Description
WO 00/38658 PCT/FR99/03051 SPRAYABLE COSMETIC COMPOSITION AND MATRIX WHICH MAY BE USED IN THIS COMPOSITION FOR DERMAL ADMINISTRATION The present invention relates to a novel 5 composition for dermal administration of an active substance or active principle. This composition may be a cosmetic composition, for example a slimming composition. The terms "active principle" and "active 10 substance(s)" mean one or more medicinal or non medicinal active principles. It may thus be, for example, a peptide or non-peptide compound, a cell or tissue extract of animal or plant origin or a product obtained by fermenting a microorganism, for example a 15 bacterium or a fungus. Thus, in the present description, the terms "active principles" and "active substance(s)" will be used without discrimination, according to the definitions given above. More specifically, the invention relates to a 20 composition for dermal administration which is capable of forming a supple film after drying on the skin, and also to a matrix which may be used in such a composition. The dermal administration of active 25 substances is an advantageous technique, endowed with certain advantages such as the absence of side effects.
2 However, in order to be effective, this technique must allow penetration into the skin over a prolonged period and in a manner which is sufficient to reach the intended cells and obtain the desired effect. 5 To date, various systems or devices for this type of administration have been proposed. They make it possible to introduce controlled doses of active substances. For example, the transdermal administration 10 device known commonly as a "patch" is known, this device consisting of a reservoir formed from synthetic plastics containing the active principle. This reservoir may be covered, on its face in contact with the skin, with a microporous membrane whose 15 permeability to the active substance regulates its diffusion and consequently its dosage. Despite the genuine possibilities offered by this device, in particular for an application, other systems may be preferred to it. The reason for this is 20 that it is known that the patch may become detached from the skin and that it may moreover often have an unsightly appearance. Gels containing active substances have also been proposed. However, this mode of use may have 25 certain drawbacks in practice, generally a sticky feel which is unpleasant for the person using it, and also difficulty in controlling the dose administered.
3 Other systems which help in transdermally administering active substances have also been reported. In this respect, mention may be made of 5 sprayable compositions especially comprising polymers capable of forming a film on contact with the skin and of releasing the active principle, for transcutaneous administration. Compositions of this type, disclosed, for example, in patent EP 319 555, comprise an active 10 principle, a polymer matrix forming a supple film after drying, a solvent for controlling the release of the active substance, namely a sorbitan macrogollaurate, a parrafin, a medium-chain fatty acid diglyceride or triglyceride or propylene carbonate, and also a 15 solvent, for the matrix, which is capable of evaporating on the skin, and finally a propellant for spraying this composition contained in a suitable device. Furthermore, due to the presence of 20 polymethacrylic derivatives, the compositions of patent EP 319 555 give a characteristic odor which is relatively unpleasant for the user and those in his or her vicinity. Other pharmaceutical compositions for topical 25 administration containing an active principle, a solvent and various other ingredients are also known.
4 By way of example, mention may be made of patent EP 55396 which discloses antimycotic compositions formed: e from a cellulose ether 5 e from 2% to 10% of a spreading agent such as isopropyl myristate or isopropyl palmitate e from 1% to 8% of a solubilizing agent * from 0.05% to 1% of active principle, and e from a solvent such as isopropanol. 10 However, although these compositions may be used for dermatological topical applications, they are found to be entirely unsuitable for application by spraying, even after adding from 10% to 40% of a propellent gas as recommended, since they appear to be 15 too viscous and liable to have various drawbacks such as blockage of the spraying device. Mention may also be made of patent EP 319 964 which discloses antifungal compositions capable of forming a film, comprising: 20 e from 0.1% to 1.5% of tolnaphthalate e from 10% to 20% of a dimethylaminoethyl methacrylate/methacrylate copolymer e from 0.5% to 10% of a fatty acid ester e a solvent of alcohol type and optionally from 0.1% 25 to 5% of a cellulose derivative. This composition does not appear to be suitable for spraying either. In addition, as already 5 mentioned previously, the presence of methacrylic derivatives gives it an acceptable odor. Mention may also be made of patent EP 289 900 which relates to antibacterial compositions for topical 5 use, comprising: e from 0.5% to 10% of an antibacterial active principle e from 1% to 30% of a water-insoluble polymer, in particular ethylcellulose or a 10 polyvinylpyrrolidone copolymer e from 0.5% to 40% of a plasticizer, generally an essential oil, which also acts as a transcutaneous absorption promoter e from 50% to 95% of a solvent such as ethanol. 15 Finally, mention may be made of patent application WO 96/30000, the main subject of which is a pharmaceutical composition for transdermal administration, comprising: 1) a polymeric release matrix capable of forming a 20 supple film after drying 2) an active principle 3) a promoter of transcutaneous absorption of the active principle 4) a physiologically acceptable non-aqueous solvent 25 capable of dissolving the release matrix, the active principle and the transcutaneous absorption promoter, and also of being rapidly removed by 6 evaporation on contact with the skin, which is intended, after administration of the medicinal substance, to bring about a preventive or therapeutic response. 5 The medicinal product particularly used in said patent application is estradiol. The search for a composition allowing the diffusion of active substances through the dermis, from an area of low coverage and at rates that are 10 compatible with a treatment while at the same time being free of the drawbacks reported previously, thus remains of major interest. Now, it has been discovered, surprisingly, according to the invention, that it is possible to 15 provide compositions, more particularly cosmetic compositions for dermal administration, using a film formed on the skin, these compositions lacking the drawbacks mentioned above but being capable, using a small and controllable area of coverage, of delivering 20 the active substance uniformly, continuously and at rates largely reaching the possibility of achieving the desired effect. Thus, one subject of the invention is a cosmetic composition for dermal administration, 25 comprising: 1) a polymeric release matrix capable of forming a supple film after drying, 7 2) one or more active substances, 3) a promoter of cutaneous absorption of the active principle, 4) a non-aqueous solvent capable of dissolving the 5 release matrix, the active principle and the cutaneous absorption promoter and also of being rapidly removed by evaporation on contact with the skin, 5) at least one propellent gas. 10 In the present context, both in the description and in the claims, the term "[lacuna]" means either a substance which is intended, after administration, to bring about a preventive or curative response, or a combination of two or more substances of 15 this type. The polymeric matrix is generally chosen from polymeric or copolymeric substances capable both of forming a supple film after evaporation of the solvent and of releasing the active substance. 20 This matrix is formed in the stratum corneum after evaporation of the solvent capable of releasing the active substances. This matrix is generally present in a proportion of from 0% to 7% relative to the weight of 25 the composition according to the invention, for instance from 4% to 7%, for example 3%. From 1% to 5% 8 by weight of matrix and in particular 3% is preferably used. The choice of this matrix will relate mainly to polymeric or copolymeric substances that are soluble 5 in the physiologically acceptable solvent so as to form a homogeneous solution. Among the polymers or copolymers capable of satisfying the above criteria, those more particularly selected are cellulose polymers or copolymers, 10 especially because they have a suitable abrasion strength and mechanical stability after drying. For this reason, cellulose matrices of this type may be placed in contact with water without any fear of deterioration. 15 As examples of cellulose polymers or copolymers which may be used in the compositions of the invention, mention may be made of ethylcellulose, cellulose acetate butyrate, cellulose acetate propionate or a hydroxypropylmethylcellulose which may 20 or may not be grafted, such as hydroxypropylmethylcellulose acetate succinate. However, ethylcellulose represents the preferred cellulose polymer and, consequently, the polymeric release matrix of choice for the formation of 25 a film which is supple on contact with the skin. In addition, the polymeric matrix may consist of a vinylpyrrolidone/vinyl acetate copolymer such as 9 polyvinylpyrrolidone/vinyl acetate, referred to hereinbelow as PVP/VA. Consequently, according to another of its aspects, a subject of the invention is a cosmetic 5 composition for dermal administration, comprising: 1) a polymeric release matrix capable of forming a supple film after drying, chosen from cellulose polymers or copolymers and vinylpyrrolidone/vinyl acetate copolymers, 10 2) active substances, 3) a promoter of cutaneous absorption of the active principle, 4) a non-aqueous solvent(s) capable of dissolving the release matrix, the active principle and the 15 cutaneous absorption promoter and also of being rapidly removed by evaporation on contact with the skin, 5) at least one propellent gas. As regards the active substance, it will be 20 chosen from substances that are soluble in the solvent and capable of continuously crossing the epidermis and/or the dermis with a flow which is sufficient to give an effective concentration using a small but sufficient area of skin. 25 These active substances will be incorporated into the compositions of the invention in a proportion, in particular, of from 0.1% to 20% relative to the 10 weight of these compositions, it being understood that each active substance will be introduced at individualized concentrations known in the art for dermal administration or at concentrations adapted to 5 this route of administration. In order to achieve an effective concentration of active principle without, however, using too large an area of skin, a cutaneous absorption promoter is combined with the polymeric matrix and the 10 active principle. This promoter is advantageously incorporated in the compositions of the invention in a proportion of from 15% to 30% relative to the weight of this composition, preferably from 15% to 25%, for example 20%. 15 This absorption promoter is chosen such that it can bring large dermal flows in order to obtain the desired effects by means of an acceptable skin coverage, i.e. a coverage of less than 150 cm 2 but preferably between 10 and 40 cm2, for example 30 cm 2 . 20 In order to be effective, the skin absorption promoter under consideration must be capable of transiently disorganizing the skin barrier so as to increase the permeability of the skin without irritating it, while at the same time promoting the 25 diffusion of the active principle chosen according to kinetics and a concentration which are sufficient and which may be maintained for a certain amount of time.
11 This skin absorption promoter will be selected from substances that are compatible with the non-aqueous solvent capable of rapidly evaporating on contact with the skin. It will preferably be selected 5 from the following compounds which have the required degree of solubility in the physiological solvent under consideration and which combine the best qualities reported above, that is to say: e esters of aliphatic fatty acids, essentially 10 esters containing in total from 10 to 30 carbon atoms optionally substituted with one or two hydroxyl, carboxylic or C 1
-C
4 acyloxy groups such as acetoxy, or optionally interrupted with one or two ethylenic bonds or with one or two ether 15 oxygens, e aliphatic fatty alcohols, essentially C 1 0
-C
3 0 alcohols optionally substituted with one or two hydroxyl, carboxylic or C1-C 4 acyloxy groups such as acetoxy, or optionally interrupted with one or 20 two ethylenic bonds or with one or two ether oxygens. Absorption promoters that are particularly preferred, which may be selected from the esters of aliphatic fatty acids and aliphatic fatty alcohols 25 mentioned above, are given below, namely: a) aliphatic fatty acid esters of general formula: 12 0 ll R-C-OR, I in which R represents a linear or branched C 2
-C
7 alkyl or alkenyl group optionally substituted with a hydroxyl, carboxylic or C 1
-C
4 acyloxy group and 5 Ri represents a linear or branched C 3
-C
8 alkyl group optionally substituted with one or two hydroxyl groups such as, for example, an isopropyl or 2-ethyldihydroxyethyl group or Ri represents a
-CH
2
-CH
2 -0-(CH 2
)
2 -0-CH 2
-CH
3 group, the aliphatic 10 fatty acid ester comprising a minimum of 10 carbon atoms and a maximum of 2 hydroxyl groups; b) aliphatic fatty acid alcohols of general formula:
R
2 -OH II in which R 2 represents a C 1 0
-C
20 alkyl group. 15 As examples of specific compounds which have shown the best potential for promoting the cutaneous absorption of active substances, mention may be made of: 2-ethylhexyl 2-ethylhexanoate 20 isopropyl myristate diethylene glycol monoethyl ether myristate isopropyl palmitate 2-octyldecanol 2-ethylhexyl undecylenate 25 2-ethylhexyl succinate 2-ethylhexyl 12-hydroxystearate 13 2-ethylhexyl 12-acetoxystearate glyceryl isostearate hexyl laurate isononyl isononanoate 5 2-ethylhexyl palmitate 2-ethylhexyl stearate diethylene glycol monoethyl ether 2-ethylhexyl 2-ethylhexanoate represents the preferred absorption promoter, in particular for 10 cosmetic compositions according to the invention. This compound is sold under the name Dragoxat* and is also known as octyl octanoate. As regards the non-aqueous solvent capable of dissolving the release matrix, the active principle and 15 the cutaneous absorption promoter, it will be selected from compounds with a relatively low boiling point, that is to say a boiling point of less than 100C at atmospheric pressure, such that it can be rapidly removed by evaporation on contact with the skin and 20 similarly help to form a film by drying without, however, causing any local irritation. Such solvents are generally used in a proportion of from 44% to 84.9% relative to the weight of the final composition and may be selected from 25 volatile compounds such as dichloromethane, ethanol, isopropanol and ethyl acetate.
14 Ethanol and isopropanol are solvents of choice. However, ethanol is a preferred solvent according to the invention since it efficiently contributes toward the formation of films on the skin 5 while at the same time rapidly evaporating on contact with the skin. The propellent gases which may be used according to the invention are chosen from: butane 10 propane isobutane carbon dioxide dimethyl ether hydrochlorofluorocarbon 15 hydrofluorocarbon nitrogen isopentane nitrogen oxide pentane 20 Butane or propane is preferred. Consequently, according to one of its particular aspects, the invention relates to a cosmetic composition comprising: 1) from 0% to 7% of a polymeric release matrix 25 capable of forming a supple film after drying, chosen in particular from cellulose polymers or copolymers such as ethylcellulose 15 2) from 0.1% to 20% of an active substance 3) from 15% to 30% of a promoter of cutaneous absorption of the active principle, in particular from 15% to 25% of a fatty acid ester or of a 5 fatty alcohol chosen from: 2-ethylhexyl 2-ethylhexanoate isopropyl myristate diethylene glycol monoethyl ether myristate isopropyl palmitate 10 2-octyldecanol 2-ethylhexyl undecylenate 2-ethylhexyl succinate 2-ethylhexyl 12-hydroxystearate 2-ethylhexyl 12-acetoxystearate 15 glyceryl isostearate hexyl laurate 4) from 44% to 84.9% of a non-aqueous solvent capable of dissolving the release matrix, the active principle and the cutaneous absorption promoter, and also of 20 being rapidly removed by evaporation on contact with the skin, in particular ethanol or isopropanol 5) at least one propellent gas. In the context of the present invention, a sprayable composition to be applied from a dosing 25 vaporizer bottle onto the skin, which is cosmetically satisfactory and whose application area and dose 16 characteristics are controlled and reproducible, has been investigated more particularly. There is thus formation of a "film" on the skin. Active substances may thus be applied according 5 to the invention to the skin in the form of a film. Several biocompatible formulations which promote cutaneous penetration were prepared. The active substances used may be intended for the manufacture of a film, for example a film 10 intended for slimming purposes. In particular, the film according to the present invention relates to a cosmetic composition containing slimming substances. This slimming substance may be a neuropeptide Y receptor antagonist. 15 Neuropeptide Y, referred to hereinbelow as "NPY" for short, is a neuromediator which participates in a certain number of physiological processes and for which an involvement in regulating lipolysis has been demonstrated (P. Valet. J. Clin. Invest. 1990, 85, 291 20 295). It has been disclosed in EP 838 217 that NPY antagonists may be used to prepare cosmetic compositions. These cosmetic compositions containing an 25 NPY-antagonist component may be used as lipolysis/lipogenesis regulators on the skin without, however, interfering with the skin's natural functions.
17 It has also been disclosed that cosmetic slimming compositions containing an NPY-antagonist component and an c2-antagonist component are particularly advantageous. 5 Thus, according to one of its aspects, the present invention relates to a film containing a cosmetic slimming composition containing at least one NPY-antagonist component with another active substance such as an c2-antagonist. The NPY antagonist contained 10 in the cosmetic composition may be a non-peptide compound, a peptide, a cell or tissue extract of animal or plant origin or a product obtained by fermenting a microorganism, for example a bacterium or a fungus. These components are themselves non-peptide 15 synthetic compounds, peptides or products obtained by fermenting a microorganism, for example a bacterium or a fungus, or by extracting cells or tissues of animal or plant origin. Of course, the applied film needs to be well 20 tolerated, but also needs to have an appealing cosmetic appearance with rapid evaporation of the vehicles, leaving little in the way of residues on the surface of the skin. The cosmetic evaluation of a series of 25 formulations applied as a film to the skin was carried out.
18 More particularly, the objective was to characterize all of the cosmetic properties of the spray solutions by means of a sensory analysis study. This is a sensory study according to six 5 criteria identified as being favorable (the implementation of the protocols and the type of calculation adopted correspond to the AFNOR standards published for the agrifood sector). These criteria are as follows: 10 e ease of penetration: absorption and evaporation e the residue: greasy/dry (the feel is evaluated by sliding the index finger over the film deposited) gloss (visual presence of the residue) 15 stickiness (the feel is observed by tapping the film with the index finger) odor e overall assessment of the product: taking into account only the above criteria. 20 The application method is as follows: After priming the pump by pressing several times, the formulation is sprayed onto the skin at a measured distance of 10 cm. The observations begin 10 minutes after the application, and this duration is 25 standardized for the sensory analysis protocols. One spray corresponds to 130 g1 of formulation onto an area of about 35 to 40 cm 2 19 The excipients used are as follows: e film-forming agent: ethylcellulose 99 N7NF (7 mPa.s: Aqualon) e solvent: isopropanol (SDS), ethanol (Labover), 5 e promoter and texture agent: Dragoxat 0 E.H. (penetrating cosmetic oil: Dragoco), Dow Corning 556 silicone, light liquid paraffin (Sanofi Winthrop Gentilly). The spray system used is as follows: 10 e VP7/130 pump: Valois * push-button dispenser IN3 GP4/5: Valois e 20 ml ONC varnished aluminium can. The formulations contain: e 66% to 67% solvent: ethanol, isopropanol or a 15 combination of the two. e 20% to 30% promoter: Dragoxato E.H. e 3% to 5% ethylcellulose The formulation disclosed in WO 98/30000, which was the subject of studies with estradiol as 20 medicinal agent, serves as reference and will be referred to hereinbelow as (R). The details of the compositions are given in Table A. All the criteria measured and the overall 25 assessment for each formulation are evaluated on a scale ranging from +3 to -4 and reported in the form of histograms.
20 The average values obtained for the ten experimenters are accompanied by the high and low values. The evaluation of the formulations is 5 detailed herein relative to the reference formulation (R) by demonstrating the changes in composition which affect or improve its cosmetic appearance. Table B summarizes the main interpretations regarding the effect of the various excipients relative 10 to the reference formulation. The perception of the reference formulation (R) is improved by limiting the amount of ethylcellulose to 3% (A) (less greasy, less sticky and less residue). An improved sprayability by means of 15 better dispersion of the formulation by the pump of the device is thus obtained. With these 3%, it is even possible to increase the Dragoxato incorporated to 30% while at the same time maintaining very good perception of the sprayed formulation (C). 20 The formulation which is classified immediately after (E) has a slightly larger amount of residue. It still contains 3% ethylcellulose, but the solvent comprises a fraction of isopropanol which is more difficult to spray. The application area must be 25 smaller for the same volume of solution and thus the residue must be thicker on the skin. The formulations which found least favor (B, R, F and G) because they 21 were too greasy or sticky all contain 4 to 5% ethylcellulose. The result is the same with ethanol or isopropanol. No improvement is observed by adding 1% of compound described as optimizing the spraying (silicone 5 or liquid paraffin) (F and G). Formulation (D) gave very dispersed results. It comprises 4% ethylcellulose and 30% Dragoxat . The solution is not easy to spray. The use of ethanol or isopropanol is equivalent in overall terms. 10 The reference formulation is slightly greasy and sticky. By limiting only the amount of ethylcellulose to 0.5 to 3%, the results are much improved and satisfactory. There is little to very little residue, which 15 is rather glossy but is not greasy and is hardly sticky at all. The penetration is quite rapid to very rapid. More particularly, according to the invention, a film formulation containing slimming 20 active agents was developed. These slimming active agents are preferably neuropeptide Y (NPY) receptor antagonists or o2 receptor antagonists. A large number of them are disclosed in patent application EP 838 217. 25 In cosmetology and also in the slimming sector, the cutaneous absorption of an active principle is similar to a passive diffusion, the limiting step 22 being the moment of crossing the horny layer, which is 1000 times more impermeable than the epidermis or the dermis. One of the main advantages expected of the 5 films according to the invention is that of removing this cutaneous resistance to diffusion. This increase in cutaneous absorption is the result of an increase in the moisturization and the temperature of the horny layer, following the semi-occlusion of the site of 10 application, brought about by the film. The expected benefits of slimming films relate mainly to the areas of the body characterized by the presence of stubborn cellulite. For these sites in which cellulite is firmly 15 established, it is necessary to be able to renew and maintain the action of the active substances before they are naturally metabolized by the adipocytes. The technology of films makes it possible, using active substances, to create on the horny layer a 20 reservoir effect, from which a uniform and continuous diffusion of the active agents into the lower layers of the skin is exerted. On account of this continuous diffusion, permanent presence of active agents in the region of the adipocytes is ensured. 25 This results in a constant saturation of the storage receptors, which will make it possible to act 23 on reducing the orange peel effect present in the areas of stubborn cellulite. The advantageous aspect of the films results firstly from the structure of the matrix containing the 5 active substances and secondly from its application system. Since it can be sprayed directly onto the skin, the film forms a thin, supple and invisible film, from which the active substances are diffused. 10 The low thickness of the film formed makes it possible not to disrupt the gaseous and aqueous exchanges existing between the skin and the external environment, thereby further improving the tolerability of the product. The suppleness of the film moreover 15 offers a greater sensation of comfort. As regards the active substances, the film contains NPY antagonist and a2 antagonist active agents, in a concentration 10 times greater than that used in the conventional fluid as disclosed in 20 EP 838 217. Thus, by virtue of its bioavailability which is subject to two-fold control over time, by means of continuous diffusion of the active substances and locally by means of an activity strictly limited to the 25 sites of spraying, the film makes it possible to provide effective and long-lasting saturation of the adipocyte storage receptors by the NPY receptor 24 antagonist and the a2 receptor antagonist, resulting in a reduction of the areas that are traditionally resistant to slimming treatments. The compositions according to the invention 5 for dermal administration may be prepared in a conventional manner, by a person skilled in the art, by mixing together the various constituents in the chosen proportions. For example, the cutaneous absorption 10 promoter may be dissolved, with stirring, in the solvent, followed by addition of the active principle and finally the release matrix. All of the substances forming part of the compositions of the invention are known products or may 15 be prepared by known methods, some of these products being commercially available. The dermal compositions of the invention thus obtained may be applied by any means to an area of skin, for example to an area of between 10 and 40 cm 2 20 for example 30 cm 2 , in particular and preferably by direct spraying using a dosing pump of a type which is known and sold, with the aid of a propellant such as a compressed or liquefied gas. Although the prior art asserts the contrary, 25 it has been found, surprisingly, that a release matrix formed from ethylcellulose does not, with the composition used, cause any obstruction by blocking the 25 outlet of the spraying head nozzle, such that the compositions of the invention may be sprayed in the presence of a propellent gas without any fear of deterioration of the spray container. 5 The compositions of the invention may thus be administered by spraying using a container fitted with metering valve, also containing a propellent gas such as nitrogen or nitrous oxide, or a liquefied gas such as butane or propane. 10 According to another subject, the invention relates to a matrix intended for cosmetic compositions for dermal administration, comprising: a) a polymeric matrix, for releasing an active principle, which is capable of forming a supple 15 film after drying b) a promoter of cutaneous absorption of an active principle c) a non-aqueous solvent capable of dissolving the release matrix and the cutaneous absorption 20 promoter and also of being rapidly removed by evaporation on contact with the skin d) a propellent gas The polymeric matrix will be selected from polymeric and copolymeric substances, in particular 25 from cellulose polymers or copolymers as specified previously, while the cutaneous absorption promoter will be selected from aliphatic fatty acid esters or 26 from aliphatic fatty alcohols as described above, in particular esters of formula I or alcohols of formula II. As regards the non-aqueous solvent, it is a 5 compound with a boiling point of less than 1000C at atmospheric pressure, as mentioned previously. These various components of the matrix for the dermal cosmetic composition will be distributed such that, in the cosmetic composition under 10 consideration containing the active principle, the release matrix represents from 0% to 7%, the cutaneous absorption promoter represents from 15% to 30% and the non-aqueous solvent represents from 44% to 84.9%, these percentages being expressed relative to the weight of 15 the final cosmetic composition. These matrices for dermal compositions according to the invention may be conventionally prepared by mixing together the various ingredients of which they are made in the selected proportions. 20 The propellent gases are advantageously chosen from propanol and butanol. The film-forming compositions of the invention and the matrices for dermal compositions according to the invention have unquestionable 25 advantages since they are capable of bringing about the cutaneous diffusion of an active substance, so as to produce constant and controlled effective levels over a 27 prolonged period of at least 12 hours from an area of skin coverage of about from 10 to 40 cm 2 In addition, the compositions and matrices for dermal compositions according to the invention, 5 while lacking any unpleasant odor, spread out to form a uniform film over the entire area of skin selected. These films are sufficiently supple and abrasion resistant to avoid any deterioration on the skin of the user and exhibit better tolerability than 10 the known dermal devices since, on account of their thinness and the absence of any coverage, gaseous and aqueous exchanges with the external environment are not disrupted. Finally, the compositions of the invention, 15 in the form of a supple film, afford the user a greater sensation of comfort and, by virtue of their transparency, are entirely invisible. Various tests were performed both in vitro and in vivo so as to demonstrate the characteristics 20 and particular features of the compositions of the invention. The cosmetic compositions according to the invention preferably contain slimming active substances. 25 The slimming active substances are preferably chosen from NPY or oC2 receptor antagonists.
28 In this case, the active substances used are, for example, the extracts of the Streptomyces sp strain SEBR 2794, filed at the C.N.C.M. of the Institut Pasteur under No. 1-1332 and the extracts of the 5 Bacillus licheniformis strain SEBR 2464 filed at the C.N.C.M. of the Institut Pasteur under No. 1-1778. They will be referred to hereinbelow as slimming active substance. A clinical efficacy study was carried out 10 with a slimming composition containing NYP and x2 receptor antagonists. The object of this study was to evaluate the efficacy of the film used in combination with Lipofactor® fluid (Lipofactor: registered trademark of Sanofi). 15 a) Protocol The test is carried out over a period of 28 days and is performed on 31 women. The individuals were included after a clinical examination and verification of the presence of areas of established 20 cellulite. The individuals applied the fluid and the film to the same leg, defined randomly, the other leg being used as the untreated control. The fluid is applied in the desired amount to the entire thigh, from the knee to the buttock fold. 25 The application is carried out in the evening, with no massaging beyond that required for penetration of the product.
29 The film is applied in the morning in a highly localized manner to the following 4 sites: * outer superior lateral face of the thigh, * inner superior face of the thigh, 5 * posterior face (buttock fold), * inner face of the knee. The amount of film used per day corresponds to two adjacent sprayings so as to cover the area concerned. 10 The evaluation of the efficacy is performed at To (before treatment) and at T 2 8 days and uses three different methods: * echography to measure the thickness of the adipose tissue taken at three locations on 15 the thigh plus one on the knee; * clinical evaluation of the macrorelief (orange peel effect) of the outer face of the thighs; * analysis of images of the relief of the 20 orange peel effect. b) Results q Echography Table 1 shows the main characteristics of the individuals. 25 The weight of the individuals was measured at the end of the 28 days of the test. No significant changes were observed, which will thereby make it 30 possible to confirm the attribution of the results observed to the activity of the test products. Table 1: Characteristics of the individuals Criteria Average Maximum values Minimum values Age 37 years old 53 years old 19 years old BMI (a) 21.8 26.9 18.5 (a) Body Mass Index 5 Table 2 and Figure 1 show the average reduction in thickness of the adipose tissue after one month of testing. Depending on the area, a marked reduction in the thickness of the adipose tissue, of the order of 10 -10% compared with the values measured at To, is observed.

At the same time, good stability of the controlateral control locations, which show non-significant variations ranging from -0.3 to ±0.1 mm, is observed. q> Clinical evaluation and image analysis 10 The clinical evaluation of the macrorelief is carried out using photographic negatives by five evaluators. After random distribution, all the negatives are graded by the evaluators by comparison with a calibration range (reference photographs), 15 structured around 7 degrees of intensity. For five individuals, a preliminary profilometric analysis was carried out so as to calculate the average relief of a defined area on each 32 image and corresponding to an area of skin equivalent to 3 x 130 mm. The negatives of the outer sides of the treated and control thighs of the 31 volunteers made it 5 possible to confirm clinically, after analysis by the 5 evaluators, an improvement in the skin relief. This improvement is significant (p<<0.05) for the thighs treated between To and T 28 d, whereas, in the same period, no significant result is obtained on the 10 untreated sides. Table 3: Results compared on 5 individuals between the clinical change and the image analysis Individual Clinical change Image analysis (attenuation (improvement) of the skin relief) 1 30% -35% 2 43% -24% 3 18% -14% 4 18% -22% 5 52% -11% The concept of the film was evaluated in the course of the study carried out on 113 women recruited 15 for having cellulite. The film is applied for 4 weeks at a rate of two adjacent sprayings so as to cover the area concerned. The efficacy of the film is evaluated at the end of the study.
33 It emerges from this study, as regards the efficacy, that the film generally allows a significant improvement in the orange peel effect located on the lower limbs. 5 EXAMPLE 1 Dermal composition containing [lacuna] 100 g of a dermal composition having the formulation below is prepared: % by weight 10 Ethylcellulose 6 mPa.s 5% Slimming active substance 2% 2-Ethylhexyl 2-ethylhexanoate 20% Ethanol 73% Propylene glycol 0.5% 15 Propellent gas by mixing together, for 30 seconds and with magnetic stirring, 73 g of ethanol and 20 g of 2-ethylhexyl 2-ethylhexanoate. 2 g of slimming active substance(s) are then added portionwise to the mixture obtained and, 20 after complete dissolution (5 minutes), 5 g of ethylcellulose 6 mPa.s are added with vigorous stirring, so as to avoid the formation of lumps.
