Description

Title of the invention: Composition for lightening keratin fibers and method for lightening keratin fibers using this composition Technical field of the invention

[0001] The present invention relates to a composition for lightening keratin fibers comprising at least one (bi)carbonate, at least one silicate, at least one fatty acid and at least one fatty substance other than fatty acids, as well as a method for lightening keratin fibers using this composition. Context of the invention

[0002] When a person wants to change their hair color, especially when they want to achieve a lighter color than their original color, it is often necessary to first lighten or bleach the hair. To do this, lightening or bleaching products are used.

[0003] Hair lightening is assessed by the height of tone which characterizes the degree or level of lightening. The notion of "tone" is based on the classification of natural shades, a tone separating each shade from the one which immediately follows or precedes it. This definition and the classification of natural shades is well known to hairdressing professionals and published in the book "Sciences of hair treatments" by Charles ZVIAK 1988, Ed. Masson, pp.215 and 278.

[0004] Tone heights range from 1 (black) to 10 (light blond), with one unit corresponding to one tone; the higher the number, the lighter the shade.

[0005] It is known to lighten or bleach hair with lightening or bleaching compositions containing at least one chemical oxidizing agent, in alkaline pH conditions in the vast majority of cases. This oxidizing agent has the role of degrading the melanin in the hair, which, depending on the nature of the oxidizing agent present 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, particularly when the treated hair is dark, persulfates are usually used in the presence of hydrogen peroxide.However, the lightening obtained by the action of such a combination is not always satisfactory because the hair is obtained with unattractive yellow and / or orange highlights, which complicates subsequent coloring by limiting it to obtaining warm tones. In addition, lightening compositions based on persulfates can lead to a degradation of the quality of the fiber.

[0006] Furthermore, persulfate-based compositions are generally in the form of a powdery composition which is mixed with an aqueous oxidizing composition comprising hydrogen peroxide before application to the hair. Mixing the two compositions is therefore also not easy. This results not only in a relatively long mixing time but also in difficulties in obtaining a homogeneous mixture or even in difficulties in applying the mixture obtained to the hair. The mixture can in fact be difficult to distribute homogeneously over the entire head of hair, in particular on curly or frizzy hair, which can lead to unwanted non-uniform lightening performance.

[0007] Furthermore, persulfate-based compositions are generally not chemically compatible with the presence of oxidation dyes and / or direct dyes in order to be able to bleach the hair fiber and color it in a single step. Thus, when it is desired to simultaneously bleach and color keratin fibers, a two-step process is generally used with a first step of bleaching the keratin fibers followed by a second step of coloring the keratin fibers using a coloring composition comprising one or more direct dyes and / or one or more oxidation dyes.

[0008] Thus, there is a real need to develop a composition which makes it possible to obtain effective lightening of keratin fibers, in particular dark keratin fibers, with better neutralization of yellow and / or orange reflections. Such a composition must also be more respectful of the quality of the fibers, in particular by minimizing their degradation and present very good qualities of use, in particular by being easy to mix with an aqueous composition of hydrogen peroxide before use, the resulting mixture also being easy to apply to the keratin fibers. Furthermore, such a composition must also be compatible with the presence of direct and / or oxidation dyes in order to obtain a good color build-up, powerful, natural and chromatic colors and also make it possible to achieve a wider range of colors.Finally, the formulation of environmentally friendly cosmetic products, i.e. those whose design and development take environmental issues into account, is becoming a major concern in helping to meet global challenges. It is therefore essential to offer more sustainable compositions that will help to address these environmental challenges.

[0009] The applicant has surprisingly discovered that all or part of these objectives can be achieved by the composition according to the present invention. Summary of the invention

[0198] Amphoteric associative polymers according to the invention are for example described and prepared in patent application WO 9844012.

[0199] Among the amphoteric associative polymers according to the invention, acrylic acid / (meth)acrylamidopropyl trimethyl ammonium chloride / stearyl methacrylate terpolymers are preferred.

[0200] The non-ionic associative polymers which can be used according to the invention are preferably chosen from:

[0201] (a) copolymers of vinyl pyrrolidone and hydrophobic monomers with a chain fat, of which we can cite as examples:

[0213] Preferably, the polyurethane polyethers comprise at least two lipophilic hydrocarbon chains, having from 6 to 30 carbon atoms, separated by a hydrophilic sequence, the hydrocarbon chains possibly being pendant chains or chains at the end of a hydrophilic sequence. In particular, it is possible for one or more pendant chains to be provided. In addition, the polymer may comprise a hydrocarbon chain at one end or at both ends of a hydrophilic sequence.

[0214] Polyether polyurethanes can be multi-block, in particular in triblock form. The hydrophobic blocks can be at each end of the chain (for example: triblock copolymer with hydrophilic central block) or distributed both at the ends and in the chain (multi-block copolymer for example). These same polymers can also be in graft or star form.

[0215] Non-ionic fatty chain polyurethane polyethers may be triblock copolymers whose hydrophilic sequence is a polyoxyethylenated chain comprising from 50 to 1000 oxyethylenated groups. Non-ionic polyurethane polyethers comprise a urethane bond between the hydrophilic sequences, hence the origin of the name.

[0216] By extension, non-ionic fatty chain polyurethane polyethers also include those whose hydrophilic sequences are linked to the lipophilic sequences by other chemical bonds.

[0217] As examples of non-ionic fatty chain polyurethane polyethers which can be used in the invention, it is also possible to use Rhéolate 205® with urea function sold by the company RHEOX or even Rhéolates® 208, 204 or 212, as well as Acrysol RM 184®.

[0230] Preferably, the composition (A) according to the invention further comprises one or more non-associative polysaccharides, which are therefore different from the associative polymers above.

[0231] In the present invention, the term "polysaccharide" means a polymer consisting of sugar units. The term "sugar unit" means an oxygenated hydrocarbon compound which has several alcohol functions, with or without an aldehyde or ketone function, and which comprises at least 4 carbon atoms. The sugar units may optionally be modified by substitution, and / or by oxidation and / or by dehydration.

These treatments make it possible to produce polymers which may be, in particular, non-ionic, anionic or amphoteric.

[0235] In particular, guar gums, carob gums, starches and celluloses can be modified / treated.

[0236] The guar gums that can be used according to the invention can be modified by C1-C6 (poly)hydroxyalkyl groups.

The hydroxyalkylation rate preferably varies from 0.4 to 1.2 and corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functions present on the guar gum.
