Description

COSMETIC COMPOSITION CONTAINING NITROGEN MONOXIDE IN A MICROPOROϋS CRYSTALLINE SOLID MATERIAL

5 The present invention relates to a cosmetic composition containing nitrogen monoxide adsorbed by a porous crystalline solid material, and to a dyestuff . This composition is intended to be applied to human keratin materials, for instance the skin, the lips, the 10 eyelashes, the eyebrows, the nails or the hair.

The composition is more particularly intended to be applied to the skin or the lips.

The composition of the invention may consist in particular of a makeup product for the human body, 15 lips or integuments, which may in particular have non- therapeutic care and/or treatment properties. The composition of the invention may in particular constitute a product for coating keratin fibres, for instance the eyelashes, the eyebrows and the hair, and 20 more particularly the eyelashes.

The composition according to the invention may be in the form of a mascara, an eyebrow product, an eyeliner or a hair makeup product.

The composition may be a loose or compacted 25 powder, a foundation, a makeup rouge, an eyeshadow, a blusher, a lipstick, a lip balm, a lip gloss, a lip or eye pencil, a mascara, an eyeliner, a nail varnish, an artificial skin tanning product, a hair colouring product or haircare product, or alternatively a body makeup product or skin colouring product.

Patent application WO 05/003032 proposes the use of zeolites as adsorber for nitrogen monoxide and shows that the active agent is released into water and into the blood. The document moreover describes certain known uses of nitrogen monoxide and suggests using nitrogen monoxide adsorbed into zeolites in cosmetics. However, the said document does not envisage combining a pigment with this active agent to modify the makeup and to obtain novel effects.

The inventors have found that novel colouring effects may be obtained by combining standard dyestuffs with nitrogen monoxide adsorbed into zeolites. The natural coloration of keratin materials caused by the release of the nitrogen monoxide modifies the makeup result produced by the dyestuff usually used in cosmetic compositions. This combination also makes it possible to design a novel makeup and to conceive of novel gestures for users.

One subject of the invention is thus a cosmetic composition containing at least one dyestuff and nitrogen monoxide adsorbed into a microporous crystalline solid material. The composition according to the invention is in particular intended to improve keratin tissues, such as the skin, the hair, the lips, the nails, the eyelashes and the eyebrows. One subject of the invention is also the cosmetic use of said composition.

An other subject of the invention is the cosmetic use of said composition for making up the skin, the eyelashes, the eyelids, the lips or the nails.

In particular, the composition may be a care and/or makeup composition for the human eyelashes or for the preparation of a care and/or treatment composition for human eyelashes.

The composition is especially intended to make the lips pouty and/or to promote their naturally pinkish colour, to improve the look of the complexion (healthy appearance) and/or to reduce the shadows around the eyes.

The composition may also be used to improve the appearance of the lips or the area around the lips, especially to increase the volume of the lips and/or to model them and/or to make them smoother. The composition may also be used to modify the colour of the lips, to make them pinker or more vivid, or even to obtain a "bitten lip" effect.

In particular, the composition is intended: to make the lips pouty, i.e. increase their size, volume and/or thickness and/or give them a more swollen, fleshy look and/or to model them and/or make them smoother and/or stimulate the naturally pinkish colour of the lips; - to stimulate the naturally pinkish colour of the skin and/or give the skin a natural healthy- appearance; to homogenize the complexion and/or promote its radiance and/or luminosity and/or reduce the off- colour or waxy complexion effect; to reduce the bags and/or lighten the shadows around the eyes and/or make the complexion in the area under the eyes uniform with the rest of the face.

In one embodiment or application, the compositions of the present invention are useful for delaying, minimizing, effacing and/or preventing the signs of ageing of the skin, in particular the visible and/or palpable discontinuities of the texture of the skin associated with ageing, thus providing an improvement in the appearance and/or feel of the skin, for example a smoother, more uniform appearance and/or feel. The term "signs of ageing of the skin" means the development of discontinuities of texture such as wrinkles, including fine surface lines and deep coarse wrinkles, the lines on the skin, crevices, bumps, large pores, a flaky appearance, crumbling and/or other forms of inequality or roughness of the skin, loss of elasticity of the skin, sagging (including puffiness in the area of the eyes and the cheeks) , loss of firmness of the skin, loss of skin tone and loss of recovery of the skin after deformation.

For example, the length, depth and/or other dimensions of the lines and/or wrinkles may be reduced, the apparent diameter of the pores may reduce, or the apparent height of the tissue in the immediate proximity of the opening of the pores may reduce.

The compositions of the present invention may also be used for stabilizing or remodelling hypodermic fat or deeper fat. Stabilizing fat, especially in human beings, is generally associated with the appearance of ageing attributed to fat atrophy and also to fat regression in the skin. The methods and compositions described in the present text may contribute towards preventing the formation of wrinkles and promote an improvement in the appearance of deep wrinkles by supporting the vascularization of the skin.

Microporous crystalline solid material

The composition according to the invention contains at least one organic, mineral or hybrid crystalline solid material. The material is solid at atmospheric pressure and at a temperature of about

4O⁰C.

The crystalline solid material is microporous. The pore size is less than or equal to 1 micron, preferably less than or equal to 1000

Angstroms, more preferably less than or equal to 50

Angstroms and more preferably less than or equal to 30

Angstroms . The pores may form a repeating three- dimensional network capable of trapping nitrogen monoxide or a complex of nitrogen monoxide with at least one organic or mineral cation. According to one embodiment, the microporous crystalline solid material is a zeolite. The composition of the present invention may contain nitrogen monoxide adsorbed into a zeolite material. Zeolite materials are a class of aluminosilicate materials that are known and used in various applications, for example ion exchange, gas separation and catalysis (A. Dyer, An Introduction to Zeolite Molecular Sieves, J. Wiley and Sons, 1988) . The zeolites may be of natural origin or prepared synthetically. Zeolites are structures of nanoporous crystalline aluminosilicates consisting of tetrahedra of AIO₄ and SiO₄ linked together via the oxygen peaks. The assembly of the tetrahedra in space forms polyhedra that delimit a network of one-, two- or three-dimensional channels, cages and cavities in which travel cations to points where they equilibrate the negative charges borne by the AIO₄- tetrahedra. The size and arrangement of the tetrahedra differentiate the zeolites. Zeolites may be represented by the general formula Al_ySii-_yθ₄ ^y~. For each aluminium atom in the zeolite structure, a negative charge is equilibrated by a cation external to the framework. These cations may be of mineral or organic nature and may be exchanged by using standard ion-exchange processes (M. E. Davis, Ordered porous materials for emerging applications, Nature, 417, 813, 2002). Zeolites may comprise cations of a transition element as species external to the framework, for example iron, copper or ruthenium, and the nitrogen monoxide forms complexes inside the cavities of the zeolite material. Cations of other elements, for example sodium and potassium, bind nitrogen monoxide less strongly. A person skilled in the art can use standard ion-exchange processes to introduce the required metal ions into a zeolite structure as cations external to the framework (Plank et al . , US patent No. 3 140 249; Preparation, characterization and performance of Fe-ZSM-5 Catalysts, R. Joyner and M. Stockenhuber, J. Phys . Chem. B., 1999, 103, 5963-5976) . Using such techniques, it is possible to incorporate mixtures of cations into zeolite structures.

The zeolites may be in dehydrated form. The amount of nitrogen monoxide charged into the zeolites may be controlled by varying the relative amounts of the cations external to the framework, by controlling their chemical nature and/or the total number of cations present. For example, the number of cations external to the framework present in the zeolite structure may depend on the amount of aluminium present in the framework. More aluminium ions require more cations external to the framework to equilibrate the negative charge.

The chemical nature of the cations external to the framework may also be modified (for example monovalent cations, e.g. Na⁺ and Ag⁺, may be exchanged with divalent cations, for example Fe²⁺ and Cu²⁺, or trivalent cations, for example Ru³⁺ and Fe³⁺) . Each different cation may have a different affinity for NO and the change of cations present in the zeolite framework may be used to control the release of NO. Such an adjustment of the zeolite composition may affect the kinetics with which the nitrogen monoxide is released. For example, a sodium-charged zeolite may bind nitrogen monoxide less strongly than an iron- charged zeolite and release nitrogen monoxide more quickly. A sodium/iron mixed zeolite may release nitrogen monoxide at a rate different to that of a sodium-charged zeolite or an iron-charged zeolite, and such a release of nitrogen monoxide may have a different rate profile.

The zeolite framework may also be chosen to vary the rate of release of nitrogen monoxide. Zeolite frameworks are available in the form of synthetic materials having different structures (Atlas of Zeolite Framework types, fifth Revised Edition, Ch. Baerlocher, W.M. Meier, D. H. Olson, 2001, Elsevier) . For example, the size of the pores and of the channels of the zeolite framework may be varied. For example, zeolite having the LTA structure has apertures defined by 8 pore tetrahedral units (i.e. a ring of 8 atoms of Si/Al and 8 oxygen atoms) . MFI zeolite has a larger ring aperture defined by 10 tetrahedral units, and FAU by an even larger pore aperture of 12 tetrahedral units. The spatial configuration of the pores may also differ from one zeolite to another. For example, certain zeolites have channels that extend in only one direction (one- dimensional channel systems) , whereas others have channel systems that interact in two or three dimensions (two-dimensional or three-dimensional channel systems) . The size, form and spatial configuration of the zeolites may affect the rates of diffusion and of adsorption/desorption of the nitrogen monoxide (NO) and may be used to control the rate of release of NO.

Consequently, the composition of the zeolite material may be adapted so as to control the amount of nitrogen monoxide charged into the zeolite structure and/or the rate at which the nitrogen monoxide is released from the zeolite.

Such zeolite structures may be chosen, without being limited thereto, from the frameworks having the following three-letter codes: LTA, FAU, MFI, MOR, FER, BEA, PEI and SAS (see the website of the International Zeolite Association, www. iza-online . org, for further details regarding the correspondence of the codes with the framework structures of zeolites) . These three-letter codes describe the framework architecture of zeolites, i.e. their structure, but do not describe the composition of the zeolite, which may vary greatly. The three-letter codes are used as a nomenclature system for zeolites.

The zeolites used in the present invention may have the general formula (I) below:

[ (M₁ ⁿ⁺) _x/n (M₂ ^p+) _y/p. . . (M_n ^q+) _v/q] [Al₂Si₁-_ZO₄ ] ( I ) in which Mi and Vi₂ to M_n are independently chosen from

- metal cations external to the framework independently chosen from the group consisting of Li, Na, K, Mn, Ca, Mg, Fe, Cu, Ru, Rh, Co, Ni, Zn and Ag, and

- organic cations such as N(Ri)_a(R2)b⁺ in which R_x and R2 are independently chosen from H, -CH₃, -CH₂CH₃ and -CH₂CH₂CH₃, and a and b are independently 0, 1, 2, 3 or

4 such that a + b = 4, for instance NH₄ ⁺, x ranges from 0 to nz, y ranges from 0 to pz, and v ranges from 0 to qz, on condition that x/n + y/p

+...+ v/q = z, z is the number of silicon atoms replaced with aluminium atoms in the zeolite framework, n+, p+ and q+ are, independently, integers +1, +2 or +3, when the associated cation is a metal cation, or equal to +1 when the associated cation is an organic cation. The zeolites used in the present invention may have the general formula (II) below:

[(Miⁿ⁺)_x/n(M₂ ^p+)_y/p] [Al₂Si₁-ZO₄] (II) in which Mi and M₂ are as defined above, x ranges from 0 to nz, and y ranges from 0 to pz, on condition that x/n + y/p = z .

Preferably, the extraframework metal cations are cations of elements Zn or Mn, more preferably of Zn.

The zeolites may be prepared by ion exchange according to the method described in the book Verified Synthesis of Zeolitic Materials, by Robson H. and Lillerud, K. P., second revised edition, International Zeolite Association, 2001, www. iza-synthesis . org.

Reference may also be made to the examples in patent application WO 05/003032, the content of which is incorporated into the present patent application by reference . Before charging with nitrogen monoxide, the zeolites may be fully or partially dehydrated, for example under vacuum, to remove the water from the zeolite channels. The resulting zeolite may then be exposed to nitrogen monoxide. Typically, the charging with nitrogen monoxide is performed at a temperature of from -100⁰C to 50⁰C. The charging with nitrogen monoxide may be performed with pure NO or with a mixture of NO and of a vector gas such as an inert gas, for example helium, argon or another inert gas, including mixtures thereof. The charging is typically performed at a pressure of between atmospheric pressure and a pressure of 10 bar. The nitrogen monoxide starts to be released when the cosmetic composition is applied to the keratin materials .

The nitric oxide-charged zeolite may be prepared in powder form or in monolithic form. The monoliths may be formed by compressing a zeolite powder or by mixing a pulverulent zeolite with a suitable binder. The suitable binders include, without being limited thereto, ceramic binders, for example silica or alumina, and polymeric binders, for example polysulfone, polyethylene, PET, polystyrene, polytetrafluoroethylene (PTFE) and other polymers.

According to another embodiment, the microporous crystalline solid material is a zeotype. The term "zeotypes" refers to crystalline structures of zeolites type in which all or some of the silicon and/or aluminium atoms are replaced with one or more atoms of elements from columns 2 to 13 of the Periodic Table, in particular with boron(III), gallium(III) , iron (III), chromium (III, IV or V), germanium ( IV) , titanium ( IV) , vanadium (IV or V), cobalt (II) or cobalt (III) atoms. The zeotype may be silicalite (see the article by C. Lamberti, S. Bordiga and A. Zecchina published in the review Rassegna Scientifica, vol. 4, No. 2, December 1999, the content of which is incorporated into the present patent application by reference) .

Processes for preparing titanium and iron zeotypes are described, respectively, in patent applications US 4 480 135 and US 5 110 995. In particular, patent application US 4 480 135 describes the preparation of a titanium silicalite (TS-I) from a reaction mixture comprising a silicon oxide, a titanium oxide, optionally an alkali metal oxide, a nitrogenous organic base and water. Patent application US 5 110 995 describes the preparation of an iron zeotype starting with a mixture comprising a source of silica, a source of iron and, if necessary, a source of Elⁿ⁺ (in which El is an element from periods 2, 3, 4 or 5 of the Periodic Table of the Elements) , a base, an organic surfactant, and optionally a crystallization seed.

The zeolite containing absorbed nitrogen monoxide may be present in the composition in an amount sufficient to improve keratin tissues such as the skin, the hair, the lips, the nails, the eyelashes and the eyebrows .

In particular, the zeolite containing adsorbed nitrogen monoxide is in an amount sufficient to improve the appearance of the lips or the contour of the lips, especially to increase the volume of the lips and/or to model them and/or to make them smoother. The zeolite containing absorbed nitrogen monoxide may also be in an amount sufficient to modify the colour of the lips, to make them pinker or more vivid, or even to obtain a bitten lip effect.

In one embodiment, the zeolite containing adsorbed nitrogen monoxide is in an amount sufficient to delay, minimize, efface and/or prevent the signs of ageing of the skin, in particular the visible and/or palpable discontinuities of the texture of the skin associated with ageing, thus giving an improvement in the appearance and/or feel of the skin, for example a smoother, more uniform appearance and/or feel.

In one embodiment, the zeolite containing adsorbed nitrogen monoxide is in an amount sufficient to stabilize or remodel the hypodermic fat or deeper fat.

Dyestuff

The dyestuff may be any mineral and/or organic compound, having an absorption between 350 and 700 nm, or capable of generating an optical effect, for instance reflection of incident light or interference. The dyestuffs that are useful in the present invention are chosen from any organic and/or mineral pigment known in the art, especially those described in Kirk-Othmer' s Encyclopaedia of Chemical Technology and in Ullmann' s Encyclopaedia of Industrial Chemistry.

For a composition in paste or cast form such as lipsticks or makeup products, from 0.5% to 50%, preferably from 2% to 40% and better still from 5% to 30% of dyestuff is generally used, relative to the total weight of the composition.

The dyestuffs may be mineral and/or organic. Examples of mineral dyestuffs that may be mentioned include titanium dioxide, optionally surface- treated, zirconium oxide or cerium oxide, iron oxide or chromium oxide, manganese violet, ultramarine blue, chromium hydrate and ferric blue.

The pigments in accordance with the invention may also be in the form of composite pigments as described in patent EP 1 184 426. These composite pigments may be composed especially of particles comprising a mineral core, at least one binder for binding the organic pigments to the core, and at least one organic pigment at least partially covering the core.

The dyestuffs may be chosen from dyes, lakes and pigments .

The dyes are, for example, liposoluble dyes, although water-soluble dyes may be used. The liposoluble dyes are, for example, Sudan red, D&C Red 17, D&C Green 6, β-carotene, soybean oil, Sudan brown, D&C Yellow 11, D&C Violet 2, D&C Orange 5, quinoline yellow and annatto. They may represent from 0 to 20% and better still from 0.1% to 6% of the weight of the composition. The water-soluble dyes are especially beetroot juice or methylene blue, and may represent from 0.1% to 6% by weight of the composition (if present) .

The term "lakes" means dyes adsorbed onto insoluble particles, the assembly thus obtained remaining insoluble during use. The mineral substrates onto which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate or calcium aluminium borosilicate, and aluminium. Among the organic dyes that may be mentioned is cochineal carmine. Examples of lakes that may be mentioned include the products known under the following names: D & C Red 21 (CI 45 380), D & C Orange 5 (CI 45 370), D & C Red 27 (CI 45 410), D & C Orange 10 (CI 45 425), D & C Red 3 (CI 45 430), D & C Red 7 (CI 15 850:1), D & C Red 4 (CI 15 510), D & C Red 33 (CI 17 200), D & C Yellow 5 (CI 19 140), D & C Yellow 6 (CI 15 985), D & C Green (CI 61 570), D & C Yellow 1 O (CI 77 002), D & C Green 3 (CI 42 053), D & C Blue 1 (Cl 42 090).

The term "pigments" should be understood as meaning white or coloured, mineral or organic particles intended to colour and/or opacify the composition. The pigments in accordance with the invention may be chosen, for example, from white or coloured pigments, and pigments with special effects such as nacres, reflective pigments or interference pigments. As pigments that may be used in the invention, mention may be made of titanium oxide, zirconium oxide or cerium oxide, and also zinc oxide, iron oxide or chromium oxide and ferric blue. Among the organic pigments that may be used in the invention, mention may be made of carbon black and barium, strontium, calcium (D&C Red No. 7) or aluminium lakes. The nacres or nacreous pigments are iridescent particles, especially produced by certain molluscs in their shell or else synthesized.

The nacres may be present in the composition in a proportion of from 0.001% to 20% and preferably in a proportion of from 1% to 15% of the total weight of the composition. Among the nacres that may be used in the invention, mention may be made of mica coated with titanium oxide, with iron oxide, with natural pigment or with bismuth oxychloride, such as coloured titanium mica.

The pigments may be present in the composition in a proportion of from 0.05% to 30% and preferably in a proportion of from 2% to 20% of the weight of the final composition. The variety of pigments that may be used in the present invention makes it possible to obtain a wide range of colours, and also particular optical effects such as metallic or interference effects. The term "pigments with special effects" means pigments that generally create a coloured appearance (characterized by a certain shade, a certain vivacity and a certain level of luminance) that is nonuniform and that changes as a function of the conditions of observation (light, temperature, angles of observation, etc.)- They are consequently in contrast with white or coloured pigments, which afford a standard opaque, semi-transparent or transparent uniform shade.

Examples of pigments with special effects that may be mentioned include white nacreous pigments such as mica coated with titanium or with bismuth oxychloride, coloured nacreous pigments such as mica coated with titanium and with iron oxides, mica coated with titanium and especially with ferric blue or with chromium oxide, mica coated with titanium and with an organic pigment as defined above, and also nacreous pigments based on bismuth oxychloride. Nacreous pigments that may be mentioned include the nacres

Mention may also be made of pigments with an interference effect not bound to a substrate, for instance liquid crystals (Helicones HC from Wacker) , holographic interference flakes (Geometric Pigments or Spectra f/x from Spectratek) . The pigments with special effects also comprise fluorescent pigments, whether they are substances that are fluorescent in daylight or that produce ultraviolet fluorescence, phosphorescent pigments, photochromic pigments and thermochromic pigments. The composition advantageously contains goniochromatic pigments, for example multilayer interference pigments and/or reflective pigments. These two types of pigment are described in patent application FR 0 209 246, the content of which is incorporated by reference into the present patent application.

The composition may contain reflective pigments, which may or may not be goniochromatic pigments, and may or may not be interference pigments.

Their size is compatible with the exhibition of a specular reflection of visible light (400-700 ran) of sufficient intensity, taking into account the mean gloss of the composition, to create a bright spot. This size can vary according to the chemical nature of the particles, their shape and their capacity for specular reflection of visible light.

The reflective particles will preferably have a size of at least 10 μm, for example between about 20 μm and about 50 μm.

The term "size" denotes the size given by the statistical particle size distribution to half of the population, which is noted D50. The size of the reflective particles may depend on their surface state. The more reflective this surface state, the smaller may be the size, in principle, and vice versa.

Reflective particles that may be used in the invention, with a metallic or white glint, may, for example, reflect the light in all the components of the visible range without significantly absorbing one or more wavelengths. The spectral reflectance of these reflective particles may, for example, be greater than 70%, and better still at least 80%, or even 90% or 95%, in the 400-700 nm range.

Whatever their shape, the reflective particles may or may not have a multilayer structure, and, in the case of a multilayer structure, for example at least one layer of uniform thickness, especially of a reflective material, which coats a substrate.

The substrate may be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, especially aluminosilicates and borosilicates and synthetic mica, this list not being limiting.

The reflective material may comprise a layer of metal or of a metallic compound.

The layer of metal or of metallic compound may or may not totally coat the substrate, and the layer of metal may be at least partially coated with a layer of another material, for example a transparent material. It may be preferable for the layer of metal or of metallic compound to totally coat the substrate, directly or indirectly, i.e. with insertion of at least one intermediate metallic or non-metallic layer.

The metal may be chosen, for example, from Ag, Au, Cu, Al, Ni, Sn, Mg, Cr, Mo, Ti, Pt, Va, Rb, W, Zn, Ge, Te, Se and alloys thereof. Ag, Au, Al, Zn, Ni, Mo, Cr, Cu and alloys thereof (for example bronzes and brasses) are preferred metals.

In the case especially of particles with a substrate coated with silver or gold, the metallic layer may be present in a content representing, for example, from 0.1% to 50% or even between 1% and 20% of the total weight of the particles.

Particles of glass coated with a metallic layer are described especially in documents

JP-A-09 188 830, JP-A-IO 158 450, JP-A-10 158 541, JP-A-07 258 460 and JP-A-05 017 710.

Particles with a glass substrate coated with silver, in the form of platelets, are sold under the name Microglass Metashine REFSX 2025 PS by the company Toyal . Particles with a glass substrate coated with nickel/chromium/molybdenum alloy are sold under the name Crystal Star GF 550 and GF 2525 by this same company. Irrespective of their shape, the reflective particles may also be chosen from particles with a synthetic substrate coated at least partially with at least one layer of at least one metallic compound, especially a metal oxide, chosen, for example, from titanium oxides, especially TiO₂, iron oxides, especially Fe₂O₃, tin oxide, chromium oxide, barium sulfate and the following compounds: MgF2, CrF₃, ZnS, ZnSe, SiO₂, Al₂O₃, MgO, Y₂O₃, SeO₃, SiO, HfO₂, ZrO₂, CeO₂, Nb₂O₅, Ta₂O₅, MoS₂ and mixtures or alloys thereof. Examples of such particles that may be mentioned include particles comprising a synthetic mica substrate coated with titanium dioxide, or particles of glass coated either with brown iron oxide or with titanium oxide, tin oxide or a mixture thereof, for instance those sold under the brand name Reflecks^® by the company Engelhard. Pigments of the Metashine 1080R range sold by the company Nippon Sheet Glass Co. Ltd., are also suitable for the invention. These pigments, described more particularly in patent application JP 2001-11340, are flakes of C-Glass comprising 65% to 72% SiO₂, coated with a layer of titanium oxide of rutile type (TiO₂) . These glass flakes have a mean thickness of 1 micron and a mean size of 80 microns, i.e. a mean size/mean thickness ratio of 80. They have blue, green, yellow or silvery glints depending on the thickness of the TiO₂ layer.

Mention may also be made of particles of between 80 and 100 μm in size, comprising a synthetic mica substrate (fluorophlogopite) coated with titanium dioxide representing 12% of the total weight of the particle, sold under the name Prominence by the company Ninon Koken.

The reflective particles may also be chosen from particles formed by a stack of at least two layers with different refractive indices. These layers may be of polymeric or metallic nature and may especially include at least one polymer layer. Such particles are described especially in WO 99/36477, US 6 299 979 and US 6 387 498. As illustrations of the materials that can constitute the various layers of the multilayer structure, it is possible to mention, this list not being limiting: polyethylene naphthalate (PEN) and its isomers, polyalkylene terephthalates and polyimides. Reflective particles comprising a stack of at least two layers of polymers are sold by the company 3M under the name Mirror Glitter. These particles comprise layers of 2,6-PEN and of polymethyl methacrylate in an 80/20 mass ratio. Such particles are described in patent US 5 825 643.

The composition may contain one or more goniochromatic pigments.

The goniochromatic colouring agent may be chosen, for example, from multilayer interference structures and liquid-crystal colouring agents.

In the case of a multilayer structure, it may comprise, for example, at least two layers, each layer, which may or may not be independent of the other layer (s), being made, for example, from at least one material chosen from the group consisting of the following materials: MgF₂, CeF3, ZnS, ZnSe, Si, Siθ2, Ge, Te, Fe₂O₃, Pt, Va, Al₂O₃, MgO, Y₂O₃, S₂O₃, SiO, HfO₂, ZrO₂, CeO₂, Nb₂O₅, Ta₂O₅, TiO₂, Ag, Al, Au, Cu, Rb, Ti, Ta, W, Zn, M0S2, cryolite, and alloys, polymers and combinations thereof.

The multilayer structure may or may not have, relative to a central layer, symmetry in the chemical nature of the stacked layers.

Examples of symmetrical multilayer interference structures that may be used in the compositions prepared in accordance with the invention are, for example, the following structures: Al/Siθ₂/Al/SiC>₂/Al, pigments having this structure being sold by the company Dupont de Nemours;

Examples of pigments with a polymeric multilayer structure that may be mentioned include those sold by the company 3M under the name Color Glitter.

The liquid-crystal colouring agents comprise, for example, silicones or cellulose ethers onto which are grafted mesomorphic groups. Examples of liquid-crystal goniochromatic particles that may be used include, for example, those sold by the company Chenix and also the products sold under the name Helicone^® HC by the company Wacker. The composition may also comprise dispersed goniochromatic fibres. Such fibres may, for example, have a size of between 200 μm and 700 μm, for example about 300 μm. Interference fibres with a multilayer structure may be used in particular.

The composition may contain at least one fatty substance chosen from oils, waxes and pasty fatty substances. Oil

According to one embodiment of the invention, the composition comprises at least one oil. This oil preferably represents at least 5% by weight and preferably at least 10% by weight relative to the total weight of the composition.

The composition may comprise a polar or apolar oil, or a mixture of the two. The term "polar oil" means an oil composed of chemical compounds comprising at least one polar group. The polar groups are well known to those skilled in the art; they may be, for example, groups of alcohol, ester or carboxylic acid type.

The apolar oils comprise oils that have a mean solubility parameter at 25⁰C of δ_a = 0 (J/cm³) .

The sparingly polar oils comprise oils that have a mean solubility parameter at 25⁰C of: 0 < δ_a < 5.0 (J/cm³) , especially less than or equal to 4.9, better still less than or equal to 4.5 and better still less than or equal to 4.0 (J/cm³) .

The highly polar oils have a mean solubility parameter δ_a according to the Hansen solubility space, at 25⁰C, of: δ_a > 5.0 (J/cm³)^, especially greater than or equal to 5.3, better still greater than or equal to 5.5 and better still greater than or equal to 6.0 (J/cm³)¹⁴, better still greater than or equal to 7.0 (J/cm³)⁴⁴. The definition and calculation of the solubility parameters in the three-dimensional Hansen solubility space are described in the article by CM. Hansen: "The three dimensional solubility parameters" J. Paint Technol. 39, 105 (1967).

According to this Hansen space:

- δ_D characterizes the London dispersion forces derived from the formation of dipoles induced during molecular impacts;

- δ_p characterizes the Debye interaction forces between permanent dipoles and the Keesom interaction forces between induced dipoles and permanent dipoles;

- δ_h characterizes the specific interaction forces (such as hydrogen bonding, acid/base, donor/acceptor, etc.);

- δ_a is determined by the equation: δ_a = (δ_p ² +

Oh ) •

The parameters δ_p, δ_h, δ_D and δ_a are expressed in (J/crα³)^.

When the oily phase is a mixture of different oils, the solubility parameters of the mixture are determined from those of the compounds taken separately, according to the following relationships: δ_Dmixt = Σ xi δ_Di; δp_mixt = Σ xi δ_pi and δhmixt = ∑ xi δ_hi i i i

Oamixt ⁼ V O pmixt ' ° hmixt) in which xi represents the volume fraction of compound i in the mixture. It is within the capability of a person skilled in the art to determine the amounts of each oil to obtain an oily phase that satisfies the desired criteria. The apolar or sparingly polar oil may be a hydrocarbon-based oil.

The term ^Nλhydrocarbon-based oil" means an oil ,,formed essentially from, or even consisting of, carbon and hydrogen atoms, and possibly oxygen or nitrogen atoms, and containing no silicon or fluorine atoms. It may contain alcohol, ester, ether, carboxylic acid, amine and/or amide groups .

These non-volatile highly polar oils may represent from 0.1% to 30% of the total weight of the composition, for example from 1% to 20% and especially about 10% by weight relative to the total weight of the composition. The composition may thus contain an oily phase, comprising one or more oils, which may themselves be polar or apolar, and volatile or nonvolatile.

Tacky wax According to one embodiment, the composition comprises at least one ^%Λtacky" wax, i.e. a wax with a tack of greater than or equal to 0.1 N.s.

The wax is generally a lipophilic compound that is solid at room temperature (25°C) , with a solid/liquid reversible change of state, having a melting point of greater than or equal to 30⁰C, which may be up to 120⁰C.

By bringing the wax to the liquid form

(melting) , it is possible to make it miscible with oils and to form a microscopically uniform mixture, but on cooling the mixture to room temperature, recrystalliza- tion of the wax in the oils of the mixture is obtained.

In particular, the waxes that are suitable for the invention may have a melting point of greater than 45⁰C approximately, better still greater than or equal to 5O⁰C and in particular greater than or equal to 55°C.

The melting point of the wax may be measured using a differential scanning calorimeter (DSC) , for example the calorimeter sold under the name MDSC 2929 by the company TA Instruments.

The measuring protocol is as follows: A sample of 5 mg of product placed in a crucible is subjected to a first temperature rise ranging from 0⁰C to 12O⁰C, at a heating rate of 10°C/minute, it is then cooled from 120⁰C to 0⁰C at a cooling rate of 10°C/minute and is finally subjected to a second temperature increase ranging from 0⁰C to 120⁰C at a heating rate of 5°C/minute. During the second temperature increase, the variation of the difference in power absorbed by the empty crucible and by the crucible containing the sample of product is measured as a function of the temperature. The melting point of the compound is the temperature value corresponding to the top of the peak of the curve representing the variation in the difference in absorbed power as a function of the temperature. The waxes that may be used in the compositions according to the invention are chosen from waxes that are solid and rigid at room temperature, of animal, plant, mineral or synthetic origin, and mixtures thereof. The tacky wax used may especially have a tack ranging from 0.1 N.s to 10 N.s, in particular ranging from 0.1 N.s to 5 N.s, preferably ranging from 0.2 N.s to 5 N.s and better still ranging from 0.3 N.s to 2 N.s. The tack of the wax is determined by measuring the change in force (compression force or stretching force) as a function of time, at 2O⁰C, using the texturometer sold under the name "TA-XT2^®" by the company Rheo, equipped with a stainless-steel cylinder 2 mm in diameter.

The measuring protocol is as follows:

The wax is melted at a temperature equal to the melting point of the wax + 10⁰C. The molten wax is poured into a container 25 mm in diameter and 20 mm deep. The wax is recrystallized at room temperature (25⁰C) for 24 hours such that the surface of the wax is flat and smooth, and the wax is then stored for at least 1 hour at 2O⁰C before measuring the tack. The texturometer spindle is displaced at a speed of 0.1 mm/s then penetrates the wax to a penetration depth of 0.3 mm. When the spindle has penetrated the wax to a depth of 0.3 mm, the spindle is held still for 1 second (corresponding to the relaxation time) and is then withdrawn at a speed of 0.5 mm/s .

The tacky wax that may be used generally has a hardness of less than or equal to 3.5 MPa, in particular ranging from 0.01 MPa to 3.5 MPa, especially ranging from 0.05 MPa to 3 MPa.

The hardness is measured according to the protocol described above.

Tacky waxes that may be used include a C₂Q-C₄₀ alkyl (hydroxystearyloxy) stearate (the alkyl group containing from 20 to 40 carbon atoms) , alone or as a mixture .

Such a wax is especially sold under the names "Kester Wax K 82 P^®", and "Kester Wax K 80 P^®" by the company Koster Keunen.

The waxes mentioned above generally have a starting melting point of less than 45°C.

The composition according to the invention may comprise a total content of waxes ranging from 5% to 50%, preferably from 5% to 40% by weight and more particularly from 10% to 35% by weight, relative to the total weight of the composition.

The wax(es) (including the tacky wax) may be present in the form of an aqueous microdispersion of wax. The expression "aqueous microdispersion of wax" means an aqueous dispersion of wax particles in which the size of the said wax particles is less than or equal to about 1 μm. Wax microdispersions are stable dispersions of colloidal wax particles, and are described especially in "Microemulsions Theory and Practice", L. M. Prince Ed., Academic Press (1977) pages 21-32.

In particular, these wax microdispersions may be obtained by melting the wax in the presence of a surfactant, and optionally of a portion of water, followed by gradual addition of hot water with stirring. The intermediate formation of an emulsion of the water-in-oil type is observed, followed by a phase inversion, with final production of a microemulsion of the oil-in-water type. On cooling, a stable microdispersion of solid wax colloidal particles is obtained.

The wax microdispersions may also be obtained by stirring the mixture of wax, surfactant and water using stirring means such as ultrasound, high-pressure homogenizers or turbomixers. The particles of the wax microdispersion preferably have mean sizes of less than 1 μm (especially ranging from 0.02 μm to 0.99 μm) and preferably less than 0.5 μm (especially ranging from 0.06 μm to 0.5 μm) . These particles consist essentially of a wax or a mixture of waxes. However, they may comprise a small proportion of oily and/or pasty fatty additives, a surfactant and/or a common liposoluble additive/active agent. When the wax or the mixture of waxes is present in the compositions according to the invention in the form of an aqueous dispersion of particles, the size of the particles, expressed as the mean "effective" volume diameter D[4,3], may be advantageously less than or equal to 1 μm and especially less than or equal to 0.75 μm.

The wax particles may have varied shapes. They may especially be spherical. The composition may contain at least one wax other than that mentioned above.

The wax may have a hardness ranging from 0.05 MPa to 30 MPa, the hardness being determined via the method described above for the fatty phase.

It is especially possible to use hydrocarbon- based waxes, for instance beeswax, lanolin wax, lemon wax, orange wax and Chinese insect waxes; rice bran wax, carnauba wax, candelilla wax, ouricury wax, Japan wax, berry wax, shellac wax and sumach wax; montan wax, microcrystalline waxes, paraffins and ozokerite; polyethylene wax, polymethylene wax, the waxes obtained by Fischer-Tropsch synthesis and waxy copolymers, and also esters thereof. Mention may also be made of waxes obtained by catalytic hydrogenation of animal or plant oils containing linear or branched C₈-C₃₂ fatty chains.

Among these waxes that may especially be mentioned are hydrogenated jojoba oil, isomerized jojoba oil such as the trans-isomerized partially hydrogenated jojoba oil manufactured or sold by the company Desert Whale under the commercial reference Iso-Jojoba-50®, hydrogenated sunflower oil, hydrogenated castor oil, hydrogenated coconut oil, hydrogenated lanolin oil and bis (1, 1, 1-trimethylol- propane) tetrastearate sold under the name "Hest 2T-4S" by the company Heterene and bis (1, 1, 1-trimethylol- propane) tetrabehenate sold under the name Hest 2T-4B EP2006/002663

The invention is illustrated in greater detail in the examples that follow. The percentages are given on a weight basis.

Example 1: Preparation of Zn-NO and Mn-NO zeolites The Zn-NO and Mn-NO zeolites are prepared according to Example 2b of patent application WO 2005/003032, which is incorporated herein by reference.

A zeolite-A synthesized according to the procedure given by Robson H. & Lillerud, K. P. in Verified syntheses of Zeolitic Materials, International Zeolite Association (2001) ; www .iza-synthesis.org, is used.

The sodium ions are then replaced with transition metal cations known for binding nitrogen monoxide (e.g.: Mn²⁺ or Zn²⁺), in order to obtain ion- exchange zeolites, according to the following protocol: sodium zeolite-A (5 g) is placed in a 0.05 M solution of metal acetate (400 ml, distilled water) and dried at 100⁰C overnight. Analysis of the zeolites is performed using an Agilent 7500 ICP-MS spectrometer.

The zeolites A containing Mn or Zn, respectively, are then dehydrated.

0.3 g of Mn or Zn zeolite-A thus prepared is dehydrated for 2 hours at 300⁰C (0.5 mmHg) . It is then cooled to room temperature and exposed to a nitrogen monoxide/helium gaseous mixture (10% NO, 90% He) at a pressure of 3 atmospheres for 10 minutes, and then exposed again to nitrogen monoxide at a pressure of 3 atmospheres. This step is repeated three times.

The capacity of the NO to be released in the presence of a flow of argon (either saturated with water vapour or taken directly from a gas cylinder, 5 ml min^"1) is then measured. The gas is then bubbled through a phosphate-buffered saline solution (pH 7.4, 10 ml) into which a precalibrated nitrogen monoxide electrode (World Precision Instruments, ISO-NO Mark II) is immersed. The concentration of NO released over time is thus measured. Example 2 : lip gloss
