Description

The present invention relates to cosmetic compositions, and more

  especially those intended for the makeup of keratin materials. BACKGROUND It is known to introduce diffusing pigments into makeup compositions to produce colors by a phenomenon of absorption of light by specific chromophores. To these diffusing pigments, which are necessary to benefit from a continuous and sufficiently covering colored background, may be added effect particles (s) to create, for example, points of gloss or impart a pearlescent appearance. However, the intensity of the color produced by these compositions may be insufficient to lead to a completely satisfactory result. Multilayer interference pigments, comprising a stack of layers whose refractive indices and thicknesses are suitably selected to generate a color by an interference phenomenon, make it possible to produce a greater color intensity than the diffusing pigments above. . To the knowledge of the inventor, in commercially available compositions, these multilayer interference pigments are employed at a mass concentration of not more than 5%. It is moreover known by CHRYSALIDE brand eyeshadows from LANCAME to confer both coverage and color intensity by means of a make-up involving a first act of depositing on the keratin materials a base layer of black color containing a diffusing pigment providing coverage and then depositing by a second gesture on this base layer a composition providing color through a multilayer interference pigment. Without the base layer, the covering layer is almost invisible because it is not covering and without color. The use of two successive applications complicates makeup and makes packaging more expensive. 2910272 2 Abstract There is a need to benefit from compositions capable of providing coverage and producing a saturated color, in order to be able to obtain in a single gesture a makeup that is both covering and colored. Furthermore, it is desirable to benefit from cosmetic compositions intended for the makeup of keratin materials which present new effects that are likely to attract consumers, without these new effects occurring to the detriment of the quality of the makeup obtained. The invention aims in particular to meet all or part of the needs identified above. The subject of the present invention is, according to one of its aspects, a range of cosmetic compositions comprising at least two compositions each comprising a cosmetically acceptable medium and at least one multilayer interference pigment, the compositions being each of coverage greater than or equal to 30. the respective multilayer interference pigments of the different compositions being chosen so that the colors of the compositions in the mass, taken in pairs, differ from an AE gap before application of less than or equal to 2 and that the compositions after application have, taken two by two, a color difference AE after application greater than or equal to 2, better 5. The color after application is determined for the purposes of calculating AE after spreading the composition on a contrast map, as for the measurement of coverage. By range, it is necessary to understand a plurality of compositions proposed to consumers, for example under the same brand and in the same packaging. The range according to the invention can be supplemented in the offer to consumers by a wider range comprising compositions not corresponding to the invention, for example proposed under the same brand and in the same packaging as the compositions according to the invention. invention. The compositions of the range can be all anhydrous or all aqueous. The coverage may be greater than 30, for example between 40 and 70, for example greater than any integer value in this range. Each composition may have a color difference between the color in the mass and the color after application greater than or equal to 5, for example greater than one of the integer values in the range 5 to 30. With the pigments In the case of multilayer interference, the production of color by the interference phenomenon is in competition with the production of color by the phenomenon of absorption by the surface layer of the pigment. Thus, when the pigment concentration increases sufficiently, the color produced by the interference phenomenon decreases in favor of that produced by absorption.

  The invention, by exploiting this property, makes it possible to observe a color variation of each composition of the range at the application, which confers a playful aspect to the use. This playfulness is reinforced in that all the compositions in the range have substantially the same color in the mass. The invention also offers new possibilities in the marketing of cosmetic compositions, allowing to play at the packaging level on this color variation before and after application. The color of each composition of the range, in the mass, can be white. Each composition in the range, in bulk, may have a whiteness index greater than or equal to 40. Each composition in the range may not comprise any other coloring agent other than the multilayer interference pigment or pigments. At least one multilayer interference pigment of the compositions of the range may comprise at least four layers, for example. At least one multilayer interference pigment of at least one composition in the range may comprise a substrate of a transparent material. A composition of the range may comprise two multilayer interference pigments having layers made of the same materials, at least one layer of a pigment having a thickness different from a corresponding layer of the other pigment, so as to produce different colors. . The compositions of the range may each comprise at least one multilayer interference pigment having a substrate comprising an oxide of iron or aluminum. The multilayer interference pigments of all compositions in the range may have the same dimensions, to within 20%. The multilayer interference pigments of all the compositions of the range may have a substrate of the same kind and / or a surface layer of the same kind. This can facilitate the same color in the mass. All compositions in the range may have the same compounds except for the respective multilayer interference pigments. At least two compositions may differ from each other only by the thickness of at least one of the interferential layers of their respective interferential pigments. The number of compositions in the range may be between 2 and 8, for example.

  The range may comprise at least three compositions having multilayer interference pigments, the total mass contents Xk of multilayer interference pigment (s) of the three compositions in the range being respectively less than or equal to 8, strictly greater than 14 and between 12 and 14. The three compositions may comprise the same multilayer interference pigment. The range may comprise at least two or even three or four compositions with different respective multilayer interference pigments at the same mass content. All compositions in the range can be packaged in identical containers. Each composition may be packaged with means indicating the color of the composition after application. It may be for example an ink or varnish printing, a thin layer of composition or a molding or overmolding of a material incorporating the multilayer interference or pigments. The invention also relates to a range ... claim 28. 2910272 5 Measurement of coverage Liquid compositions (at 25 C) By liquid composition is meant a composition of which only the viscosity can be measured. A liquid composition can flow under the effect of its own weight. The coverage of the compositions is measured at a finite thickness of 50 m for the liquid compositions to be applied to the lips, in particular liquid lipsticks, liquid lip glosses and liquid lip balms, and at a thickness of 150 μm for varnishes. nails, eye shadows, liquid foundations, mascaras and other liquid make-up products not intended to be applied to the lips. The composition is spread on matt black and matt white contrast cards, for example LENETA Form WP1 for the matte black card and Leneta lA for the matt white card. The application can be performed with an automatic spreader. The measurements are carried out on the compositions thus spread. Solid Compositions (at 25 ° C.) Solid compositions are those whose viscosity can not be measured. It may be compositions cast in a stick or powder form, in the form of free or compact powders. A) For powdery solid compositions, free or compacted, the composition is applied using the same contrast cards as above, covered with a transparent tape, slightly rough, for example brand BLENDERM 3M company and 15025, glued by the adhesive side on the contrast cards. The composition is deposited on the adhesive tape so as to obtain a homogeneous deposition of 0.5 mg / cm 2 0.02 mg / cm 2. It is possible to use for depositing a sponge loaded with the composition and mounted on a disintegrating device that makes predefined movements with the sponge. The sponge is for example a disposable sponge type LANCAME Photogenic, used on the pink side. b) The stick compositions are melted, for example at 90 ° C., and then spread in the liquid state on matt black and matt white contrast cards, for example with the same references as above, not covered with BLENDERMe. The spreading bar is maintained at the same temperature as the composition, so as to avoid thermal shock. The stick compositions for application to the lips are thus deposited once melted with a thickness of 50 m. The other compositions are spread with a thickness of 150 m. Measurements and Calculations Reflectance spectra are acquired using a MINOLTA 3700-d spectrocolorimeter (diffuse measurement geometry and observation D65 / 10, specular component excluded mode, small aperture (CREISS)) on the black and white backgrounds , the contrast cards being optionally covered with BLENDERM as indicated above. The spectra are expressed in colorimetric coordinates in the CIELab76 space within the meaning of the International Commission on Illumination according to Recommendation 15: 2004. 2910272 0 7 The contrast ratio, or coverage, is calculated by averaging Y on a black background, divided by the average value of Y on a white background, multiplied by 100. Measuring the color of the composition in the mass 5 The color in the mass is measured after filling a container having a sufficiently large depth to be able to consider an infinite product thickness in view of the measurement, for example a depth of 3 mm or more. The coordinates L *, a * and b * are measured with a spectrocolorimeter, for example a MINOLTA CM-2002 mark (D65 / 10, specular component mode excluded). Color measurement after application The color is measured on the dark background of the contrast card, the composition being spread as for the coverage measurement as detailed above. The difference AE is calculated as follows:] AE = (a * in the mass -a * after apyGecrtior) '+ (b * dau.c mass b * np)' + (L * in the silly L * after applkatirn The whiteness index is calculated from the infinite-thickness color measurements and ASTM E313-05. Multilayer interference pigment The term "multilayer interference pigment" denotes a pigment capable of producing a color by a phenomenon of interference between the light rays reflected by a plurality of superimposed layers of different refractive indices, in particular a succession of layers of high and low refractive indices. All multilayer interference pigments can be envisaged. The color produced by the multilayer interference pigment may be any, for example being of dominant wavelength between 580 and 650 nm or not. The composition may comprise a single multilayer interference pigment or several multilayer interference pigments having different dominant wavelengths. The multilayer interference pigment may comprise a substrate (also called a core or core) coated on at least one face with one or more layers of selected materials and thicknesses such that a color is produced by interference. Layers of the interference pigment may or may not surround the substrate, which may have a flattened shape or not. The substrate may comprise natural mica, synthetic mica, glass, alumina, silica, or any metal, alloy or metal oxide. The nature of the substrate may be chosen according to the desired gloss. For example, for a very bright rendering, a substrate of glass or metal may be preferred. The interference pigment may comprise more than four layers of different refractive indices. The particle size of the multilayer interference pigment, given by the average particle size at half of the population, also called D50, ranges, for example, from 1 m to 2000 μm, better still from 5 μm to 2000 μm. The proportion of multilayer interference pigment is, for example, greater than 7% and ranges, for example, from 7 to 20%, more preferably 8 to 15%, for a non-pulverulent, liquid or cast composition, for example as a stick and 40 to 95% more preferably 40 to 80%, for a powdery composition, free or compacted. The coverage of the composition may be due essentially to the content of multilayer interference pigment. Alternatively, at least one diffusing pigment and / or fillers can provide coverage. Nacres are examples of multilayer interference pigments that may be suitable. Nacres By nacre, it is necessary to include colored particles of any shape, iridescent or not, in particular produced by certain shellfish in their shell or else synthesized and which exhibit a color effect by optical interference.

The multilayer interference pigment may be a goniochromatic pigment. Goniochromatic Pigment For the purposes of the present invention, the term "goniochromatic pigment" denotes a pigment which makes it possible, when the composition is spread on a support, to obtain a color path in the plane a * b * of the CIE 1976 color space. corresponds to a variation Dh of the hue angle h of at least 20 when the angle of observation is varied from normal between 0 and 80, for an angle of incidence of the light of 45. The color path can be measured for example by means of an INSTRUMENT SYSTEMS brand spectrogoniorflectometer and reference GON 360 GONIOMETER, after the composition has been spread in the fluid state with a thickness of 300 m by means of a automatic spreader on an ERICHSEN brand contrast card and Typ 24/5, the measurement being made on the black background of the card. The goniochromatic pigment may be selected from, for example, interfering multilayer structures and liquid crystal coloring agents. In the case of a multilayer structure, this may comprise for example at least two layers, each layer being made for example from at least one material selected from the group consisting of the following materials: MgF2, CeF3, ZnS , ZnSe, Si, SiO 2, Ge, Te, Fe 2 O 3, Pt, Va, Al 2 O 3, MgO, Y 2 O 3, S 2 O 3, SiO, HfO 2, ZrO 2, CeO 2, Nb 2 O 5, Ta 2 O 5, TiO 2, Ag, Al, Au, Cu, Rb, Ti, Ta, W, Zn, MoS2, cryolite, alloys, polymers and their combinations. The multilayer structure may or may not have, with respect to a central layer, a symmetry at the chemical nature of the stacked layers.
