Reflective particles that can be used in the invention, with a metallic or white sheen, can for example reflect light in all visible components without significantly absorbing one or more wavelengths.

This method according to the invention allows in particular the care or makeup of the lips, by applying a composition of lipstick or lip gloss (gloss) according to the invention.

  The present invention also relates to a cosmetic assembly comprising: a container defining at least one compartment, said container being closed by a closure element; and a composition as described previously disposed inside said compartment. The container may be in any suitable form. It may especially be in the form of a bottle, a tube, a pot, a case, a box, a bag or a case.

  The closure element may be in the form of a removable cap, a lid, a lid, a tearable strip, or a capsule, in particular of the type comprising a body fixed to the container and a cap. articulated on the body. It may also be in the form of an element ensuring the selective closure of the container, in particular a pump, a valve, or a valve.

  The container may be associated with an applicator, in particular in the form of a brush comprising an arrangement of bristles held by a twisted wire. Such a twisted brush is described in particular in US Pat. No. 4,887,622. It may also be in the form of a comb comprising a plurality of application elements, obtained in particular from molding. Such combs are described for example in patent FR 2 796 529. The applicator may be in the form of a brush, as described for example in patent FR 2 722 380. The applicator may be in the form of a block of foam or elastomer, felt, or spatula. The applicator may be free (puff or sponge) or integral with a rod carried by the closure member, as described for example in US Patent 5,492,426. The applicator may be integral with the container, as described for example the patent FR 2 761 959.

  The product can be contained directly in the container, or indirectly. By way of example, the product may be placed on an impregnated support, in particular in the form of a wipe or a tampon, and arranged (individually or in several) in a box or in a bag. Such a support incorporating the product is described for example in the application WO 01/03538.

  The closure member may be coupled to the container by screwing. Alternatively, the coupling between the closure member and the container is other than by screwing, in particular via a bayonet mechanism, snap-fastening, clamping, welding, gluing, or magnetic attraction. By "latching" is meant in particular any system involving the crossing of a bead or a bead of material by elastic deformation of a portion, in particular of the closure element, then by return to the position not elastically constrained of said portion after crossing the bead or cor-don.

  The container may be at least partly made of thermoplastic material. Examples of thermoplastic materials include polypropylene or polyethylene. Alternatively, the container is made of non-thermoplastic material, in particular glass or metal (or alloy).

  The container may have rigid walls or deformable walls, in particular in the form of a tube or a tube flask.

  The container may include means for causing or facilitating the dispensing of the composition. By way of example, the container may have deformable walls so as to cause the composition to exit in response to an overpressure inside the container, which excess pressure is caused by elastic (or non-elastic) crushing of the walls of the container. . Alternatively, especially when the product is in the form of a stick, the latter can be driven by a piston mechanism. Still in the case of a stick, in particular makeup product (lipstick, foundation, etc.), the container may comprise a mechanism, including rack, or with a threaded rod, or with a helical ramp, and able to move a stick towards said opening. Such a mechanism is described, for example, in patent FR 2 806 273 or in patent FR 2 775 566. Such a mechanism for a liquid product is described in patent FR 2 727 609.

  The container may consist of a housing with a bottom defining at least one housing containing the composition, and a cover, in particular articulated on the bottom, and adapted to cover at least part of said bottom. Such a housing is described, for example, in claim WO 03/018423 or in patent FR 2 791 042.

  The container may be equipped with a wiper arranged in the vicinity of the opening of the container. Such a wiper makes it possible to wipe the applicator and possibly the rod which it can be secured. Such a wiper is described, for example, in patent FR 2 792 618.

  The composition may be at atmospheric pressure inside the container (at room temperature) or pressurized, in particular by means of a propellant (aerosol). In the latter case, the container is equipped with a valve (of the type used for aerosols).

  The invention is illustrated in more detail in the following examples. Method of measuring viscosity

  The viscosity at 80 ° C. or at 110 ° C. of the polymer is measured using a planar cone viscometer of the BROOKFIELD CAP 1000+ type. The adapted cone-plane is determined by the person skilled in the art, on the basis of his knowledge; in particular: - between 50 and 500 mPa.s, one can use a cone 02 - between 500 and 1000 mPa.s: cone 03 20 - between 1000 and 4000 mPa.s: cone 05 - between 4000 and 10000 mPa.s: cone 06
