The field of the invention relates to the ^' care and/or the natural make-up of the skin, contour of the eye and/or lips.

The invention relates in particular- to the cosmetic use in a composition of at least one microporous solid- crystal-line material comprising releasable adsorbed nitrogen monoxide NO as agent intended to improve the colour of the skin and/or of the lips and/or the appearance of the lips. Reference' will be made in particular to natural make-up of the skin and/or lips.

In particular, the said NO adsorbed i ^' n the microporous crystalline material which can be released when the composition is applied to the skin and/or lips is , intended to restore fullness to the lips and/or to promote their naturally pink colouring, to improve the appearance of the complexion (good look effect) and/or to reduce periocular lines.

The invention also relates to compositions comprising at least one zeolite comprising releasable adsorbed NO and at least one specific cosmetic active agent and to a cosmetic process for beautifying the skin and/or lips employing the said compositions.

The term "natural make-up" is understood to mean, according to the invention, a means which makes it possible to naturally improve the aesthetic appearance of the skin and/or lips, in contrast to conventional make-up, which employs make-up agents of

dye, pigment and/or filler type which confer an optical effect of colouring and/or of volume intended to conceal the imperfections of the skin and/or to emphasize certain areas of the face. There has always been a search to improve the aesthetic appearance of the skin, in particular the complexion of the ^' skin, and also the contour of the eye, which often reflects the state of tiredness, the mood and/or the age of the subject, or even to render the lips more attractive.

The aim in particular in cosmetics is to promote the clearness and/or the radiance of the complexion and/or to reduce its muddy or waxy appearance and/or to confer a good look effect thereon. This is particularly interesting to people who are not exposed to the sun or are only slightly exposed to the sun.

The prior art teaches, for example, the use in cosmetics of dihydroxyacetone, or DHA, or the use of self-tanning agents for promoting the artificial colouring of the skin.

Lines around the eyes and bags are regarded as unattractive and attempts have always been made to mask them, indeed even to remove them. The formation of "lines around the eyes" is due in particular to a slowdown in the microcirculation of the blood, in particular during the night, resulting in an accumulation of blood pigments in the connective

tissue, visible in particular on getting up in the morning. Furthermore, the lymphatic system, which has also slowed down during the night, results in distension of the eyelids. This distension, in combination with the slackening of the tissues related to age, brings about the formation of the "bags". The aim is thus to reduce periocular lines and/or bags in order to obtain a complexion which is more homogeneous over the entire face. The prior art teaches the use of make-up products (for example: foundation) which make it possible to conceal or tone down skin defects, such as bags and/or lines around the eyes, by an optical effect but these compositions can sometimes give a powdery, indeed even chalky, matt appearance to the skin which can accentuate the defects of the skin. Furthermore, thin lips, in particular in women, are also regarded as unattractive. To increase the thickness of the lips, women have resorted in particular to cosmetic surgery, injection or tattooing techniques and there is a tendency for the use of these techniques to spread, including to women with normal lips who want full or fleshy lips. However, these techniques are expensive, in some cases can give an irreversible result (for example: cosmetic surgery, tattooing) or in other cases can result in side effects of infection or allergy (for example: collagen injection, tattooing, and the like).

As alternative, more cosmetic, solutions, the

Applicant Company has in particular provided, in Patent Application EP 1 382 323, for the use, in a composition for the lips, of at least one goniochromatic colouring agent capable of creating a goniochromatic coloured background which changes according to the angle of observation and/or of incidence of the light, in combination with reflecting particles capable of creating, when the composition is applied to the lips, highlight points which create an optical effect of volume or an effect of fullness.

However, the need remains to find means which make it possible to obtain a natural make-up of the skin of the face and/or lips.

The Applicant Company proposes to use, in a cosmetic composition, a microporous solid crystalline material comprising releasable adsorbed nitrogen monoxide NO in order to meet this expectation. In particular, the microporous solid crystalline material is a zeolite comprising releasable adsorbed NO.

Nitrogen monoxide is known to be involved in numerous biological processes, in particular in the immune system, and has numerous interactions with nucleic acids, proteins, low molecular weight thiols, and the like. The Applicant Company has already provided for the use of NO donors or precursors in cosmetic or dermatological compositions in the fields of the vascularization of the skin or mucous membranes,

of the regulation of the growth of bacteria, of the prevention of damage caused by UV radiation, of slimming, of antiageing, and the like. Due to its gaseous state, NO additionally exhibits the advantage of easily diffusing through the skin or lips or into the surface layers of the skin or lips, making it possible to rapidly obtain the desired effect.

The provision of NO in a form adsorbed in a microporous crystalline material which can be released when the composition comprising it is applied to the skin or lips exhibits the advantage of facilitating the formulation of this gaseous compound in cosmetic compositions .

The prior art teaches the use of zeolites in the chemical industry; they are used in particular as adsorbents or desiccants in the drying of fluids (gases) , as industrial catalysts in the fields of oil refining or petrochemical production, or as agents which are substitutes for phosphates in washing powders.

In the cosmetics field, they are used in particular as odour absorbers, as disclosed in Application US 5 184 630.

Application WO 2005/003032 discloses zeolites comprising releasable adsorbed NO and suggests their use in pharmaceutical compositions intended for the treatment of skin diseases, as well as in hygiene compositions (deodorants, depilatory preparations) or

in antiageing cosmetic compositions.

However, to the knowledge of the Applicant Company, no suggestion has even been made until now to use, in cosmetic compositions, zeolites comprising releasable adsorbed NO for improving the colour of the skin and/or lips and/or the appearance of the lips and for thus obtaining a natural make-up of the skin, contour of the eye and/or lips.

The invention thus relates in particular to the cosmetic use in a composition of at least one microporous solid crystalline material comprising releasable adsorbed nitrogen monoxide NO as agent intended to improve the colour of the skin and/or lips and/or the appearance of the lips. Reference will be made to natural make-up of the skin, contour of the eye and/or lips.

The term "natural make-up" is understood to mean, according to the invention, an aesthetic improvement in the skin and/or lips employing, as active agent, nitrogen monoxide intended to naturally promote, that is to say without the necessary addition of make-up agents with a volume-enhancing or colouring optical effect, the colouring and/or the increase in volume of the skin and/or lips. This natural make-up is also regarded, according to the invention, as a "care make-up" .

In particular, the said NO adsorbed in the microporous crystalline material which can be released

when the composition is applied to the skin and/or lips is intended in particular to: restore fullness to the lips, that is to say to increase their size, their volume and/or their thickness and/or to give them a more swollen or fleshy appearance and/or to model them and/or to render them smoother and/or to stimulate the naturally pink colouring of the lips; stimulate the naturally pink colouring of the skin and/or to confer a good natural look effect on the skin; homogenize the complexion and/or to promote its lustre and/or its radiance and/or to reduce the muddy or waxy complexion effect; - reduce bags and/or to lighten lines around the eyes and/or to render the complexion of the area of the lines around the eyes uniform with the remainder of the face.

The term "microporous solid crystalline material" according to the invention is understood to mean in particular an organic, inorganic or hybrid solid crystalline material.

The material is solid at atmospheric pressure and at a temperature of less than approximately 40 ⁰ C. The solid crystalline material is microporous. The size of the pores is generally less than 1 micron, preferably less than or equal to

1000 angstroms, more preferably less than or equal to

50 angstroms, more preferably less than or equal to 30 angstroms.

The pores can form a repeating three- dimensional network capable of trapping the nitrogen monoxide or a complex of nitrogen monoxide with an inorganic cation or an organic cation.

Mention may in particular be made, as examples of microporous solid crystalline materials which can be used according to the invention, of zeotypes and zeolites.

Use will preferably be made of zeolites, the general formula of which is represented in the oxide form by IMb _n O*A1 ₂ U3' xSiC>2* yføO, in which n is the valency of the cation M, x is the number of silica molecules and y is the number of molecules of water of crystallization.

Zeolite materials constitute a class of aluminosilicate materials which 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).

Zeolites can be of natural origin or can be prepared synthetically. Zeolites are nanoporous crystalline aluminosilicate structures composed of AlO ₄ and SiO ₄ tetrahedra connected to one another via oxygen vertices. Assembling the tetrahedra in space forms polyhedra which delimit a network of 1-, 2- or 3- dimensional channels, cages and cavities in which

cations are positioned at points' where they balance the negative charges carried by the AlO ₄ ^" tetrahedra. The size and the arrangement of the tetrahedra differentiate the zeolites. The zeolite can be represented by the general formula Al _y Sii- _y O ₄ ^y~ . For each aluminium atom in the zeolite structure, one negative charge is introduced and balanced by an extraframework cation. These cations can be inorganic or organic in nature and can be exchanged using standard ion exchange processes (M. E. Davis, Ordered Porous Materials for Emerging Applications, Nature, 417, 813, 2002) .

Zeolites can comprise transition element cations as extraframework entity, for example iron, copper or ruthenium, and 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 extraframework cations (Plank et al., US Patent No. 3 140 249; Preparation, Characterisation and Performance of Fe-ZSM-5 Catalysts, R. Joyner and M. Stockenhuber, J. Phys . Chem. B., 1999, 103, 5963-5976) . By using such techniques, it is possible to incorporate mixtures of cations in zeolite structures.

Zeolites can be in the dehydrated state.

The amount of nitrogen monoxide charged to the zeolites can be controlled by varying the relative amounts of the extraframework cations, by controlling their chemical nature and/or the total number of cations present. For example, the number of extraframework cations present in the zeolite structure can depend on the amount of aluminium present in the framework. More aluminium ions require more extraframework cations to balance the negative charge. The chemical nature of the extraframework cations can also be modified (for example, monovalent cations, for example Na ⁺ and Ag ⁺ , can be exchanged by divalent cations, for example Fe ²⁺ and Cu ²⁺ , or trivalent cations, for example Ru ³⁺ and Fe ³⁺ ) . Each different cation can have a different affinity for NO and changing the cations present in the zeolite framework can be used to control the release of NO. Such an adjustment of the zeolite composition can affect the kinetics under which the nitrogen monoxide is released. For example, a sodium-loaded zeolite can bind nitrogen monoxide less strongly than an iron-loaded zeolite and can release the nitrogen monoxide more rapidly. A sodium/iron mixed zeolite can release the nitrogen monoxide at a different rate from a sodium-loaded zeolite or from an iron-loaded zeolite and such a release of nitrogen monoxide can exhibit a different rate profile.

The zeolite framework can also be chosen in

order to vary the rate of release of the 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 can be varied. For example, the zeolite having the LTA structure has openings defined by 8 pore tetrahedral units (that is to say, a ring of 8 Si/Al atoms and 8 oxygen atoms) . Zeolite MFI has a bigger ring opening defined by 10 tetrahedral units and FAU by an even bigger pore opening of 12 tetrahedral units. The configuration of the pores in space can also differ from one zeolite to another. For example, some zeolites have channels which extend in only one direction (one-dimensional channel systems) , while others have systems of channels which interact in two or three dimensions (2-dimensional or 3-dimensional channel systems) . The size, the shape and the configuration in space of zeolites can affect the rates of diffusion and of adsorption/desorption of the nitrogen monoxide (NO) and can be used to control the rate of release of NO.

Conseguently, the composition of the zeolite material can be adjusted so as to control the amount of nitrogen monoxide charged to the zeolite structure and/or the rate at which the nitrogen monoxide is released from the zeolite.

Such zeolite structures can 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 on the correspondence between the codes and the framework structures of the zeolites) . These three-letter codes describe the framework architecture of the zeolites, that is to say their structure, but they do not describe the composition of the zeolite, which can vary greatly. The three-letter codes are used as nomenclature systems for zeolites.

Zeolites can be prepared by ion exchange according to the method described in the work Verified Synthesis of Zeolitic Materials, Robson H. and Lillerud K. P., Verified Synthesis of Zeolitic Materials, 2nd Revised Edition, International Zeolite Association, 2001, www. iza-synthesis . org.

Reference may also be made to the examples of Application WO 2005/003032, the content of which is incorporated in the present application by reference. Before charging with nitrogen monoxide, the zeolites can be completely or partially dehydrated, for example under vacuum, to remove water from the zeolite channels. The resulting zeolite can subsequently be exposed to nitrogen monoxide.

Typically, charging with nitrogen monoxide is carried out at a temperature of -100 ⁰ C to 5O ⁰ C.

Charging with nitrogen monoxide can be carried out with pure NO or with a mixture of NO and of a carrier gas, such as an inert gas, for example helium, argon or another inert gas, including mixtures of these. Charging is typically carried out at a pressure between atmospheric pressure and a pressure of 10 bar.

Nitrogen monoxide begins to be released when the cosmetic composition is applied to the skin and/or lips. The zeolite charged with nitrogen monoxide can be prepared in the powder or monolith form. The monoliths can be formed by compressing a zeolite powder or by mixing a pulverulent zeolite with an appropriate binder. Appropriate binders comprise, without being limited thereto, ceramic binders, for example silica or alumina, and polymeric binders, for example polysulphone, polyethylene, PET, polystyrene, poly- tetrafluoroethylene (PTFE) and other polymers. According to a specific form of the invention, use is made of a zeolite comprising releasable adsorbed NO of general formula (I) :

[ (Mi ⁿ⁺ )χ _/n (M ₂ ^p+ ) _y/p ...(M _n ^q+ ) _v/q ] [Al ₂ Si ₁ -ZO ₄ ] (I) in which Mi and M ₂ to M _n are chosen independently from extraframework metal cations chosen independently 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 (R ₂ ) b ⁺ , where Ri and R ₂ are chosen independently from H, -CH3, -CH ₂ CBb or

-CH ₂ CH ₂ CH ₃ and a and b are independently 0, 1, 2, 3 or 4 so that a + b = 4, x ranges from zero to nz, y ranges from zero to pz and v ranges from zero to qz, provided that x/n + y/p + ... + v/q = z in which z is the number of silicon atoms replaced by 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, in a cosmetic composition as agent intended to improve the appearance and/or the colour of the skin and/or lips, in particular to promote the natural make-up of the skin, contour of the eye and/or lips.

When Mi and/or M ₂ are small organic cations, NH ₄ ⁺ is preferable.

In particular, the zeolite can have the general formula

[(M ₁ ⁿ⁺ )χ _/n (M ₂ ^p+ ) _y/p ] [Al ₂ Si ₁ - _Z O ₄ ] (II) in which Mi and M ₂ are as defined above, x ranges from zero to nz, and y ranges from zero to pz, provided that x/n + y/p = z.

Preferably, Mi and M ₂ are extraframework metal cations of elements chosen from Zn or Mn, more preferably still Zn.

The NO adsorbed in the zeolites of formula (I) and (II) which can be released when the composition is applied to the skin and/or lips will be intended in particular to: - restore fullness to the lips, that is to say to increase their size, their volume and/or their thickness and/or to give them a more swollen or fleshy appearance and/or to model them and/or to render them smoother and/or to stimulate the naturally pink colouring of the lips; stimulate the naturally pink colouring of the skin and/or to confer a good natural look effect on the skin; homogenize the complexion and/or to promote its lustre and/or its radiance and/or to reduce the muddy or waxy complexion effect; reduce bags and/or to lighten lines around the eyes and/or to render the complexion of the area of the lines around the eyes uniform with the remainder of the face.

The term ""zeotypes" which can be used according to the invention" is understood in particular to mean crystalline structures of zeolite type in which all or part of the silicon and/or aluminium atoms are replaced by one or more atoms of the elements from

Groups 2 to 13 of the Periodic Table, in particular by 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 can be silicalite (see the article by C. Lamberti, S. Bordiga and A. Zecchina which appeared in the review Rassegna Scientifica, Vol. 4, No. 2, December 1999, the content of which is incorporated in the present application by reference) .

Processes for the preparation of titanium and iron zeotypes are disclosed respectively in Patent Applications US 4 480 135 and US 5 110 995. In particular, Patent Application US 4 480

135 discloses 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 discloses the preparation of an iron zeotype from a mixture comprising a source of silica, a source of iron and, if necessary, a source of El ⁿ⁺ (where 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 said microporous solid crystalline material comprising releasable adsorbed NO is present in the composition in a sufficient amount such that the amount of NO which can be released when the composition is applied to the skin and/or lips is effective in producing the desired effect, namely an effect on the natural colouring of the skin (good look effect) , an

effect on the colouring and/or volume of the lips or an effect on the contour of the eye (concealers and/or products for treating bags) . The effect on the complexion, lines around the eyes or lips can be directly measured by simple visual observation or by comparative image analysis.

By way of example, the said zeolite will be present in the composition in an amount such that the amount of NO which can be released on contact with keratinous substances is from 0.001 to 10% by weight with respect to the total weight of the composition, preferably from 0.01 to 5%, better still from 0.01 to 2% and even better still from 0.02 to 1% by weight, with respect to the total weight of the composition. In particular, the zeolite will be present in the composition in an amount ranging from 0.01 to 20% by weight with respect to the total weight of the composition, preferably between 0.1 and 10% by weight, with respect to the total weight of the composition.

The invention is illustrated by the following nonlimiting examples. Example 1 : Preparation of zeolites Zn-NO and Mn-NO

The zeolites Zn-NO and Mn-NO are prepared according to Example 2b of Application WO 2005/003032, incorporated by reference.

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

The sodium ions are subsequently replaced by transition metal cations known for binding nitrogen monoxide (for example: Mn ²⁺ or Zn ²⁺ ), in order to obtain ion-exchange zeolites, according to the following protocol: sodium zeolite A (5 g) is placed in a 0.05M metal acetate solution (400 ml, distilled water) and dried at 100 ⁰ C overnight.

The zeolites are analysed using the Agilent 7500 ICP-MS spectrometer.

The zeolites A respectively comprising Mn or Zn are subsequently dehydrated. 0.3 g of the zeolite A Mn or Zn thus prepared is dehydrated at 300 ⁰ C for 2 hours (0.5 mmHg) . It is subsequently cooled to ambient temperature and exposed to a nitrogen monoxide/helium (10% NO, 90% He) gas

mixture at a pressure of 3 atmospheres for 10 minutes and then exposed again to nitrogen monoxide at a pressure of 3 atmospheres. This stage is repeated 3 times . The ability of the NO to be released is subsequently measured in the presence of a stream of argon (either saturated with water vapour or taken directly from a gas cylinder, 5 ml.min ^"1 ) . The gas is subsequently bubbled into a saline solution of phosphate buffer (pH 7.4, 10 ml) in which a nitrogen monoxide precalibrated electrode (World Precision Instruments, ISO-NO Mark II) is immersed. The concentration of NO released over time is thus measured. The zeolites Mn-NO and Zn-NO thus prepared are subsequently incorporated in the fatty phase of the following dosage formulations.
