Description

The subject of the present invention is a dyeing composition for keratin fibers, comprising at least one oxidation dye, at least one nonionic compound of the long-chain ether type of a polyoxyalkylenated fatty alcohol, at least one particular fatty alcohol and at least one less a chemical oxidizing agent.

The present invention also relates to a dyeing method using this composition, and a multi-compartment device, suitable for the implementation of this composition.

For a long time, many people have been trying to change the color of their hair and in particular to hide their white hair. One of the staining modes is so-called permanent staining or oxidation which uses dye compositions containing oxidation dye precursors, generally called oxidation bases. These oxidation bases are colorless or weakly colored compounds which, when combined with oxidizing products, can give rise to colored compounds by a process of oxidative condensation. It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or color modifiers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-aminophenols and meta-aminophenols. diphenols and certain heterocyclic compounds such as indole compounds. The variety of molecules involved in oxidation bases and couplers, allows to obtain a rich palette of colors. It is also possible to use direct dyes to bring particular reflections to the coloring obtained. These direct dyes are colored molecules and dyes, having an affinity for the fibers. For example, mention may be made of nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine or triarylmethane direct dyes. The permanent coloring processes thus consist in using with the dyeing composition an aqueous composition comprising at least one oxidizing agent. This oxidizing agent has several roles. The first is to cause a condensation of the oxidation dyes (bases, couplers) allowing the appearance of the color. The second is to partially degrade the melanin of the hair, which, depending on the nature of the oxidizing agent present, leads to a more or less pronounced lightening of the fibers. The oxidizing agent employed is usually hydrogen peroxide.

Thus, the compositions used in this type of process must be able to be easily mixed and the rheology of the resulting mixture must be such that it can be spread easily without flowing out of the zones to be colored once in place, and this for the duration treatment.

Moreover, the mixtures must result in homogeneous colorings between the tip of the hair and the root (we also say that they are not very selective), be chromatic and powerful. European Patent Application EP 1106167 describes oxidation dye compositions comprising, in addition to the dyes, a nonionic compound derived from a long-chain ether of a polyoxyethylenated fatty alcohol. These compositions represented an improvement over the existing compositions, not only in terms of viscosity and viscosity stability during the laying time on the hair, but also in terms of dyeing results.

However, we are still looking for better coloring in terms of results, including a better rise in color and better homogeneity of color. We are also looking for compositions with improved use qualities, especially in terms of ease of distribution on the hair and elimination during rinsing.

One of the objectives of the present invention is to provide compositions for staining human keratinous fibers such as the hair which do not have the disadvantages of existing compositions. These and other objects are achieved by the present invention which therefore relates to a coloring composition of keratinous fibers, in particular human keratinous fibers such as the hair, comprising: at least one oxidation dye; at least one nonionic ether of polyoxyalkylenated fatty alcohol of formula (I) R- (O-Alk) n OR '(i), in which: R denotes a saturated or unsaturated, linear or branched hydrocarbon radical, in C , o-C30, - R 'denotes a linear or branched, saturated or unsaturated hydrocarbon-based C 10 -C 30 radical which may be substituted with a hydroxyl radical, the hydroxyl radical being preferably located in the beta position of the ether function; n is an integer inclusive of between 1 and 100; and - Alk represents a linear or branched, preferably linear, (C1-C6) alkylene group such as ethylene or propylene, preferably ethylene; at least one fatty alcohol comprising at least 20 carbon atoms; at least one chemical oxidizing agent.

The subject of the invention is also a dyeing method using the abovementioned composition.

Finally, it relates to multi-compartment devices for implementing the composition of the invention. Thus, the use of the coloring composition of the invention leads to homogeneous and powerful colorations. These compositions are easily distributed on the hair and are easily removed by rinsing.

Other features and advantages of the invention will become more apparent upon reading the description and the examples which follow. In what follows, and unless otherwise indicated, the boundaries of a domain of values are included in this field. The human keratinous fibers treated by the process according to the invention are preferably the hair. Within the meaning of the present invention, and unless a different indication is given: the expression "inclusive" for a range of concentrations means that the range terminals fall within the defined range. The human keratin fibers treated by the process according to the invention are preferably the hair. The expression "at least one" followed by an ingredient is equivalent to the expression "one or more" ingredients. By "direct emulsion" is meant a mixture, microscopically heterogeneous, and macroscopically homogeneous, of two liquid immiscible liquids between them of oil-in-water type (HIE or O / W for oil in water). The emulsion is composed of an oily phase dispersed in an aqueous phase; "Emulsion" in the sense of the present invention is therefore true emulsions, to distinguish microemulsions, which are thermodynamically stable systems unlike true emulsions. The size of the droplets of the dispersed phase of the emulsions of the invention is preferably between 10 nm and 100 μm and preferably between 200 nm and 50 μm. This is the average diameter D (3.2) measurable, in particular using a laser granulometer. The direct emulsion may be prepared by conventional emulsion preparation methods, well known to those skilled in the art. By "oxidizing agent" or "chemical oxidizing agent" according to the invention is meant an oxidizing agent other than oxygen in the air.
