Description:

METHOD FOR MAKING UP OR CARING FOR THE EYELASHES OR EYEBROWS USING A POLYSILOXANE/POLYUREA BLOCK COPOLYMER

The subject of the present invention is a method for coating the eyelashes or the eyebrows comprising the application, to the eyelashes or the eyebrows, of a composition comprising a polysiloxane/polyurea block copolymer .

The composition according to the invention may be provided in the form of a mascara or a product for the eyebrows. More especially, the invention relates to a mascara .

The expression mascara is understood to mean a composition intended to be applied to the eyelashes: this may be a makeup composition for the eyelashes, a makeup base for the eyelashes, a composition to be applied over a mascara, also called top-coat, or a composition for the cosmetic treatment of the eyelashes. The mascara is more particularly intended for the eyelashes of human beings, but also for false eyelashes .

In general, makeup compositions for the eyelashes consist of at least one wax or 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, called "waterproof mascaras" , formulated in the form of a dispersion of waxes in nonaqueous solvents and which have a good resistance to water or to sebum are known in particular.

However, the makeup film obtained after the application of these compositions is not sufficiently resistant to water, during swimming or showers for example, to tears or to perspiration or to sebum. The mascara then tends to run - appearance of halos under the eyes - or to crumble over time: grains are deposited and unaesthetic marks appear around the eyes.

To improve the staying power of so-called

waterproof mascaras, it has been proposed to incorporate a fat-soluble film- forming polymer or a polymer in the form of a dispersion of particles in an organic solvent phase, in a high content of film- forming polymer. However, the presence of the film- forming polymer in a large amount results in a pasty texture of the composition which forms, after deposition on keratin fibres, a nonhomogeneous granular film lacking slip upon application. The aim of the present invention is therefore to provide a makeup or coating composition for keratin fibres, in particular the eyelashes or the eyebrows, having good properties of resistance to water, to sebum and/or to rubbing, which completely or partially solves the problems linked to the conventional formulation routes, and which can be easily removed.

Unexpectedly, the inventors have discovered that the use of a polysiloxane/polyurea block copolymer, in particular which is nonionic, formulated in the presence of an organic solvent and a pigment, makes it possible to obtain a composition having good resistance to water, to sebum and to rubbing. The composition thus obtained is also easy to remove.

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

The composition is applied to 3 test pieces of straight Caucasian hair 30 knots (60 eyelashes 1 cm long) length of fringe 2 cm, making 3 x 10 passes 2 minutes apart, with recovery of product between each series of 10. Each test piece is then dried at room temperature for a drying time of one hour.

The 3 made-up test pieces are immersed in a vessel containing water for a given time (1 hour, 24 hours or 1 week) . Five to-and-fro movements of the 3 test pieces are then performed on a square Wypall L40 type wipe from Kimberly-Clark.

The presence of a mark deposited by the test piece

is then evaluated.

The expression "resistance to sebum" is understood to mean, according to the present application, the resistance to sebum in vitro evaluated according to the same measurement protocol as for the resistance to water described above, the difference being that the 3 made-up test pieces are immersed in a vessel containing squalene (the squalene is present at 18% in the composition of the sebum) , instead of water. The subject of the present invention is therefore a method for making up or caring for the eyelashes or the eyebrows comprising the application, to the eyelashes or the eyebrows, of at least one coat of a cosmetic composition comprising at least one nonionic polysiloxane/polyurea block copolymer, at least one volatile nonsilicone organic solvent and at least one dye substance.

By this method, a deposit is obtained on the eyelashes or the eyebrows which has good resistance to water and to sebum, and to rubbing. The said deposit is also easy to remove.

The subject of the present invention is also a makeup or care set for the eyelashes or the eyebrows comprising : - at least one composition comprising a nonionic polysiloxane/polyurea block copolymer, at least one volatile nonsilicone organic solvent and at least one dye substance , - and at least one applicator for the composition, the said applicator comprising means which make it possible to smooth and/or separate the eyelashes or the eyebrows .

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

The method for making up or coating the eyelashes or the eyebrows according to the invention consists in applying an effective quantity of the composition as

described above, to the eyelashes or the eyebrows. APPLICATOR

The applicator contained in the makeup or care set according to the present invention comprises means which make it possible to smooth and/or separate the eyelashes or the eyebrows . These means may in particular be provided in the form of teeth, bristles or other reliefs.

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

The applicator may also be used for finishing the makeup, on an area of the eyelashes or the eyebrows that has been made up or loaded with product by means of another applicator. The composition according to the invention may be collected from a vessel by dipping the application element therein.

The application part may optionally contain an element for closing a vessel containing the composition according to the invention.

The applicator may for example be provided in the form of a brush or a comb.

The brush may contain a twisted core and bristles held between the turns of the core, or may be made in yet another way.

The comb is for example made of a single part by moulding of plastic material.

The application element may be magnetic.

In some exemplary embodiments, the application element is mounted at the end of a wand, which may be flexible, which can contribute towards improving comfort during application.

The applicator may or may not comprise a reservoir containing the composition. When the applicator does not comprise a reservoir containing the composition, the composition is for example contained in a vessel and the application element is for example loaded with composition by being at least partially introduced into this vessel. The

vessel may or may not comprise a draining part.

The reservoir may or may not be detachably attached to the applicator. When the reservoir is permanently attached to the applicator, in order to supply it with product, the wall of the reservoir serves for example for prehension of the applicator.

The set according to the invention may also contain at least two different application elements which may be selectively mounted on the applicator. The set will be understood more clearly on reading the detailed description which follows, of nonlimiting examples of the use thereof, and on examining the accompanying drawing, in which: figure 1 schemmatically represents, in partial longitudinal section, a packaging and application device in accordance with an exemplary embodiment of the invention.

Figure 1, to which reference is made, illustrates a packaging and application device 1 in accordance with one embodiment of the invention.

According to this embodiment, the packaging and application set comprises an applicator 2 and a vessel 3 containing a reservoir for a makeup product P, in this case a composition according to the invention, for example mascara. The vessel 3 is classic in the example illustrated and contains a body 5 provided with an externally threaded neck 6. A draining part 7 is attached inside the neck 6.

The applicator 2 contains an application element 10 constituted, in the example considered, by a mascara brush. The application element 10 is mounted at the end of a wand 11 whose other end is integrally attached to a box 13 containing an end part designed so as to screw onto the neck 6 and thus seal the vessel 3. In this figure, the brush has been very schematically represented so as to clearly illustrate the fact that the invention is not limited to a particular application element.

The brush 10 contains for example bristles whose

ends are arranged like helical sheets.

The wand may be made with a constant or non- constant cross section.

Preferably, the wand 11 is flexible, it being possible for persons skilled in the art to choose the dimensions of the wand for example according to the nature of the application element, of the product and of the treatment to be carried out .

When the application part is configured in the form of a comb, the latter may be in conformity 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 a particular application element and the latter may in particular be provided with a means which makes it possible to heat the product and/or the eyelashes and/or the eyebrows during 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 elements may be of any type, in particular having capillary grooves or the like. The application elements may be made in various ways, in particular by moulding, superinjection, fastening or twisting.

The application elements may be for single use, where appropriate. The application elements may be attached by any means to the application part, in particular by adhesive bonding, soldering, drop forging, snapping on, screwing, with magnets, by friction, by VELCRO® type coupling, by clamping between the jaws or arms of tweezers.

The application element 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 applicator contains in particular a plurality

of application elements arranged on a support in the form of at least one row whose length is such that the application elements can best come simultaneously into contact with at most a quarter of the eyelashes or the eyebrows of the fringe so as to smooth them and/or separate them.

According to a preferred embodiment, the applicator according to the invention contains:

- a wand, - a support connected to the wand and extending along a longitudinal axis, and

- a plurality of application elements, only two in number where appropriate, arranged on the support and extending substantially at right angles to the longitudinal axis of the support.

Thus, according to a most particularly preferred embodiment, the applicator contains a plurality of application elements arranged on a support in the form of at least one row whose length is such that the application elements can best come simultaneously into contact with at most a quarter of the eyelashes or the eyebrows of the fringe.

The application elements may extend over a distance along the longitudinal axis of the support which is such that the application elements can best come simultaneously into contact with at most a quarter, or even a fifth or a sixth of the eyelashes or the eyebrows of the fringe, while the longitudinal axis of the support is oriented substantially tangentially to the fringe.

A portion of the made-up eyelashes or eyebrows may for example correspond to at most a quarter, or even a fifth or a sixth of the length of the fringe.

The application elements may contain teeth and/or bristles.

This applicator makes it possible to appropriately deposit the composition on the eyelashes or the eyebrows while exerting an optional combing action.

The application elements extend over the support

over a sufficiently short distance to be able to make up one or more locks of eyelashes or eyebrows, which makes it possible to obtain novel makeup effects.

This applicator makes it possible to deposit in a sustained manner material over only at most a third, or even a quarter of the fringe of the eyelashes or the eyebrows to be made up, preferably the portion which is outside the fringe of eyelashes or eyebrows.

The application elements may for example extend over the support over a distance of between about 0.1 and 1 cm, for example less than or equal to 8 mm, or even 7 mm or 6 mm, for example a distance ranging from 2 mm to 5 mm approximately, for example between 2 mm and 3 mm . The applicator contained in the set according to the present invention may contain:

- a wand,

- a support connected to the wand and extending along a longitudinal axis, - at least one row of application elements, in particular consisting of teeth, arranged over the support, the application elements of the row each extending substantially at right angles to the longitudinal axis of the support and having free ends whose distance to the longitudinal axis varies non- monotonously on moving between the application elements at the far ends of the row.

The expression "varying non-monotonously" for the purposes of the present invention should be understood to mean that the line connecting the free ends of the application elements has a distance to the longitudinal axis of the support which passes through at least one extremum, for example one maximum.

The presence of a maximum in the row of application elements may allow gradual penetration of the application elements into the eyelashes or the eyebrows and thus facilitate the making up of a portion of the fringe of eyelashes or eyebrows for the purposes of the invention.

The number of application elements of the row, in particular the number of teeth, may be for example between 3 and 9, preferably between 3 and 8, in particular between 3 and 7. According to one embodiment, the support and the application elements are made of a single part, in particular by moulding or machining. As a variant, the application elements may be mounted on the support.

The support and the wand may be made of a single part, in particular by moulding or, as a variant, the support may be mounted on the wand. In this case, the support may contain a tip designed to fit into a housing on the wand or the wand may contain a tip designed to fit into a housing of the support. The wand may extend along a longitudinal axis distinct from the longitudinal axis of the support.

In this case, the longitudinal axis of the wand may form, with the longitudinal axis of the support, in particular for the portion thereof which carries the application elements, an angle between 5° and 45°, in particular between 15° and 25°, for example equal to 20° approximately. This configuration may allow a more convenient handling of the applicator during the application of a makeup composition in accordance with the invention to the eyelashes or the eyebrows. The longitudinal axis of the support may be for example curvilinear or rectilinear.

The wand may, as a variant, extend along a longitudinal axis merged with the longitudinal axis of the support.

The applicator and/or the support may at least partially be made of a flexible or rigid material, in particular at least partially made of a thermoplastic, elastomeric or elastomeric thermoplastic material, in particular by moulding. There will be no departure from the scope of the present invention if the applicator is at least partially made of wood or of metal or of other materials, in particular by machining.

When the support is made of an elastically

deformable material, this may make it possible to carry out preferential draining of one side of the support.

The wand and the support may or may not be made of different materials. When the applicator is viewed from the side, a line connecting the free ends of the application elements may have a distance to the longitudinal axis of the support which passes through at least one extremum, in particular a maximum, which may make the penetration of the applicator into the eyelashes more gradual .

The abovementioned line may have in particular, at least partially, a pointed, in particular triangular, or round, in particular circular or ogival, shape. Regardless of the profile of the abovementioned line, when there is a maximum and a minimum, the angle formed between, on the one hand, the straight line connecting the free ends of an application element of greater length associated with this maximum and an application element of shorter length associated with a minimum that is closest to the application element of greater length, and on the other hand the perpendicular to the longitudinal axis of the support, this perpendicular passing through the free end of the application element of greater length, is for example between 25° and 60° approximately, in particular between 25° and 50°, in particular between 25° and 45°, for example between 30° and 45°, for example equal to 43° approximately. The distance from the abovementioned line to the longitudinal axis of the support may also pass through two extrema, or even more.

The application elements may be arranged in a single row or in at least two rows. In the latter case, the application elements of a first row and those of a second row may extend in different directions or, as a variant, in parallel directions. The two rows may for example be arranged substantially opposite each other relative to the support.

The height of the application elements may be for example between 0.5 and 10 mm approximately, in particular between 1 and 3 mm approximately.

When the application elements are arranged in at least one row, the latter may contain a succession of application elements extending alternately, at least partially, on either side of a geometric surface of separation.

The application elements may have bases that are aligned or otherwise.

When the application elements are arranged in at least one row, the row may extend along a nonrectilinear axis. The application elements may also be produced alternately on either side of a median core.

Still when the application elements are arranged in at least one row, this row may contain a succession of application elements alternately located, at least partially, on either side of a geometric surface of separation, two consecutive application elements having adjacent parts that are contiguous or that overlap when the applicator is viewed from the side and forming with each other a hollow which makes it possible to receive an eyelash or an eyebrow therein. The applicator may contain a comb or a brush.

When the applicator contains a brush, the support may contain two twisted wires having a small diameter, in particular less than 0.7 mm, for example between 0.2 and 0.6 mm, even better between 0.35 and 0.5 mm. Still in the case where the applicator contains a brush, the application elements may be bristles having a small diameter, for example less than or equal to 8/100 mm, even better 6/100 mm.

When the brush contains a twisted core, the number of turns of the brush may be between 3 and 6, for example. In the case of a brush having a twisted core, the bristles extend from the core along two helical sheets. The number of turns of the brush corresponds to the sum of the revolutions around the core of the two

sheets. Part of the twisted core may be free of bristles, in particular near the junction between the support and the wand. The cross section of the envelope surface of the brush may be circular, square or otherwise.

The brush may have a biconical envelope surface. The envelope surface may also be conical or frusto- conical with the base of the cone located on the side of the distal or proximal end of the brush. The applicator contained in the set according to the invention may take the form of a brush for the application of a product to the eyelashes or the eyebrows, containing a twisted core and bristles extending from the core, the number of turns being less than or equal to 6.

The applicator contained in the set according to the invention may also take the form of a brush for the application of a product to the eyelashes or the eyebrows, containing a core and bristles extending from the core, the length of the portion of the brush bearing the bristles being less than or equal to 8 mm, even better to 7 mm or even to 6 mm.

The applicator contained in the set according to the invention may contain a core and bristles extending from the core, contained in an envelope surface having a substantially frustoconical , conical or biconical shape, in which the smallest angle formed between a plane containing the largest cross section of the brush and a tangent to the envelope surface of the brush at the intersection with this plane is between 20° and 60°, in particular between 25° and 50°, for example between 30° and 35°.

The applicator contained in the set according to the invention may contain a core and bristles extending from the core, in which the envelope surface of the brush has a substantially biconical shape, with an apex angle at the junction of the truncated cones less than or equal to 120°, or even less than or equal to 90°.

The applicator contained in the set according to

the invention may contain a support and teeth extending at right angles to the longitudinal axis of the support, the distance between the furthest teeth along the longitudinal axis being less than or equal to 8 mm, even better 7 mm, or even 6 mm.

The applicator contained in the set according to the invention may contain a support and teeth extending at right angles to the longitudinal axis of the support, containing a tooth of greater length having a first length and a tooth of shorter length having a second length, a comb in which the ratio of the first length to the second length is greater than or equal to 1.3.

The applicator contained in the set according to the invention may contain a support and teeth extending at right angles to the longitudinal axis of the support, in which the angle formed between a straight line joining the free end of a tooth of shorter length and the free end of a tooth of greater length and the perpendicular to the longitudinal axis of the support passing through the free end of the tooth of greater length is between 20° and 60°.

The applicator according to the invention may be provided in the form of a brush containing an arrange- ment of bristles maintained by a twisted wire. Such a twisted brush is described in particular in patent US 4 887 622. It may also be in the form of a comb containing a plurality of application elements, obtained in particular by moulding. Such combs are described, for example, in patent FR 2 796 529.

The composition according to the invention may be packaged in a vessel delimiting at least one compartment which comprises the said composition, the said vessel being closed by a closing element. The vessel may be combined with the applicator.

The applicator may be integrally attached to the vessel, as patent FR 2 761 959 describes for example. Advantageously, the applicator is integrally attached to a wand which is itself integrally attached to the

closing element.

The closing element may be coupled to the vessel by screwing. Alternatively, the coupling between the closing element and the vessel is achieved other than by screwing, in particular via a bayonet fitting mechanism, by snap fastening, or by tightening. The expression "snap fastening" is understood to mean in particular any system involving passing through a flange or a bead of material by elastic deformation of a portion, in particular of the closing element, and then by returning to the elastically unstressed position of the said portion after passing through the flange or the bead.

The vessel may be at least partially made of a thermoplastic material. By way of examples of thermoplastic materials, there may be mentioned polypropylene or polyethylene.

Alternatively, the vessel is made of a non- thermoplastic material, in particular of glass or of metal or an alloy.

The vessel is preferably equipped with a draining device near the opening of the vessel . Such a draining device makes it possible to wipe the applicator and, optionally, the wand to which it may be integrally attached. Such a draining device is described, for example, in patent FR 2 792 618. COPOLYMER

In the present invention, the copolymer is a nonionic polysiloxane/polyurea copolymer, that is to say that it does not contain an ionized or ionizable group .

In the context of the invention, the expression block copolymer is understood to mean a copolymer consisting of at least two blocks distinct from each of the polymers constituting the copolymer in the copolymer backbone. For example, the copolymer of the invention contains at least one polysiloxane block and at least one polyurea block in the copolymer backbone.

The copolymer of the invention may comprise, in

addition to the polysiloxane/polyurea, other blocks of different polymers, for example at least one polyurethane block. There may be mentioned in particular the polysiloxane/polyurea/polyurethane block copolymers .

The copolymers of the invention may be obtained according to the methods of polymerization described in patent application US 2004/0254325 or application WO 03/014194.

The copolymer may thus be obtained by a two- stage method, such as:

- in the first stage, a silazane of general formula (2) or (2' ) :

W representing a hydrogen atom, a substituted or unsubstituted hydrocarbon radical, preferably comprising from 1 to 20 carbon atoms or a radical R 2 Si-X-NH 2 ; is reacted with an organic silicon compound of general formula (3) : (HO) (R 2 SiO) n - ! [H] (3) so as to obtain an aminoalkylpolydiorganosiloxane of general formula (4)

H 2 N-X-[SiR 2 O] n SiR 2 -X-NH 2 (4)

- in a second stage, the aminoalkylpolydiorgano- siloxane of general formula (4) is polymerized with a diisocyanate of general formula (5) :

OCN-Y-NCO (5)

In general, in the first stage, the silazanes of general formula (2) or (2') and the reagents containing the silanol groups are used in equimolar ratios.

For the preparation of silicones with bisamino- alkyl ends that are very pure, of general formula (4) , a small excess of the silazane compound of general formula (2) or (2') is preferably used, which may then be removed, in a simple additional process step, such as for example the addition of small quantities of water .

If b is at least 1, it is possible to use, during the second stage, up to 95% by weight, based on all the components used, of chain extension agents, which are chosen from diamines, hydroxyl compounds that are blocked by an isocyanate, dihydroxyl compounds or mixtures thereof .

Preferably, the chain extension agents have the general formula (6) :

HZ -X- ZH ( 6 ) where D and Z have the preceding meanings. If Z has the meaning O, the chain extension agent of general formula

(6) may also be caused to react before the reaction in the second stage, with the diisocyanate of general formula (5) . Where appropriate, water may be used as chain extension agent.

Examples of diisocyanates of general formula (5) to be used are aliphatic compounds such as isophorone- diisocyanate, hexamethylene-1 , 6 -diisocyanate, tetra- methylene-1 , 4 -diisocyanate and methylenedicyclohexyl- 4 , 4 ' -diisocyanate or aromatic compounds such as methylenediphenyl-4 , 4 ' -diisocyanate, 2 , 4-toluenediiso- cyanate, 2 , 5-toluenediisocyanate, 2 , 6-toluenediiso- cyanate, m-phenylenediisocyanate, p-phenylenediiso- cyanate, m-xylenediisocyanate, tetramethyl-m-xylene- diisocyanate or mixtures of these isocyanates. One example of a commercially available compound is a diisocyanate of the DESMODUR ® series (H, I, M, T, W) from Bayer AG, Germany. Aliphatic diisocyanates are preferred in which Y is an alkylene radical because they lead to materials which exhibit improved stability to UV.

The alkylenes with α,ω-0H ends of general formula (6) are preferably polyalkylenes or polyoxyalkylenes . These are preferably essentially free of contaminations of polyoxyalkylenes that are mono- or trifunctional or that have a higher functionality. It is possible to use here polyether polyols, polytetramethylene diols, polyester polyols, polycaprolactone diols, but also polyalkylenes with α,ω-0H ends based on poly (vinyl acetate), poly(vinyl acetate) -ethylene copolymers, poly (vinyl chloride) copolymers, polyisobutylene diols. Preferably, use is made of polyoxyalkylenes, in a particularly preferred manner, of polypropylene glycols. Such compounds are commercially available as base materials among others, for polyurethane foams and for uses such as coating, with molecular masses Mn of up to 10 000. Examples are the polyether polyols and

polyester polyols BAYCOLL ® from Bayer AG, Germany or the polyether polyols Acclaim ® from Lyondell Inc., USA. Use may also be made of α, ω-alkylenediol monomers, such as ethylene glycol, propanediol, butanediol or hexanediol . On the other hand, the expression dihydroxylated compounds, for the purposes of the invention, is also understood to mean bishydroxyalkylsilicones, as provided for example by the company Goldschmidt under the names Tegomer H-Si 2111, 2311 and 2711.

The preparation of the copolymers described above of general formula (I) may be carried out in solution, but also in solid form, continuously or batchwise.

If the quantity of urethane or urea segments is high, a solvent is chosen which has a high solubility parameter, such as for example dimethylacetamide . THF may also be used. According to a particular embodiment, the synthesis of the copolymer is carried out without solvent . The synthesis is preferably carried out in the absence of moisture and under a protective gas, usually nitrogen or argon.

The reaction is preferably carried out in the presence of a catalyst. The catalysts appropriate for the preparation are dialkyltin compounds, such as for example dibutyltin dilaurate, dibutyltin diacetate, or tertiary amines such as for example N, N-dimethylcyclo- hexanamine, 2-dimethylaminoethanol , 4-dimethylamino- pyridine. According to a particular embodiment, the copolymer used in the present invention does not contain polyurethane .

By way of example of copolymer, there may be mentioned the dimethylpolysiloxane/urea copolymer, with the INCI name polyureadimethicone .

Such a polymer may be obtained in particular by copolymerization of an alpha, omega-aminosilicone with a diisocyanate . Polymers corresponding to these characteristics are for example the products marketed

The wax considered in the context of the present invention is in general a lipophilic compound, which is solid at room temperature (25 0 C) , which exhibits a reversible solid/liquid change of state, and which has a melting point greater than or equal to 3O 0 C which may range up to 200 0 C and in particular up to 12O 0 C.

Upon bringing the wax to the liquid state (melting) , it is possible to make it miscible with oils and to form a microscopically homogeneous mixture, but on bringing the temperature of the mixture back to room temperature, recrystallization of the wax from the oils of the mixture is obtained.

In particular, the waxes suitable for the invention may have a melting point greater than or equal to 45 0 C, and in particular greater than or equal to 55 0 C. For the purposes of the invention, the melting temperature corresponds to the temperature of the most endothermic peak observed by thermal analysis (DSC) as described in the ISO standard 11357-3; 1999. The melting point of the wax may be measured with the aid of a differential scanning calorimeter (DSC) , for example the calorimeter sold under the name "MDSC 2920" by the company TA Instruments.

The measurement protocol is the following:

A sample of 5 mg of wax placed in a crucible is subjected to a first rise in temperature ranging from -2O 0 C to 100 0 C, at the heating rate of 10°C/minute, and is then cooled from 100 0 C to -2O 0 C at a cooling rate of 10°C/minute and finally subjected to a second rise in temperature ranging from -2O 0 C to 100 0 C at a heating rate of 5°C/minute. During the second temperature rise, the variation of the difference in power absorbed by the empty crucible and by the crucible containing the wax sample is measured as a function of the temperature. The melting point of the compound is the temperature value corresponding to the summit of the peak of the curve representing the variation of the difference in power absorbed as a function of the temperature .

The waxes which can be used in the compositions according to the invention are chosen from waxes that are solid at room temperature, of animal, plant, mineral or synthetic origin, and mixtures thereof.

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

The hardness is determined by measuring the compression force, measured at 2O 0 C, with the aid of the texturometer sold under the name TA-XT2 by the

company RHEO, equipped with a stainless steel cylinder having a diameter of 2 mm, moving at the measurement speed of 0.1 mm/s, and penetrating into the wax to a penetration depth of 0.3 mm. The measurement protocol is the following:

The wax is melted at a temperature equal to the melting point of the wax +1O 0 C. The molten wax is poured into a vessel having a diameter of 25 mm and a depth of 20 mm. The wax is recrystallized at room temperature (25 0 C) for 24 hours such that the surface of the wax is flat and smooth, and then the wax is stored for at least 1 hour at 2O 0 C before carrying out the measurement of the hardness or of the tack.

The texturometer spindle is moved at the speed of 0.1 mm/s, and then penetrates into the wax to a penetration depth of 0.3 mm. When the spindle has penetrated into the wax to the depth of 0.3 mm, the spindle is held still for 1 second (corresponding to the relaxation time) and is then withdrawn at a speed of 0.5 mm/s.

The value of the hardness is the measured maximum compression force divided by the surface area of the texturometer cylinder in contact with the wax.

By way of illustration of waxes suitable for the invention, there may be mentioned in particular hydrocarbon waxes such as beeswax, lanolin wax, Chinese wax; 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, paraffins and ozokerite; polyethylene waxes, the waxes obtained by Fisher- Tropsch synthesis and waxy copolymers and esters thereof .

22L73 ® by the company SOPHIM. Such waxes are described in application FR-A-2792190.

According to a particular embodiment, the compositions according to the invention may comprise at least one wax termed tacky wax, that is to say having a tack 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 may 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 ranging from 0.3 to 2 N.s.

The tack of the wax is determined by measuring the variation in the force (compression force) as a function of time, at 2O 0 C, according to the protocol indicated above for the hardness.

During the relaxation time of I s, the force

(compression force) decreases substantially until it becomes zero, and then, during the withdrawal of the spindle, the force (stretching force) becomes negative, and then increases again toward the value 0. The tack corresponds to the integral of the curve of the force as a function of time for the part of the curve corresponding to the negative values of the force. The tack value is expressed in N.s.

The tacky wax which may 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, in particular ranging from 0.05 MPa to 3 MPa.

As tacky wax, use may be made of a C 20 -C 40 alkyl (hydroxystearyloxy) stearate (the alkyl group comprising from 20 to 40 carbon atoms), alone or as a mixture.

Such a wax is in particular sold under the names "Kester Wax K 82 P ® " and "Kester Wax K 80 P ® " by the company KOSTER KEUNEN.

In the present invention, it is also possible to use waxes provided in the form of small particles having a size expressed as mean "effective" volume diameter D [4.3] of the order of 0.5 to 30 micrometres, in particular from 1 to 20 micrometres, and more particularly from 5 to 10 micrometres, designated in the text that follows by the expression "microwaxes" .

The size of the particles may be measured by various techniques; there may be mentioned in particular (dynamic and static) light scattering techniques, Coulter counter methods, sedimentation rate measurements (linked to size via Stoke' s 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 the compositions according to the invention are measured by static light scattering by means of a commercial granulometer of the MasterSizer 2000 type from Malvern. The data are processed on the basis of the Mie scattering theory. This theory, which is exact for isotropic particles, makes it possible to determine, in the case of nonspherical particles, an "effective" particle diameter. This theory is in particular described in the manual 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 mean "effective" volume diameter D[4.3] , defined in the following manner: ∑V. d, tfch-yy-

where V 1 represents the volume of the particles having an effective diameter Ci 1 . This parameter is in particular described in the technical documentation of the granulometer . The measurements are carried out at 25 0 C, on a dilute dispersion of particles, obtained from the composition in the following manner: 1) dilution by a factor of 100 with water, 2) homogenization of the solution, 3) allowing the solution to stand for 18 hours, 4) recovering the whitish homogeneous supernatant .

The "effective" diameter is obtained by taking a refractive index of 1.33 for water and a mean refractive index of 1.42 for the particles. As microwaxes which can be used in the compositions according to the invention, there may be mentioned in particular Carnauba microwaxes such as the one marketed under the name MicroCare 350 ® by the company MICRO POWDERS, the microwaxes of synthetic wax such as the one marketed under the name MicroEase 114S ® by the company MICRO POWDERS, the microwaxes constituted of a mixture of Carnauba wax and polyethylene wax such as those marketed under the names Micro Care 300 ® and 310 ® by the company MICRO POWDERS, the microwaxes constituted of a mixture of Carnauba wax and synthetic wax such as the one marketed under the name Micro Care 325 ® by the company MICRO POWDERS, the polyethylene microwaxes such as those marketed under the names Micropoly 200 ® , 220 ® , 220L ® and 250S ® by the company MICRO POWDERS and the polytetrafluoroethylene microwaxes such as those marketed under the names Microslip 519 ® and 519 L ® by the company MICRO POWDERS.

The composition according to the invention may comprise a content of waxes ranging from 5 to 70% by weight relative to the total weight of the composition, in particular it may contain from 7 to 50%, more particularly from 10 to 45% thereof. Semicrystalline polymers

The expression polymer is understood to mean

compounds containing at least two repeating units, preferably at least 3 repeating units and more especially at least 10 repeating units. The expression "semicrystalline polymer" is understood to mean polymers containing a crystallizable part, a crystal- lizable pendent chain or a crystallizable block in the backbone, and an amorphous part in a backbone and having a first order reversible phase transition temperature, in particular of melting (solid-liquid transition) . When the crystallizable part is in the form of a crystallizable block of the polymer backbone, the amorphous part of the polymer is in the form of an amorphous block; the semicrystalline polymer is in this case a block copolymer, for example of the diblock, triblock or multiblock type, containing at least one crystallizable block and at least one amorphous block. The expression "block" is generally understood to mean at least 5 identical repeating units. The crystallizable block (s) are in this case of a chemical nature different from the amorphous block (s) .

The semicrystalline polymer has a melting temperature greater than or equal to 3O 0 C (in particular ranging from 3O 0 C to 8O 0 C) , preferably ranging from 3O 0 C to 6O 0 C. This melting temperature is a first order change of state temperature.

This melting temperature may be measured by any known method and in particular with the aid of a differential scanning calorimeter (D. S. C) .

Advantageously, the semicrystalline polymer (s) to which the invention applies have a number-average molecular mass greater than or equal to 1000. Advantageously, the semicrystalline polymer (s) of the composition of the invention have a number-average molecular mass Mn ranging from 2000 to 800 000, preferably from 3000 to 500 000, even better from 4000 to 150 000, in particular less than 100 000, and even better from 4000 to 99 000. Preferably, they have a number-average molecular mass greater than 5600, ranging for example from 5700 to 99 000. The expression

"crystallizable chain or block" is understood to mean, for the purposes of the invention, a chain or block which, if it were alone, would pass from the amorphous state to the crystalline state, reversibly, according to whether the temperature is above or below the melting temperature. A chain, for the purposes of the invention, is a group of pendent or side atoms relative to the polymer backbone. A block is a group of atoms belonging to the backbone, a group constituting one of the repeating units of the polymer. Advantageously, the "crystallizable pendent chain" may be a chain containing at least 6 carbon atoms .
