Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a solid aqueous gel, a solid composition having a continuous aqueous phase containing said gel, and its use in the cosmetics field, in particular for making up skin and / or mucous membranes and / or keratin fibres.

[0002]

[Prior art]

Products that exist in solid form are well known in the cosmetics industry. Products of this type which may be mentioned by way of example are lipsticks, foundations or eye shadow sticks, for example in the field of makeup; lip repair pencils, and bleaching, make-up removal or moisturizing sticks in the field of skin care or lip care; In the field it includes deodorant sticks and forming sticks or bars for shaving or cleaning the skin.

Basically, it is particularly useful to have available products in stick form, as long as the above products are very convenient for use and risk-free and easily portable.

Furthermore, make-up products are generally formulated on the basis of a fatty phase, firstly for reasons of comfort and softness, and secondly a powdery phase which provides the desired color. The powder phase is
It may also contain pigments and / or fillers and / or nacreous substances. The fatty phase generally comprises waxes and / or oils and / or pasty compounds.

However, sticks formulated on a wax base have certain drawbacks; they have greasy characteristics that are not expected by the user, and they lack freshness on application. Moreover, it is difficult to incorporate active hydrophilic substances therein.

Therefore, attempts to produce make-up sticks containing an aqueous phase in the highest possible concentration are being accelerated. The manufacture of non-greasy sticks, such as deodorant sticks, is of course well known, but the latter contains little pigment or nacreous material.

However, the presence of pigments or nacreous substances in aqueous sticks has been found to give rise to problems with the product's cosmetic paste, ie the application of the product;
These pigments and / or nacreous materials are present as solid particles that do not disperse in the make-up product to provide color and do not dissolve in the final composition. Because of this, they tend to interfere with the stability of the composition.

Furthermore, a requirement, in particular for make-up products, is that the product is most preferably applied with the aid of a finger or a sponge or directly on the skin of the body, ie easy to apply, for example the product Appropriate amount (not too much to waste the product, but enough to get a make-up effect) must be applied as well as the product integrity must be preserved at the time of application What is needed is a pigment and / or nacre material, and / or a filler, if present, which, instead of breaking the product as a result of the shearing phenomenon, instead provide a make-up function, The whole product can be applied. Only if this condition is met, the product can be applied homogeneously and a uniform application of make-up can be obtained.

Stable solid aqueous gels containing pigments are well known: however, it is generally not possible to stick to these products; they are generally fragile and therefore place the product on a finger or sponge. It is impossible to apply. The product is unable to deposit a homogeneous film on the skin.

Good-to-make products also exist, but they are too soft and disappear by shearing during the course of repeated application, or over time the phenomenon of syneresis, ie the liquid part does not ooze out and the product Two-phase: Shows a phenomenon that exists in a solid phase and a liquid phase with poor paste. The product can then no longer perform its function, especially the make-up function, because the pigment cannot be applied to the finger or sponge.

Furthermore, aqueous viscous gels are described in the document WO-A-97 / 17055. However, these gels require the use of very high concentrations of gelling agents and require specific preparation methods,
Use the extrusion method. Moreover, these sticks lack the freshness and softness when applied to the skin due to the high concentration of gelling agent.

In order to overcome these cosmetic sticking problems, it has been proposed to incorporate in these gels fillers with specific chemical properties such as silica or nylon. However, the products thus obtained have significantly poor cosmetic properties: they are rough to the touch and, once the product has been deposited on the skin, give rise to unpleasant sensations such as dryness or tension. Furthermore, they are difficult to apply in the presence of pigments.

[0013]   Therefore, there is a need for a solid aqueous gel that does not have the disadvantages of the prior art.

[0014]

[Problems to be Solved by the Invention]

Applicants anticipate that by combining hydrophilic gelling agents with certain types of fillers, in particular fillers with deformable particles, solid aqueous gels, optionally containing pigments and / or nacreous materials, can be realized. Undiscovered, it was discovered that these gels could be easily applied with fingers or sponges or directly to the skin of the face or body and had outstanding cosmetic properties.

[0015]

[Means for Solving the Problems]

The invention thus provides a solid aqueous gel comprising a powder phase comprising i) at least one hydrophilic gelling agent and ii) at least one filler having deformable particles, the hydrophilic gelling agent comprising , In the gel in an amount of up to 20% by weight, based on the total weight of the gel.

The gel of the present invention exhibits excellent cosmetic paste and application properties. In particular, the combination according to the invention gives a level of make-up paste of comparable hardness, which is greater than that of the known sticks. The product is easy to apply and may be applied directly to the human body or with a finger or sponge to give a sufficient amount of the product and to the skin in a homogeneous manner without the need for subsequent pre-moistening. . The gel is easily spread on the skin. The make-up obtained is uniform and homogeneous.

These gels show excellent cosmetic properties: after drying the skin, the comfort and softness of the coating are improved. The film does not dry and does not feel tight once a day.

These gels are stable over time and with temperature. Thus, after maintaining at ambient temperature or at 45 ° C. for 2 months, they show no phenomenon of syneresis or phase separation: their appearance and hardness are unchanged.

The gels according to the invention are not extruded even with low gelling agent content, they do not necessarily require the use of a particular preparation method. Upon application, they produce a noticeably fresh sensation while maintaining good cosmetic properties, especially softness.

The present invention further provides a solid composition having a continuous aqueous phase comprising the gel described above.

The present invention further provides a make-up product for skin or keratin fibres, which comprises a gel and / or a composition as described above.

The present invention further provides a method of making up skin and / or mucous membranes and / or keratin fibers, which comprises applying a solid aqueous gel and / or solid composition and / or make-up product as described above. .
