Description

Set of packaging and application of a liquid cosmetic product.

The present invention relates to a set of packaging and application of a liquid cosmetic product.

"Cosmetic product" means any product as defined in Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products. The packaging and application assembly is more particularly intended for the application of a cosmetic product on a human keratinous surface, such as skin, lips or nails.

The development of formulations dedicated to makeup and / or care of the skin and / or lips, with satisfactory properties in terms of application, comfort, hold and coverage, but also in terms of makeup effect such as gloss, for example, is a permanent goal.

Many sets of packaging and application have been developed to allow a satisfactory and comfortable application of such fluid products.

In general, a set of packaging and application of a cosmetic product comprises, on the one hand, a body forming a reservoir intended to contain the cosmetic product to be applied, and, on the other hand, an applicator comprising a body of application defining an application surface intended to come into contact with a body surface of the user. By way of example of an applicator, mention may be made of document FR2872999 which describes a packaging and application assembly comprising an applicator, in particular for lips, said to be plunging.

An applicator is said to plunge when the loading of cosmetic product is carried out by dipping or immersing its applicator member in said cosmetic product.

Plunging the applicator into the cosmetic product allows a large load of the applicator. It is then generally necessary to equip the tank with a squeezing device to eliminate excess product. However, it is common to seek to increase the load of the applicator, for example by providing a central orifice.

Other packaging and application packages are also known which aim to better control the product load on the applicator. By way of example, mention may in particular be made of documents FR 2 832 297, FR 2 814 651 and FR 2 962 890.

The document FR 2 832 297 describes a set of packaging and application of a cosmetic product comprising a reservoir on which is mounted a porous applicator member which is traversed by the cosmetic product. The assembly comprises a cap which, in the closed position, compresses the applicator member so as to provide, on opening, a pumping effect of the cosmetic product facilitating its diffusion through the applicator member.

FR 2 814 651 and FR 2962890 still show another way of loading a product on the applicator member. More specifically, the documents FR 2 814 651 and FR 2 962 990 provide a reservoir body, said body having a housing adapted to receive the applicator member and a partition wall with the reservoir has at least one through hole in direct fluid communication with said tank. By agitating or inverting the assembly, the cosmetic product passes through the openings and impregnates the applicator member directly onto its application surface.

The document FR 2 814 651 aims at an optimal and relatively important loading of the application member. To do this, the document FR 2 814 651 provides a porous application member with open porosity, the dispensing orifices of the cosmetic product being arranged facing an uncompressed application portion when said applicator member is in place. in the accommodation. The dispensing orifices are distributed substantially over the entire application surface.

The document FR 2 962 890 meanwhile aims not to overload the application member. To do this, the document FR 2 962 890 provides for the association of precisely localized orifices with an application surface constituted by a non-permeable membrane to the product.

Despite the many types of packaging and application packages developed, there is still a need for assemblies to improve the application properties of certain cosmetics.

The applicant has notably found that certain formulations of cosmetic products still required the development of specific applicators to optimize their application and make-up on the user. The packaging and application assembly targeted by the present application is particularly intended for the application of a cosmetic product such as lip oil.

Such a composition intended more particularly for makeup and / or care of the lips is in a liquid form and comprises for example at least 70% by weight of non-volatile oils, in particular silicone, and solid particles, colored or otherwise, by examples of pigments and / or nacres.

Formulas for makeup and / or care of the lips have been known for a very long time and come in various forms, ranging from fluid formulas such as gloss, to solid compositions in the form of stick, supported or not, or compositions in pencil form.

In order to further diversify the compositions proposed to consumers, anhydrous or almost anhydrous formulas have appeared, even more fluid than gloss, and comprising high levels of oils, very comfortable to wear. However, these formulas are only available in unstained versions. This is mainly because it is very difficult to maintain high levels of suspended particles in this type oily medium, without losing the appeal of such compositions, which is precisely their great fluidity.

Indeed, with significant amounts of pigments, nacres or fillers, there is a sedimentation of these particles leading to the formation of a relatively unattractive cake, which may include clusters of particles. The cake thus formed has the additional disadvantage of being very cohesive. Thus, it can not be redispersed easily so as to find a homogeneous composition. Therefore, once the particles sedimented, the composition becomes almost unusable and no longer allows to obtain a uniform deposit on the lips, which is not acceptable.

Thus, to minimize the sedimentation problem, these compositions comprise relatively low levels of solid particles. But in this case, the number of accessible shades and their intensity is limited. The compositions may also comprise dyes, thus soluble species in the medium where they are used. However, the number of dyes that can be used in this field is relatively small, which makes it difficult to extend the color ranges proposed or their intensity, whether or not the dyes are combined with colored solid particles.

In addition to the formulation difficulties mentioned above, this type of cosmetic product tending to sediment also raises application difficulties that the current packaging and application packages do not optimally solve.

More precisely, given the presence of solid particles, the packaging assembly must in particular allow a homogeneous resuspension of the solid particles and ensure a good loading of the applicator for easy and precise application with optimal makeup rendering.

Given these constraints, the internal-feed type assemblies in which the product must diffuse through the application member are not suitable, the diffusion is not carried out in a homogeneous manner.

The so-called plunging applicators are also not optimal because the resuspension of the particles homogeneously in the cosmetic product is difficult. Moreover, in view of the high coloring power of the pigmented compositions and the high levels of oil in the lip oil compositions, it is necessary to be able to control the charge of the applicator. In case of too much load, it is interesting that the user can blur the skin or lip surface concerned with a surface of the applicator uncharged or relatively light.

A device as described in document FR 2 814 651 has not proved satisfactory either, although it allows a relatively easy resuspension by simple manual shaking of the bottle.

Although document FR 2 962 890 refers to compositions that may contain pigments, it has been found that such a set does not give satisfactory results. One problem is that such an applicator unloads the formula very quickly.

The present invention aims to achieve all or part of these objectives and proposes for this purpose, a set of packaging and application of a liquid cosmetic product comprising, on the one hand, a body forming a reservoir for containing the cosmetic product to apply, and secondly, an applicator comprising an applicator member defining a convex application surface having at least one vertex.

The reservoir body comprises a housing adapted to receive the applicator member and a partition wall with the reservoir has at least one through hole in direct fluid communication with the reservoir. Said orifices are located only at at least one bottom of the housing facing the vicinity of an apex of the applicator member when said applicator member is in place in the housing of the reservoir body. The packaging and application assembly is characterized in that the applicator member is made from a porous open-cell material.

The presence of an applicator member defining a convex application surface having a crown or a point makes it possible in particular to apply the product precisely.

The orifices provided in the wall of the receiving housing of the applicator member make it possible in particular to load the applicator member with a cosmetic product, in particular when the reservoir is agitated or turned over.

By "orifice located only at at least one bottom of the housing" is meant that the remainder of the partition wall is full, that is to say not pierced.

Thus, by associating one or more dispensing orifices in direct fluid communication arranged in a very localized manner with a porous application surface, the Applicant has surprisingly found that the intended packaging and application assembly allowed a precise application, comfortable and homogeneous cosmetic product contained in the reservoir, and in particular for cosmetics containing solid particles such as nacres and / or pigments.

As is known, the implementation of very localized orifices makes it possible to limit the passage of the product through the partition wall and thus to obtain a precise dose of product without overloading the applicator.

In the context of use with a liquid cosmetic product containing solid particles, and in particular having a tendency to sediment or phase shift, the Applicant has found that contrary to what she thought, the presence of localized orifices facing the application tip of the application member was able to recover a much more homogeneous amount of formula than if they were distributed with respect to the entire application surface. Thus, even if they are located at the bottom of the sieve and at the tip of the applicator, one still obtains a loading of the porous applicator by homogeneous product.

Without wishing to be bound by any theory, the Applicant believes that the use of an application surface made from a porous open-cell material greatly facilitates the retention of solid particles such as pigments and pearlescent agents. the excess of solvent, and especially oil can diffuse more easily through the material. The difference in migration between the solvent phase and the solid particles thus seems to provide particularly interesting makeup properties.

This results in a concentration of the particles of the type pigments and nacres around the tip of application. This allows a precise application, which does not run, and with great coverage.

The rest of the application surface, in particular a peripheral or lateral zone, can serve to soften the applied product and refine the makeup.

The solvent phase, in particular the oil, having diffused through the porous applicator contributes to a great softness of application over the entire application surface.

By direct fluid communication is meant that the orifice is not associated with a selective opening distribution means of the pump or aerosol type for forcing the passage of the cosmetic product through said orifice. The loading of the application member is effected simply by shaking or inverting the reservoir.

This does not prevent the implementation of a selective closure mechanism including sealing the tank when not in use, the passage of the product through the remaining hole not forced.

By "vicinity of a top of the application member", the present application is directed to a top portion extending near the point geometric peak. It can be considered that the orifices are located in an area around the geometric peak representing at most 5% or even 10% of the total surface area of the application surface.

Preferably, the orifices are located at a bottom of the housing corresponding to an absolute peak of the applicator member, preferably only at said bottom.

According to a first variant embodiment, the wall of the housing has a single orifice.

According to a second variant embodiment, the wall of the housing has a plurality of orifices.

The presence of a plurality of orifices makes it possible to keep orifices of relatively small size making it possible to ensure the passage of a quantity of product that is as homogeneous as possible, while ensuring a total passage area sufficient for good loading of the product. application member, after for example only a few stirring movements. In addition, the size of the orifices is also determined according to the size of the solid particles so as to avoid or limit the phenomena of clogging.

In the case of several orifices, the latter are preferably distributed uniformly around the center of the bottom. This ensures optimal loading of the application tip.

Advantageously complementary wall of the housing has a central orifice, located in the center of the bottom. By center of the bottom, we mean the point opposite the geometric top of the applicator.

According to a preferred embodiment, all or part of the orifices have a substantially circular section. Such a circular section is well adapted to prevent clogging phenomena. Where appropriate, depending on the particles used, other sections may be envisaged.

Advantageously complementary, the reservoir comprises at least one mixing element, in particular at least one mixing ball. The characteristics of the mixing element, such as mass or size, will be chosen according to the sedimentation properties of the cosmetic product.

Preferably, the applicator member has an application surface at least partially flocked, preferably completely flocked. In addition to great application softness, flock fibers also help retain particles and improve their diffusion.

Advantageously, the applicator is configured to attach to the container in the absence of use, the applicator member being received in the housing. Thus the applicator makes it possible to close the reservoir.

Preferably, the application surface has no surface, in particular no concavity, capable of forming a space with the housing wall when the applicator member is received in the housing. In particular, the application surface has no concavity opposite the orifices. Indeed, the presence of a concavity would be likely to cause the formation of a cavity between the applicator and the housing partition wall, cavity within which the product could decant, which is not desirable.

Preferably, the applicator member has a generally conical shape, especially with a rounded tip, or hemispherical. Such a shape is particularly suitable for application on the lips.

More preferably, the orifices are closed by the application surface when the applicator is attached to the container. This prevents product leakage through the orifices when the applicator is in the closed position.

Advantageously complementary, the application surface is deformed at least partially against the housing wall when the applicator is attached to the container, the applicator member being slightly compressed. Thus, it is possible, depending on the characteristics of the cosmetic product, to put the applicator member slightly in compression in order to add a pump effect making it possible to facilitate the diffusion of the product and in particular the adsorption of the solvent or oil phase. This compression also improves the closing of the openings by the application member.

The present application also relates to a packaging and application assembly characterized in that the reservoir comprises a liquid cosmetic product containing solid particles, in particular pigments and / or pearlescent agents or even waxes.

In particular, the cosmetic product comprises at least 70% by weight, relative to the weight of the composition, of at least one non-volatile oil of at least one non-volatile oil or of a monophasic mixture of several non-volatile oils, the composition comprising at least one non-volatile hydrocarbon oil, polar or apolar at least one mineral thickener and at least one silicone nonionic surfactant and at least solid particles, colored or uncoloured.

The present invention will be better understood on reading the detailed description which follows, with reference to the appended drawing in which: - Figure 1 is a schematic representation in longitudinal section of a packaging and application assembly according to the invention. FIG. 2 is a diagrammatic representation in longitudinal section of an applicator member equipping the assembly of FIG. 1. FIG. 3 is a diagrammatic representation in longitudinal section of a ring forming a housing for the body of FIG. FIG. 4 is a diagrammatic representation seen from above of the ring of FIG. 3. FIG. 1 shows a set 1 of packaging and application of a liquid cosmetic product P. The set 1 comprises a body 2 forming a reservoir 3 containing a cosmetic product 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 at a free upper end of a neck 24 of the body 2.

The body 2 has a symmetry of revolution. The opening 22 has a circular section. Of course other forms are possible.

The body 2 has at the opening 22, a housing 7 adapted to receive the applicator member 5, said housing 7 being at least partially defined by a partition wall 8 with the reservoir 3.

According to the present application, the partition wall 8 has at least one through-orifice 9 in direct fluid communication with the reservoir 3.

The partition wall 8 may be attached to the tank 3, as illustrated, or be made in one piece by molding with the body of the tank.

In this case, the partition wall 8 is carried by a ring 60 overlying the opening 22.

The ring 60 can be mounted on the body 2 by any means, in particular by clipping or gluing. It can be removable or not.

In this case, the ring 60 is able to engage with the neck 24.

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

The mounting skirt also seals the product.

Alternatively, a ring as shown in Figure 10J of FR 2962890 is also possible. The applicator 4 has superiorly a gripping portion 41 on which the applicator member 5 is mounted.

The gripping portion 41 forms a cap and is adapted to removably engage an upper peripheral wall 63 of the ring 6, thereby closing the reservoir 3 in a sealed manner. More particularly, the peripheral wall 63 of the ring 6 carries an external thread 64 adapted to cooperate with an internal thread 65 complementary to the gripping portion.

In the absence of use, and when the gripping portion 41 is screwed on the ring 6, the applicator member 5 is received in the housing 7 (Figure 1).

According to the present application, the applicator member 5 is made of a porous material with open porosity, for example from a foam.

In particular, the applicator member 5 is made from a polyurethane foam, in particular of the S90 type (DIN 4102-9 standard). The application member 5 is mounted on the gripping portion 41 by any known means, in particular by mounting, clipping or snapping.

In this case, the applicator member 5 has a substantially cylindrical foot 55 which is inserted inside a corresponding chimney 42 of the gripping portion. A bottom wall 43 of the chimney 42 increases the attachment surface. The bottom wall 43 also provides locking in translation. In contrast to 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 free end or rounded tip forming the top 51. In this case, the top 51 is therefore an absolute peak.

The head 56 has a base having a diameter slightly greater than the diameter of the foot 55 and thus has a shoulder 57 adapted to abut against an edge of the chimney 42. This shoulder 57 makes it possible in particular to confer a better resistance to the implementing body.

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

As shown in Figure 1, when the applicator 4 is fixed on the reservoir 3 and the applicator member 5 is in place in the housing, the top 51 is slightly compressed.

It will also be noted that the application surface 51 is flocked. For the application of the floc, a relatively rigid glue may be used after drying. Thus, drying the glue helps to stiffen the application member 5.

As indicated above, the housing 7 is in communication with the interior of the tank 3 via the perforated partition wall 8, through which the orifices 9, open permanently.

According to the present application the orifices 9 are located only at the level of at least one bottom of the housing facing the vicinity of the top 51 of the applicator member 5 when said applicator member 5 is in place in the housing 7 body 2 forming reservoir 3.

In this case, the wall 8 has three orifices 9. The orifices 9 are regularly distributed near and around the center of the bottom of the wall 8. The orifices have a substantially circular section. In this case, the diameter of the orifices is 1.5mm.

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

The center of each orifice 9 is located at a distance of 4.5 mm from the center of the bottom corresponding to the top 51 of the applicator member. Preferably, the orifices are located less than 5 mm from the center of the bottom. The applicator member 5 advantageously closes all the orifices of the wall 8 when the applicator 4 is in place on the reservoir 3. This may be useful to prevent an excess of product from spreading in the housing while the applicator closes this one.

Advantageously, the reservoir 3 comprises at least one mixing element, in particular at least one mixing ball (not shown). During agitation or overturning, the ball makes it possible to facilitate the homogenization of the product or even the resuspension of the particles, if necessary.

According to one embodiment, the reservoir comprises a liquid cosmetic product containing solid particles, in particular pigments and / or pearlescent agents.

PREFERENTIALLY ASSOCIATED COSMETIC COMPOSITION

As indicated above, the cosmetic product (composition) is in the form of a liquid at room temperature (25 ° C.) and atmospheric pressure (1.013 × 10 5 Pa). More particularly, the viscosity of the composition varies between 0.2 and 0.8 Pa s, preferably between 0.3 and 0.7 Pa.s. The measurement of the viscosity is generally carried out at 25 ° C., using a RHEOMAT RM 180 viscometer equipped with a mobile No. 2, the measurement being carried out after 10 minutes of rotation of the mobile within the composition ( time at the end of which there is a stabilization of the viscosity and the speed of rotation of the mobile) at 200 revolutions / min (rpm).

NON-VOLATILE OILS

The composition therefore comprises at least 70% by weight, relative to the weight of the composition, of at least one non-volatile oil or of a monophasic mixture of several non-volatile oils, at least one of which is chosen from hydrocarbon oils, polar or apolar.

The mixture is said to be monophasic when phase separation is not observed with the eye or phase contrast microscope at room temperature (25 ° C) after temperature homogenization and Rayneri mixing (550 rpm). min, 10 minutes) and storage in a closed container at room temperature for 24 hours (and atmospheric pressure). Under these conditions, we speak of a stable monophasic mixture.

More particularly, the word "oil" means, within the meaning of the invention, non-aqueous compounds, liquid at 25 ° C and atmospheric pressure (1.013 105 Pa), immiscible with water. By "immiscible" it is meant that mixing the same amount of water and oil, after mixing (eg Rayneri 550 rpm, 10 minutes) does not lead to a stable solution comprising only one phase under normal conditions of temperature and pressure.

The term "non-volatile oil" means an oil whose vapor pressure at 25 ° C. and atmospheric pressure is non-zero and less than 0.02 mmHg (2.66 Pa) and better still less than 10'3 mm. Hg (0.13 Pa).

By "hydrocarbon oil" is meant an oil formed essentially, or even constituted, of carbon and hydrogen atoms, and possibly of oxygen, nitrogen, and not containing a silicon atom or fluorine.

For the purposes of the present invention, the term "apolar oil" means an oil chosen from hydrocarbons, that is to say from compounds comprising only carbon and hydrogen atoms.

Non-volatile non-volatile hydrocarbon oils

These oils can be of vegetable, mineral or synthetic origin.

More particularly, the non-volatile non-volatile hydrocarbon oils may be chosen from linear or branched hydrocarbons of mineral or synthetic origin.

For example, suitable for carrying out the present invention are: - paraffin oils, - squalane, - isohexadecane - isoeicosane, - naphthalene oil, - polybutenes such as for example INDOPOL H- 100 (molar mass or MW = 965 g / mol), INDOPOL H-300 (MW = 1340 g / mol), INDOPOL H-1500 (MW = 2160 g / mol) marketed or manufactured by AMOCO, polyisobutenes, hydrogenated polyisobutenes such as, for example, Parleam® sold by the company Nippon Oil Fats, PANALANE H-300 E marketed or manufactured by AMOCO (MW = 1340 g / mol), Viseal 20000 sold or manufactured by the company SYNTEAL (MW = 6000 g / mol), the REWOPAL PIB 1000 marketed or manufactured by WITCO (MW = 1000 g / mol), or the PARLEAM LITE marketed by NOF Corporation, - the decene / butene copolymers, polybutene / polyisobutene copolymers, in particular Indopol L-14,

hydrogenated polydecenes and polydecenes, such as for example: PURE YN 10 (MW = 723 g / mol), PURES YN 150 (MW = 9200 g / mol) marketed or manufactured by the company MOBIL CHEMICALS, or else PURESYN 6 marketed by EXXONMOBIL CHEMICALL - and their mixtures.

Nonvolatile oils with polar hydrocarbons

These polar hydrocarbon oils are therefore formed of carbon and hydrogen atoms, and comprise at least one or more oxygen and nitrogen atoms, but without silicon or fluorine atoms.

They therefore contain at least one group chosen from alcohol, ester, ether, carboxylic acid, amine and / or amide functions.

Preferably, the non-volatile polar hydrocarbon oils are free, in addition to silicon, of fluorine; heteroatoms such as nitrogen and phosphorus.

In the present case, the non-volatile hydrocarbon-based polar oils thus comprise one or more oxygen atoms as a heteroatom.

In particular, the non-volatile hydrocarbon-based polar oils comprise at least one alcohol function (it is then an "alcohol oil") or at least one ester function (it is then an "ester oil" ). It should be noted that the ester oils may in particular be hydroxylated.

The composition may comprise one or more non-volatile hydrocarbon oils, in particular chosen from: - C 1 -C 4 - especially C 10 -C 24 and preferably C 12 -C 22 alcohols, saturated or unsaturated, branched or unbranched, more particularly monoalcohols.

Advantageously, the C 10 -C 26 alcohols are fatty monoalcohols, preferably branched when they comprise at least 16 carbon atoms. As examples of fatty alcohols that may be used, mention may be made of linear or branched fatty alcohols, of synthetic origin, or even natural, such as, for example, alcohols derived from vegetable matter (copra, palm kernel, palm, etc.). or animal (tallow ...).

Of course, other long-chain alcohols may also be used, such as, for example, ether-alcohols or even so-called Guerbet alcohols.

Finally, it is also possible to use certain longer or shorter cuts of alcohols of natural origin, such as, for example, coco (C12-C18) or tallow (C16-C18) or diol or cholesterol-type compounds. As particular examples of fatty alcohols that may be used as preferred, mention may be made especially of lauryl alcohol, isostearyl alcohol, oleic alcohol, 2-butyloctanol, 2-undecyl pentadecanol, 2-hexyldecyl alcohol and isoketyl alcohol. octyldodecanol and their mixtures.

According to an advantageous embodiment, the alcohol is octyldodecanol. - the monoesters. the diesters. tri esters, optionally hydroxylated. of a mono- or polycarboxylic acid having 1 to 5 carbon atoms and an alcohol in CVCs.

In particular: monoesters of a C2-C8 carboxylic acid and a C2-C8 alcohol, optionally hydroxylated, diesters of a C2-C8 dicarboxylic acid and of a C2-C8 alcohol, optionally hydroxylated; such as, for example, diisopropyl adipate, diethyl-2-hexyl adipate, dibutyl adipate, or 2-diethylhexyl succinate, triesters of a C2-C8 triacidic acid and a C2-C8 alcohol. optionally hydroxylated, such as, for example, citric acid esters, such as trioctyl citrate, triethyl citrate, acetyl tributyl citrate, tributyl citrate, acetyl tributyl citrate, esters of a C 1 -C 10 polvol and one or more C2-Cs carboxylic acids, such as glycol and monoacid diesters, such as in particular neopentyl glycol diheptanoate, propylene glycol dioctanoate, or triesters of glycerol and monoacids such as triacetin. ester oils, in particular before at least 18 carbon atoms and even more particularly between 18 and 70 carbon atoms. By way of examples, mention may be made of mono-, di- or tri-esters.

The ester oils may be hydroxylated or not.

Thus, the non-volatile ester oil may be chosen for example from: monoesters comprising at least 18 carbon atoms and even more particularly having between 18 and 40 carbon atoms in total, in particular monoesters, of formula R 1 COOR 2 in which R 1 represents the residue of a linear or branched or aromatic fatty acid comprising from 4 to 35 carbon atoms, saturated or unsaturated, and R 2 represents a particularly branched hydrocarbon-based chain containing from 4 to 35 carbon atoms, provided that the sum of the atoms carbon of the radicals R 1 and R 2 is greater than or equal to 18, such as, for example, purcellin oil (cetostearyl octanoate); isononyl isononanoate; 2-hexyl ethyl palmitate; octyledodecyl neopentanoate; octyl-2 dodecyl stearate; 2-octyl dodecyl erucate; isostearyl isostearate; C12-C15 alkyl benzoate, such as octyl-2-dodecyl benzoate; octanoates, decanoates or ricinoleates of alcohols or polyalcohols; isopropyl myristate; isopropyl palmitate; butyl stearate; hexyl laurate; 2-ethylhexyl palmitate; 2-hexyl decyl laurate; 2-octyl decyl palmitate; 2-octyldodecyl myristate.

R 1 and R 2 are such that the sum of the carbon atoms of the radicals R 1 and R 2 is greater than or equal to 18. The monoesters, in particular having at least 18 carbon atoms and even more particularly from 18 to 22 carbon atoms, fatty acid such as in particular lanolic acid, oleic acid, lauric acid, stearic acid, and diols such as glycols, such as propylene glycol monoisostearate. diesters, especially having at least 18 carbon atoms and even more particularly comprising between 18 and 60 carbon atoms in total, in particular between 18 and 50 carbon atoms in total. It is possible in particular to use diesters of dicarboxylic acid and of monoalcohols comprising more than 8 carbon atoms, such as, preferably, diisostearyl malate, diisostearyl adipate; or the diesters of glycol and of monocarboxylic acids, such as, for example, neopentyl glycol diheptanoate or diethylene glycol diisononanoate; or 2-polyglyceryl diisostearate (especially such as the compound sold under the commercial reference DERMOL DGDIS by Akzo). hydroxylated monoesters and diesters, preferably having a total carbon number of at least 18 carbon atoms and even more particularly ranging from 18 to 70, such as, in particular, polyglyceryl-3-diisostearate, isostearyl lactate, octylhydroxystearate, octyldodecyl hydroxystearate, diisostearyl malate, glycerine stearate. the triesters, in particular having at least 35 carbon atoms and even more particularly comprising between 35 and 70 carbon atoms in total, in particular such as tri tries of carboxylic triacid, such as for example triisostearyl citrate, or tridecyl trimellitate, or triesters of glycerol and mono carboxylic acids such as polyglycerol-2 triisostearate. tetraesters, in particular having at least 35 carbon atoms and even more particularly having a total number of carbon ranging from 35 to 70, such as, for example, the tetraesters of penthaerythritol or of polyglycerol and of a monocarboxylic acid, for example such that for example, pentaerythrityl tetrapelargonate, tetraisostearate pentaerythrityl, pentaerythrityl tetraisonanoate, glyceryl tri-2-tetradecanoate, polyglyceryl-2 tetraisostearate or pentaerythrityl tetra decyl-2 tetradecanoate. the polyesters obtained by condensation of dimer and / or trimer of unsaturated fatty acid and of diols such as those described in the patent application FR 0 853 634.

Preferably, the composition according to the invention comprises at least one silicone polymer with a content, expressed as active polymer material, of 0.1 to 4% by weight, preferably of 0.2 to 3% by weight, by weight. relative to the weight of the composition.

Additives

The composition may also comprise additional cosmetic ingredients conventionally used in compositions intended for the treatment of the lips. By way of examples, particular mention may be made of active ingredients such as, for example, plant extracts which are preferably soluble in the composition, non-volatile silicone oils, phenylated or non-phenylated, which do not lead to a monophasic mixture with the non-oil. volatile or the mixture of non-volatile oils previously mentioned (conditions detailed above), preservatives, antioxidants, sweeteners, fragrances, sunscreens, bactericides, fat-soluble dyes, and mixtures thereof.

Of course, those skilled in the art will take care to choose any additional ingredients and / or their amount in such a way that the advantageous properties of the composition are not or not substantially impaired by the addition envisaged. As an illustration, the additive contents are those conventionally used in the field under consideration, and for example vary from 0.01 to 5% by weight relative to the weight of the composition.

It should be noted that if one of the additives is a non-volatile oil, or several of them, then the total content of non-volatile oils present in the composition advantageously remains in the ranges detailed above. The use of the set 1 of packaging and application is carried out as follows. Since the assembly 1 is in a closed configuration, the user shakes or returns the assembly, in particular with the aim of homogenizing the cosmetic product.

In doing so, the product is projected through the orifices 9 of the partition wall 8 and impregnates very locally 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 gripping portion 41 and disengages it from the reservoir 3. In doing so, the applicator member 5 is extracted from the housing 7 and the surface application is accessible to the user who can then proceed to the application.

To do this, it brings the top portion of the applicator member into contact with the application surface to be covered, for example a surface of the lips, to deposit a layer of cosmetic product.

If necessary, it can use a lateral portion of the application surface to fade or spread the product.
