Description

SOLID AQUEOUS GEL THAT COMPRISES A HYDROPHILIC AND STARCH GELIFICANT, COMPOSITION THAT UNDERSTAND IT, AND ITS USE Field of the Invention The present invention relates to a solid aqueous gel, to an aqueous continuous phase solid composition 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 gueratinic fibers. Products that are presented in solid form are known in the cosmetic industry. As products of this type, there may be mentioned, for example, in the field of painting, the sticks or "sticks" of red lips, of background makeup or of 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: 127344 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, makeup products are generally formulated 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. There are products that fade well but are often too soft and end up breaking in repeated applications or even have phenomena of syneresis over time, ie the liquid part ends up exuding and the product has two phases: a solid phase indesleible 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. On the other hand, there are aqueous gels that include pigments: but a phenomenon of sedimentation is often observed during manufacturing, particularly during the cooling phase. 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 hydrophilic gelling agent with a compound of a particular nature, namely a starch or its derivatives, 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) at least one starch or its derivatives. 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. No phenomenon of sedimentation of the pigments is observed in the course of manufacture, particularly in the cooling phase. In addition, after having been maintained two months at room temperature or at 45 ° C, these gels do not present any phenomenon of syneresis (exudation) or even of phase shift: 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 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.

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, comprising applying to the latter, a solid aqueous gel and / or 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 such as described in FR-A-2759377. -and its mixtures. Among the synthetic or semi-synthetic gels, mention may be made of the copolyesters described in application FR-A-2,760,643. 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. The gel according to the invention also comprises a starch or one of its derivatives. The starches and their derivatives usable in the present invention are more particularly macromolecules in the form of polymers constituted by elementary units which are anhydroglucose units. The number of these units and their assembly allow distinguishing amylosis (linear polymer) and amylopectin (branched polymer). The relative proportions of amylose and amylopectin, as well as their degree of polymerization, vary depending on the botanical origin of the starches. The starches used in the present invention can have as a botanical origin the cereals or even the tubers. Thus, starches are, for example, chosen from maize, rice, cassava, potato, wheat, sorghum, pea, natural (ie unmodified) or modified starches. Among the modified starches, mention may be made of pre-cooked starches, hydrolyzed starches, cross-linked starches, for example by a methylol urea derivative or by octenyl succinic anhydride or even by epichlorohydrin, esterified starches, etherified starches, oxidized starches , refined starches, starches calcined in the presence of acid, or even grafted starches, for example by means of sodium polyacrylates, coated starches, for example by means of amino acids, and / or their mixtures. The starches are generally in the form of a white powder, insoluble in cold water, whose size of the elementary particles ranges from 3 to 100 microns. This powder forms a gel when it is heated.
