Cosmetic composition for application to the skin, lips and/or nails.

0001The present invention relates to cosmetic compositions intended to be applied to the skin, including the mucous membranes, in particular the lips, and the integuments, in particular the nails, eyelashes, eyebrows and hair.

0002Organic coloring matters are commonly used to bring color to cosmetic compositions. However, conventional organic coloring materials do not make it possible to obtain compositions having a satisfactory covering power. In addition, the colors provided by these organic coloring materials vary greatly between the dry state and the state in dispersion in a cosmetic solvent.

0003There is a need to have cosmetic compositions having a satisfactory saturation C * and a sufficiently high covering power.

0004There is still a need for pigments having a slight change in color depending on the surrounding environment.

0005The present invention aims to meet all or part of the aforementioned needs.

0006It achieves this by virtue of a composition having a covering power advantageously between approximately 25 and approximately 100, for example between approximately 25 and approximately 90, or even between approximately 30 and approximately 100, for example between 30 and approximately 90, this composition being intended to be applied to the skin, the lips and / or the integuments and comprising particles of at least one composite pigment, these particles comprising:<ul id="ul0001" list-style="dash" compact="compact"><li>an inorganic nucleus,</li><li>at least one at least partial coating of at least one organic coloring matter in an amount sufficient for the saturation C * of the composition to be preferably between approximately 25 and approximately 100, or even between approximately 30 and approximately 100.</li></ul>

0007Thanks to the invention, it is possible to obtain compositions which are both saturated and covering.

0008The content of composite pigment in the composition may be between approximately 0.1% and approximately 30%, or even between approximately 0.1% and approximately 20%, for example between approximately 0.1% and approximately 15%, or even between approximately 0.3% and 10% approximately, for example between approximately 1% and approximately 5% by weight, relative to the total weight of the composition.

0009In particular, it is possible to choose a relatively high composite pigment content in order to obtain the desired covering power and in particular a relatively high covering power.

0010A suitable shade can be obtained in various ways, for example by mixing the composite pigments according to the invention, these pigments having different colors and / or by the presence of several organic coloring matters in the coating of the cores of the pigment (s). composites, these organic coloring matters being, for example, mixed or present in respective layers of the coating.

0011By "an at least partial coating" is meant within the meaning of the present invention, a coating of all or part of the inorganic nucleus.

0012The composition according to the invention can comprise a physiologically acceptable medium.

0013By "physiologically acceptable medium" is meant a non-toxic medium capable of being applied to the skin, the lips or the integuments of human beings, in particular a cosmetic medium. The physiologically acceptable medium will be adapted to the nature of the support on which the composition is to be applied, as well as to the form in which the composition is intended to be packaged, in particular solid or fluid at room temperature and under atmospheric pressure.

0014By "cosmetic composition" is meant a composition as defined in Council Directive 93/35 / EEC of June 14, 1993.

<i><b>MEASUREMENT OF SATURATION C *</b></i>

0015In the case of a liquid or pasty composition, a sample of the composition to be studied is introduced into a metal dish about 1 cm deep. A 1 mm thick quartz slide is applied to the composition, taking care to avoid air bubbles before making the measurement.

0016In the case of a powder composition, the powder sample is compacted at a pressure of 10 MPa in a metal cup about 1 cm deep. A 1 mm thick quartz slide is applied to the composition before making the measurement.

0017In the case of a stick, the composition is poured into a flat bottom quartz mold about 2 cm deep.

0018The trichromatic coordinates L *, a *, b * of the composition in the CIE space L * a * b * are measured using a CM-508d spectrocolorimeter from MINOLTA, under illuminant D65, with a specular component included and a d / 8 lighting system.

0019The saturation C * of the composition is calculated using the formula C * = [(a *)²+ (b *)²]^1/2.

<i><b>MEASUREMENT OF COVERING POWER</b></i>

0020In the case of a stick, the formulation is previously kneaded so as to obtain a viscous paste.

0021In the case of a powder, 50 parts by weight of the powder are mixed with 50 parts by weight of dimethicone (DC 200 Fluid 5CST from DOW CORNING) so as to obtain a viscous paste.

0022The formulation is then spread with a thickness of 30 μm on an Erichsen contrast card, type 24/5, having a black background and a white background, and the trichromatic coordinates (X, Y, Z) are measured using '' a CR-300 colorimeter.

0023Similar spreads are made on two other contrast cards and three measurements are made on each card. The average corresponding to these nine measurements is then calculated.

0024The covering power is equal to 100 x Yn / Yb where Yn is the average value of Y on a black background and Yb is the average value of Y on a white background. A covering power of 100 corresponds to a completely opaque formulation.

0078In an example of implementation, one begins by mixing the particles intended to constitute the inorganic nucleus with the binder.

0079In order for the binder to adhere uniformly to the surface of the inorganic core, it is preferable to pass these particles beforehand through a grinder, so as to deagglomerate them.

0080The mixing and stirring conditions are chosen so that the core is uniformly covered with binder. These conditions can be controlled so that the linear load is between 19.6 and 19,160 N / cm, in particular between 98 and 14,170 N / cm and better still between 147 and 980 N / cm; the treatment time is in particular between 5 min and 24 hours and better still from 10 min to 20 hours; the rotation speed can be between 2 and 1000 rpm, in particular between 5 and 1000 rpm and better still between 10 and 800 rpm.

0081After the binder has covered the inorganic core, the organic coloring matter is added and mixed with agitation to adhere to the binder layer.

0082The addition methods can be, for example, addition by large quantity, continuously, or by small quantity.

0083Mixing and stirring, whether of inorganic nuclei with the binder or of organic coloring matter with the inorganic nuclei covered with binder, can be carried out using an apparatus capable of applying a spatial cutting and / or compressive force to the mixture powders. Such devices are, for example, wheel, blade and similar mixers. Wheeled mixers are particularly suitable. A list of suitable devices is given in application EP 1 184 426 A2.

0084Another method of manufacturing a composite pigment is described in patent JP 3286463, which discloses a method of precipitation in solution.

0085The organic coloring matter is dissolved in ethanol, the inorganic nuclei are then dispersed in this ethanolic solution.

0086Then, an alkaline aqueous solution of sodium or potassium carbonate is slowly added to these mixtures, then last, slowly, an ethanolic solution of calcium chloride, all with stirring.

0146The compositions of Example 3 and Comparative Example 3 contain the same ingredients in the same proportions, except for the pigments.

0147The covering power and the saturation C * of the compositions of Example 3 and Comparative Example 3 were measured.<tables id="tabl0009" num="0009"><img file="EP1586296A1_D0008.tif" /></tables>

0148The covering power and the saturation C * of the composition of Example 3 are higher than those of the composition of Comparative Example 3.

0149Of course, the invention is not limited to the examples which have just been given.

0150The intervals given must be included, limits included, unless otherwise specified.

0151Throughout the description, including the claims, the expression "comprising a" should be understood as being synonymous with "comprising at least one", unless otherwise specified.
