Description

 "Applicator to apply a product on the eyebrows"

The present invention relates to an applicator for applying a product to the eyebrows, a packaging and application device comprising such an applicator and a method of cosmetic treatment of the eyebrows.

 There is a need to make eyebrow hairs, in particular in order to change their color, for example in order to obtain a result in harmony with the color of the hair.

 Various applicators for applying a product to the eyebrows have already been proposed.

 US Pat. No. 8,051,860 thus discloses a device for applying a coloring cosmetic composition to the region of the eyebrows, comprising a tip impregnated with said composition. Such a device is used in the manner of a buffer.

 EP 1 649 777 A2 discloses a device for packaging and applying a product on the eyelashes or the eyebrows, in particular mascara, comprising a comb having a relatively small number of teeth. Such a device is particularly suitable for making eyelashes in the corner of the eye.

 WO 2010/007588 A2 discloses an applicator having teeth extending in different directions, connecting to a body of generally cylindrical shape along the longitudinal axis of the applicator member. Although the application of product on the eyelashes is envisaged, such an applicator is more particularly suitable for the application of the product on the eyelashes of the eye.

 There is a need to further improve the applicators to apply a product on the eyebrows, especially to comb them and makeup precisely, without staining the skin.

 The invention aims to meet this need and it achieves this through an applicator comprising:

 - a rod,

 an application member attached to one end of the stem, comprising:

"A body having a free end and having an application face having a portion whose width decreases towards the free end, • pins protruding on the application face, at least some connecting to the portion of decreasing width, with on the application face a succession of at least three pins in the direction of the width and a succession of at least three pins in the direction of its length.

 The term "length" refers to the longitudinal direction of the applicator member and the term "width" refers to the perpendicular direction.

 Thanks to the invention, the user has an applicator that is particularly suitable for precise makeup of the fringe of the eyebrows. The user can use the applicator to color the eyebrows, without staining the skin. Preferably, this applicator is used with a container equipped with a wiper member, as detailed below.

 The rod of the applicator can be made relatively thin and does not hinder the vision of the eyebrow fringe when the user wears makeup.

 A narrower shape at the end of the applicator member is compatible with implantation of the pins suitable for precise and effective makeup of the fringe of the eyebrows, and the distal end of the applicator member can then be used to disciplining the eyebrows, as well as the back of the applicator, opposite to the application face, which can be achieved without application element.

 The applicator may comprise a succession of a maximum of four or five pins in the direction of the length of the application face and / or three to five pins in the width direction of the application face. The total number of pins carried by the applicator member is thus relatively small and preferably between 8 and 15. A relatively small number of pins is advantageous in that it facilitates the management of the eyebrows and the engagement of the hairs between the pimples. The applicator member is preferably used with a more fluid cosmetic composition than a mascara conventionally used for makeup of the eyelid hairs.

 All the pins are preferably located on the portion of the application face whose width decreases.

Preferably, the back of the applicator member, opposite to the application face carrying the pins, is smooth. This back can be used to discipline the hair during makeup, as indicated above. The pins may be arranged in rows with preferably a constant gap within the same row and, more preferably, a constant gap between the pins for all rows.

 Preferably, the number of pins per row decreases as one moves away from a longitudinal median plane of the applicator member.

 Preferably, the applicator member comprises a central row which has the largest number of pins, and the other rows have fewer pins than this central row. The latter is preferably located along a median plane of symmetry for the applicator member.

 The pins may be arranged in substantially concentric arches around a point situated in front of the applicator member.

 The pins may be arranged in rows aligned in the direction of the length of the application face.

 The pins may be arranged in rows parallel to the longitudinal axis of the applicator member. These rows may or may not be offset relative to each other in the longitudinal direction of the applicator member, the offset between two adjacent rows being for example between ¼ and ¾ of the average spacing between the pins within the same row, gauge measured at the base of the pins.

 The pins are preferably of longitudinal axis parallel to the same direction, which is preferably non-parallel and not perpendicular to a longitudinal axis of the applicator member.

 The longitudinal axis of the pins is preferably at an angle to the longitudinal axis of the applicator member which is not straight, so that the pins are oriented obliquely with respect to the longitudinal axis of the rod, preferably at an angle α between 30 and 80 °. The pins are thus preferably oriented towards the front of the applicator.

 Preferably, no pin is of longitudinal axis parallel to the longitudinal axis of the rod. Also preferably, no pin is of longitudinal axis perpendicular to the longitudinal axis of the rod.

The longitudinal axis of the applicator member may or may not coincide with the longitudinal axis of the rod. The application face may be slightly convex towards the outside, and the envelope surface defined by the free ends of the pins may also be convex outwards, being for example parallel to the application face. As a variant, and preferentially, the free ends of the pins all belong to the same plane, which preferably is not parallel to the longitudinal axis of the applicator member.

 The body of the applicator member preferably has a generally flattened shape in a plane of flattening, which can be oriented generally perpendicular to a median plane for the application face. The greatest width of the body of the applicator member is preferably greater than the length of the larger of the pins.

The greatest width w _mx the body of the applicator member may be greater than the diameter d _t i _age of the applicator rod in its region adjacent to the applicator member.

 When the applicator member is observed along its longitudinal axis, the pins of the pins may be oriented substantially perpendicular to said flattening plane.

 A flattened shape of the body of the applicator member is advantageous in that it tends to ovalize the wiper member as the applicator member passes and may lead to further spinsing of the spikes, which reduces the amount of product present at their ends and decreases the risk of staining the skin by excessive product intake.

 The applicator member may have a symmetrical shape with respect to a longitudinal median plane. At least one row of pins may extend along this longitudinal median plane.

 Preferably, the pins are molded with the body of the applicator member in one piece and preferably in an elastomeric material, so as to provide flexibility to the applicator member.

 In particular, the applicator member may have sufficient flexibility for the pins and / or the body of the applicator member to be deformable during passage through the wiper member and / or during the application of the product on the eyebrows.

The applicator member preferably comprises a tip which is molded in one piece with the body of the applicator member. This tip serves to mount the applicator member in the rod, the latter having a housing for this purpose.

 The longitudinal axis of the nozzle can make a non-zero angle with the longitudinal axis of the body of the applicator member. Preferably, the longitudinal axis of the body of the applicator member coincides with the longitudinal axis of the endpiece.

 It is particularly advantageous that the spikes are not flocked because it reduces the amount of product retained end and therefore the risk of applying the product on the skin.

 The pins may have the same length. However, preferably, the pins have a variable length.

 It is thus particularly advantageous that the applicator member comprises a pin of greater length located near its distal end. This pin is preferably of longitudinal axis located in a median plane of symmetry of the applicator member.

 Within a row of pins, in particular a central row of pins, preferably located along a median plane of symmetry for the applicator member, the length of the pins can thus grow closer to the end. free of the applicator member, preferably at least 20%, passing for example from 2.4 mm to 3 mm, in this case 25% increase.

 A longer pin, close to the distal end of the applicator member, is advantageous in that it allows the user to have both a well-wrung pin and a stock of product. in the vicinity, constituted by the drop of product which tends to remain in the extension of the applicator member after spinning, because not removed by the wiper member. Such a pin can help the user in the realization of a precise and neat makeup.

 The application face on which the pins are connected is preferably inclined relative to the longitudinal axis of the applicator member.

The pins may be connected in a non-straight manner on this application face, preferably being slightly inclined forwards when the applicator member is observed in section in a plane parallel to its longitudinal axis, for example in section in a median plane when the applicator member comprises a central row extending along this median plane. The longer pin may be connected by its base to the application face set back from the free end of the applicator member, a distance that is for example substantially equal to the distance separating it from the pin next in the row.

 In a most preferred embodiment, the applicator member comprises a central row of at least three pins, preferably four pins, the length of which increases, preferably linearly approaching the free end of the application member, and two lateral rows of at least two pins each, preferably axially offset from the central row by about half of the distance between two consecutive teeth, measured at their base, of the row Central. All the pins are in this preferred embodiment present on a portion of the application face whose width decreases towards the free end of the applicator member. The pins are connected to an inclined application face and are preferably of longitudinal axes parallel to each other, being preferably all inclined forwardly.

 The invention further relates, in another of its aspects, a packaging device and application comprising an applicator according to the invention and a container containing the product to be applied.

 This container is preferably provided with a wiper member of the rod and the applicator member, which is traversed by the applicator member when the applicator is removed from the container. It is particularly advantageous for the body of the applicator member to be wider than the smallest inner diameter of the wiper member, since this makes it possible to wring more vigorously the spikes, whose tip thus bears less product. , which reduces the risk of staining the skin and can facilitate the obtaining of a neat makeup. The applicator may comprise a gripping member arranged to close the container in the absence of use. The rod of the applicator is connected to this gripping member.

The invention further relates to an eyebrow makeup process, in which a cosmetic product is applied, using the applicator according to the invention, to the eyebrows. The product is advantageously taken from a container provided with a wringing member. The product is applied using the pins and the application face. The back of the applicator can be used to move the hair without trying to deposit the product.

- Figures 27 to 51 show in elevation, including front, back and side, other examples of application members according to the invention.

 The device 1 for packaging and application shown in Figure 1 comprises an applicator 10 according to the invention and a container 20 containing a product P to be applied with the applicator 10 on the eyebrows.

 The applicator 10 comprises a rod 1 1 which is connected to a gripping member 12 arranged to be fixed on the container 20 in the absence of use, in order to close the latter in a sealed manner.

 The rod 11 carries at its distal end, opposite to the gripping member 12, an application member 30 according to the invention, comprising pins 34.

 The rod 11 may be rectilinear and circular in section.

 The applicator member 30 may extend along a longitudinal axis X which may be coincident with that of the rod 11, as illustrated.

 The attachment of the applicator 10 to the container 20 can be effected in various ways and for example by screwing the gripping member 12 on a neck 21 of the container 20. This neck 21 can accommodate at least partially a body of dewatering 25 of the rod 11 and the applicator member 30, this wiper member 25 being of any type known in itself, and in particular with a flexible lip as illustrated for example in FIG. 45 of the WO publication. 2010/007588 A2 or Figures 25 to 28 of the application FR 2 900 036.

 The smaller diameter of the wiper member 25 may be equal to the diameter of the rod 1 1, in its portion adjacent to the applicator member.

Although the use of a container equipped with a wiper member is preferred because it allows to leave little product at the end of the pins 34, the product P can still be contained in a container arranged to allow the loading the applicator member 30 into a product without passing through a wiper member. For example, the product may be contained in a container provided with a foam or a wall permeable to the product, in contact with which the applicator member 30 may be brought to load in product. In a variant, the product is brought into contact with the applicator member being taken directly by the latter in a jar containing the product or applied to the applicator member 30 by extraction of a tube.

The rod 11 may have any shape but, preferably, the rod 11 has a circular section whose diameter d _t i _ge is less than the largest transverse dimension Wmax of the applicator member 30. Thus, the latter distorts the wiper member 25 at its crossing.

 The rod 11 may be hollow or solid, being provided at its distal end with a housing into which may be inserted a tip 31 of the applicator member 30, visible in FIG. 2. This endpiece 31 may be fixed in the housing of the rod 11 by any known means and for example by stapling, crimping, gluing, screwing, latching or welding.

 In a variant not shown, the rod 11 is made in one piece with the application member 30 by molding material in one or more materials.

 The container 20 may have a body of thermoplastic material or glass, of any shape, opaque or transparent.

 Preferably, and in general, the product P is as described later, in the "Product" section.

 Preferably, the body 32 has a circular shoulder 37 at the connection with the tip 31 and the diameter of this shoulder 37 at the base of the body 32 corresponds to the outer diameter of the rod 11, so that the body 32 comes to position itself externally in the prolongation of the rod 11, without sensitive recoil.

 The body 32 of the applicator member defines an application face 33 which carries the pins 34.

 In the example, the applicator member 30 is made in one piece by molding the same thermoplastic material, preferably an elastomer. The pins 34 are not flocked. However, it is not beyond the scope of the present invention when the pins 34 are made of a material different from that of the body 32, for example a softer or harder material.

The application face 33 has a portion 38 whose width decreases from the maximum Wmax towards a free end 36 of the applicator member 30. The total length L of the applicator member 30, which is apparent after assembly of the applicator member 30 on the rod 11, is for example between 10 and 12 mm.

In the example considered, the width of the apparent portion of the applicator member 30, as observed in FIG. 2, decreases from the shoulder 37 and then increases to reach the maximum Wma _X , and decreases again along the portion 38.

 The maximum width of the body 32 of the applicator member 30 is for example between 4 and 8 mm, being for example equal to 6 mm.

 The thickness of the portion 38 may also decrease, as can be seen in FIG. 3, toward the free end 36.

The maximum thickness ema _X of the body 32 is for example between 3 and 3.6 mm, being for example 3.3 mm. The maximum thickness ema _X can be reached where the width is also maximum, and this maximum thickness can be reached in a median plane of symmetry M for the applicator member 30.

 It is advantageous for the body 32 of the applicator member 30 to be wider than the internal diameter of the wiper member 25, since this makes it possible to expand the wiper lip as the applicator member passes. 30 and therefore more vigorously spun the pins 34, to leave less product in the vicinity of their free end.

 It is particularly preferred that the applicator member 30 has a flattened cross section along a flattening plane F, which is generally perpendicular to the longitudinal axis of the pins 34 after axial projection thereof on a plane perpendicular to the longitudinal axis of the body 32, as can be seen in FIG.

 In the example considered, the pins 34 are of Y axis parallel to each other, thus being all oriented in the same direction, which makes an angle with the plane F according to which the body 32 of the application member 30 is flattened.

 This angle α is for example about 60 °, being preferably between 30 and 80 °. Thus, as seen in Figure 3, the pins 34 are oriented towards the front of the applicator.

 The pins 34 may have various shapes and for example, as illustrated, a conical shape, with a hemispherical tip.

The length / pins 34 is for example between 2 and 4 mm, being for example equal to 3.5 mm in the example of Figures 2 to 15. It can be seen in FIG. 5 that on the portion 38 of the application face whose width decreases towards the free end 36, a row 34a of at least three pins 34 succeeding one another in the longitudinal direction is connected. The application face 33 also carries a succession 34b of at least three pins in the direction of its width, that is to say in a direction perpendicular to the longitudinal median plane M in the illustrated example.

 As can be seen in FIGS. 2 and 5 in particular, the applicator member 30 may comprise a central row 34a of pins 34 which is arranged along the median plane M, this row of pins comprising the largest number of pins, in this case four in the illustrated example.

 The pins 34 may be arranged in various ways on the application face 33 and, for example, as illustrated in FIG. 5, in a substantially concentric manner along concave implantation edges C that are concave towards the free end 36.

 In the example of FIG. 5, the applicator member 30 thus comprises three successions of spikes 34 each arranged in a circular arc C, the first succession comprising five spikes 34 and the two following three spikes 34.

 The free end 36 may have various shapes and for example be curved towards the application side, as can be seen in particular in FIG. 3, in order to define a hemispherical point whose diameter d at the base is for example between 0.4 and 0.5 mm. The distance t between the apex of the tip and the nearest pin 34, measured along the longitudinal axis of the applicator member 30, is for example between 1 and 2 mm, being for example equal to 1, 5 mm.

 Within each row of pins 34 extending longitudinally, the spacing r between two consecutive pins 34 may be between 0.80 and 1 mm, being for example equal to about 0.9 mm. This spacing r can be the same within a row and the same for all the longitudinal rows, as illustrated in FIG.

 The distance between two consecutive pins 34 along an arc C can be of the same order.

The size in the direction of the height, when the application member 30 is observed in projection along the longitudinal axis of the body 32 as in Figure 4, measured between the back 39 of the application member and the highest free end of the pins 34, is for example between 6 and 7 mm, being for example equal to 6.5 mm. The application face 33 is preferably convex, as illustrated in FIG. 4, so that the free ends of the pins 34 of the central row 34a exceed those of the other rows, when the applicator member 30 is observed according to FIG. longitudinal axis of the body 32.

 To use the applicator 10 of Figures 1 to 5, the user extracts it from the container 20 and applies the product P with the pins 34 on the eyebrows. When it is withdrawn from the container 20, the applicator member 30 passes through the wiper member 25, and the excess product is removed from the free ends of the pins 34. After use, the user places the applicator 10 on the container 20 and the gripping member 12 ensures the sealing of the latter.

 The variant embodiment of the applicator member 30 illustrated in FIGS. 6 to 9 differs from that described with reference to FIGS. 2 to 5 essentially by the implantation of the pins 34 on the application face 33. In the example of FIGS. Figures 2 to 5, the axial offset between the longitudinal rows of pins 34 is relatively small, being related to the implantation of the pins according to circular arcs C.

 In the example of Figures 6 to 9, the axial offset between adjacent rows is more pronounced, and is performed so as to have a substantially staggered arrangement of the pins in the lateral direction, as can be seen in particular in Figure 9. In the example of FIGS. 6 to 9, the applicator member 30 comprises five rows of spikes, parallel to the median plane M, namely a central row of five spikes, two intermediate lateral rows of three spikes 34 each, and two external lateral rows of two pins each.

 Most, but not all, of the pins 34, is connected to the portion 38 whose width decreases towards the free end 36.

In the example of FIGS. 10 to 13, the body 32 of the applicator member 30 is narrower, for example with a width w _max of between 4 and 6 mm, for example equal to 5 mm, for a space requirement of height s for example equal to that of the examples of Figures 4 and 8.

The maximum thickness ema _X may also be equal to that of the examples of FIGS. 3 and 7.

In the example of FIGS. 10 to 13, it can be seen that the pins 34 can be arranged with a number of pins 34 in the lateral direction at most equal to three, with for example as illustrated a central row 34a of four pins 34, and two lateral rows of two pins each.

 In the example of Figures 14 to 17, the body 32 has the same shape as in the example of Figures 10 to 13, but the implantation of the pins 34 is modified, with an axial offset between the adjacent longitudinal rows of pins 34 , so as to obtain as illustrated in Figure 17 a substantially staggered arrangement of the pins 34 in the lateral direction.

 In the example of these figures 14 to 17, the applicator member comprises a central row 34a of four pins 34 and two lateral rows of two pins 34 each only.

 In the example of Figures 18 to 21, the pins 34 are closer together in the longitudinal direction, for example with a spacing r at their base between 0.5 and 0.6 mm.

 The applicator member 30 comprises for example a central row 34a of five pins 34 and two lateral rows of three pins, with an axial offset between the rows, so as to obtain a staggered arrangement.

 The variant embodiment of FIGS. 22 to 26 is particularly preferred.

In this variant, the pin 34 which is closest to the free end 36 is longer than those of the same row.

 It is seen in particular in Figure 26 that the length of the pins 34 increases in approaching the free end 36. This growth can be linear, as illustrated.

The length of the pins pass for example from _m i _n l _max, with _m i _n = 2.4 mm and

 The diameter m of a pin 34 at its base is for example between 0.5 and 0.6 mm.

 In the illustrated example, the applicator member 30 comprises a central row 34a of four pins 34 and two lateral rows 34c of two pins 34 each, with a longitudinal offset between the pins 34 of a row 34c and those of the row 34a substantially of the value of Γ spacing r between two pins 34.

The pins 34 of the lateral rows 34c may also have a height / which increases as it approaches the free end 36. When the applicator member is viewed from the side, as illustrated in FIG. 23, the ends of the spikes 34 may all be located in the same plane N, which may be non-parallel to the longitudinal axis of the spine member. application 30 and not parallel to the longitudinal axis of the rod 11 of the applicator.

 Numerous modifications can be made to the invention, and in particular to the shape given to the body 32.

 In the examples of Figures 27 to 51, the applicator member 30 comprises a central row of four pins and two lateral rows limited to a single pin, but the implantation of the pins 34 could be other, and for example identical to the any of the implantations that have been described with reference to Figures 1 to 26.

 In the example of Figures 27 to 29, the back of the body 32 of the applicator member 30 has a central edge, which extends in a median plane of symmetry.

 In the example of Figures 30 to 32, the back of the body 32 has a twisted shape.

 In the example of Figures 33 and 34, the back of the body 32 is concave outwardly, when the applicator member 30 is viewed from the side.

 In the example of Figures 35 and 36 and that of Figures 37 and 38, the body 32 has, in side view, a generally triangular shape.

 In the example of Figures 39 and 40, the body 32 is perforated, between the portion 38 of decreasing width and the attachment piece 31 on the rod.

 In the example of FIGS. 41 and 42, the body 32 has ridges 60, between the portion 38 and the endpiece 31.

 In the example of FIGS. 43 to 45, the free end 36 is substantially flat, in front view.

 In the example of FIGS. 46 to 48, the application face 33 is delimited on a part of its length by two opposite sides which are parallel to each other, before joining at the end in a rounded manner, which delimits the portion of decreasing width 38.

 In the example of Figures 49 to 51, the back of the body 32 is completely rounded.

Quantum dots are luminescent semiconductor nanoparticles capable of emitting, under light excitation, radiation having a wavelength of between 400 nm and 700 nm. These nanoparticles are known from the literature. In particular, they can be synthesized according to the methods described for example in US Pat. No. 6,225,198 or US 5,990,479, in the publications cited therein, as well as in the following publications: Dabboussi BO et al (CdSe) ZnS core quantum dots: synthesis and characterization of a series of highly luminescent nanocrystallites. Journal of Phosphical Chemistry, Vol 101, 1997, pp 9463-9475. and Peng, Xiaogang et al., "Epitaxial Growth of Highly Luminescent CdSe / CdS core / shell nanocrystals with photostability and electronic accessibility" Journal of the American Chemical Society, vol 119, No. 30, pp 7019-7029.

 The variety of pigments that can be used in the present invention provides a rich palette of colors, as well as particular optical effects such as interferential metallic effects.

 The size of the pigment used in the cosmetic composition according to the present invention is generally between 10 nm and 200 μτη, preferably between 20 nm and 80 μτη, and more preferably between 30 nm and 50 μιη.

 The pigments can be dispersed in the product by means of a dispersing agent.

The dispersing agent serves to protect the dispersed particles against agglomeration or flocculation. This dispersing agent may be a surfactant, an oligomer, a polymer or a mixture of several of them, bearing one or more functionalities having a strong affinity for the surface of the particles to be dispersed. In particular, they can cling physically or chemically to the surface of the pigments. These dispersants have, in addition, at least one functional group compatible or soluble in the continuous medium. In particular, using the esters of 12-hydroxystearic acid, in particular fatty acid C ₈ -C ₂ o and polyol such as glycerol, di- glycerol, such as the stearate of poly (12 -hydroxy stearic) with a molecular weight of approximately 750 g / mol, such as that sold under the name Solsperse 21 000 by the company Avecia, the 2-polyglyceryl dipolyhydroxystearate (CTFA name) sold under the reference Dehymyls PGPH by the company Henkel or polyhydroxy stearic acid such as that sold under the reference Arlacel PI 00 by Uniqema and their mixtures. As another dispersant that can be used in the compositions of the invention, mention may be made of the quaternary ammonium derivatives of polyfluorinated fatty acids, such as Solsperse 17 000 sold by the company Avecia, poly dimethylsiloxane / oxypropylene mixtures such as those sold by the company. Dow Corning as DC2-5185, DC2-5225C.

 The pigments used in the cosmetic composition according to the invention may be surface-treated with an organic agent.

 Thus, the previously surface-treated pigments useful in the context of the invention are pigments which have undergone totally or partially a chemical, electronic, electro-chemical, mechanical-chemical or mechanical surface treatment with an organic agent such as those described in particular in Cosmetics and Toiletries, February 1990, Vol. 105, p. 53-64 before being dispersed in the composition according to the invention.

 The surface-treated pigments useful in the cosmetic composition according to the invention may also have been treated with a mixture of these compounds and / or have undergone several surface treatments.

 The surface-treated pigments useful in the context of the present invention may be prepared according to surface treatment techniques well known to those skilled in the art or found as such in the trade.

Preferably, the surface-treated pigments are covered by an organic layer. The organic agent with which the pigments are treated can be deposited on the pigments by solvent evaporation, chemical reaction between the molecules of the surfactant or creation of a covalent bond between the surfactant and the pigments.

 The surface treatment can thus be carried out for example by chemical reaction of a surfactant with the surface of the pigments and creation of a covalent bond between the surfactant and the pigments or fillers. This method is described in particular in US Pat. No. 4,578,266.

 Preferably, an organic agent bound to the pigments will be used covalently.

 The agent for the surface treatment may represent from 0.1% to 50% by weight of the total weight of the surface-treated pigment, preferably from 0.5% to 30% by weight, and still more preferably from 1% to 10% by weight. weight.

 Thickening agent

 According to a preferred embodiment, the composition according to the invention comprises at least one thickening agent chosen from inorganic or organic thickening agents, polymeric or non-polymeric, and mixtures thereof.

 By thickener is meant a compound that modifies the rheology of the medium in which it is incorporated.

 According to a particular embodiment of the invention, the composition comprises at least one mineral thickener.

 Preferably, the thickener (s) is (are) chosen from fumed silica, clays, or mixtures thereof.

The fumed silicas can be obtained by high temperature pyrolysis of a volatile silicon compound in an oxyhydrogen flame, producing a finely divided silica. This process makes it possible in particular to obtain hydrophilic silicas which have a large number of silanol groups on their surface. Such hydrophilic silicas are, for example, sold under the names "AEROSIL 130®", "AEROSIL 200®", "AEROSIL 255®", "AEROSIL 300®", "AEROSIL 380®" by the company Degussa, "CAB-O- SIL HS-5® "," CAB-O-SIL EH-5® "," CAB-O-SIL LM-130® "," CAB-O-SIL MS-55® "," CAB-O-SIL M -5® "by the company Cabot.

 It is possible to chemically modify the surface of said silica, by chemical reaction generating a decrease in the number of silanol groups. In particular, it is possible to substitute silanol groups with hydrophobic groups: a hydrophobic silica is then obtained.

 The hydrophobic groups can be:

trimethylsiloxyl groups, which are especially obtained by treatment of fumed silica in the presence of hexamethyldisilazane. Silicas thus treated are called "Silica Silylate" according to the CTFA (6 ^th edition, 1995). They are for example marketed under the references "AEROSIL R812®" by Degussa, "CAB-O-SIL TS-530®" by Cabot.

- Dimethylsilyloxyl or polydimethylsiloxane groups, which are obtained in particular by treatment of fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas thus treated are called "Silica dimethyl Silylate" according to the CTFA (6 ^th edition, 1995). They are for example sold under the references "AEROSIL R972®", "AEROSIL R974®" by the company Degussa, "CAB-O-SIL TS-610®", "CAB-O-SIL TS-720®" by the company Pooch.

 The organophilic clay may be selected from montmorillonite, bentonite, hectorite, attapulgite, sepiolite, and mixtures thereof. The clay is preferably a bentonite or a hectorite.

 These clays can be modified with a chemical compound chosen from quaternary amines, tertiary amines, amino acetates, imidazolines, amine soaps, fatty sulphates, alkyl aryl sulphonates, amino oxides, and mixtures thereof.

 As organophilic clays, mention may be made of quaternium-18 bentonites such as those sold under the names Bentone 3, Bentone 38, Bentone 38V by Rheox, Tixogel VP by United catalyst, Claytone 34, Claytone 40, Claytone XL by Southern Clay Company; stearalkonium bentonites such as those sold under the names Bentone 27 by Rheox, Tixogel LG by United Catalyst, Claytone AF, Claytone APA by Southern Clay; quaternium-18 / benzalkonium bentonite such as those sold under the names Claytone HT, Claytone PS by Southern Clay.

 The thickener may also be chosen from organic compounds.

 For example, the following products, polymeric or non-polymeric, may be mentioned:

- C10-C30 fatty amides such as lauric diethanolamide the glyceryl poly (metha) crylate polymers sold under the names "Hispagel" or "Lubragel" by the companies Hispano Quimica or Guardian,
