Description

The present invention relates to cosmetic compositions and more

  particularly makeup compositions of the skin, lips or integuments. BACKGROUND It is known to incorporate in makeup compositions coloring agents whose color is sensitive to an external stimulus, these coloring agents being also called Xchromes coloring agents, X denoting the external factor. It may be, for example, photochromic, thermochromic, solvatochromic or tribochromic coloring agents.

  It is known to introduce diffusing pigments into the makeup compositions in order to produce colors by a phenomenon of absorption of light by specific chromophores. It is known to introduce in the makeup compositions diffusing pigments 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 colored background and sufficiently covering, 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 achieve a completely satisfactory result. Multilayer interference pigments, comprising a stack of layers whose refractive indices and thicknesses are suitably selected in order to generate a color by an interference phenomenon, make it possible to produce a greater intensity of color than the above diffusing pigments. 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 of the company LANCAM 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 deposit 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 the packaging more expensive. SUMMARY There is a need for a composition capable of providing coverage and producing a saturated color, so that in one go a makeup can be obtained that is both covering and colored. There is also a need to have a composition that has new effects. 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. According to one of its aspects, the subject of the invention is a cosmetic composition comprising, in a cosmetically acceptable medium, at least one multilayer interference pigment and at least one coloring agent sensitive to at least one external stimulus, the coverage of the composition being greater than or equal to 30, the multilayer interference pigment being in a content giving the composition a difference in color AE greater than or equal to 5 between the color in the mass and the color after application. The color after application is determined for the purposes of calculating ED after spreading the composition on a contrast map, as for measuring the coverage. The coloring agent sensitive to at least one external stimulus may be adapted to take, in a state, a color of dominant wavelength away from A ?. less than 30 nm of the dominant wavelength of the composition in the mass. Such a characteristic may for example make it possible to have the Xchrome coloring agent and the multilayer interference pigment substantially of the same color. Alternatively, the Xchrome coloring agent may be colorless in the bulk composition, which may be preferable when it is white in particular. The coloring agent sensitive to at least one external stimulus may be capable of taking, in a state, a dominant wavelength color distal from Al of less than 30 nm from the dominant wavelength of the composition after application on keratin materials. This can help strengthen the color of the composition after application. The coloring agent sensitive to at least one external stimulus may be colorless in a state, which corresponds for example to the presence of the stimulus or the absence of stimulus. This state can be found in the mass of the composition, before application to keratin materials or after application to keratin materials, alternatively. According to the combinations selected, the invention offers the possibility of creating multiple effects. The coloring agent sensitive to at least one external stimulus may be in solution in the medium or may be dispersed in particulate form in the medium, depending on its nature. The coloring agent sensitive to at least one external stimulus is, for example, a photochromic, thermochromic, solvatochromic, piezochromic, tribochromic or mechanoluminescent agent. The invention may comprise only one Xchrome staining agent or, alternatively, several Xchrome staining agents that are sensitive to stimuli of different natures. The composition may be anhydrous or aqueous. According to the compositions, the difference AE can be between 5 and 30 for example, especially greater than any integer value in this range. The coverage may be greater than 40, for example between 40 and 70, especially greater than any integer value in this range. In multilayer interference pigments, the production of color by the interference phenomenon competes 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 from the composition to the application, which confers a playful aspect to the use. The color variation upon application can be enhanced or varied by the presence of the external stimulus-sensitive coloring agent, which may also change color upon application, if desired. The invention also offers new possibilities for the marketing of cosmetic compositions, allowing the conditioning to be played on the color variation before and after application. The ratio ml / m 2 between the mass content mi of multilayer interference pigment and the content m2 of Xchrome coloring agent is, for example, from 0.1 to 1.5. The mass content of multilayer interference pigment can range from 7 to 20%, more preferably 8 to 15%, especially in the case of a non-pulverulent composition, for example liquid or cast. For a free or compacted powdery composition, the content of multilayer interference pigment ranges, for example, from 40 to 95%, more preferably from 50 to 80%. The color of the composition in the mass may be white when the composition is unexposed to the stimulus. The composition, by weight, may have a whiteness index greater than or equal to 40. The composition may not comprise any other coloring agent other than the multilayer interference pigment (s) and the external stimulus-sensitive coloring agent (s). . The multilayer interference pigment may comprise at least four layers, for example. The multilayer interference pigment may comprise a substrate made of a transparent material. The multilayer interference pigment may comprise a substrate of a more or less rough material, which may make it possible to impart more gloss to the composition. The multilayer interference pigment may comprise a substrate of a more or less rough material, which may make it possible to impart more or less gloss to the composition. The substrate is for example selected from natural, relatively rough mica, synthetic mica, alumina, silica or glass or metal for a smoother surface. The composition may comprise two multilayer interference pigments having layers consisting 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 composition may comprise two multilayer interference pigments having layers of the same materials, at least one layer of a pigment having a different thickness of a corresponding layer of the other pigment, so as to produce different colors. In examples, the composition comprises more than 30% by weight of total oil (s). In examples, the composition comprises more than 10% by weight of total wax (es). In examples, the composition comprises more than 10% by weight of the total charge (s). According to another of its aspects, the subject of the invention is also a non-pulverulent cosmetic composition, for example liquid (at 25 ° C.) or in the form of a stick, comprising, in a cosmetically acceptable medium: between 7 and 20% preferably 8 to 15% by weight, in total, of one or more multilayer interference pigments, between 0.1 and 10% by weight, in total, of one or more coloring agents that are sensitive to at least one stimulus outside. The invention further relates to a packaging assembly comprising: a composition as defined above; means for informing the user of the color of the composition after application. Another subject of the invention, according to another of its aspects, is a powdery composition, free or compacted, comprising, in a cosmetically acceptable medium: between 40 and 95%, better still 50 and 80%, even better 55 and 65% by weight, in total, of one or more multilayer interference pigments, - between 0.1 and 60%, better still 1 and 50% by weight, in total, of one or more coloring agents that are sensitive to at least one external stimulus. According to these latter two aspects, the composition may have one or more of the above-mentioned features, for example relating to the Xchrome coloring agent and its relationship to the multilayer interference pigment. Measurement of Coverage Liquid Compositions (at 25 ° C.) Liquid composition is understood to mean a composition whose 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 150 m thick 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 matte 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. These may be cast or powdered compositions 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 the deposit a sponge loaded with the composition and mounted on a disintegrating device that makes predefined movements to 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 BLENDERM. 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 space CIELab76 within the meaning of the International Commission on Illumination according to Recommendation 15: 2004. 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 The color in the mass is measured after filling a container having a depth large enough 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 = LL \ a 2 2 2 1/2 in the --- L * (* mass a * after application + (b * in the mass b after application + in the mass ùL * afterapplicatiae Measure whiteness index The whiteness index is calculated from the infinite-thickness color measurements and ASTM E313-05 Multilayer Interferential Pigment Multilayer interference pigment refers to 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 the multilayer interference pigments can be envisaged. produced by the multilayer interference pigment may be arbitrary, for example having a dominant wavelength between 580 and 650 nm or not. only multilayer interference pigment or multilayer interference pigments having different dominant wavelengths. The multi-layer interference pigment may comprise a substrate (also called a core or core) coated on at least one side 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 interferential pigment may comprise more than four different refractive index layers. 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 μm 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% for a non-pulverulent, liquid or cast composition, for example in a stick and from 40 to 95% for a powdery, free or compacted composition. . The coverage of the composition may be mainly due to the multilayer interference pigment content. 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. Examples of pearlescent agents include pearlescent pigments such as titanium mica coated with an iron oxide, mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with an organic dye in particular as well as pearlescent pigments based on bismuth oxychloride. It may also be mica particles on the surface of which are superimposed at least two successive layers of metal oxides and / or organic dyestuffs. The nacres may have a yellow, pink, red, bronze, orange, brown, gold and / or copper color or reflection. As an illustration of nacres that can be introduced as a multilayer interference pigment, mention may be made of gold-colored pearlescent agents marketed by the company Engelhard under the name Brillant gold 212G (Timica), Gold 222C (Cloisonne), Sparkle gold (Timica), Gold 4504 (Chromante) and Monarch Gold 233X (Cloisonne); bronze nacres sold especially by the company MERCK under the name Bronze Fine (17384) (Colorona) and Bronze (17353) (Colorona) and by Engelhard under the name Super Bronze (Cloisonne); orange nacres sold especially by Engelhard under the name Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by the company 5 Merck under the name Passion Orange (Colorona) and Matte Orange (17449) (Microna); brown-colored pearlescent agents marketed by Engelhard under the name Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); nacres with a copper sheen sold especially by Engelhard under the name Copper 340A (Timica); nacres with a red reflection 10, especially those marketed by MERCK under the name Sienna fine (17386) (Colorona); yellow-colored pearlescent agents marketed by ENGELHARD under the name Yellow (4502) (Chromalite); the red-colored pearlescent agents with a gold glint sold especially by ENGELHARD under the name Sunstone G012 (Gemtone); pink nacres sold especially by ENGELHARD under the name Tan opal G005 (Gemtone); the black nacres with gold reflection sold by the company Engelhard under the name Nu antique bronze 240 AB (Timica), the blue nacres sold especially by the company Merck under the name Matte Blue (17433) (Microna), the white nacres with reflection silver sold in particular by the company MERCK under the name Xirona Silver and the golden-green orange-colored mother-of-pearl marketed by Merck under the name Indian summer (Xirona) and their mixtures.

By way of example of such particles, mention may be made, for example, of particles comprising a synthetic mica substrate coated with titanium dioxide, or particles of coated glass of brown iron oxide, of titanium oxide, of tin oxide or one of their mixtures such as those sold under the trade name REFLECKS by ENGELHARD. 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 observation angle is varied with respect to the 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 spectrogonioreflectometer and GON 360 GONIOMETER reference, after the composition has been spread in the fluid state with a thickness of 300 m by means of FIG. an automatic spreader on a ERICHSEN brand contrast card and Typ 24/5 reference, the measurement being made on the black background of the card. The goniochromatic pigment may be chosen for example from interferential 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: MgF 2, CeF 3, 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 symmetry with respect to a central layer at the chemical nature of the stacked layers. Depending on the thickness and nature of the different layers, different effects are obtained. Examples of symmetrical multilayer interference structures are, for example, the following structures: Fe 2 O 3 / SiO 2 / Fe 2 O 3 / SiO 2 / Fe 2 O 3, a pigment having this structure being marketed under the name SICOPEARL by the company BASF; MoS2 / SiO2 / mica-oxide / SiO2 / MoS2; Fe 2 O 3 / SiO 2 / mica-oxide / SiO 2 / Fe 2 O 3; TiO2 / SiO2 / TiO2 and TiO2 / Al2O3 / TiO2, pigments having these structures being marketed under the name XIRONA by the company Merck (Darmstadt). The liquid crystal coloring agents include, for example, silicones or cellulose ethers onto which mesomorphic groups are grafted. Examples of goniochromatic liquid crystal particles that may be used are those sold by the company Chenix and those sold under the name HELICONE HC by the company Wacker. As the goniochromatic pigment, it is also possible to use certain nacres, pigments having effects on a synthetic substrate, in particular substrate such as alumina, silica, borosilicate, iron oxide, aluminum, or interfering flakes derived from a polyterephthalate film. The material may further comprise dispersed goniochromatic fibers. Such fibers may have a length of less than 80 m for example. Xchromes coloring agents These may be photochromic coloring agents. Photochromic Coloring Agents In general, a photochromic coloring agent is a coloring agent having the property of changing color when illuminated or not by ultraviolet light and restoring its original color when not present. more light or not by a light or to move from an uncolored state to a colored state and vice versa. In other words, such an agent has different hues depending on whether it is illuminated by light containing a certain amount of UV radiation. The photochromic coloring agent can take in the presence of low light a substantially undyed state. In the presence of strong illumination, the photochromic coloring agent may take on a colored state, for example a dark hue or a color having substantially the same dominant wavelength as the multilayer interference pigment, which may make it possible to appear less multilayer interference pigment multilayer than in the presence of low light. This effect may surprise the observer and make the makeup particularly attractive. The photochromic coloring agent may have a gap AE at least equal to 5. AE denotes the color difference observed at the level of the photochromic material between its excited state, that is to say in the presence of UV irradiation. and its non-excited state, i.e., in the absence of UV irradiation. It will be useful to refer to the examples of photochromic agents described in US 2004/0228818, the contents of which are incorporated by reference, in particular those having an AE greater than 5, according to the test presented in this document.

Examples of photochromic agents are diarylethene, of the formula and its derivatives, dihydroazulene / vinylhepta fulvene, of formula and its derivatives, spyronaphthoxazine, of formula R 1 N N and its derivatives. The photochromic agent may be an organic or inorganic compound. When the photochromic agent is an organic compound, the color change can generally be faster and more intense. By way of examples of photochromic agents, mention may be made of Photosol from PPG, which reversibly changes color when activated by UV radiation with a wavelength of between 300 and 360 nm, the Reversacol of the Company J. ROBINSON and the Photogenica of CATALYST & CHEMICALS. Thermochromic agents A thermochromic agent is a pigment or dye that can change color depending on the temperature. The thermochromic agent, for example, has a color which is lost when the temperature exceeds a certain value, for example about 15 ° C or about 30 ° C, depending on the nature of the thermochromic agent. The thermochromic agent may comprise capsules of a polymer containing a solvent, this solvent allowing, depending on whether it is melted or not, compounds to come into contact and to modify the absorption properties of the light radiation. The color change may be reversible. It is possible, for example, to use the thermochromic agent sold under the reference Kromafast Yellow5GX 02 by the company KROMACHEM LTD or Chromazone powder or dispersion, Thermobatch or Thermostar, from CHROMAZONE. Piezochromic and tribochromic agents A piezochromic agent is likely to change color in the presence of a mechanical force. Examples of piezochromic agents include diphenylflavylene. A tribochromic agent is likely to change color in the presence of a mechanical force, more sustainably than in the case of piezochromic agents.
