Title: Cosmetic composition for care and/or makeup, structured with silicone polymers and film-forming silicone resins

Description:
DESCRIPTION  
       [0001] 1. Technical Field  
       [0002] This invention relates to a cosmetic composition for care and/or treatment and/or makeup of the skin, including the scalp and/or the lips of humans, containing a liquid fatty phase comprising at least one silicone oil gelled with a special polymer, existing notably in the form of a cast makeup product, in particular of a makeup stick such as lipsticks, the application of which results in a glossy and non-migrating deposit.  
       [0003] A cosmetic composition for care and/or treatment is a composition which comprises at least one active compound for treating wrinkles, for moisturizing the skin and the lips, for protecting the skin, the lips and the phaneric structures from ultraviolet rays, for treating acne and/or for acting as a self-tanning preparation.  
       [0004] The invention relates most especially to cosmetic and dermatological compositions such as makeup products, possessing properties of staying power, but also of non-transfer and stability.  
       [0005] 2. State of the Prior Art  
       [0006] In cosmetic or dermatological products, it is common to find a structured, that is, gelled and/or rigidified, liquid fatty phase; this is especially the case in cast solid compositions such as deodorants, lip balms and lipsticks, eye shadows, concealers, and foundations. This structuring is obtained with the aid of waxes or fillers. Unfortunately these waxes and fillers have a tendency to make the composition matte, which is not always desirable, in particular for a lipstick or an eye shadow.  
       [0007] In the meaning of the application, by liquid fatty phase is understood a fatty phase which is liquid at room temperature (25° C.) and atmospheric pressure (760 mmHg), consisting of one or more fatty substances which are liquid at room temperature, also referred to as oils, mutually compatible and containing one silicone oil.  
       [0008] In the meaning of the application, by structured liquid fatty phase it is understood that this structured phase does not flow under its own weight.  
       [0009] The structuring of the liquid fatty phase makes it possible in particular to limit its exudation from solid compositions and, in addition, after deposition on the skin or the lips, to limit the migration of this phase into wrinkles and fine lines, which is particularly sought for a lipstick or an eye shadow. In fact, a significant migration of the liquid fatty phase, charged with coloring agents, leads to an unsightly appearance around the lips or the eyes, in particular accentuating wrinkles and fine lines. This migration often is cited by women as a major drawback of conventional lipsticks or eye shadows. By migration is understood an extension of the composition deposited on the skin or the lips beyond its initial border.  
       [0010] Gloss basically is associated with the nature of the liquid fatty phase. Thus it is possible to reduce the level of waxes and fillers in the composition in order to increase the gloss of a lipstick, but then the migration of the liquid fatty phase increases. In other words, the levels of waxes and of fillers required for the making of a stick of suitable hardness place a restriction on the gloss of the deposit.  
       [0011] Document EP-A-1 068 856 [1] describes solid cosmetic compositions, without wax, comprising a liquid fatty phase structured with a polymer, in which the fatty phase is mainly a non-silicone oil.  
       [0012] Document WO-A-01/97758 [2] describes cosmetic compositions based on polyamide resins comprising a gelling agent chosen from among the esters and amides of N-acylamino acids and mixtures thereof. The composition also comprises a polyamide resin solvent which may be chosen from among the saturated or unsaturated fatty alcohols, the esters of fatty and/or aromatic carboxylic acids, the ethoxylated and/or propoxylated alcohols and acids, the silicones, the mineral oils and the branched-chain hydrocarbons; preferably, the esters of fatty acids, the fatty alcohols, the mineral oils, the branched hydrocarbons and mixtures of the latter.  
       [0013] The use of fatty phases based on silicone oils has made it possible up to now to obtain cosmetic compositions having a long staying power when the oils are not very volatile or are nonvolatile, that is, a good staying power particularly of color in the course of time (non-changing, non-fading), and non-transfer compositions when the silicone oils are volatile, not becoming deposited on a support such as a glass, a cup, a fabric or a cigarette, placed in contact with the film of makeup.  
       [0014] At the present time, the use of silicone oils in cosmetics is limited by the lack of molecules capable of gelling these mediums and thus resulting in compositions existing in solid form such as lipsticks or cast foundations, for example. The utilization of cosmetic compositions the fatty phase of which is mainly silicone in most cases results in problems of compatibility with the ingredients traditionally used in the cosmetics industry.  
       [0015] In documents U.S. Pat. No. 5,874,069 [3], U.S. Pat. No. 5,919,441 [4], U.S. Pat. No. 6,051,216 [51], WO-A-02/17870 [6], and WO-A-02/17871 [7], WO-A-99/06473 [12], U.S. Pat. No. 6,353,076 [13], cosmetic compositions such as deodorant sticks or gels were achieved comprising a silicone oily phase gelled with a wax based on polysiloxane and polyamide, or with a polymer containing siloxane groups and groups capable of hydrogen interactions.  
       [0016] In WO-A-02/17870 [6], adding another gelling agent to the composition is contemplated, but the quantities added are to be small, for example less than 0.5% in the case of hydroxystearic acid, to preserve the clearness of the product.  
       [0017] In WO-A-02/17871 [7], using a second gelling agent with the silicone polymer in a quantity representing 0.5 to 2% by weight of the composition, and a solvent system comprising a non-silicone organic compound, a volatile silicone and possibly another silicone also is contemplated.  
       [0018] Document EP-A-1 177 784 [8] illustrates a deodorant composition comprising a liquid phase containing, for example, a volatile silicone and possibly a nonvolatile silicone and/or a non-silicone hydrophobic organic liquid, structured with an organic compound with amido groups, possibly with one or more polymer or non-polymer secondary structuring agents, in smaller proportions. Among the secondary structuring agents, this document mentions the polymers having siloxane groups and groups with hydrogen interactions without giving examples or results on a composition using these polymers.  
       [0019] It should be noted that documents [6], [7] and [8] relate to deodorants for which problems of exudation and migration of the liquid fatty phase charged with a coloring agent into the wrinkles and fine lines, as well as staying power and non-transfer of the composition do not arise as in the case of the makeup cosmetic products described hereinabove. In addition, gloss is not sought for deodorants.  
       [0020] Moreover, the sticks obtained by structuring the liquid fatty phase solely with one or more gelling silicone polymers do not afford a sufficient mechanical resistance to shearing, particularly when the stick is applied on the lips and/or the skin, resulting in a breaking of the stick.  
       STATEMENT OF THE INVENTION  
       [0021] The purpose of the invention is precisely to provide a composition for care and/or makeup and/or treatment of the skin and/or the lips, making it possible to remedy the drawbacks and to solve the problems mentioned previously; in particular the purpose of the invention is to provide a composition having improved deposit staying-power properties.  
       [0022] In a surprising manner, the applicant has found that the use of special polymers combined with one or more film-forming silicone resins made it possible, in the absence of wax, to structure the silicone-oil-based liquid fatty phases in the form of a makeup or care product the application of which resulted in a non-migrating glossy, satiny or matte film in accordance with the wish of the user and/or the type of product sought, and to intensify the staying-power and, possibly, non-transfer properties of these products. In addition, their thermal stability and their slip in application are improved.  
       [0023] By stable is understood a composition which does not exude at room temperature (25° C.) for at least 2 months, or even up to 9 months.  
       [0024] The combination of these special polymers with one or more film-forming silicone resins makes it possible to obtain gels, in particular solid gels, having a good mechanical resistance and a correct rheology for allowing a deposit in sufficient quantity which is not sticky to the touch, affords a very good staying power, does not transfer (in particular when volatile silicone oils are used) and does not migrate into wrinkles and fine lines.  
       [0025] The effects obtained by virtue of this combination of a special polymer and a special silicone resin, notably the surprising improvement in the staying power of the deposit obtained, do not appear in the document of the prior art.  
       [0026] The invention applies not only to products for making up the lips, such as lipsticks, lip pencils, lip glosses, but also to products for care and/or treatment of the skin, including the scalp, and the lips, such as the products in stick form for solar protection of the skin, the face or the lips, or lip balms, to products for making up the skin, of the face as well as of the human body, such as foundations cast in a stick or a dish, concealer products and products for temporary tattooing, to products for cleansing, especially in stick form, and to products for making up the eyes, such as eyeliners, in particular in pencil form, and mascaras, especially cakes for the keratinous fibers (eyelashes, eyebrows, hair).  
       [0027] More precisely, the purpose of the invention is a cosmetic composition for care and/or makeup, comprising:  
       [0028] 1) a liquid fatty phase comprising at least one silicone oil, structured with at least one gelling system comprising at least one polymer (homopolymer or copolymer) with a weight-average molecular mass ranging from 500 to 500,000, containing at least one moiety comprising:  
       [0029] at least one polyorganosiloxane group, composed of 1 to 1000 organosiloxane units in the chain of the moiety or in the form of a graft, and  
       [0030] at least two groups capable of establishing hydrogen interactions, chosen from among the ester, amide, sulfonamide, carbamate, thiocarbamate, urea, thiourea, oxamido, guanidino, biguanidino groups and combinations thereof, on condition that at least one of the groups is other than an ester group,  
       [0031] the polymer being solid at room temperature and soluble in the liquid fatty phase at a temperature of 25 to 250° C., and  
       [0032] 2) at least one film-forming silicone resin, the liquid fatty phase, the gelling system, and the film-forming silicone resin forming a physiologically acceptable medium.  
       [0033] According to the invention, by “gelling system” generally is understood a system making it possible to rigidify the composition by formation of hydrogen bonds.  
       [0034] The composition of the invention can exist in the form of a paste, a solid, a more or less viscous cream. It can be a simple or multiple emulsion, in particular oil-in-water or water-in-oil, water-in-oil-in-water or oil-in-water-in-oil, or a rigid or supple gel with an oily continuous phase. The simple or multiple emulsion can comprise an aqueous or oily continuous phase possibly containing dispersed lipid vesicles. In particular it exists in a form cast in a stick or a dish and more especially in the form of a rigid oily gel in particular anhydrous and notably an anhydrous stick. More especially, it exists in the form of a rigid translucent or opaque gel (depending on whether or not it contains pigments), the liquid fatty phase forming the continuous phase. An anhydrous composition will comprise less than 10% by weight of water, for example less than 5% by weight.  
       [0035] The structuring of the liquid fatty phase can be modified depending on the nature of the polymer and of the film-forming silicone resin used in the gelling system, and can be such that a rigid structure in the form of a wand or stick, with good mechanical resistance, is obtained. These wands, when they are colored, make it possible, after application, to obtain a glossy, non-migrating deposit with good staying power, especially of the color, over time. The composition can contain one or more structuring polymers and one or more film-forming silicone resins.  
       [0036] The composition of the invention advantageously is a composition for the lips and better a lipstick composition especially in stick form.  
       [0037] Liquid Fatty Phase  
       [0038] According to the invention, the liquid fatty phase comprises at least one silicone oil which can be a volatile oil, a nonvolatile oil or a mixture of volatile oil(s) and nonvolatile oil(s).  
       [0039] An oil is a non-aqueous compound immiscible in water.  
       [0040] The liquid fatty phase preferably comprises at least one volatile silicone oil.  
       [0041] According to the invention, the volatile silicone oil can be chosen from among the linear or cyclic silicone oils having a flash point equal to or in excess of 40° C. and advantageously in excess of the softening point of the polymer of the gelling system and/or a viscosity less than 8 cSt, such as the linear or cyclic polydimethylsiloxanes (PDMS) having from 3 to 7 silicon atoms.  
       [0042] The flash point is the temperature at which a fuel ignites on contact with a flame.  
       [0043] As examples of such oils, there may be cited the compounds mentioned in Table 1 below.  
       [0044] The volatile oil advantageously has a flash point in excess of 60° C.  
       [0045] The nonvolatile silicone oils can be polydimethylsiloxanes, polyalkylmethylsiloxanes, dimethicone copolyols, alkylmethicone copolyols, cetyldimethicone, silicones with alkylglyceryl ether groups, silicones with side amine groups and dilauroyltrimethylol propane siloxysilicate. The alkyl groups of these oils have in particular from 2 to 24 carbon atoms.  
       [0046] The non-volatile silicone oils which can be used in the invention can be, in particular, non-volatile linear polydimethylsiloxanes (PDMS) liquid at room temperature; polydimethylsiloxanes containing alkyl, alcoxy or phenyl groups, pendent and/or at the end of the silicone chain, groups each having from 2 to 24 carbon atoms; phenylated silicones such as the phenyl trimethicones, the phenyl dimethicones, the phenyl trimethylsiloxy diphenylsiloxanes, the diphenyl dimethicones, the diphenyl methyldiphenyl trisiloxanes, the 2-phenylethyl trimethylsiloxysilicates, the fluorous silicones with pendent or end-chain group(s) having from 1 to 12 carbon atoms in which all or part of the hydrogen atoms are substituted with fluorine atoms, the dimethiconols and mixtures thereof.  
       [0047] According to the invention, the liquid fatty phase can comprise at least one volatile silicone oil and at least one volatile non-silicone oil.  
       [0048] In the meaning of the invention, a volatile silicone or non-silicone oil preferably has a flash point of 40 to 135° C. or no flash point. At room temperature (25° C.) and atmospheric pressure (760 mmHg), the volatile oils have a vapor pressure ranging from 0.02 mm to 300 mmHg (2.66 Pa to 40,000 Pa), and better ranging from 0.1 to 90 mmHg (13 Pa to 12,000 Pa). The non-volatile oils then correspond to a vapor pressure less than 0.02 mmHg (2.66 Pa).  
       [0049] The silicone oils of the invention have a viscosity advantageously chosen in the range from 5 to 800,000 cSt at 25° C., preferably from 10 to 500,000 cSt, and better from 10 to 5,000 cSt.  
                               TABLE 1                                       Flash point   viscosity           Compound   (° C.)   (cSt)                                                        Octyltrimethicone   93   1.2           Hexyltrimethicone   79   1.2           Decamethyl   72   4.2           cyclopentasiloxane           (cyclopentasiloxane or D5)           Octamethylcyclo   55   2.5           tetrasiloxane           (cyclotetradimethyl           siloxane or D4)           Dodecamethylcyclo   93   7           hexasiloxane (D6)           Decamethyltetrasiloxane   63   1.7           (L4)           KF 96 A from Shin Etsu   94   6           PDMS   56   1.5           (polydimethylsiloxane)           DC 200 (1.5 cSt)           from Dow Corning           PDMS DC 200 (2 cSt) from   87   2           Dow Corning           PDMS DC 200 (5 cSt) from   134   5 cSt           Dow Corning           PDMS DC 200 (3 cSt) from   102   3 cSt           Dow Corning                      
 
       [0050] In other words, the volatile silicone oil(s) may be chosen, for example, from within the group composed of the compounds of Table 1, heptamethyloctyltrisiloxane, dodecamethylpentasiloxane and mixtures thereof.  
       [0051] The volatile silicone oil also can be chosen from within the group of fluorous silicone oils such as the silicones with alkyl and perfluoralkyl groups, the silicones with oxyethylene/oxypropylene (OE/PP) side groups and perfluorous groups, the silicones with perfluorous side groups and glycerol side groups, and the perfluoroalkylmethylphenylsiloxanes, these oils having a vapor pressure in excess of or equal to 0.02 mmHg.  
       [0052] According to the invention, the liquid fatty phase can contain one or more volatile or nonvolatile non-silicone oils. The volatile non-silicone oils can be chosen from within the group of hydrocarbon oils and volatile esters and ethers such as the volatile hydrocarbons like isododecane and isohexadecane, the C 8 -C 16  isoparaffins, the isohexyl or isodecyl neopentanoates.  
       [0053] The volatile non-silicone oil also may be chosen from among the fluorous oils such as the perfluoropolyethers, the perfluoroalkanes such as perfluorodecaline, the perfluorodamantanes, the monoesters, diesters and triesters of perfluoroalkyl-phosphates and the fluorous ester oils.  
       [0054] As examples of volatile non-silicone oils which can be used in the invention, there may be cited the compounds of Table 2 which follows.  
                           TABLE 2                                       Flash point           Compound   (° C.)                                                    Isododecane   43           Isohexadecane   102           Isodecyl neopentanoate   118           propylene glycol n-butylether   60           3-ethyl ethoxypropionate   58           Propylene glycol methylether acetate*   46           Isopar L (C 11 —C 13  isoparaffin)   62           Isopar H (C 11 —C 12  isoparaffin)   56                      
 
       [0055] The liquid fatty phase advantageously contains at least 30% and better still at least 40% by weight of silicone oil(s) advantageously having a viscosity of less than 1,000 cSt and better less than 100 cSt, because the silicone polymers used in the invention are more soluble in the low-viscosity silicone oils. It also can contain other oils or a mixture of non-silicone oils.  
       [0056] When the fatty phase comprises a volatile oil, the latter advantageously represents from 3 to 89.4%, and better from 5 to 60%, for example from 5 to 10% of the total weight of the composition.  
       [0057] The liquid fatty phase also can contain other non-silicone oils, for example polar oils such as:  
       [0058] the hydrocarbon vegetable oils with a high triglyceride content composed of esters of fatty acids and glycerol, the fatty acids of which can have varying chain lengths, the latter being able to be linear or branched, saturated or unsaturated; these oils are in particular wheat germ oil, corn oil, sunflower oil, karite butter, castor oil, sweet almond oil, macadamia oil, apricot oil, soybean oil, rape oil, cotton oil, alfalfa oil, poppy oil, pumpkin oil, sesame oil, marrow oil, avocado oil, hazelnut oil, grapeseed or blackcurrant seed oil, evening primrose oil, millet oil, barley oil, quinoa oil, olive oil, rye oil, safflower oil, candlenut oil, passion flower oil musk rose oil; or else caprylic/capric acid triglycerides such as those sold by the company Stearines Dubois or those sold under the names Miglyol 810, 812 and 818 by the company Dynamit Nobel;  
       [0059] the synthetic oils or esters of formula R 5 COOR 6  in which R 5  represents the residue of a linear or branched higher fatty acid containing from 1 to 40 and better from 7 to 19 carbon atoms and R 6  represents a branched hydrocarbon chain containing from 1 to 40 and better from 3 to 20 carbon atoms, with R 5 +R 6 ≧10, such as, for example, purcellin oil (cetostearyl octanoate), isononyl isononanoate, C 12  to C 15  alkyl benzoate, isopropyl myristate, 2-ethylhexyl palmitate, alkyl or polyalkyl octanoates, decanoates or ricineolates; hydroxylated esters such as isostearyl lactate, diisostearyl malate; and pentaerythritol esters;  
       [0060] synthetic ethers having from 10 to 40 carbon atoms;  
       [0061] C 8  to C 26  fatty alcohols such as oleic alcohol or octyldodecanol;  
       [0062] fatty acids such as oleic acid, linoleic acid or linolenic acid; and  
       [0063] mixtures thereof.  
       [0064] The liquid fatty phase also can contain apolar oils such as linear or branched hydrocarbons or fluorocarbons of synthetic or mineral origin, volatile or nonvolatile, such as volatile paraffin oils (such as isoparaffins, isododecane) or nonvolatile paraffin oils and derivatives thereof, vaseline, polydecanes, hydrogenated polyisobutene such as parleam, squalane, and mixtures thereof.  
       [0065] Thus the invention can be implemented, for example, with the following different fatty phases:  
       [0066] 1) a fatty phase consisting of a mixture of oils comprising at least one nonvolatile silicone oil and at least one volatile silicone oil;  
       [0067] 2) a fatty phase consisting of a mixture of oils comprising at least one nonvolatile silicone oil and at least one volatile non-silicone oil;  
       [0068] 3) a fatty phase consisting of a mixture of oils comprising at least one nonvolatile silicone oil, at least one volatile silicone oil and at least one volatile non-silicone oil;  
       [0069] 4) a fatty phase consisting of a mixture of oils comprising at least one volatile silicone oil, one nonvolatile non-silicone oil and possibly at least one volatile non-silicone oil, and  
       [0070] 5) a fatty phase consisting solely of volatile silicone oil(s).  
       [0071] In cases 1), 2) and 3), the mixture also can comprise a nonvolatile non-silicone oil.  
       [0072] The liquid fatty phase generally represents from 5 to 99% of the total weight of the composition, and better from 20 to 75%.  
       [0073] Solid Particles  
       [0074] According to the invention, the composition generally furthermore comprises solid particles chosen from among fillers and pigments (including nacreous pigments), and mixtures thereof.  
       [0075] Generally the average size of the solid particles is from 10 nm to 50 μm, and better from 50 nm to 30 μm, for example from 100 nm to 10 μm.  
       [0076] The fillers used in cosmetic compositions generally have the purpose of absorbing sweat and sebum and/or imparting a matte appearance. According to the invention, they furthermore make it possible to structure the liquid fatty phase comprising a silicone oil and to intensify the properties of staying power and/or non-transfer of the composition as well as the thermal stability.  
       [0077] By pigments is understood any solid particle insoluble in the composition serving to impart and/or to modify a color and/or an iridescent appearance.  
       [0078] These pigments can ensure both the function of absorption of sweat and sebum, and the function of coloring or of modification of the appearance of the composition, that is, of the makeup and/or care cosmetic product. In the invention, they also ensure the structuring of the liquid fatty phase.  
       [0079] These fillers or pigments can be of either hydrophobic or hydrophilic nature. When these fillers or pigments are hydrophilic particles, their dispersion in the composition is facilitated either by coating them in a film of hydrophobic compound or by adding a dispersant, and in particular a silicone amphiphilic with respect to the composition.  
       [0080] The hydrophobic pigments or fillers, can be composed of hydrophobic polymer or copolymer powders. As examples of hydrophobic polymers and copolymers used as fillers, there may be cited:  
       [0081] 1) fluorous polymers such as polytetrafluoroethylene powders and powders of tetrafluoroethylene and olefin copolymer, for example of ethylene or propylene; 2) silicone elastomers, for example polymethylsilsesquioxane powders (Tospearl® from Toshiba); 3) polyolefins such as polyethylene; 4) alkyl polymethacrylates, for example methyl polymethacrylate; 5) polyamides (Nylon®); 6) polystyrenes; 7) polyesters and derivatives thereof; 8) polyacrylics (Polytrap® from Dow Corning) or methyl polymethacrylate; and 9) polyurethanes, for example powders of Hexamethylene Diisocyanate/trimethylol hexalactone.  
       [0082] There also can be used hydrophilic fillers treated on the surface so as to be hydrophobic, such as boron nitride, starch, precipitated calcium carbonate, silica, glass or a ceramic.  
       [0083] Instead of powders, there of course can be used fibers of a hydrophobic nature, in particular fibers of the polymers and copolymers cited previously.  
       [0084] The solid particles also can be composed of pigments and/or nacres making it possible to obtain a covering makeup, that is, not allowing the skin, lips or phaneric structures to show through. These particles furthermore make it possible to reduce the sticky feel of the compositions.  
       [0085] The pigments can be white or colored, organic and/or inorganic, coated or uncoated. The inorganic pigments can be chosen, for example, from among the zinc oxides, iron oxides, titanium oxides and mixtures thereof. Thus among the inorganic pigments, there may be cited titanium or zinc dioxide, possibly surface-treated, zirconium or cerium oxides, as well as iron or chromium oxides, manganese violet, ultramarine blue, chromium hydrate and ferric blue. Among the organic pigments there may be cited carbon black, pigments of the D &amp; C type, and the lakes based on cochineal carmine, on barium, strontium, calcium, aluminum. The pigments can represent from 0.1 to 50%, preferably from 0.5 to 40% and better from 2 to 30% of the total weight of the composition, if they are present.  
       [0086] The nacreous pigments (or nacres) can be chosen from among the white nacres such as mica coated with titanium or with bismuth oxychloride, colored nacreous pigments such as titanium mica with iron oxides, titanium mica with, in particular, ferric blue or chromium oxide, titanium mica with an organic pigment of the type mentioned above, as well as nacreous pigments based on bismuth oxychloride. The nacreous pigments also can have gogniochromatic properties and exist in the form of liquid crystals or multilayered plaques. They can represent from 0 to 30%, preferably from 0.1 to 20% of the total weight of the composition, and better from 0.1 to 15%.  
       [0087] When the pigments or the fillers are hydrophilic, they are coated in a film of hydrophobic compound with a view to introducing them into the liquid fatty phase of the composition of the invention.  
       [0088] The coating can be a fluorous coating such as a perfluoroalkyl mono- or diester of phosphoric acid (acid or salt), a perfluoropolyether, a carboxylic or sulfonic perfluoroacid, or a salt of diethanolamine perfluoroalkyl phosphate.  
       [0089] The coating can be a coating based on fluorous silicone, for example a coating-grafting with a silane with a perfluoroalkyl group.  
       [0090] The coating also can be implemented by means of silicone derivatives, for example a coating-grafting with reactive silicones initially possessing hydrogenosilane groups, a coating grafting with a diorganosilane such as dimethylchlorosilane or with an alkylalcoxysilane, a coating-grafting with a silane with a glycydoxypropyl group, a coating with a polyglycerol silicone , or a coating with a silicone or silicone-g-polyacrylic grafted acrylic copolymer.  
       [0091] There also can be used a coating with N-acylamino acids, for example N-lauroyllysine, coatings with fatty acids or fatty acid salts of the stearic acid type, coatings with lecithins and coatings with ester oils.  
       [0092] Dispersion of the hydrophilic particles also may be facilitated by means of at least one amphiphilic silicone which serves as a surfactant between the hydrophilic particles and the hydrophobic silicone phase.  
       [0093] These amphiphilic silicones contain a silicone portion which is compatible with the highly silicone medium of the compositions of the invention, and a hydrophilic portion which can be, for example, the residue of a compound chosen from among the alcohols and the polyols, having from 1 to 12 hydroxyl groups, the polyoxyalkylenes containing at least two oxyalkylene moieties and having from 0 to 20 oxypropylene moieties and/or from 0 to 20 oxyethylene moieties. This hydrophilic portion therefore has an affinity for the hydrophilic particles and contributes to the dispersion thereof in the silicone medium.  
       [0094] The amphilic silicone can be an oil without gelling activity. Such oils can be composed of:  
       [0095] dimethicone copolyols, possibly containing phenyl groups,  
       [0096] alkylmethicone copolyols,  
       [0097] polyglycerol silicones, that is, silicones with alkylglyceryl ether groups,  
       [0098] silicones with perfluorous side groups and with glycerol side groups,  
       [0099] silicones with polyoxyethylene/polyoxypropylene side groups and with perfluorous side groups,  
       [0100] silicone block and hydrophilic block copolymers other than polyether, for example polyoxazoline or polyethyleneimine,  
       [0101] grafted copolymers of the silicone grafted polysaccharide type,  
       [0102] silicone block, poly(ethylene oxide/propylene oxide) block copolymers.  
       [0103] The amphiphilic silicone used in the invention also can be an at least partially crosslinked amphiphilic silicone resin.  
       [0104] As examples of such resins, there can be cited:  
       [0105] crosslinked silicon resins with alkylpolyether groups, such as ethylene polyoxide (POE) and ethylene polyoxide/propylene polyoxide (POE/POP), described in U.S. Pat. No. 5,412,004 [9], and  
       [0106] silicone resins crosslinked in part with α,ω-dienes, possessing both hydrophilic POE/POP side chains and hydrophobic alkyl side chains such as those described in EP-A-1 048 686 [10]. The hydrophilic side chains are obtained by reaction with a POE/POP at a single vinyl end, and the alkyl side chains are formed by reaction with an α-olefin with a fatty chain.  
       [0107] In the amphiphilic silicone resin, the silicone portion advantageously is made up of polydimethylsiloxane.  
       [0108] Gelling Silicone Polymer  
       [0109] The polymer or polymers structuring or gelling the composition is/are solid at room temperature (25° C.) and atmospheric pressure (760 mmHg) and soluble in the liquid fatty phase at a temperature of 25 to 250° C.  
       [0110] In the meaning of the invention, there is understood by polymer a compound having at least 2 repeating moieties, preferably at least 3 repeating moieties, and better still 10 repeating moieties.  
       [0111] In the composition of the invention, the silicone polymer of the gelling system represents generally from 0.5 to 80%, preferably from 2 to 60%, and better still from 5 to 40% of the total weight of the composition.  
       [0112] Furthermore, the gelling-system polymer/silicone oil(s) mass ratio is preferably from 0.1 to 50%.  
       [0113] The polymers used as gelling agents in the composition of the invention are polymers of the polyorganosiloxane type such as those described in the documents U.S. Pat. No. 5,874,069 [3], U.S. Pat. No. 5,919,441 [4], U.S. Pat. No. 6,051,216 [5] and U.S. Pat. No. 5,981,680 [11].  
       [0114] According to the invention, the polymers used as a gelling agent can belong to the following two families:  
       [0115] 1) polyorganosiloxanes comprising at least two groups capable of establishing hydrogen interactions, these two groups being located in the polymer chain; and/or  
       [0116] 2) polyorganosiloxanes comprising at least two groups capable of establishing hydrogen interactions, these two groups being located on grafts or branches.  
       [0117] The polymers to which the invention applies are solids that can be dissolved beforehand in a solvent with hydrogen interaction capable of breaking the hydrogen interactions of the polymers, such as the C 2  to C 8  lower alcohols and in particular ethanol, n-propanol, isopropanol, before being placed in the presence of the silicone oils according to the invention. It also is possible to use these hydrogen interaction “breaking” solvents as cosolvent. These solvents then can be kept in the composition or else be removed by selection evaporation, well known to the person skilled in the art.  
       [0118] The polymers comprising two groups capable of establishing hydrogen interactions in the polymer chain can be polymers comprising at least one moiety corresponding to the formula:  
                 
 
       [0119] in which:

       [0130] 5) the groups G, identical or different, represent divalent groups chosen from among:  
                 
 
       [0131] in which R 6  represents a hydrogen atom or a linear or branched C 1  to C 20  alkyl group, on condition that at least 50% of the groups R 6  of the polymer represents a hydrogen atom and that at least two of the groups G of the polymer are a group other than:  
                 
 
       [0132] 6) n is an integer ranging from 2 to 500, preferably from 2 to 200, and m is an integer ranging from 1 to 1000, preferably from 1 to 700, and better still from 6 to 200.  
       [0133] According to the invention, 80% of the groups R 1 , R 2 , R 3  and R 4  of the polymer preferably are chosen from among the methyl, ethyl, phenyl and 3,3,3-trifluoropropyl groups.  
       [0134] According to the invention, Y can represent various divalent groups, possibly furthermore comprising one or two free valences to establish bonds with other moieties of the polymer or copolymer. Preferably Y represents a group chosen from among:  
       [0135] a) linear C 1  to C 20 , preferably C 1  to C 10 , alkylene groups,  
       [0136] b) C 30  to C 56  branched alkylene groups which can comprise rings and unconjugated unsaturations,  
       [0137] c) C 5 -C 6  cycloalkylene groups,  
       [0138] d) phenylene groups possibly substituted with one or more C 1  to C 40  alkyl groups,  
       [0139] e) C 1  to C 20  alkylene groups, comprising from 1 to 5 amide groups,  
       [0140] f) C 1  to C 20  alkylene groups comprising one or more substituents chosen from among the hydroxyl, C 3  to C 8  cycloalkane, C 1  to C 3  hydroxyalkyl and C 1  to C 6  alkylamine groups,  
       [0141] g) polyorganosiloxane chains of formula:  
                 
 
       [0142] in which R 1 , R 2  R 3 , R 4 , T and m are such as defined hereinabove, and  
       [0143] h) polyorganosiloxane chains of formula:  
                 
 
       [0144] The polyorganosiloxanes of the second family can be polymers comprising at least one moiety corresponding to formula (II):  
                 
 
       [0145] in which  
       [0146] R 1  and R 3 , identical or different, are such as defined hereinabove for formula (I),  
       [0147] R 7  represents a group such as defined hereinabove for R 1  and R 3 , or represents the group of formula —X-G-R 9  in which X and G are such as defined hereinabove for formula (I) and R 9  represents a hydrogen atom or a linear, branched or cyclic, saturated or unsaturated, C 1  to C 50  hydrocarbon group, possibly comprising in its chain one or more atoms chosen from among O, S and N, possibly substituted with one or more fluorine atoms and/or one or more hydroxyl groups, or a phenyl group possibly substituted with one or more C 1  to C 4  alkyl groups.  
       [0148] R 8  represents the group of formula —X-G-R 9  in which X, G and R 9  are such as defined hereinabove,  
       [0149] m 1  is an integer ranging from 1 to 998, and  
       [0150] m 2  is an integer ranging from 2 to 500.  
       [0151] According to the invention, the polymer used as a gelling agent can be a homopolymer, that is, a polymer comprising several identical moieties, in particular moieties of formula (I) or of formula (II).  
       [0152] According to the invention, there also may be used a polymer consisting of a copolymer comprising several different moieties of formula (I), that is, a polymer in which at least one of the groups R 1 , R 2 , R 3 , R 4 , X, G, Y, m and n is different in one of the moieties. The copolymer also can be made up of several moieties of formula (II), in which at least one of the groups R 1 , R 3 , R 7 , R 8 , m 1  and m 2  is different in at least one of the moieties.  
       [0153] There also may be used a copolymer comprising at least one moiety of formula (I) and at least one moiety of formula (II), the moieties of formula (I) and the moieties of formula (II) being able to be identical or different from one another.  
       [0154] According to a variant of the invention, there also may be used a copolymer furthermore containing at least one hydrocarbon moiety comprising two groups capable of establishing hydrogen interactions, chosen from among the ester, amide, sulfonamide, carbamate, thiocarbamate, urea, thiourea, oxamido, guanidino, biguanidino groups and combinations thereof.  
       [0155] These copolymers may be block copolymers, sequenced copolymers or grafted copolymers.  
       [0156] According to a first embodiment of the invention, the groups capable of establishing hydrogen interactions are amide groups of formula —C(O)NH— and —HN—C(O)—.  
       [0157] In this case, the gelling agent can be a polymer comprising at least one moiety of formula (III) or (IV):  
                 
 
       [0158] in which R 1 , R 2 , R 3 , R 4 , X, Y, m and n are such as defined hereinabove.  
       [0159] Such a moiety can be obtained:  
       [0160] either by a condensation reaction between a silicone with α,ω-carboxylic acid ends and one or more diamines, according to the following reaction diagram:  
                 
 
       [0161] or by reaction of two molecules of α-unsaturated carboxylic acid with a diamine according to the following reaction diagram:  
                 
 
       [0162] followed by the addition of a siloxane to the ethylene unsaturations, according to the following diagram:  
                 
 
       [0163] in which X 1 —(CH 2 ) 2 — corresponds to X defined hereinabove and Y, R 1 , R 2 , R 3 , R 4  and m are such as defined hereinabove;  
       [0164] or by reaction of a silicone with α,ω-NH 2  ends and a diacid of formula HOOC—Y—COOH according to the following reaction diagram:  
                 
 
       [0165] In these polyamides of formula (III) or (IV), m is preferably in the range from 1 to 700, preferably from 15 to 500 and better still from 15 to 45, and n in particular is in the range from 1 to 500, preferably from 1 to 100 and better still from 4 to 25,  
       [0166] X is preferably a linear or branched alkylene chain having 1 to 30 carbon atoms, in particular 3 to 10 carbon atoms, and  
       [0167] Y is preferably an alkylene chain that is linear or branched or that can comprise rings and/or unsaturations, having from 1 to 40 carbon atoms, in particular from 1 to 20 carbon atoms, and better still from 2 to 6 carbon atoms, in particular 6 carbon atoms.  
       [0168] In formulas (III) and (IV), the alkylene group representing X or Y possibly can contain at least one of the following elements in its alkylene portion:  
       [0169] 1) 1 to 5 amide, urea or carbamate groups,  
       [0170] 2) a C 5  or C 6  cycloalkyl group, and  
       [0171] 3) a phenylene group possibly substituted with 1 to 3 identical or different C 1  to C 3  alkyl groups.  
       [0172] In formulas (III) and (IV), the alkylene groups also may be substituted with at least one element chosen from within the group consisting of:  
       [0173] a hydroxy group,  
       [0174] a C 3  to C 8  cycloalkyl group,  
       [0175] one to three C 1  to C 40  alkyl groups,  
       [0176] a phenyl group possibly substituted with one to three C 1  to C 3  alkyl groups,  
       [0177] a C 1  to C 3  hydroxyalkyl group, and  
       [0178] a C 1  to C 6  aminoalkyl group.  
       [0179] In these formulas (III) and (IV), Y also can represent:  
                 
 
       [0180] in which R 5  represents a polyorganosiloxane chain, and T represents a group of formula:  
                 
 
       [0181] in which a, b and c are, independently, integers ranging from 1 to 10, and R 10  is a hydrogen atom or a group such as those defined for R 1 , R 2 , R 3  and R 4 .  
       [0182] In formulas (III) and (IV), R 1 , R 2 , R 3  and R 4  preferably represent, independently, a linear or branched C 1  to C 40  alkyl group, preferably a CH 3 , C 2 H 5 , n-C 3 H 7  or isopropyl group, a polyorganosiloxane chain or a phenyl group possibly substituted with one to three methyl or ethyl groups.  
       [0183] As has been seen previously, the polymer can comprise identical or different moieties of formula (III) or (IV).  
       [0184] Thus the polymer can be a polyamide containing several moieties of formula (III) or (IV) of different lengths, that is, a polyamide corresponding to the formula:  
                 
 
       [0185] in which X, Y, n, R 1  to R 4  have the meanings given hereinabove, m 1  and m 2 , which are different, are chosen from within the range from 1 to 1000, and p is an integer ranging from 2 to 300.  
       [0186] In this formula, the moieties can be structured to form either a block copolymer, or a random copolymer or an alternating copolymer. In this copolymer, the moieties can be not only of different lengths, but also of different chemical structures, for example having different groups Y. In this case, the copolymer can correspond to the formula:  
                 
 
       [0187] in which R 1  to R 4 , X, Y, m 1 , m 2 , n and p have the meanings given hereinabove and Y 1  is different from Y but chosen from among the groups defined for Y. As previously, the various moieties can be structured to form either a block copolymer, or a random copolymer or an alternating copolymer.  
       [0188] In this first embodiment of the invention, the gelling agent also can consist of a grafted copolymer. Thus the polyamide with silicone units can be grafted and possibly crosslinked with silicone chains having amide groups. Such polymers can be synthesized with trifunctional amines.  
       [0189] In this case, the copolymer can comprise at least one moiety of formula:  
                 
 
       [0190] in which X 1  and X 2 , which are identical or different, have the meaning given for X in formula (I), n is such as defined in formula (I), Y and T are such as defined in formula (I), R 11  to R 18  are groups chosen from within the same group as R 1  to R 4 , m 1  and m 2  are numbers falling in the range from 1 to 1000, and p is an integer ranging from 2 to 500.  
       [0191] In formula (VII), it is preferred that:  
       [0192] p is in the range of 1 to 25, better still from 1 to 7,  
       [0193] R 11  to R 18  are methyl groups,  
       [0194] T corresponds to one of the following formulas:  
                 
 
       [0195] in which R 19  is a hydrogen atom or a group chosen from among the groups defined for R 1  to R 4 , and R 20 , R 21  and R 22  are, independently, linear or branched alkylene groups, and preferably still, with the formula:  
                 
 
       [0196] in particular with R 20 , R 21 , and R 22  representing —CH 2 —CH 2 —,  
       [0197] m 1  and m 2  are in the range from 15 to 500, and better still from 15 to 45,  
       [0198] X 1  and X 2  represent —(CH 2 ) 10 —, and  
       [0199] Y represents —CH 2 —.  
       [0200] These polyamides with a grafted silicone moiety of formula (VII) can be copolymerized with polyamide-silicones of formula II to form block copolymers, alternating copolymers or random copolymers. The weight percentage of grafted silicone moieties (VII) in the copolymer can range from 0.5% to 30% by weight.  
       [0201] According to the invention, as has been seen previously, the siloxane units can be in the main chain or backbone of the polymer, but they also can be present in grafted or pendent chains. In the main chain, the siloxane units can be in the form of segments as described hereinabove. In the pendent or grafted chains, the siloxane units can appear individually or in segments.  
       [0202] According to the invention, the preferred siloxane-based polyamides are:  
       [0203] polyamides of formula (III) in which m is from 15 to 50;  
       [0204] mixtures of two or more polyamides in which at least one polyamide has a value of m in the range from 15 to 50 and at least one polyamide has a value of m in the range from 30 to 50;  
       [0205] polymers of formula (V) with m 1  chosen from within the range of 15 to 50 and m 2  chosen from within the range of 30 to 500 with the portion corresponding to m 1  representing 1 to 99% by weight of the total weight of the polyamide and the portion corresponding to m 2  representing 1 to 99% by weight of the total weight of the polyamide;  
       [0206] mixtures of polyamide of formula (III) combining  
       [0207] 1) 80 to 99% by weight of a polyamide in which n is equal to 2 to 10, in particular 3 to 6, and  
       [0208] 2) 1 to 20% of a polyamide in which n is in the range from 5 to 500, in particular from 6 to 100;  
       [0209] polyamides corresponding to formula (VI) in which at least one of the groups Y and Y 1  contains at least one hydroxyl substituent;  
       [0210] polyamides of formula (III) synthesized with at least one portion of an activated diacid (diacid chloride, dianhydride or diester) instead of the diacid;  
       [0211] polyamides of formula (III) in which X represents —(CH 2 ) 3 — or —(CH 2 ) 10 ; and  
       [0212] polyamides of formula (III) in which the polyamides are terminated with a monofunctional chain chosen from within the group consisting of monofunctional amines, monofunctional acids, monofunctional alcohols, including fatty acids, fatty alcohols, and fatty amines, such as, for example, octylamine, octanol, stearic acid and stearyl alcohol.  
       [0213] According to the invention, the ends of the polymer chains can be terminated with:  
       [0214] a C 1  to C 50  alkyl ester group by introducing a C 1  to C 50  monoalcohol during synthesis,  
       [0215] a C 1  to C 50  alkylamide group by taking as stopping group a monoacid if the silicone is α,ω-diaminated, or a monoamine if the silicone is an α,ω-dicarboxylic acid.  
       [0216] According to one embodiment variant of the invention, there can be used a copolymer of silicone polyamide and of hydrocarbon polyamide, that is, a copolymer comprising moieties of formula (III) or (IV) and hydrocarbon polyamide moieties. In this case, the polyamide-silicone moieties can be arranged at the ends of the hydrocarbon polyamide.  
       [0217] Polyamide-based gelling agents containing silicones can be produced by silylic amidation of polyamides based on fatty acid dimer. This approach involves the reaction of free acid sites existing on a polyamide as end sites, with oligosiloxane-monoamines and/or oligosiloxane-diamines (amidation reaction), or alternatively with oligosiloxane alcohols or oligosiloxane diols (esterification reaction). The esterification reaction requires the presence of acid catalysts, as is known in the art. It is desirable for the polyamide having free acid sites, used for the amidation or esterification reaction, to have a relatively high number of acid end groups (for example, polyamides having high acid values, for example from 15 to 20).  
       [0218] For the amidation of the free acid sites of the hydrocarbon polyamides, siloxane diamines with 1 to 300, more particularly 2 to 50, and better still 2, 6, 9.5, 12, 13.5, 23 or 31 siloxane groups, can be used for the reaction with hydrocarbon diamides based on fatty acid dimers. Siloxane diamines having 13.5 siloxane groups are preferred, and the best results are obtained with the siloxane-diamine having 13.5 siloxane groups and polyamides containing high values for carboxylic acid end groups.  
       [0219] The reactions may be carried out in xylene to extract the water produced from the solution by azeotropic distillation, or at higher temperatures (about 180 to 200° C.) without solvent. Typically, the efficacy of the amidation and the reaction rates decrease when the siloxane diamine is longer, that is, when the number of siloxane groups is higher. Free amine sites can be blocked after the initial amidation reaction of the diaminosiloxanes by reacting them either with an acid siloxane or with an organic acid such as benzoic acid.  
       [0220] For the esterification of the free acid sites on the polyamides, this can be performed in boiling xylene with about 1% by weight, relative to the total weight of the reagents, of para-toluenesulfonic acid as catalyst.  
       [0221] These reactions carried out on the carboxylic acid end groups of the polyamide lead to the incorporation of silicone moieties only at the ends of the polymer chain.  
       [0222] A polyamide-silicone copolymer also can be prepared using a polyamide with free amine groups, by amidation reaction with a siloxane containing an acid group.  
       [0223] There also can be prepared a gelling agent based on a copolymer between a hydrocarbon polyamide and a silicone polyamide, by transamidation of a polyamide having, for example, an ethylene-diamine constituent, with an oligosiloxane-α,ω-diamine, at high temperature (for example 200 to 300° C.), in order to carry out a transamidation such that the ethylenediamine component of the original polyamide is replaced with the oligosiloxane diamine.  
       [0224] The copolymer of hydrocarbon polyamide and of polyamide-silicone also can be a grafted copolymer comprising a hydrocarbon polyamide backbone with pendent oligosiloxane groups.  
       [0225] This can be obtained, for example:  
       [0226] by hydrosilylation of unsaturated bonds in polyamides based on fatty acid dimers;  
       [0227] by silylation of the amide groups of a polyamide; or  
       [0228] by silylation of unsaturated polyamides by means of an oxidation, that is, by oxidizing the unsaturated groups into alcohols or diols, in order to form hydroxyl groups which are reacted with siloxane carboxylic acids or siloxane alcohols. The olefinic sites of the unsaturated polyamides also can be epoxidized and the epoxy groups then can be reacted with siloxane amines or siloxane alcohols.  
       [0229] According to a second embodiment of the invention, the gelling agent consists of a homopolymer or a copolymer comprising urethane or urea groups.  
       [0230] As previously, the polymer can comprise polyorganosiloxane moieties containing two or more urethane and/or urea groups, either in the backbone of the polymer, or on side chains or as pendent groups.  
       [0231] The polymers comprising at least two urethane and/or urea groups in the backbone may be polymers comprising at least one moiety corresponding to the following formula:  
                 
 
       [0232] in which R 1 , R 2 , R 3 , R 4 , X, Y, m and n have the meanings given hereinabove for formula (I), and U represents —O— or —NH—, so that:  
                 
 
       [0233] corresponds to a urethane or urea group.  
       [0234] In this formula (VIII), Y can be a linear or branched C 1  to C 40  alkylene group, possibly substituted with a C 1  to C 15  alkyl group or a C 5  to C 10  aryl group. Preferably a —(CH 2 ) 6 — group is used.  
       [0235] Y also can represent a C 5  to C 12  cycloaliphatic or aromatic group which can be substituted with a C 1  to C 15  alkyl group or a C 5  to C 10  aryl group, for example a radical chosen from among the methylene-4-4-bicyclohexyl radical, the radical derived from isophorone diisocyanate, 2,4- and 2,6 tolylenes, 1,5 naphthylene, p-phenylene and 4, 4′-biphenylenemethane. Generally, it is preferred that Y represent a linear or branched C 1  to C 40  alkylene radical, or a C 4  to C 12  cycloalkylene radical.  
       [0236] Y also can represent a polyurethane or polyurea sequence corresponding to the condensation of several diisocyanate molecules with one or more molecules of coupling agents of the diol or diamine type. In this case, Y comprises several urethane or urea groups in the alkylene chain.  
       [0237] It can correspond to the formula:  
                 
 
       [0238] in which B 1  is a group chosen from among the groups given hereinabove for Y, U is —O— or —NH—, and B 2  is chosen from among:  
       [0239] linear or branched C 1  to C 40  alkylene groups, which possibly can bear an ionizable group such as a carboxylic or sulfonic acid group, or a neutralizable or quaternizable tertiary amine group,  
       [0240] C 5  to C 12  cycloalkylene groups, possibly bearing alkyl, for example one to three methyl or ethyl groups, or alkylene substituents, for example the diol radical: cyclohexanedimethanol,  
       [0241] phenylene groups which possibly can bear C 1  to C 3  alkyl substituents, and  
       [0242] groups of formula:  
                 
 
       [0243] in which T is a hydrocarbon trivalent radical which can contain one or more hetero atoms such as oxygen, sulfur and nitrogen and R 5  is a polyorganosiloxane chain or linear or branched C 1  to C 50  alkyl chain.  
       [0244] T can represent, for example:  
                 
 
       [0245] with w being an integer ranging from 1 to 10 and R 5  being a polyorganosiloxane chain.  
       [0246] When Y is a linear or branched C 1  to C 40  alkylene group, the —(CH 2 ) 2 — and —(CH 2 ) 6 — groups are preferred.  
       [0247] In the formula for Y given hereinabove, d can be an integer ranging from 0 to 5, preferably from 0 to 3, preferably still equal to 1 or 2.  
       [0248] B 2  preferably is a linear or branched C 1  to C 40  alkylene group, in particular —(CH 2 ) 2 — or —(CH 2 ) 6 —, or the group:  
                 
 
       [0249] with R 5  being a polyorganosiloxane chain.  
       [0250] As previously, the polymer constituting the gelling agent can be formed from silicone urethane and/or silicone urea moieties of different length and/or constitution, and be in the form of block, sequenced or statistical (random) copolymers.  
       [0251] According to the invention, the silicone also can comprise urethane and/or urea groups no longer in the backbone but as side branches.  
       [0252] In this case, the polymer can comprise at least one moiety of formula:  
                 
 
       [0253] in which R 1 , R 2 , R 3 , m 1 , and m 2  have the meanings given hereinabove for formula (I),  
       [0254] U represents O or NH,  
       [0255] R 23 represents a C 1  to C 40  alkylene group, possibly comprising one or more hetero atoms chosen from among O and N, or a phenylene group, and  
       [0256] R 24  is chosen from among the linear, branched or cyclic, saturated or unsaturated C 1  to C 50  alkyl groups, and the phenyl groups possibly substituted with one to three C 1  C 3  alkyl groups.  
       [0257] The polymers comprising at least one moiety of formula (X) contain siloxane units and urea or urethane groups, and they can be used as gelling agents in the compositions of the invention.  
       [0258] The siloxane polymers can have a single urea or urethane group by branching or can have branches with two urea or urethane groups, or even contain a mixture of branches with one urea or urethane group and branches with two urea or urethane groups.  
       [0259] They can be obtained from branched polysiloxanes, comprising one or two amino groups by branching, by reacting these polysiloxanes with monoisocyanates.  
       [0260] As examples of starting polymers of this type having amino and diamino branches, there can be cited the polymers corresponding to the following formulas:  
                 
 
       [0261] In these formulas, the symbol “/” indicates that the segments can be of different lengths and in a random order, and R represents a linear aliphatic group preferably having 1 to 6 carbon atoms and better still 1 to 3 carbon atoms.  
       [0262] Such polymers with branching can be formed by reacting a siloxane polymer, having at least three amino groups per polymer molecule, with a compound having only one monofunctional group (for example an acid, an isocyanate or isothiocyanate) in order to react this monofunctional group with one of the amino groups and to form groups capable of establishing hydrogen interactions. The amino groups can be on side chains extending from the main chain of the siloxane polymer, so that the groups capable of establishing hydrogen interactions are formed on these side chains, or else the amino groups can be at the ends of the main chain, so that the groups capable of hydrogen interaction will be end groups of the polymer.  
       [0263] As an operating method for forming a polymer containing siloxane units and groups capable of establishing hydrogen interactions, there may be cited the reaction of a siloxane diamine and a diisocyanate in a silicone solvent so as to provide a gel directly. The reaction can be performed in a silicone fluid, the resulting product being dissolved in the silicone fluid, at high temperature, the temperature of the system then being reduced in order to form the gel.  
       [0264] The polymers preferred for incorporation into the compositions according to this invention are siloxane-urea copolymers which are linear and which contain urea groups as groups capable of establishing hydrogen interactions in the backbone of the polymer.  
       [0265] As an illustration of a polysiloxane ending with four urea groups, there may be cited the polymer of formula:  
                 
 
       [0266] in which Ph is a phenyl group and n is a number from 0 to 300, in particular from 0 to 100, for example 50.  
       [0267] This polymer is obtained by reaction of the following polysiloxane having amino groups:  
                 
 
       [0268] with phenyl isocyanate.  
       [0269] The polymers of formula (VIII) comprising urea or urethane groups in the chain of the silicone polymer can be obtained by reaction between a silicone having α,ω-NH 2  or —OH end groups, of formula:  
                 
 
       [0270] in which m, R 1 , R 2 , R 3 , R 4  and X are such as defined for formula (I), and a diisocyanate OCN—Y—NCO in which Y has the meaning given in formula (I); and possibly a diol or diamine coupling agent of formula H 2 N—B 2 —NH 2  or HO—B 2 —OH, in which B 2  is such as defined in formula (IX).  
       [0271] According to the stoichiometric proportions between the two reagents, diisocyanate and coupling agent, Y can have the formula (IX) with d equal to 0 or d equal to 1 to 5.  
       [0272] As in the case of the silicone polyamides of formula (II) or (III), there may be used in the invention silicone Apolyurethanes or polyureas having moieties of different length and structure, in particular moieties with lengths differing by the number of silicone units. In this case, the copolymer can correspond, for example, to the formula:  
                 
 
       [0273] in which R 1 , R 2 , R 3 , R 4 , X, Y and U are such as defined for formula (VIII) and m 1 , m 2 , n and p are such as defined for formula (V).  
       [0274] Branched silicone polyurethanes or polyureas also may be obtained by using, instead of the diisocyanate OCN—Y—NCO, a triisocyanate of formula:  
                 
 
       [0275] A silicone polyurethane or polyurea having branches comprising an organosiloxane chain with groups capable of establishing hydrogen interactions is obtained in this manner. Such a polymer comprises, for example, a moiety corresponding to the formula:  
                 
 
       [0276] in which X 1  and X 2 , which are identical or different, have the meaning given for X in formula (I), n is such as defined in formula (I), Y and T are such as defined in formula (I), R 11  to R 18  are groups chosen from within the same group as R 1  to R 4 , m 1  and m 2  are numbers falling in the range from 1 to 1000, and p is an integer ranging from 2 to 500.  
       [0277] As in the case of the polyamides, this copolymer also can comprise silicone polyurethane moieties without branching.  
       [0278] In this second embodiment of the invention, the preferred siloxane-based polyureas and polyurethanes are:  
       [0279] polymers of formula (VIII) in which m is from 15 to 50;  
       [0280] mixtures of two or more polymers in which at least one polymer has a value of m in the range from 15 to 50 and at least one polymer has a value of m in the range from 30 to 50;  
       [0281] polymers of formula (VIII) with m 1  chosen from within the range from 15 to 50 and m 2  chosen from within the range from 30 to 500 with the portion corresponding to m 1  representing 1 to 99% by weight of the total weight of the polymer and the portion corresponding to m 2  representing 1 to 99% by weight of the total weight of the polymer;  
       [0282] mixtures of polymer of formula (VIII) combining  
       [0283] 1) 80 to 99% by weight of a polymer in which n is equal to 2 to 10, in particular 3 to 6, and  
       [0284] 2) 1 to 20% of a polymer in which n is in the range from 5 to 500, in particular from 6 to 100,  
       [0285] copolymers comprising two moieties of formula (VIII) in which at least one of the groups Y contains at least one hydroxyl substituent;  
       [0286] polymers of formula (VIII) synthesized with at least one portion of an activated diacid (diacid chloride, dianhydride or diester) instead of the diacid;  
       [0287] polymers of formula (VIII) in which X represents —(CH 2 ) 3 — or —(CH 2 ) 10 —; and  
       [0288] polymers of formula (VIII) in which the polymers are terminated with a monofunctional chain chosen from among the group consisting of monofunctional amines, monofunctional acids, monofunctional alcohols, including fatty acids, fatty alcohols and fatty amines, such as, for example, octylamine, octanol, stearic acid and stearyl acid.  
       [0289] As in the case of the polyamides, copolymers of silicone polyurethane—or polyurea—and of hydrocarbon polyurethane or polyurea can be used in the invention by performing the reaction for synthesizing the polymer in the presence of an α,ω-difunctional sequence of non-silicone nature, for example a polyester, a polyether or a polyolefin.  
       [0290] As has been seen previously, the gelling agents consisting of homopolymers or copolymers of the invention can have siloxane moieties in the main chain of the polymer and groups capable of establishing hydrogen interactions, either in the main chain of the polymer or at the ends thereof, or on side chains or branches of the main chain. This can correspond to the following five arrangements:  
                 
 
       [0291] in which the continuous line is the main chain of the siloxane polymer and the squares represent the groups capable of establishing hydrogen interactions.  
       [0292] In case (1), the groups capable of establishing hydrogen interactions are arranged at the ends of the main chain. In case (2), two groups capable of establishing hydrogen interactions are arranged at each of the ends of the main chain.  
       [0293] In case (3), the groups capable of establishing hydrogen interactions are arranged within the main chain in repeating moieties.  
       [0294] In cases (4) and (5), these are copolymers in which the groups capable of establishing hydrogen interactions are arranged on branches of the main chain of a first series of moieties which are copolymerized with moieties not comprising groups capable of establishing hydrogen interactions. The values n, x and y are such that the polymer has the desired properties as a gelling agent for fatty phases based on silicone oil.  
       [0295] According to the invention, the structuring of the liquid fatty phase containing at least one silicone oil is obtained with the aid of one or more of the polymers mentioned above in combination with one or more film-forming silicone resins.  
       [0296] As examples of polymers which can be used, there may be cited the silicone polymers obtained in accordance with Examples 1 and 2 of document U.S. Pat. No. 5,981,680.  
       [0297] The polymers and copolymers used in the gelling system for the composition of the invention advantageously have a softening point of 65° C. to 190° C. They preferably have a softening point ranging from 70 to 130° C. and better from 80° C. to 105° C. This softening point is lower than that of the known structuring polymers, which facilitates the use of the polymers which are the subject of the invention, makes possible the use of volatile oils and limits the degradation of the liquid fatty phase.  
       [0298] They have good solubility in silicone oils and result in macroscopically homogeneous compositions. They preferably have an average molecular mass from 500 to 200,000, for example from 1,000 to 100,000, preferably from 2,000 to 30,000.  
       [0299] Film-Forming Silicone Resin  
       [0300] The composition according to the invention contains one or more film-forming silicone resins. This or these film-forming silicone resin(s) makes/make it possible to improve the staying power and to obtain all the surprising effects mentioned above.  
       [0301] As a general rule, the word “resin” denotes a three-dimensional structure.  
       [0302] The at least one film-forming silicone resin used in the compositions of the invention can be any silicone resin which has film-forming properties.  
       [0303] In one embodiment, the film-forming silicone resin is chosen from among the silsesquioxanes, the siloxysilicates and the resins obtained by hydroxysililation.  
       [0304] The use of silicone polymers or derivatives thereof as film-forming agents in cosmetic compositions is known in the art: see for example, the patents U.S. Pat. No. 5,965,112, U.S. Pat. No. 5,800,816, U.S. Pat. No. 5,911,974 and U.S. Pat. No. 5,959,009. Nonetheless, the combination of such resins with the special polymers according to the invention is neither described nor suggested in the prior art. Nothing led one to imagine, in consideration of the prior art, that such a combination could result in a surprising improvement in the properties, especially of staying power and possibly of non-transfer, in a deposit obtained from a cosmetic composition comprising this combination.  
       [0305] The nomenclature of the silicone resins is known in the art under the name of “MDTQ” nomenclature, by which a silicone resin is described according to the various repeating siloxane monomer moieties which constitute the polymer.  
       [0306] Each letter of “MDTQ” corresponds to a different type of moiety.  
       [0307] The symbol “M” corresponds to the monofunctional moiety (CH 3 ) 3 SiO 1/2 . This moiety is regarded as monofunctional because the silicon atom shares only one oxygen for the formation of the chain. The “M” moiety can be represented by:  
                 
 
       [0308] At least one of the methyl groups can be replaced so as, for example, to produce a moiety with the formula [R(CH 3 ) 2 ]SiO 1/2 , such as represented by the following structure:  
                 
 
       [0309] in which R is other than a methyl group.  
       [0310] The symbol “D” corresponds to the difunctional moiety (CH 3 ) 2 SiO 2/2  in which two of the available bonds on the silicon atom are used to bond with oxygen for the formation of the polymer chain.  
       [0311] The “D” moiety, which is the essential component element of the dimethicone oils, can be represented by:  
                 
 
       [0312] The symbol “T” corresponds to the trifunctional moiety (CH 3 )SiO 3/2 , in which three of the available bonds on the silicon atom are used to bond with oxygen for the formation of the polymer chain.  
       [0313] The “T” moiety can be represented by:  
                 
 
       [0314] As in the “M” moiety, any one of the methyl groups can be replaced in “D” or “T” by an R group which is other than methyl.  
       [0315] Finally, the symbol “Q” corresponds to a quadrifunctional moiety SiO 4/2 , in which all four available bonds on the silicon atom are used to bond with oxygen for the formation of the polymer chain.  
       [0316] The “Q” moiety can be represented by:  
                 
 
       [0317] The number of different silicones which can be produced is staggering. It is clear to the person skilled in this field of the art that the properties of each of the silicones are going to vary according to the type of monomer, the type of substitution, the size of the polymer chain, and the degree of crosslinking or the size of the side chain. Different properties are obtained depending on whether the backbone (the main chain) is a silicone chain with carbon-based side chains or the backbone is carbon-based with silicone side chains.  
       [0318] As has been described hereinabove, in one embodiment the (at least) one film-forming silicone resin can be chosen from among the siloxysilicates, silsesquioxanes and resins obtained by hydroxysililation. Any siloxysilicate, silsesquioxane or resin obtained by hydroxysililation which acts as a film-forming agent can be used in the composition of the invention. The film-forming silicone resins preferably are crosslinked.  
       [0319] In one embodiment, the film-forming silicone resin is chosen from among the substituted siloxysilicates, silsesquioxanes and resins obtained by hydroxysililation. A substituted siloxysilicate or a substituted silsesquioxane can be, for example, a siloxysilicate or a silsesquioxane in which a methyl group has been replaced by a longer carbon chain, such as an ethane, propane or butane chain. The carbon chain can be saturated or nonsaturated.  
       [0320] In one embodiment, the film-forming silicone resin is chosen from among the siloxysilicates, such as the trimethylsiloxysilicates, which are represented by the following formula:  
       [(CH 3 ) 3 —Si—O] x —(SiO 4/2 ) y  (MQ moieties),  
       [0321] in which x and y can have values ranging from 50 to 80.  
       [0322] In another embodiment, a siloxysilicate can be chosen from among all the combinations of M and of Q moieties such as, for example, [R(R) 3 —Si—O]x-(SiO 4/2 )y, in which R is chosen from among the methyl groups and the longer carbon chains.  
       [0323] In another embodiment, the film-forming silicone resin is chosen from among the silsesquioxanes which are represented by the following formula:  
       (CH 3 SiO 3/2 ) x (T moieties)  
       [0324] in which x has a value which can range up to several thousands and the CH 3  can be replaced by an R, such as described hereinabove for the T moieties.  
       [0325] In one embodiment, the silsesquioxane is chosen from among the polymethylsilsesquioxanes, which are the silsesquioxanes which do not have a substituent replacing the methyl group.  
       [0326] The polymethylsilsesquioxanes useful in this invention are film-forming agents and can comprise, for example, approximately 500 or fewer T moieties, preferably from approximately 50 to approximately 500 T moieties.  
       [0327] In one embodiment of the invention, these film-forming silicone resins are soluble or dispersible in silicones, in particular volatile, or other organic liquids. In one embodiment, the film-forming silicone resin or resins can be solid at approximately 25° C. They preferably exist in crosslinked or three-dimensional form. In one embodiment, the film-forming silicone resin can have a molecular mass ranging from 1000 to 10,000 grams/mole. In one embodiment, the film-forming silicone resin or resins is/are present in the composition in a quantity ranging from 0.5% to 20% by weight with respect to the total weight of the composition, preferably in a quantity from 1% to 10%. The film-forming silicone resins advantageously comprise one or more hydrophilic groups, imparting emulsifying properties thereto. Under these conditions, the composition can contain an aqueous phase and the resin can function as a dispersant of the aqueous phase in the liquid fatty phase and conversely depending on the ratio between the hydrophilic portion and the hydrophobic (that is, silicone) portion. The resin also can be present only in the aqueous phase.  
       [0328] Not all the polymethylsilsesquioxanes are film-forming.  
       [0329] For example, the highly polymerized polymethyl-silsesquioxanes (T resins), such as TOSPEARL™ from TOSHIBA or KMP590 from SHIN-ETSU are very insoluble and because of this are therefore not effective film-forming agents.  
       [0330] The molecular mass of these polymethyl-silsesquioxanes is difficult to determine, and they generally contain a thousand or more than a thousand T moieties.  
       [0331] An example of a polymethylsilsesquioxane which can be used according to the invention is BEL SIL PMS MK, also called RESIN MK, available from WACKER CHEMIE. The polymethylsilsesquioxane is a polymer made up mainly of repeating CH 3 SiO 3/2  moieties (T moieties), and which also can contain up to approximately 1% (by weight or by mole) of (CH 3 ) 2 SiO 2/2  (D moieties). The polymers are thought to be in a “cage” and “ladder” configuration as illustrated below. It has been calculated that the weight-average molecular mass of the “cage” moiety is 536.  
       [0332] Most polymers are in the “ladder” configuration, in which the ends are stricken out with ethoxy(CH 3 CH 2 O) groups. The weight percentage of ethoxy present is approximately 4.5%, and this mole percentage is approximately 7% (silicone moieties). As this functionality can react with water, a small, variable quantity of SiOH also can be present. The weight-average molecular mass can be, for example, from approximately 50 to approximately 50,000, preferably approximately 10,000.  
                 
 
       [0333] The polymethylsilsesquioxanes suitable for a use in this invention also comprise KR-220L, available from SHIN-ETSU. The structure of KR-220L consists essentially of (CH 3 SiO 3/2 ) T silicone moieties, with Si—OH or silanol end moieties. There are no D moieties.  
       [0334] Other polymethylsilsesquioxanes which can be useful in the implementation of the invention contain KR-242A which has a structure with approximately 98% T methyl moieties and approximately 2% D dimethyl moieties, with Si—OH or silanol end moieties, and KR-251, which has a structure with approximately 88% T methyl moieties and approximately 12% D dimethyl moieties, with Si—OH or silanol end moieties; both are available from SHIN-ETSU.  
       [0335] In one embodiment of the invention, the film-forming silicone resin or resins is/are chosen from among the combinations of M, D, T and Q moieties containing at least two moieties chosen from among M, D, T and Q which satisfy the relationship RnSiO (4−n), in which n has a value ranging from  1.0 to 1.50. Some resins of this type are described in U.S. Pat. No. 6,074,654. R can be a methyl group or any carbon chain starting from the point at which the silicone resin retains its film-forming properties. Up to 5% of a silanol or alkoxy functionality also can be present in the structure of the resin, as a result of treatment thereof.  
       [0336] In order for the resin to be crosslinked, it is necessary that at least one moiety be chosen from T or Q (moiety for crosslinking via a silicon bridge), the other moiety being able to be chosen from M (end moiety) and/or D (non-crosslinked chain fragment moiety).  
       [0337] In another embodiment, the film-forming silicone resin or resins contains/contain repeating M and Q moieties. The ratio of the M moieties to the Q moieties can be, for example, approximately 0.7:1. The at least one film-forming silicone resin can be chosen, for example, from among the WACKER 803 and 804 resins, available from WACKER SILICONE CORPORATION, and G. E. 1,170-002, available from GENERAL ELECTRIC.  
       [0338] In another embodiment, the film-forming silicone resin or resins is/are a copolymer, in which at least one moiety of the copolymer is chosen from among the M, D, T and Q silicone moieties and in which at least one additional moiety of the copolymer is chosen from among the esters. Again, in order for the resin to be crosslinked, the moieties must be chosen as indicated above.  
       [0339] The film-forming silicone resin or resins can be chosen from among, for example, the diisostearoyl trimethylolpropane siloxysilicates, such as SF 1,318, available from GE SILICONES.  
       [0340] As a silicone resin which can be used in the invention, there also may be cited the organopolysiloxanes obtained (crosslinked) by hydroxysililation. These resins are able to be obtained from a silicone prepolymer of the polydialkylsiloxane type containing hydrogenosiloxane moieties pendent or at the end of the chain, which have reacted with an organic compound comprising at least 2 unsaturations of the vinyl, allyl or methallyl type. This organic compound can be a diene (hexadiene, heptadiene, octadiene), a silicone chain comprising at least 2 pendent or end vinyl or allyl groups or even a polyalkylene, preferably hydrophilic (for example with a polyoxyethylene or polyoxyethylene-polypropylene group with 1 to 40 oxyethylene or oxypropylene moieties), comprising at least 2 double bonds, pendent or at the end of the chain (and better at the end of the chain).  
       [0341] Furthermore, these resins additionally can comprise hydrophilic or hydrophobic grafts, and better hydrophilic of the polyoxyalkylene type comprising a sole unsaturation preferably at the end of the chain, the alkylene portion having from 2 to 20 carbon atoms and the hydrophilic portion from 1 to 20 oxyethylene groups. This type of graft makes it possible to impart emulsifying properties to the resin in addition to its film-forming properties.  
       [0342] As an example of resin obtained by hydroxysililation, there can be cited those described in the application EP-A-0295886. According to this application, they are obtained by addition and crosslinking reaction, in the presence of a platinum-type catalyst, of at least:  
       [0343] (a) an organopolysiloxane having at least two C 2 -C 6  lower alkenyl groups per molecule; and  
       [0344] (b) an organopolysiloxane having at least two hydrogen atoms bonded to a silicon atom per molecule. Those described in U.S. Pat. No. 5,266,321 also can be used. According to this patent, they are chosen in particular from among:  
       [0345] i) the organopolysiloxanes containing R 2 SiO and RSiO 1.5  moieties and possibly R 3 SiO 0.5  and/or SiO 2  moieties in which the R radicals, independently of each other, represent a hydrogen, an alkyl such as methyl, ethyl or propyl, an aryl such as phenyl or tolyl, an unsaturated aliphatic group such as vinyl, the ratio by weight of the R 2 SiO moieties over the RSiO 1.5  moieties ranging from 1/1 to 30/1;  
       [0346] ii) the organopolysiloxanes insoluble and expansible in silicone oil, able to be obtained by addition of an organohydrogenopolysiloxane (1) and an organopolysiloxane (2) having unsaturated aliphatic groups such that the quantity of hydrogen or of unsaturated aliphatic groups in (1) and (2) respectively ranges between 1 and 20% mol when the organopolysiloxane is noncyclic and between 1 and 50% mol when the organopolysiloxane is cyclic. These organopolysiloxanes possibly can comprise from 1 to 40 oxyalkylene and more especially oxypropylene and/or oxyethylene groups, and in particular from 1 to 20 oxyalkylene groups, all or a portion of these groups preferably being oxyethylene.  
       [0347] As examples of resins obtained by hydroxysililation which are useable according to the invention, there can be cited those marketed under the names KSG6 from Shin-Etsu, Trefil E-505C or Trefil E-506C from Dow-Corning, Gransil from Grant Industries (SR-CYC, SR DMF10, SR-DC556) or those marketed in the form of already composed gels (KSG15, KSG17, KSG16, KSG18, KSG20, KSG21, KSG31, KSG32 from Shin-Etsu, Gransil SR 5CYC gel, Gransil SR DMF 10 gel, Gransil SR DC556 gel, SF 1204 and JK 113 from General Electric. The Dow Corning DC9010 and DC 9011 and the Wacker EF199913 products also may be used; these products comprise all the oxyethylene groups, just as the KSG20, KSG21, KSG31 and KSG32 products. A mixture of these commercial products also may be used. These products are obtained in particular as described in the patents U.S. Pat. No. 5,236,986 of Shin-Etsu, U.S. Pat. No. 5,412,004 of Kosé and Shin-Etsu or also U.S. Pat. No. 5,811,487 of Dow Corning.  
       [0348] In addition, irrespective of the type of film-forming silicone resin, the latter can be crosslinked.  
       [0349] Furthermore, irrespective of the type of film-forming silicone resin, crosslinked or non-crosslinked, it possibly also can comprise a hydrophilic group or groups or grafts, in particular of the polyoxyalkylene type, such as the POEs, the PPOs and the POE/PPOs. This means that the film-forming silicone resin also can be represented in the aqueous phase as already has been mentioned above.  
       [0350] The quantities of film-forming silicone resin or resins and of structuring polymer or polymers can be chosen according to the hardness desired and the stability desired in the compositions and according to the specific application contemplated. The respective quantities of the at least one structuring polymer and of the film-forming silicone resin or resins can be such that a solid which can disintegrate and does not flow under the effect of its own weight is obtained.  
       [0351] According to the invention, the polymer can be combined with at least one amphiphilic compound liquid at room temperature, with a hydrophilic/lipophilic balance (HLB) value less than 12, in particular ranging from 1 to 7, preferably from 1 to 5, and better from 3 to 5. According to the invention, one or more amphiphilic compounds may be used. These amphiphilic compounds have the purpose of intensifying the structuring properties of the polymer, facilitating the use of the polymer and improving the depositing capacity of the stick.  
       [0352] According to the invention, the composition preferably has a hardness ranging from 20 to 2,000 gf and better from 20 to 900 gf, in particular from 20 to 600 gf and for example from 150 to 450 gf. This hardness can be measured according to a method of penetration of a probe into said composition and in particular with the aid of a texture analyzer (for example TA-TXT2i from Rheo) equipped with an ebonite cylinder 25 mm in height and 8 mm in diameter. The hardness measurement is performed at 20° C. at the center of five samples of said composition. The cylinder is introduced into each sample of composition at a pre-speed of 2 mm/s, then at a speed of 0.5 mm/s and finally at a post-speed of 2 mm/s, the total displacement being 1 mm. The recorded hardness value is that of the maximum peak. The measurement error is ±50 gf.  
       [0353] Hardness also can be measured by the so-called cheesewire method, which consists in cutting a lipstick 12.7 mm in diameter and measuring the hardness at 20° C. by means of a DFGHS 2 dynamometer from the company Indelco-Chatillon moving at a speed of 100 mm/minute. It is expressed as the shear force (expressed in gramforce) required to cut a stick under these conditions. According to this method, the hardness of a stick composition according to the invention ranges from 30 to 300 gf, preferably from 30 to 250 gf and for example from 30 to 200 gf, better from 30 to 120 gf, when the diameter of the stick is equal to 12.7 mm.  
       [0354] The hardness of the composition according to the invention is such that the composition is self-supporting and can disintegrate easily to form a satisfactory deposit on the skin and the lips. In addition, with this hardness, the composition of the invention has good impact resistance.  
       [0355] According to the invention, the solid composition, in the form of a stick has the behavior of a deformable, supple elastic solid, imparting a noteworthy elastic softness on application. The stick compositions of the prior art do not have this property of elasticity and suppleness.  
       [0356] The amphiphilic, silicone and non-silicone compound or compounds which can be used in the composition of the invention comprise a lipophilic portion associated with a polar At, portion, the lipophilic portion comprising a carbon chain having at least 8 carbon atoms, in particular from 18 to 32 carbon atoms, and better from 18 to 28 carbon atoms. The polar portion of this or these amphiphilic compound(s) preferably is the residue of a compound chosen from among the alcohols and polyols having 1 to 12 hydroxyl groups, the polyoxyalkylenes comprising at least two oxyalkylene moieties and having from 0 to 20 oxypropylene moieties and/or from 0 to 20 oxyethylene moieties. In particular, the amphiphilic compound is an ester chosen from among the hydroxystearates; the oleates; the glycerol, sorbitan or methylglucose isostearates; or even C 12  to C 26  branched fatty alcohols such as octyldodecanol and mixtures thereof. Among these esters, monoesters and mixtures of mono- and diesters are preferred.  
       [0357] The respective levels of film-forming silicone resin and structuring silicone polymer and possibly of amphiphilic compound are chosen according to the desired hardness of the gel and in terms of the specific application contemplated. The respective quantities of polymer, of film-forming silicone resin and possibly of amphiphilic compound are to be such that they make it possible to obtain a self-supporting composition, for example in the form of a cleavable stick. In practice, the quantity of polymer (in active substance) represents from 0.5 to 80% of the total weight of the composition, and better from 5 to 40%. The quantity of amphiphilic compound in practice represents from 0.1% to 35% of the total weight of the composition, for example from 1% to 20% and better from 2% to 15%.  
       [0358] According to the invention, it furthermore is preferable that the quantity of film-forming silicone resin be smaller than the quantity of structuring silicone polymer.  
       [0359] Generally, the silicone polymer/film-forming silicone resin mass ratio lies in the range from 20 to 0.15 and better from 15 to 1.5.  
       [0360] The structuring silicone polymer preferably represents 5 to 30% by weight of the composition. The silicone resin preferably represents 0.5 to 20% by weight of the composition.

       [0370] Of course, the composition of the invention should be cosmetically or dermatologically acceptable, that is, contain a non-toxic physiologically acceptable medium able to be applied to the skin, phaneric structures or lips of humans. In the meaning of the invention, cosmetically acceptable is understood as a composition with pleasant appearance, odor and feel.  
       [0371] According to the invention, the composition furthermore can contain a coloring agent which can be chosen from among the lipophilic dyes, hydrophilic dyes, and mixtures thereof.  
       [0372] This coloring agent generally is present in a proportion from 0.01 to 50% of the total weight of the composition, preferably from 5 to 30%, if it is present.

       [0375] The composition according to the invention can be manufactured by known processes generally used in the cosmetic or dermatological field. It can be manufactured by the process which consists in heating the polymer at least to its softening point, adding the oil(s), the film-forming silicone resin or resins and, if necessary, the amphiphilic compound or compounds thereto, then mixing the whole until a clear solution is obtained. There then are added, with stirring, the coloring agents and/or solid particles and the additives. The homogeneous mixture obtained then can be cast in a suitable mold such as a lipstick mold or directly into packaging articles (case or dish in particular).

     EXAMPLE 1  
     [0439] Lip gloss  
                                                           Composition               Code   (nom CTFA)   %                          Phase A   Dimethicone (20 cSt)   qsp 100               Polyglyceryl-2 diisostearate   10.0               Diisostearyl malate   6.3               Phenyltrimethicone I (20 cSt)   10.0               Phenyltrimethicone II (1000 cSt)   10.0               Isononyl isononanoate   15 5               Dimethicone and Trimethylsiloxysilicate   10.0               (MQ resin)           Phase B   Polyamidodimethylsiloxane (DP 15)   16.0           Phase C   Pigments   1.2                      
 
     [0440] This lip gloss is obtained by heating the silicone polyamide to its softening point, then adding the hydrocarbon oils, a portion of the non-volatile silicone oils and the silicone resin. Similarly, the pigments and the other portion of the non-volatile silicone oils are mixed at room temperature, and the whole is subjected to a three-cylinder grinder. The ground material obtained is added to the silicone polyamide mixture obtained, then the whole is homogenized. The mixture then is cast in an appropriate mold.  
     [0441] The product obtained in this manner has, in particular excellent staying-power properties due to the combination, according to the invention, of a film-forming silicone resin and a special silicone polymer.
