Abstract

The invention relates to a cosmetic composition which is used as make-up for and/or to care for the lips. The inventive composition comprises at least one cosmetically-acceptable organic liquid medium and a dispersion of a grafted ethylene polymer. Said polymer is such that, when a sufficient quantity thereof is dispersed in the composition, the latter can form a deposit with a transfer of less than or equal to 35 %.

Description

cosmetic composition comprising a non-transfer dispersion of a grafted ethylenic polymer

The present invention relates to a cosmetic composition for making up and / or caring for the lips comprising a dispersion of a grafted ethylenic polymer in a liquid fatty phase to be applied to lips.

The composition according to the invention may be a makeup composition or a care composition, preferably a makeup composition.

The lipstick compositions are commonly used to give an aesthetic color to the lips. These makeup products generally contain fatty phases such as waxes and oils, pigments and / or fillers and optionally additives such as cosmetic or dermatological active agents.

These compositions, when applied to the lips, exhibit the disadvantage of transferring, ie to deposit at least in part, leaving traces on certain substrates with which they can be contacted and in particular a glass, a cup, a cigarette, an item of clothing or the skin. This results in mediocre persistence of the applied film, requiring regular renewal application of the composition of lipstick.

therefore sought makeup compositions for the lips say "transfer" which have the advantage of forming a deposit that is not deposited, at least partly, on the supports with which they come into contact (glass, clothing, cigarette tissue).

To limit the transfer of cosmetic compositions, it is known to use volatile oils, especially at higher levels to 40% by weight. These volatile oils present in large quantities make the make-up product, including lipstick, uncomfortable for the user: the makeup deposit gives a sensation of dryness and tightness. It is also known products as two separate compositions to apply one to the other on the lips for a makeup free transfer. For example, the product Lipfinity MAX FACTOR as described in WO 97/17057 is a product comprising two compositions to be applied successively: the base composition contains a silicone resin and volatile oils, and surface composition (so-called topcoat ) contains a sucrose ester. However, the application of two compositions for makeup can be prohibitive for some users.

The present invention aims to provide a new formulation route for a cosmetic composition, especially a lip makeup, to obtain a deposit having good properties of non-transfer, including without using a high rate of volatile oils, said deposition can be obtained with this single composition. The invention also aims to provide a cosmetic composition, in particular a lip makeup, to obtain a deposit on the lips comfortable. The inventors have discovered that it is possible to obtain such a composition by using a dispersion of a particular graft polymer in a liquid fatty phase. The composition provides a deposit, especially a lip makeup, with good non-transfer properties. In addition, the deposit obtained on the lips causes no sensation of dryness or tautness to the user: the deposit is comfortable.

More specifically, the present invention therefore relates to a cosmetic composition comprising a polymer dispersion as described below, the composition being such as defined below.

A first object of the invention is a cosmetic composition for making up and / or caring for the lips containing a dispersion in a liquid fatty phase, particles, preferably solid particles, of a grafted ethylenic polymer, said polymer being such that when dispersed in sufficient amount in the composition, the latter is advantageously adapted to form a deposit having a lower transfer or equal to 35%.

Also advantageously, the composition according to the invention is capable of forming a deposit having a lower transfer or equal to 30%, preferably less than or equal to 25%, preferably less than or equal to 20%, preferably less than or equal to 15 %, preferably less than or equal to 10%, preferably less than or equal to 5%.

The invention also relates to a cosmetic process or for the nontherapeutic care of the lips, comprising the application to the lips of a composition as defined above.

The invention also relates to the use of a composition as defined above to obtain a deposit not transfer, including a make-up on non-transfer lips.

The invention also relates to the use of a grafted ethylenic polymer, dispersed in a liquid fatty phase, in a cosmetic composition for obtaining a deposit, especially a make-up of lips, not transfer. The invention also relates to the use, in a cosmetic composition, of a sufficient amount of a dispersion in a liquid fatty phase, of a grafted ethylenic polymer, to obtain a deposit on the lips having a lower transfer or equal to 35%. The transfer of the deposit obtained with the composition according to the invention is determined according to the protocol described below.

Preheating a support (rectangle of 40 mm X 70 mm and 3 mm thick) of adhesive polyethylene on one side having a foam density of 33 kg / m3 (sold under the name RE40X70EP3 from the company Joint Technique Lyonnais Ind) on a hot plate maintained at a temperature of 40 ° C so that the support surface is maintained at a temperature of 33 ° C ± 1 ° C. While leaving the support on the hotplate, the composition is applied over the entire non-adhesive surface of the support by spreading it using a brush to obtain a deposit of the composition of about 15 microns and allowed to dry during 30 minutes. After drying, the carrier is bonded via its adhesive face onto an anvil of diameter 20 mm and provided with a screw thread. The whole depot carrier is then cut using a hollow punch with a diameter of 18 mm. The anvil is then screwed onto a press (STATIF MANUAL Imada SV-2 from the company Someco) equipped with a tensile testing machine (Imada DPS-20 from the company Someco).

A white photocopier paper 80g / m2 is placed on the bed of the press and the assembly is pressed support / deposit on the paper at a pressure of 2.5 kg for 30 seconds. After removing the support / deposit assembly, some of the deposit transferred onto the paper. then measuring the color of the deposit transferred onto the paper using a MINOLTA CR300 colorimeter, the color being characterized by the colorimetric parameters L *, a *, b *. colorimetric parameters are determined o L *, a * o b * o the color of the plain paper used.

It then determines the difference in color between ΔE1 the color of the deposit transferred relative to the color of the plain paper by the following equation.

= V (L * -L * 0) 2 + (a * - a 0 * P + (b * - b * 0) 2

ΔE1

Furthermore, preparing a total transfer reference by applying the composition directly onto a paper identical to the one used previously, at room temperature (25 ° C), by spreading the composition using a brush and to obtain a depositing the composition of about 15 .mu.m and dried for 30 minutes at room temperature (25 ° C). After drying, the colorimetric parameters are directly measured L * ', a *', b * 'of the color of the deposit placed on the paper, corresponding to the total transfer reference color. It determines the colorimetric parameters L * 'Q, a * o b * o the color of the plain paper used.

It then determines the difference in color between ΔE2 total transfer reference color compared to the color of plain paper by the following equation.

ΛE2 = UL * '-L 0 + (a *' - 0 + (b * '- b0

The transfer of the composition, expressed as a percentage, is the ratio

100 X ΔE1 / ΔE2 The measurement is performed on 4 supports in succession and the transfer value corresponds to the mean of the 4 measurements obtained with the 4 supports. The composition according to invention comprises a dispersion of particles, preferably solid particles, of a grafted ethylenic polymer in a liquid fatty phase.

The term "ethylenic polymer" means a polymer obtained by polymerizing monomers comprising an ethylenic unsaturation.

The dispersion of grafted ethylenic polymer is free of separate stabilizing polymer of said graft polymer, such as those described in EP749747, and the particles of grafted ethylenic polymer are therefore not surface-stabilized with such additional stabilizing polymers. The graft polymer is dispersed in the liquid fatty phase in the absence of additional stabilizer the particle surface.

By graft polymer means a polymer having a backbone comprising at least one pendant side chain or located at the chain end, and preferably pending.

Advantageously, the grafted ethylenic polymer comprises an ethylenic backbone insoluble in the said liquid fatty phase, and side chains covalently bound to said backbone and soluble in the said fatty phase.

The grafted ethylenic polymer is an uncrosslinked polymer. In particular, the polymer is obtained by polymerising monomers comprising one polymerizable group.

Preferably, the grafted ethylenic polymer is a film-forming polymer. Per polymer "film-forming" means a polymer capable, by itself or in the presence of an auxiliary film-forming agent, a continuous film, in particular to the touch and / or to the naked eye, and adheres to a support, in particular on keratin materials.

According to one embodiment of the invention, the grafted ethylenic polymer is a grafted acrylic polymer. The grafted ethylenic polymer is obtainable by radical polymerization in an organic polymerization medium: - at least one ethylenic monomer, in particular of at least one acrylic monomer and optionally at least one vinyl monomer having no additional acrylic pourTormer said insoluble skeleton; and "- at least one macromonomer comprising a polymerizable end group to form the side chains, the said macromonomer having an average molecular weight of greater than or equal to 200 and the proportion of polymerized macromonomer representing from 0.05 to 20% by weight of the polymer. the environment in which the graft polymer is provided in view of its formulation, called liquid organic dispersion medium may be the same to the polymerization medium.

However, the polymerization medium can be substituted in whole or part with another liquid organic medium. This other liquid organic medium may be added after polymerization, to the polymerization medium. This is then evaporated in whole or part.

The liquid fatty phase of the cosmetic composition may contain the organic polymerization medium.

The liquid fatty phase may contain liquid organic compounds other than those present in the dispersion medium. These other compounds are chosen so that the graft polymer remains in the state of dispersion in the liquid fatty phase.

The organic liquid dispersion medium is present in the liquid fatty phase of the composition according to the invention due to the introduction into the composition of the graft polymer dispersion obtained. The liquid fatty phase:

The liquid fatty phase preferably comprises predominantly one or more liquid organic compounds (or oils) as defined below. In particular, the liquid fatty phase is a non-aqueous liquid organic phase not miscible with water at room temperature (25 ° C).

Thanks to the above characteristics, in an organic medium of given dispersion polymers have the ability to fold on themselves, thus forming substantially spherical particles, with the periphery of these particles having the deployed side chains, which ensure the stability of these particles. Such particles resulting from the characteristics of the graft polymer has the particularity of not agglomerating in the said medium and therefore being self-stabilized and form a particularly stable dispersion of polymer particles.

In particular, the grafted ethylenic polymers of the dispersion can form nanoscale particles of average size ranging from 10 to 400 nm, preferably from 20 to 200 nm.

Due to this very small size, the graft polymer particles in dispersion are particularly stable and therefore unlikely to form agglomerates.

The graft polymer dispersion may be a stable dispersion and not form sediments when placed over a prolonged period (e.g. 24 hours) at room temperature (25 ° C).

Preferably, the dispersion of grafted polymer particles has a solids content (or dry extract) of polymer ranging from 40% to 70% by weight of solids and especially from 45% to 65% by weight. the polymer dispersion particles grafted with a method can be prepared comprising a step of free-radical copolymerization, in an organic polymerization medium, one or more acrylic monomers as defined above with one or, more macromonomers as defined above. As indicated above, the liquid organic dispersion medium may be the same or different from the polymerization medium.

Conventionally, the copolymerization can be conducted in the presence of a polymerization initiator. The polymerization initiators may be free radical initiators. Generally, such a polymerization initiator can be selected from organic peroxy compounds such as dilauroyl peroxide, dibenzoyl peroxide, tert-butyl peroxy-2- ethylhexanoate; diazo compounds such as azobisisobutyronitrile, azobisdiméthylvalero nitrile. The reaction may also be initiated using photoinitiators or with radiation such as UV, neutrons or plasma.

In general, to implement this method, are introduced into a suitably sized reactor to the amount of polymer which will perform at least part of the organic polymerization medium, part of the acrylic monomers and / or additional vinyl, which will, after polymerization, the insoluble skeleton, all of the macromonomer (which will constitute the side chains of the polymer) and a portion of the polymerization initiator. At this point of introduction, the reaction medium forms a relatively homogeneous medium. The reaction medium is then stirred and heated to a temperature to obtain polymerization of the monomers and macromonomers. After some time, the initially homogeneous and clear medium leads to dispersion of milky appearance. Then a mixture consisting of the remaining part of the monomers and the polymerization initiator. After an adequate time during which the mixture is heated under stirring, the medium stabilizes in the form of a milky dispersion, the dispersion comprising polymer particles stabilized in the medium in which they were created, the said stabilization being due to the presence in the polymer, soluble side chains in said dispersion medium.

The polymer dispersion may be present in an amount of 3 to 95% by weight in the composition, especially from 4 to 90% by weight or even from 20 to 70% by weight.

The graft polymer may be present in the composition according to the invention in a solids content (or active material) from 1 to 66.5% by weight relative to the total weight of the composition, preferably ranging from 6 to 45 % and more preferably from 8 to 40% by weight.

The present examples illustrate the preparation of polymers according to the invention, capable of forming a particle dispersion in an organic medium under consideration.

In these examples, it is determined, after preparation of said dispersion, the weight average molecular weight (Mw) and number (Mn) of the polymer, the glass transition temperature of the polymer, the solids content (or dry extract) of the dispersion and the size of the polymer particles.

The weight average molecular weight (Mw) and number (Mn) are determined by liquid chromatography by gel permeation (THF solvent, calibration curve established with linear polystyrene standards, refractometric detector). The measurement of the glass transition temperature (Tg) is performed according to ASTM D3418-97, by differential scanning calorimetry (DSC "Differential Scanning Calorimetry") on a calorimeter, over a temperature range between -100 ° C and +150 ° C at a heating rate of 10 ° C / min in aluminum crucibles of 150 .mu.l.

Preparing crucibles are as follows: in an aluminum crucible of 150 .mu.l was charged with 100 .mu.l of the resulting dispersion and the solvent is allowed to evaporate for 24 hours at room temperature and 50% relative humidity. The operation is repeated then introduced the crucible in the Mettler DSC30 calorimeter.

Dry matter content (or dry extract), i.e. the non-volatile content, can be measured in several ways: there may be mentioned, for example, methods by oven drying or drying methods by exposure to infrared radiation.

Preferably, the dry matter content is measured by heating the sample with infrared rays of 2 .mu.m to 3.5 .mu.m wavelength. The substances contained in the composition that have a high vapor pressure evaporate under the effect of this radiation. The measurement of sample weight loss is used to determine the solids content of the composition. These measurements are performed using an LP16 commercial infrared desiccator from Mettler. This technique is fully described in the machine documentation supplied by Mettler. The measurement protocol is the following: is spread about 1 g of the composition to a metal cup. The latter, after introduction into the dryer, is subjected to a set temperature of 120 ° C for one hour. The wet mass of the sample, corresponding to the initial mass and dry mass of the sample, corresponding to the mass after exposure to radiation, are measured by means of a precision balance.

The dry matter content is determined as follows: Solids = 100 x (dry / wet weight mass).

The particle sizes can be measured by different techniques include in particular light scattering techniques (dynamic and static), Coulter counter methods, measurements by sedimentation rate (linked to the size via the law Stokes) and microscopy. These techniques can measure a particle diameter and for some of them a particle size distribution. Preferably, the sizes and size distributions of particles of the compositions of the invention are measured by static light scattering using a commercial granulometer MasterSizer 2000 from Malvern. The data are processed on the basis of. theory djffusjoji te_Mie .._. This theory, exact for isotropic particles, to determine in the case of non-spherical particles, an "effective" diameter particles. This theory is described especially in the Van de Hulst, HC, "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957. The composition is characterized by its "effective" diameter by volume D [4,3], defined as follows: where V represents the volume of dj effective particle diameter. This setting is particularly described in the technical documentation of the granulometer. The measurements are performed at 25 ° C, on a dilute particle dispersion obtained from the composition as follows: 1) dilution by a factor of 100 with water, 2) homogenization of the solution, 3) rest of the solution for 18 hours, 4) recovering the supernatant whitish homogeneous.

The hardness is measured according to a method of penetration of a probe into a sample of compound and in particular using a texture analyzer (for example TA-XT2i from Rheo) equipped with a stainless steel cylinder of 2 mm in diameter. The hardness measurement is carried out at 20 ° C at the center of 5 samples. The cylinder is introduced into each sample at a pre-speed of 1 mm / s and then at a speed is 0.1 mm / s, the penetration depth being 0.3 mm. The measured hardness value is that of the maximum peak. The liquid fraction of the pasty compound measured at 23 ° C is preferably 9 to 97% by weight of the compound. This liquid fraction at 23 ° C is preferably between 15 and 85%, more preferably between 40 and 85% by weight. The liquid fraction by weight of the pasty compound at 23 ° C is equal to the ratio of the enthalpy of fusion consumed at 23 ° C on the heat of fusion of the pasty compound. The enthalpy of fusion of the pasty compound is the heat consumed by the compound to change from the solid state to the liquid state. The pasty compound is said to the solid state when the whole of its mass is in solid crystalline form. The pasty compound is said in the liquid state when the whole of its mass is in liquid form. The enthalpy of fusion of the pasty compound is equal to the area under the curve of the thermogram obtained using a differential scanning calorimeter (DSC), such as the calorimeter sold under the name MDSC 2920 by the company TA instrument, with a temperature rise of 5 or 10 ° C per minute according to ISO 11357-3: 1999. The enthalpy of fusion of the pasty compound is the amount of energy needed to make the compound from the solid state to the liquid state. It is expressed in J / g.

The enthalpy of fusion consumed at 23 ° C is the amount of energy absorbed by the sample to pass from the solid state to the state that it has at 23 ° C consisting of a liquid fraction and a solid fraction. The liquid fraction of the pasty compound measured at 32 ° C is preferably 30 to 100% by weight of the compound, preferably 80 to 100%, more preferably from 90 to 100% by weight of the compound. When the liquid fraction of the pasty compound measured at 32 ° C is 100%, the temperature of the end of [a_ melting range of the pasty compound is less than or brighten at 32 ° C. The liquid fraction of the pasty compound measured at 32 ° C is equal to the ratio of the enthalpy of fusion consumed at 32 ° C on the heat of fusion of the pasty compound. The enthalpy of fusion consumed at 32 ° C is calculated in the same way as the enthalpy of fusion consumed at 23 ° C.
