Process for nonpermanently dyeing human hair with indamine indoaniline and indophenol hair dyes

This invention relates to a process for nonpermanently dyeing human hair by applying to the hair a hair dye composition which is prepared immediately prior to applying the same to the hair by incorporating in an aqueous carrier a solid anhydrous dye selected from the group consisting of indamine, indoaniline and indophenol hair dyes.
It is known that there are two general modes of dyeing hair which differ from each other according to the nature of the dye employed and the results achieved therewith. These modes are generally known as permanent and nonpermanent dyeing processes. A permanent dyeing process is characterized by the fact that the resulting dyeing exhibits good fastness to washings, resists several shampooings and is achieved, generally, with oxidation dyes, i.e., colorless dyes which develop the desired coloration in situ under the influence of an oxidizing agent. On the other hand, a nonpermanent dyeing process is characterized by the fact that the resulting dyeing does not exhibit as favorable or comparable fastness to washing characteristics as those attainable in a permanent dyeing process although it does offer the advantage of permitting the user to easily change or modify the color of the hair. Generally nonpermanent dyeing processes utilized direct dyes such as azo, anthraquinone and aromatic nitro dyes. As it is known, however, these direct dyes fail to produce colorations having sufficient transparency or glints or at least not to the degree achievable with the use of oxidation dyes, as in a permanent dyeing process. And it is recognized by those in this field that these aesthetic characteristics are highly desirable in any type of hair dyeing, be it permanent or nonpermanent.
It is also known that indoanilines, indamines and indophenols can be used to dye hair. However, up to the present, their extensive use has been curtailed because of their lack of acceptable stability characteristics in solutions. The applicants have now developed a process which permits the use of these dyes for nonpermanent dyeing of hair, which process consists in using these dyes, not in the form of a prepackaged dyeing solution, as is usually the case with conventional dyeing processes, but by incorporating these dyes in an aqueous solution immediately prior to applying the same to the hair.
Representative indamines, indoanilines and indophenols usefully employed in the process of the present invention are those having the formula,
Y--Ar.sub.1 --N=Ar.sub.2 =X
including tautomers thereof, wherein Ar.sub.1 and Ar.sub.2, each independently, represent an aromatic hydrocarbon or heterocyclic nucleus, each optionally substituted with a member selected from the group consisting of amino, hydroxy, lower alkoxy, lower alkyl, acylamino and halogen such as chlorine and bromine, Y represents a member selected from the group consisting of hydroxy and ##STR1## wherein R.sub.1 and R.sub.2 each independently represent a member selected from the group consisting of hydrogen, lower alkyl, hydroxy lower alkyl and amino lower alkyl with the amine function being optionally substituted or acylated, and X represents a member selected from the group consisting of oxygen, imine and iminium groups, or salts of these compounds.
In this context, lower alkyl and lower alkoxy mean those having 1-4 carbon atoms. Further, the nomenclature adopted for these dyeing compounds corresponds to a numbering of the Ar.sub.1 and Ar.sub.2 nuclei which, in the case of phenyl nuclei, is as follows: ##SPC1##
Representative indamines that can be used in the present invention are hydrochloride of N-[(4'-dimethylamino) phenyl] 3-amino 6-methyl benzoquinonediimine, the monoacetate of N-[(4'-amino 2'-methoxy 5'-methyl) phenyl] 2-aza 3-amino benzoquinonediimine, the double chloride of zinc and N-[4'-(ethyl, .beta.-acetylaminoethyl) -amino phenyl] 3-amino 6-methoxy benzoquinonediimine, the monoacetate of N-[(4'-amino 2'-methoxy 5'-methyl) phenyl] 3-amino 6-methyl benzoquinonediimine and the double chloride of zinc and N-[4'-(ethyl, .beta.-acetylaminoethyl) -amino phenyl] 3-hydroxy benzoquinoneimine N',N'-diethyliminium.
Representative indoanilines that can be used in the present invention are, for instance, N-[(4'-dimethylamino) phenyl] 2,6-dimethyl benzoquinoneimine, N-[(4'-dimethylamino) phenyl] 2,5-dimethyl benzoquinoneimine, N-[4'-amino 2'-methoxy 3',5'-dimethyl) phenyl] 2,6-dimethyl benzoquinoneimine, N-[(4'-amino 2'-methoxy 3',5'-dimethyl) phenyl] 2,5-dimethyl benzoquinoneimine, N-[4'-dimethylamino) phenyl] 3-amino 6-methyl benzoquinoneimine, N-[(4'-amino 2'-methoxy) phenyl] 3-amino 6-methyl benzoquinoneimine, N-[4'-amino 2'-methoxy 5'-methyl) phenyl] 3-acetylamino 6-methyl benzoquinoneimine, N-[(4'-hydroxy) phenyl] 3-amino 6-methoxy benzoquinonediimine, N-[(4'-hydroxy) phenyl] 3-amino benzoquinonediimine and N-[(4'-amino 3'-chloro) phenyl] 3-amino 2,6-dimethyl benzoquinoneimine.
Representative indophenols that can be used in the present invention include N-[(4'-hydroxy) phenyl] 2,6-dimethyl benzoquinoneimine, N-[(4'-hydroxy) phenyl] 2,5-dimethyl benzoquinoneimine, N-[(4'-hydroxy) phenyl] 3-amino 6-methyl benzoquinoneimine and N-[(4'-hydroxy 3',5'-dimethyl) phenyl] 2,6-dimethyl benzoquinoneimine.
Other indophenols, indamines and indoanilines suitably employed are those disclosed in commonly assigned U.S. patent applications Ser. No. 45,564, filed June 11, 1970, now abandoned; Ser. No. 49,905, filed June 25, 1970, now abandoned; Ser. No. 52,739, filed July 6, 1970, now U.S. Pat. No. 3,677,690; Ser. No. 97,395, filed Dec. 11, 1970, now abandoned; Ser. No. 100,433, filed Dec. 21, 1970, now abandoned, and Ser. No. 161,887, now U.S. Pat. No. 3,758,268, (CIP of 52,739,) filed July 12, 1971.
According to the present invention, the indamines, indoanilines and indophenols can be used in powder or tablet form. For purposes of definition the term "powder" is used to designate powders, per se, i.e., discrete particulate matter as well as powders in shaped forms, such as tablets. It is advantageous that the powders used be as finely divided as possible, so that they dissolve rapidly and easily. These powders are kept from all moisture until the time of application.
The powders used in the process according to the invention can also include other direct dyes, in particular, azo dyes, anthraquinone dyes or aromatic nitro derivatives, or again lyophilisate oxidation products with oxidation bases or coupler-oxidation base mixtures. These lyophilisates are described in commonly assigned U.S. patent application Ser. No. 120,353, filed Mar. 2, 1971, now abandoned.
The powders used in the process according to the invention can also include cosmetic resins, optical bluings or other additives usually used in capillary cosmetic such as thickeners, wetting agents, surfactants, swelling agents, penetrating agents or sun filters.
The indamines, indoanilines or indophenols can also be present in these powders simply crystallized or microencapsulated. They can also be in coated form.
The above dye or dyes are put into solution at the time of application by mixing the powder with a suitably selected amount of an aqueous solution of appropriate composition.
The aqueous solution used can be simply made up of water to which, if necessary, there is added a suitable amount of acid or base so as to regulate the pH of the final composition to a value between 4 and 10. The aqueous solution or carrier can also contain one or more low molecular weight alcohols such as ethanol or isopropanol, dyeing adjuvants such as butylglycol or benzyl alcohol, surfactants, sun filters such as benzylidene camphor, optical bluings, antioxidizing agents such as butylhydroxyanisol and/or additives usually used in capillary cosmetics, such as thickeners, wetting agents, swelling agents, penetrating agents or perfumes.
In a particular embodiment of the process according to the invention, the aqueous solution used contains hydrogen peroxide in a proportion of 1 to 6% by weight and the final solution, prepared immediately before application to the hair, constitutes a bleaching dyeing composition.
In another embodiment of the process according to the present invention, the powder and/or aqueous solution can contain one or more cosmetic resins such as polyvinylpyrrolidone having a molecular weight ranging between 40,000-360,000, preferably about 40,000, a copolymer of crotonic acid-vinyl acetate 90%:10% having a molecular weight of 40,000-200,000, preferably 50,000 and a viscosity of 7-9 cp in a 5% solution in tetrachloroethane, a copolymer of vinylpyrrolidone-vinyl acetate (M.W. = 40,000-160,000), 70%:30% to 30%:70%, the preferred proportion being 60%:40% having a viscosity of 3.3-4 cp in 5% solution in ethanol or maleic anhydride-butylvinyl ether copolymers in such a proportion that this resin constitutes 1 to 3% by weight of the final composition. In this case, said final composition, prepared immediately before application to the hair, constitutes a colored hair-setting lotion.
As has already been said, the pH of the hair dye composition, prepared immediately before application to the hair by mixing said powder with said aqueous solution, is usually between 4 and 10, this pH being obtained by adding to the aqueous solution a base or acid in suitable amount. However, it is possible to utilize with some dyes a pH as low as 2.5.
The concentration of indamines, indoanilines or indophenols in the composition that is ready to use can be extremely slight because of the great dyeing power of these compositions. This concentration generally varies between 0.0005% and 2% by weight of the total.
Dyeing of the hair according to the process of the present invention is performed preferably by simply applying the composition which is obtained by mixing the dye powder with the aqueous solution just before application of the same to the hair followed by putting up the hair on rollers or curlers and/or drying the hair, without previously rinsing or washing the hair. However, in another embodiment of this process, it is possible to wash or rinse the hair before putting it up on rollers or curlers or drying it.
The process according to the invention offers the advantage of making it possible to achieve nonpermanent dyeings exhibiting glints and transparency essentially comparable to that achieved in a permanent dyeing process using oxidization dyes, and without having the disadvantage inherent in using oxidation dyes, which are generally applied in the presence of hydrogen peroxide.
The process according to the invention further makes it possible to use temporary unstable dispersions of indamines, indoanilines and indophenols of a higher concentration than the upper solubility limit of these dyes. This fact, plus the ability of using extremely slight concentrations of these dyes, offers the additional advantage of making it possible to obtain a particularly broad range of shades.
The following examples are intended to show the present invention, it being understood that these examples do not present any limiting character.
