Definitions

  • Compact powder comprising polyamide particles containing an active agent
  • the present invention relates to an anhydrous cosmetic composition, especially in the form of a compact powder, comprising: a pulverulent phase comprising polyamide particles; a fatty phase; and at least one moisture-sensitive cosmetic or pharmaceutical active agent, characterized in that the said particles have a mean volume diameter of less than or equal to 10 ⁇ m and contain at least a fraction of the active agent, and in that the fatty phase represents from 0.1% to 20% by weight of the composition.
  • the invention also relates to a cosmetic process for caring for greasy skin or for bleaching the skin, comprising the topical application to the skin of the abovementioned composition.
  • Compact care or makeup face powders are anhydrous compositions that generally comprise, on the one hand, a pulverulent phase especially comprising pigments and/or fillers (such ,as ⁇ polyamide particles) and, on the other hand, a fatty phase as binder comprising fatty substances, which is intended to give the finished product a certain density, to give the product softness and an emollient nature and to promote its adhesion to the skin.
  • These compact powders are generally intended for making up the skin, to give it a healthy appearance or to efface surface defects, or to make the surface of the skin matt by absorbing the excess sebum.
  • the Applicant has now demonstrated that by trapping these active agents in nylon particles, it is possible to avoid their degradation in a humid environment.
  • the nylon particles are moreover capable of being compacted, unlike particles of other materials, for instance silica.
  • the encapsulated active agents can enter the pilosebaceous follicles, down to their site of action, and thus act more efficiently. This therefore avoids losses of active agent in the upper layers of the epidermis and in particular on the surface of the skin where it is liable to degrade.
  • compositions that may be anhydrous or in powder form, comprising a porous support, for example made of polyamide, on or in which is adsorbed an active agent, such as vitamin C, the support having any particle size or a size such that the active agent remains on the surface of the skin (thus greater than 10 ⁇ m) .
  • Patent application WO 98/58628 also discloses anhydrous bleaching compositions, optionally in powder form, which deliver active agents to the stratum corneum, the upper layer of the epidermis.
  • These compositions contain a depigmenting agent (kojic acid), and also an exfoliant, in particular salicylic acid, adsorbed onto or in a support material such as a polyamide with a particle size of less than 20 ⁇ m, but preferably such that the exfoliant does not enter the pilosebaceous follicles, i.e. generally greater than 10 ⁇ m.
  • the particles of the support material have the function of protecting the exfoliant in the event of incompatibility with other active agents of the composition.
  • They contain the exfoliant, optionally in a form dissolved or dispersed in a hydrophilic support medium such as water, an alcohol or an ether.
  • Example 4 of patent application WO 98/58628 thus discloses an anhydrous composition containing kojic acid, and also nylon beads filled with lactic acid mixed with glycerol.
  • This composition contains more than 65% by weight of fatty phase, which creates a protective medium with respect to ambient moisture and thus avoids the degradation of the moisture-sensitive active agents. However, it does not have the powdery feel of a compact powder.
  • the HAPPI database discloses an anhydrous face powder containing 8.75 weight percent of binding agents and powders, among which Orgasol 2002 N5 HY COS which has a size of 5 ⁇ m and contains hyaluronic acid.
  • Orgasol 2002 N5 HY COS which has a size of 5 ⁇ m and contains hyaluronic acid.

  • sticks containing Nylon powder of 10 ⁇ m (Orgasol 1002 EXD WEISS 10 COS) charged with octoxyglycerine.
  • the active agents contained in the Nylon particles disclosed in these two publications are either carried in water, or swellable in water, and are not considered moisture-sensitive active agents in the meaning of the present invention. There is thus still a need for a composition that may be used as a compact powder and in which moisture-sensitive active agents will be protected against degradation.

  • a subject of the invention is also a cosmetic process for caring for greasy skin or for bleaching the skin, comprising the topical application to the skin of the abovementioned composition.
  • a subject of the invention is also the use of this composition for the manufacture of a dermatological preparation for depigmenting the skin.

They are preferably spherical, or substantially spherical, and have a mean numerical diameter of less than or equal to 10 ⁇ m and advantageously between 0.5 and 10 ⁇ m. Their specific surface area, measured by the BET method, is generally greater than 1 m 2 /g.
  • the BET (Brunauer-Emmet-Teller) method is a method that is well known to those skilled in the art. It is described especially in "The Journal of the American Chemical Society", vol. 60, page 309, February 1938 and corresponds to international standard ISO 5794/1 (appendix D) .
  • the specific surface area measured according to the BET method corresponds to the total specific surface area, i.e. it includes the area formed by the pores.

  • the polyamide particles may, where appropriate, be surface-treated with at least one hydrophobic treatment agent, which is especially non- fluorinated, so long as they remain porous.
  • This hydrophobic treatment agent may especially be chosen from: silicones, for instance, methicones or dimethicones; fatty acids, for instance stearic acid; metal soaps, for instance aluminium dimyristate or the aluminium salt of hydrogenated tallow glutamate; amino acids, N-acylamino acids or salts thereof; lecithin or isopropyl triisostearyl titanate; and mixtures thereof.

  • the particles containing the active agent may be obtained according to an impregnation process comprising the following steps: - dissolution of the active agent to be encapsulated in an organic solvent with a boiling point lower than that of water at atmospheric pressure, such as acetone, isopropanol, dichloromethane or ethanol, to obtain an impregnation solution, impregnation of the polyamide particles with the said impregnation solution, evaporation of the solvent until a dry powder is obtained.
  • This process allows the production of particles which, once introduced into an anhydrous composition, will not be liable or will only be sparingly liable to release the active agent they contain.
