ABSTRACT:
The present invention relates to a process for making up keratin substances, comprising the application to the keratin substances of a first coat of a film-forming composition and a second coat of solid particles. The invention also relates to a make-up kit for carrying out the process. The process according to the invention can be applied to the skin both of the face and of the body, to the lips and to superficial body growths such as the nails, the eyelashes, the eyebrows or the hair; this process is particularly suitable for making up the nails.
The film-forming composition can be a nail varnish, a face powder, an eyeshadow, a foundation, a make-up product for the lips or a make-up product for the body.
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. Such varnishes are described, for example, in documents U.S. Pat. No. 4,158,053 and FR-A-2 578 741.
After applying one or more coats of the composition to the nail and after drying, these nail varnishes generally lead to the formation of a smooth, continuous and homogeneous, glossy or matt film. Certain films also have good cosmetic properties such as good staying power and in particular good adhesion to the nail, and good resistance to water, to rubbing and to impacts.
With the change in fashion, more demanding consumers are looking for new make-up products which give original or specific make-up effects. There is thus a need to provide a make-up product whose application to a support such as the skin or the superficial body growths of human beings gives a make-up effect which is different from that of the continuous and homogeneous films currently obtained with the products available on the market.
The aim of the present invention is thus to provide a make-up composition for obtaining a relief make-up on the skin and on superficial body growths, while at the same time having good staying power over time.
The Applicant has found that a novel type of make-up for the skin and/or superficial body growths can be obtained using a specific process for applying a film-forming composition and solid particles. This process makes it possible to distribute and maintain at the surface particles more or less uniformly at the surface: an original relief make-up effect is thus obtained, giving volume and body to the keratin substances, for example the nails. In addition, the make-up has good adhesion to the made-up support and good staying power, in particular with respect to rubbing and impacts. Furthermore, the particles give the impression of the presence of bubbles at the surface of the make-up.
More specifically, a subject of the invention is a process for making up keratin substances, which consists in applying to the keratin substances a first coat of a first film-forming composition comprising a cosmetically acceptable medium and at least one first film-forming polymer, followed by applying to at least a part of the first coat, and before the first coat has dried, a second coat consisting essentially of solid particles that are insoluble in the cosmetically acceptable medium of the first composition and having a density ranging from 800 kg/m

, the solid particles having a substantially spherical or ovoid shape.
A subject of the invention is also a make-up kit comprising a first composition comprising at least one first film-forming polymer in a cosmetically acceptable medium, and solid particles having a substantially spherical or ovoid shape and having a density ranging from 800 kg/m

.
According to the invention, the second coat is applied at least to a part of the first coat, or even to all of the first coat, before the first coat has dried. It can be applied either to one of the ends of the first coat or to the middle, or alternatively in a discontinuous manner, in particular in the form of symmetrical or dissymmetrical geometric patterns (for example in the form of spots, squares, circles or stars), distributed randomly or in an ordered manner, along precise or vague contours.
In the process according to the invention, the second coat is obtained by direct application of the solid particles without them being mixed with a liquid medium, to allow good distribution on the surface of the first coat.
According to a first embodiment of the process of the invention, the second coat can be applied by sprinkling the solid particles onto the first coat before drying. The particles then come into contact with the first coat and become distributed more or less uniformly over the entire surface of the first coat. The excess of particles not in contact with the first coat do not become bound and are removed when the support thus made up is shaken or when the excess of particles is removed with a fine or coarse brush or with a puff of air. The sprinkling can advantageously be carried out through a screen or a stencil.
According to a second embodiment of the process according to the invention, the surface of the first coat applied to the keratin substances is placed in contact, before drying, directly with the solid particles stored, for example, in a container. In the case of a nail varnish, the fingers can be dipped directly into a finger dish.
The process according to the invention thus makes it possible to deposit and bind a quite homogeneous coat of solid particles which is of uniform thickness, thus giving an original relief make-up effect. Furthermore, the particles of substantially spherical or ovoid shape give the make-up a soft feel.
This two-layer architecture can be adapted to any make-up product for the skin not only for the face but also for the scalp and the body, for mucous membranes such as the lips, and for superficial body growths such as the nails. This architecture can also be applied to make-up accessories such as false nails, false eyelashes, wigs or to adhesive patches or disks on the skin or the lips (such as beauty spots).
It is possible to apply to the second coat of solid particles a third coat of a second film-forming composition comprising, in a cosmetically acceptable medium, a second film-forming polymer. This third coat makes it possible in particular to ensure very good staying power of the second coat on the first coat; it also makes it possible to provide colour shades, in particular when the colour of the third coat is different from the colour of the first coat and/or from the colour of the particles in the second coat.
The invention also relates to a made-up support whose make-up effect can be obtained by the process according to the invention.
Another subject of the invention is the use of the first composition and of the solid particles as defined above to obtain a make-up effect with surface relief, which has good staying power.
A subject of the invention is also the use of solid particles as defined above to obtain a make-up effect with surface relief, which has good staying power.
The Inventors have found, surprisingly, that the application of the solid particles in accordance with the process according to the invention makes it possible to obtain a make-up effect with uniform surface relief, which has good adhesion to the made-up support and good staying power in particular with respect to rubbing and to impacts. On the other hand, by adding the solid particles to a film-forming composition as defined above, the particles have a tendency to sediment out during storage of the composition, and it is difficult to obtain a uniform distribution of these particles in the film-forming composition. As a result, the application of this mixture, for example using a fine brush, is made difficult on account of the heterogeneity of the mixture and this application does not give a uniform distribution of the particles deposited onto the support to be treated. Thus, the process according to the invention makes it possible to obtain a make-up effect with homogeneous relief comprising a uniform distribution of the solid particles. This process allows the first
