The subject of the present invention is a device that is suitable for applying a cosmetic composition in the form of a liquid emulsion comprising a particular film-forming polymer, the composition, and also a process for making up and/or caring for the lips in particular using the device and the composition.

The present invention relates to the field of making up and/or caring for the lips using fluid compositions.

The development of fluid compositions dedicated to making up and/or caring for the lips, such as liquid lipsticks, which are stable and endowed with satisfactory properties in terms of application (guidance on application, ease of spreading and fineness of the deposit), but also in terms of the makeup effect of the deposit on the lips, for instance the coverage and the absence of migration of the deposit, preferably without becoming tacky, is an ongoing objective.

Generally, formulations corresponding to anhydrous liquid galenical formulations conventionally comprise oils, which in particular provide gloss, optionally waxes for structuring the compositions, fillers, in particular for thickening the composition, film-forming polymers, and colorants.

In the more particular case of compositions providing coverage, it is important for the latter to be easy to apply to the lips, precisely and as an even layer. In addition, the deposit is not expected to migrate, which would result in the outline of the lips being made imprecise.

With the conventional lipstick compositions of this type, generally used with dipping applicators which have a flocked end piece, it is noted that the deposit is relatively thick, thereby giving it a more or less tacky nature, in particular induced by the use of these oils and of the polymers present. This nature is in particular reflected by a phenomenon of the made up lips sticking to one another, which is therefore unpleasant in terms of comfort for the user.

Another difficulty encountered with liquid lipsticks lies in the fact that the composition must be sufficiently fluid to be easily applied, but not too fluid, so as to avoid losing stability of the composition (pigment sedimentation) and losing ease of application (running and/or migration of the composition to the wrinkles and fine lines of the area around the lips).

Compositions which at the same time provide very good coverage of the lips, as a precise deposit, which does not migrate, and for which the tacky nature has been virtually dispensed with, and a device which would make it possible to apply them, are therefore sought.

These objectives are achieved by means of the present invention, a subject of which is thus a device for packaging a cosmetic composition (P) and applying it to the lips, comprising:

-on the one hand, a body forming a reservoir which is intended to contain the cosmetic composition (P) to be applied, -and, on the other hand, an applicator comprising an applicator member defining a convex application surface having at least one apex; the body forming a reservoir comprising a housing capable of receiving the applicator member and of which a dividing wall with the reservoir has at least one through-orifice in direct fluid communication with the reservoir, said orifices being located only at at least one base of the housing opposite the vicinity of an apex of the applicator member when said applicator member is in place in the housing of the body forming a reservoir:

-the applicator member is made from an open-cell porous material;

-the applicator is configured so as to fit onto the container when not in use, the applicator member being received in the housing; the applicator makes it possible to close the reservoir;

-the cosmetic composition (P) which is in the form of a liquid emulsion comprising:

o water;

o at least one film-forming agent chosen from vinyl polymers comprising at least one carbosiloxane dendrimer-based unit;

o at least one polar non-volatile hydrocarbon-based oil;

o at least one non-volatile phenyl silicone oil, preferably without dimethicone fragment.

The invention also relates to a cosmetic composition which is in the form of a liquid emulsion comprising:

o water;

o at least one film-forming agent chosen from vinyl polymers comprising at least one carbosiloxane dendrimer-based unit;

o from 5% to 15% by weight, relative to the weight of the composition, of at least one polar non-volatile hydrocarbon-based oil;

o from 1 % to 8% by weight, relative to the weight of the composition, of at least one non-volatile phenyl silicone oil, preferably without dimethicone fragment.

Furthermore, the invention relates to a process for making up and/or caring for the lips, in which the abovementioned composition is applied to the lips, in particular, by means of the abovementioned device.

Application devices that are particularly suited to this composition will be described with reference to the appended drawings, in which:

- Figure 1 is a diagrammatic representation in longitudinal section of a packaging and applying assembly according to the invention.

- Figure 2 is a diagrammatic representation in longitudinal section of an applicator member equipping the assembly of Figure 1.

- Figure 3 is a diagrammatic representation in longitudinal section of a ring forming a housing for the applicator member of Figure 2.

- Figure 4 is a diagrammatic representation viewed from above of the ring of Figure 3. The film deposited on the lips has the advantage of being very thin and of being virtually imperceptible to the user. It is thus a very light deposit that is deposited on the lips by means of the device which is the subject of the invention. This deposit is also non-tacky, and does not introduce a sensation of dryness. The deposit thus obtained does not migrate, does not transfer, and has a very good wear property.

It should be noted that, in the remainder of the description, unless otherwise indicated, the limits indicated for a range are included in that range.

The contents are indicated relative to the weight of the composition, in other words, relative to the weight of the total composition.

The expressions "at least one" and "several" are used without distinction.

DEVICE

The present invention thus relates to a device for packaging and applying a liquid cosmetic composition.

This device is in particular described in French Patent applications n° 1559092 filed on 25/09/15 and n° 1651670 filed on 29/02/16.

More particularly, the device in accordance with the present invention comprises, on the one hand, a body forming a reservoir intended to contain the cosmetic composition to be applied and, on the other hand, an applicator comprising an applicator member defining a convex application surface having at least one apex.

The body forming a reservoir comprises a housing capable of receiving the applicator member and of which one dividing wall with the reservoir has at least one through-orifice in direct fluid communication with the reservoir. Said orifices are located only at at least one base of the housing opposite the vicinity of an apex of the applicator member when said applicator member is in place in the housing of the body forming a reservoir.

The packaging and applying assembly is characterized in that the applicator member is made from an open-cell porous material.

The presence of an applicator member defining a convex application surface having an apex or a tip allows in particular a precise application of the composition.

The orifices made in the wall of the housing for receiving the applicator member make it possible in particular to load the applicator member with composition, in particular when the reservoir is shaken or turned upside down.

The expression "orifice located only at at least one base of the housing" is intended to mean that the remainder of the dividing wall is solid, that is to say not pierced.

Thus, when combining one or more distribution orifices in direct fluid communication, arranged in a very localized manner with a porous application surface, it has been noted, surprisingly, that the packaging and applying assembly targeted allows a precise, comfortable and uniform application of the cosmetic product contained in the reservoir.

The use of very localized orifices also makes it possible to limit the passing of the composition through the dividing wall and thus to obtain a precise and sufficient dose of composition, without overloading the applicator, consequently making it possible to obtain a thin deposit.

The remainder of the application surface, in particular a peripheral or side zone, can be used to tone down the composition applied and to refine the make-up.

The term "direct fluid communication" is intended to mean that the orifice is not linked to a distributing means with a selected opening of the pump or aerosol type making it possible to force the cosmetic composition to pass through said orifice. The loading of the applicator member is done by simply shaking the reservoir or turning it upside down.

This does not prevent the use of a selective closure mechanism making it possible in particular to ensure that the reservoir is leak tight when it is not used, the passage of the composition through the orifice remaining unforced.

In the present application, the expression "vicinity of an apex of the applicator member" targets an apex portion extending in the vicinity of the isolated geometric apex. It may be considered that the orifices are located in a zone around the geometric apex representing at most 5% or even 10 % of the total surface area of the application surface.

Preferentially, the orifices are located at a base of the housing corresponding to an absolute apex of the applicator member, preferably only at said base.

According to a first implementation variant, the wall of the housing has a single orifice. According to a second implementation variant, the wall of the housing has a plurality of orifices.

The presence of a plurality of orifices makes it possible to retain orifices of relatively small size, making it possible to ensure the passage of the most homogeneous possible amount of composition while at the same time ensuring a total passage surface area is sufficient for good loading of the applicator member, after for example only a few shaking movements. In addition, the size of the orifices is also determined according to the size of the solid particles so as to prevent or limit blocking phenomena.

In the case of several orifices, the latter are preferentially distributed uniformly around the centre of the base. This makes it possible to ensure optimal loading of the application tip.

Advantageously, additionally, the wall of the housing has a central orifice, located at the centre of the base. The term "centre of the base" is intended to mean the tip opposite the geometric apex of the applicator.

According to one preferred embodiment, all or some of the orifices have a substantially circular cross section. Such a circular-shaped cross section is very suitable for preventing blocking phenomena. Where appropriate, depending on the particles used, other cross sections can be envisaged.

Advantageously additionally, the reservoir comprises at least one mixing element, in particular at least one mixing bead. The characteristics of the mixing element, such as the weight or the size, will be chosen according to the properties of the cosmetic composition.

The applicator member can preferably be made of a foam, it is preferentially a block of foam. Preferentially, the applicator member has an application surface that is at least partially flocked, preferably totally flocked.

According to one variant which is not represented, the support and fixing system comprises at least one complementary clamping ring capable of compressing a part of the mounting foot located at a non-zero distance from a base surface of said mounting foot oriented towards the base wall of the support and fixing system when the applicator member is placed in the housing of the support and fixing system, the clamping ring having at least one clip-fastening means capable of cooperating with at least one complementary clip- fastening means of the peripheral skirt of the support and fixing system.

The clamping ring can be made dismountable so as to optionally allow the applicator member to be replaced with an identical, for example new, or different applicator member.

Moreover, said clamping ring compresses only one part of the mounting foot of the applicator member at a distance from a base of said mounting foot. It follows that the mounting foot has a compressed portion, of reduced cross section, and a base portion which is non-compressed or less compressed, having a greater cross section. The non- compressed or less compressed base portion has a wider cross section which opposes any extraction movement in a longitudinal component, including side travel movements, of the applicator member outside the ring and greatly contributes to the fixing thereof and the holding in place thereof. In addition, the compression of a part of the mounting foot of the applicator member increases the friction between the mounting foot and the ring, thereby also contributing to the overall holding in place.

Advantageously, the degree of compression is at least 10%, preferably at least 20%, or even at least 30%, relative to the cross section of the applicator member in the non- compressed or less compressed state in the housing, and preferably less than 40%, or even 35%.

Additionally advantageously, the base wall of the support and fixing system comprises at least one notch capable of penetrating into the base surface of the foot of the applicator member. The notches contribute to the fixing of the applicator member by limiting side movements, in particular rotation movements.

Additionally advantageously, said clamping ring has an end, preferentially intended to be oriented towards the base wall of the support and fixing system, said end having an at least partially peripheral radial shoulder capable of cooperating with a complementary at least partially peripheral groove of the mounting foot of the applicator member.

Preferentially, the peripheral radial shoulder has a surface intended to be oriented towards the base wall of the support and fixing system and which has at least one attaching notch capable of penetrating into a corresponding surface of the peripheral groove of the applicator member.

According to one preferred embodiment the groove of the mounting foot of the applicator member is located substantially half way up said mounting foot, more particularly between 30% and 60% of the height of said mounting foot relative to its base. Additionally, the base wall of the support and fixing system has at least one pin, not represented, which is in particular central, extending substantially perpendicular to the base wall at least partially through the clamping ring and capable of penetrating into a corresponding cavity of the mounting foot of the applicator member.

Preferentially, the pin extends over the entire length of the clamping ring and totally passes through it.

Preferentially, the pin of the base wall juts out from the skirt of the support and fixing system. Such a characteristic helps to limit the amplitude of travel of the applicator member.

Advantageously, the clamping ring extends over approximately half the height of the mounting foot of the applicator member. Preferentially, the clamping ring extends over at least 40% of the height of the mounting foot and over at most 90% of the height of the mounting foot.

Advantageously, the applicator is configured so as to fix onto the container when not in use, the applicator member being received in the housing. Thus, the applicator makes it possible to close the reservoir.

Preferentially, the application surface exhibits no surface in particular no concavity, capable of forming a space with the wall of the housing when the applicator member is received in the housing. In particular, the application surface exhibits no concavity in comparison with the orifices. This is because the presence of a concavity could be capable of causing the formation of a cavity between the applicator and the dividing wall of the housing, inside of which cavity product could accumulate, which is not desirable.

Preferably, the applicator member has a conical general shape, in particular with a rounded tip, or hemispherical general shape. Such a shape is particularly suitable for an application to the lips.

More preferably, the orifices are blocked by the application surface when the applicator is fixed onto the container. This makes it possible to prevent any leaking of the cosmetic composition through the orifices when the applicator is in the closed position.

Additionally advantageously, the application surface at least partially deforms against the wall of the housing when the applicator is fixed onto the container, the applicator member being slightly compressed. Thus, it is possible, depending on the characteristics of the cosmetic composition, to place the applicator member under slight compression in order to add a pump effect making it possible to facilitate the diffusion of the composition. This compression also improves the blocking of the orifices by the applicator member.

The present invention will be understood more clearly on reading the detailed description which follows, from the viewpoint of the appended drawings in which:

- Figure 1 is a diagrammatic representation in longitudinal section of a packaging and applying assembly according to the invention.

- Figure 2 is a diagrammatic representation in longitudinal section of an applicator member equipping the assembly of Figure 1.

- Figure 3 is a diagrammatic representation in longitudinal section of a ring forming a housing for the applicator member of Figure 2. - Figure 4 is a diagrammatic representation viewed from above of the ring in Figure

3.

Figure 1 shows an assembly 1 for packaging and applying the cosmetic composition P.

The assembly 1 comprises a body 2 forming a reservoir 3 containing the cosmetic composition P to be applied and an applicator 4 comprising an applicator member 5 defining a convex application surface 50 having at least one apex 51 .

The body 2 has a free upper edge 21 delimiting an opening 22 of said reservoir 3. More specifically, the opening 22 is located at a free upper end of a collar 24 of the body 2.

The body 2 has a symmetry of rotation. The opening 22 has a circular cross section. Of course, other shapes can be envisaged.

The body 2 has, at the opening 22, a housing 7 capable of receiving the applicator member 5, said housing 7 being at least partially delimited by a dividing wall 8 of the reservoir 3.

In accordance with the present application, the dividing wall 8 has at least one through- orifice 9 in direct fluid communication with the reservoir 3.

The dividing wall 8 can be attached to the reservoir 3, as illustrated, or can be made of a single part by moulding the body of the reservoir.

In the case in point, the dividing wall 8 is borne by a ring 60 surmounting the opening

22.

The ring 60 may be mounted on the body 2 by any means, in particular by clip- fastening or adhesive bonding. It may be removable or non-removable.

In the case in point, the ring 60 is capable of coming into contact with the collar 24.

To do this, the ring 60 comprises an external peripheral wall 61 and an internal peripheral wall 62 together defining a mounting skirt.

The mounting skirt also ensures leak tightness with respect to the product.

Alternatively, a ring as represented in Figure 10J of document FR 296 2890 can also be envisaged.

The applicator 4 exceptionally comprises a grasping part 41 on which the applicator member 5 is mounted.

The grasping part 41 forms a cap and is capable of coming into contact, in a removable manner, with an upper peripheral wall 63 of the ring 6, thus sealing the reservoir 3 closed. More particularly, the peripheral wall 63 of the ring 6 bears an external male screw thread 64 capable of cooperating with a complementary internal tapped thread 65 of the grasping part.

When not in use, and when the grasping part 41 is screwed onto the ring 6, the applicator member 5 is received in the housing 7 (Figure 1 ).

In accordance with the present application, the applicator member 5 is made of an open-porosity porous material, for example of a foam.

In particular, the applicator member 5 is made of a polyurethane foam, in particular of S90 type (standard DIN 4102-9).

The applicator member 5 is mounted on the grasping part 41 by any known means, in particular by assembly, clip-fastening or snap-fastening. In the case in point, the applicator member 5 has a substantially cylindrical foot 55 which is introduced into a corresponding pillar 42 of the grasping part. A base wall 43 of the pillar 42 increases the fixing surface. The base wall 43 also provides translational blocking.

Opposite the foot 55, the applicator member 5 has a head 56 defining the application surface 51 . The head 56 has a generally conical shape. The head 56 has a rounded free end or point forming the apex 51 . In the case in point, the apex 51 is consequently an absolute apex.

The head 56 has a base which has a diameter that is slightly larger than the diameter of the foot 55 and thus has a shoulder 54 capable of bearing against an edge of the pillar 42. This shoulder 57 makes it possible in particular to give the applicator member better strength.

The housing 7 is conformed so as to have a shape substantially complementary to the head 56.

As can be seen in Figure 1 , when the applicator 4 is fixed onto the reservoir 3 and the applicator member 5 is in place in the housing, the apex 51 is slightly compressed.

It will also be noted that the application surface 51 is flocked. For the application of the flock, use may be made of an adhesive that is relatively rigid after drying. Thus, drying the adhesive contributes to making the applicator member 5 rigid.

As previously indicated, the housing 7 is in communication with the interior of the reservoir 3 by means of the perforated dividing wall 8, passing through which are orifices 9 that are constantly open.

In accordance with the present application, the orifices 9 are located only at at least one base of the housing in comparison to the vicinity of the apex 51 of the applicator member 5 when said applicator member 5 is placed in the housing 7 of the body 2 forming a reservoir 3.

In the case in point, the wall 8 comprises three orifices 9. The orifices 9 are regularly distributed in proximity to and around the centre of the base of the wall 8. The orifices have substantially circular cross section. In the case in point, the diameter of the orifices is 1 .5 mm.

The total surface area of the orifice(s) is thus approximately 5.3 mm ² . Preferably, the total surface area of the openings is less than 5.5 mm ² . The total surface area of each opening is also sufficient to limit or even prevent blocking phenomena.

The centre of each orifice 9 is located at a distance of 4.5 mm from the centre of the base corresponding to the apex 51 of the applicator member. Preferably, the orifices are located at less than 5 mm from the centre of the base.

The applicator member 5 advantageously blocks all the orifices of the wall 8 when the applicator 4 is in place on the reservoir 3. This can be useful for preventing any excess composition from spilling in the housing when the applicator closes said housing.

Advantageously, the reservoir 3 comprises at least one mixing element, in particular at least one mixing bead (not represented).

The packaging and applying assembly 1 is used in the following way. Since the assembly 1 is in closed configuration, the user can shake the assembly or turn it upside down.

In doing so, product is projected through the orifices 9 of the dividing wall 8 and very locally impregnates the applicator member 5 at an apex 51 of its application surface.

After a few shaking movements, the user unscrews the applicator 4 and grasps said applicator 4 by the grasping part 41 and disconnects it from the reservoir 3. In doing so, the applicator member 5 is extracted from the housing 7 and the application surface is accessible to the user who can then carry out the application.

To do this, the user brings the apex portion of the applicator member into contact with the application surface to be covered, for example a surface of the lips, so as to deposit thereon the cosmetic composition.

Where appropriate, said user can use a side portion of the application surface to tone down or spread the composition. COMPOSITION

As indicated previously, the composition, particularly used in the device that has just been described, is in the form of a liquid emulsion.

The term "liquid" is intended to mean a fluid texture, the viscosity of which at 25°C is more particularly between 0.005 and 12 Pa.s, preferably between 0.01 and 10 Pa.s and even more advantageously between 0.05 and 8 Pa.s.

Preferably, the viscosity at 25°C of a composition according to the invention is between 0.1 and 6 Pa.s. Protocol for measuring the viscosity:

The viscosity measurement is generally performed at 25°C, using a Rheomat RM180 viscometer equipped with a No. 2 or 3 spindle, the measurement being performed after 10 minutes of rotation of the spindle in the formula, at a shear rate of 200 revolutions/min (rpm).

The composition may be in the form of a direct (oil-in-water) or inverse (water-in-oil) emulsion.

According to one preferred embodiment of the invention, the composition is in the form of an inverse (water-in-oil) emulsion.

Moreover, the composition according to the invention comprises, in addition to the water, at least one particular film-forming polymer and at least non-volatile oils, one of which is chosen from polar hydrocarbon-based non-volatile oils, the other of which is chosen from phenyl silicone non-volatile oils, preferably free of dimethicone fragment.

The composition according to the invention could also comprise other additional non- polar hydrocarbon-based or non-phenyl silcone non-volatile oils.

The total content of non-volatile oils preferably represents from 6 to 20% by weight, and in accordance with an even more particular embodiment, from 6 to 15% by weight, relative to the weight of the composition. POLAR NON-VOLATILE HYDROCARBON-BASED OILS

As previously indicated, the composition used in the device in accordance with the invention comprises at least one polar non-volatile hydrocarbon-based oil.

The term "oil" is intended to mean a water-immiscible non-aqueous compound which is liquid at 25°C and atmospheric pressure (1.013 x 10 ⁵ Pa).

The term "immiscible" is intended to mean that the mixing of the same amount of water and oil, after stirring, does not result in a stable solution comprising only a single phase, under the above-mentioned temperature and pressure conditions. Observation is carried out by eye or using a phase contrast microscope, if necessary, on 100 g of mixture obtained after sufficient Rayneri stirring to produce a vortex within the mixture (by way of indication, 200 to 1000 rev/min), the resulting mixture being left standing, in a closed flask, for 24 hours at ambient temperature before observation.

The term "non-volatile oil" is intended to mean an oil of which the vapour pressure at

25°C and atmospheric pressure is non-zero and is less than 10 ^"3 mmHg (0.13 Pa).

The term "hydrocarbon-based oil" is intended to mean an oil formed essentially from, or even constituted of, carbon and hydrogen atoms, and optionally oxygen and nitrogen atoms, and not containing any silicon or fluorine atoms.

It can contain alcohol, ester, ether, carboxylic acid, amine and/or amide groups.

Preferably, the hydrocarbon-based oil is, in addition to being free of silicon and fluorine, free of heteroatoms such as nitrogen, sulfur and phosphorus. The hydrocarbon-based oil is thus distinct from a silicone oil and a fluorinated oil.

In the present case, the polar non-volatile hydrocarbon-based oil comprises at least one oxygen atom.

In particular, this non-volatile hydrocarbon-based oil comprises at least one alcohol function (it is then an "alcohol oil") and/or at least one ester function (it is then an "ester oil").

The ester oils that may be used in the compositions according to the invention may in particular be hydroxylated.

The composition according to the invention may comprise one or more non-volatile hydrocarbon-based oils, in particular chosen from:

- C n-CpR alcohols, preferably monoalcohols;

More particularly, the Ci ₀ -C ₂ 6 alcohols are saturated or unsaturated and branched or unbranched and comprise from 10 to 26 carbon atoms.

Preferably, the Ci ₀ -C ₂ 6 alcohols are fatty alcohols, which are preferably branched when they comprise at least 16 carbon atoms.

As examples of fatty alcohols that may be used according to the invention, mention may be made of linear or branched fatty alcohols, of synthetic origin or alternatively of natural origin, for instance alcohols derived from plant materials (coconut, palm kernel, palm, etc.) or animal materials (tallow, etc.). Needless to say, other long-chain alcohols may also be used, for instance ether alcohols or alternatively "Guerbet" alcohols.

Finally, use may also be made of certain fractions of alcohols of varying length of natural origin, for instance coconut (Ci ₂ to Ci ₆ ) or tallow (Ci ₆ to Ci ₈ ) or compounds of diol or cholesterol type.

Preferably, a fatty alcohol comprising from 10 to 24 carbon atoms is used.

Mention may in particular be made, as specific examples of fatty alcohols which can preferably be used, of lauryl alcohol, isostearyl alcohol, oleyl alcohol, 2-butyloctanol, 2- undecylpentadecanol, 2-hexyldecyl alcohol, isocetyl alcohol, octyldodecanol and mixtures thereof.

The vinyl polymer comprising the carbosiloxane dendrimer according to the invention can be manufactured according to the process for manufacturing a branched silalkylene siloxane described in Japanese Patent Application Hei 9-171 154.

To facilitate the preparation of starting material for cosmetic products, the number- average molecular weight of the vinyl polymer which comprises a carbosiloxane dendrimer can be chosen within the range between 3000 and 2 000 000 g/mol and preferably between 5000 and 800 000 g/mol. It can be a liquid, a gum, a paste, a solid, a powder or any other form. The preferred forms are solutions formed by the dilution of a dispersion or of a powder in solvents.

The vinyl polymer can be a dispersion of a polymer of vinyl type having a carbosiloxane dendrimer structure in its molecular side chain, in a liquid such as a silicone oil, an organic oil, an alcohol or water.

The silicone oil can be a dimethylpolysiloxane having the two molecular ends capped with trimethylsiloxy groups, a copolymer of methylphenylsiloxane and of dimethylsiloxane having the two molecular ends capped with trimethylsiloxy groups, a copolymer of methyl(3,3,3-trifluoropropyl)siloxane and of dimethylsiloxane having the two molecular ends capped with trimethylsiloxy groups, or analogous unreactive linear silicone oils, and also hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane or an analogous cyclic compound. In addition to the unreactive silicone oils, modified polysiloxanes containing functional groups such as silanol groups, amino groups and polyether groups on the ends or within the molecular side chains may be used.

The organic oils can be isododecane, liquid paraffin, isoparaffin, hexyl laurate, isopropyl myristate, myristyl myristate, cetyl myristate, 2-octyldodecyl myristate; isopropyl palmitate, 2-ethylhexyl palmitate, butyl stearate, decyl oleate, 2-octyldodecyl oleate, myristyl lactate, cetyl lactate, lanolin acetate, stearyl alcohol, cetostearyl alcohol, oleyl alcohol, avocado oil, almond oil, olive oil, cocoa oil, jojoba oil, gum oil, sunflower oil, soybean oil, camelia oil, squalane, castor oil, cottonseed oil, coconut oil, egg yolk oil, polypropylene glycol monooleate, neopentyl glycol 2-ethylhexanoate or an analogous glycol ester oil; triglyceryl isostearate, the triglyceride of a fatty acid of coconut oil, or an analogous oil of a polyhydric alcohol ester; polyoxyethylene lauryl ether, polyoxypropylene cetyl ether or an analogous polyoxyalkylene ether.

The alcohol may be any type that is suitable for use in combination with a cosmetic product starting material. For example, it can be methanol, ethanol, butanol, isopropanol or lower alcohol analogues.

A solution or a dispersion of the alcohol should have a viscosity within the range from 10 to 10 ⁹ mPa at 25°C. To improve the sensory use properties in a cosmetic product, the viscosity should be within the range from 100 to 5 x 10 ⁸ mPa.s.

The solutions and dispersions can be easily prepared by mixing a vinyl polymer having at least one unit derived from carbosiloxane dendrimer with a silicone oil, an organic oil, an alcohol or water. The liquids can be present in the polymerization stage. In this case, the unreacted residual vinyl monomer should be completely removed by heat treatment of the solution or dispersion under atmospheric pressure or reduced pressure.

In the case of a dispersion, the dispersity of the polymer of vinyl type can be improved by adding a surfactant.

Such a surfactant can be hexylbenzenesulfonic acid, octylbenzenesulfonic acid, decylbenzenesulfonic acid, dodecylbenzenesulfonic acid, cetylbenzenesulfonic acid, myristylbenzenesulfonic acid or anionic surfactants of the sodium salts of these acids; octyltrimethylammonium hydroxide, dodecyltrimethylammonium hydroxide, hexadecyltrimethylammonium hydroxide, octyldimethylbenzylammonium hydroxide, decyldimethylbenzylammonium hydroxide, dioctadecyldimethylammonium hydroxide, (beef tallow)trimethylammonium hydroxide, (coconut oil)trimethylammonium hydroxide, or an analogous cationic surfactant; a polyoxyalkylene alkyl ether, a polyoxyalkylene alkylphenol, a polyoxyalkylene alkyl ester, the sorbitol ester of polyoxyalkylene, polyethylene glycol, polypropylene glycol, an ethylene oxide additive of diethylene glycol trimethylnonanol, and non-ionic surfactants of polyester type, and also mixtures.

In the dispersion, a mean particle diameter of the polymer of vinyl type can be within a range of between 0.001 and 100 microns and preferably between 0.01 and 50 microns. The reason for this is that, outside the recommended range, a cosmetic product mixed with the emulsion will not have a nice enough feel on the lips or to the touch, nor sufficient spreading properties nor a pleasant feel.

A vinyl polymer contained in the dispersion or the solution may have a concentration in the range between 0.1 % and 95% by weight and preferably between 5% and 85% by weight. However, to facilitate the handling and the preparation of the mixture, the range should preferably be between 10% and 75% by weight.

A vinyl polymer suitable for the invention can also be one of the polymers described in the examples of patent application EP 0 963 751 .

According to a preferred embodiment, a vinyl polymer grafted with a carbosiloxane dendrimer may be the product of polymerization of:

In the formula, the subscript "m" is 0 or 1 , "n" is 0, 1 , 2, 3, 4 or 5, and R ¹⁴ is a fluorine atom or CF ₃ .

The number-average molecular weight of the vinyl polymer used in the present invention may be between 3000 and 2 000 000 g/mol and more preferably between 5000 and 800 000 g/mol.

By way of hydrophobic thickeners, mention may most particularly be made of hydrophobic mineral thickeners such as modified clays, modified silicas, or mixtures thereof. Hydrophobic modified clays

Clays are silicates containing a cation which can be chosen from calcium, magnesium, aluminium, sodium, potassium or lithium cations, and mixtures thereof.

Mention may be made, as examples of such products, of clays of the family of the smectites, and also of the family of the vermiculites, stevensite or chlorites. These clays may be of natural or synthetic origin.

Preferably, use is made of organophilic clays, more particularly of modified clays, such as montmorillonite, bentonite, hectorite, attapulgite or sepiolite, and mixtures thereof. The clay is preferably a bentonite or a hectorite.

These clays are modified with a chemical compound chosen from quaternary amines, tertiary amines, amine acetates, imidazolines, amine soaps, fatty sulfates, alkylarylsulfonates or amine oxides, and mixtures thereof.

Mention may thus be made of hectorites modified by a quaternary amine, more specifically by a Cio to C22 fatty acid ammonium halide, such as chloride, comprising or not comprising an aromatic group, such as hectorite modified by a distearyldimethylammonium halide, preferably chloride (CTFA name: Disteardimonium hectorite), such as, for example, that sold under the name Bentone 38V, Bentone 38V CG or Bentone EW CE by Elementis, or stearalkonium hectorites, such as in particular the product Bentone 27 V.

Mention may also be made of quaternium-18 bentonites, such as those sold, inter alia, under the names Bentone 34 by the company Elementis, Claytone 40, Tixogel VP by the company United Catalyst by the company Southern Clay; stearalkonium bentonites, such as those sold under the names Tixogel LG by the company United Catalyst and Claytone AF and Claytone APA by the company Southern Clay; or quaternium-18/benzalkonium bentonites, such as those sold under the name Claytone HT by the company Southern Clay.

According to a preferred embodiment, the thickening agent is chosen from organophilic modified clays, in particular organophilic modified hectorites, in particular modified by benzyldimethylammonium stearate or distearyldimethylammonium halides, in particular chlorides. Modified silicas

Mention may also be made of fumed silica hydrophobically treated at the surface, the size of the particles of which is advantageously less than 1 μηη. This is because it is possible to chemically modify the surface of the silica, by chemical reaction generating a reduction in the number of silanol groups present at the surface of the silica. It is especially possible to substitute silanol groups with hydrophobic groups: a hydrophobic silica is then obtained. The hydrophobic groups may be:

- trimethylsiloxyl groups, which are obtained especially by treating fumed silica in the presence of hexamethyldisilazane. Silicas thus treated are known as Silica Silylate according to the CTFA (6th edition, 1995). They are sold, for example, under the references Aerosil R812 ^® by the company Degussa and Cab-O-Sil TS-530 ^® by the company Cabot, - dimethylsilyloxyl or polydimethylsiloxane groups, which are obtained especially by treating fumed silica in the presence of polydimethylsiloxane, for example hexamethyldisiloxane, or dimethyldichlorosilane. Silicas thus treated are known as Silica Dimethyl Silylate according to the CTFA (6th edition, 1995). They are sold, for example, under the references Aerosil R972 ^® and Aerosil R974 ^® by the company Degussa and Cab- O-Sil TS-610 ^® and Cab-O-Sil TS-720 ^® by the company Cabot.

The hydrophobic fumed silica in particular has a particle size that may be nanometric to micrometric, for example ranging from about 5 to 200 nm.

The composition according to the invention can also comprise at least silica aerogel particles.

Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air.

They are generally synthesized via a sol-gel process in a liquid medium and then dried, usually by extraction with a supercritical fluid, the one most commonly used being supercritical C0 ₂ . Drying of this type makes it possible to avoid contraction of the pores and of the material. The sol-gel process and the various drying operations are described in detail in Brinker C.J. and Scherer G.W., Sol-Gel Science, New York, Academic Press, 1990.

The hydrophobic silica aerogel particles suitable for the implementation of the invention exhibit a specific surface area per unit mass (S _M ) ranging from 500 to 1500 m ² /g, preferably from 600 to 1200 m ² /g and better still from 600 to 800 m ² /g, and a size, expressed as the volume-average diameter (D[0.5]), ranging from 1 to 1500 μηη, better still from 1 to 1000 μηη, preferably from 1 to 100 μηη, in particular from 1 to 30 μηη, more preferably from 5 to 25 μηη, better still from 5 to 20 μηη and even better still from 5 to 15 μηη.

According to an advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit mass (S _M ) ranging from

600 to 800 m ² /g and a size expressed as the volume-average diameter (D[0.5]) ranging from 5 to 20 μηη and even better still from 5 to 15 μηη.

The specific surface area per unit mass may be determined by the nitrogen absorption method, known as the BET (Brunauer-Emmett-Teller) method, described in The Journal of the American Chemical Society, vol. 60, page 309, February 1938 and corresponding to international standard ISO 5794/1 (annex D). The BET specific surface corresponds to the total specific surface of the particles under consideration.

The sizes of the silica aerogel particles can be measured by static light scattering using a commercial particle size analyser of 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 non-spherical particles, an "effective" particle diameter. This theory is in particular described in the publication by Van de Hulst, H.C., Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.

According to a preferred embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit of volume S _v ranging from 5 to 60 m ² /cm ³ , preferably from 10 to 50 m ² /cm ³ and better still from 15 to 40 m ² /cm ³ . The aerogels used according to the present invention are hydrophobic silica aerogels, preferably aerogels of silyl silica (I NCI name: silica silylate).

As regards the preparation of hydrophobic silica aerogel particles modified at the surface by silylation, reference may be made to the document US 7 470 725.

Use will preferably be made of hydrophobic silica aerogel particles modified at the surface by trimethylsilyl groups.

As hydrophobic silica aerogels that may be used in the invention, examples that may be mentioned include the aerogel sold under the name VM-2260 (I NCI name: Silica silylate), by the company Dow Corning, the particles of which have an average size of about 1000 microns and a specific surface area per unit mass ranging from 600 to 800 m ² /g.

Mention may also be made of the aerogels sold by Cabot under the references Aerogel TLD 201 , Aerogel OGD 201 , Aerogel TLD 203, Enova ^® Aerogel MT 1 100 and Enova Aerogel MT 1200.

Use will preferably be made of the aerogel sold under the name VM-2270 (I NCI name: Silica silylate) by the company Dow Corning, the particles of which have an average size ranging from 5-15 microns and a specific surface area per unit mass ranging from 600 to 800 m ² /g.

Preferably, the mineral thickeners are chosen from organophilic clays, in particular modified hectorites; hydrophobic treated fumed silica; hydrophobic silica aerogels, or mixtures thereof, and more specifically still at least one organophilic modified clay or at least one hydrophobic modified silica, in particular an organophilic modified clay.

More particularly, if the composition contains it (them), the content of mineral thickener(s) represents from 0.2% to 2.5% by weight, expressed as active material, and preferably from 0.5% to 2% by weight, relative to the weight of the composition.

The example hereinafter is given as a non-limiting illustration of the field of the invention.

EXAMPLE

1. Composition

The composition of which the ingredients are collated in the table below is prepared; the amounts are expressed in weight amount of starting material:

Composition Composition

Phase Ingredient

1 2

Cetyl PEG/PPG-10/1 Dimethicone (ABI L EM 90

3 3

A sold by Evonik Goldschmidt)

Polyglyceryl-4 Isostearate (Isolan GI34 sold by 1 1

2. Preparation

First of all, the pigments are mixed into a part of the dodecamethylpentasiloxane phase A (in an Exakt three-roll machine).

Separately, the aqueous phase D is prepared using a magnetic bar.

Separately, the ingredients of phase B are mixed by means of a Rayneri mixer. The ingredients of phase A, the pigments/ dodecamethylcyclopentasiloxane mixture previously obtained are then mixed, with Moritz stirring, for 20 minutes, at ambient temperature.

Once the mixture A is smooth and homogeneous and phase B is homogeneous, the emulsion is prepared at ambient temperature by pouring the aqueous phase D onto phase A, by means of a Moritz stirrer.

Once the mixing has been carried out, the stirring is continued until a homogeneous product is obtained and the whole mixture is packaged in a container fitted with a dip stirrer corresponding to Figure 1 .

The compositions obtained are homogeneous and stable. There is no release (for instance no apparition of a continuous or discontinuous layer of oil) or sedimentation, after treatment in the centrifuge (900 g for 1 hour).

After one week, they do not undergo any phase separation at room temperature or in an oven at 45°C (more particularly no release (i.e. no apparition of a continuous or discontinuous layer of oil), no sedimentation, no apparition of cracks in the composition).

The viscosity of composition 1 is 1 .4 Pa.s and the viscosity of composition 2 is 1.3 Pa.s (Rheomat 180 viscosimeter, spindle 3, 25°C; 10 minutes, 200rpm).

The device makes it possible to apply a very thin film to the lips, which is comfortable and which does not stick.

The composition applied does not migrate after one hour and the film wear is satisfactory. The film also has good wear.

It should be noted that, if a conventional applicator is used for lipgloss (for example a container fitted with a flocked flexible applicator of reference 14030, Geka GmbH), a thicker, stickier deposit is obtained, the resistance of which to migration and to transfer is not as good as when using the applicator according to the invention.

Protocol for measuring the film thickness:

This protocol is an in vitro measurement.

· A square of Bioskin ^® synthetic skin of 3 cm / 4 cm is prepared.

• The skin square obtained is weighed.

• The composition is applied by means of the device so as to obtain an even deposit covering the entire surface of the skin square.

• The skin square thus made-up is weighed.

Thickness of the film:

Thickness (cm) = volume of composition applied (g): density of the composition (g/cm ³ ). The density of the composition is 1.

The average thickness is given with three separate measurements.
