Description

METHOD FOR NlAKING UP OR CARING FOR EYELASHES OR EYEBROWS USING A POLYALKENE-BASED SUPRAMOLECULAR

POLYMER

One subject of the present invention is a method for coating eyelashes or eyebrows comprising the application to the eyelashes or the eyebrows of a composition comprising at least one polyalkene-based supramolecular polymer. The composition according to the invention may be in the form of a mascara.

The term "mascara" is understood to mean a composition intended to be applied to the eyelashes: it may be an eyelash makeup composition, an eyelash makeup base, a composition to be applied over a mascara, also known as a topcoat, or else a cosmetic composition for treating eyelashes. The mascara is more particularly intended for human eyelashes, but also for false eyelashes . Generally, eyelash makeup compositions are composed of at least one wax or of a mixture of waxes dispersed in an aqueous liquid phase or in an organic solvent phase.

Anhydrous mascaras or mascaras with a low content of water and/or water-soluble solvents, which are known as "waterproof mascaras", formulated in the form of a dispersion of waxes in non-aqueous solvents, and which have good resistance to water and/or to sebum, are known in particular. However, the makeup film obtained after application of these compositions is not sufficiently water-resistant, when bathing or showering for example, to tears or to sweat or else to sebum. The mascara then has a tendency to run - appearance of rings under the eyes - or to disintegrate over time: grains are deposited and unattractive marks appear around the eyes .

In order to improve the hold of mascaras known as waterproof mascaras, it has been proposed to incorporate a liposoluble film-forming polymer or a polymer in the form of a dispersion of particles in an organic solvent phase, at a higher content of film- forming polymer. However, the presence of a high content of film- forming polymer is reflected by a pasty texture of the composition, which forms, after being deposited on the keratin fibres, a granular, non-uniform film that lacks slipperiness on application. The objective of the present invention is therefore to provide a composition for making up or coating keratin fibres, especially eyelashes or eyebrows, which has good water resistance and/or sebum resistance properties, and also good rubbing resistance properties.

Unexpectedly, the inventors have discovered that the use of a polyalkene-based supramolecular polymer, formulated in a continuous oily phase in the presence of a colorant, makes it possible to obtain a composition having a good water resistance and/or sebum resistance, and also a very good resistance to rubbing.

The expression "water resistance" is understood according to the present application to mean the in vitro water resistance evaluated according to the following protocol:

The composition is applied to 3 samples of straight Caucasian hair having 30 knots (60 eyelashes 1 cm in length) with a fringe length of 2 cm, by making 3 x 10 passes at 2 minute intervals with uptake of product between each series of 10 passes. Each sample is then dried at ambient temperature for a drying time of one hour.

The 3 made-up samples are immersed in a container containing water at 20⁰C for a given time (1 hour, 24 hours or 1 week) . The 3 samples are then wiped back and forth 5 times on a square cloth of the Wypall L40 type from Kimberly Clark.

The presence of marks deposited by the sample is then evaluated. A score between 0 and 9 is attributed to the resulting marks; 0 being the score obtained when no mark is deposited by the sample, and 9 the score obtained when a large number of marks are deposited. The expression "sebum resistance" is understood according to the present application to mean the in vitro sebum resistance evaluated according to the same measurement protocol as for the water resistance described above, except that the 3 made-up samples are immersed in a container containing squalene (the squalene is present at 18% in the composition of sebum), instead of water.

The expression "rubbing resistance" is understood according to the present application to mean the in vitro rubbing resistance evaluated according to the following protocol:

The made-up sample is then positioned perpendicularly above a sheet of paper and rubbed using a hard brush of the Keracils® type (30 passes) .

The quantity of grains thus formed, recovered on the sheet of paper, is evaluated.

A score between 0 and 6 is attributed to this quantity of grains; 0 being the score for which no grain is recovered on the sheet of paper and 6 the score for which a very large quantity of grains is recovered.

One subject of the present invention is therefore a method for making up or caring for eyelashes or eyebrows comprising the application to the eyelashes or the eyebrows of at least one layer of a cosmetic composition comprising a continuous oily phase, at least one polyalkene-based supramolecular polymer, and at least one colorant.

Using this process, a deposit is obtained on the eyelashes or the eyebrows that has a good resistance to water and sebum, and also a very good resistance to rubbing.

Another subject of the present invention is an assembly for making up or caring for eyelashes or eyebrows comprising:

- at least one composition comprising a continuous oily phase, at least one polyalkene-based supramolecular polymer and at least one colorant,

- and at least one applicator of the composition, said applicator comprising means that make it possible to smooth and/or separate the eyelashes or eyebrows, especially in the form of teeth, bristles or other reliefs .

The compositions according to the invention are thus used for making up and/or caring for keratin fibres, in particular eyelashes, for example as mascaras.

The process for making up or coating eyelashes or eyebrows according to the invention consists, in particular, in applying an effective amount of a composition as described above, to the eyelashes or the eyebrows.

APPLICATOR

The applicator included in the makeup or care assembly according to the present invention comprises means that make it possible to smooth and/or separate the eyelashes or eyebrows, especially in the form of teeth, bristles or other reliefs.

The application means, or applicator, may be used to apply the composition to the eyelashes or the eyebrows.

The applicator may also be used for finishing the making-up process in one region of the eyelashes or of the eyebrows made up or loaded with product using another applicator. The composition according to the invention may be withdrawn from a container by immersing the application member into this container.

The application part may comprise, optionally, a member for closing a container that contains the composition according to the invention.

The process of applying the composition according to the invention to the eyelashes or the eyebrows may also comprise the following steps: - forming a deposit of the cosmetic composition on the eyelashes or the eyebrows; and

- leaving the deposit on the eyelashes or the eyebrows, the deposit possibly drying.

The application member is arranged in order to apply a product to the eyelashes or the eyebrows, and may comprise, for example, a brush or a comb.

The brush may comprise a twisted core and bristles held between the turns of the core, or may be produced in yet another way. The comb is, for example, produced from a single part by moulding of a plastic.

The application member may be magnetic.

In certain exemplary embodiments, the application member is mounted at the end of a wand, which wand may be flexible, which may contribute to improving the comfort during application.

The applicator may or may not comprise a reservoir that contains the composition.

When the applicator does not comprise a reservoir that contains the composition, the composition is, for example, contained in a container and the application member is, for example, loaded with composition by being introduced at least partially into this container. The container may or may not comprise a wiping member.

The reservoir may be fastened in a removable or unremovable manner to the applicator. When the reservoir is permanently fastened to the applicator, in order to supply the latter with product, the wall of the reservoir is used, for example, for gripping the applicator .

The assembly according to the invention may also comprise at least two different application members which may be selectively mounted on the applicator.

The assembly will be better understood on reading the detailed description which follows of non-limiting exemplary embodiments of this assembly, and on examining the appended drawing, in which: - Figure 1 schematically represents, with a partial longitudinal cross section, a packaging and application device according to one exemplary embodiment of the invention.

Figure 1, to which reference is now made, illustrates a packaging and application device 1 according to one embodiment of the invention. According to this embodiment, the packaging and application assembly comprises an applicator 2 and a container 3 that contains a reserve of a makeup product P, in this particular case a composition according to the invention, for example mascara.

The container 3 is conventional in the example illustrated and comprises a body 5 equipped with an externally threaded neck 6. A wiping member 7 is fastened inside the neck 6.

The applicator 2 comprises an application member 10 constituted, in the example in question, of a mascara brush. The application member 10 is mounted at the end of a wand 11, the other end of which is attached to a case 13 comprising an end part arranged so as to screw onto the neck 6 and thus seal the container 3 in a leaktight manner.

In this figure, the brush has been represented very schematically in order to clearly illustrate the fact that the invention is not limited to one particular application member.

The brush 10 comprises, for example, bristles, the ends of which are arranged in helical layers.

The wand may be produced with a constant or variable cross section.

Preferably, the wand 11 is flexible, a person skilled in the art being able to choose the dimensions of the wand as a function, for example, of the nature of the application member, of the product and of the treatment to be carried out.

When the application member is configured in the form of a comb, the latter may be in accordance with what is described, in particular, in the publications US 2003-0089379-A1, US 6 655 390, US 6 814 084, US 6 675 814, US 6 581 610, US 6 546 937, US 6 539 950, US 6 412 496 or US 6 343 607, this list not being limiting.

The invention is not limited to one particular application member and the latter may especially be equipped with a means that makes it possible to heat the product and/or the eyelashes and/or the eyebrows during the application.

Various modifications may be made to the exemplary embodiments which have just been described without departing from the scope of the present invention.

The application members may be of any type, especially with capillary slits or the like.

The application members may be made in various ways, especially by moulding, injection-moulding, staple fastening or twisting.

The application members may be intended for single use, where appropriate.

The application members may be fastened by any means to the application part, especially by bonding, welding, punching, click-fastening, screwing, with magnets, by friction, by attachment of Velcro® type, by gripping between jaws or the arms of pincers.

The application member may be driven in rotation, where appropriate, for example as described in patents US 4 937 326, US 4 922 934 and US 6 565 276.

The application of the product may be carried out, especially when the invention is implemented in order to apply a product to the eyelashes or the eyebrows, after having heated the product, for example by placing it in a microwave oven.

The composition according to the invention may be packaged in a container delimiting at least one compartment which comprises said composition, said container being sealed by a sealing member.

The container may be associated with the applicator .

The applicator may be attached to the container, as described, for example, in patent FR 2 761 959. Advantageously, the applicator is attached to a wand which, itself, is attached to the sealing member.

The sealing member may be coupled to the container by screwing. Alternatively, the coupling between the sealing member and the container takes place other than by screwing, especially via a bayonet mechanism, by click-fastening or by clamping. The term "click- fastening" is understood to mean, in particular, any system that involves surmounting a rim or bead of material by elastic deformation of a portion, especially of the sealing member, then by returning to the elastically unstressed position of said portion after the rim or bead has been surmounted.

The container may be at least partly made of a thermoplastic. As examples of thermoplastics, mention may be made of polypropylene or polyethylene.

Alternatively, the container is made from a non- thermoplastic material, especially from glass or from metal or an alloy. The container is preferably equipped with a wringer placed in the vicinity of the opening of the container. Such a wringer makes it possible to wipe the applicator and optionally the wand to which it may be attached. Such a wringer is described, for example, in patent FR 2 792 618.

Polyalkene-based supramolecular polymers

Within the meaning of the present invention, the expression "polyalkene-based supramolecular polymer" is understood to mean a polymer comprising, in its structure, at least one polyalkene part and at least one part comprising at least one group capable of forming at least 3 H bonds, preferably 4 H bonds. The polyalkene is preferably chosen from poly (ethylene/butylene) s, polybutadienes and polyisoprenes .

The polyalkene-based supramolecular polymers according to the invention may be derived from the condensation of at least one polyalkene polymer functionalized by at least one reactive group, with at least one graft functionalized by at least one reactive group capable of reacting with the reactive group or groups of the functionalized polyalkene polymer, said graft bearing at least one group capable of forming at least 3 H bonds, preferably at least 4 H bonds.

Preferably, the functionalized polyalkene polymer is of formula A:

HX-R-X'H XH and X' H being reactive groups, with X and X', which are identical or different, chosen from O, S, NH, or NR_a, R_a representing a Ci-Cε alkyl group; preferably, X and/or X' denote O; more preferably still, X and X' denote O; R represents a homopolymer or a copolymer derived from one or more monounsaturated or polyunsaturated C2-C10, and preferably C2-C4, alkenes; R preferably represents a poly (ethylene/butylene) , a polybutadiene or a polyisoprene . Thus, preferably, the functionalized polyalkene polymer is chosen from hydroxyl-terminated poly (ethylene/butylene) s, hydroxyl-terminated polybutadienes and hydroxyl-terminated polyisoprenes.

The poly (ethylene/butylene) s are copolymers of 1-butene and ethylene. They can be represented schematically by the sequence of units of structures:

[-CH₂-CH₂-] and [-CH₂CH(CH₂-CH₃)]. The polybutadienes may be poly (1, 4-butadiene) s or poly (1, 2-butadiene) s, which may be respectively represented schematically by the sequences of following units :

[-CH₂-CH=CH-CH₂-] poly (1, 4-butadiene) s [-CH₂-CH(CH=CH₂) -] poly (1,2-butadiene) s. Preferably, for the polybutadienes, they are poly (1, 2-butadiene) s .

The functionalization preferably takes place at the end of the chains. Reference is then made to telechelic polymers. The functionalization groups may be attached to the polyalkene polymer via linkers, preferably linear or branched Ci-C₄ alkylene groups.

These polyalkenes may be hydrogenated in order to avoid risks of crosslinking.

They may comprise, in their structure, other units resulting from other monomers. As comonomers, mention may in particular be made of styrene.

Polydienes, preferably hydrogenated polydienes having hydroxyl end groups and polyolefins having hydroxyl end groups are preferred polymeric backbones according to the invention.

These hydroxyl-terminated polydienes are defined, for example, in patent FR 2 782 723 by Elf Atochem. They are chosen from the group comprising homopolymers and copolymers of polybutadiene, of polyisoprene and of poly (1, 3-pentadiene) . They are oligomers having a number-average molecular weight of less than 7000, and preferably of 1000 to 5000, having a functionality of hydroxyl end groups of 1.8 to 3, and preferably in the vicinity of 2. Mention will in particular be made of the hydroxylated polybutadienes sold by Elf Atochem under the trade marks POLY BD R-45HT and POLY BD R-20 LM, which will preferably be used in hydrogenated form. Mention may also be made of the di-OH hydrogenated poly (1,2-butadiene) s, such as GI3000 of M_n = 2600-3200 and GI2000 of M_n = 1800-2200 sold by Nisso.

Use may also be made of polyolefins, which are homopolymers or copolymers, having CC, CO-hydroxyl end groups, such as: • polyisobutylene oligomers having CC, Cϋ-hydroxyl end groups; and

• the copolymers sold by Mitsubishi under the trade mark POLYTAIL with, in particular, those corresponding to the formula:

-NH —C—O- —C- —C-

These functional groups can be categorized into two categories: - functional groups which donate H bonds, such as the groups :

C=CH -SH -OH C=NH -NH -NH2

- and functional groups which accept H bonds, such as the groups : \ \ \ \

C=O C=S C=N- S=O

/ / /

— C≡N r o- —C- —c-

The groups capable of forming at least 3 H bonds form a base structural element comprising at least 3 functional groups, preferably at least 4 functional groups and more preferably 4 functional groups capable of establishing H bonds. The base structural elements capable of establishing 3 or 4 H bonds can be represented schematically in the following way:

A proton acceptor X will be paired with a proton donor Y. Several possibilities are offered, for example pairing of: XXXX with YYYY; XXXY with YYYX; XXYX with YYXY; XYYX with YXXY; XXYY with YYXX, which may or may not be self- complementary;

XYXY with YXYX, which may or may not be self- complementary.

Preferably, the groups can establish 4 H bonds with an identical (or self-complementary) partner group, among which 2 donor bonds (for example NH) and 2 acceptor bonds (for example CO and -C=N-) .

Preferably, the groups capable of forming at least 3 H bonds comprise rings having 5 or 6 atoms (aromatic rings or unsaturated heterocycles) , very often constituted of C and/or N atoms and with conjugated double bonds in order to stabilize and control the H interactions .

More preferably, the groups capable of forming at least 3 H bonds are involved in rings having 6 atoms comprising C and/or N atoms and with conjugated double bonds in order to stabilize and control the H interactions .

In practice, the supramolecular polymer according to the invention can be prepared by the processes normally employed by a person skilled in the art, in order to form a urethane bond between the free OH functional groups of a polyalkene and the isocyanate functional groups borne by the joining group.

By way of illustration, a general preparation process comprises:

- making sure that the polymer to be functionalized does not comprise residual water;

- heating the polymer comprising at least two reactive functional groups, especially OH, to a temperature which can be between 60° C and 140 °C. The hydroxyl number of the polymer could act as reference in order to measure the state of progression of the reaction; directly adding the joining group bearing the reactive functional groups, in particular isocyanate functional groups;

- stirring the mixture, under a controlled atmosphere, at a temperature of the order of 90-130 °C, for 1 to 24 hours; monitoring, by infrared spectroscopy, the disappearance of the band characteristic of the isocyanates (between 2500 and 2800 cm^"1) , so as to halt the reaction at the complete disappearance of the peak, and then allowing the final product to return to ambient temperature;

- the reaction could also be monitored by quantitative determinations of the hydroxyl functional groups; - it could also be possible to add ethanol in order to make sure that the residual isocyanate functional groups have completely disappeared;

- the mixture could be filtered if necessary.

The reaction can be carried out in the presence of a solvent, in particular methyltetrahydrofuran, tetrahydrofuran, toluene, butyl acetate or else propylene carbonate.

It is also possible to add a catalyst conventional for the formation of the urethane bond. Mention may be made, as example, of dibutyltin dilaurate.

At the end, the compound can be washed and dried, indeed even purified, according to the general knowledge of a person skilled in the art.

According to the 2^nd method of preparation, the reaction can comprise the following stages:

(i) functionalization of the predried polyhydroxylated polyalkene polymer P, by a diisocyanate according to the reaction scheme:

OH-P-OH (1 eq.) + NCO-X-NCO (1 eq.) → OCN-X-NH-(O)CO-P- OC(O)-NH-X-NCO

The diisocyanate can optionally be in excess with respect to the polymer. This first stage can be carried out in the presence of solvent, at a temperature of between 20°C and 100°C. This first stage can be followed by a period of stirring, under a controlled atmosphere, for a period ranging from 1 hour to 24 hours. The mixture can optionally be heated. The state of progression of this first stage can be monitored by quantitative determination of the hydroxyl functional groups; then

(ii) reaction of the prepolymer obtained in stage (i) with 6-methylisocytosine :

OCN-X-NH-(O)CO-P-OC(O)-NH-X-NCO

This second stage can optionally be carried out in the presence of a cosolvent, such as toluene, butyl acetate or else propylene carbonate. The reaction mixture can be heated at between 80 °C and 140 °C for a time varying between 1 hour and 24 hours.

The presence of a catalyst can promote the production of the desired final product. Mention may be made, for example, of the use of dibutyltin dilaurate.

The reaction can be monitored by infrared spectroscopy, by monitoring the disappearance of the peak characteristic of the isocyanate between 2200 and 2300 cm^"1.

At the end of the reaction, ethanol can be added to the reaction medium in order to neutralize the residual isocyanate functional groups. The reaction mixture can optionally be filtered. For application purposes, the polymer could be directly stripped in a cosmetic solvent.

Wax (es)

The wax under consideration in the context of the present invention is generally a lipophilic compound which is solid at ambient temperature (25°C), which exhibits a reversible solid/liquid change in state and which has a melting point of greater than or equal to 30⁰C which can range up to 200⁰C and in particular up to 120°C. On bringing the wax to the liquid state (melting) , it is possible to render it miscible with oils and to form a microscopically homogeneous mixture but, on bringing the temperature of the mixture back to ambient temperature, recrystallization of the wax in the oils of the mixture is obtained.

In particular, the waxes suitable for the invention can exhibit a melting point of greater than or equal to 45°C and in particular of greater than or equal to 55°C.

Within the meaning of the invention, the melting point corresponds to the temperature of the most endothermic peak observed by thermal analysis (DSC) as described in the standard 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 "MDSC 2920" by TA Instruments . The measurement protocol is as follows:

A 5 mg sample of wax placed in a crucible is subjected to a first rise in temperature ranging from -20⁰C to 100⁰C at a heating rate of 10°C/minute, is then cooled from 100⁰C to -20°C at a cooling rate of 10°C/minute and, finally, is subjected to a second rise in temperature ranging from -20⁰C to 100⁰C at a heating rate of 5°C/minute. During the second rise in temperature, the variation in the difference in power absorbed by the empty crucible and by the crucible comprising the sample of wax is measured as a function of the temperature. The melting point of the compound is the value of the temperature corresponding to the tip of the peak of the curve representing the variation in the difference in power absorbed as a function of the temperature.

The waxes capable of being used in the compositions according to the invention are chosen from waxes of animal, plant, mineral or synthetic origin, and their mixtures, which are solid at ambient temperature.

The waxes which can be used in the compositions according to the invention generally exhibit a hardness ranging from 0.01 MPa to 15 MPa, in particular of greater than 0.05 MPa and in particular of greater than 0.1 MPa.

The hardness is determined by the measurement of the compressive force measured at 20⁰C using a texture analyser sold under the name TA-XT2 by Rheo, equipped with a stainless steel cylinder with a diameter of 2 mm which is displaced at the measuring rate of 0.1 mm/s and which penetrates the wax to a penetration depth of 0.3 mm. The measurement protocol is as follows:

The wax is melted at a temperature equal to the melting point of the wax + 10⁰C. The molten wax is cast in a receptacle with a diameter of 25 mm and a depth of 20 mm. The wax is recrystallized at ambient temperature (25°C) for 24 hours, so that the surface of the wax is flat and smooth, and then the wax is stored at 20⁰C for at least one hour before measuring the hardness or the tack. The rotor of the texture analyser is displaced at the rate of 0.1 mm/s and then penetrates the wax to a penetration depth of 0.3 mm. When the rotor has penetrated the wax to the depth of 0.3 mm, the rotor is held stationary for 1 second (corresponding to the relaxation time) and is then withdrawn at the rate of 0.5 mm/s.

The value of the hardness is the maximum compressive force measured divided by the surface area of the cylinder of the texture analyser in contact with the wax.

Mention may in particular be made, by way of illustration of the waxes suitable for the invention, of hydrocarbon-based waxes, such as beeswax, lanolin wax and Chinese insect waxes; rice bran wax, carnauba wax, candelilla wax, ouricury wax, esparto wax, berry wax, shellac wax, Japan wax and sumac wax; montan wax, orange and lemon waxes, microcrystalline waxes, paraffin waxes and ozokerite; polyethylene waxes, the waxes obtained by the Fischer-Tropsch synthesis and waxy copolymers, and their esters.

Mention may also be made of waxes obtained by catalytic hydrogenation of animal or plant oils having linear or branched C8-C32 fatty chains. Mention may in particular be made, among these, of hydrogenated sunflower oil, hydrogenated castor oil, hydrogenated coconut oil, hydrogenated lanolin oil and di (1,1,1- trimethylolpropane) tetrastearate, sold under the name of Hest 2T-4S® by Heterene.

Mention may also be made of silicone waxes or fluorinated waxes.

Use may also be made of the waxes obtained by hydrogenation of castor oil esterified with cetyl alcohol which are sold under the names of Phytowax

Castor 16L64® and 22L73® by Sophim. Such waxes are described in application FR-A-2 792 190.

According to a specific embodiment, the compositions according to the invention can comprise at least one wax referred to as a "tacky wax", that is to say having a tack of greater than or equal to 0.1 N. s and a hardness of less than or equal to 3.5 MPa.

The tacky wax used can have in particular a tack ranging from 0.1 N. s to 10 N.s, in particular ranging from 0.1 N.s to 5 N.s, preferably ranging from 0.2 to 5 N.s and better still ranging from 0.3 to 2 N.s.

The tack of the wax is determined by the measurement of the change in the force (compressive force) as a function of the time at 20⁰C according to the protocol indicated above for the hardness.

During the relaxation time of 1 s, the force (compressive force) strongly decreases until it becomes zero and then, during the withdrawal of the rotor, the force (stretching force) becomes negative to subsequently again increase towards the value 0. The tack corresponds to the integral of the curve of the force as a function of the time for the part of the curve corresponding to the negative values of the force. The value of the tack is expressed in N.s. The tacky wax which can be used generally has a hardness of less than or equal to 3.5 MPa, in particular ranging from 0.01 MPa to 3.5 MPa, especially ranging from 0.05 MPa to 3 MPa. Use may be made, as tacky wax, of a C20-C40 alkyl (hydroxystearyloxy) stearate (the alkyl group comprising from 20 to 40 carbon atoms), alone or as a mixture. Such a wax is sold in particular under the names "Kester Wax K 82 P®" and "Kester Wax K 80 P®" by Koster Keunen.

In the present invention, use may also be made of waxes provided in the form of small particles having a size, expressed as volume-average "effective" diameter D[4,3], of the order of 0.5 to 30 micrometres, in particular of 1 to 20 micrometres and more particularly of 5 to 10 micrometres, subsequently denoted by the expression "microwaxes" .

The sizes of the particles can be measured by various techniques. Mention may in particular be made of light scattering techniques (dynamic and static) , Coulter counter methods, measurements by rate of sedimentation (related to the size via Stokes' law) and microscopy. These techniques make it possible to measure a particle diameter and, for some of them, a particle size distribution.

Preferably, the sizes and size distributions of the particles of compositions according to the invention are measured by static light scattering using a commercial particle sizer of MasterSizer 2000 type from Malvern. The data are processed on the basis of the Mie scattering theory. This theory, exact for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" particle diameter. This theory is described in particular in the work by Van de Hulst, H. C, "Light Scattering by Small Particles", Chapters 9 and 10, Wiley, New York, 1957. The composition is characterized by its volume- average "effective" diameter D [4, 3], defined in the following way:

where V₁ represents the volume of the particles with an effective diameter Cl₁. This parameter is described in particular in the technical documentation of the particle sizer.

The measurements are performed at 25°C on a dilute particle dispersion, obtained from the composition in the following manner: 1) dilution by a factor of 100 with water, 2) homogenization of the solution, 3) standing of the solution for 18 hours, 4) recovery of the whitish homogeneous supernatant. The "effective" diameter is obtained by taking a refractive index of 1.33 for the water and a mean refractive index of 1.42 for the particles.

Mention may in particular be made, as microwaxes which can be used in the compositions according to the invention, of carnauba microwaxes, such as that sold under the name of MicroCare 350^® by Micro Powders, synthetic wax microwaxes, such as that sold under the name of MicroEase 114S^® by Micro Powders, microwaxes composed of a mixture of carnauba wax and of polyethylene wax, such as those sold under the names of Micro Care 300^® and 310^® by Micro Powders, microwaxes composed of a mixture of carnauba wax and of synthetic wax, such as that sold under the name Micro Care 325^® by Micro Powders, polyethylene microwaxes, such as those sold under the names of Micropoly 200^®, 220^®, 220L^® and 250S^® by Micro Powders, and polytetrafluoroethylene microwaxes, such as those sold under the names of Microslip 519^® and 519 L^® by Micro Powders.

The composition according to the invention can comprise a content of waxes ranging from 5 to 70% by weight, with respect to the total weight of the composition; in particular, it can comprise from 7 to 50% by weight thereof, more particularly from 10 to 45% by weight thereof.

Pastes The composition according to the invention may comprise at least one pasty compound.

The term "pastes" is understood, within the meaning of the present invention, to mean a lipophilic fatty compound having a reversible solid/liquid change in state and comprising, at a temperature of 23°C, a liquid fraction and a solid fraction.

The pasty compound preferably has a hardness at 20⁰C ranging from 0.001 to 0.5 MPa, preferably from 0.002 to 0.4 MPa. The hardness is measured according to a method of penetration of a probe into a sample of compound and in particular using a texture analyser (for example, the TA-XT2i from Stable Micro Systems Ltd.) equipped with a stainless steel cylinder with a diameter of 2 mm. The hardness measurement is carried out at 20⁰C at the centre of 5 samples. The cylinder is introduced into each sample at a pre-rate of 1 mm/s and then at a measuring rate of 0.1 mm/s, the depth of penetration being 0.3 mm. The value recorded for the hardness is that of the maximum peak.

This pasty compound is, additionally, at a temperature of 23°C, in the form of a liquid fraction and of a solid fraction. In other words the starting melting point of the pasty compound is below 23°C. The liquid fraction of the pasty compound measured at 23°C represents from 23 to 97% by weight of the compound. This liquid fraction at 23°C preferably represents between 40 and 85% by weight of the compound.

The liquid fraction by weight of the pasty compound at 23°C is equal to the ratio of the enthalpy of fusion consumed at 23°C to the enthalpy of fusion of the pasty compound.

The enthalpy of fusion of the pasty compound is the enthalpy consumed by the compound to change from the solid state to the liquid state. The pasty compound is "in the solid state" when the whole of its mass is in the solid form. The pasty compound is "in the liquid state" when the whole of its mass is in the liquid form.

The enthalpy of fusion of the pasty compound is equal to the area under the curve of the thermogram obtained using a differential scanning calorimeter (DSC) , such as the calorimeter sold under the name MDSC 2920 by TA Instrument, with a rise in temperature of 5 or 10⁰C per minute, according to standard ISO 11357- 3:1999. The enthalpy of fusion of the pasty compound is the amount of energy necessary to change the compound from the solid state to the liquid state. It is expressed in J/g.

The enthalpy of fusion consumed at 23°C is the amount of energy absorbed by the sample to change from the solid state to the state which it exhibits at 23°C, composed of a liquid fraction and of a solid fraction. The liquid fraction of the pasty compound measured at 32°C preferably represents from 40 to 100% by weight of the compound, preferably from 50 to 100%, preferably from 80 to 100%, more preferably from 90 to 100% by weight of the compound. When the liquid fraction of the pasty compound measured at 32°C is equal to 100%, the temperature of the end of the melting range of the pasty compound is less than or equal to 32°C.

The liquid fraction of the pasty compound measured at 32°C is equal to the ratio of the enthalpy of fusion consumed at 32°C to the enthalpy of fusion of the pasty compound. The enthalpy of fusion consumed at 32⁰C is calculated in the same way as the enthalpy of fusion consumed at 23°C.

When the crystallizable portion is in the form of a crystallizable block of the polymer backbone, the amorphous portion of the polymer is in the form of an amorphous block; in this case, the semi-crystalline polymer is a block copolymer, for example, of the diblock, triblock or multiblock type, comprising at least one crystallizable block and at least one amorphous block. The term "block" is generally understood to mean at least five identical repeat units. The crystallizable block(s) is (are) thus of chemical nature different than that of the amorphous block (s) .

EXAMPLES

In the following examples, the viscosity of the compositions is measured according to the following protocol :

The viscosity of the composition is measured at 25°C using a Rheomat 180 (Lamy) equipped with an MS-Rl, MS-R2, MS-R3, MS-R4 or MS-R5 spindle chosen as function of the consistency of the composition, which rotates at a rotational speed of 200 rpm. The measurement is taken after rotating for 10 min. The viscosity measurements are carried out a maximum of 1 week after manufacture.

EXAMPLE 1 (according to the invention)

The following composition is produced:

Preparation of the polymer Ia:

100 g of GI3000 polymer sold by Nisso are dried at 80⁰C, under vacuum overnight. This polymer is put into solution in 400 ml of anhydrous toluene. 25 μl of catalyst, dibutyltin dilaurate, are added to the reaction mixture. The medium is heated at 80⁰C, and mixed until a homogeneous solution is obtained. 15 g of isocyanate-functionalized molecule with the following structure:

in solution in 300 ml of anhydrous toluene, are added under a controlled atmosphere at 40⁰C. The reaction mixture is heated at 100⁰C and stirred at this temperature for 4 hours. The reaction is monitored by infrared spectroscopy, with monitoring of the complete disappearance of the peak characteristic of the isocyanates at 2260 cm^"1. At the end of the reaction, 100 ml of ethanol are added in order to remove any trace of residual isocyanate, the mixture is filtered after having added isododecane in order to render the solution less viscous. The polymer solution is then directly stripped with isododecane.

The final polymer is obtained with a solids content of 16% in isododecane and is characterized by GPC (M_n = 6400 and polydispersity index of 1.85) and ¹H NMR (spectrum in accordance with what is expected) .

Preparation of the composition:

phase A is heated at 100⁰C with stirring in a Rayneri agitator; phase C is introduced into phase A until a good dispersion is obtained; the bentone gel B is prepared and placed in a waterbath (60-70⁰C); - B is introduced into the A+C mixture, homogenized for 5 minutes at high temperature, then extruded through a three-roll mill (3 passes) .

A composition is obtained that has a shiny homogeneous texture with good viscosity (95 poise) .

COMPARATIVE EXAMPLE

The following comparative composition is produced:

This comparative composition is prepared according to the same protocol as that of Example 1.

A composition is obtained having a shiny homogeneous texture with good viscosity (24 poise) .

The hold of the composition of Example 1 and of the comparative composition on the eyelashes is then tested by the protocols described below:

It is therefore observed that the composition 1 has a better dry rubbing resistance than the comparative composition, for an equivalent water and sebum resistance.
