Description

artificial tanning; or a hair composition.

  The present invention relates to a solid composition, generally an aqueous continuous phase, comprising: i) at least one first polysaccharide-type hydrophilic gelling agent and ii) at least one second soap-type gelling agent derived from the saponification of a fatty acid whose length of chain is greater than carbon atoms per molecule, intended to be applied to any keratin material, that is to say on the skin, including the scalp, and / or the lips of human beings, as well as its use in the cosmetic field, especially for makeup and / or care eVou perfuming eVou hygiene andiou the

sunscreen.

  The "ideal soil" used traditionally in the field of cosmetics or hygiene are solid forms, often made with waxes or with fatty substances, which can leave an impression of fatness in the application. or stain clothes, and they lack the freshness of the application, but more and more users are looking for a fresher

  especially in hot climates.

  We therefore seek more and more sticks comprising an aqueous phase in the largest possible concentration. However, the incorporation of the aqueous phase into solid compositions comprising an aqueous phase

  This can lead to problems of stability and lack of cohesion.

  Thus, US Pat. No. 6,042,815 describes solid compositions in the form of emulsions comprising from 5 to 95% of water and two gelling agents, the first of the carboxyl salt type, of which fatty acids are mentioned. and the second being selected from the very large family of gelling agents of aqueous or oily phase, including polysaccharides. The stability of such compositions is reported. Now, the Applicant has unexpectedly discovered that by combining a polysaccharide type gelling agent with a specific fatty acid soap, it is possible to produce stable, stable compositions which are easily disintegrated and which bring freshness and softness to the skin. the application. The selection of these gelling agents, among

  all possible combinations for the compositions described in USA-

  6,042,815, leads surprisingly to compositions with qualities

  cosmetics, including surface and feel, and hardness, improved.

  The present invention thus relates to a solid composition comprising: i) at least one first hydrophilic gelling agent of the polysaccharide type and ii) at least one second soap-type glycerizer derived from the saponification of an acid the

  Chain length is greater than 20 carbon atoms per molecule.

  Preferably, the composition according to the invention comprises water. So

  even more preferred, said composition is aqueous continuous phase.

  The compositions according to the invention provide for the application on keratin materials, in particular on the skin, a framer impression. They are particularly comfortable: they apply easily, bring a feeling of softness. They do not cause a feeling of tightness or dryness of the skin after application. They present excellent

cosmetic properties.

  The compositions of the invention have excellent application and disintegration qualities. In particular, thanks to the combination according to the invention, there is obtained, at equivalent hardness, a disintegration level higher than that of known sticks. Taking the product is easy, it can be done directly on the body or with the finger or sponge, by removing a sufficient amount of product, easy to apply on the skin or other keratin material homogeneously without prior mooring. The

  obtained makeup is uniform and homogeneous.

  These compositions also have excellent cohesion. They are stable over time and temperature. Thus, after having been stored for two months at room temperature or at 45 ° C. (for accelerated aging), they exhibit no syneresis (exudation) or phase shift phenomena.

  their appearance and their hardness have not changed.

  The compositions according to the invention do not exude, even at low levels of gelling agent, and they do not necessarily require the intervention of a technique

of particular preparation.

The pH of this stick is 9.

EXAMPLES 3 to 6

  The following comparative examples make it possible to highlight the interest of the invention. The sticky foundation of Example 1 served as a basis for comparison. Four examples were carried out according to the same method as in Example 1, replacing the sodium behenate associated with the gellan according to the invention with one or more other gelling agents which are gellan (alone), sodium stearate (only )

  Gellan / sodium stearate combination or sodium behenate (alone).

EXAMPLE 3

  Sodium stearate is the only gelling agent present, at a rate of 6%. A stick of pH = 9.36, hardness = 123 g, is obtained. After two months at room temperature or at 45 C, the hardness decreased to a value of 110 g. In conclusion, it is a stick of good hardness but very rough to the application, and whose pH is too high

EXAMPLE 4

  Sodium stearate and gellan are the gelling agents present at a level of 0.5% for gellan and 2% for sodium stearate. A stick of heterogeneous surface appearance, pH = 8.4, hardness = 20 g, is obtained. After two months

to the application.

  It is noted that, by comparing Examples 3 to 6 and Example 1, the sticks made with only soaps have high pH (strictly greater than 9), have a less homogeneous appearance and less smooth surface than the coupling soaps / polysaccharides according to the invention. On the other hand the cosmetic qualities are considered inferior, and the fracheur less, for the sticks made with

  only soaps compared to the sticks according to the invention.

  In addition, the stick made with the combination of polysaccharides and non-soap

  such as sodium stearate has a hardness that drops over time.

  The appearance is less satisfactory than the stick according to the invention.

  Finally, the sticks made according to the invention have a beautiful smooth and homogeneous appearance, cosmetic qualities such as softness and freshness, considered superior

to other associations.
