Description

COMPOSITION FOR COLORING OR LIGHTENING KERATINOUS FIBERS IN THE FORM OF MICROEMULSION BASED ON SPECIAL OIL (S), SOLVENT (S) HYDROTROPE (S) AND SURFACTANT (S).

The subject of the present invention is a composition (A) for dyeing or lightening keratinous fibers, such as the hair, in the form of a microemulsion comprising at least 0 of water; ii) at least one non-carbonylated oil; HO at least one liquid organic compound having a value of Hansen solubility parameter 6H greater than 0 and less than 16 MPa 1/2, the total content of organic compound (s) liquid (s) having a value of the parameter having a solubility of Hansen 6H greater than 0 and less than 16 M Pa 1/2 ranging from 0.5 to 35% by weight relative to the weight of the composition, iv) at least one surfactant and y) at least one compound selected from a) coloring agents chosen from direct dyes, oxidation dyes, and / or their mixtures; (b) chemical oxidizing agents; (c) basifying agents; d) and their mixtures.

This invention also relates to a process for dyeing or lightening keratinous fibers using such a composition, as well as a multi-compartment device comprising said composition.

Two major modes of staining human keratinous fibers, and in particular the hair, are known. Among the methods for staining human keratinous fibers, such as the hair, mention may be made of oxidation or permanent staining. More particularly, this coloring mode uses compositions comprising one or more oxidation dyes, or one or more oxidation dye precursors, usually one or more oxidation bases optionally associated with one or more couplers. In general, 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, make it possible to access, by a process of oxidative condensation, colored species which remain trapped inside the fiber. The oxidation dyeing processes therefore consist in using with these dyeing compositions a composition comprising at least one oxidizing agent, generally hydrogen peroxide, under alkaline pH conditions in the vast majority of cases. This oxidizing agent has the role of revealing the color, by an oxidative condensation reaction of the oxidation dyes with each other. 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. These bases and couplers are colorless or weakly colored compounds which, when combined with oxidizing products, can give rise to colored compounds by a process of oxidative condensation. The variety of molecules involved in the oxidation bases and couplers allows a rich palette of colors to be obtained. This type of oxidation coloring makes it possible to obtain permanent colorations. Most of the oxidation dyes used have sufficient aqueous solubility and there are now many coloring media adapted to receive them. However, the existing oxidation dye supports do not give complete satisfaction especially with respect to the power or the intensity of the colorations obtained or their chromaticity or their selectivity (color difference obtained between the zones more or less sensitized with a hair). The second mode of staining, called direct or semipermanent staining, comprises the application of direct dyes which are colored and colored molecules, having an affinity for the fibers, of natural or synthetic origin. Given the nature of the molecules used, these remain rather on the surface of the fiber and penetrate relatively little inside the fiber, compared to the small molecules of precursors of oxidation dyes. The direct dyes generally employed are chosen from nitrobenzene, anthraquinone, nitropyridine, azo, methine, azomethine, xanthene, acridine, azine or triarylmethane direct dyes. The chemical species used may be nonionic, anionic (acidic dyes) or cationic (basic dyes). Most of the direct dyes used have sufficient aqueous solubility and there are now many coloring media adapted to receive them. These compositions containing one or more direct dyes are applied to the keratinous fibers for a time necessary to obtain the desired coloration, and then rinsed. However, the resulting colorations are particularly chromatic but temporary or semi-permanent colorations because the nature of the interactions that bind the direct dyes to the keratin fiber, and their desorption of the surface and / or the core of the fiber are responsible for their low dyeing power and their poor resistance to washes.

This type of process does not require the use of an oxidizing agent to develop the coloring. However, it is possible to implement such an agent, in order to obtain a brightening effect with the coloring. We then speak of a direct or semi-permanent coloration in lightening conditions.

The methods of permanent coloring or semi-permanent staining in lightening conditions therefore require using, with the dyeing composition, an aqueous composition comprising at least one oxidizing agent, under alkaline pH dyeing conditions in the vast majority of cases.

The conventional processes for bleaching human keratin fibers consist in using an aqueous composition comprising at least one oxidizing agent. This oxidizing agent has the role of degrading the melanin of the hair, which, depending on the nature of the oxidizing agent and the pH conditions, leads to a more or less pronounced lightening of the fibers. Thus, for relatively low lightening, the oxidizing agent is generally hydrogen peroxide. When greater lightening is desired, it is customary to use peroxygenated salts, such as, for example, persulfates, in the presence of hydrogen peroxide. Conventionally, the lightening or coloring compositions may be in the form of emulsions or even nanoemulsions. However, these architectures may present problems of instability, in particular of "phase shift" i.e. a separation into two visually distinct phases with on one side the oily phase and on the other the aqueous phase. This problem of instability of the emulsion is increased in the case of emulsions (or nanonemulsions) rich in oil (s). One solution for improving the stability of these compositions may be to increase the concentration of emulsifier (s). However, a high concentration of emulsifiers (especially surfactants) can lead to a rough, adhesive or sticky, and in some cases lead to irritation or tingling of the skin, eyes and scalp. In addition to coloration, a high content of surfactants can slow down the color by the possible interactions between the dyes and these surfactants. In addition, nanoemulsions, which are thermodynamically unstable systems, generally require a significant energy input to be obtained. It is therefore sought to formulate compositions having improved properties, especially qualities of use, particularly in terms of texture, ease of mixing and / or ease of application and spreading on the hair. It is also sought to obtain compositions which are stable over time, in particular, which remain homogeneous and do not exhibit a phase shift problem, for example at the end of at least 1 month, or even 2 months at 45.degree. be prepared easily. It is also sought to obtain transparent or translucent compositions which are pleasant to use, in particular which do not present the problems of discomfort and / or of safety, in particular such as those mentioned above, and linked to the presence of a certain content. high in surfactants. Finally, it is sought to obtain compositions whose dyeing and / or lightening efficiency is improved, in particular making it possible to reduce the amount of active agents and / or composition required and / or the time of application of the composition to the fibers. to color or discolor. Finally, it is sought to obtain compositions which make it possible to obtain lightening and / or coloring properties of the more efficient keratin fibers, especially in terms of power, resistance to external attack, intensity, homogeneity and which are not very selective.

The Applicant has surprisingly found that it is possible to overcome the problems mentioned above by proposing a composition in the form of a microemulsion comprising a surfactant or a mixture of surfactants and at least one particular solvent chosen from the solvents of the higher Hansen parameter 6H. at 0 and less than 16 MPa 1/2 and an oily phase comprising at least one non-carbonylated oil.

In addition, the composition according to the present invention has very good qualities of use, and in particular a particularly pleasant texture.

In addition, it does not run and remains well located at the application points and spreads easily from the roots to the tips. The term "microemulsion" means a thermodynamically stable mixture, microscopically heterogeneous, and macroscopically homogeneous, two liquid substances immiscible with each other, such as an oily phase and an aqueous phase). The microemulsions may be of the oil-in-water type (O / W or 0 / VV for or in water), ie oil droplets solubilized in the form of direct micelles swollen in a continuous aqueous phase, or water-in-oil type (W / O or VV / O for water in or), that is to say water droplets solubilized in the form of inverse micelles inflated in an oily continuous phase, or alternatively bicontinuous type, that is, in the form of structures where water and oil are co-solubilized, water and oil being simultaneously considered to be the continuous phase or the dispersed phase.

Microemulsions are to be distinguished from nanoemulsions which are thermodynamically unstable dispersions of oil droplets or water within a continuous aqueous or oily phase. Microemulsions are formed by simple mixing of the various constituents, without the need for significant energy input. the microemulsion according to the invention has the advantage of being prepared cold, without significant energy input, which facilitates its industrial manufacture and, secondly, to be able to use heat-sensitive assets that can be difficult to incorporate in conventional emulsions or nanoemulsions when the process of manufacture requires a heating step capable of degrading them. In addition, the microemulsions generally have a particular microstructure formed of microdroplets whose size is such that the light passes through them without being diffused, so that the appearance of this composition is transparent or translucent whereas the appearance of a conventional emulsion is opaque.

In addition, the microemulsion according to the invention has the advantage of being stable, even when the quantity of oil present is high, in particular when it is greater than 5%, or even 10% or even 20% by weight relative to the weight of the composition, especially when it is desired to limit the content of surfactants. In addition, compared with a conventional emulsion or a nanoemulsion, the microemulsion according to the invention has the advantage of allowing better penetration of the active ingredients in the keratin fiber because of the small size of its microdroplets and therefore of constituting a best vector for assets. In addition, a microemulsion according to the invention may contain a larger quantity of active agents, and in particular active agents that are difficult to solubilize. In particular, this makes it possible to reduce the amount of active ingredients and / or dye composition required and / or the time of application of the composition to the fibers for coloring or bleaching. In the case where the microemulsion according to the invention is in the form of droplets dispersed in a continuous phase, the average size in number of the droplets of the dispersed phase of the microemulsions of the invention is preferably less than 100 nm, more preferably less than 50 nm, more preferably between 1 and 50 nm. The average particle size of the particles can be determined in particular according to the known method of quasi-elastic light scattering. As an apparatus usable for this determination, mention may be made of the BROOKHAVEN branded apparatus equipped with an SX 200 optical bench (with a 532 nm laser), and a BI 9000 correlator. This apparatus provides a measurement of the diameter. by means of photon correlation spectroscopy (or PCS: "Photon Correlation Spectroscopy") which makes it possible to determine the number average diameter from the polydispersity factor also measured by the apparatus.

The microemulsion can be prepared by conventional methods of preparing microemulsions, well known to those skilled in the art, in particular following the development of phase diagrams to know the formation domain of the microemulsion.

According to a particular embodiment of the invention, the microemulsion according to the invention has the advantage of being able to comprise a limited content of emulsifiers, and in particular surfactants, while remaining stable. Indeed, even after passing through a centrifuge, the microemulsion according to the invention spontaneously returns to its initial thermodynamic equilibrium at a given temperature.

Moreover, the microemulsion remains stable even after 2 months of storage at 45 ° C. Such a composition has the advantage of limiting the aforementioned drawbacks related to a very high concentration of emulsifiers. Preferably, the composition according to the invention comprises a total content of surfactants of between 0.1% and 30% by weight, preferably between 1 and 25% by weight, better still between 5 and 19% by weight relative to total weight of the composition.
