Description

The present invention relates to cosmetic compositions, and more

  especially those intended for the makeup of keratin materials. BACKGROUND It is known to incorporate diffractive pigments into make-up compositions in order to provide an iridescent appearance or a light-decomposing effect which induces a change of color as a function of the angle of incidence of the light. or observation. It is known to introduce in the makeup compositions diffusing pigments to produce colors by a phenomenon of absorption of light by specific chromophores. However, the intensity of the color produced by these compositions may be insufficient to lead to a completely satisfactory result. The multilayer interference pigments, comprising a stack of 15 layers whose refractive indexes and thicknesses are suitably chosen in order to generate a color by an interference phenomenon, make it possible to produce a greater intensity of color 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 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 a composition containing a diffusing pigment providing coverage and subsequently depositing a composition by means of a multilayer interference pigment with a second gesture on said base layer. 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. 2908636 2 Abstract There is a need to benefit from a composition 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 invention is a cosmetic composition comprising, in a cosmetically acceptable medium, at least one multilayer interference pigment and at least one diffractive pigment, the coverage of the composition being greater than or equal to 30, the multilayer interference pigment content conferring on the composition in the mass a color which differs from that of the composition after application of a difference E E greater than or equal to 5. The color after application is determined for the purposes of calculating AE after spreading the composition on a contrast map, as for measuring the coverage. 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 invention also offers new possibilities for the marketing of cosmetic compositions, allowing to play at the packaging level on this color variation before and after application. The ratio ml / m 2 between the mass content ml of multilayer interference pigment and the content m2 of diffractive pigment ranges, for example, from 0.1 to 1.5. The mass content of multilayer interference pigment may range from 7 to 20%, more preferably 8 to 15%, especially in the case of a non-pulverulent composition, for example liquid or stick. For a free or compacted powdery composition, the content of multilayer interference pigment is, for example, from 40 to 95%, more preferably 40 to 80%, and more preferably 50 to 80%. The color of the composition in the mass may be white. 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 diffractive pigment (s). The multilayer interference pigment may comprise at least four layers, for example. The multilayer interference pigment may comprise a substrate of a transparent material. The multilayer interference pigment may comprise a substrate made 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 chosen from natural mica, relatively rough, synthetic mica, alumina, silica or glass or metal for a smoother surface. In examples, the composition comprises more than 30% by weight in total of 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 total filler (s). 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 two multilayer interference pigments may have layers made of the same materials but at least one layer of one pigment may have a different thickness than a corresponding layer of the other pigment. 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 stick form, comprising, in a cosmetically acceptable medium: between 7 and 20%, better 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 diffractive pigments. The total content of diffractive pigment (s) may range from 1 to 7%. The subject of the invention is, according to another of its aspects, a pulverulent cosmetic composition (at 25 ° C.) comprising, in a cosmetically acceptable medium: between 40% and 95%, better 50% and 80%, for example between 55% and 50%; and 65% by weight, in total, of one or more multilayer interference pigments, between 0.1 and 60% by weight, in total, of one or more diffractive pigments. The composition may comprise between 1 and 50% by weight of diffractive pigment (s). According to another of its aspects, the subject of the invention is also a packaging unit comprising: a composition as defined above; means for informing the user of 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. Measurement of the covering Liquid compositions (at 25 ° C.) By liquid composition is meant 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 at a thickness of 150 m 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 1A 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 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 reference 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 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 were 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 composition in mass 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). Measurement of color 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 deviation DE is calculated as follows: [(a * *) 2 (L * *) 2 (* _ ~ ù inapplied afterapplicatin + L inlaminate ~ afterapplicatin + L inappliedclass 30 Whiteness index measurement The index of whiteness is calculated from infinite-thickness color measurements and ASTM E313-05 2908636 7 Multilayer Interferential Pigment Multilayer Interferential Pigment is a pigment capable of producing a color by a phenomenon of interference between the radiations The color produced by the multilayer interference pigment may be arbitrary with a plurality of superimposed layers of different refractive indices, in particular a succession of layers of high and low refractive indexes. , for example having a dominant wavelength of between 580 and 650 nm.The color produced by the interfering pigment multilayer integer is not dominant wavelength between 580 and 650 nm. 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 have 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 51 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 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 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 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. 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 20 212G (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) 20 (Colorona) and by Engelhard under the name Super Bronze (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); brown-colored pearlescent agents marketed by the company 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); the nacres with a red glint sold especially by MERCK under the name Sienna fine (17386) (Colorona); nacres with a yellow glint sold especially 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 the company Engelhard under the name Tan opal G005 (Gemtone); black nacres with gold glints sold by the company Engelhard under the name Nu antique bronze 240 AB (Timica), the blue nacres sold especially by Merck under the name Matte Blue (17433) 5 (Microna), the 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 30 at least partially coated with at least one layer of at least one metal oxide, selected for example from titanium oxides, in particular TiO 2, iron oxides in particular Fe 2 O 3, of 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 their mixtures or alloys. 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 coated glass particles of either 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 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, SiO2, Ge, Te, Fe2O3, Pt, Va, Al2O3, MgO, Y2O3, 5203, SiO, HfO2, ZrO2, CeO2, Nb2O5, Ta2O5, TiO2, 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 nature of the different layers, different effects are obtained. Examples of symmetrical interferential multilayer structures are, for example, the following structures: Fe2O3 / SiO2 / Fe2O3 / SiO2 / Fe2O3, a pigment having this structure being marketed under the name SICOPEARL by the company BASF MoS2 / SiO2 / mica-oxide / SiO2 / MoS2; Fe2O3 / SiO2 / mica-oxide / SiO2 / Fe2O3; 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). The liquid crystal coloring agents comprise, for example, silicones or cellulose ethers onto which mesomorphic groups are grafted. As liquid crystal goniochromatic particles, it is possible, for example, to use those sold by CHENIX as well as those marketed under the name HELICONE HC by WACKER. As goniochromatic pigment, it is also possible to use certain nacres, pigments with effects on synthetic substrate, in particular substrate type alumina, silica, borosilicate, iron oxide, aluminum, or interference flakes 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. Diffractive Pigment For the purposes of the present invention, the term "diffractive pigment" denotes a pigment capable of producing a color variation according to the angle of observation when illuminated by white light, because of the presence of a structure which diffracts the light. Such a pigment is still sometimes called a holographic or rainbow pigment. A diffractive pigment may comprise a diffraction grating, capable for example of diffracting in a defined direction an incident monochromatic light ray. The diffraction grating may comprise a periodic pattern, in particular a line, the distance between two adjacent patterns being of the same order of magnitude as the wavelength of the incident light. When the incident light is polychromatic, the diffraction grating will separate the different spectral components of the light and produce a rainbow effect. Reference may be made to the structure of the diffracting pigments in the article Pigments Exhibiting Diffractive Effects by Alberto Argoitia and Matt Witzman, 2002, Society of Vacuum Coaters, 45th Annual Technical Conference, Proceedings 2002, the contents of which are incorporated by reference. The diffractive pigment may be made with patterns having different profiles, in particular triangular, symmetrical or not, in crenellations, of constant width or not, sinusoidal, stepwise. The spatial frequency of the network and the depth of the patterns will be chosen according to the degree of separation of the different orders desired. The frequency may vary for example between 500 and 3000 lines per mm. Preferably, the particles of the diffractive pigment each have a flattened shape, and in particular are platelet-shaped. The same pigment particle may comprise two crossed diffraction gratings, perpendicular or not, of the same linearization or not. The diffractive pigment may have a multilayer structure having a layer of a reflective material, covered at least on one side with a layer of a dielectric material. The latter can impart better rigidity and durability to the diffractive pigment. The dielectric material may then be selected from, for example, the following materials: MgF 2, SiO 2, Al 2 O 3, AlF 3, CeF 3, LaF 3, NdF 3, SmF 2, BaF 2, CaF 2, LiF and their combinations. The multilayer interference pigment and the diffractive pigment may have a substrate in the same material. The reflective material may be chosen for example from metals and their alloys and also from non-metallic reflective materials. Among the metals that can be used are Al, Ag, Cu, Au, Pt, Sn, Ti, Pd, Ni, Co, Rd, Nb, Cr and their materials, combinations or alloys. Such a reflective material may alone constitute the diffractive pigment which will then be monolayer. Alternatively, the diffractive pigment may comprise a multilayer structure comprising a substrate (also called core or core) of a dielectric material covered with a reflective layer at least on one side, or even completely encapsulating the substrate. A layer of a dielectric material may also cover the reflective layer (s). The dielectric material used is then preferably inorganic, and may be chosen for example from metal fluorides, metal oxides, metal sulfides, metal nitrides, metal carbides and their combinations. The dielectric material may be in the crystalline, semicrystalline or amorphous state. The dielectric material, in this configuration, may for example be chosen from the following materials: MgF 2, SiO 2, SiO 2, Al 2 O 3, TiO 2, WO, AlN, BN, B 4 C, WC, TiC, TiN, N 4 Si 3, ZnS, glass particles , diamond-like carbons and their combinations. As a variant, the diffractive pigment may be composed of a preformed dielectric or ceramic material such as a natural lamella mineral, for example peroskovite mica or talc, or synthetic lamellae formed from glass, alumina, SiO2, carbon, iron oxide / mica, mica coated with BN, BC, graphite, bismuth oxychloride, and combinations thereof. In place of a layer of dielectric material, other materials improving the mechanical properties may be suitable. Such materials may include silicone, metal silicides, semiconductor materials formed from Group III, IV and V elements, metals having a centered cubic crystal structure, cermet compositions or materials, glasses. semiconductors, and their varied associations. The diffractive pigment used may in particular be chosen from those described in US patent application US 2003/0031870 published February 13, 2003. A diffractive pigment may comprise, for example, the following structure: MgF 2 / Al / MgF 2, a diffractive pigment having said structure being marketed under the name SPECTRAFLAIR 1400 Pigment Silver by the company FLEX PRODUCTS, 25 or SPECTRAFLAIR 1400 Pigment Silver FG. The proportion by weight of the MgF 2 can be between 80 and 95% of the total weight of the pigment. Other diffractive pigments are marketed under the names Metal Prismatic by the company ECKART. Other possible structures are Fe / Al / Fe or Al / Fe / Al. The size of the diffractive pigment may be, for example, between 5 and 200 μm, more preferably between 5 and 100 μm, for example between 5 and 30 μm. The thickness of the diffractive pigment particles may be less than or equal to 3 m, more preferably 2 m, for example of the order of 1 m.

The composition according to the invention may comprise an aqueous medium and / or a fatty phase, be anhydrous or not. Aqueous or Fatty Phase The composition may comprise water or a mixture of water and hydrophilic organic solvents such as alcohols and in particular lower linear or branched monoalcohols having from 2 to 5 carbon atoms, such as ethanol, isopropanol or n-propanol, polyols such as glycerine, diglycerine, propylene glycol, sorbitol, penthylene glycol, polyethylene glycols. The hydrophilic phase may further contain C 2 ethers and C 2 -C 4 hydrophilic aldehydes.

The medium may comprise a liquid organic phase in which water is dispersed or emulsified. The composition may also have a continuous fat phase, which may contain less than 5% water, especially less than 1% water relative to its total weight and in particular be in anhydrous form. Film-forming agent The medium may comprise a film-forming agent, in particular a film-forming polymer. A film-forming agent is understood to mean an agent capable of forming, by itself or in the presence of an auxiliary film-forming agent, a macroscopically continuous and adherent film on the keratin materials, and preferably a cohesive film, and better still a film of which the cohesion and the mechanical properties are such that said film can be isolatable and manipulable in isolation, for example when said film is produced by casting on a non-stick surface such as a Teflon or silicone surface.
