LO layer phase The surfactant system according to the invention is organized in the form of a lamellar phase Lp, or paracrystalline phase 43, or lamellar gel phase.  This composition is stable at room temperature of 25 ° C.  having a viscosity preferably ranging from 5 to 50 Pa. s, measured at room temperature of 25 ° C using a Rhéomat RM1000.  By gel or paracrystalline lamellar phase 143 is meant a phase in which the molecules of surfactants and / or more generally of amphiphilic compounds are organized in the form of bimolecular layers spaced apart by aqueous sheets.  Within the bimolecular layers, the molecules are distributed according to a hexagonal geometry, their hydrocarbon chains are in a crystalline state and are oriented perpendicular to the plane of the binnolecular layers but have no specific orientation with respect to each other in the plane of these layers.

The paracristalline phases Lp are metastable phases in which the fatty chains are in the solid state and are randomly arranged relative to each other, unlike the paracristalline micellar, hexagonal, cubic and lamellar fluid phases (La) within of which the fatty chains are in the liquid state, and in contrast to the crystalline phases in which the fatty chains are in the solid state and oriented in an orderly manner with respect to each other. Lp paracrystalline phases are metastable and, in general, they tend to evolve towards crystallization. However, the Applicant has found a particular surfactant system to obtain a stable Lp paracristalline phase, and thus cosmetic compositions for coating keratinous fibers, in particular eyelashes, which are stable and comfortable to apply, of good strength and volume, using a particular system of surfactant type according to particular contents. In order to identify the Lf3 gel or paracrystalline lamellar phase of the surfactant system present in the composition of the invention, it is possible to use various techniques, and in particular the X-ray diffraction technique. Wide angle X-ray Scattering (WAXS) X-ray diagrams were recorded by a Mar345 (Maresearch, Norderstedt, Germany) plate-plate detector mounted on an X-ray generator. FR591 rotary anode (Bruker, Courtaboeuf, France), used at 50 kV and 50 mA. Monochromatic CuKa radiation (λ = 1.541 Å) was focused with a focal spot of 350 μm to 320 mm by double reflection on a multilayered Montel mirror of elliptical cross section (Incoatec, Geesthacht, Germany). The beam was defined under vacuum by four motorized carbon-tungsten slots (JJ-Xray, Roskilde, Denmark) positioned in front of the mirror (500 μm). Four additional protection slots were placed at the focal point at a separation distance of the slots of 220 mm. The flow downstream of the mica exit windows was 3 x 108 photons / sec. A 2 mm diameter circular wire harness was placed in the air 150 mm downstream of the sample and the detector was positioned at 360 mm. X-ray patterns were therefore recorded for a reciprocal spacing range q = 4sin 0 / λ of 0.03-1.8 Å-1, where 0 is the diffraction angle. Recurrent distances d = 2t / q should be between 200Å and 3.5Å. The samples were placed in 1.2-1.3 mm glass capillaries (Glas W. Müller, Germany) and introduced into a homemade capillary fixing device, which can hold up to 20 capillaries at a temperature of controlled. Particles The compositions of an assembly according to the present invention comprise particles of hard wax (es) and preferably of film-forming polymer (s), preferably present in the form of aqueous dispersion (s). These particles can be characterized by an average particle size. Such particles are generally isotropic, in particular of substantially spherical or spherical shape. Particle size A particle size can be measured by different techniques. In particular, light scattering techniques (dynamic and static), Coulter sensor methods, sedimentation rate measurements (connected to size via the stokes law) and microscopy can be mentioned. These techniques make it possible to measure a particle diameter and, for some of them, a particle size distribution. Preferably, the sizes and particle size distributions of the compositions according to the invention are measured by static light scattering by means of a commercial Master Sizer 2000 type granulometer from Malvern. The data is processed on the basis of Mie scattering theory. This theory, which is accurate for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" diameter of particles. This theory is described in particular in Van de Hulst, HC, "Light Scattering by Small Particles", Chapters 9 and 10, Wley, New York, 1957. In the context of the present invention, the "average particle size "Is expressed in mean" effective "diameter in volume D [4.3], defined as follows: - d, D [4, 3] - I LT7 where V; represents the volume of particles of effective diameter di. This parameter is described in particular in the technical documentation of the granulometer. The measurements are carried out at 25 ° C. on a diluted particle dispersion. The "effective" diameter is obtained by taking a refractive index of 1.33 for water and an average refractive index of 1.45 for particles. Thus, preferably, the particles of the compositions in accordance with the invention, comprising at least one hard wax and preferably at least one film-forming polymer, preferentially present in the form of aqueous dispersions, have an average size expressed as an average "effective" diameter by volume. D [4.3] less than or equal to 5 μm, in particular strictly less than 5 μm, more preferably less than 2 μm, and still more preferably less than or equal to 1 μm. Such particle sizes preferably correspond to the size of the particles in the final composition. This average size of particles is advantageous in terms of the implementation of the composition according to the present invention compared to compositions comprising particles of hard waxes and film-forming polymers of larger sizes which result in a mascara difficult or impossible to formulate , granular, too thick, inapplicable (too compact and not friable), uncomfortable, with poor dispersion of pigments and fillers, and matte color. It is understood that the surfactant system (s) will (have) tend to position itself at the interface of the aqueous phase and the hard wax particles, and possibly particles of film-forming polymers, to stabilize them. The measured particle sizes are therefore in the presence of the agent (s) surfactant (s), being difficult to dissociate the particles. The sizes measured and given reflect this feature. As regards the other particles of the composition, for example dyestuffs and fillers, these compounds will be treated independently in another paragraph of the description, the size characteristics of this type of particles diverging with respect to the particle sizes of the waxes and film-forming polymers conforming to the invention.

Wax (es) The wax (es) is (are) in general a lipophilic compound, solid at room temperature (25 ° C.), with a reversible solid / liquid state change, having a point of melting greater than or equal to 30 ° C up to 200 ° C and in particular up to 120 ° C. For the purposes of the invention, the melting temperature corresponds to the temperature of the most endothermic peak observed in thermal analysis (DSC) as described in ISO 11357-3; 1999. The melting point of the wax can be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name "DSC Q2000" by the company TA Instruments. Preferably, the waxes have a heat of fusion A.Hf greater than or equal to 70 J / g. Preferably, the waxes comprise at least one crystallizable part, visible by X-ray observations. The measurement protocol is as follows: A sample of 5 mg of wax placed in a crucible is subjected to a first temperature rise of -20. ° C at 120 ° C, at the heating rate of 10 ° C / minute, then is cooled from 120 ° C to -20 ° C at a cooling rate of 10 ° C / minute and finally subjected to a second rise in temperature ranging from -20 ° C to 120 ° C at a heating rate of 5 ° C / minute. During the second rise in temperature, the following parameters are measured: the melting point (Tf) of the wax, as previously mentioned, corresponding to the temperature of the most endothermic peak of the observed melting curve, representing the variation of the difference in power absorbed as a function of temperature, - A.Hf: the melting enthalpy of the wax corresponding to the integral of the whole of the melting curve obtained. This enthalpy of fusion of the wax is the amount of energy required to pass the compound from the solid state to the liquid state. It is expressed in J / g. The wax (es) may be hydrocarbon (s), fluorinated (s) and / or silicone (s) and may be of vegetable, mineral, animal and / or synthetic origin. The wax (es) may be present at a total content greater than or equal to 10% by weight relative to the total weight of the composition, better still at 15% by weight relative to the total weight of the composition. Preferably, it (they) is (are) present in a content ranging from 10 to 30% by weight relative to the total weight of the composition, more preferably from 15 to 30% by weight. A composition according to the invention comprises at least one hard wax, preferably present in the preparation of the composition in the form of an aqueous dispersion of particle (s) of wax (es). Hard wax According to the invention, the composition more specifically comprises at least one hard wax. By "hard wax" in the sense of the present invention is meant a wax having a melting temperature ranging from 65 to 120 ° C, more preferably between 70 and 100 ° C. Advantageously, "hard" wax within the meaning of the present invention means a wax having, at 20 ° C., a hardness greater than 5 MPa, in particular ranging from 5 to 30 MPa, preferably greater than 6 MPa, more preferably ranging from 6 to 25 MPa. To perform these hardness measurements, the wax is melted at a temperature equal to the melting point of the wax + 20 ° C. For this purpose, 30 g of wax are placed in a 100 mm diameter beaker 50 mm in diameter, itself positioned on a heating magnetic stirring plate. About 15 g of melted wax are poured into a stainless steel container 80 mm in diameter and 15 mm deep and heated to 45 ° C. in an oven. The wax is then allowed to crystallize in a thermostatically controlled room at 20 ° C. for 24 hours before making the measurement. The mechanical properties of the wax or of the mixture of waxes are determined in a room thermostatically controlled at 20 ° C. using the texturometer sold under the name TA-XT2i by the company Swantech, equipped with a stainless steel cylinder of a diameter 2 mm. The measurement comprises 3 steps: a first step after automatic detection of the surface of the sample where the mobile moves at the measurement speed of 0.1 mm / s, and penetrates into the wax at a depth of penetration of 0, 3 mm, the software notes the value of the maximum force reached; a second so-called relaxation stage where the mobile stays at this position for one second and where the force is noted after 1 second of relaxation; finally a third so-called withdrawal step where the mobile returns to its initial position at the speed of 1 mm / s and the energy of withdrawal of the probe (negative force) is recorded.

The value of the hardness corresponds to the maximum compression force measured in Newton divided by the surface of the cylinder of the texturometer expressed in mm 2 in contact with the wax. The value of hardness obtained is expressed in mega-pascals or MPa.
