Description

SOLID AQUEOUS GEL COMPRISING A HYDROPHILIC GEL AND

STARCH, COMPOSITION INCLUDING IT,

USES

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 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.

Products which disintegrate well exist but they are often too soft and end up shearing during repeated applications or even present phenomena of syneresis over time, that is to say that the liquid part ends up s' exude 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.

Furthermore, there are aqueous gels comprising pigments: but we often then observe a phenomenon of sedimentation during manufacture, in particular during the cooling phase.

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 combining with a hydrophilic gelling agent a compound of a particular nature, namely a starch or its derivatives, 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 °) at least one starch or its derivatives.

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 provide a feeling of tightness of the skin when dry.

These gels are stable over time and at temperature. No phenomenon of pigment sedimentation is observed during manufacture, in particular during the cooling phase. In addition, after having been stored for two months at room temperature or at 45 ° C, these gels 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 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.

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,

The gel according to the invention also comprises a starch or one of its derivatives.

The starches and its derivatives which can be used in the present invention are more particularly macromolecules in the form of polymers consisting of elementary units which are anhydroglucose units. The number of these units and their assembly make it possible to distinguish amylose (linear polymer) and amylopectin (branched polymer). The relative proportions of amylose and amylopectin, as well as their degree of polymerization, vary according to the botanical origin of the starches.

The starches used in the present invention can have, as botanical origin, cereals or tubers. Thus, the starches are for example chosen from starches of corn, rice, cassava, potato, wheat, sorghum, peas, native (that is to say unmodified) or modified. Among the modified starches, mention may be made of precooked starches, hydrolyzed starches, crosslinked starches, for example with a methylol urea derivative or with octenyl succinic anhydride or also with epichlorohydrin, esterified starches, etherified starches, oxidized starches, refined starches, starches roasted in the presence of acid, or even starches grafted, for example with sodium polyacrylates, starches coated, for example with amino acids, and / or mixtures thereof.
