubstituted lower alkyl or substituted lower alkyl, and in particular hydroxy-(lower alkyl), acylamino-(lower alkyl), mesylamino-(lower alkyl), carbamyl(lower alkyl), amino-(lower alkyl), piperidino-(lower alkyl) or morpholino(lower alkyl).
By "lower" alkyl or "lower" alkoxy is meant alkyl or alkoxy containing 1 to 6, preferably 1 to 4, carbon atoms.
The invention also relates to the tautomeric form of the compounds of formula (I), especially those of the formula ##STR3## or in the case where R.sub.3 denotes an optionally mono-substituted amino group, those of the formula ##STR4## wherein R represents hydrogen, lower alkyl, hydroxy-(lower alkyl) or carbamyl-(lower alkyl).
The compounds of this invention can be prepared by condensing a compound of the formula: ##STR5## or an addition salt thereof, on a phenolic compound of the formula ##STR6## or an addition salt thereof.
In formula (IV), Z represents --NH.sub.2 or --NO. When Z denotes --NH.sub.2, R.sub.1 to R.sub.7 are as defined above for formula (I). When Z denotes --NO, R.sub.1 to R.sub.6 are as defined above for formula (I) and R.sub.7 represents unsubstituted lower alkyl.
When Z denotes --NH.sub.2, the condensation is suitably carried out in an aqueous, aqueous-alcoholic or aqueous-acetone medium, at an alkaline pH generally greater than 8 and in the presence of an oxidizing agent, for example, ammonium persulphate, potassium ferricyanide or hydrogen peroxide. Generally the alkaline pH is obtained with ammonia or with an alkaline carbonate preferably sodium carbonate and the reaction is carried out at a temperature from about 0.degree. to 25.degree. C.
When Z denotes -NO, the condensation is generally carried out at a temperature of about 50.degree. C, in an aqueous-ethanolic medium which is neutral or has been rendered alkaline by adding a dilute solution of a base preferably sodium hydroxide.
The present invention also provides a dyeing composition for keratin fibers, and particularly for living human hair, which contains in a compatible vehicle, usually an aqueous or aqueous-alcoholic solution, at least one compound of the present invention.
These dyeing compositions generally contain 0.001 to 2% of compound of formula (I), relative to the total weight of the composition.
The dyeing composition according to this invention can contain the idoanilines of formula (I) as the only dyestuff. It is, however, possible to mix the dyestuffs of this invention with other dyestuffs usually employed for dyeing hair, for example nitrobenzene, azo, anthraquinone, indamine, indophenol and/or other indoaniline dyestuffs. Generally when a dye other than the dye of the present invention is employed, the said other dye or dyes is present in amounts of about 0.001 to 1 percent by weight of said composition.
The compositions according to the present invention are generally in the form of an aqueous or aqueous-alcoholic solution containing one or more compounds of formula (I), which may or may not be mixed with other dyestuffs. They can however also contain, for example, thickeners and be in the form of creams or gels. Suitable thickeners which can be used include cellulosic derivatives such as methyl-cellulose, hydroxyethyl-cellulose and carboxymethyl-cellulose; acrylic polymers such as the sodium salt of polyacrylic acid and ethanolamides of fatty acids, preferably mono- or diethanolamide of fatty acids of copra and carboxyvinyl polymers. The thickener can be present, for instance, in amounts of about 0.5 to 7 percent by weight of said composition.
The dyeing composition can contain, as solvents, water, lower alkanols, for example ethanol or isopropanol, and polyhydric alcohols such as glycols, for example ethylene glycol, propylene glycol, butyl glycol, diethylene glycol and the monomethyl ether of diethylene glycol. The solvent is generally present in amounts of about 1 to 60 percent by weight of said composition.
The compositions can also contain various adjuvants usually employed in cosmetics for the hair, such as wetting agents, for example oxyethylenated alkylphenols and oxyalkylenated fatty alcohol sulphates and sulphonates, dispersing agents, swelling agents, penetrating agents, softeners or perfumes. They can, moreover, be packaged in aerosol containers in the presence of a propellant gas. Suitable propellant gases include nitrogen, nitrous oxide, volatile hydrocarbons such as butane, isobutane or propane, or, preferably, fluorinated hydrocarbons (sold under the name of "Freon") such as dichloridifluoromethane, 1,1-difluoro-methane, 1,2-dichloro-1,1,2,2-tetrafluoro-ethane or 1-chloro-1,1-difluoro-methane; mixtures of two or more hydrocarbons or fluorinated hydrocarbons can also be used.
The pH of the compositions, which can vary within wide limits, is generally from about 5 to 11 and preferably from 7 to 9. The pH can be adjusted by means of an alkali, for example ammonia, mono-, di- or tri-ethanolamine, di- or tri- sodium phosphate, or sodium or potassium carbonate, or by means of an acid, for example acetic acid, lactic acid, phosphoric acid or citric acid.
The dyeing of keratin fibers, particularly living human hair, by means of the dyeing compositions according to the present invention can be carried out in the usual way by applying the composition to the fibers to be dyed, leaving it in contact therewith for about 5 to 30 minutes, and then rinsing the fibers and optionally washing them and drying them.
Depending on the nature of the substituents, the indoanilines of the present invention make it possible to obtain a very wide range of colors ranging from greens to violets via blues; only yellows and oranges are not represented. The dyeings obtained are notable for their luminous nature and their rich sheen, especially a pearly or metallic sheen.
When the compositions according to the invention are in the form of aqueous-alcoholic solutions, they can also contain a cosmetic resin, in which case they form what are commonly called colored wavesetting lotions, which can be applied to wet hair before setting it in waves. These compositions generally contain about 0.001 to 0.5% of a compound of formula (I).
Representative cosmetic resins which can be used in such wavesetting lotions according to this invention include such film-forming polymers as polyvinylpyrrolidone, copolymers of vinylpyrrolidone and vinyl acetate, copolymers of vinyl acetate and an unsaturated carboxylic acid such as crotonic acid, copolymers resulting from the copolymerization of vinyl acetate, crotonic acid and an acrylic or methacrylic ester, copolymers resulting from the copolymerization of vinyl acetate and an alkyl vinyl ether, copolymers resulting from the copolymerization of vinyl acetate, crotonic acid and a vinyl ester of an acid with a long carbon chain (i.e. more than 8 carbon atoms) or an allyl or methallyl ester of an acid with a long carbon chain, copolymers resulting from the copolymerization of an ester derived from an unsaturated alcohol and from an acid with a short carbon chain (i.e. not more than 8 carbon atoms), an unsaturated acid with a short chain and at least one ester derived from a saturated alcohol with a short chain and from an unsaturated acid, and copolymers resulting from the copolymerization of at least one unsaturated ester and at least one unsaturated acid.
Representative preferred resins include polyvinylpyrrolidone having a molecular weight of 10,000 to 360,000; copolymers comprising 10% of crotonic acid and 90% of vinyl acetate having a molecular weight of 10,000 to 70,000; copolymers of vinylpyrrolidone (VP) and vinyl acetate (VA) with a molecular weight of 30,000 to 200,000, the VP/VA ratio being from 30/70 to 70/30; copolymers of maleic anhydride and methyl vinyl ether, the specific viscosity of which, measured at 25.degree. C as 1 g/100 ml solution in methyl ethyl ketone, is from 0.1 to 3.5 centipoises, the ethyl, isopropyl and butyl monoesters of copolymers of maleic anhydride and methyl vinyl ether; copolymers of maleic anhydride and butyl vinyl ether; terpolymers of methyl methacrylate (15-25%), stearyl methacrylate (25-35%) and dimethylaminoethyl methacrylate (52-62%), preferably quaternized, for example by means of dimethyl-sulphate, the viscosity of which, measured at the boiling point of the ether as 5% solution in dimethylformamide, is from 8 to 12 centipoises; and terpolymers of vinyl acetate (75-85%), allyl stearate (10-20%) and allyloxy-acetic acid (3-10%), the viscosity of which, measured at the boiling point of the ether as a 5% solution in dimethylformamide, is from 4.4 to 5 centipoises.
These resins are generally used in an amount from 1 to 3% by weight of the total weight of the composition.
The alcohols which are suitable for producing wavesetting lotions according to the invention are alcohols of low molecular weight, preferably ethanol or isopropanol. These alcohols are suitably employed in an amount from 20 to 70% by weight.
The wavesetting lotions according to the present invention can be employed in the usual way, by applying them to wet hair which has been washed and rinsed beforehand, constraining in a deformed state, for example by winding up on curlers and drying the hair.
The dye composition of the present invention can include a surface active agent as a carrier or as a thickening agent. Representative surface active agents that can usefully be employed include oxyethylenated alcohols, particularly oxyethylenated lauryl alcohol; partially sulfated oxyethylenated lauryl alcohol and preferably a mixture consisting of 19% lauryl alcohol oxyethylenated with 2 moles of ethylene oxide and 81% of the sodium sulfate salt of this same oxyethylenated alcohol; the alkaline or ammonium sulfate salts of long chain fatty alcohols, for example, ammonium lauryl sulfate; and oxyethylenated alkylphenols and preferably nonylphenol oxyethylenated with 4 or 9 moles of ethylene oxide per mole of alkylphenol. The surface active agent is generally employed in amounts of about 2 to 30 percent by weight of said composition.
