    The request relates to the technical field of the maintenance of keratin materials, in particular human hair. The subject of your request relates to cosmetic agents containing at least one starch particle containing a pigment, at least one special anionic polymer and at least one propellant. In addition, the present application relates to a hair washing process using these agents as well as the use of these agents for the maintenance of keratin fibers.
    The washing of keratin fibers is generally carried out under the combined effect of water, soap and a mechanical action on the fibers. So, for example, when washing the hair, a shampoo containing a surfactant is first applied to your damp hair and then massaged on it. If the hair is then rinsed with water, the impurities removed from the hair, dissolved by water, shampoo and / or mechanical action are rinsed and the hair is cleaned in this way.
    If there is no water available for cleaning the hair or if conventional hair washing is not possible due to lack of time, the alternative to cleaning the hair with water is to use a dry shampoo.
    Dry shampoos contain, as an essential active material, a carrier material in the form of particles, which, due to its adsorption properties, is capable of binding on the impurities present on the hair or on the scalp. , such as fats or sebum. In particular, if necessary modified starches are used as support materials. If the hair is combed or brushed after applying the dry shampoo, the absorbed impurities are also removed from the hair with the powdery carrier material.
    Dry shampoos are preferably in the form of an aerosol spray. In the case of the corresponding products, the powder in suspension in a liquid phase is sprayed onto the hair by means of a propellant.
    Dry shampoos that are not completely removed from the hair cause a gray veil to form or adhere to the hair in the form of visible particles. These two effects are among the main disadvantages of using dry shampoos. As a solution to this technical problem, the state of the art has proposed the use of a combination of starch and clays as a support material in the form of particles. However, this technical solution has proved far from ideal. On the one hand, the problem of gray veil formation cannot be completely resolved by this technical preparation; on the other hand, the use of a mixture of particulate support materials increases the complexity and the cost of the cosmetic product and in particular causes application difficulties in the case of packaging in the form of an aerosol spray.
    In addition to high cleaning power, many users of dry shampoos want to benefit from their use of additional styling and coloring effects, for example increased volume, improved hair texture and temporary hair colorings, so that they can dispense with products styling and additional temporary hair coloring products. Such styling effects can be obtained by the use of film-forming agents; the use of pigments for hair coloring is known per se. However, the use of these film-forming agents can cause the aerosol sprays to become blocked, because, due to the proportion of water induced by the film-forming agent, the support material in the form of particles can clump together. Often, the pigments used do not adhere sufficiently to the fibers and are notably eliminated under the effect of external environmental phenomena, such as rain, sweat and abrasion.
    The object of the present application was therefore to provide a dry shampoo having a high cleaning power and having good application properties as an aerosol spray application, the use of which makes it possible to obtain a large volume and / or an improved hair texture, and these effects are further characterized by a long-lasting action. In addition, after application, no visible residue or gray haze should remain on the hair. On the contrary, one must obtain a temporary water-resistant hair dye.
    Surprisingly, it has been found that these objectives can be achieved by the combination of pigment-containing starch as a support material and a special anionic polymer. This polymer is easily soluble in anhydrous solvents, but does not need to be neutralized for high halogenous properties. Consequently, the use of this polymer does not cause undesirable introduction of water, this causing agglutination of the support material and therefore a blockage of the aerosol nozzle. In addition, this anionic polymer does not have a negative influence on the cleaning effect of the starch containing pigments, so that in addition to the high styling effect, it is possible to obtain an exceptional cleaning power. . In addition, this combination does not cause the appearance of visible residues or persistent gray haze on the hair after the application of the composition according to the invention. On the contrary, by using a starch containing pigments, it is possible to obtain a temporary coloring of the hair. Thanks to the high resistance to water of the anionic polymer, the styling effects obtained, in particular the large volume and / or the improved capillary texture, as well as the temporary coloring, are therefore ensured over a long period, including in the event of high air humidity or water, sweat or abrasion, and can only be removed with the use of cleaning agents containing surfactants.
    A first object of the present invention is therefore a cosmetic composition containing - relative to its total weight a) at least one particle comprising - relative to its total weight a1) 65 to 98% by weight of at least one starch and a2) 1 , 0 to 3.0% by weight of at least one pigment,

    R 3 represents a C1-C12 alkyl group, branched or unbranched, saturated or unsaturated,
    R s represents a Cg-Cu alkyl group, branched or unbranched, saturated or unsaturated, and
    A represents oxygen, sulfur or an NH group and
    c) at least one propellant.
    According to your formulas above and all of the following formulas, a chemical bond marked with the symbol "*" represents a free valence of the corresponding structural fragment.

    By "particles" is meant particulate solids at 25 ° C and 1013 mbar. By pigments is meant within the meaning of the present invention coloring compounds having a solubility of less than 0.1 g / l at 20 ° C in water. Solubility in water can be achieved, for example, by the method described below: 0.1 g of the pigment is weighed in a beaker. A stirring bar is added. The beaker is then filled with 1 liter of distilled water (20 ° C). The mixture is stirred for one hour. If undissolved components of the pigment are still visible in the mixture after this time, the solubility of the pigment is less than 0.1 g / l.
    By “anionic polymer” is meant in the context of the present invention polymers which carry, in a practical solvent under standard conditions, at least one structural unit comprising permanent anionic groups, the anionic groups having to be compensated by counterions in order to to preserve electroneutrality. According to the invention, your anionic groups are in particular carboxyl groups.
    The data expressed in% by weight refer herein, unless otherwise stated, to the total weight of the cosmetic composition according to the invention, the sum of all the ingredients of the composition according to the invention giving 100% by weight.
    The cosmetic agent according to the invention contains, as the first essential component a), at least one particle comprising at least one starch a1) and at least one pigment a2).
    Starch is a reserve carbohydrate which is stored by many plants in the form of starch grains (granules), generally measuring from 1 to 200 µm, in various parts of plants, for example in your tubers or roots, seeds, your fruit and in the pulp. Starch belongs to the homoglycan family and is a polycondensation product of D-glucose. The preferred starches according to the invention are chosen from at least one polycondensation product of D-glucose obtained from native and / or physically modified starch from potatoes, corn, rice, peas, acorns, chestnuts, barley, wheat, bananas, sago, millet, sorghum, oats, rye, beans, sweet potatoes, maranta or cassava and their mixtures. In terms of cleaning power, the use of native and / or physically modified rice starch has been found to be particularly advantageous. By native starch is meant starch which is isolated from plants containing starch and which has not been physically or chemically modified after isolation and purification. By contrast, the term “physically modified starch” means a starch which has been subjected to at least one physical modification after isolation. By physical modification is meant herein a modification obtained by exploiting pressure and / or heat and / or light. However, a modification obtained by chemical and enzymatic reactions, for example the hydrolysis of starch, does not, according to the present, fall under the definition of physical modification. The use of heat, particularly the cooking of native starch, is a preferred physical modification. The preferred embodiments of the present invention are therefore characterized in that the particle a) contains at least one starch a1) chosen from chemically and / or physically modified rice starches, in particular from physically modified rice starch. with the use of native and / or physically modified rice starches, a particularly high adhesion of the pigments to the starch is obtained, so that in addition to the excellent cleaning power, this also allows hair coloring temporary with high resistance.
    According to the invention, it has been found that the composition of the starch particle itself has been found to be relevant for the cosmetic effect. Consequently, the particles a) used in a preferred manner are characterized by a certain proportion of native and / or physically modified starch, in particular rice starch. It is therefore preferred according to the invention that the at least one particle a) contains the at least one starch a1), in particular physically modified rice starch, in a total amount ranging from 70 to 96% by weight, in particular from 80 to 94% by weight, respectively based on the total weight of the particle. The use of particles containing a high proportion by weight of physically modified rice starch gives a particularly high cleaning power to cosmetic agents, without however prejudicing the long-lasting styling effects obtained by the anionic polymer, in particular the large volume. and / or improved hair texture, as well as temporary hair coloring.
    The particles a) contained in the cosmetic compositions also contain at least one pigment a2) in addition to the starch a1) mentioned above. In principle, all types of water-insoluble pigments are suitable, for example natural inorganic pigments (also called mineral pigments). These pigments mainly contain sulfides and oxides. Examples of such pigments include: ocher (Fe (OOH); Pigment Yellow 43), burnt Sienna (Fe 2 O 3 ; Pigment Red 102), Umbra (Fe 3 O 3 x MnO 2 ; Pigment Brown 7: x), vermilion (β-HgS, PR 106), lapis lazuli (Outremer, NaeAI 6 SÎ6O24 x Na 2 Sn; Pigment Blue 29), azurite (basic copper carbonate, Cu 3 [OH / CO 3 ] 2 ; PB 30), green earth (silicate containing FeO; Pigment Green 23), malachite (Cu 2 [(OH) 2 , CO 3 ]) and carbon black (carbon (graphite), Pigment Black 9). However, the use of synthetic inorganic pigments has proven to be advantageous in order to avoid the appearance of undesirable visible residues or gray haze or as a temporary water-resistant coloring of the fibers. Synthetic inorganic pigments are produced, for example, by chemical and / or physical conversion (melting, precipitation, annealing). These include in particular

    Pearlescent pigments, which consist of several layers with different refractive indices, are other preferred synthetic inorganic pigments. As free from pearlescent pigments of this type, mention may be made of magnesium stearate, zinc stearate and lithium stearate or ethylene glycol distearate or poly (ethylene terephthalate) as well as pearlescent pigments, essentially consisting of mica, titanium dioxide (titanium dioxide mica), bismuth chloride or guanine and which can also be covered with layers of colored oxides (for example iron or chromium oxides). Pearlescent pigments based on mica and based on mica / metal oxide are, as such, pearlescent pigments which are particularly preferred according to the invention. Mica is one of the phyllosilicates. The most important representatives of these silicates are muscovite, phlogopite, paragonite, biotite, lepidolite and margarite. In order to prepare your pearlescent pigments together with metallic oxides, mica, mainly muscovite or phlogopite, is covered with a metallic oxide. Suitable metal oxides include in particular TiO 2 , Cr 2 O3 and Fe 2 O 3 . By an appropriate coating, interference pigments and colored pearlescent pigments are obtained in the form of preferred pearly pigments according to the invention. In addition to a scintillating optical effect, these types of pearlescent pigments also have colored effects. In addition, your pearlescent pigments which can be used according to the invention may also contain a color pigment which does not derive from a metal oxide.

By "basic compounds" is meant according to the invention all the compounds which are capable of forming hydroxide ions in water or of playing the role of proton acceptors. These include in particular hydroxides of alkali and alkaline earth metals, carbonates of alkali and alkaline earth metals, ammonia as well as organic amines. Because during the neutralization of this polymer by basic compounds, water is released or entrained, which causes agglutination of the particles a) and thus a blockage of the aerosol nozzle. Therefore, it becomes impossible to completely empty the container. According to the invention, the expression “no / no basic compound (s)” means that these are present at a level of 0% by weight relative to the total weight of the composition. Particularly preferred embodiments of the first subject of the invention are therefore characterized in that the composition does not contain basic compounds, in particular no organic amine and / or hydroxides.
    Clogging of the aerosol nozzle can also be avoided if the compositions according to the invention contain only a small amount of water and if an anhydrous organic solvent is used as solvent for the anionic polymer. This avoids agglutination of the particles a), a phenomenon which closes the nozzle and prevents the aerosol container from being completely emptied. The particularly preferred compositions therefore contain water in a total amount ranging from 0 to 2.0% by weight, preferably from 0 to
    1.5% by weight, preferably from 0 to 1.0% by weight, in particular from 0 to 0.99% by weight, respectively based on the total weight of the composition. Consequently, the propellant c) as well as the anhydrous solvent of the anionic polymer b) serve as a support for the ingredients of the composition according to the invention.
    The anionic polymer b) is preferably dissolved in organic solvents to ensure, during the application of the composition, a uniform distribution over your hair and thus obtain long-lasting and water-resistant styling properties. In order to reduce the water supply and therefore the risk of agglutination of the particles a), an organic solvent is preferably used. It is therefore preferred according to the invention that the composition also contains ethanol in a total amount ranging from 3.0 to 8.0% by weight, in particular from 4.0 to 6.0% by weight, based the total weight of the composition. On the one hand, the amount mentioned above is sufficient to dissolve the anionic polymer b) and ensure uniform distribution over the hair. On the other hand, this amount does not cause excessive moistening of the hair, so that it is possible to carry out dry cleaning of the hair.

    Embodiments MR 1 to MR 76 contain water in a total amount ranging from 0 to 0.99% by weight, relative to the total weight of the composition, as well as preferably 0% by weight, based on the weight total of the respective embodiment, in basic compounds, in particular in organic amines and / or hydroxides. Thanks to the use of special particles a) in combination with special anionic polymers b), these embodiments have a significant cleaning power and cause, after maintenance, styling effects of long duration and water resistant, in in particular an increased capillary volume and / or an improved capillary texture, and temporary coloring effects. Thus, by using these dry shampoos, it is possible to dispense with the application phase of other styling agents and temporary coloring agents after the maintenance of the hair. Since the anionic polymer b) does not need to be neutralized and is soluble in organic solvents, the amount of water in these embodiments can be reduced, thereby avoiding the agglutination of the particles a). Consequently, these embodiments can be completely emptied of the aerosol containers, since the obstruction of the nozzles by the agglutination of the particles a) is avoided. In addition, this improves the applicability and cleaning power, since a uniform application of the particles a) to the hair is ensured.
    In addition to the components described above, the cosmetic compositions according to the invention may contain other ingredients, in particular additional nutrients.
    The composition may for example contain, as a nutrient, at least one protein hydrolyzate and / or one of its derivatives. Protein hydrolysates are mixtures of products which are obtained by degradation by acid, alkaline or enzymatic catalysis of proteins. By the term "protein hydrolysates" is meant according to the invention also total hydrolysates and individual amino acids and their derivatives and mixtures of different amino acids. The molecular weight of the protein hydrolysates that can be used according to the invention is between 75 Dalton, the molecular weight of glycine, and 200,000 Dalton; preferably, the molecular weight is from 75 to 50,000 Dalton and very particularly preferably from 75 to 20,000 Dalton.
    In addition, at least one vitamin, a provitamin, a vitamin precursor and / or one of the derivatives may be present as a nutrient. As such, the vitamins, provitamins and vitamin precursors are preferred according to the invention. , which usually belong to groups A, B, C, E, F and H.
    Examples of other suitable nutrients that may be mentioned include, for example, panthenol, caffeine, nicotinamide and sorbitol, and mixtures thereof.
    The compositions according to the invention may also contain, as a nutrient, at least one plant extract, but also mono- or oligosaccharides and / or lipids.
    The cosmetic compositions according to the invention are preferably used as dry shampoos for the maintenance of hair while obtaining lasting styling effects and temporary hair dyes.
    A second object of the present invention is therefore the use of a cosmetic composition according to the invention for the maintenance and the temporary temporary coloring of keratin fibers, in particular human hair.
    In principle, the term "keratin fibers" means all animal hair, for example wool, horsehair, angora hair, furs, feathers and your products or textiles derived therefrom. Preferably, however, the keratin fibers are human hair.
    The term “temporary dyes” means hair dyes which can be obtained using pigments or direct-acting dyes and which can be completely removed from the hair by repeated washing of the latter. However, hair colorings which use dye precursors by oxidation associated with oxidizing agents are excluded from the definition herein.
    As regards other preferred embodiments of the method according to the invention, in particular as regards the cosmetic composition used here, what has been explained on the compositions according to the invention applies mutatis mutandis.
    A third object of the present invention is a process for the maintenance and simultaneous temporary coloring of keratin fibers, in particular human hair, in which the cosmetic composition according to the invention is applied to keratin fibers.
    The cosmetic composition is applied to your keratin fibers in order to ensure their maintenance and their temporary temporary coloring. In an additional step, the composition can then be at least partially removed from the keratin fiber. This can for example be achieved by mechanical action on the fibers, in particular by painting or brushing them. Alternatively, the cosmetic composition can also be expelled from the hair, for example by means of a hair dryer.
    If the cosmetic composition is at least partially removed from the keratin fiber after application, the action time of the composition on your fibers is preferably between 1 and 10 minutes.
    A preferred embodiment of this object of the invention is therefore a process in which the cosmetic composition is left on the hair after application or is removed from the hair, at least partially, in particular completely, after application.
    An essential advantage of the method according to the invention is to clean the hair while carrying out a lasting and water-resistant styling and obtaining temporary coloring effects. This is obtained by the combination of the particles a) and the anionic polymer b) described above in relation to the first object.
    As regards other preferred embodiments of the process according to the invention, in particular as regards the cosmetic composition used here, what has been explained on your compositions according to the invention and on the use according to invention applies mutatis mutandis.

    1) physically modified rice starch 2) synthetic inorganic pigment from the group of iron oxides or pigment designed under the brand Colorona®, 3) polydimethylsiloxane, 4) containing structural units of formulas (I) to (III) in which R 1 ; R 4 respectively = H, R 2 ~ methyl group, R 3 = group * -CH 2 -C (CH 3 ) 2 , R 5 = group * C (CH 3 ) 2 -CH 2 -C (CH 3 ) 3 , A = NH
    The composition was prepared by mixing the raw materials 1 to 4, filling them in an aerosol can and pressurizing this can with the appropriate amount of propellant (raw material 5). The composition has good applicability and excellent cleaning power after application to the hair and brushing. In addition, after cleaning, we could notice an increased volume, an improved texture of the hair as well as a significant temporary hair coloring. The styling and coloring effect was water resistant and could only be removed after using cleaning agents containing surfactants. Even after prolonged storage, no blockage of the aerosol nozzle could be observed and the container could be completely emptied of the composition which it contained.
