ABSTRACT:
The present invention relates to a cosmetic composition for the grainy making up of keratinous substances comprising a film-forming polymer and particles, and to a make-up kit comprising the composition. Another subject matter of the invention is a cosmetic process for making up keratinous substances. The composition according to the invention can be applied to the nails, to the skin, both of the face and of the body, including the lips, and to the hair, in particular of human beings. More specifically, the invention relates to a nail varnish.
The make-up composition can be a nail varnish, a face powder, an eye shadow, a foundation, and a make-up product for the lips or a product for making up the body. The composition can also be applied to make-up accessories, such as false nails, false eyelashes, false wigs, or to discs or patches, which adhere to the skin or lips (of the beauty spot type).
Nail varnish compositions generally comprise a film-forming polymer, either dissolved in an organic solvent or dispersed in the form of particles in an aqueous medium, and a colouring material, in particular a pigment. Such varnishes are disclosed, for example, in U.S. Pat. No. 4,158,053 and French Patent No. 2,578,741, the disclosures of both of which are hereby incorporated by reference.
These nail varnishes, after application to the nail of one or more layers of the composition and after drying, generally result in the formation of a glossy or matt, smooth, continuous and homogeneous film. Some films also exhibit good cosmetic smooth, continuous and homogeneous film. Some films also exhibit good cosmetic properties, such as good hold, and in particular good adhesion to the nail and good resistance to water, to rubbing movements and to impacts.
With changing fashion, consumers, who are increasingly demanding, are looking for novel make-up products that confer original or specific make-up effects. A need therefore remains to have available a make-up product which, when applied to a substrate, such as human nails, skin or hair, results in a make-up effect different from those of the smooth, continuous and homogeneous films currently obtained with the commercially available products.
An aim of the present invention is therefore to provide a make-up composition that makes it possible to obtain an in-relief make-up on keratinous substances while exhibiting good hold over time. The make-up confers a grainy or “roughcast” appearance on the substrate where it is applied.
The Inventor has found that a novel type of make-up for keratinous substances can be obtained by using a film-forming composition comprising specific fragments of colored film.
More specifically, an embodiment of the invention is a cosmetic make-up composition comprising, in a cosmetically acceptable medium, a film-forming polymer and a coloring material, wherein the coloring material comprises a colored polymer film fragment which exhibits two substantially flat faces, which has a thickness ranging from 40 to 200 &mgr;m and which has a larger dimension ranging from 0.1 to 4 mm, the fragment being insoluble in the medium of the composition.
When the composition is applied to keratinous substances, such as the nails, the film fragments are easily distributed in the deposited layer and are arranged well in the thickness of the layer. This composition provides a make-up film exhibiting parts, distributed randomly at the surface of the film, which are thicker than the mean thickness of the film. The surface of the make-up film exhibits a noncontinuous relief that is resistant to rubbing movements. An original in-relief make-up, original both to the touch and to the eye, is thus obtained which exhibits good adhesion to the made-up substrate and good hold.
This composition can advantageously be applied as a surface product, commonly known as a top coat.
Another embodiment of the invention is a cosmetic process for making up keratinous substances which comprises applying, to the keratinous substances, a composition as defined above.
Another embodiment of the invention is a cosmetic process for making up keratinous substances which comprises applying, to the keratinous substances, a first layer, also known as the base layer, of a first cosmetic composition comprising, in a cosmetically acceptable medium, a first film-forming polymer and in then applying, to at least a portion of the first layer, a second layer, also known as the surface layer, of a second cosmetic composition comprising, in a cosmetically acceptable medium, at least one second film-forming polymer and at least one colored polymer film fragment which exhibits two substantially flat faces, which has a thickness ranging from 40 to 200 &mgr;m and which has a larger dimension ranging from 0.1 to 4 mm, the fragment being insoluble in the medium of the composition, the first composition not comprising a polymer film fragment as present in the second composition.
Another embodiment of the invention is a make-up kit comprising:
a first cosmetic composition (base layer composition) comprising, in a cosmetically acceptable medium, a first film-forming polymer;
a second cosmetic composition (surface layer composition) comprising, in a cosmetically acceptable medium, at least one second film-forming polymer and at least one colored polymer film fragment which exhibits two substantially flat faces, which has a thickness ranging from 40 to 200 &mgr;m and which has a larger dimension ranging from 0.1 to 4 mm, the fragment being insoluble in the medium of the composition, wherein the first composition does not comprise a polymer film fragment as present in the second composition.
Another embodiment of the invention is a made-up substrate comprising a make-up capable of being obtained according to the process as defined before and applied on said substrate.
The colored polymer film fragment can be obtained from radical polymers and in particular from vinyl polymers, such as acrylic polymers or polymers based on poly(vinyl acetate), styrene-acrylic, vinyl/versatate or vinyl/ethylene copolymers, or vinyl/versatate/acrylate or vinyl/ethylene/chloride terpolymers. Use is preferably made of styrene/acrylic copolymers.
The color of the film fragment is not critical and can be chosen from all possible colorings. Use may in particular be made of a mixture of film fragments with different colorings. The film fragment can also comprise a different color on each face, as disclosed in European Patent Application No. EP-A-679,698, the disclosure of which is hereby incorporated by reference.
The thickness of the film fragment can preferably range from approximately 70 &mgr;m to approximately 130 &mgr;m and better still from approximately 90 &mgr;m to approximately 110 &mgr;m.
The larger dimension of the film fragment, measured in the plane passing through one of the two flat faces of the film fragment, can preferably range from 0.1 mm to 2 mm and better still from 0.1 mm to 1 mm.
The fragmented film is preferably matt and therefore does not exhibit a sparkling or glossy effect. The fragmented film can advantageously have a gloss, measured using a Byk-Gardner glossmeter at a light beam angle of 60°, of less than or equal to 15, in particular from 3 to 15, and in particular ranging from 3 to 10.
The film fragment can be colored using pigments or dyes. Mention may be made, as pigment, of inorganic pigments, organic pigments, pearlescent agents or metal powders.
The film fragment can additionally comprise at least one filler, which makes it possible, in particular, to obtain a film having the desired physicochemical properties. Mention may be made, as filler, of calcium carbonate, magnesium carbonate, carbonate of lime, barium sulphate, talc or kaolin.
According to the invention, the colored film fragment can be present, in particular in the surface composition, in an amount preferably ranging from 0.5% to 30% by weight with respect to the total weight of this surface composition, more preferably from 3% to 20% by weight and better still from 5% to 15% by weight.
