Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates to solid aqueous gels, solid compositions containing an aqueous continuous phase containing such gels and their use in cosmetics, in particular for making up skin and / or mucous membranes and / or keratin fibers.

[0002]

[Prior art]

Products in solid form are known in the cosmetics industry. Products which may be mentioned as products of this type include, for example, in the make-up field lipsticks, foundations or eyeshadow tubes or "sticks"; in the skin-care or lip-care field, lip-restoring pencils and depigments. , Tubes for make-up removal or moisturizing or "sticks"; in the field of hygiene,
Includes deodorant sticks and foaming sticks or bars for shaving or cleaning the skin.

In fact, stick-shaped products are very practical, easy to transport,
The stick form of the product is particularly advantageous as the product does not run out.

Furthermore, make-up products are generally based on the one hand on the fat phase for comfort and smoothness and on the other hand in the powder phase which gives the desired color. This powder phase can contain pigments and / or fillers and / or nacres. The fatty phase generally contains waxes and / or oils and / or pasty compounds.

However, sticks formulated on a wax basis have distinct drawbacks. These have a greasy property that the user does not find attractive and lack freshness when applied. Furthermore, it is difficult to introduce a hydrophilic activator here.

[0006]

[Problems to be Solved by the Invention]

Therefore, it is increasingly desired to produce make-up sticks which contain the water phase in the highest possible content. Of course, non-greasy sticks such as deodorant sticks have already been produced, but these sticks rarely contain pigments or pearlescent substances.

It has been found here that the presence of pigments or nacres in aqueous sticks leads to decomposition of the product, ie a problem in removing the product:
Notably, these pigments and / or nacres are solid particles which are essential for the coloring of the composition, but are not dissolved in the final composition. However, they tend to impair the stability of the composition.

Furthermore, especially for make-up products, the ideal removal of the product can be achieved, ie by using a finger or a sponge or directly on the skin surface of the body, by a simple method, for example: It is essential not only to take out an appropriate amount of product (not enough to waste the product, but to give a sufficient make-up effect), and to maintain the complete condition of the product at the time of taking it out. Is important to. The product must not be destroyed by the action of shear, pigments and / or nacres,
And / or the entire product, optionally including a filler that provides a make-up function, should be accurately dispensed. Only under these conditions the application of the product is uniform and the makeup effect obtained is uniform.

Although there are products that are accurately separated, they are often too soft and
After repeated application or such synergic syneresis, it will be sheared. That is, the liquid portion will exude, and the product will separate into two phases, an inseparable solid phase and a liquid phase. The product can no longer fulfill its purpose, ie the application of make-up, since it is not possible to take out the pigment into the finger or sponge.

Furthermore, there are aqueous gels containing pigments. However, in this case, precipitation phenomena are often observed during manufacture, especially during the cooling period.

Further, aqueous stiff gels are disclosed in WO 97/17055. However, these gels require the use of fairly high concentrations of gelling agent or a particular preparation technique, extrusion. Furthermore, due to the high concentration of gelling agents, these sticks lack a refreshing feel and smoothness on application.

In order to overcome these separation problems, it has been proposed to introduce fillers with specific chemistries into these gels, for example silica or nylon. However, the product thus obtained is of very poor cosmetic quality, has a rough feel, and gives discomfort, such as dryness or tautness, when the product is applied to the skin. They are also difficult to apply when pigments are present. Therefore, there is a need for a solid aqueous gel that does not have the conventional drawbacks.

[0013]

Means for Solving the Problems and Embodiments of the Invention

Applicants have unexpectedly been able to prepare a solid aqueous gel, optionally containing pigments and / or nacres, by combining a hydrophilic gelling agent with a compound of a particular nature, namely starch or starch derivatives. It has been found that these gels can be easily dispensed with a finger or sponge, or directly on the skin surface of the face or body, and these gels have outstanding cosmetic quality.

[0014]   Thus, the present invention provides i) at least one hydrophilic gelling agent, and ii) at least one starch or starch derivative, It is a solid aqueous gel containing.

These gels have an unrivaled cosmetic quality and improve the comfort and smoothness of the film after drying on the skin surface. The film does not give a dry or taut feel when dried.

These gels are stable over time and thermally stable. No pigment precipitation is observed during manufacture, especially during the cooling period. Furthermore, ambient temperature or 45 ° C
After 2 months of storage in these gels, the phenomenon of phase separation or syneresis (exudation) was observed in these gels.
Are not seen at all, and their appearance and hardness are unchanged.

The gel according to the invention does not exude even when it has a low content of gelling agent and does not require the mandatory intervention of specific preparation techniques. When applied, it gives a very refreshing feel while maintaining good cosmetic properties, especially smoothness.

The gels of the invention have an outstanding coating and dispensing quality. In particular, the level of split obtained with the combination according to the invention for comparable hardness is superior to the known sticks. The product is easy to remove and this can be done directly on the body surface or by taking a sufficient amount of the product with a finger or a sponge, without the need for pre-moistening and on the skin. Easy to apply homogeneously. The gel easily extends to the skin surface. The makeup effect obtained is uniform and homogeneous.
