Description

Device for dispensing a product for coloring and / or lightening keratinous fibers comprising a cationic polymer

The subject of the present invention is a device for dispensing a product for dyeing and / or lightening keratinous fibers comprising compositions A and B, as well as a dyeing method implementing said device. It also relates to a kit comprising said device and a composition comprising a conditioning agent.

Among the methods for staining human keratinous fibers, such as the hair, mention may be made of oxidation or permanent staining. More particularly, this staining mode 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 containing the oxidation dyes 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 may be chosen from other alkaline agents, such as alkanolamines.

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.

In the field of hair dyeing, there exist alkaline, in particular coloring, and oxidizing compositions which are packaged separately in the same pressurized container and which make it possible to prevent the composition from coming into contact with the air during their use. . These compositions may be in the form of foam or cream.

However, the power of the coloring as well as the coverage of the hair, in particular white hair, still need to be improved as well as the rheological properties of the product (s) resulting from the pressurized container, in particular with regard to the ease mixing of the alkaline and oxidizing compositions, the homogeneity of the mixture and the quality of application on the keratinous fibers (in particular with regard to the wetting, the adhesion to the roots and the ease of elongation of the mixture on long strands of hair).

There is a constant need to develop devices for delivering coloring and / or lightening compositions having good use qualities such as ease of application and rinsability, which remain sufficiently stable over time, while retaining effective dyeing properties, especially in terms of coverage of hair, more particularly white, but also intensity, homogeneity, chromaticity and selectivity of the coloring obtained, with otherwise good cosmetic properties, the objective of the present invention is therefore to provide coloring and / or lightening compositions found in particular in the form of cream or gel, having good quality of use, in particular mixing and application, while having dyeing performance and / or high lightening.

This and other objects are achieved by the present invention which therefore relates to a device for dispensing a product for staining and / or lightening keratinous fibers consisting of a container comprising: i) at least two compartments a and b separated from each other, the compartment comprising a composition A comprising at least one alkaline agent and optionally at least one coloring agent, the compartment b comprising an oxidizing composition B comprising at least one chemical oxidizing agent; one and / or the other of the compositions of the two compartments comprising at least one cationic polymer having a cationic charge density greater than or equal to 6 meq / g, ii) a distribution means provided with at least one dispensing orifice , in communication with the compartments a and b, for simultaneously delivering the compositions A and B, in the mixed or separated state.

It also relates to a process for lightening and / or staining human keratin fibers using this device.

More specifically, the subject of the invention is a process for lightening and / or coloring human keratin fibers in which a composition A comprising at least one alkaline agent and optionally at least one coloring agent and a composition is applied to said fibers. B comprising at least one chemical oxidizing agent; one and / or the other of the two compositions comprising at least one cationic polymer having a cationic charge density greater than or equal to 6 meq / g, the compositions A and B being packaged in a device consisting of a container, preferably pressurized, comprising at least two compartments a and b separated from one another, the compartment comprising composition A and compartment b comprising composition B, the device comprising dispensing means provided with at least one orifice distribution, in communication with the compartments a and b, to deliver the compositions A and B simultaneously.

The device and the method of the invention make it possible to obtain good lightening and / or dyeing properties on keratinous fibers, and in the case of coloring in particular a powerful, intense and / or chromatic coloration, resistant to external agents (shampoos , perspiration, light), homogeneous, and not very selective.

The device comprising the compositions also leads to good qualities of use, in particular the application of compositions A and B is easy and the distribution is homogeneous along the keratinous fibers.

The device and method of the invention also lead to good cosmetic properties, especially in terms of detangling, flexibility and softness of the hair [

The mixture of compositions A and B rinses easily after the pause time.

In addition, the compositions A and B used in the dyeing and / or lightening process according to the invention are easily mixed before being applied to the keratinous fibers or directly to the keratinous fibers during simultaneous application. compositions A and B on the hair.
