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 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 lead to 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, with the exception of powders, these multilayer interference pigments are employed at a mass concentration not exceeding 5%.

  It is also known by CHRYSALIDE eyeshadow brand LANCAME to confer both coverage and color intensity using a makeup involving a first act of depositing on the keratin materials a base layer of color black 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. 2910273 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. According to one of its aspects, the subject of the present invention is 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 25. more preferably 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 by a difference L \ E before application less than or equal to 3 and that the After application compositions, taken in pairs, a color difference AEafter application greater than or equal to 5. The color after application is determined for the purposes of calculating AE 20 after spreading the composition on a contrast map, as for the measure of coverage. By range, it is necessary to understand a plurality of compositions proposed to consumers, for example under the same brand and in packaging. The range according to the invention can be supplemented in the offer to consumers by a wider range comprising compositions which do not correspond 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. AEavantappiication can be less than or equal to 2, AEaapplication can be greater than or equal to 5, better 6. 2910273 3 The coverage can be greater than 25, for example between 30 and 70, for example greater than any integer value in this interval , for example greater than or equal to 40. 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 multilayer interference pigments, 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 application, which gives 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 in the range, in the mass, may be white. By white it is necessary to understand achromatic in the sense of the CIE. 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 dyeing agent 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 made of a transparent material. A composition of the range may comprise two multilayer interference pigments having layers made of the same materials, but 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 the 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. All the compositions of the range may have the same compounds apart from the respective multilayer interference pigments. This can facilitate the same color in the mass. 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 of the multilayer interference pigment (s) of the three compositions in the range being respectively less than or equal to 20, strictly greater than 14 and between 12 and 14. The compositions of the range may comprise the same multilayer interference pigment. The range may comprise at least two or even three or four compositions having different respective multilayer interference pigments at the same specific gravity. All compositions in the range can be packaged in identical containers. The subject of the invention is also a range of non-pulverulent cosmetic compositions, in particular liquid or stick compositions, each comprising, in a cosmetically acceptable medium, one or more multilayer interference pigments, with, for at least one composition, a total mass content of pigment (s). ) interferential (s) 2910273 5 multilayer internal or equal to 9% and for a composition a content greater than or equal to 1 1%. Each composition may be packaged with means indicating the color of the composition after application to keratin materials (lips, skin, nails, eyelashes, eyebrows, hair). 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. Measurement of Coverage Liquid Compositions (at 25 ° C) Liquid composition means 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, the liquid compositions being, for example, compositions for application to the lips, in particular liquid lipsticks, liquid lip glosses and liquid lip balms, nail polishes, 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 coverage measurements are performed on the compositions thus spread. Solid Compositions (at 25 ° C.) The 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, free or compacted solid compositions, the composition is applied using the same contrast cards as above, covered with a transparent, slightly rough, eg 2910273 6 BLENDERM brand adhesive tape from the company. 3M 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 spraying 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., then spread in the liquid state with a thickness of 50 μm on matt white and matt white contrast cards, for example with the same references as above. above, not covered with BLENDERM. The spreading bar is maintained at the same temperature as the composition, so as to avoid thermal shock. 15 Measurements and Calculations Reflectance spectra are acquired using a MINOLTA 3700-d spectrocolorimeter (diffuse measurement geometry / 8 and observation D65 / 10, specular component excluded mode, small aperture (CREISS)) on black backgrounds and white, 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. 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). 2910273 7 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 5 but at a thickness of 1501.tm instead 50 m for liquid and non-pulverulent compositions, especially in stick. . The difference AE is calculated as follows: L (Q * in the mass after *) Z + (b'k in the mass' kaprapplicatia) 2 + (L * in the mass _L * afterapplicatia / I) 2 Jll / z 10 Whiteness Index Measurement The Whiteness Index is calculated from the infinite-thickness color measurements and ASTM E313-05. Multilayer interference pigment The expression "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 having a 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 multi-layer interference pigment may comprise a substrate (also called a core or core) covered on at least one face with one or more layers of materials and thicknesses chosen so that a color is produced by interference. Interferential pigment layers 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, is, 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%, more preferably 8 to 15%, for a non-pulverulent, liquid or cast composition, for example in a stick and from 40 to 95%, better 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 understand colored particles of any shape, iridescent or not, in particular produced by certain molluscs in their shell or else synthesized and which exhibit a color effect by optical interference. Examples of pearlescent agents that may be mentioned are pearlescent pigments such as iron oxide-coated titanium mica, bismuth oxychloride-coated mica, titanium mica coated with chromium oxide, titanium mica coated with a 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. By way of illustration of pearlescent agents which may be introduced as multilayer interference pigment, mention may be made of gold-colored pearlescent agents marketed by ENGELHARD under the name of Brillant gold 212G 2910273 9 (Timica), Gold 222C (Cloisonne), Sparkle gold (Timica), Gold 4504 (Chromalite) and Monarch gold 233X (Cloisonne); bronze nacres sold especially by the company Merck under the names Bronze Fine (17384) (Colorona) and Bronze (17353) (Colorona) and by Engelhard under the name Super Bronze 5 (Cloisonne); orange nacres sold especially by the company Engelhard under the name Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by the company Merck under the name Passion Orange (Colorona) and Matte Orange (17449) (Microna); the nacres of brown hue sold especially by the company Engelhard under the name Nu-antique copper 340XB (Cloisonne) and Brown 10 CL4509 (Chromalite); nacres with a copper sheen sold especially by Engelhard under the name Copper 340A (Timica); the nacres with a red glint sold especially by MERCK under the name Sienna fine (17386) (Colorona); yellow-colored pearlescent agents marketed by ENGELHARD under the name Yellow (4502) (Chromalite); nacres of red hue with gold reflection sold especially by ENGELHARD under the name Sunstone G012 (Gemtone); pink nacres sold especially by Engelhard under the name Tan opal G005 (Gemtone); black nacres with a gold glint sold especially by ENGELHARD under the name Nu antique bronze 240 AB (Timica), blue pearls especially sold by the company MERCK under the name Matte blue (17433) (Microna), white nacres to silvery reflection sold especially by the company Merck under the name Xirona Silver and the golden-green orange-colored mother-of-pearl sold by Merck under the name Indian Summer (Xirona) and their mixtures.

The multilayer interference pigment may be further selected from interferential reflective particles. Interferential Reflective Particles These particles may be chosen from particles with a synthetic substrate at least partially coated with at least one layer of at least one metal oxide, chosen for example from titanium oxides, in particular TiO 2, in particular Fe 2 O 3, tin, chromium, barium sulfate and the following materials: MgF 2, CrF 3, ZnS, ZnSe, SiO 2, Al 2 O 3, MgO, Y 2 O 3, SeO 3, SiO, HfO 2, ZrO 2, CeO 2, Nb 2 O 5, Ta 2 O 5, MoS 2 and mixtures thereof or alloys. By way of example of such particles, there may be mentioned, for example, particles comprising a titanium dioxide-coated synthetic mica substrate, or coated glass particles of brown iron oxide, titanium oxide, titanium dioxide or tin oxide or a mixture thereof such as those sold under the trade name REFLECKS by ENGELHARD. The multilayer interference pigment may further be a goniochromatic pigment. Goniochromatic Pigment For the purpose of the present invention, the term "goniochromatic pigment" denotes a pigment which makes it possible to obtain, when the composition is spread on a support, 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 brand spectrogoniorflectometer and reference GON 5 360 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. Depending on the thickness and the nature of the different layers, different effects are obtained. Examples of symmetrical interferential multilayer 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; TiO 2 / SiO 2 / TiO 2 and TiO 2 / Al 2 O 3 / TiO 2, pigments having these structures being sold under the name XIRONA by the company Merck (Darmstadt).

As an example of fillers, mention may be made, inter alia, of talc, mica, silica, kaolin, and polyamide powders (Nylon or Orgasol from Atochem). 2910273 20 The content of charges will be chosen so as not to unduly hinder the result

  research. Active ingredients and other compounds The cosmetic composition may also contain one or more cosmetic, dermatological, hygienic or pharmaceutical active ingredients. As cosmetic, dermatological, hygienic or pharmaceutical active agents that can be used in the compositions of the invention, mention may be made of moisturizers (polyol as glycerol), vitamins (C, A, E, F, B, or PP), essential fatty acids, essential oils, ceramides, sphingolipids, liposoluble sunscreens or in the form of nano-particles, 10 specific skin treatment active agents (protective agents, anti-bacterial agents, anti-wrinkles, etc.). These active agents can be used for example at concentrations of 0.001 to 15% relative to the total weight of the composition. The cosmetic composition may also contain ingredients commonly used in cosmetics, such as, for example, thickeners, surfactants, trace elements, moisturizers, softeners, sequestering agents, perfumes, alkalizing or acidifying agents, preservatives, antioxidants, UV filters, or mixtures thereof. The cosmetic composition may furthermore comprise, depending on the type of application envisaged, the constituents conventionally used in the considered domains, which are present in an amount appropriate to the desired dosage form. Dosage Forms Each cosmetic composition in the range may be in any galenical form normally used for topical application and especially in anhydrous or non-anhydrous form, in solid, semi-solid form, in an oily or aqueous solution, in a oily or aqueous gel, an oil-in-water or water-in-oil emulsion, a multiple emulsion, an oil dispersion in water through vesicles located at the oil / water interface water or spray. Preferably, all compositions in the range are of the same dosage form. By anhydrous composition is meant a composition having less than 5% by weight of water, better less than 3%, or even less than 1%. An anhydrous composition may not contain intentionally added water during the preparation of the composition. Each of the composition range may in particular be in the form of a stick.

The cosmetic compositions of the range may each constitute, among other makeup products, a lipstick, a liquid gloss, a lipstick paste, a blush, a foundation, an eye contour product, an eyeliner, a mascara, a nail polish, an eye shadow, a make-up base, a body make-up product or a hair.

All compositions in the range may be for the make-up of skin, lips, nails, eyelashes or eyebrows or hair. All the compositions of the range can be obtained according to the preparation methods conventionally used in cosmetics.

Packaging and methods of application Each composition of the range may be packaged in any receptacle or on any support provided for this purpose. Each composition may be applied using an applicator, flocked or not, for example a foam, a tip, a brush, a felt, a spatula, a sinter, a brush, a comb, a woven or a nonwoven. The application may also be carried out with the finger or by directly depositing the composition on the support to be made up, for example by friction in the case of a stick or by spraying or projection using a piezoelectric device or by transfer of a composition layer previously deposited on an intermediate support.

Each composition may, if appropriate, be applied as a base coat coated with a layer of another composition (top coat), for example to impart gloss, or as a coating layer on a layer of another composition, or even between a base layer and a coating layer. Each composition may be packaged in a conditioning device which reveals the color of the composition in the mass.

It can be a container having an at least partially transparent body and / or a packaging device comprising an at least partially transparent closure member. Each composition may be packaged in a device which allows both the color of the composition in the mass and the color of the composition to be seen after application to keratin materials. Each composition may further be packaged in a device which comprises means representative of the color revealed on application, for example a deposit of a layer of the composition or of an ink or varnish comprising the same coloring agents as the composition. Where appropriate, each composition may be packaged with a magnet for modifying the orientation of the multilayer interference pigment particles, when this pigment has a non-zero magnetic susceptibility.

Another aspect of the invention, according to another of its aspects, is a method of presenting a range of cosmetic compositions according to the invention, comprising the steps of: - illuminating at least a first region of a sample of the range with diffuse illumination so as to reveal its color in the mass, - illuminating at least a second region of a sample of the range with directional lighting so as to reveal the interferential color . The first and second regions may be different regions of the same composition sample.

Alternatively, the first and second regions belong to different samples. In another variant, the first and second regions correspond to the same region and the diffuse and directional lighting are applied alternately. The invention also relates to a presentation method in which: - two compositions of the range are illuminated so as to make the same color appear in the mass, - these two compositions are illuminated so as to reveal different colors after application, the multilayer interference pigments of these compositions being different. The invention further relates, in another aspect, to a display 5 comprising: a directional lighting source, a diffuse lighting source, a support for exposing at least one sample of the range, better two samples from different compositions of the range, the source of diffuse lighting and at least one sample, better the two samples, at the source of directional lighting. The invention also relates to a process for making up keratin materials using a composition of a range according to the invention. It can be makeup of the skin, lips, nails, eyelashes, eyebrows or hair. The present invention also relates to a make-up kit comprising: a first composition of a range according to the invention; a second composition comprising a cosmetically acceptable medium and to be applied under or on the first composition. This second composition is for example intended to improve the strength of the first composition and / or to modify the appearance.
