Description

Title of the invention: Solid composition comprising a cationic surfactant, a starch, a polyol and a cationic polymer

[0001] The present invention relates to a solid composition intended in particular for the cosmetic treatment, and more particularly for the care, of keratin fibers, in particular human keratin fibers such as hair, and which comprises at least one cationic surfactant, at least one starch, at least one polyol and at least one cationic polymer.

[0002] The invention also relates to a packaging article containing said solid composition, as well as cosmetic treatment methods for keratin fibers, in particular human keratin fibers such as hair, implementing said solid composition or said packaging article.

[0003] The invention further relates to the use of said solid composition or said packaging article for the cosmetic treatment, preferably the care, of keratin fibers, in particular human keratin fibers such as hair.

[0004] In the field of hair hygiene, keratin fiber care (or conditioning) products are generally intended to condition these fibers to provide them with good cosmetic properties. Conventional products, such as conditioners, are most often in liquid form, more or less thickened. However, due to their liquid texture, these products can present several drawbacks, notably being difficult to measure.

[0005] Indeed, the more liquid they are, the more they tend to slip through the fingers, making them difficult to measure and leading to waste. These products can also leak from their packaging, which can cause inconvenience to the consumer when these products come into contact with clothing or objects, for example, during travel.

[0006] In order to modify the texture of these products, and in particular to make them more compact, thickeners are generally used. However, the addition of these compounds often comes at the expense of the cosmetic effects of the compositions. Furthermore, the use of these thicker compositions requires a large amount of rinsing water to remove the excess product from the fibers. Yet, in many countries where access to water is limited, rinsing time, and consequently the amount of water needed to thoroughly rinse the product, are key indicators of a composition's performance.

[0007] To overcome some of these problems, new solid cosmetic formulations, particularly conditioners in the form of solid granules or powder, have been developed. Such formulations are described, for example, in US 2021 / 007960. However, these new formulations do not always provide complete satisfaction. Those in loose powder form can present problems with volatility, grip, and / or dosage. Those in agglomerate form, such as granules, can tend to disintegrate or crumble with difficulty in the presence of water, adversely impacting their use and application to keratin fibers, and do not always provide satisfactory care. They can also be difficult to rinse out and sometimes even leave residues on the fibers that are unpleasant for the consumer.

[0008] Conditioners in powder or particle form may lose fluidity during storage due to the agglutination of the solid unit particles together, which may negatively impact the qualities of use.

[0009] These formulations may also not give complete satisfaction in terms of cosmetic performance, in particular in terms of suppleness, feel, softness, detangling, smoothing, and shine.

[0010] Thus, there is a real need to provide a solid composition with an improved environmental profile, i.e., one requiring little water throughout its use. The composition must not only be easy to grasp and break down easily, but it must also rinse quickly without leaving residues on the keratin fibers. With regard to solid compositions in powder or particle form in particular, these must not clump together during storage in order to avoid deteriorating their performance qualities.

[0011] The composition must also provide good cosmetic properties, particularly in terms of suppleness, feel, softness, coating, shine and detangling.

[0012] It has now been discovered that a solid composition comprising at least one cationic surfactant, at least one starch, at least one polyol and at least one cationic polymer makes it possible to achieve the objectives set out above, and in particular to offer a composition in solid form combining good conditioning power, without requiring large quantities of water.

[0013] The present invention therefore relates to a solid composition comprising: i) one or more cationic surfactants, ii) one or more starches, iii) one or more polyols, and iv) one or more cationic polymers.

[0014] Said solid composition may more particularly be a cosmetic composition, in particular a hair composition, and advantageously, a hair conditioning composition.

[0015] The specific combination of compounds in the invention makes it possible to obtain a solid composition that is easy to scoop, handle, and dose. Indeed, the resulting composition exhibits a cohesion or granulation such that its gripping and dosing properties are improved, while avoiding unwanted agglomerations that could negatively impact its performance. The composition can then be packaged in single-dose form, a format that is particularly advantageous, for example, when traveling or playing sports (lighter bags, reduced risk of leaks, less waste).

[0016] In addition, this composition breaks down rapidly on contact with water and allows for easy and rapid spreading and homogeneous distribution on keratin fibers comparable to those of a classic liquid conditioner composition.

[0017] The composition according to the invention also makes it possible to obtain a good coating of the keratin fibers, with a homogeneous and slippery finish.

[0018] Furthermore, the composition of the invention rinses quickly without leaving unpleasant residues on the fibers and gives them a natural and clean feel after rinsing. Fibers treated with the composition of the invention exhibit good cosmetic properties, particularly in terms of softness, suppleness, and feel. They are also well-defined and thus easier to detangle.

[0019] The present invention also relates to a cosmetic treatment method, in particular a care method, for keratin fibers, in particular human keratin fibers such as hair, comprising the application to said keratin fibers of a solid composition as defined below, the solid composition being applied directly to said keratin fibers or after having been previously moistened with water.

[0020] The present invention further relates to the use of a solid composition as defined below for cosmetic treatment, preferably the care of keratin fibers, in particular human keratin fibers such as hair.

[0021] The present invention also relates to a packaging article comprising: - an envelope defining at least one cavity, the envelope comprising one or more water-soluble and / or fat-soluble compounds; - a solid composition as defined above; it being understood that the solid composition is located in one of the cavities defined by the envelope.

[0022] This packaging device makes it possible, in particular, to solve the problems of dosing the solid composition. It also facilitates its storage and transport. In particular, the packaging device of the invention offers better protection of the composition against moisture.

[0023] The conditioning article may also allow a final keratin fiber care composition to be thicker in the hand, which may be in the form of a cream, without lumps, without leaving residues on the hair after rinsing.

[0024] The conditioning article can thus improve, in particular facilitate, the distribution of the composition on the keratin fibers.

[0025] The packaging article can allow better control of the dose of composition implemented on the keratin fibers, thus reducing the risks of waste.

[0026] The packaging article also helps to minimize the risks of disintegration of the composition.

[0027] The invention also relates to the use of the above conditioning article for cosmetic treatment, preferably for the care of keratin fibers, in particular human keratin fibers such as hair.

[0028] The invention also relates to a cosmetic treatment process, in particular a care process, for keratin fibers, in particular human keratin fibers such as hair, comprising a step of implementing at least one packaging article as defined above.

[0029] Preferably, said cosmetic treatment process comprises the following steps: a) mix the conditioning article in a composition suitable for solubilizing, in whole or in part, the casing of said conditioning article, b) apply the composition obtained in step a) to the keratin fibers, c) optionally leave to stand, d) rinse said keratin fibers, e) possibly dry said keratin fibers.

[0251] The lubricant(s) that can be used are different from the cationic polymers defined above.

[0288] Preferably, the water-soluble polymers are polymerized from one or more monomers selected from vinyl alcohol of formula CH2=CHOH, vinyl acetate of formula CH2=CHOC(O)CH3 and mixtures thereof.

[0289] The water-soluble polymers suitable for forming the outer shell of the packaging article may also be selected from water-soluble polymers derived from natural products, such as polysaccharides, i.e., polymers with sugar motifs. These water-soluble polymers are distinct from the cationic polysaccharide(s) that may be present in the solid composition.

[0290] By "sugar motif" is meant a motif derived from a carbohydrate of formula Cn(H2O)ni or (CH2O)n which may be modified by substitution and / or oxidation and / or dehydration. The sugar motifs which may be included in the composition of the polymers of the invention are preferably derived from the following sugars: glucose, galactose, arabinose, rhamnose, mannose, xylose, fucose, fructose, anhydrogalactose, galacturonic acid, glucuronic acid, mannuronic acid, galactose sulfate, anhydrogalactose sulfate.

[0293] These polymers can be modified physically or chemically. Physical treatments include temperature. Chemical treatments include esterification, etherification, amidation, and oxidation reactions. These treatments lead to polymers that can be nonionic, anionic, cationic, or amphoteric.

[0294] Preferably, these chemical or physical treatments are applied to guar gums, locust bean gums, starches and celluloses.

[0295] The non-ionic guar gums usable according to the invention can be modified by hydroxylakyl groups in C1 to C6. Among the hydroxyalkyl groups, mention may be made of the hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.

[0296] These guar gums are well known from the prior art and can, for example, be prepared by reacting corresponding alkene oxides such as, for example, propylene oxides with guar gum, so as to obtain a guar gum modified by hydroxypropyl groups.

[0297] The degree of hydroxyalkylation varies preferably 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.

[0298] Such non-ionic guar gums possibly modified by hydroxyalkyl groups are for example sold under the trade names JAGUAR HP8, JAGUAR HP60 and JAGUAR HP120 by the company RHODIA CHIMIE.

Preferably, 2 to 30% by number of the hydroxyl groups of these guar gums bear trialkylammonium cationic groups. Even more preferably, 5 to 20% of the hydroxyl groups of these guar gums are branched by trialkylammonium cationic groups. Among these trialkylammonium groups, trimethylammonium and triethylammonium groups are particularly noteworthy. Even more preferably, these groups represent 5 to 20% by weight relative to the total weight of the modified guar gum.

[0300] According to the invention, guar gums modified with 2,3-epoxypropyl trimethylammonium chloride can be used.

Preferably, the amphoteric starch is a starch chloroethylamido dipropionate.

[0305] Cellulose and cellulose derivatives can be anionic, cationic, amphoteric or non-ionic.

[0306] Among these derivatives, we distinguish cellulose ethers, cellulose esters and cellulose ether esters.

[0307] Among the cellulose esters, we can mention inorganic cellulose esters (cellulose nitrates, sulfates or phosphates), organic cellulose esters (cellulose monoacetates, triacetates, amidopropionates, acetatebutyrates, acetatepropionates or acetatetrimellitates) and mixed organic / inorganic cellulose esters such as cellulose acetatebutyratesulfates and acetatepropionatesulfates.

The quaternizing agent may be, in particular, diallyldimethylammonium chloride (for example, Celquat L200 from NATIONAL STARCH). Another cationic cellulose ether is hydroxyethylcellulose hydroxypropyltrimethylammonium (for example, Ucare polymer JR 400 from AMERCHOL).

[0314] The water-soluble polymer(s) with sugar motif(s) usable to form the envelope of the packaging article are preferably chosen from guar gums, locust bean gums, xanthan gums, starches and celluloses, in their modified (derivatives) or unmodified form.

[0315] Preferably, the sugar motif(s) polymer(s) are non-ionic.

[0316] The water-soluble polymers described above more particularly have a weight-average molecular weight (Mw) greater than 1,000,000 and preferably between 1,000,000 and 50,000,000. The molecular weight is determined by the RSV (Reduced Spec Viscosity) method as defined in "Principles of Polymer Chemistry" Cornell University Press, Ithaca, NY 1953 Chapter VII "Determination of molecular Weight" pp 266-316.

[0317] The water-soluble or fat-soluble compound(s) capable of forming the envelope of the packaging article according to the invention may be in the form of fibers or film.

[0318] According to a first embodiment, the water-soluble or fat-soluble compound(s) are in the form of fibers. The term "fiber" means any object whose length is greater than its cross-sectional area. In other words, it refers to an object of length L and diameter D such that L is greater than, and preferably much greater than (i.e., at least three times greater than), D, where D is the diameter of the circle in which the cross-section of the fiber is inscribed. In particular, the L / D ratio (or aspect ratio) is chosen from the range of 3.5 to 2500, preferably from 5 to 500, and better still from 5 to 150. The cross-section of a fiber can be any shape: round, serrated, grooved, or bean-shaped, but also multilobed, in particular trilobed or pentalobed, X-shaped, ribbon-shaped, square, triangular, elliptical, or otherwise. The fibers of the invention can be hollow or solid.

[0319] According to this embodiment, the fibers can be spun, carded, or twisted. Advantageously, the fibers used in the context of the present invention are spun. The average diameter of the fibers used according to the present invention, whether identical or different, is less than 500 µm. Advantageously, such a diameter is less than 200 µm, preferably less than 100 µm, or even less than 50 µm.

[0320] Water-soluble fibers, in particular, include poly(vinyl alcohol) (PVA)-based fibers, polysaccharide fibers such as glucomannans, starches, celluloses such as carboxymethylcelluloses, polyalginic acid fibers, polylactic acid fibers, and polyalkylene oxide fibers, as well as mixtures thereof. More preferably, the water-soluble fiber(s) used in the invention are chosen from among PVA-based fibers.

[0321] The fibers of the casing are generally intertwined. A "casing comprising water-soluble fibers" is understood to mean a casing that can be entirely composed of water-soluble fibers and that may include both water-soluble and water-insoluble fibers at a temperature of 35°C or lower, with the soluble fibers being more abundant than the insoluble fibers. The fiber casing must comprise at least 60% by weight of soluble fibers, preferably at least 70%, and better still at least 80% by weight relative to the total weight of the fibers. It may thus comprise, for example, more than 95% by weight, or even more than 99% by weight and even 100% by weight of water-soluble fibers relative to the total weight of the casing fibers.

[0322] When the envelope contains insoluble fibers, these can be of any material commonly used as insoluble fibers; for example, silk, cotton, wool, linen, polyamide (Nylon®), polylactic acid, modified cellulose (rayon, viscose, rayon acetate), poly-p-phenylene terephthalamide in particular Kevlar®, polyolefin and in particular polyethylene or polypropylene, glass, silica, aramid, carbon in particular in the form of graphite, Teflon®, insoluble collagen, polyesters, polyvinyl chloride or vinylidene, polyethylene terephthalate, fibers formed from a mixture of the compounds mentioned above, such as polyamide / polyester or viscose / polyester fibers.

[0323] Furthermore, when the casing contains fibers, it can be woven or non-woven.

[0324] According to a first embodiment of the invention, the casing can be woven. Within the scope of the present invention, a "woven" material results from an organized assembly of fibers, in particular water-soluble polymeric fibers, and more particularly from an interlacing, in the same plane, of said fibers, arranged in the warp direction, and fibers arranged, perpendicular to the warp fibers, in the weft direction. The bonding obtained between these warp and weft fibers is defined by a weave.

[0325] Such a woven material results from an operation aimed at assembling the fibers in an organized manner such as weaving properly speaking, but can also result from knitting.

[0326] According to another variant of the invention, the envelope is non-woven.

[0327] For the purposes of this invention, "non-woven" means a substrate comprising Nonwovens are fibers, particularly water-soluble polymeric fibers, in which the individual fibers are arranged randomly in a sheet-like structure and are neither woven nor knitted. The fibers of nonwovens are generally bonded together, either by mechanical means (e.g., needle punching, air jetting, water jetting), by thermal action, or by the addition of a binder.

[0328] Such a nonwoven is for example defined by ISO 9092 as a web or sheet of directionally or randomly oriented fibers, bonded by friction and / or cohesion and / or adhesion, excluding paper and products obtained by weaving, knitting, tufting or sewing incorporating binding yarns or filaments.

[0329] A nonwoven fabric differs from paper in the length of the fibers used. In paper, the fibers are shorter. However, there are nonwoven fabrics based on cellulosic fibers that are manufactured using a wet process and have short fibers, similar to those in paper. The difference between a nonwoven fabric and paper is generally the absence of hydrogen bonding between the fibers in a nonwoven fabric.

[0330] Most preferably, the fibers used in the context of the present invention are chosen from synthetic fibers such as PVA fibers. In particular, the sheath is non-woven, and preferably made of non-woven PVA fibers.

[0331] To produce the nonwoven cover of the packaging article, water-soluble PVA fibers are preferably used at a temperature of 35°C or lower, such as the fibers sold by the Japanese company Kuraray under the name KURALON K-II, and particularly the WN2 grade, which is soluble from 20°C. These fibers are described in document EP-A-636716, which teaches the manufacture of water-soluble PVA fibers at temperatures not exceeding 100°C, by spinning and drawing the polyvinyl alcohol polymer in a dry or wet state in the presence of solvents that solubilize and solidify the fiber. The fiber thus obtained can be used to produce woven or nonwoven substrates.

[0332] These fibers can also be prepared from a spinning solution by dissolving a water-soluble PVA-based polymer in a first organic solvent, spinning the solution in a second organic solvent to obtain solidified filaments, and then wet-drawing the filaments, removing the first solvent, drying them, and subjecting them to heat treatment. The cross-section of these fibers can be substantially circular. These fibers have a tensile strength of at least 2.7 g / dtex (3 g / d). EP-A-0 636 716 describes such water-soluble PVA-based fibers and their manufacturing process.For example, fibers can also be formed by extrusion and deposited on a conveyor to form a fiber web which is then consolidated by a conventional fiber bonding technique, such as needle punching, hot bonding, calendering or hot air bonding (air through bonding), a technique in which the water-soluble web passes through a tunnel where hot air is blown, or hydrobonding which aims to bond the fibers under the action of fine jets of water under very high pressure, which cannot be applied to fibers whose dissolution temperature is too low.

[0333] As we have seen previously, the invention is not limited to the use of PVA, and fibers made from other water-soluble materials can also be used provided that these materials dissolve in water having the desired temperature, for example polysaccharide fibers marketed under the name LYSORB by the company LYSAC TECHNOLOGIES, INC or other fibers based on polysaccharide polymers such as glucomannans or starch.

[0334] The envelope may comprise a mixture of different water-soluble fibers at different temperatures (up to 35°C).

[0335] The fibers can be composite, and they can include, for example, a core and a sheath not of the same nature, for example formed of different grades of PVA.

[0336] According to a particular embodiment of the invention, the cover is a non-woven fabric comprising water-soluble fibers, alone or mixed with insoluble fibers as described above, with a maximum of 40% by weight of insoluble fibers relative to the total weight of the fibers constituting the layer. Preferably, the non-woven fabric consists essentially of water-soluble fibers, that is to say, it does not contain insoluble fibers.

[0337] According to another embodiment of the invention, the packaging material may consist of one or more films, each comprising one or more water-soluble and / or fat-soluble compounds, in particular those defined above. When the packaging material consists of several films, said films may be joined, for example glued together, to form a single unit film.

[0338] The thickness of the "global" film (i.e. the thickness of the single film when the envelope contains only one or of the unit film when the envelope contains several films) is advantageously between 10 and 1000 microns, preferably between 10 and 800 microns, and more preferably between 15-500 microns.

[0339] Film means, in particular, a continuous layer preferably formed of one or more water-soluble and / or fat-soluble compounds as defined above, in particular of polymer(s).

[0340] The main industrial methods of producing polymeric films are the extrusion of a molten polymer, the pouring of a polymer solution onto a polished metal surface (in some cases, the polymer solution is introduced into a precipitation tank), the pouring of a polymer dispersion onto a polished surface and calendering.

[0341] The films usable according to the present invention can be chosen from multilayer film-film, film-paper (coating) and film-coating.

[0342] During application by spraying, brushing, or various industrial processes, surface coatings undergo what is known as film formation, and in particular, the formation of a coating film. In most film formation processes, a liquid coating of relatively low viscosity is applied to a solid substrate and is cured into a solid, adherent film based on a high molecular weight polymer possessing the properties desired by the user.

[0343] Films usable according to the present invention include PVA films that can be manufactured from any industrial production method, such as a method of casting a PVA-based polymeric solution, an extrusion method in the presence or absence of water, a dry extrusion molding method or a biaxial orientation method.

[0344] The packaging material, as well as the envelope, may have any shape suitable for the intended use, for example, a rectangular, round, or oval shape. Preferably, it has a rounded geometry, for example, in the form of a sphere, disc, or oval, or is square or parallelepiped, preferably with rounded corners. The envelope preferably has dimensions that allow it to be grasped between at least two fingers. Thus, it may, for example, have an ovoid shape approximately 2 to 10 cm long and approximately 0.5 to 4 cm wide, or a circular disc shape approximately 2 to 10 cm in diameter, or a square shape approximately 2 to 15 cm on each side, or a rectangular shape approximately 2 to 25 cm long, it being understood that it may have any other shape and dimensions suitable for the intended use.

[0345] Preferably, the envelope can be round in shape with an internal diameter of 3 to 7 cm, more preferably 4 to 5 cm; to which can be added the dimension of the edges (sealed part) which can range from 1 to 5 mm, better from 2 to 4 mm; and a height of 2 to 7 mm, preferably from 3 to 5 mm.

[0346] The envelope may also be square or rectangular in shape with a length preferably from 2 to 6 cm, more preferably from 3 to 5 cm, and a width preferably from 2 to 5 cm, more preferably from 2.5 to 4 cm; to which may be added the dimension of the edges (sealed part) which may preferably range from 1 to 5 mm, and more preferably from 2 to 4 mm.

[0347] Advantageously, the casing has a low thickness and can be made of several layers of different materials. Preferably, the thickness of the casing ranges from 3 to 99.9% of its other dimensions. The casing is thus substantially flat, with thin edges.

[0348] The surface area delimiting the cavity or cavities advantageously has an area less than 625 cm², preferably between 0.025 cm² and 400 cm², more preferably between 1 and 200 cm², better between 2 and 50 cm², and even better between 4 and 25 cm², in order to achieve optimized compaction of the composition. It has been observed that when the surface area of ​​the article is within the above ranges, the compaction of the solid composition into powder is less pronounced, and the transformation of the powder into a fluid composition in the hands is easier, without the formation of agglomerates.

[0349] Preferably, the height of the envelope is greater than or equal to 2 mm, more preferably from 2 to 10 mm, and even better from 3 to 7 mm.

[0350] Preferably, the film or films used in the context of the present invention are chosen from synthetic films, such as PVA and / or PVOH films, as well as mixtures thereof.

[0351] Preferably, the envelope consists of several layers, for example, 2 or 3 layers, of films each preferably made of different materials. Advantageously, at least one of these films is a film comprising or consisting of PVA and / or PVOH.

[0352] Preferably, the film or films are sealed to form one or more cavities which will include the solid composition of the invention and prevent it from escaping.

[0353] Advantageously, the envelope represents from 0.5 to 20% by weight, preferably from 1 to 15% by weight, more preferably from 2 to 10% by weight, better from 4 to 10% by weight, and better still from 4 to 8% by weight, relative to the total weight of the packaging article.

[0354] Advantageously, the solid composition as defined below represents 80 to 99.5% by weight, preferably 85 to 99% by weight, more preferably 90 to 98% by weight, better still 90 to 96% by weight, and better still 92 to 96% by weight, relative to the total weight of the packaging article.

[0355] The weight ratio between the total weight of the solid composition of the invention and the total weight of the envelope advantageously goes from 80 / 20 to 99 / 1, preferably from 85 / 15 to 98 / 2, and more preferably from 90 / 10 to 97 / 3.

[0356] Advantageously, the packaging article comprises 1 to 8g, preferably 2 to 6g of solid composition; and 0.1 to 1g, preferably 0.2 to 0.7g of envelope.

[0357] The present invention further relates to a cosmetic treatment process for keratin fibers, in particular human keratin fibers such as hair, comprising a step of implementing a packaging article as defined above; preferably, said cosmetic treatment process comprises the following steps: i) mix the conditioning article in a composition capable of solubilizing, in whole or in part, the casing of said conditioning article, ii) apply the composition obtained in step i) to the keratin fibers, iii) optionally leave to set, (iv) rinse the said keratin fibers, and v) possibly dry said keratin fibers.

[0358] It is understood that the composition suitable for solubilizing the coating depends on the nature of the coating. In other words, the composition suitable for solubilizing the coating is water or an aqueous composition when the packaging article contains predominantly or solely a hydrophilic coating. And, the composition suitable for solubilizing the coating is an anhydrous organic composition or an aqueous composition comprising at least one liquid fat or at least one organic solvent other than liquid fats, such as inferior monoalcohols, for example ethanol, or polyols, for example propylene glycol or glycerin. when the packaging item contains mostly or exclusively a lipophilic envelope.

[0359] Thus, the aqueous composition may simply be water. The aqueous composition may optionally include at least one polar solvent. Among the polar solvents that can be used in this composition are organic compounds that are liquid at room temperature (25 °C) and at least partially miscible with water.

[0360] By way of example, one can cite more particularly alcohols such as ethyl alcohol, isopropyl alcohol, aromatic alcohols such as benzyl alcohol, and phenylethyl alcohol, or polyols or polyol ethers such as, for example, monomethyl, monoethyl and monobutyl ethers of ethylene glycol, propylene glycol or its ethers such as, for example, monomethyl ether of propylene glycol, butylene glycol, dipropylene glycol as well as alkyl ethers of diethylene glycol such as, for example, monoethyl ether or monobutyl ether of diethylene glycol.

[0361] More particularly, if one or more solvents are present, their respective content in the aqueous composition varies from 0.5 to 20% by weight, and preferably from 2 to 10% by weight, relative to the weight of said aqueous composition.

[0362] The dilution ratio (expressed by weight) between one or more packaging articles, as defined above, and the composition suitable for solubilizing the packaging article(s) is preferably between 10 / 90 and 90 / 10, and more preferably between 10 / 90 and 50 / 50. Better still, this dilution ratio is 20 / 80.

[0363] In particular, the composition obtained after mixing (step i) of the process) can be applied to dry or wet keratin fibers. It is advantageously left to remain on the keratin fibers for a period of 1 to 15 minutes, preferably 2 to 10 minutes.

[0364] Then, the keratin fibers are rinsed with water. They may optionally be washed with shampoo, followed by rinsing with water, before being dried or left to dry.

[0365] The present invention further relates to the use of a conditioning article as defined above for the cosmetic treatment, more particularly the care, of keratin fibers, in particular human keratin fibers such as hair.

[0366] The following examples serve to illustrate the invention without, however, being limiting in nature.

[0367] Examples In the examples that follow, all quantities are given, unless otherwise indicated, as a mass percentage of active material (%AM) relative to the total weight of the composition.

[0368] Example 1 A composition 1 according to the invention was prepared from the ingredients indicated in Table 1 below, the contents of which are indicated as % by weight of MA relative to the total weight of the composition:

[0370] The powdered ingredients (corn starch, starch phosphate, citric acid, guar) were mixed with agitation in a tank. The liquid ingredients (except the fragrance) were heated to 40°C. These ingredients were added as a binder to the tank by spraying and mixed. Finally, the fragrance was added by spraying and mixed. The mixture was then dried in an oven at 45°C for 20 hours. After cooling to room temperature, the mixture was ground using a grinder to obtain a powder. A fairly free-form powder formulation (with a slope angle of 30°) was obtained. a density of 0.48 and water activity 0.628 (after drying). Particle size before grinding X50%=286 µm and after grinding X50%=216 µm.

[0371] According to the present invention, the slope angle represents the characteristic angle of a powder pile obtained by mechanically pouring the powder from a funnel and constitutes an indication of the flowability of a powder. As an example, a clogging powder with difficult flow has a slope angle greater than 55°.

[0372] The composition thus prepared is packaged in powder form in a water-soluble sachet made from PVA. The packaging thus obtained can then be used as a care composition: it is placed in the palm of the hand, water is added to dissolve it and form a cream, and then applied to the hair, preferably previously moistened.

[0375] The powdered ingredients (corn starch, distarch phosphate, citric acid, guar gum, sodium chloride, magnesium carbonate) were mixed with agitation in a tank. The liquid ingredients (except the fragrance) were heated to 40°C. These ingredients were added as a binder to the tank by spraying and mixed. Finally, the fragrance was added by spraying and mixed. The mixture was then dried in an oven at 45°C for 20 hours. After cooling to room temperature, the mixture was ground using a grinder to obtain a powder.

[0376] A powder was obtained for composition A according to the invention while the comparative composition B formed a paste.
