Description

COLORING COMPOSITION COMPRISING AT LEAST ONE AZO COLORANT

  FIELD OF THE INVENTION The present application relates to a composition for staining human keratinous fibers comprising at least one cationic azo dye with a julolidine motif and at least one polymeric chain compound. hydrophobic, a method of staining these fibers using such a composition and a device with appropriate compartment.

  It is known to dye human keratinous fibers, in particular the hair, with dyeing compositions comprising oxidation dye precursors, generally known as oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-phenylenediamines. aminophenols and heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds which, combined with oxidizing products, make it possible to access colored species by a process of oxidative condensation with colored compounds.

  It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain compounds. heterocyclic compounds, such as indole compounds. The variety of molecules involved in the oxidation bases and couplers makes it possible to obtain a rich palette of colors. It is also known to dye keratinous fibers by a direct or semi-permanent coloring. The method conventionally used in direct dyeing consists in applying to the keratin fibers direct dyes which are colored and dyestuff molecules having an affinity for the fibers, to be allowed to pause in order to allow the colored molecules to penetrate, by diffusion, inside. hair, then rinse the fibers. In contrast to oxidation dyeing compositions, direct or semi-permanent dyeing compositions can be carried out without the obligatory presence of an oxidizing agent. These dyes can be performed repeatedly without degrading the keratin fiber. It is known, for example, to use nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine or triarylmethane direct dyes. This results in often chromatic colorations which are, however, temporary or semi-permanent because of the nature of the bonds between the direct dyes and the keratin fiber. These interactions make the desorption of dyes from the surface and / or the core of the fiber relatively easy. Therefore, the colorations often have a relative poor resistance to washes or perspiration. Another disadvantage of the known direct coloration lies in the fact that certain shades are insufficiently accessible, such as, for example, bruises and chromatic violets. This is due to the fact that not only relatively few direct dyes make it possible to obtain such colors, but also because some of these dyes are difficult to use because of their too low solubility limit or their insufficient solution stability. which hinders their use in conventional dyeing compositions.

  There is a real need to have stable dyes in solution allowing access to coloring areas different from those generally achieved in color while improving the homogeneity of the coloration obtained, whatever the state of sensitization of the treated fibers. , but also the toughness of the color vis-à-vis external agents such as shampoos, while limiting disgorging that induces risks of stains and risks of color change over time when we associate together chromatic colorants of respective different tenacity.

  These and other objects are achieved by the present invention which therefore relates to a composition for the dyeing of human keratinous fibers, in particular the hair, comprising in a cosmetically acceptable medium, at least one azo cationic compound of formula (I ): AN = N (I) in which A represents: R2 ~ N + X- (la) X- where R ,, R2, identical or not, represent a C1-C4, preferably C1-C2, alkyl radical; advantageously methyl; a represents the bond with the azo group; X- representing a cosmetically acceptable anion; at least one nonpolymeric compound comprising at least one C10-C24 alkyl or alkenyl chain.

  It also relates to a process for staining human keratinous fibers, in particular the hair, wherein said composition is applied to said fibers, allowed to pause and then rinsed the fibers thus treated. The invention finally relates to a multi-compartment device comprising the dye composition according to the present invention.

  These dyes may be obtained, for example, by four different synthetic routes, hereinafter referred to as the A, B, C and D routes respectively. In the following diagrams, the definition of B, a non-cationic precursor of A , responds to the following two formulas: R2

  In the following, HAL signifies a halogen group connected to R 1 by one of its carbon atoms, preferably a chloro, bromo or iodo group, or a dialkylsulfato group of preferably dimethylsulfato or diethylsulfato or methylsulfonato (mesylate) or arylsulfonato (tosylate) 1 / Synthetic route A The compound of formula (I) is obtained in three successive steps in accordance with the following scheme: HNOZ (nitrosylsulfuric acid) BùNH2 BùNN 1 2 3 4 Year 5 The diazonium salt 2 of the heteroaromatic amine BNH 2 1 is prepared by conventional methods (H Zollinger, Color Chemistry, Wiley VCH Ed 2003 and The Chemistry of Synthetic Dyes, Academic Press, London, vol II, 1952). The diazonium salt 2 is then reacted with a compound 3 (a julolidine aromatic amine) to form compound 4. This type of coupling is well known in the literature cited above. The third step is to react the compound 4 with an alkylating reagent, such as an alkyl sulfate, an alkyl halide, an alkyl alkyl sulphonate or an alkyl aryl sulphonate, to form the compound 5: a cationic azo direct dye with julolidine pattern.

  The alkylation reaction is carried out for example in a halogenated solvent (dichloromethane) or ester (ethyl acetate), at a temperature below 150 ° C., preferably at reflux of the solvent. These conditions are notably described in the literature. With reference to this type of reaction, mention may be made, for example, of Advanced Organic Synthesis 5th Ed M. Smith and J. March John Wiley & Sons Ed, 2001 and International Application WO 03/060015.

  2 / Synthetic route B The compound of formula (I) can be obtained by diazotating the para-amine derivative of an aromatic amine with a julolidine 6 unit, and then coupling the obtained diazonium salt 7 with a heterocylate to yield compound 8, then alkylation of the heterocyclic function to give the compound 9 (the cationic azo direct dye julolidine) according to the following scheme: 7 8 AùN = N 6 An 9 All the synthesis steps are described in the literature and references of the pathway 1 are also applicable. More particularly, the second step consists in reacting the previously obtained diazonium salt 7 with a BH heterocycle (according to the above definition of B and H representing a hydrogen atom bonded to B on the position which will then be that of the azo group). .

These reactions are exemplified below by a cationic heterocycle 11 according to the following scheme: leaving group with leaving group = Cl, Br, I, etc HZN, N H A -N H N H 12 10 13

  The reaction to form the compound 12 can be carried out in a polar solvent, preferably an alcohol or DMF, at a temperature below 150 ° C., in the presence, if necessary, of a base which is less nucleophilic than the hydrazine chosen (J. Chem Chem 1996, 39 (2), 570-581). The oxidation can be carried out using the usual oxidants: N-bromosuccinimide, ferric chloride, manganese oxide, chromium oxides, hydrogen peroxide, peracids, preferably in an acid medium and at a temperature below 100 ° C. for less than twenty-four hours. The compound of formula (I) can also be obtained by oxidative coupling. This pathway is described in the literature.
