Description

SOLID AQUEOUS GEL THAT COMPRISES A HYDROPHILIC GELIFICANT AND SPECIFIC CHARGES, COMPOSITIONS THAT CONTAIN IT, AND ITS USE Field of the Invention The present invention relates to a solid aqueous gel, to a solid composition in an aqueous continuous phase comprising said gel and to its use in the cosmetic field, particularly for the makeup of the skin and / or mucous membranes and / or of the keratin fibers. Products that are presented in solid form are known in the cosmetic industry. As products of this type, mention may be made, for example, in the field of make-up, sticks or "sticks" of red lips, make-up or eye shadow; in the field of skin or lip care, lip repair pencils, sticks or depigmentation sticks, make-up removers or moisturizers; in the field of hygiene, deodorant bars, bars or foaming tablets for shaving or for washing skin. Ref: 127342 In fact, it is particularly interesting to have products in the form of bars to the extent that such products are very practical to use, are easily transportable, the product does not run the risk of spilling. On the other hand, the makeup products are formulated quite generally on the basis, on the one hand, of a fatty phase for reasons of comfort and softness and on the other hand, of a powdery phase that provides the desired color. This pulverulent phase may comprise pigments and / or fillers and / or pearlescents. The fatty phase generally comprises waxes and / or oils and / or pasty compounds. Now, the bars formulated with waxes present certain drawbacks: they have a fatty character that is not appreciated by the users and they lack freshness in the application. Furthermore, it is difficult to introduce hydrophilic active agents therein. It is therefore increasingly sought to make makeup bars comprising an aqueous phase in the highest possible concentration. Of course it is well known to make non-greasy bars such as deodorant bars, but the latter rarely contain pigments or pearlescents. However, it has been proven that the presence of pigments or pearlescent in the bars of the aqueous produces problems of product desleido, ie intake of the product: in fact, these pigments and / or these pearlescent, indispensable in the products of makeup to provide the color, are solid particles not solubilized in the final composition. For this reason they are likely to interfere with the stability of the latter. On the other hand, it is essential, for a particular makeup product, that the extraction of the product be carried out ideally, that is to say, allow, in a simple way, with the help of the finger or a sponge or even directly on the skin of the patient. body for example, take not only the right amount of product (not too much so as not to lose product unnecessarily but enough to ensure a make-up effect) but also maintain the integrity of the product at the moment of its extraction: it is not necessary to break the product by a shearing phenomenon but to extract the whole of the product with the pigments and / or pearlescent, and / or possibly the fillers, which ensure the function of the make-up. Only with this condition is when the application of the product can be made homogeneously and when the makeup obtained will be uniform. Stable solid aqueous gels comprising pigments are known: but these products are generally impossible to dissolve; they break often, it is therefore impossible to pick up product with a finger or a sponge. Such products do not allow the deposit of a homogeneous film on the skin. There are also products that can be rejected, but are then too soft and end up breaking in repeated applications or even have syneresis phenomena with the passage of time, that is, the liquid part ends up exuding and the product has two phases: an unbreakable solid phase and a liquid phase. The product can no longer assure its function, namely make-up, since it is impossible to take pigments with a finger or with a sponge. In addition, aqueous rigid gels are described in WO-A-97/17055. However, these gels require the use of a fairly high concentration of gelling agent or resort to a particular preparation technique, extrusion. In addition, these bars, due to the high concentration of gelling agent, lack freshness and softness in the application on the skin.

SUMMARY OF THE INVENTION In order to remedy these problems of slippage, it has been proposed to incorporate in these gels charges of a particular chemical nature, such as silica or nylon. However, the products thus obtained have clearly insufficient cosmetic qualities: they are rough to the touch, they provide sensations of discomfort such as drying or tightness once the product has been deposited on the skin. They also present difficult application qualities in the presence of pigments.

There also remains a need for a solid aqueous gel, which does not have the drawbacks of the prior art. The applicant has unexpectedly discovered that by associating a charge of a particular nature, namely a charge of deformable particles, with a hydrophilic gelling agent, it was possible to make solid aqueous gels which optionally comprise pigments and / or pearlescents, these gels being able to easily dissolve with the finger or with the sponge or even directly on the skin of the face or body and presenting remarkable cosmetic qualities. The present invention thus relates to a solid aqueous gel comprising i) at least one hydrophilic gelling agent and ii) a powdery phase comprising at least one load of deformable particles, the hydrophilic gelling agent being present in the gel at a content less than or equal to 20% by weight, based on the total weight of the gel. The gels of the invention have excellent application and dissolving qualities. In particular, thanks to the association according to the invention, a level of disintegration higher than that of the known bars is obtained with equivalent hardness. The taking of the product is easy, it can be done directly on the body or with the finger or even with the sponge, extracting a sufficient amount of product, easy to apply on the skin in a homogenous way, without needing previous wetting. The gel spreads easily on the skin. The obtained makeup is uniform and homogeneous. These gels have excellent cosmetic qualities: the comfort and softness of the film after drying on the skin are improved. This film does not dry and does not provide a feeling of suspenders once dry. These gels are stable over time and with temperature. Thus, after having been kept for two months at room temperature or at 45 ° C, they do not present any phenomenon of syneresis (exudation) or even of lag: their appearance and their hardness have not changed. The gels according to the invention do not exude, even with low gelling percentages, and do not necessarily require the intervention of a particular preparation technician. They provide in the application a feeling of great freshness maintaining good cosmetic properties, in particular of softness. The subject of the present invention is also an aqueous continuous phase solid composition comprising a gel as defined above. The subject of the present invention is also a skin or keratin fiber makeup product comprising a gel and / or a composition as defined above. The subject of the present invention is also a method for making up the skin and / or the mucous membranes and / or the keratin fibers, consisting in applying to the latter, an aqueous gel and / or a solid composition and / or a product. of makeup such as have been defined above. In the sense of the present invention, gel or solid composition is understood as a gel or composition having a hardness defined by a maximum force before rupture ranging between 5 and 50 grams, at room temperature (20-25 ° C) ), after penetration by a 2 mm diameter stainless steel mobile into the gel matrix or composition with a thickness of 1 mm at a speed of 1 mm / sec and removal of said mobile from the gel matrix or composition at a speed of 2 mm / sec, the maximum force being measured before rupture with a texture analyzer of the "TAXT2" type marketed by the RHEO Company. Preferably still, the maximum force before rupture ranges between 7 and 40 g. The gel according to the invention comprises a hydrophilic geleficant. By "gelling agent" is meant a compound which creates, in the presence of a solvent, more or less strong intermacromolecular bonds which thus induce a three-dimensional network which fixes the said solvent. This hydrophilic geleficante can be chosen between polysaccharides, protein derivatives, synthetic or semi-synthetic gels of polyester type, polyacrylates or polymethacrylates and their derivatives. Among the polysaccharides, there may be mentioned: - algae extracts such as agar-agar, carrageenans (iota, kappa, lambda), alginates, in particular Na or Ca; -exudates of micro-organisms such as xanthan gum and its derivatives as the product sold under the trade name "Rhéosan" by the company Rhodia Chimie, gelano, -the fruit extracts such as pectins; - gelling agents of animal origin such as protein derivatives, in particular gelatin, ox or fish, caseinates; -polysaccharides having a side chain and 6 neutral sugars as described in FR-A-2759377. -and its mixtures. Preferably, the hydrophilic gelling agent is chosen from polysaccharides, and preferably also, the hydrophilic gelling agent is gellan.

As products which are particularly suitable for the invention, mention may be made of gellan gum sold under the trade name "Kelcogel F" by the company NUTRASWEET-KELCO or even the carrageenan iota sold under the trade names "Seaspen PF 357" or "Viscarin". SD 389"by the FMC Company. The hydrophilic gelling agent is present in the gel according to the invention at a concentration of up to 20% by weight and preferably between 0.2 and 10% by weight, based on the total weight of the gel. This concentration allows to obtain the suitable hardness and consistency for an ideal desleido. The gel according to the invention also comprises a powdery phase comprising at least one charge of deformable particles. By fillers, it is necessary to comprise colorless or white, mineral or synthetic, spherical or non-spherical particles, intended to give body or rigidity to the composition, and / or softness, matte color and uniformity to make-up. By load of deformable particles,. it is understood, in the sense of the present invention, spherical particles or not of hardness sufficiently low to deform in the extraction of the composition with the finger or with the sponge or directly by friction on the skin when it is a bar. In particular, by "deformable" it is necessary to understand that the particles are flexible and elastic: after crushing, they recover their initial shape. These particles can be of any chemical nature. Preferably, they have an average particle size ranging from 0.1 to 500 microns, and preferably from 1 to 100 microns. They can be full or hollow. As examples of filled deformable particles, mention may be made of crosslinked organosiloxane particles or "silicone rubber powder" as described in JP 10 175816 whose JIS A hardness is equal to or less than 80 and preferably less than 65. These particles can be coated with surfactant or with an organic fine powder. They may also contain a non-crosslinked silicone or hydrocarbon oil which can exude from the "silicone rubber powder". Mention may be made of 63% silicone rubber powders in aqueous dispersion sold under the trade names "BY-29-119", "BY-29-122" by Dow Corning. The filled deformable particles that can be used according to the present invention preferably have a density ranging between 0.8 and 4, preferably still between 0.8 and 1.5. When the deformable particles are hollow or even filled by a gas or air, they advantageously have a density ranging between 0.015 and 0.2 and better than 0.04 and / or less than 0.1 and particularly between 0.06 and 0.08. It is possible, for example, to use a copolymer containing: from 1% to 60% by weight, relative to the total weight of the copolymer, of units derived from vinylidene chloride, from 20% to 90% by weight, with respect to the total weight of the copolymer of units derived from acrylonitrile and from 1% to 50% by weight, based on the total weight of the copolymer of units derived from an acrylic monomer, the sum of the percentages by weight being equal to 100 The acrylic monomer is, for example, a methyl acrylate or methacrylate and, in particular, methacrylate. These particles occur mainly in the dry or hydrated state. This copolymer is not toxic or irritating to the skin. Preferably, the hollow particles are in the form of microspheres and have a mean size or granulometry ranging from 10 μm to 60 μm. The hollow particles of the invention can be obtained, for example, according to the procedures of the patents and patent applications EP-56 219, EP-348-372, EP-486-080, EP-320,473, EP-112.807, and US.3,615,972. The internal cavity of the particles contains in principle a gas that can be air, nitrogen or a hydrocarbon such as isobutane or isopentane.

Preferably, the loads of deformable particles are present in the gels according to the invention with a content ranging from 0.1 to 50% by weight, based on the weight of the gel. This content may vary, in particular as a function of the density of the charge of deformable particles. Thus, when this filler has a density ranging from 0.015 to 0.2, then it is preferably present in a content ranging from 0.1 to 10% by weight, based on the total weight of the gel. When this charge has a density ranging between 0.8 and 4, then it is preferably present in a content ranging between 1 and 50% by weight, based on the total weight of the gel. For example, for the hollow deformable particles such as the aforementioned Expanceles, this content will generally be from 0.1 to 10% by weight, of particles and better than 0.3 to 5% by weight, and still from 0.3 to 5% by weight. 2% by weight, based on the total weight of the gel.
