Description

SOLID AQUEOUS GEL COMPRISING A HYDROPHILIC GELLANT AND SPECIAL CHARGES

The present invention relates to a solid aqueous gel, a solid composition with an aqueous continuous phase comprising such a gel and their use in the cosmetic field, in particular for making up the skin and / or mucous membranes and / or keratin fibers.

Products 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, of sticks or “sticks” of lipstick, foundation or eye shadow; in the field of skin or lip care, lip repair pencils, depigmenting, make-up removing or moisturizing sticks or "sticks"; in the field of hygiene, deodorant sticks, sticks or foam bars for shaving or for washing the skin.

It is in fact particularly advantageous to have products in the form of sticks insofar as such products are very practical to use, they are easily transportable, the product is not likely to leak.

Furthermore, makeup products are fairly generally formulated on the one hand on the basis of an oily phase for reasons of comfort and softness and on the other hand on a pulverulent phase which provides the desired color. This pulverulent phase can comprise pigments and / or fillers and / or nacres. The fatty phase generally comprises waxes and / or oils and / or pasty compounds.

However, the sticks formulated based on waxes have certain disadvantages: they have a fatty character which is not appreciated by the users and they lack freshness on application. In addition, it is difficult to introduce hydrophilic active agents into it.

It is therefore increasingly sought to make makeup sticks comprising an aqueous phase in the greatest possible concentration. It is of course known to make non-greasy sticks such as deodorant sticks but the latter rarely contain pigments or nacres.

However, it turns out that the presence of pigments or nacres in aqueous sticks leads to problems of disintegration of the product, that is to say of taking the product: in fact, these pigments and / or these nacres, essential make-up products to bring color are solid particles which are not dissolved in the final composition. Therefore they are likely to interfere with the stability of the latter.

Furthermore, it is essential, for a makeup product in particular, that the removal of the product be carried out in an ideal manner, that is to say, allows, in a simple manner, using the finger or a sponge. or even directly on the skin of the body for example, to take not only the quantity of adequate product (not too much not to lose product unnecessarily but enough to ensure a makeup effect) but also to preserve the integrity of the product at the time of its removal: the product must not be broken by a shearing phenomenon, but the entire product must be removed with the pigments and / or pearlescent agents, and / or possibly the fillers, which ensure the function of the makeup. It is only under this condition that the application of the product can be done in a homogeneous manner and that the makeup obtained will be uniform.

Stable solid aqueous gels comprising pigments are known: but these products are generally impossible to disintegrate; they are often brittle, so it is impossible to take the product on the finger or on a sponge. Such products do not allow the deposition of a homogeneous film on the skin. Breakable products also exist but they are then too soft and end up shearing during repeated applications or even exhibit phenomena of syneresis over time, that is to say that the liquid part ends up exuding and the product has two phases: an indelible solid phase and a liquid phase. The product can no longer ensure its function, namely, make up, since it is impossible to take the pigments on the finger or on a sponge.

In addition, rigid aqueous gels are described in document WO-A-97/17055. However, these gels require the use of a fairly high concentration of gelling agent or use a special preparation technique, extrusion. In addition, these sticks, due to the high concentration of gelling agent, lack freshness and softness when applied to the skin.

To remedy these disintegration problems, it has been proposed to incorporate in these gels fillers 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, provide feelings of discomfort such as drying or tightness once the product is deposited on the skin. They also have difficult application qualities in the presence of pigments.

Also, there remains the need for a solid aqueous gel, not having the drawbacks of the prior art.

The Applicant has unexpectedly discovered that by associating with a hydrophilic gelling agent a filler of a particular nature, namely a filler with deformable particles, it was possible to produce solid aqueous gels optionally comprising pigments and / or nacres, these gels can be easily disintegrated with a finger or a sponge or directly on the skin of the face or body and having remarkable cosmetic qualities. The present invention therefore relates to a solid aqueous gel comprising i) at least one hydrophilic gelling agent and ii) a pulverulent phase comprising at least one filler with deformable particles, the hydrophilic gelling agent being present in the gel at a content less than or equal to 20% by weight, relative to the total weight of the gel.

The gels of the invention have excellent application and disintegration qualities. In particular, thanks to the combination according to the invention, a level of disintegration higher than that of known sticks is obtained, at equivalent hardness. Taking the product is easy, it can be done directly on the body or with the finger or even with a sponge, taking a sufficient amount of product, easy to apply then on the skin evenly, without the need for wetting prior. The gel spreads easily on the skin. The makeup obtained is uniform and homogeneous.

These gels have excellent cosmetic qualities: the comfort and smoothness of the film after drying on the skin are improved. This film is non-drying and does not give a feeling of tightness when dry.

These gels are stable over time and at temperature. Thus, after having been stored for two months at room temperature or at 45 ° C, they show no phenomenon of syneresis (exudation) or even phase shift: their appearance and hardness have not varied.

The gels according to the invention do not exude, even at low levels of gelling agent, and they do not necessarily require the intervention of a particular preparation technique. They give the application a feeling of great freshness while retaining good cosmetic properties, in particular of softness.

The present invention also relates to a solid composition with an aqueous continuous phase comprising a gel as defined above. The present invention also relates to a product for making up the skin or keratin fibers comprising a gel and / or a composition as defined above.

The present invention also relates to a process for making up the skin and / or mucous membranes and / or keratin fibers, consisting in applying to the latter, an aqueous gel and / or a solid composition and / or a make-up product such as defined above.

For the purposes of the present invention, the term “gel or solid composition” means a gel or composition having a hardness defined by a maximum force before rupture ranging from 5 to 50 grams, at room temperature (20-25 ° C.), after penetration by a 2 mm diameter stainless steel mobile in the gel matrix or composition at a thickness of 1 mm at a speed of 1 mm / s and removal of said mobile from the gel matrix or composition at a speed of 2 mm / s; the maximum force before rupture being measured with a texture analyzer of the "TAXT2" type sold by the company RHEO.

More preferably, the maximum force before rupture ranges from 7 to 40 g.

The gel according to the invention comprises a hydrophilic gelling agent. By gelling agent, is meant a compound which, in the presence of a solvent, creates more or less strong intermacromolecular bonds thus inducing a three-dimensional network which freezes said solvent.

This hydrophilic gelling agent can be chosen from polysaccharides, protein derivatives, synthetic or semi-synthetic gels of polyester type, polyacrylates or polymethacrylates and their derivatives.

Among the polysaccharides, there may be mentioned: - seaweed extracts such as agar-agar, carrageenans (iota, kappa, lambda), alginates, in particular Na or Ca;

- exudates from microorganisms such as xanthan gum and its derivatives such as the product sold under the trade name "Rhéosan" by the company Rhodia Chimie, gellan,

- fruit extracts such as pectins;

- gelling agents of animal origin such as protein derivatives, in particular gelatin, beef or fish, casemates;

the polysaccharides having a side chain and 6 neutral sugars as described in the document FR-A-2759377,

- and their mixtures.

Preferably, the hydrophilic gelling agent is chosen from polysaccharides, and more preferably, the hydrophilic gelling agent is gellan.

As products which are particularly suitable for the invention, there may be mentioned gellan gum sold under the trade name “Kelcogel F” by the company NUTRASWEET-KELCO or else iota carraghenane sold under the trade names “Seaspen PF 357” or “Viscarin SD 389 "by FMC.

The hydrophilic gelling agent is present in the gel according to the invention at a concentration of up to 20% by weight, and of _. preferably 0.2 to 10%, by weight, relative to the total weight of the gel. This concentration makes it possible to obtain the hardness and consistency suitable for an ideal crumbling.

The gel according to the invention also comprises a pulverulent phase which comprises at least one filler with deformable particles.

By fillers, it is necessary to understand colorless or white particles, mineral or synthetic, spherical or non-spherical, intended to give body or rigidity in composition, and / or softness, matness and uniformity in make-up.

By filler with deformable particles is meant, within the meaning of the present invention, spherical particles or not of sufficiently low hardness to deform when the composition is removed using a finger or a sponge or directly by friction on the skin when it is a stick. In particular, by "deformable", it should be understood that the particles are flexible and elastic: after crushing, they return to 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 an example of solid deformable particles, there may be mentioned particles of crosslinked organosiloxane or “silicone rubber powder” as described in document JP 10 175816, the JIS A hardness of which is equal to or less than 80 and preferably less than 65 These particles can be coated with surfactant or a fine organic powder. They may also contain a non-crosslinked silicone or hydrocarbon oil which may exude "silicone rubber powder".

Mention may be made of the 63% silicone rubber powder in aqueous dispersion sold under the trade names "BY29-119" "BY-29-122" by Dow Corning.

The solid deformable particles which can be used according to the present invention preferably have a density ranging from 0.8 to 4, more preferably ranging from 0.8 to 1.5.

When the deformable particles are hollow or filled with gas or air, they advantageously have a density ranging from 0.015 to 0.2 and better still greater than 0.04 and / or less than 0.1 and in particular ranging from 0.06 to 0.08.

One can, for example, 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, relative to the weight total of the copolymer of units derived from acrylonitrile and from 1% to 50% by weight, relative to 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 are present in particular in the dry or hydrated state.

This copolymer is non-toxic and non-irritating to the skin.

Preferably, the hollow particles are in the form of microspheres and have an average size or particle size ranging from 10 μm to 60 μm.

The hollow particles of the invention can be obtained, for example, according to the methods of patents and patent applications EP-56 219, EP-348 372, EP-486 080, EP-320473, EP-112 807 and US-3 615,972.

The internal cavity of the particles in principle contains a gas which can be air, nitrogen or a hydrocarbon such as isobutane or isopentane.

The hollow particles which can be used in the invention are in particular those sold under the brand name Expancel by the company Casco Nobel such as the Expancel 551 DE 20 with a particle size of 27 μm and a density of about 0.052, the Expancel 551 DE 80 with a particle size of 50 μm and density approximately 0.045, Expancel 051 DE with a particle size of 30 μm and density approximately 0.056, Expancel 461 DE with a particle size of 30 μm and density approximately 0.058, Expancel 551 DE 12 with a particle size of 17 μm and density approximately 0.07, or again the Expancel of the "W" series such as the Expancel 551 W 20 with a particle size of 27 μm and a density of about 0.033.

Preferably, the fillers with deformable particles are present in the gels according to the invention at a content ranging from 0.1 to 50% by weight relative to the weight of the gel. This content can vary, in particular depending on the density of the load with deformable particles. Thus, when this filler has a density ranging from 0.015 to 0.2, then it is preferably present at a content ranging from 0.1 to 10% by weight, by weight, relative to the total weight of the gel. When this filler has a density ranging from 0.8 to 4, then it is preferably present at a content ranging from 1 to 50%, by weight, relative to the total weight of the gel.

For example, for hollow deformable particles such as the Expancels mentioned above, this content generally ranges from 0.1% to 10% by weight of particles and better still from 0.3% to 5% by weight and again from 0.3 % to 2%, based on the total weight of the gel.

The pulverulent phase can comprise, in addition to the fillers with deformable particles mentioned above, other fillers, which can be mineral or synthetic, lamellar or non-lamellar, as well as pigments and / or nacres.

Thus, preferably, the aqueous gel according to the invention is not transparent, that is to say that the characters of a newspaper page cannot be seen through the gel. More preferably, it is not translucent, that is to say that it does not allow the passage of light.

The pulverulent phase preferably comprises from 0.1 to 40%, more preferably from 0.1 to 20% by weight, relative to the total weight of the gel, of pigments and / or nacres.

It is possible to modify the rigidity of the gels according to the invention by adding one or more salts which will increase this rigidity. These salts can be chosen from the mono-, di- or trivalent metal salts, and more particularly the alkali and alkaline-earth metal salts and in particular the sodium, calcium or magnesium salts. The ions constituting these salts can be chosen, for example, from carbonates, bicarbonates, sulfates, glycerophosphates, borates, chlorides, nitrates, acetates, hydroxides, persulfates as well as the α-hydroxy acid salts ( citrates, tartrates, lactates, malates) or fruit acids, or the amino acid salts (aspartate, arginate, glycocholate, fumarate).
