Description

B 08/2325 EN GD / JBL / ET OA 08539 Société Anonyme known as: L'ORÉAL Delicate coloring or bleaching composition of keratin materials comprising superabsorbent polymer fibers Invention of: M. Henri SAMAIN Deliable composition of coloring or bleaching of keratin materials The present invention relates to novel deleatic cosmetic compositions intended to modify the color of keratin materials, in particular keratinous fibers, in particular human keratin fibers such as the hair, preferably by coloring or bleaching of said materials. or keratinous fibers. In the hair field, two types of coloration can be distinguished. The first type of staining is permanent staining or oxidation staining which uses oxidation dye precursors, generally known as oxidation bases. These oxidation bases are colorless or weakly colored compounds which, combined with oxidizing products, give rise by a process of oxidative condensation to colored compounds. The shades obtained with these oxidation bases can also be varied by combining them with couplers or color modifiers.

The oxidation dyeing process consists in applying to the keratinous fibers oxidation bases or a mixture of oxidation bases and couplers with an oxidizing agent, such as hydrogen peroxide (or hydrogen peroxide), which is added at the time of use.

Generally, this process is carried out at an alkaline pH, in particular in the presence of ammonia, and makes it possible to obtain a dyeing and at the same time a lightening of the fiber, which in practice results in the possibility of obtaining a lighter final coloration than the original color. In addition, the lightening of the fiber has the advantageous effect of generating a solid color in the case of depigmented hair, and in the case of naturally pigmented hair, to bring out the color, that is to say the color. make more visible. The second type of staining is the semi-permanent or temporary staining, or direct staining, which uses dyes capable of providing the natural color of the hair, a more or less marked color change. These dyes are called direct dyes; they can be used with or without an oxidizing agent. In the presence of oxidizing agent, the coloring is called lightening and makes it possible to obtain a lighter color than the original color of the fibers; without an oxidizing agent, it is the classic non-lightening direct dyeing. These dyeing compositions must generally meet a certain number of requirements. They must have satisfactory dyeing properties, for example in terms of power, chromaticity, reduced selectivity, staining behavior, and be harmless toxicologically. These compositions must also be sufficiently stable and in particular their constituents must not have any incompatibilities between them. Thus, it is customary to use dye compositions comprising oxidation dyes or direct dyes for dyeing keratin materials, in particular keratin fibers such as the hair.

In US patent application 2008/0083419, it is known to employ nonwoven superabsorbent polymers, in the form of fibers, as solid supports for coloring compositions. These compositions do not disintegrate when they are applied to keratinous fibers.

However, the use of these basic stain compositions can be further improved in many aspects. To bleach hair, compositions containing hydrogen peroxide alone or in combination with persalts are generally employed.

These bleaching compositions are almost always in the form of a liquid of moderate viscosity and are most often difficult to apply.

Thus, one seeks compositions capable of modifying the color of keratin materials, in particular keratin fibers, especially human keratin fibers such as hair, which are easy and practical to use. In particular, the transfer of the dyeing or bleaching agent onto the keratin materials and in particular onto the keratin fibers must be easy. The compositions according to the invention must not flow and must remain well localized at the point of application, even when mixed with an oxidizing agent, during application or after application, especially when these compositions are deposited on the keratin materials. It is also desired to apply lesser amounts of composition compared to conventional liquid or semi-liquid coloring or decolourization compositions (more or less thickened liquids, gels, creams) for the same desired effect. In addition, in view of the uniformity of the coloring and discoloration supply, compositions with an original texture compared to those shown by the conventional compositions and which are stable and preferably compatible with the dyes or oxidizing agents employed are sought. in the field of coloring or bleaching of keratin materials, in particular keratinous fibers, especially human keratinous fibers such as the hair. In particular, we are interested in coloring compositions which, in addition, should not or little stain hands, clothes or scalp, especially when rubbing keratin materials or fibers treated with the hands or the skin. clothing, or when rinsing these compositions. The inventors have surprisingly discovered that the use of particular polymer fibers with absorbent properties in compositions for modifying the color of keratin materials, preferably keratinous fibers, in particular human keratin fibers such as hair, afforded access to novel compositions having the above-described advantages over conventional liquid or semi-liquid coloring or bleaching compositions.

Thus, according to a first aspect, the present invention relates to a deformable composition for modifying the color of keratin materials, preferably keratinous fibers, in particular human keratinous fibers such as the hair comprising: one or more superabsorbent polymers present in the composition fiber form, and one or more coloring agents and / or one or more oxidizing agents. It has been observed that these compositions are stable. They have a very high viscosity and are also endowed with a particularly original fibrous or cottony appearance compared with conventional dyeing compositions. The compositions according to the invention do not flow during the application or the pause step and allow a precise, easy and optimized application of the coloring agent (s) and / or oxidizing agent (s). In addition, the transfer of the coloring agent and / or the oxidizing agent onto the keratin materials is very easy, it does not require effort when applied to keratin materials.

When the compositions according to the invention are coloring compositions, it has been observed, moreover, that they advantageously retain the dyeing properties of conventional dyeing compositions and do not stain the scalp or hands very little or not at a time. possible contact with the treated materials or fibers, or during a possible rinsing. Consequently, these compositions can be used as a non-rinsed product without generating the usual disadvantages brought about by this type of application, such as staining problems when the treated keratin materials or fibers are rubbed. When these compositions are rinsed, they require only a short rinsing time compared to conventional liquid or semi-liquid dye compositions (gels, creams) which require a rinsing of at least 5 minutes and generally require 50 liters of water. or more, which in particular makes it possible to avoid staining problems.

The amount of composition deposited on the keratin materials or fibers can be optimized by successive deposits to obtain in particular the desired intensity, without excess. The use of the composition is therefore particularly economical and the amount of composition used is relatively small compared to the quantities required with conventional liquid or semi-liquid dye compositions. The present invention also relates to a process for modifying the color of keratin materials, in particular keratinous fibers, in particular human keratinous fibers such as the hair, in which one or more dyeing compositions according to the invention are applied to said keratinous materials, for a time sufficient to decolorize the keratin materials or to develop the desired coloration.

Another subject of the present application relates to a device with one or more compartments for modifying the color of keratin materials, in particular keratinous fibers, especially human keratinous fibers such as hair, containing in at least one of its compartments a or several compositions according to the invention. According to another aspect, the invention relates to the use for modifying the color of keratin materials, in particular keratinous fibers, in particular human keratinous fibers such as the hair, of at least one composition according to the invention.

Other features, aspects, objects and advantages of the invention will emerge even more clearly on reading the description and examples which follow. Unless otherwise indicated, the ranges of the ranges of values which are given within the scope of the present invention are included in these ranges. Delizeable composition means a solid composition at room temperature (about 25 ° C) and at atmospheric pressure (about 760 mm mercury), possibly deformable, which breaks up into particles by application or friction on the materials or keratinous fibers . The edible composition has a compact appearance and does not flow when the product is spilled. It is neither a gel nor a cream. By solid composition is meant a composition having a viscosity greater than 100 poise at a temperature of 25 ° C and a shear rate of 1 s-1. The viscosity is preferably evaluated with the aid of a viscometer, such as the THERMOELECTRON viscometer HAAKE RS1 (viscometer with plane cone geometry). The insoluble fibers of superabsorbent polymer considered according to the invention can be evenly or uniformly distributed in the composition. They are generally in such quantity that the composition is in the form of a solid or a deformable solid. In addition to a very original texture, the optionally deformable solid form of the compositions of the invention makes it possible to avoid sagging on application.

The solid texture of the product makes it possible to consume as little as possible, i.e., low deposited quantities adapted to the desired (de) coloration. By color modification is meant a change in the color perceptible to the eye of the keratin materials or fibers, whose color variation before and after staining or discoloration expressed by DE, is preferably greater than or equal to 2. Colorimetric measurements can be made using the Konica Minolta CM-2600d spectrocolorimeter in the CIE L * a * b * system. In this system, L * represents the intensity of the coloration obtained. The lower the value of L *, the more intense the coloration obtained. The chromaticity is measured by the values a * and b *, a * indicating the value on the green / red color axis and b * indicating the value on the blue / yellow color axis. We measure AE from the formula: ## EQU1 ## in which: L *, a * and b *, represent the parameters of the materials or keratinous fibers after staining or discoloration and Lo *, ao * and bo * represent the parameters of natural or unbleached natural keratin materials or fibers.

Thus, the higher the value of AE, the greater the variation in the color is and therefore visible. "Physiologically acceptable" means a medium compatible with the application on the body of a living being, in particular of a human being, in particular on its keratinous fibers, in particular the hair. SUPERABSORBENT POLYMER According to the present invention, the term "superabsorbent polymer" is understood to mean a polymer capable, when in the dry state, of spontaneously absorbing at least 20 times its weight of aqueous fluid, in particular water and especially water. 'distilled water. Such superabsorbent polymers are described in the book "Absorbent Polymer Technology, Studies in Polymer Science 8" by L. BRANNON-PAPPAS and R. HARLAND, Elsevier edition, 1990.

These polymers have a high capacity for absorption and retention of water and aqueous fluids. After absorption of the aqueous liquid, the polymer particles so imbibed with aqueous fluid remain insoluble in the aqueous fluid and retain their individualized particulate state.

Thus, the superabsorbent polymer can have, in the dry state, a water absorption capacity ranging from 20 to 2000 times its own weight (ie 20 g to 2000 g of water absorbed per gram of absorbent polymer), preferably from 30 to 1500 times, and better 50 to 1000 times. These water absorption characteristics are defined under normal conditions of temperature (25 ° C) and pressure (760 mm Hg or 100,000 Pa) and for distilled water. The value of the water absorption capacity of a polymer can be determined by dispersing 0.5 g of polymer (s) in 150 g of a water solution, while waiting for 20 minutes, filtering the non-aqueous solution. absorbed on a 150 m filter for 20 minutes and weighing the unabsorbed water. The superabsorbent polymer fibers generally have, in the dry state, a number average length greater than 0.5 mm, preferably greater than or equal to 1 mm, in particular ranging from 1 mm to 100 mm, in particular ranging from 1 to 65 mm, and more preferably 5 to 10 mm. The term "fiber length" means the largest dimension of these fibers. In the dry state, the fibers generally have a number average width ranging from 1 to 100 m, in particular from 5 to 80 m, more preferably from 10 to 60 m, for example a width of about 30 m. The width may correspond to the diameter of the fiber, especially when the fiber has a substantially circular section. In the dry state, the superabsorbent polymer fibers preferably have an aspect ratio (length / width) of from 50 to 10,000, preferably from 50 to 2,500, more preferably from 75 to 1,000, and most preferably from 100 to 10,000. 500, for example about 200 In the presence of water, these fibers swell. The superabsorbent polymer may be partially or completely swollen in the composition according to the invention.

The superabsorbent polymer can be introduced into the composition in dry form. The polymer may also be introduced in a partially inflated state. To do this, the superabsorbent polymer can be swollen in a portion of the physiologically acceptable medium of the composition, especially water, before being introduced into the composition. In the composition according to the invention, the fibers preferably have a number-average width ranging from 5 to 500 m, preferably from 25 to 400 m, more preferably from 50 to 300 m and for example a width of about 150 m. Thus, when passing from dry to wet in the composition, the fibers may have a width increasing by a factor of about 5. In the composition, the fibers may have an aspect ratio ranging from 1 to 2000, preferably from 2 to 200, more preferably from 15 to 150, and more preferably from 20 to 100 and for example from approximately 40. Thus, by passing from the dry state to the wet state, the ratio appearance decreases. In particular, the ratio (aspect ratio to swollen state / aspect ratio in the dry state) can range from 0.004 to 1, preferably from 0.008 to 0.75, more preferably from 0.01 to 0.50, for example, be about 0.2. The superabsorbent polymer according to the invention may be anionic, cationic or nonionic and is preferably nonionic or anionic. This superabsorbent polymer is different from a biopolymer and, in particular, is a synthetic polymer. By "synthetic polymer" is meant polymer obtained chemically or by production in an organism of the elements necessary for its production. As examples of superabsorbent polymers, there may be mentioned the polymers resulting from the polymerization with partial crosslinking of water-soluble ethylenically unsaturated monomers, such as acrylic or vinyl polymers, in particular crosslinked and partially or completely neutralized polyacrylates. As superabsorbent polymer leading to fibers in the compositions of the invention, mention may be made of the products referenced OASIS 101 3 mm or OASIS SUB 250 MICRON or OASIS 121/6/10 ABSORBENTS offered by the company TECHNICAL based on an acrylate copolymer crosslinked partially neutralized and whose average respective lengths of fibers in the dry state are of the order of 3 mm, 250 m and 6 mm.

The composition according to the invention preferably comprises from 1 to 40% by weight, in particular from 5 to 25% by weight, and more preferably from 7 to 15% by weight of superabsorbent polymer (s), in particular in the form of of fibers, expressed in the dry state and relative to the total weight of the composition. Advantageously, this amount can also be adjusted to confer an original texture as mentioned above to the composition and in particular to endow it with a fibrous appearance.

Of course, those skilled in the art will take care to choose the optional additional compounds or compounds mentioned above, so that the advantageous properties intrinsically attached to the composition according to the invention are not, or not substantially impaired by the addition or additions envisaged. In particular, the compositions of the invention must remain deleterious. The present invention also relates to a process for modifying the color of keratinous substances, in particular keratinous fibers, in particular human keratinous fibers such as the hair, comprising the application to said keratin materials of one or more compositions according to the invention such as defined above, of identical or different formulation for a time sufficient to decolorize the keratin materials or to develop the desired coloration.

Preferably, a total amount of composition according to the invention ranging from 2 to 5 grams (g) is used, typically for 40 to 100 g of keratin fibers. An application of 1 g of composition for 20 g of keratin fibers is therefore generally sufficient to modify the color of the keratinous fibers. For keratin materials, an application of 1 g of composition per 400 cm 2 of skin makes it possible to obtain a change in the color of the keratin materials.

Among the processes according to the invention, one distinguishes staining (oxidation, direct or direct lightening) methods using one or more coloration compositions (oxidation or direct) according to the invention in the presence or absence of oxidizing agent (s) and bleaching processes using one or more bleaching compositions according to the invention. When the process according to the invention is a process for the oxidation dyeing or lightening direct dyeing of the keratin materials or fibers, one or more oxidizing agents, such as those defined above, are generally used to reveal or lighten the color respectively. In the latter case, two embodiments are distinguished. According to a first embodiment, the oxidizing agent (s) may be contained as a mixture in one or more oxidation dyeing compositions according to the invention or one or more direct dyeing compositions according to the invention used to carry out a lightening direct dyeing. as envisaged above. This mixture can be applied one or more times. To minimize possible interactions with the coloring agent (s), it may be advantageous to add the oxidizing agent (s) at the time of use in the oxidation dyeing composition according to the invention or coloring composition. direct according to the invention used to perform a direct lightening dyeing. According to another embodiment, the oxidizing agent (s) may be applied directly to the keratinous substances or fibers independently of the oxidation dyeing composition (s) according to the invention or independently of the direct dyeing composition (s) according to the invention. invention used to make a direct lightening dye. It can be applied before, after or at the same time as the oxidation dye composition (s) according to the invention or the direct dyeing composition (s) according to the invention used for carrying out a direct lightening color. In particular, they may be applied as such in the form of an oxidizing composition containing them, or in the form of a bleaching composition. according to the invention, that is to say a crumbly composition comprising one or more superabsorbent polymers in the form of fibers and one or more oxidizing agents. In the latter case, the bleaching composition may be prepared by contacting the oxidizing agent (s) with the other ingredients of the bleaching composition at the time of use, in order to limit the risks of interactions between the oxidizing agent (s). and said ingredients. The process according to the invention, in particular the staining or decolouration process, can be carried out as described below. After (each) application of the composition (s) according to the invention, it can be left paused or not. The exposure time then varies preferably from 5 minutes to 1 hour, and more preferably from 15 minutes to 1 hour. The treated keratin materials or fibers may then be rinsed with water, optionally washed with a standard detergent composition, such as shampoo and rinsed again with water, before being optionally dried. Another method according to the invention is to scrub the hair, then let dry, without rinsing. The rinsing time is preferably less than or equal to one minute. One to three liters of water is usually enough. The compositions according to the invention are therefore more easily eliminated compared to conventional lightening or direct dyeing or bleaching dyeing compositions which require a longer rinsing time and a larger amount of rinsing water.

In particular, when said keratin materials, in particular keratin fibers, are not rinsed, the dyeing (direct or direct lightening) method according to the invention has the advantage of not staining or staining very little. compared to conventional coloring products, even when rubbing skin or hair. The coloring processes according to the invention have the advantage, in addition to being non-messy, of being able to determine the intensity of the desired coloration by applying one or more times the dye composition to the keratinous materials or fibers to be dyed. To obtain a more intense coloring, it is thus possible to apply several times the dye composition on the materials or fibers by friction, without generating overcoats due to the application of an excessive amount of the composition on the treated materials or fibers. The use of the dye compositions according to the invention is therefore optimized according to the desired effect. For example, it is possible to apply to the zones of the keratin materials or fibers to be treated a first coloring composition according to the invention and then, possibly after a laying time, a second coloring composition according to the invention comprising as coloring agent a coloring agent identical to or different from that contained in the first staining composition for modifying or enhancing the color of the colored keratin materials after application of the first staining composition. The order of application of the first and second coloring compositions can be reversed. When carrying out the processes according to the invention, as defined above, one or more different treatment agents for the coloring agents, the oxidizing agents contained in the compositions of the invention may be added to the composition. staining or discoloration according to the invention, possibly just at the time of use, or may be carried out from a treatment composition the (s) containing applied before, during or after the application of the composition according to the invention.

When the treatment agent is added during the application of the composition according to the invention, then the treatment agent may be chosen from additional oxidizing agents, additional couplers, additional pH adjusting agents, dyes additional agents, conditioners and styling agents such as, for example, anionic, amphoteric or nonionic resins, gels (polysaccharides or anionic gels) or waxes. "Additional compound" means a compound other than those included in the composition according to the invention and defined above. In particular, when it is desired to customize the color beyond the expected color with the application of the composition according to the invention alone, one or more additional dyes different from those used as treatment agent are preferably chosen. included in the composition according to the invention. The user can customize his color according to his desires. When the treatment agent is added before or after application of the composition according to the invention, then the treatment agent may be chosen from activators such as metal salts, oxidizing agents, mordancers and dyes other than those included in the composition according to the invention. The composition according to the invention can be applied to keratin materials, in particular keratinous fibers such as hair, dry or wet. When the application is carried out on keratinous fibers, the treated keratin fibers may be brought into contact with a heat source or any other activation system such as ultrasound. When the application is carried out on the skin, the treated keratin material may be brought into contact with a heat source. Another subject of the invention relates to a device with one or more compartments for modifying the color of keratin materials, in particular keratin fibers, in particular human keratinous fibers such as the hair, containing in at least one of its compartments. one or more compositions according to the invention, that is to say one or more decomposable compositions comprising one or more superabsorbent polymers in the form of fibers and one or more coloring agents and / or one or more oxidizing agents, the one or more compartments; containing the composition or compositions according to the invention comprising one or more openings in order to be able to apply said composition or compositions to keratin materials. The opening or openings of said device generally have a size of at least 5 cm, preferably 5 to 10 cm. By "size" is meant the maximum measurable distance between two points of the opening. The different ingredients of the final composition according to the invention applied to the keratin fibers may be contained in the same compartment or in different compartments of the device according to the invention. When the device is used for coloring keratin materials or fibers, it comprises at least one coloring composition according to the invention. This is called a coloring device according to the invention. When the device is used for bleaching keratin materials or fibers, it comprises at least one bleaching composition according to the invention. This is called discoloration device according to the invention. The device according to the invention may comprise a single composition according to the invention, for example in a device with a compartment such as a petri dish. When the device according to the invention comprises at least two compositions of different formulation, provided that at least one of them is a delfittable composition according to the invention, it is called a heterogeneous device. In such a heterogeneous device, it is therefore possible to define different zones. "Zone" means a part or the whole of a compartment comprising a composition. The heterogeneous device may then comprise two, three or more different zones. Figures 1 to 3 illustrate a view of the surface applied to the keratin materials of heterogeneous devices according to the invention comprising from 2 to 3 zones.

By way of example of a heterogeneous device that may be used, there may be mentioned a device having two zones each corresponding to a composition 1 and 2 of different formulation, as represented in FIG. 1 or 2. In a first embodiment, the composition 1 is a dye composition according to the invention and the composition 2 is a dye composition according to the invention comprising as dyeing agent one or more dyes different from the dyeing agent or the mixture of coloring agents used in the composition 1. The coloring agents included in the compositions 1 and 2 may be compatible or not. By non-compatible means compounds that can react with each other. Preferably, the coloring agents of compositions 1 and 2 are compatible. In particular, compositions 1 and 2 may or may not comprise one or more reducing agents. Advantageously, it will be avoided to use together a composition comprising one or more direct dyes and a reducing coloring composition because of the possible problems of incompatibility. In a second embodiment, the composition 1 is an oxidation dyeing composition according to the invention containing one or more oxidation bases, and the composition 2 is a delizable composition comprising one or more superabsorbent polymers in the form of fibers such as as for example those used in the compositions of the invention, and one or more couplers. In particular, compositions 1 and 2 may or may not comprise one or more reducing agents. In a third embodiment, the composition 1 is an oxidation dyeing composition according to the invention comprising one or more oxidation bases and moreover one or more couplers, and the composition 2 is a bleaching composition according to the invention .

Compositions 1 and 2 may be of identical formulation to the compositions 1 and 2 of the heterogeneous device examples having two different zones described above. The composition 3 is a "fungible" interlayable composition comprising at least one superabsorbent polymer in the form of fibers which may be chosen for example from those used in the compositions of the invention. The term "intercalary composition" means a composition which is positioned in the heterogeneous dyeing device according to the invention so as to separate two neighboring compositions of different formulation. The intermediate composition may further comprise one or more active agents chosen from dyes such as oxidation dyes, direct dyes and / or mixtures and the salts of these compounds, and oxidizing agents such as H 2 O 2. Alternatively, when it does not include any asset, it is called a neutral composition. In this case, the neutral composition separating two compositions of different formulation makes it possible to improve the seal between the two separate compositions.

In the heterogeneous device according to the invention, the compositions of different formulation and thus the different zones may be adjacent or superimposed. These zones can have identical or different shapes.

By "adjacent zone" is meant an area placed next to another non-overlapping zone. By "superimposed area" is meant an area covering at least a portion of another area. By way of example of a heterogeneous device in which the zones are adjacent, there may be mentioned a device having two or three zones as previously described and illustrated in FIGS. 1 to 3, and in which the zones are positioned side by side. In particular, in the particular two-zone embodiments as described above, the zones 1 and 2 may have the same shape. In other particular embodiments with two or three zones as described above, zone 1 may be included a multitude of times in zone 2, for example, or vice versa. These embodiments are illustrated in FIGS. 2 and 3. By way of example of a heterogeneous device in which the zones are superimposed, there may be mentioned a device having two, three or more different zones as described above and illustrated by the figures 1 to 3, and wherein the zones 1, 2 and / or 3 are superimposed. In particular, it is possible to use a three-layer heterogeneous device having three zones 1, 2 and 3 superimposed so that zone 1 covers zone 3 which itself covers zone 2 and such that zone 1 is constituted of a dye composition according to the invention, the zone 3 of a deleterious neutral composition, and the zone 2 of a bleaching composition according to the invention preferably comprising as oxidizing agent hydrogen peroxide.

The surface 4 of FIG. 4 corresponds to the surface of the device placed in contact with the keratin materials or fibers. In addition, one or more physical boundaries such as a wall, may delimit two or more different areas. Thus, in particular embodiments with two or three zones as described above, zones 1, 2 and 3 may be separated by one or more walls, which may be permeable. These walls generally correspond to the walls of the compartments of the heterogeneous device and may preferably be removable in order to obtain, by mixing, a final coloring or bleaching composition to be applied to the keratin materials or fibers. Some compartments may also be empty in order to introduce any additives before using the device according to the invention. It is also possible to use a membrane or a plug as a wall. As an example of a removable wall device that may be used, there may be mentioned a device, as represented in FIG. 5, in which a first compartment 7 contains at least one dye composition according to the invention as defined above and a second compartment 6 contains at least one oxidizing agent and / or an alkaline agent, the two compartments being separated by a removable wall 8 to be removed at the time of use.
