Description




The subject-matter of the invention is a composition for the oxidation dyeing of keratinous fibres, in particular human keratinous fibres, such as hair, comprising, as coupler, at least one thiazoloazole S-oxide compound and/or at least one thiazoloazole S,S-dioxide compound and at least one oxidation base.




It is known to dye keratinous fibres and in particular human hair with dyeing compositons comprising oxidation dye precursors, in particular ortho- or para-phenylenediamines, ortho- or para-aminophenols, or heterocyclic compounds, generally known as oxidation bases. Oxidation dye precursors or oxidation bases are colourless or weakly coloured compounds which, in combination with oxidizing products, can give rise, by an oxidative coupling process, to coloured and colouring compounds.




It is also known that it is possible to vary the shades obtained with these oxidation bases by combining them with couplers or colouring modifers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds, such as indole compounds.




The variety of the molecules involved as oxidation bases and couplers makes it possible to obtain a rich palette of colours.




The so-called “permanent” colouring obtained by virtue of these oxidation dyes has, however, to satisfy a certain number of requirements. Thus, it must be without disadvantage toxicologically and it must make it possible to obtain shades with the desired intensity and behave well in the face of external agents (light, bad weather, washing, permanent waving, perspiration or rubbing).




The dyes must also make it possible to cover white hair and, finally, be as non-selective as possible, that is to say make it possible to obtain the smallest possible differences in colouring along the same keratinous fibre, which can in fact be differently sensitized (i.e. damaged) between its tips and its root.




The Applicant Company has not just discovered that it is possible to obtain powerful novel dyes, which are not very selective, which are particularly resistant and which are capable of generating intense colourings in varying shades, by using, as couplers, thiazoloazole S-oxide and/or thiazoloazole S,S-dioxide compounds in the presence of an oxidation base.




This discovery forms the basis of the present invention.




The subject-matter of the invention is a composition for the oxidation dyeing of keratinous fibres and in particular of human keratinous fibres, such as hair, charactierized in that it comprises, in a medium appripriate for dyeing:




as coupler, at least one thiazoloazole S-oxide compound and/or at least one thiazoloazole S,S-dioxide compound of formula (I) and/or at least one of their addition salts with an acid:

The dyeing composition according to the invention can also include various adjuvants conventionally used in hair dyeing compositions, such as anionic, cationic, non-ionic, amphoteric or zwitterionic surface-active agents or their mixtures, anionic, cationic, non-ionic, amphoteric or zwitterionic polymers or their mixtures, inorganic or organic thickening agents, antioxidizing agents, penetration agents, sequestering agents, fragrances, buffers, dispersing agents, conditioning agents, such as, for example, silicones, film-forming agents, preserving agents or opacifying agents.




Of course, a person skilled in the art will take care to choose the optional additional compound or compounds mentioned above so that the advantageous properties intrinsically attached to the dyeing composition according to the invention are not, or not substantially, detrimentally affected by the envisaged addition or additions.




The dyeing composition according to the invention can be provided in various forms, such as in the form of liquids, creams or gels, or in any other form appropriate for carrying out dyeing of keratinous fibers and in particular of human hair.




Another subject-matter of the invention is the use of the compounds of above formula (I) as coupler, in combination with at least one oxidation base, for the oxidation dyeing of keratinous fibers and in particular of human keratinous fibres, such as hair.




Another subject-matter of the invention is a process for the oxidation dyeing of keratinous fibres and in particular of human keratinous fibres, such as hair, employing the dyeing composition as defined above.




According to this process, at least one dyeing composition as defined above, is applied to the fibres, the colour being developed at acidic, neutral or alkaline pH using an oxidizing agent which is added only at the time of use to the dyeing composition or which is present in an oxidizing composition applied simultaneously or sequentially in a separate fashion.




According to a particularly preferred embodiment of the dyeing process according to the invention, the dyeing composition described above is mixed, at the time of use, with an oxidizing composition comprising, in a medium appropriate for dyeing, at least one oxidizing agent present in an amount sufficient to develop a colouring. The mixture obtained is subsequently applied to the keratinous fibres and is left to stand for 3 to 50 minutes approximately, preferably 5 to 30 minutes approximately, after which the hair is rinsed, washed with a shampoo, rinsed again and dried.




The oxidizing agent present in the oxidizing composition as defined above can be chosen from oxidizing agents conventionally used for the oxidation dyeing of keratinous fibres and among which may be mentioned hydrogen peroxide, urea hydrogen peroxide, alkali metal bromates, or persalts, such as perborates and persulphates. Hydrogen peroxide is particularly preferred.




The pH of the oxidizing composition including the oxidizing agent as defined above is such that, after mixing with the dyeing composition, the pH of the resulting composition applied to the keratinous fibres preferably varies between 3 and 12 approximately and more preferably still between 5 and 11. It is adjusted to the desired value by means of acidifying or basifying agents commonly used in dyeing keratinous fibres and as defined above.




The oxidizing composition as defined above can also include various adjuvants conventionally used in hair dyeing compositions and as defined above.
