Description

B12-0412EN 1 COLORING PROCESS USING A MIXTURE COMPRISING A PARTICULAR CATIONIC POLYMER OBTAINED FROM AN AEROSOL DEVICE, AND DEVICE The subject of the present invention is a process for dyeing keratin fibers, such as hair using a mixture comprising one or more cationic polymers, whose cationic charge density is greater than 4 milliequivalents per gram (meq / g), said mixture being obtained from two compositions, at least one of which is packaged in a container pressurized, as well as an appropriate device for the implementation of this method. Among the methods for staining human keratinous fibers, such as the hair, mention may be made of oxidation or permanent staining. More particularly, this mode of staining uses one or more oxidation dyes, usually one or more oxidation bases possibly associated with one or more couplers. In general, the oxidation bases are chosen from ortho- or para-phenylenediamines, ortho- or para-aminophenols as well as heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds which, combined with oxidizing products, allow access to colored species. Very often, the shades obtained with these oxidation bases are varied by combining them with one or more couplers, 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 molecules involved in the oxidation bases and couplers allows a rich palette of colors to be obtained. The permanent coloring processes therefore consist in using with the dyeing composition an aqueous composition comprising at least one oxidizing agent such as hydrogen peroxide, under alkaline pH conditions in the vast majority of cases. The alkaline agent conventionally used is ammonia or other alkaline agents, such as alkanolamines. The coloring compositions may be in various forms such as lotions, gels, emulsions, creams or foams. These compositions, in particular compositions comprising oxidation dyes, are obviously sensitive to oxidation and therefore contain reducing agents or antioxidants. This protective action against oxidation is further enhanced by the inert atmosphere that is sometimes used in the packaging of these compositions. The difficulty encountered with this type of compositions results precisely from their sensitivity to oxidation. Indeed, during their use, they are placed in contact with the oxygen of the air and this then requires that they be used quickly. Otherwise, the compositions become unusable after storage and are lost. There are in the field of hair dyeing, compositions which are packaged in pressurized containers and which make it possible to prevent the composition from coming into contact with the air during their use, as is described, for example, in the documents US 2010/0236570 or FR 2 048 629. However, the coverage of hair, especially white hair, still needs to be improved as well as the galenic quality of the product from the pressurized container. There is a constant need to develop oxidation dyeing compositions, in particular in the form of foam, which are easy to prepare and apply, which remain sufficiently stable over time and while maintaining effective dyeing properties, especially in terms of coverage. hair, more particularly white, but also intensity, homogeneity perfectly and chromaticity of the coloring obtained. This and other objects are achieved by the present invention which relates to a process for dyeing keratinous fibers, wherein a mixture obtained from: - a dyeing composition comprising at least one dye precursor is applied to said fibers; oxidizing composition, and - an oxidizing composition comprising at least one chemical oxidizing agent, - at least one of the compositions being delivered from a pressurized device, - mixing the two compositions comprising one or more cationic polymers, whose cationic charge density is greater than 4 milliequivalents per gram (meq / g).

It also relates to a device suitable for carrying out the process according to the invention, comprising: a first container containing a coloring composition comprising at least one oxidation dye precursor, and a second container containing an oxidizing composition comprising at least one oxidation dye precursor comprising: at least one chemical oxidizing agent, at least one of the containers being pressurized, preferably the two containers being pressurized, means for delivering the compositions; the mixture of the two compositions comprising one or more cationic polymers, whose cationic charge density is greater than 4 milliequivalents per gram (meq / g). Preferably, the composition used in the process according to the invention is in the form of a foam which is particularly pleasant to apply. It has a light and airy texture, which makes it particularly pleasant to use. The qualities of the foam are sufficiently persistent over time to allow application of the product of homogeneous color and without sagging.

The composition of the invention makes it possible to retain dyeing properties such as the power of color, resistance to external agents (shampoos, perspiration, light) and selectivity, and especially the coverage of white hair. Other characteristics and advantages of the invention will emerge more clearly on reading the description and examples which follow. In what follows, and unless otherwise indicated, the boundaries of a domain of values are included in this field. The term "at least one" associated with an ingredient in the composition means "one or more". The terms oxyalkylenated, oxyethylenated, oxypropylenated, glycerol, respectively cover mono- or polyoxyalkylenated compounds, oxyethylenated, oxypropylenated, glycerolated unless otherwise specified. Unless otherwise indicated, the contents of the ingredients present in the compositions are indicated without taking into account the propellant content (s).

The cationic charge density of a polymer corresponds to the number of moles of cationic charges per unit mass of polymer under the conditions where it is totally ionized. It can be determined by calculation if we know the structure of the polymer, that is to say the structure of the monomers constituting the polymer and their molar or weight proportion. It can also be determined experimentally by the Kjeldahl method, generally at a pH of about 7 at room temperature. The cationic polymers having a cationic charge density greater than 4 meq / g, usable in accordance with the present invention, may be chosen from all those already known per se as improving the cosmetic properties of the hair treated with compositions, namely in particular those described in the patent application EP-A-0 337 354 and in the French patent applications FR-A2 270 846, 2 383 660, 2 598 611, 2 470 596 and 2 519 863.
