Title: Cosmetic composition for keratin fibres

Description:
The present invention relates to the field of caring for and/or making up keratin materials, and is directed towards proposing compositions more particularly intended for making up the eyelashes or the eyebrows. 
     The term “keratin materials” is preferably intended to mean human keratin materials, especially keratin fibres. 
     The term “keratin fibres” is in particular intended to mean the eyelashes and/or the eyebrows, and preferably the eyelashes. For the purposes of the present invention, this term “keratin fibres” also extends to synthetic false eyelashes. 
     In general, compositions intended for making up keratin fibres, for example the eyelashes, aim to densify the thickness and the visual perception of the eyelashes and ultimately the gaze. These mascaras are described as aqueous or else cream mascaras, when they are formulated in an aqueous base, and anhydrous mascaras when they are formulated as a dispersion in an organic solvent medium. 
     A great diversity of cosmetic effects can be provided by the application of a mascara to keratin fibres and in particular the eyelashes, for instance a volumising, lengthening, thickening and more particularly charging makeup effect. 
     These effects are mostly adjusted through the amount and nature of the particles and most particularly those of the waxes present in the mascaras. In general, mascaras in fact have a significant amount of wax(es) and in particular from 10% to 35% by weight of wax(es), more generally from 15% to 30% by weight, relative to the total weight thereof. 
     For obvious reasons, improving the textures of mascara which condition the manifestation of one or more makeup effects is a constant preoccupation of those producing cosmetic formulations. 
     Moreover, the specific effects associated with a particular formulation, for example charging and moreover providing excellent separation of the eyelashes made up, are expected to be reproduced virtually identically by all the production batches of one and the same formulation. 
     In order to meet these expectations and/or objectives, it is therefore necessary to be capable of precisely adjusting the texture of a mascara and of reproducing it as faithfully as possible with batches that are not necessarily produced at the same time but which are identical in terms of ingredients and must therefore provide makeup effects that are in theory also identical. 
     However, as specified above, most of the mascaras currently available are formulated with a significant amount of waxes. In point of fact, as detailed in the document Ullmann&#39;s Encyclopedia of Industrial Chemistry 2015, Wiley-VCH Verlag GmbH &amp; Co. KGaA, Weinheim 10.1002/14356007.a28.pub2, most waxes are not constituted of a single chemical compound, but are instead complex mixtures. They may be mixtures of oligomers and/or of polymers which, in many cases, also have varied molar masses, varied molar mass distributions and also varied degrees of branching. Thus, a polar wax is conventionally made up of a mixture of alkanes, fatty alcohols and fatty esters, the fatty-chain length of which varies according to the melting point. 
     It is therefore very difficult for the producers of these waxes to guarantee a rigorously identical composition for all production batches. More specifically, there may be, between several production batches of one and the same wax, a variability in terms of the chemical nature of some of its constituent compounds. Likewise, the proportionality of some of its constituent compounds may also vary between production batches. 
     For obvious reasons, these variabilities have a not insignificant impact on the properties of the wax and therefore on those of the mascara incorporating this wax in significant amount. Thus, two mascara formulations of identical composition and therefore produced from one and the same conventional wax in the same amount, can nevertheless diverge in terms of rheological properties and therefore of texture, if they were produced from two separate production batches of this wax. 
     Consequently, the use of conventional waxes, in particular in significant amount, in mascara compositions does not make it possible to guarantee for users the reproduction of finely adjusted and totally identical rheological properties in all the mascara specimens of one and the same composition. 
     The present invention aims precisely to provide mascara compositions which have dispensed with this limitation. 
     Thus, a first objective of the present invention is to obtain mascara compositions of which the texturing properties are finely adjustable and reproducible. 
     Another objective of the present invention is to provide a mascara architecture produced using a predominant weight proportion of single-component ingredients. The predominant use of single-component ingredients advantageously makes it possible to dispense with the risk of composition variability that may exist between several production batches of a multicomponent ingredient and therefore to dispense with the risk of its impact on the final properties of the mascara. 
     Another objective of the present invention is to provide a mascara architecture which makes it possible to significantly reduce or even dispense with the use of waxes, but which nevertheless remains very satisfactory in terms of makeup effect. 
     Thus, another objective of the invention is to provide consumers with compositions, especially cosmetic compositions, and in particular mascaras, that are compatible with a long playtime while at the same time making it possible to preserve the separation of the eyelashes. 
     Another objective of the invention is to also provide consumers with compositions which have a creamy texture. 
     Finally, an objective of the invention is to meet, for the most part, the abovementioned subjects while at the same time providing the composition with great stability. 
     The term “stable composition” is intended to mean that the composition remains usable as makeup after storage for two months at a temperature of 45° C. and that it retains its pleasantness and its sensory signature on application. More specifically, a “stable composition” according to the invention has an acceptable change in viscosity, that is to say that the difference between the initial viscosity and the viscosity after storage for two months at a temperature of 45° C. remains less than 10 Pa·s. 
     Unexpectedly, the inventors have noted that it is possible to significantly or even totally dispense with waxes as texturing agent in formulations for making up and/or caring for keratin fibres and therefore with the limitations mentioned above, with the proviso of combining very specific compounds in such formulations. 
     Thus, according to a first of its aspects, the present invention relates to a composition, preferably a cosmetic composition, in particular for caring for and/or making up keratin materials, in particular the eyelashes and/or the eyebrows, comprising:
         (1) at least one ester of polyol and of fatty acid(s), said fatty acid(s) having a number of carbon atoms greater than or equal to 20,   (2) at least one fatty acid having from 14 carbon atoms to less than 20 carbon atoms,   (3) at least one organic base, in particular derived from an alkanolamine, capable of at least partially neutralizing said fatty acid (2),   (4) at least one fatty alcohol preferably chosen from C 14 -C 30  fatty alcohols, better still chosen from the linear and saturated C 14 -C 24 , even better still C 14 -C 20 , fatty alcohols,   (5) at least one non-silicone polymeric gelling agent comprising hydrogen bonds, and   (6) water.       

     Unexpectedly, the inventors have in fact noted that the formulation in an aqueous medium of at least one ester of polyol and of fatty acid(s) (1), in combination with at least one neutralized form of a fatty acid having from 14 carbon atoms to less than 20 carbon atoms, at least one non-silicone polymeric gelling agent comprising hydrogen bonds (5) and at least one fatty alcohol (4) makes it possible to obtain compositions of which the texture can be finely adjusted and guaranteed in terms of reproducibility. 
     As emerges from what follows, these new compositions are advantageous in several respects. 
     First of all, the compounds (1) to (5) required according to the invention are of synthetic origin and, in this respect, of increased purity compared for example with a natural wax. 
     They are also, as individualized compounds, single-component compounds or compounds with a very precise number of components, as opposed to the majority of conventional waxes which are often multicomponent or even have an indefinite number of compounds, such as natural waxes and some synthetic waxes. 
     These two specificities are particularly advantageous since they make it possible to dispense with a risk of variability with regard to their respective compositions. 
     As emerges from the examples below, the compositions in accordance with the invention and based on the use of the compounds (1) to (5) as texturing agent prove to be very satisfactory in terms of makeup effects. 
     Thus, compositions according to the invention may have a creamy texture which proves to be finely adjustable by virtue of the use of the required combination according to the invention. 
     The obtaining of these properties is conditioned by the use of the compounds (1) to (5) and advantageously does not therefore require the additional presence of waxes, in particular in significant amount. 
     Thus, the compositions according to the invention advantageously comprise less than 5% of waxes as defined below. 
     The term “wax” is intended to mean lipophilic compounds, which are solid at ambient temperature (20° C.) and at atmospheric pressure (760 mmHg), with a reversible solid/liquid change of state, which have a melting point of greater than or equal to 40° C., which may range up to 120° C. 
     For the purposes of the invention, the waxes to which this abovementioned amount limitation relates are distinct from those capable of being embodied by the component which is an ester of polyol and of fatty acid(s) (1) and fatty alcohol (4) required according to the invention. 
     Finally, the manifestation of the makeup effects provided by the combination of the compounds (1) to (5) is not acquired to the detriment of the stability of the compositions. 
     According to another of its aspects, the present invention relates to a process, in particular a cosmetic process, for caring for and/or making up keratin materials, in particular the eyelashes and/or the eyebrows, comprising at least one step consisting in applying, to said keratin materials, in particular the eyelashes and/or eyebrows, a composition in accordance with the invention. 
     Ester of Polyol and of Fatty Acid(S) (1) 
     As stated above, a composition according to the invention comprises at least one ester of polyol and of fatty acid(s) (1), said fatty acid(s) having a number of carbon atoms greater than or equal to 20. 
     The composition according to the invention may comprise at least 5.0% by weight, preferably at least 6.0% by weight, better still at least 7.0% by weight of ester(s) of polyol and of fatty acid(s) relative to the total weight of the composition. 
     According to one particularly preferred embodiment of the invention, the ester(s) of polyol and of fatty acid(s) are present in the composition in a content ranging from 6.0% to 35.0% by weight, preferably from 7.0% to 30.0%, or even preferably from 8.0% to 28.0% by weight, relative to the total weight of the composition. 
     For the purposes of the invention, the term “ester of polyol and of fatty acid(s)” comprises both the monoesters and the polyesters of polyol and of fatty acid(s). 
     The composition according to the invention may comprise a single ester of polyol and of fatty acid(s) (1) or several esters of polyol and of fatty acid(s) (1). 
     If several esters are present, they can be added separately during the preparation of the composition and the mixture thereof can be formed in situ. They can also be used in the form of a mixture which is already commercially available and in which the weight proportion and the degree of purity of each of the esters are controlled. In other words, the composition of these mixtures is faithfully reproducible, as opposed to mixtures of esters of polyol and of fatty acid(s) generated via an esterification process, of which the distribution of the fatty chains of the initial reagents results in a mixture of multiple ester compounds, the composition of which is complex; for instance Kesterwax K82P, the INCI name of which is Synthetic Beeswax. 
     In particular, the ester of polyol and of fatty acid(s) is chosen from esters of glycerol and of fatty acid(s). 
     Thus, the esters of glycerol and of fatty acid(s) according to the invention correspond to formula (I) below: 
     
       
         
         
             
             
         
       
     
     in which R 1 , R 2  and R 3  can represent, independently of one another, a hydrogen atom H or a saturated or unsaturated, linear or branched acyl radical having a number of carbon atoms greater than or equal to 20, at least one of R 1 , R 2  and/or R 3  representing a saturated or unsaturated, linear or branched acyl radical having a number of carbon atoms greater than or equal to 20. 
     According to one preferred embodiment of the invention, the acyl radicals representing respectively R 1 , R 2  and R 3  are chosen in such a way that the compound of formula (I) is solid at a temperature of less than or equal to 30° C. 
     In one preferred embodiment, the esters of glycerol and of fatty acid(s) according to the invention have a melting point greater than 50° C. 
     The melting point may be measured by any known method and in particular using a differential scanning calorimeter (DSC). 
     In one preferred embodiment of the invention, when R 1 , R 2  and/or R 3  represent, independently of one another, acyl radicals, these acyl radicals are linear. 
     In one preferred embodiment of the invention, when R 1 , R 2  and/or R 3  represent, independently of one another, acyl radicals, these acyl radicals are saturated. 
     According to one particularly preferred embodiment of the invention, when R 1 , R 2  and/or R 3  represent, independently of one another, acyl radicals, these acyl radicals are linear and saturated. 
     In one preferred embodiment of the invention, when R 1 , R 2  and/or R 3  represent, independently of one another, acyl radicals, these acyl radicals are identical. 
     According to one preferred embodiment of the invention, when R 1 , R 2  and/or R 3  represent, independently of one another, acyl radicals, these radicals have a number of carbon atoms ranging from 20 to 30, preferably from 20 to 24. In particular, R 1 , R 2  and/or R 3  are chosen from arachidyl or behenyl, better still behenyl. 
     Preferably, when R 1 , R 2  and/or R 3  represent, independently of one another, acyl radicals, these radicals are behenyl radicals. 
     According to one particularly preferred embodiment of the invention, the ester(s) of polyol and of fatty acid(s) (1) is (are) chosen from a triester of glycerol and of fatty acid(s) and a mixture of a mono-, a di- and a triester of glycerol and of fatty acid(s) or mixtures thereof. 
     In particular, the ester of polyol and of fatty acid(s) is chosen from the triester of glycerol and of behenic acid (or tribehenin) and a mixture of mono-, di- and triesters of glycerol and of behenic acid(s), better still it is tribehenin. 
     The mono-, di- and triesters of glycerol and of behenic acid(s) are also found under the names glyceryl behenate, glyceryl dibehenate and glyceryl tribehenate (or tribehenin), respectively. 
     A triester of glycerol and of behenic acid that may be suitable for the invention is for example the product sold under the name Synchrowax HRC-PA-(MH) sold by the company Croda. 
     A mixture of mono-, di- and triesters of glycerol and of behenic acid(s) that may be suitable for the invention is for example Compritol 888 CG ATO sold by the company Gattefosse.

     More specifically, the ionic surfactant in question according to the invention results from the at least partial neutralization of the carboxylic functions of a fatty acid (2) comprising from 14 to less than 20 carbon atoms by an organic base (3). 
     Fatty Acid (2) 
     The fatty acid according to the invention comprises from 14 to less than 20 carbon atoms. According to one preferred embodiment of the invention, the fatty acid comprises from 16 to less than 20 carbon atoms. According to one particularly preferred embodiment, the number of carbon atoms of the fatty acid ranges from 16 to 18. 
     In particular, the fatty acid(s) according to the invention is (are) chosen from linear fatty acids, saturated fatty acids and mixtures thereof.

     As mentioned above, this fatty acid is used in an ionic form generated via its interaction with an organic base. This base is used at an amount sufficient to be capable of at least partially neutralizing at least one fatty acid (2). 
     Organic Base (3) 
     The composition according to the invention comprises at least one organic base. 
     The organic base(s) may in particularly be chosen from ammonium, and its amine and amino alcohol derivatives. 
     Preferably, the base of organic origin is chosen from alkanolamines such as monoethanolamine, diethanolamine, triethanolamine, triisopropanolamine, aminomethylpropanol, tromethamine and aminomethylpropanediol. According to one particular embodiment, the base is a primary (poly)hydroxyalkylamine. The term “primary (poly)hydroxyalkylamine” is intended to mean in particular a primary dihydroxyalkylamine, the term “primary” being intended to mean a primary amine function, i.e. —NH 2 , and the alkyl group being a linear or branched C 1 -C 8 , preferably C 4  branched, hydrocarbon-based chain, such as 1,3-dihydroxy-2methylpropyl. The primary (poly)hydroxyalkylamine is preferably 1,3-dihydroxy-2-methyl-2-propylamine (also known as aminomethylpropanediol or AMPD). 
     According to one preferred embodiment of the invention, the base of organic origin is chosen from triethanolamine, aminomethylpropanol and/or aminomethylpropanediol, and preferably comprises aminomethylpropanediol. 
     Such an aminomethylpropanediol suitable for the invention is, for example, AMPD Ultra PC sold by the company Angus (Dow Corning). 
     The amount of organic base is adjusted so as to obtain sufficient neutralization to confer an effective ionicity on the associated fatty acid (2). This adjustment clearly falls within the general competence of those skilled in the art. 
     Preferably, the organic base is present in an amount sufficient to neutralize some or all of the carboxylic functions of the fatty acid(s) (2) comprising from 14 to less than 20 carbon atoms. In one preferred embodiment, the amount of base is such that it is capable of neutralizing all the acid functions of the fatty acid (2).

     The fatty acid (2) and the organic base (3) making up the neutralized ionic surfactant according to the invention can be introduced into the composition in the form of one and the same commercial material, or one after the other in the form of two distinct commercial materials. Preferably, the fatty acid (2) and the organic base (3) will be introduced into the composition in the form of two distinct commercial materials. 
     Fatty Alcohol (4) 
     The compositions according to the invention also comprise at least one fatty alcohol. A composition can therefore comprise a single fatty alcohol according to the invention or several distinct fatty alcohols. 
     If several distinct fatty alcohols are present, they can be added separately during the preparation of the composition and the mixture thereof can then be formed in situ. They can also be used in the form of a mixture which is already commercially available and in which the weight proportion and the degree of purity of each of the fatty alcohols are controlled. In other words, the composition of these mixtures is faithfully reproducible, as opposed to mixtures of fatty alcohols generated via synthesis from starting materials derived from complex mixtures. 
     The fatty alcohol(s) is (are) in particular chosen from linear or branched, saturated or unsaturated C 14 -C 30 , preferably C 14 -C 24 , and even better still C 14 -C 20 , fatty alcohols.

     In yet another most particularly preferred embodiment, the composition according to the invention comprises:
         (1) at least tribehenin as triester of glycerol and of C 20 -C 24  fatty acid(s),   (2) at least stearic acid as fatty acid,   (3) at least aminomethylpropanediol,   (4) at least a mixture of cetyl and stearyl alcohol as fatty alcohol,   (5) at least ethylenediamine/stearyl dimer dilinoleate copolymer as non-silicone polymeric gelling agent comprising hydrogen bonds, and   (6) water.       

     Other Components 
     In addition to the abovementioned compounds, a composition according to the invention may of course comprise secondary ingredients. 
     a) Waxes 
     Thus, a composition according to the invention may also comprise a wax. 
     However, with regard to the objectives targeted by the present invention, the compositions according to the invention preferably comprise a reduced amount of wax and in particular less than 5% by weight, or even less than 3% by weight of waxes, relative to the total weight of said compositions. 
     As specified in the preamble, for the purposes of the invention, the term “waxes” is intended to mean lipophilic compounds, which are solid at ambient temperature (20° C.) and at atmospheric pressure (760 mmHg), with a reversible solid/liquid change of state, which have a melting point of greater than or equal to 40° C., which may range up to 120° C. 
     It is recalled that, for the purposes of the invention, the waxes to which the abovementioned amount limitation relates are distinct from those capable of being embodied by the component which is an ester of polyol and of fatty acid(s) (1) and/or the fatty alcohol (4) component required according to the invention. 
     This limitation relates more particularly to waxes made up of complex mixtures which are in particular described in the document Ullmann&#39;s Encyclopedia of Industrial Chemistry 2015, Wiley-VCH Verlag GmbH &amp; Co. KGaA. 
     Such waxes may in particular be natural, but may also be synthetic. 
     The term “natural” wax is intended to denote any wax which preexists naturally or which can be converted, extracted or purified from natural compounds which exist naturally. 
     Among natural waxes, mention may in particular be made of waxes termed fossil waxes, including those of petroleum origin, such as ozokerite, pyropissite, macrocrystalline waxes, also known as paraffins—including crude or gatsch waxes, gatsch raffinates, de-oiled gatsch, soft waxes, semi-refined waxes, filtered waxes, refined waxes—and microcrystalline waxes, termed microwaxes, including bright stock gatsch. The fossil waxes also contain lignite, also known as montan wax, or peat wax. 
     As natural waxes other than fossil waxes, mention may be made of animal and plant waxes. 
     As examples of plant waxes, mention may be made of carnauba wax, candelilla wax, ouricury wax, sugarcane wax, jojob waxa,  Trithrinax campestris  wax, raffia wax, alfalfa wax, wax extracted from Douglas fir, sisal wax, flax wax, cotton wax, Batavia dammar wax, cereal wax, tea wax, coffee wax, rice wax, palm wax, Japan wax, mixtures thereof and derivatives thereof. 
     As examples of animal waxes, mention may be made of beeswax, Ghedda wax, shellac, Chinese wax, lanolin, also known as wool wax, mixtures thereof and derivatives thereof. 
     These waxes are generally multicomponent. For example, natural beeswax is composed of approximately 70% of esters for the majority of monoesters (of fatty acid and of fatty alcohol), but also of hydroxy esters, of diesters and triesters and esters of sterols, and also of long-chain linear hydrocarbons, of free acids and of free alcohols. For obvious reasons, the weight portion of their ingredients and their degree of purity are difficult to guarantee from one production batch to another. 
     The term “synthetic” wax is intended to denote waxes of which the synthesis requires one or more chemical reactions carried out by a human being. 
     Among the synthetic waxes, semi-synthetic waxes and totally synthetic waxes can be distinguished. Synthetic waxes may be waxes obtained by means of a Fischer-Tropsch process, constituted for example of paraffins with a number of carbon atoms ranging from 20 to 50 or waxes of polyolefins, for example homopolymers or copolymers of ethylene, of propene or butene, or even longer-chain α-olefins. The latter can be obtained by thermomechanical degradation of polyethylene plastic, by the Ziegler process, by high-pressure processes, or else via processes catalyzed by metallocene species. These waxes may be crystallizable, partially crystallizable or amorphous. The abovementioned synthetic waxes are generally non-polar and can be chemically treated to obtain polar waxes, for example by one or more of the following reactions: air oxidation, grafting, esterification, neutralization by metal soaps, amidation, direct copolymerizations or addition reactions. 
     Again in that case, their composition may be constituted of a mixture of ingredients since the fatty-chain lengths are not well defined, thus forming a mixture of compounds having different fatty-chain lengths and for which it is difficult for manufacturers to guarantee perfect reproducibility from one production batch to another. 
     Consequently, the compositions according to the invention advantageously comprise less than 5% by weight, preferably less than 3% by weight of waxes, in particular of multicomponent natural or synthetic wax, relative to the total weight of the composition. 
     For the purposes of the invention, a multicomponent wax denotes a wax constituted of a mixture of several ingredients, either such that it exists naturally like natural waxes, or such that it is formed during the process of industrial synthesis of these materials. 
     In one particularly preferred embodiment of the invention, the composition is free of these waxes, in particular multicomponent natural or synthetic wax. 
     As specified above, the preferred texturing compounds according to the invention are by contrast and advantageously synthetic, single-component compounds, which are thus available in a form purified to more than 99%, like the compound (1) required according to the invention. 
     b) Other Surfactants 
     The composition according to the invention can comprise surfactants other than that formed by the neutralization of a fatty acid having from 14 carbon atoms to less than 20 carbon atoms (2) by the organic base (3), as co-surfactants. 
     However, according to one preferred embodiment of the invention, the composition comprises less than 5.0% by weight, preferably less than 2.0% by weight, relative to the total weight of the composition, of non-ionic surfactants, and in particular of non-ionic surfactants with an HLB, measured at 25° C., of greater than or equal to 7. 
     The term “HLB” (Hydrophilic Lipophilic Balance) is well known to those skilled in the art, and denotes the hydrophilic-lipophilic balance of a surfactant determined at 25° C. in the Griffin sense. The term “hydrophilic-lipophilic balance (HLB)” is intended to mean the equilibrium between the size and the strength of the hydrophilic group and the size and the strength of the lipophilic group of the surfactant. The HLB value according to Griffin is defined in J. Soc. Cosm. Chem. 1954 (volume 5), pages 249-256. 
     In one particularly preferred embodiment of the invention, the composition is free of non-ionic surfactants with an HLB of greater than or equal to 7. 
     c) Hydrophilic Film-Forming Polymer(s) 
     A composition according to the invention may preferably comprise at least one hydrophilic film-forming polymer. 
     For the purposes of the present invention, the term “hydrophilic polymer” is intended to mean a water-soluble polymer. 
     For the purposes of the present invention, the term “water-soluble polymer” is intended to mean a polymer which, when introduced into water at a concentration equal to 1%, gives a macroscopically homogeneous solution of which the light transmittance, at a wavelength equal to 500 nm, through a sample 1 cm thick, is at least 10%. 
     For the purposes of the present invention, the term “film-forming polymer” is intended to mean a polymer that is capable, by itself or in the presence of an auxiliary film-forming agent, of forming a macroscopically continuous deposit, and preferably a cohesive deposit, and even better still a deposit of which the cohesion and mechanical properties are such that said deposit can be isolated and manipulated individually, for example when said deposit is prepared by pouring onto a non-stick surface such as a teflonated or siliconated surface. 
     For the purposes of the invention, a hydrophilic film-forming polymer that is particularly advantageous is a (poly)vinylpyrrolidone hydrophilic polymer. 
     A (poly)vinylpyrrolidone hydrophilic polymer suitable for the invention may have a weight-average molecular weight, Mw, ranging from 1500 to 500 000 g/mol. 
     A composition according to the invention comprises a total solid content of (poly)vinylpyrrolidone hydrophilic polymer(s) of greater than or equal to 0.5% by weight, preferably greater than or equal to 1.0% by weight, more preferentially greater than or equal to 1.5% by weight, relative to the total weight of the composition. 
     The composition according to the invention preferably comprises from 0.1% to 15.0% by weight, preferably from 0.5% to 10.0% by weight, better still from 1.0% to 8.0% by weight of hydrophilic film-forming polymer(s), relative to the total weight of the composition. 
     Preferably, the (poly)vinylpyrrolidone hydrophilic polymer(s) in accordance with the invention is (are) linear. 
     In particular, the (poly)vinylpyrrolidone hydrophilic polymer(s) in accordance with the invention is (are) chosen from statistical polymers, block copolymers, and a mixture thereof. The term “block copolymer” is intended to mean a polymer comprising at least two different blocks and preferably at least three different blocks. 
     The (poly)vinylpyrrolidone hydrophilic polymer(s) is (are) chosen from:
         (poly)vinylpyrrolidone homopolymers;   copolymers of (poly)vinylpyrrolidone/(poly)vinyl acetate, esters,   copolymers of (poly)vinylpyrrolidone/(meth)acrylic, salts thereof, and a mixture thereof.       

     As (poly)vinylpyrrolidone homopolymers, mention may for example be made of:
         the polyvinylpyrrolidone (2500 g/mol) sold under the trade name Kollidon 17 PF by the company BASF,   the polyvinylpyrrolidone sold under the trade name Luviskol K 30 Powder by the company BASF or else sold under the trade name PVP K 30L by the company ISP (Ashland),   the polyvinylpyrrolidone sold under the trade name PVP K 90 by the company ISP (Ashland)       

     As (poly)vinylpyrrolidone/(poly)vinyl acetate copolymers, mention may for example be made of the vinylpyrrolidone/vinyl acetate (60/40) copolymer sold under the trade name Luviskol VA 64 Powder by the company BASF. 
     d) Liquid Fatty Phase 
     A composition according to the invention may also comprise a liquid fatty phase. 
     Such a liquid fatty phase is an organic phase that is liquid at ambient temperature (20° C.) and at atmospheric pressure (760 mmHg), non-aqueous and water-immiscible. 
     The liquid fatty phase may contain a non-volatile oil chosen from polar oils and non-polar oils, and mixtures thereof. 
     A composition of the invention may comprise from 1.0% to 20.0% by weight, from 2.0% to 12.0% by weight and preferentially from 2.0% to 8.0% by weight of non-volatile oil, relative to the total weight of the composition. 
     A composition according to the invention generally comprises less than 5.0% by weight, preferably less than 2.0% by weight of volatile oil(s), relative to the total weight of the composition. In one particularly preferred embodiment of the invention, the composition is free of volatile oils. 
     The term “volatile oil” is intended to mean an oil that can evaporate on contact with the skin in less than one hour, at ambient temperature (20° C.) and atmospheric pressure (760 mmHg). More specifically, a volatile oil has an evaporation rate ranging from 0.01 to 200 mg/cm 2 ·min. 
     e) Colorant 
     A composition according to the invention, and in particular those intended for makeup, generally comprises at least one colorant such as pulverulent colorants, liposoluble dyes or water-soluble dyes. 
     The pulverulent colorants can be chosen from pigments and pearlescent agents. 
     The pigments may be white or coloured, mineral and/or organic, and coated or uncoated. Mention may be made, among mineral pigments, of titanium dioxide, optionally surface treated, zirconium, zinc or cerium oxides, and also iron or chromium oxides, manganese violet, ultramarine blue, chromium hydrate and ferric blue. Among the organic pigments that may be mentioned are carbon black, pigments of D &amp; C type and lakes based on cochineal carmine, on barium, strontium, calcium or aluminium. 
     The pearlescent agents may be chosen from white pearlescent pigments such as mica coated with titanium or with bismuth oxychloride, coloured pearlescent pigments such as titanium mica with iron oxides, titanium mica especially with ferric blue or chromium oxide, titanium mica with an organic pigment of the abovementioned type, and also pearlescent pigments based on bismuth oxychloride. 
     The liposoluble dyes are, for example, Sudan Red, D&amp;C Red 17, D&amp;C Green 6, β-carotene, soybean oil, Sudan Brown, D&amp;C Yellow 11, D&amp;C Violet 2, D&amp;C Orange 5, quinoline yellow and annatto. 
     Preferably, the composition according to the invention comprises a pulverulent colorant, preferably of pigment type, in particular metal oxides. 
     Preferably, said colorant is present in the composition in a content ranging from 2.0% to 25.0% by weight, preferably from 3.0% to 20.0%, more particularly from 4.0% to 15.0% by weight, relative to the total weight of the composition. 
     f) Cosmetic Active Agents 
     As cosmetic active agents that may be used in the compositions according to the invention, mention may be made in particular of antioxidants, preservatives, fragrances, neutralizers, cosmetic active agents, for instance emollients, vitamins and screening agents, in particular sunscreens, and mixtures thereof. 
     These additives may be present in the composition in a content ranging from 0.01% to 15.0% of the total weight of the composition. 
     Of course, those skilled in the art will take care to choose the optional additional additives and/or their amounts in such a way that the advantageous properties of the composition according to the invention are not, or are not substantially, detrimentally affected by the envisaged addition. 
     Physical Characteristics 
     a) Solid Content 
     The composition according to the invention advantageously has a solid content at least equal to 42.0% by weight, and preferentially at least 44.0% by weight relative to the total weight of the composition, or even from 45.0% to 60.0% by weight, relative to the total weight of the composition. 
     For the purposes of the present invention, the “solid content” denotes the content of non-volatile matter. 
     The amount of solid content (abbreviated as SC) of a composition according to the invention is measured using a commercial halogen desiccator Halogen Moisture Analyzer HR 73 from Mettler Toledo. The measurement is performed on the basis of the weight loss of a sample dried by halogen heating, and thus represents the percentage of residual matter once the water and the volatile matter have evaporated off. 
     This technique is fully described in the machine documentation supplied by Mettler Toledo. 
     The measuring protocol is as follows: 
     Approximately 2 g of the composition, referred to hereinbelow as the sample, are spread out on a metal cup, which is placed in the halogen desiccator mentioned above. The sample is then subjected to a temperature of 105° C. until a constant weight is obtained. The wet weight of the sample, corresponding to its initial weight, and the dry weight of the sample, corresponding to its weight after halogen heating, are measured using a precision balance. 
     The experimental error associated with the measurement is of the order of plus or minus 2%. 
     The solid content is calculated in the following manner: 
       Solid content (expressed as weight percentage)=100×(dry weight/wet weight).
 
     b) Viscosity 
     A composition according to the invention is advantageously creamy at an ambient temperature of 20° C. 
     It is characterized by a viscosity of less than 40 Pa·s, or even preferably less than 35 Pa·s, or even less than 30 Pa·s, measured at an ambient temperature of 20° C. using an RM100® Rheomat. 
     Preferably, the viscosity of the compositions according to the invention ranges from 2.0 to 40.0 Pa·s, or even preferably from 2.5 to 35.0 Pa·s, more particularly from 3.0 to 30.0 Pa·s, measured at the ambient temperature of 20° C. using an RM100® Rheomat. Such a viscosity is particularly advantageous since it is the most suitable for the device for applying mascara and since it enables easy use for the consumer for a charging result. 
     The composition may be produced via the known processes generally used in the cosmetics field. 
     The composition used according to the invention may be a makeup composition, a makeup base, in particular for keratin fibres, or base coat, a composition to be applied onto makeup, also known as topcoat, or else a composition for treating keratin fibres. 
     More especially, the composition according to the invention is a mascara. 
     Such compositions are especially prepared according to the general knowledge of those skilled in the art. 
     The expressions “between . . . and . . . ” and “ranging from . . . to . . . ” should be understood as being inclusive of the limits, unless otherwise specified. 
     In the description and the examples, the percentages are percentages by weight, unless otherwise indicated. The percentages are thus given by weight relative to the total weight of the composition. The ingredients are mixed in the order and under conditions that are readily determined by those skilled in the art. 
     The invention will now be described by means of examples which are present purely for illustrative purposes and should not be interpreted as examples that limit the invention. 
    
    
     EXAMPLE 1 
     A composition of mascara type, in accordance with the invention (Composition 1) and two compositions outside the invention (Compositions 2 and 3) were prepared as described below. 
     Preparation of Phase A 
     The starting materials were carefully weighed out beforehand using a balance (precision=0.01 g). The ingredients of phase A were melted in a jacketed heating pan in which circulates an oil of which the temperature is controlled by means of a thermostatic oil bath. The setpoint temperature was fixed at 90° C. After total melting, the pigment was introduced with stirring using a Rayneri blender. Stirring was maintained until a homogeneous preparation was obtained. 
     Preparation of Phase B 
     The water was preheated in an electric kettle to 95° C. The preservatives and the organic base were introduced into the water in a beaker at a temperature of 80° C. with stirring using a Rayneri blender. 
     Emulsification of Phases A and B 
     Phase B was poured into phase A with stirring for 5 minutes at 90° C. using a Rayneri blender. Phase A+B was then cooled to ambient temperature with stirring. 
     End of Formulation 
     The mascara thus obtained was transferred into a closed container to prevent it from drying out on contact with air. After 24 h, the macroscopic homogeneity of the sample and the state of dispersion of the fatty substances and of the pigment were evaluated under an optical microscope and the viscosity was measured.

     The stability of the compositions was examined after all the above compositions had spent two months at 45° C. The texture of the sample which was at 45° C. is then compared with that of the sample which remained at ambient temperature. 
     As described above, a stable composition is a composition which retains its texture and its homogeneity and the application of which remains pleasant. Conversely, a composition is described as unstable if its texture has become much thicker, if phase separation appears or if the composition is no longer pleasant on application. 
     All of the results obtained are reported in the following table:

Composition 1 exhibits performance levels suitable for being used for eyelash care and/or makeup purposes.
 
On the other hand, the compositions outside the invention do not prove to be satisfactory in terms of stability.
