Description

The present invention relates to the general field of compositions under

  form of powder that can incorporate a large amount of water and turn into liquid when applied to the skin, mucous membranes and / or hair. These compositions are also called water powders.

  The present invention thus relates to a new composition in the form of a powder comprising in combination at least one hydrophobic silica, water and at least one compound selected from the group consisting of xylitol, maltitol, sorbitol, erythritol, rhamnose, trehalose, arabinoxyloxane, and mixtures thereof. The subject of the invention is also a composition in powder form comprising, in combination, at least one hydrophobic silica having a BET specific surface area greater than or equal to 190 m2 / g and an average primary particle size of less than or equal to 10 nm, and the water. The invention also relates to the use of such compositions as vectors for active ingredients, the active ingredients being cosmetic, pharmaceutical or even perfume active ingredients.

  Several powder compositions incorporating a large quantity of water have been developed, but most of the compositions used up to now require the use of high amounts of silica and adjuvants, or require complex manufacturing processes. such as freezing or gelling water, to incorporate the aqueous phase within the powdery solid phase. Such compositions generally have low encapsulation yields. The application EP 1 206 928 thus describes compositions containing water, in the form of powder, consisting of aqueous gel cores coated with hydrophobic particles. In addition, the compositions of the prior art do not make it possible to encapsulate active agents of various natures of hydrophilic or lipophilic character and present problems of instability, during their manufacture or over time, such as exudation or release of water or problems of caking of the powder.

  Therefore, there was thus a need to develop a water powder, obtainable by a simple manufacturing process, and to solve the various problems encountered with the compositions of the prior art, and in particular to allow incorporating various active ingredients, of hydrophilic or lipophilic character, with a high encapsulation yield, making it possible to encapsulate a large quantity of water, having good stability during their manufacture as well as good stability over time after manufacture, and for efficiently delivering the actives incorporated into the composition on the skin, the mucous membranes and / or the hair, while providing a pleasant sensation, during the application of the composition.

  The present invention fills this need. The Applicant has thus surprisingly discovered that the following compounds: at least one hydrophobic silica, water, and at least one compound acting as a stabilizer such as trehalose, arabinoxyloxane, or xylitol, could be used in combination to incorporate various types of active ingredients, preferably cosmetic or pharmaceutical active ingredients, and in amounts greater than the amounts of active ingredients incorporated so far in the compositions of the prior art. The Applicant has thus discovered that a stabilizer such as xylitol used in combination with water and hydrophobic silica made it possible to obtain compositions in powder form having a stability greater than that of the compositions developed to date, and allowed thus to ensure better bioavailability and better release of assets when applying the product to the areas to be treated.

  The Applicant has also surprisingly discovered that the use of water in combination with a particular type of silica, namely a very hydrophobic silica having a specific surface area greater than or equal to 190 m 2 / g and a lower average primary particle size or equal to 10 nm, such as Aerosil R812S, also made it possible to solve the various problems of the compositions of the prior art and thus made it possible to obtain water powders with increased stability and having a high encapsulation efficiency of various active ingredients.

  The subject of the present invention is thus a composition in the form of a powder comprising in combination: (a) at least one hydrophobic silica, (b) at least one compound selected from the group consisting of xylitol, maltitol, sorbitol, erythritol, rhamnose, trehalose, arabinoxyloxane, and mixtures thereof, and (c) water.

  The hydrophobic silica (a ') according to the present invention advantageously has a coating based on hydrocarbon or silicone. Preferably, the silica is coated with a silicone-based coating, for example organosiloxane, polysiloxane, or silicone oil. By way of example, silicas such as trimethylsiloxylated, dimethylsiloxylated, octylsiloxylated silicas and silicas coated with silicone oil may be used. The size of the particles is typically between 0.01 and 40 m, advantageously between 0.01 and 20 m, even more advantageously between 0.01 and 10 m.

  According to a particular characteristic of the present invention, the hydrophobic silica (a ') is a trimethylsiloxylated silica.

  Advantageously according to the present invention, the silica (a ') has an average primary particle size of between 5 and 10 nm.

  In a particular embodiment of the present invention, the hydrophobic silica (a ') has a BET specific surface area of from 190 to 330 m 2 / g, advantageously from 190 to 290 m 2 / g, advantageously from 195 to 260 m 2 / g, advantageously from 195 to 245 m 2 / g, advantageously from 200 to 240 m 2 / g, still advantageously from 210 to 230 m 2 / g, more advantageously from approximately 220 m 2 / g, and a primary particle size of between 5 and 10 nm . In particular, the silica used is an Aerosil R812S silica or an Aerosil R812SVV60 silica produced by DEGUSSA AG. Aerosil R812S and Aerosil R812SVV60 are both hydrolytic products with 1,1,1-trimethyl-N- (trimethylsilyl) -silanamine SiO 2. The hydrophobic silica (a ') may be used alone or in combination with another hydrophobic silica, advantageously of the Aeroperl R806 / 30 or Aerosil R8200 type.

Aerosil R8200 silica, also marketed by DEGUSSA AG, has a specific surface area of between 135 and 185 m2 / g, typically about 160 m2 / g.

  The fact of using a particular hydrophobic silica (a ') having a specific surface area and an average size of particular primary particles makes it possible to incorporate a large quantity of water, as well as a large quantity of various types of active ingredients, within the composition according to the present invention, and also makes it possible to obtain a satisfactory stability during the manufacture of the composition, by a very simple industrial process consisting in exerting significant physical stresses on the liquid to force it to return to the within the powder, and satisfactory stability over time.
