Description

LIPSTICK COMPOSITION IN EMULSION FORM COMPRISING A PARTICULAR FILM- FORMING POLYMER AND TREATMENT PROCESS EMPLOYING SAME

The subject of the present invention is a composition in the form of an emulsion comprising a particular film-forming polymer and also a process for making up and/or caring for the lips using same.

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 (glidance 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, the formulations corresponding to 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, 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 do not migrate, and for which the tacky nature has been virtually dispensed with, are therefore sought.

These objectives are achieved by the present invention, the subject of which is thus a cosmetic composition for making up and/or caring for the lips, which is in the form of a liquid emulsion comprising:

a) at least 5% by weight, relative to the total weight of the composition, of one or more nonvolatile oils;

b) 1 to 30% by weight of active substance, relative to the total weight of the composition, of at least one film-forming agent chosen from vinyl polymers comprising at least one carbosiloxane dendrimer-based unit;

c) at least 10% by weight of water relative to the total weight of the composition, d) at least one coloring material. The present invention also relates to a process for making up and/or caring for the lips, in which the abovementioned composition is applied to the lips. It further relates to a device comprising a container in which is stored the composition according to the invention, and comprising an application member with a porous application surface.

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

- Figure 1 is a sectional view of an application device according to a first embodiment;

- Figure 2 is an exploded view of an application device according to a second embodiment;

- Figure 3 is a sectional view of the device of Figure 2.

The film deposited on the lips has the advantage of being very thin and, in certain cases, of being virtually imperceptible by the user.

In addition, and this represents a very desired advantage, this deposit is not tacky. It also does not provide a feeling of dryness on the lips.

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

The expressions "at least one" and "several" are used without distinction. The term "oil" is intended to mean a non aqueous compound, non miscible in water, liquid, at 25°C and atmospheric pressure (760mmHg; 1.013.10⁵ Pa).

The term "liquid" is intended to mean a fluid texture, the viscosity of which at 25°C is more particularly between 0.005 and 15 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 composition (after which time stabilization of the viscosity and of the spin speed of the spindle are observed), at a shear rate of 200 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.

Whatever the direction of the emulsion, the composition according to the invention comprises at least 10% by weight of water and preferably from 20% to 60%> by weight relative to the total weight of the composition.

NON-VOLATILE OILS As indicated above, the composition according to the invention comprises at least 5% by weight, relative to the total weight of the composition, of one or more non- volatile oils.

Preferably, the content of non-volatile oil(s) is at least 8% by weight and preferably is between 10%> and 30% by weight relative to the weight of the composition. The non- volatile oil(s) is (are) more particularly chosen from non- volatile silicone oils, which may or may not be phenylated, non-volatile fluoro oils, polar or non-polar non-volatile hydrocarbon-based oils, or mixtures thereof.

The term "non-volatile" is intended to mean an oil of which the vapour pressure at 25°C and atmospheric pressure is non-zero and is less than 0.02 mmHg (2.66 Pa) and better still less than lO^"3 mmHg (0.13 Pa).

Silicone oils

The term "silicone oil" is intended to mean an oil containing at least one silicon atom, and in particular containing Si-0 groups.

Non-volatile non-phenylated silicone oils

The expression "non-phenylated silicone oil" denotes a silicone oil which does not have a phenyl substituent.

Representative examples of these non- volatile non-phenylated silicone oils which may be mentioned include polydimethylsiloxanes; alkyl dimethicones; vinylmethyl methicones; and also silicones modified with aliphatic groups and/or with functional groups such as hydroxyl, thiol and/or amine groups.

It should be noted that "dimethicone" (INCI name) corresponds to a polydimethylsiloxane (chemical name).

The non-volatile non-phenylated silicone oil is preferably chosen from non-volatile dimethicone oils.

In particular, these oils can be chosen from the following non- volatile oils:

- polydimethylsiloxanes (PDMSs), - PDMSs comprising aliphatic groups, in particular alkyl or alkoxy groups, which are pendent and/or at the end of the silicone chain, these groups each comprising from 2 to 24 carbon atoms. By way of example, mention may be made of the cetyl dimethicone sold under the commercial reference Abil Wax 9801 from Evonik Goldschmidt,

- PDMSs comprising aliphatic groups, or functional groups such as hydroxyl, thiol and/or amine groups,

- polyalkylmethylsiloxanes substituted with functional groups such as hydroxyl, thiol and/or amine groups,

A ratio between the components (A) and (B) of 0/100 means that the compound becomes a homopolymer of component (B).

A vinyl polymer containing at least one carbosiloxane dendrimer-based unit may be obtained by copolymerization of the components (A) and (B), or by polymerization of the component (B) alone.

The polymerization may be a free-radical polymerization or an ionic polymerization, but free-radical polymerization is preferred.

It may be a liquid, a gum, a paste, a solid, a powder, or any other form. The preferred forms are solutions consisting of the dilution of a dispersion or of a powder in solvents.

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

The silicone oil may 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- trifluoropropylsiloxane and of dimethylsiloxane having the two molecular ends capped with trimethylsiloxy groups, or similar unreactive linear silicone oils, and also hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane or a similar 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 may 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, camellia oil, squalane, castor oil, cottonseed oil, coconut oil, egg yolk oil, polypropylene glycol monooleate, neopentyl glycol 2 ethylhexanoate or a similar glycol ester oil; triglyceryl isostearate, the triglyceride of a fatty acid of coconut oil, or a similar oil of a polyhydric alcohol ester; polyoxyethylene lauryl ether, polyoxypropylene cetyl ether or a similar polyoxyalkylene ether.

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

A solution or a dispersion of the alcohol should have a viscosity within the range from 10 to 10⁹ mPa at 25°C. To improve the sensory use properties in a cosmetic product, the viscosity should be within the range from 100 to 5 10⁸ mPa.s.

The solutions and dispersions may be readily prepared by mixing a vinyl polymer containing at least one carbosiloxane dendrimer-based unit with a silicone oil, an organic oil, an alcohol or water. The liquids may be present in the polymerization step. 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 may be improved by adding a surfactant.

Such an agent may 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 a similar cationic surfactant; a polyoxyalkylene alkyl ether, a polyoxyalkylenealkylphenol, 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 may 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 within a range of 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.

These polymers may also be graft polymers or star polymers. Preferably, the associative polyurethanes are triblock copolymers in which the hydrophilic block is a polyoxyethylene chain comprising from 50 to 1000 oxyethylene groups.

FILLERS

The composition according to the invention may optionally comprise at least one or more filler(s) of organic or mineral nature.

The term "filler" should be understood to mean colourless or white solid particles of any shape which are in a form that is insoluble and dispersed in the medium of the composition. These particles, of mineral or organic nature, can give body or rigidity to the composition and/or softness and uniformity to the makeup. They are different from colorants.

Among the fillers that may be used in the compositions according to the invention, mention may be made of silica, kaolin, bentone, starch, lauroyllysine, and fumed silica particles, optionally hydrophilically or hydrophobically treated, and mixtures thereof.

A composition used according to the invention may comprise one or more fillers in a content ranging from 0.1% to 15% by weight and in particular from 1%> to 10%> by weight relative to the total weight of the composition.

ADDITIVES

The composition according to the invention may furthermore comprise any of the ingredients conventionally used as additives in the cosmetics and dermatology field.

These additives are advantageously chosen from antioxidants, thickeners, sweeteners, basifying or acidifying agents and preserving agents, and mixtures thereof, and may be chosen advantageously from those proposed in Table 1 of the Codex Alimentarius. As antioxidant, a composition in accordance with the invention may advantageously comprise at least one pentaerythrityl di-t-butyl hydroxycinnamate.

A composition according to the invention may also contain flavourings and/or fragrances.

As cosmetic active agents that may be used in the invention, mention may be made of sunscreens, vitamins A, E, C and B3, provitamins such as D-panthenol, calmatives such as OC- bisabolol, Aloe vera, allantoin, plant extracts or essential oils, protective or restructuring agents, refreshing agents such as menthol and derivatives thereof, emollients, moisturizers, antiwrinkle active agents and essential fatty acids, and mixtures thereof.

The amounts of each of these various ingredients are those conventionally used in the fields under consideration, and range, for example, from 0.01% to 10%> by weight relative to the total weight of the composition.

WATER-SOLUBLE SOLVENTS

The composition may, where appropriate, comprise, besides water, at least one water- soluble solvent.

In the present invention, the term "water-soluble solvent" denotes a compound that is liquid at ambient temperature and water-miscible (miscibility with water of greater than 50%> by weight at 25°C and atmospheric pressure).

The water-soluble solvents that can be used may also be volatile.

Among the water-soluble solvents that may be used in the compositions in accordance with the invention, mention may be made in particular of monoalcohols containing from 1 to 5 carbon atoms, such as ethanol and isopropanol, glycols containing from 2 to 8 carbon atoms, such as ethylene glycol, propylene glycol, 1,3-butylene glycol and dipropylene glycol, C3 and C4 ketones and C₂-C4 aldehydes.

When it (they) is (are) present, the content of water-soluble solvent(s) is at most 50% by weight relative to the weight of water, and preferably at most 30% by weight relative to the weight of water.

Needless to say, those skilled in the art will take care to select this or these optional additional compound(s), and/or the amount thereof, such that the advantageous properties of the composition according to the invention are not, or are not substantially, adversely affected by the envisaged addition.

The composition according to the invention may be manufactured via the known processes generally used in cosmetics or dermatology.

The composition according to the invention may be packaged in any type of device usual in the field of fluid cosmetic compositions intended particularly for lip application. Devices contemplated accordingly might include those having a container comprising a ball- equipped applicator (roll-on), a distributor pen container with at one end at least one aperture via which the composition can be discharged, or with a felt pad or flocked endpiece or brush at the end; or a container comprising an immersive applicator, for example a brush.

Such devices may or may not be given a mechanism for distributing the composition that allows said composition to be discharged from the container to the application member or to the substrate. This mechanism , it should be noted, may advantageously comprise a means of metering the composition. In one especially advantageous embodiment of the invention, the composition is packaged in a container and applied using an application member with a porous application surface.

The application member may be entirely porous, i.e. the composition may cross from an internal surface of the application member to an external surface of the application member, or vice versa.

The application member may in particular consist of one or more open-cell or semi-open- cell foams.

Thus, the application member may be made up of at least two portions of foam, of different compressibilities, which can be adhesively bonded together.

The foam may be non-crosslinked or preferentially crosslinked.

Still preferentially, the foam(s) is (are) elastically compressible. The term "elastically compressible" is intended to mean that, starting from a position deformed by a pressure exerted on its surface, the foam returns to its initial shape when the pressure is released.

With such materials, the releasing of the composition on the surface to be treated takes place either by capillary action on contact with the lips, or by expulsion of the composition, from the pores of the applicator, in response to a slight deformation (by pressure) of said applicator on the surface to be treated.

The application member may have a cylindrical shape and may have a circular cross section. As a variant, the application member may have any other shape, for example conical, flattened- cone, nose-cone or prism shape, and can have an oval, rectangular or polygonal cross section. It may also comprise a bevelled portion and/or a concave portion forming a hollow on the application surface. The application member may be symmetrical or asymmetrical relative to a longitudinal plane of said application member.

The visible part of the application member may have a cross section which falls within a circle advantageously having a diameter of between 2 mm and 20 mm, and preferably between 5 mm and 15 mm. The visible part of the application member, in the non-compressed position, may be between 2 mm and 20 mm in height.

The application member may consist of several different materials, in particular of a stack of foams having different characteristics. By way of example, the application member may consist of one or more foams chosen from polyether, polyester, polyurethane, polyester-polyurethane, NBR (natural butadiene rubber), SBR (synthetic butadiene rubber) or PVC (polyvinyl chloride) foams, or mixtures thereof, and quite particularly polyester-polyurethane, in particular the product S90 from Crest Foam Industries.

The density of the foam(s) forming the application member, measured according to standard

ASTM D 3574-05, may advantageously be between 0.02 g.cm ³ and 0.05 g.cm ³, for example 0.03 g.cm^"3. This density makes it possible to release an appropriate amount of impregnated composition.

The average number of pores or cells of the foam(s) may advantageously be between 25 and 50 pores per centimetre, for example equal to 35 pores per centimetre. The average pore size may advantageously be between 0.2 mm and 0.5 mm. It should be noted that the evaluation of the average number of pores is conventionally carried out visually by counting. Preferably, the cells or pores communicate with one another omnidirectionally.

The hardness of the application surface of the applicator member, measured by means of an F-type durometer from Asker, may advantageously be between 10 Asker F and 70 Asker F.

At least one part of the surface of the application member may be covered with a flock, in particular based on polyamide, rayon, cotton, viscose or nylon fibres. The flock contributes to creating a store of product, immediately in the neighbourhood of the application surface. In addition, it makes it possible to impart more softness on application, in particular when the application member is made of wide-cell foam. Furthermore, the flock may contribute to the homogenization of the spreading of the composition to form a thin film.

The flock may consist of a mixture of fibres of various length and/or nature and/or diameter.

The length of the fibres may advantageously be between 0.2 mm and 1 mm, for example equal to 0.75 mm.

The fibre count grading unit may advantageously be between 0.3 dtex and 3.3 dtex, for example equal to 1.7 dtex.

As a variant, the application surface can be covered with a permeable coating of textile, perforated plastic or felt type.

In accordance with one advantageous variant of the invention, the device comprises a composition-dispensing mechanism which makes it possible to expel said composition from the container to the application member.

According to this variant, said dispensing mechanism advantageously comprises a composition-metering means. Application devices that are particularly suited to this composition will be described with reference to the appended drawings, in which:

- Figure 3 is a sectional view of the device of Figure 2. According to a first embodiment represented in Figure 1, the device 1 comprises a cylindrical polypropylene body 2 having a longitudinal axis X. The body 2 denotes a first housing 3 (container), delimited by a cylindrical skirt 19, a first end 18 of which is open, and a second end of which, opposite the first, is closed by a transverse wall 16 comprising passages which emerge to form a grille 42. The transverse wall 16 separates the first housing 3 from a second housing 6, located above the first housing 3.

The upper housing 6 has a bottom 7, in the shape of a hemisphere, into which the passages forming the grille 42 emerge. One end of the housing 6, opposite the bottom 7, forms a free edge 8 delimiting an opening 9. The external surface of the housing 6 comprises a screw thread 10 intended to cooperate with a corresponding screw thread 11 provided for on the internal surface of a skirt 12 of a stopper 13. As a variant, the stopper is reversibly snap-fastened onto the external surface of the housing 6.

The stopper 13 is rigidly connected to an applicator 14 correspondingly made to match the hemispherical profile defined by the bottom 7 of the housing 6. The application member 14 may be adhesively bonded, welded or crimped onto the cap 13.

The application member consists of an open-cell polyurethane foam. The density of the foam forming the application member, measured according to standard ASTM D 3574-05, is advantageously between 0.02 g.cm ³ and 0.05 g.cm ³, for example equal to 0.03 g.cm ³.

According to one preferred variant, at least one part of the surface 14 of the application member is covered with a flock 15, in particular based on rayon, cotton, viscose or nylon fibres. The length of the fibres is advantageously between 0.2 mm and 1 mm, for example 0.75 mm. The fibre count grading unit is advantageously between 0.3 dtex and 3.3 dtex, for example equal to 1.7 dtex.

The application member 14 is proportioned relative to the housing 6 such that, when the stopper 13 is in the closed position, at least one portion of the application surface of the application member 14 is in contact with the bottom 7.

The application member 14 is proportioned such that, in this position, it is not appreciably axially compressed.

The composition of the invention is here referred to as product P. This product P is contained inside the housing 3 forming a container, the open end 18 of the housing 3 being closed via a dispensing mechanism 30. The latter is mounted by clip-fastening onto the body 2 of the housing 3, after filling with the product P inside the housing 3 through its open end 18. The mechanism 30 comprises an actuating wheel 31 mounted to rotate freely with respect to the body 2, via a bulge/groove arrangement. The wheel 31 is rigidly connected to a threaded rod 32 capable of axially driving a threaded piston 33, incapable of rotating inside the container, for example by virtue of a rib/notch assembly which prevents the piston from rotating inside the container. The mechanism may also comprise a metering means, such as a ratchet system, capable of periodically generating an audible sound, so as to inform the user of the amount of product dispensed. As a variant, the mechanism associated with the first housing, for causing the product to exit, may be different; for example, the walls of the body 2 may be deformable in order to apply, by crimping, an overpressure in the container so as to expel the product through the grille.

To use this device, the user turns the actuating wheel through half or one turn, with the cap 13 in the closed position over the opening 9 of the housing 6, so as to cause a corresponding amount of product P to pass from the container to the applicator 14 contained in the housing 6, via the passage of the grille 42. The product is taken up by the applicator 14, in particular by capillary action. All that then remains is for the cap 13 to be unscrewed so that the application member can be extracted therefrom and for the product P to be applied by moving the application surface of the application member 14 over lips, in order to deposit the product impregnated in the application member.

According to a variant which is not illustrated, the application member 14 is axially oversized with respect to the housing 6. Thus, after having applied all the product contained on the application member 14, it is possible to reload the latter, without having to rescrew the cap fully onto the device 1, simply by introducing the application member 14 into the housing 6 through the opening 9, and picking up either residual product resulting from the previous actuating of the wheel 31, or product resulting from a further actuating of the wheel 31, in the absence of the application member 14. According to a second embodiment represented in Figures 2 and 3, the device is in the form of an applicator bottle for a product P, and comprises mainly a container or reservoir 110 consisting of a body 111, one end of which is closed by a bottom 112. The other end of the reservoir 110 is surmounted by an application head which comprises an intermediate element 130 intended for mounting the head on the reservoir and an application member 120 housed in the intermediate element.

The intermediate element 130 comprises, on its external surface, means 132 (of screw thread or snap-fitting bead type) for enabling the removable mounting of a stopper 140 capable of covering the application member 120.

As a variant, a dispensing mechanism can be combined with the reservoir, for example a piston mechanism as previously described, or flexible walls making it possible to generate an overpressure in the reservoir in order to expel the product. Likewise, a ball 160 can be placed inside the reservoir so as to homogenize the product in order to facilitate the flow thereof and/or to facilitate the conveying thereof to the application member.

The internal wall of the intermediate element 130 defines a cylindrical internal housing 133 which rotates about an axis X. This housing 133 comprises a side wall 134 and a planar transverse wall 135 constituting the bottom of the housing. A fitting skirt 136 extends the side wall beyond the transverse wall, on the opposite side from the opening 131 of the intermediate element. The fitting skirt 136 is attached, by snap-fitting, onto the body of the reservoir, at the top of which a radial projection 114 is provided for, on the opposite side from the bottom 112. This snap-fitting system can of course be replaced with any other system of attachment, in particular a screw attachment system. A sealing skirt 137 is advantageously provided for on the transverse wall 135 of the housing so as to come into leaktight contact with the inside of the reservoir.

The body 111 of the reservoir, the intermediate element 130 and also the stopper 140 are made of rigid material, for example of polyethylene. It is obvious that these three independent elements can each be made of a different material. It is thus possible to envisage using a flexible material for at least one part of the reservoir.

The housing 133 communicates with the inside of the reservoir via a passage 139 which passes through a shaft 115 extending along the axis of the housing. The shaft is made up of a single part with the transverse wall 135 from which it extends to a free end, located inside the housing 133. The shaft has a circular internal cross section, which is constant throughout its axial height, whereas its external cross section decreases to the free end.

The diameter of the shaft is chosen according to the product contained in the reservoir, in such a way that the product coming from the reservoir can flow in the shaft, for example by simply shaking the assembly.

The application member 120 is mounted inside the housing 133 around the shaft 115.

The application member is in the form of a block of porous material(s), at least one part of which is elastically compressible.

According to one preferred embodiment, the application member is made up of a block of open-cell foam, in particular a block of polyurethane foam. Alternatively, the application member 120 may be made up of an axial succession of at least two portions of foam, of different compressibilities, which can be adhesively bonded together.

According to the example represented, the application member has a cylindrical shape and has a circular cross section. It is obvious that the application member can have any other shape, and can have any other cross section.

The application member 120 has a side wall 121, one end 122 of which constitutes a dome- shaped application surface.

Where appropriate, the application surface 122 can be covered with a flock. In this case, the flock can consist of hairs of various diameters and/or of various natures and/or of various heights, or of a mixture of such hairs.

On the opposite side from this application surface 122, the application member ends with a second open end 124 which comes into contact with the transverse wall 135 of the housing. The end 124 can be permanently attached to the intermediate element 130. Advantageously, this end is removably attached so as to make it possible to easily remove the application member in order, for example, to clean it. To this effect, the end 124 of the application member is covered with a permanent adhesive, for example an acrylic adhesive, which adheres more to the application member than to the wall 135. A portion 123 of the side wall located on the side of the open end 124 acts as a support for the application member. The portion 123 acting as a support for the application member is separated from the rest of the application member by an annular groove 150 which defines a zone of smaller cross section. The annular groove 150 provided for on the periphery of the application member enables the zone of smaller cross section to have a greater compressibility than the rest of the application member. Thus, when a pressure is exerted on the application surface, the maximum compression of the zone of smaller cross section is obtained before obtaining the maximum compression of the application member.

When the application member is mounted in the housing 133, it occupies approximately the entire housing, the application member having a shape approximately complementary to the shape of the housing. The application member 120 has in particular an axial recess 125, the shape of which is adjusted so that the application member comes to press against the wall of the shaft, without being substantially laterally compressed by said shaft. Alternatively, the side wall of the application member can be at a distance from the shaft. When the application member is in the relaxed position, the axial recess 125 has an axial height which is substantially greater than the axial height of the shaft 115 so as to define an internal cavity inside the application member, between an internal surface 126 located facing the shaft and the free end of the shaft. The portion 127 of the application member located above the cavity has an axial thickness which is smaller than the thickness of the lateral edge 121 of the application member, measured perpendicular to the axis X. The cavity can thus constitute a store of product in proximity to the application surface, it being possible for the product to come into contact with the application member only in the cavity.

Typically, the application member has a diameter of between 2 mm and 20 mm, and preferably between 5 mm and 15 mm. Its height, in the non-compressed position, can range between 2 mm and 20 mm.

Generally, the application member 120 comprises pores or open cells which have an average size of between 0.3 mm and 0.5 mm. Preferably, the pores or cells communicate with one another omnidirectionally.

In order to use the application assembly according to the invention, the user shakes the packaging and application assembly in order to bring the product into the shaft and into the application member. As a variant, the user actuates a dispensing mechanism in order to bring the product to the application member. Product is then kept inside the block of foam 120 of the application member by capillary action. All that is then needed is to bring the application member 120 into contact with the area to be treated; a slight pressure can be applied so as to place the product present in the cells of the foam in proximity to the application surface 122. Product is then spread by passing the application surface 122 over the support to be treated, by simple capillary contact, so as to draw the product in the form of a film, under the action of the affinity of the product that is exerted between the application surface and the support to be treated, without the slightest pressure being appreciably exerted on the application assembly. In the detailed description above, reference was made to preferred embodiments of the invention. It is obvious that variants can be introduced therein without departing from the spirit of the invention as claimed hereinafter.

In particular, the shape of the applicator may be different from the shape illustrated with reference to the embodiments that have just been described. Generally, the shape of the applicator is chosen according to the area to be treated. For example, in the case of an applicator for the lips, an applicator approximately in the shape of a cone, a nose-cone or a hemisphere will more particularly be used, the applicator optionally comprising a bevelled face.

Likewise, the applicator can be dissociated from a container containing the product without a dispensing mechanism. The device is then used by dipping the applicator in the container and then by applying the product to the lips by means of the applicator.

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

EXAMPLE 1

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.

B Brilliant yellow FCF aluminium lake on alumina 2.05

B Black iron oxide 1.36

B Cyclohexadimethylsiloxane 10

C Water 34.5

C 1,3-Butylene glycol 6

C Magnesium sulfate.7 H₂0 0.7

C Non-denatured 96-degree ethyl alcohol 5

2. Preparation

Firstly, the ingredients of phase B were mixed together and the whole mixture was milled in an Exakt three-roll machine.

Secondly, phase A was mixed with stirring using a Moritz mixer for 10 minutes.

At the end of this operation, phase B prepared beforehand was added and the stirring was maintained for a further 20 minutes.

Moreover, aqueous phase C was prepared with magnetic stirring, and was subsequently added, to phase A, with stirring using a Moritz mixer, maintained until a smooth and homogeneous mixture was obtained.

These various steps were carried out at ambient temperature.

The viscosity of the composition, measured in accordance with the protocol explained in detail in the description, is 0.15 Pa.s.

The composition was then introduced into a device similar to Figures 2 and 3, the application member of which consists of the S90NR foam from the company Crest Foam Industries, covered with a flock from the company ERZI Flock Technik (0.75 mm; 1.7 dtex).

The device makes it possible to apply a film to the lips, measured wet (therefore before drying), of 11.63±1.02 μιη.

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

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

The density of the composition is 1.

The average thickness is given with three separate measurements.

EXAMPLE 2

The preparation was the same as the one dscribed in example 1.

The composition was then introduced into a device similar to Figure 1, the application member of which consists of the S90NR foam from the company Crest Foam Industries, covered with a flock from the company ERZI Flock Technik (0.75 mm; 1.7 dtex).

The applied film, measured wet (therefore before drying), was of 3,06±0,96 μιη. The composition was very easily applied. The film was matt/satin, comfortable, with a good film wear, and no migration.

As a comparison, the composition was also applied by using an applicator for gloss lip compositions (FLEXIBLE APPLICATORS FLOCKED: Complete lip gloss package using applicator 14030 ; GEKA GMBH).

The applied film, measured wet (therefore before drying), was of 16,11±2.55 μιη and was more perceptible on the lip than the film applied according to the invention.
