No. 266,051 Claims priority, application Germany, Mar. 22, 1961, Sch 29,426; Mar. 30, 1962, Sch 31,224 8 Claims. (Cl. 167-88) The present invention relates to a composition and method for dyeing'hair and, more particularl the pres ent invention is concerned with imparting to hair a red, green or blue color or color component such as is frequently desirable for modifying the other dye components in order to give the hair the desired color and usually also a more natural appearance.
The present application is a continuation-in-part of my co-pending application Serial No. 180,867, filed March 19, 1962, now abandoned, and entitled, Composition and Method for Dyeing Hair.
For the dyeing of hair, dye intermediates may be used which upon oxidation will be developed to form the respective dye. Usually oxidation of the dye intermediate is carried out shortly before or during the dyeing of the hair. In most cases, the dye intermediates are aromatic amines which in an alkaline, preferably ammoniacal, medium and possibly with the addition of an oxidizing agent will give to the hair the desired more or less naturally looking color. In order to obtain the desired final coloring of the hair, it is usually required that the colors yellow, red, blue and green are available in order to achieve the desired color tone. This is somewhat similar to the requirements with respect to the dyeing of textiles.
In order to obtain a strong color tone or tint, it is necessary that the above mentioned basic colors achieve a deep and full coloring of the hair. Furthermore, it is important that the desired color of the dyed hair, once it is obtained, will not be changed by subsequent mechanical or chemical treatment of the hair.
The use of so-called shading dyes or modifiers has been suggested in order to obtain more natural hair coloring or certain fashionable shades of hair coloring.
Such modifiers may consist for instance of 1,2 dioxybenzene, 1,3 dioxybenzene, 1,4 dioxybenzene and 1,2,3, trioxybenzene. The above mentioned compounds will modify the color of dyed keratin fibers, particularly of living hair, i.e., the natural hair of a human being, however, only in the direction towards yellow or orange.
Other compounds such as m-diaminobenzene, m-diamino-anisole, m-diaminophenetole, alpha-naphthol and betanaphthol which are also known as modifiers will yield only blue, violet and bluish-red color tones. Furthermore, the last mentioned compounds upon being sub It also has been proposed to improve the color fast-' ness of hair dyes by combining oxidation dyestufis with 3,4-diaminobenzoic acid or salts thereof. However, this combination is suitable only for blond and light brown color tones but is not effective for medium brown, dark brown or black hair dyes. It is also impossible by employing diaminobenzoic acid or its salts to obtain the fashionable bluish shading, nor is it possible in this manner to produce a green hair color which is desired as modifier or complementary color to counteract the undesirable reddish tone or dyed hair.
A clear green color can be obtained with salts of weak organic acids, for instance acetates of 4-amino-diphenylamine which, in the 3 position has been substituted with an alkoxy group. However, these salts are split by hydrolysis and thereby the free base is formed. Thus only a weak slightly green dyeing of the hair isachieved in this manner.
The green hair color, however, is a very important shading or modifying color due to the fact that it is the complementary color to the undesirable reddish tinge so frequently occurring in the dyeing of hair.
A reddish color tone is required, for instance, in order to obtain a fashionable color of dyed, originally dark, hair, as a complementary color for overcoming a greenish tinge and to achieve several nuances of blond.
It has been proposed to obtain yellow to orange colortones on hair by applying various nitrobenzene derivatives such as 2-amino-4-nitrophenol, 4-amino-2-nitrophenol, 4-nitro-1,2-phenylenediamine, 2-nitro-1,4-phenylenediamine or 4,6-dinitr0-2-aminophen0l, however, these are directly acting and not oxidation dyestuffs. Due to the fact that the last mentioned dyestufifs are water soluble, the thus obtained hair color is not of the desired permanency, particularly upon washing of the hair. A further disadvantage of these nitrobenzene derivatives is that hair of varying degree of porosity will be unevenly dyed.
Blue-red oxidative dyeing of hair can be accomplished with a combination of alpha-naphthol and p-toluylenediamine, or of m-phenylenediamine and p-aminophenol. However, only a bluish red color and not a pure red can be obtained in this manner. Furthermore, the depth of the color obtained by using alpha-naphthol is limited due to the poor solubility and the size of the molecules thereof.
It is therefore an object of the present invention to provide a composition of matter and a method by which a strong green modifier color can be imparted to the hair.
It is another object of the present invention to provide a composition of matter and a method by means of which hair can be dyed red or green or blue in a simple and economical manner.
Additional objects and advantages of the present invention will become apparent from a further reading of the description and of the appended claims.
With the above and other objects in view, the present invention is concerned with a composition of matter suitable for use in the oxidative dyeing of keratin fibers which comprises at least one dye intermediate adapted to be oxidized into a dye, and at least one diaminopyridine.
More particularly, the present invention also proposes a composition of matter suitable for use in the oxidative dyeing of hair which comprises at least one dye intermediate adapted to be oxidized to form a dye and selected from the group consisting of p-phenylenediamine, p-toluylenediamine, m-phenylenediamine, m-toluylenediarnine, p-aminophenol,

The present invention also proposes a developer for use in the oxidative dyeing of hair, which comprises an aqueous solution of an oxidizing agent adapted to oxidize an oxidation base of a hair dye, and a diaminopyridine.
Thus, according to the present invention it has been found that stable, strong and acid resistant red, blue and green colorations of hair can be produced by treating the hair with a neutral or slightly alkaline solution, cream or paste containing dye intermediates which may be developed into dyestuffs by being oxidized, and also containing a diaminopyridine.
As oxidizable dye intermediates, primarily those are contemplated which can be used in a neutral or alkaline, preferably slightly alkaline medium.
Preferably, dyeing will be carried out at a pH of between 6.5 and 12, and most preferably ata pH of between 7 and 10. i
For instance, a pure oxidative red of surprisingly high resistance againstmoisturecan be obtained by treating hair, in accordance with the present invention, with an ammoniacal solution, cream or paste containing an oxidation base which by oxidation has been developed into the dye, as Well as 2,5-diaminopyridine and/ or substitution products thereof. 7 V 7 Such dye intermediates which may be oxidized to form a dye are listed for instance under the heading Oxidation Bases in the Colour Index (second edition, volume 3, pages 3593-6601), under the heading Bases and Intermediates for Oxidation'Dyes, on page 504' of Cosmetic Science and Technology, by E. Sag'arin, and under the heading Oxidations'farbstoff, in the Encyklopaedie der technischen Chemie, by 'Ullmann, volume 13 (1962) pages Preferably, one of the following oxidizable dye intermediates, or salts thereof, is used:
p-phenylenediamine p-toluylenediamine m-phenylenediamine r'n-toluylenedi-amine p-aminophenol p-amino-N-dimethylaniline 4,4-diaminodiphenylamine 4-aminodiphenylamine 4-amino-4'-oxydipl1enylamine m-diaminoanisole m-diethylaminophenol Of the diaminopyridines, preferably 2,6-diaminopyridine, 2,5-diaminopyridine and 2,3-diarninopyridine, their substitution products and hydrochlorides thereof are used whereby the following groups are particularly suitable as substituting groups: 1
OH OCH OC H Good results are achieved with the following substituted diaminopyridines:
and substitution products thereof.
The groupswith which 2,5-diaminopyridine may be substituted can be generally described by the following formulae:
wherein each of x x y and y respectively, may be either hydrogen or an alkyl such as CH C H or C H preferably with not more than 5 carbon atoms; or each of y and y respectively, will be either hydrogen or an alkyl as described above x will be hydrogen and x; will have the formula:
wherein each of r and r respectively, may be either hydrogen or an alkyl.
The diaminopyridines which are used according to the present invention, for instance, 2,5-diaminopyridine,
are physiologically harmless. Even persons who are allergic to the para compounds experience no undesirable side effects in connection with these diarninopyridines. In combination with-other compatible compounds such as 2,6-dioxypyridine, 2,3-diaminopyridine and 2,6-diaminopyridine, it is possible to produce with 2,5-diaminopyridine practically all desired hair colors without undesirable physiological side eifects.
Furthermore, 2,5-diaminopyridine, for instance, may be combined with dyestuif precursors known per se, of the type of aromatic amines and/or amino or hydroxy derivatives of aromatic alcohols, such as p-phenylenediamine, p-toluylenediamine, m-phenylenediamine, mtoluylenediamine, p-aminophenol, p-amino-N-dimethylaniline, 4,4'-diaminodiphenylamine, rr-diaminoanisole, mdiethylaminophenol, 2,3-diaminopyridine, 2,6-diaminopyridine, m-aminophenol, o-am-inophenol, alpha-naphthol, 2,6-dioxypyridine,resorcinol, pyrocatechol, pyrogallol, 11ydroxyquinone, phloroglucinol or 2,7-dioxynaphthalene.
In many cases the oxidative development of the oxidation base may be carried out simply by exposure to the oxygen of the air. However, dyestuff formation can be accelerated by the addition of a chemical oxidizing agent, preferably hydrogen peroxide orcompounds including the same.
In the examples described hereinbelow, with the exception of Examples 13 and 14, the incorporation of, per se known, thickening agents, wetting agents, stabilizers, emulsified fats and the like has been omitted. However, it is obviously also within the scope of the present invention to incorporate such agents in the hair dyeing composition.
The present invention thus closes a gap which up to now limited the results achievable in the dyeing of hair with oxidation bases, inasmuch as it is possible in accordance with the present invention to produce strong, acid resistant blue, red, green oxidation colors. Thereby it is possible to overcome the disadvantages discussed further above and to broaden the color range within which exact shading of the dyed'hair can be achieved. In addition, new hair colors differing from those obtainable up to now, can be produced.
It is a further'advant-agetof the present invention that mixtures of diarninopyridine and certain intermediates of oxidation dyes, such asip aminophenol, wil give after a few minutes a stable blue and/ or green hair color, without requiring chemical preparations to serve as oxidizing agents. In otherwords, the oxygen of the air will suffice for oxidizing such dye intermediate or oxidation base under such conditions.
It is also Within the scope of incorporate diaminopyridines in developer solutions used in the dyeing of hair. In this manner it is accomplished that the hair dye intermediates which are developed with an oxidizing developer containing a di-aminopyridine or substitution product thereofl-will maintain their color characteristics for prolonged periods of time, in fact, practically indefinitely. Particularly the slow color change towards red which usually occurs in hair dyedwith oxidation dyes, after periods of daysor weeks, is prevented by incorporating in the developer solution a 2,6- or 2,3- diaminopyridine.
The components which are required according to the present invention may-be used in the form of neutral or slightly alkaline liquids or pastes. Preferably, the dyeing composition is supplied to the consumer in two separate portions, of which one contains the dye intermediate and possibly also a pH controlling agent so as to assure a neutral or slightly alkaline environment during dyeing, while the other portion will contain the diarninopyridine compound and possibly also an' oxidizing agent.
It is also possible to supply those portions or components of the dyeing composition in dry state, for instance the oxidation base and the diarninopyridine compound in the form of their solidsalts, the oxidizing agent as a hydrogen peroxide-urea adduct, and the pH controlling agent as an alkali-ammonium carbonate or a guanidine carbon- -ate.- Furthermore, a thickening agent in dry solid form may be added, such as carboxymethyl cellulose, gelatine or glycerol-monostearate. w
