Description

[0001] The present invention relates to a cosmetic makeup or skin care composition, including the scalp, both of the face and of the human body, of the lips or of the slams of human beings, such as hair , eyelashes or eyebrows, which includes a cosmetically acceptable organic liquid medium and a particular sequenced polymer. [0002] The makeup compositions for the lips and skin called "no transfer" are compositions that have the advantage of forming a deposit that does not transfer or leaves no traces or marks, at least in part, on the supports with which they enter contact (glass, clothing, cigarette, tissues). [0003] The known non-transfer compositions are based on silicone resins and volatile silicone oils and, even having improved persistence properties, have the disadvantage of leaving on the skin and lips, after evaporation of volatile silicone oils, a film that becomes uncomfortable over time (feeling of drying and tightness) and not very bright.

Now, women are currently looking for products, especially lip or eyelid coloration, bright and at the same time without transfer. [0004] A cosmetic product that is at the same time of good persistence, without transfer and bright is still needed. [0005] It was proposed in the prior art, in the patent application WO-A-97/17057 of the company Procter & Gamble, a method to increase the brightness and comfort of compositions without transfer, consisting of applying two compositions one envelope the other. However, these products remain uncomfortable. In addition, the application of two compositions may be unacceptable for some consumers. [0006] The purpose of the present invention is to propose a new way of formulating a cosmetic product, in particular a make-up product, which allows good properties of "no transfer" and gloss. [0007] This product especially has the advantage of not including more than a single composition, contrary to the product of the application WO-A-97/17057. [0008] The product obtained according to the invention, especially when it is a product intended for the lips, has good properties of absence of migration, persistence and absence of desiccation. [0009] A subject of the invention is a bright and non-transfer composition of care or makeup of the skin and / or lips and / or the faneras, which contains a film-forming linear sequential ethylenic polymer as defined below. Surprisingly, the inventors saw that the use of such a sequenced polymer allowed to obtain a bright composition, without transfer. The composition according to the invention also has the advantage of having a good persistence. [0010] The composition of the invention may in particular constitute a hair product or a make-up product of the body, lips or slanes of human beings with care and / or treatment properties. It is especially a lipstick or lip gloss, an eye shadow, a tattoo product, a mascara, an eyeliner, a product of artificial tanning of the skin, a care cream or eventually protective color or a coloring product

or hair care. [0011] More precisely, the invention aims at a cosmetic composition containing a cosmetically acceptable organic liquid medium and a film-forming linear ethylenic sequencing polymer, the polymer of which is such that, when it is in sufficient quantity in the composition,

-

the average brightness at 20 ° of a deposit of said composition, once extended on a support, is greater than or equal to 30 over 100, and

-

the transfer rate is less than or equal to 40 out of 100,

said first and second sequenced polymer containing sequences linked together by a statistical intermediate segment that includes at least one constituent monomer of the first sequence and at least one constituent monomer of the second sequence,

the first polymer sequence being selected from:

-

 a) a sequence that has a Tg greater than or equal to 40 ° C,

-

 b) a sequence that has a Tg less than or equal to 20 ° C and

-c) a sequence having a Tg between 20 and 40 ° C,

and the second sequence being selected within a category a), b) or c) different from the first sequence,

and said sequenced polymer having a polydispersity index I greater than or equal to 2.8. [0012] U.S. Patent 6,153,206 describes a cosmetic composition that includes a polymer containing repetitive units having a Tg of -10 to 75 ° C and repetitive units having a Tg of 76 to 120 ° C. It also describes block polymers comprising polymethyl methacrylate blocks and polyisobutyl methacrylate blocks, and also triblock polymers comprising polymethyl methacrylate blocks, polyisobutyl methacrylate blocks and ethyl methacrylate blocks. FR-A-2,809,306 and WO 03/046032 describe cosmetic compositions that include a sequenced ethylene polymer. In the examples, the only exemplified polymer has a polydispersity index respectively equal to 2.2 and 1.16.

Application FR 2,803,743 describes a cosmetic composition containing an aqueous dispersion of hydrophobic polymer particles with a core / cortex structure. The latex prepared in Example 1 comprises a core obtained by polymerization of butyl acrylate, methyl methacrylate and butanediol diacrylate, thus forming a non-linear crosslinked polymer, and with a conversion ratio equal to 98.4%. The bark is obtained by polymerization of methyl methacrylate and methacrylic acid. [0013] Preferably, the composition according to the invention is a composition without rinsing. [0014] The invention also relates to a cosmetic composition that includes an organic liquid medium and at least one sequenced polymer as described below. Average brightness of the composition [0015] By "medium brightness", the brightness is designated as can be measured with a brightness meter in a conventional manner by the following method.

On a contrast card of LENETA brand and reference FORM 1A PENOPAC, a layer between 50 m and 150 m thick of the composition is spread with an automatic extender. The layer covers at least the white background of the cardboard. The tank is allowed to dry for 24 hours and has a temperature of 30 ° C and then the brightness measurement is carried out at 20 ° on the white background with a BYK GARDNER brand and a micro-TRIGLOSS reference brightness meter.

This measurement is repeated (between 0 and 100) at least three times and the average brightness is the average of the at least three measurements made. [0016] The average brightness of the composition measured at 20 ° is advantageously greater than or equal to 30, better still higher

or equal to 35, better still greater than or equal to 40, better still greater than or equal to 45, better even greater than or equal to 50 over 100, better still greater than or equal to 55, better still greater than or equal to 60. [0017] Preferably, the average brightness of the composition, once extended on a support, measured at 60 °, is greater than or equal to 50, better still greater than or equal to 60, better still greater than or equal to 65, better still greater than or equal to 70 , better still greater than or equal to 75, better still greater than or equal to 80, better still greater than or equal to 85 or better still

greater than or equal to 90 over 100. [0018] The measurement of the average brightness at 60º is carried out as follows. The brightness can be measured with a brightness meter conventionally by the following method.

On a contrast card of LENETA brand and reference FORM 1A PENOPAC, a layer between 50 m and 150 m thick of the composition is spread with an automatic extender. The layer covers at least the white background of the cardboard. The tank is allowed to dry 24 hours at a temperature of 30 ° C and then the brightness measurement at 60 ° is then carried out on the white background with a BYK GARDNER brand and a micro-TRIGLOSS reference brightness meter.

This measurement is repeated (between 0 and 100) at least three times and the average brightness is the average of the at least three measurements made. [0019] According to one embodiment, the average brightness of the composition measured at 20 ° is preferably higher

or equal to 35, preferably 40, 45 or 50 over 100, and / or the average brightness of the composition measured at 60 ° is preferably greater than or equal to 65, 70 or 75 over 100. In this embodiment, the composition advantageously constitutes a liquid lipstick. Transfer index of the composition [0020] The transfer index of the composition according to the invention is preferably less than or equal to 40 over 100. Preferably still, the transfer index is less than or equal to 30, preferably less than or equal to 20, preferably still less than or equal to 15, preferably less than or equal to 10, preferably less than or equal to 5 over 100, preferably less than or equal to 2 over 100. [0021] The transfer rate can be measured according to the following method. [0022] A support (rectangle of 40 mm X 70 mm and 3 mm thick) of adhesive polyethylene foam is preheated on one of the faces having a density of 33 kg / m3 (sold under the name RE40X70EP3 of the company JOINT TECHNIQUE LYONNAIS IND) on a maintained heating plate has a temperature of 40 ° C to maintain the surface of the support has a temperature of 33 ° C  1 ° C. [0023] Leaving the support on the heating plate, the composition is applied over the entire non-adhesive surface of the support by extending it with a brush to obtain a deposit of the composition of approximately 15 µm and then allowed to dry for 30 minutes. [0024] After drying, the support is glued on its adhesive face on an anvil 20 mm in diameter and equipped with a screw passage. The support / tank assembly is then trimmed using an 18 mm diameter punch. The anvil is then screwed onto a press ((STATIF MANUEL IMADA SV-2 of the company SOMECO) equipped with a dynamometer (IMADA DPS-20 of the company SOMECO). [0025] A white paper for photocopier of 80 g / m2 on the press base and then the support / reservoir assembly on the paper is pressed at a pressure of 2.5 kg for 30 seconds After removing the support / reservoir assembly, a part of the reservoir has been transferred onto the paper The color of the deposit transferred to the paper is then measured with a MINOLTA CR300 colorimeter, the color being characterized by the colorimetric parameters L *, a * and b * The colorimetric parameters L * 0, a * 0 and b * 0 of the color of the color are determined. bare paper used [0026] The color difference E1 is then determined between the color of the transferred deposit and the color of the bare paper by the following ratio.

[0027] On the other hand, a total transfer reference is prepared by applying the composition directly on a paper identical to that previously used, at room temperature (25 ° C), extending the composition with a brush and to obtain a deposit of the composition of approximately 15 m, and then allowed to dry for 30 minutes at room temperature (25 ° C). After drying, the colorimetric parameters L * ’, a *’ and b * ’of the color of the deposit placed on the paper, corresponding to the total transfer reference color, are measured directly. The colorimetric parameters L * ’0, a *’ 0 and b * ’0 of the bare paper color used are determined. [0028] The color difference E2 is then determined between the total transfer reference color and the bare paper color by the following relationship.

[0030] The measurement is carried out on 4 supports successively and the transfer value corresponds to the average of the 4 measurements obtained with the 4 supports. The transfer rate is equal to the average of these four measures. [0031] The invention also relates to a skin and / or lip and / or phane make-up method consisting in applying the composition as defined above to the skin and / or lips and / or the lips. [0032] The composition according to the invention can be applied to the skin of both the face and the scalp and the body, the mucous membranes and the lips, the inside of the lower eyelids and the faneras such as eyelashes, hair, eyebrows and even the hairs. [0033] The invention also relates to the use of a polymer sequenced in an amount sufficient in a cosmetic composition to impart gloss and absence of transfer to a deposit of said composition.

[0035] The composition advantageously contains a smaller proportion of oils traditionally used to impart shine, whose oils are generally sticky. The composition according to the invention advantageously contains less than 30%, less than 25%, less than 20% and better less than 15% of at least one bright oil. [0036] By "oil" is meant a compound not miscible with water in any proportion, liquid at room temperature (25 ° C) and atmospheric pressure (760 mm Hg).

Sequenced polymer: [0039] The composition according to the present invention with

It has at least one sequenced polymer. By "sequenced" polymer, a polymer is understood as comprising at least two different sequences, preferably at least three different sequences. [0040] According to one embodiment, the sequenced polymer of the composition according to the invention is an ethylenic polymer. By "ethylenic" polymer, is meant a polymer obtained by polymerization of monomers having an ethylenic unsaturation. [0041] According to one embodiment, the sequenced polymer of the composition according to the invention is a linear polymer. In contrast, a polymer of non-linear structure is, for example, a polymer of branched, star, grafted or other structure. [0042] According to one embodiment, the sequenced polymer of the composition according to the invention is a film forming polymer. By "film-forming" polymer, is meant a polymer capable of forming, on its own or in the presence of an auxiliary film-forming agent, a continuous and adherent film on a support, especially on keratin materials. [0043] According to one embodiment, the sequenced polymer of the composition according to the invention is a non-elastomeric polymer. [0044] By "non-elastomeric polymer", a polymer is understood which, when subjected to a tension intended to stretch it (for example 30% in relation to its initial length), does not recover a length substantially identical to its length initial when the voltage ceases. [0045] More specifically, by "non-elastomeric polymer" is meant a polymer that has an instantaneous recovery Ri <50% and a delayed recovery R2h <70% after having suffered an elongation of 30%. Preferably, Ri is <30% and R2h <50%. [0046] More precisely, the non-elastomeric character of the polymer is determined according to the following protocol:

A polymer film is prepared by pouring a solution of the polymer into a Teflon matrix and then drying for 7 days in a controlled environment at 23  5 ° C and 50  10% relative humidity. A film of approximately 100 µm thick is then obtained in which rectangular test pieces (for example with the punch) of a width of 15 mm and a length of 80 mm are cut.

[0047] A tensile stress is imposed on this sample with an apparatus sold under the Zwick reference, under the same temperature and humidity conditions as for drying.

The test pieces are stretched at a speed of 50 mm / min. and the distance between the jaws is 50 mm, which corresponds to the initial length (10) of the test piece. [0048] Instant recovery Ri is determined as follows:

-

the test piece is stretched by 30% (max), that is, approximately 0.3 times its initial length (10);

-

the tension is relaxed by imposing a return speed equal to the traction speed, that is, 50 mm / min., and the residual elongation of the test piece is measured in percentage, after returning to zero tension (i). [ 0049] The instantaneous recovery in% (Ri) is given by the following formula:

Ri = ((max - i) / max) x 100 [0050] To determine the delayed recovery, the residual elongation of the test piece is measured in percentage (2h) 2 hours after returning to the voltage void [0051] Delayed recovery in% (R2h) is given by the following formula:

R2h = ((max - 2h) / max) x 100 [0052] For purely indicative purposes, a polymer sequenced according to an embodiment of the invention has an instantaneous recovery Ri of 10% and a delayed recovery R2h of 30% [0053] According to another embodiment, the sequenced polymer of the composition according to the invention does not contain a styrene unit. By polymer free of styrene unit, is meant a polymer containing less than 10%, preferably less than 5%, preferably less than 2%, preferably even less than 1%, by weight i) of styrene unit of formula -CH (C6H5) CH2- or ii) of substituted styrene unit, such as, for example, methylstyrene, chlorostyrene or chloromethylstyrene. [0054] According to one embodiment, the sequenced polymer of the composition according to the invention is derived from aliphatic ethylenic monomers. By aliphatic monomer, is meant a monomer that does not contain any aromatic groups. [0055] According to one embodiment, the sequenced polymer is an ethylene polymer derived from aliphatic ethylenic monomers having a carbon-carbon double bond and at least one ester group -COO- or amide -CON-. The ester group can be attached to one of the two unsaturated carbons by the carbon atom or the oxygen atom. The amide group can be attached to one of the two unsaturated carbons by the carbon atom or the nitrogen atom. [0056] According to one embodiment, the sequenced polymer comprises at least a first sequence and at least a second sequence.

By "at least" one sequence, one or more sequences are understood.

It is specified that in the foregoing and in what follows the terms "first" and "second" sequences do not in any way condition the order of said sequences (or blocks) in the polymer structure. [0057] According to one embodiment, the sequenced polymer comprises at least a first sequence and at least a second sequence having different glass transition temperatures (Tg).

In this embodiment, the first and second sequences can be linked together by an intermediate segment having a glass transition temperature comprised between the glass transition temperatures of the first and second sequences. [0058] According to one embodiment, the sequenced polymer comprises at least a first sequence and at least a second sequence joined together by an intermediate segment that includes at least one constituent monomer of the first sequence and at least one constituent monomer of the second sequence.

Preferably, the intermediate sequence is essentially derived from monomers constituting the first sequence and the second sequence.

By "essentially" is meant at least 85%, preferably at least 90%, better at 95% and even better at 100%. [0059] According to one embodiment, the sequenced polymer comprises at least a first sequence and at least a second sequence incompatible in the organic liquid medium of the composition of the invention.

By "sequences incompatible with each other", it is understood that the mixture formed by the polymer corresponding to the first sequence and by the polymer corresponding to the second sequence is not miscible in the majority liquid by weight contained in the organic liquid medium of the composition, at room temperature (25ºC) and atmospheric pressure (105 Pa), for a content in the polymer mixture greater than or equal to 5% by weight with respect to the total weight of the mixture (polymers and majority organic liquid), it being understood that:

i) said polymers are present in the mixture in a content such that the respective weight ratio ranges from 10/90 to 90/10, and that

ii) each of the polymers corresponding to the first and second sequences has a mean molecular mass (weight or numerical) equal to that of the sequenced polymer +/- 15%. [0060] If the organic liquid medium consists of a mixture of organic liquids, in the hypothesis of two or more liquids present in identical mass proportions, said polymer mixture is not miscible in at least one of them. [0061] If the organic liquid medium consists of a single organic liquid, the latter is very obviously the majority liquid by weight. [0062] By "organic liquid medium" is meant a medium that contains at least one organic liquid, that is, at least one liquid organic compound at room temperature (25 ° C) and atmospheric pressure (105 Pa). According to one embodiment, the majority liquid of the organic liquid medium is a volatile or non-volatile oil (fatty body). Preferably, the organic liquid is cosmetically acceptable (acceptable tolerance, toxicology and touch). The organic liquid medium is cosmetically acceptable, in the sense that it is compatible with keratin materials, such as oils or organic solvents commonly used in cosmetic compositions. [0063] According to one embodiment, the major liquid of the organic liquid medium is the solvent or one of the polymerization solvents of the sequenced polymer, as described below.

By polymerization solvent, is meant a solvent or a mixture of solvents. The polymerization solvent can be especially selected from ethyl acetate, butyl acetate, alcohols such as isopropanol or ethanol, aliphatic alkanes such as isododecane and mixtures thereof. Preferably, the polymerization solvent is a mixture of butyl acetate and isopropanol or isododecane. [0064] In general, the sequenced polymer can be incorporated into the composition in a high dry matter content, typically greater than 10%, greater than 20% and preferably still greater than 30%, and preferably even greater than 45%, by weight with respect to to the total weight of the composition, being nevertheless easy to formulate. [0065] Preferably, the sequenced polymer does not contain silicon atoms in its skeleton. By "skeleton", the main polymer chain is understood, as opposed to the pending side chains. [0066] Preferably, the polymer according to the invention is not water soluble, that is, that the polymer is not soluble in water or in a mixture of water and linear or branched lower monoalcohols of 2 to 5 carbon atoms, such as ethanol, isopropanol or n-propanol, without pH modification, at an active matter content of at least 1% by weight and at room temperature (25 ° C). [0067] Advantageously, the sequenced polymer used in the compositions according to the invention has a polydispersity index I of 2.8 to 6. [0068] The polydispersity index I of the polymer is equal to the ratio of the weight average mass Mw with respect to the number average mass Mn. [0069] The weight average (Mw) and numerical (Mn) mean molar masses are determined by liquid permeation gel chromatography (THF solvent, calibration curve established with linear polystyrene standards, refractometric detector). [0070] The weight average mass (Mw) of the sequenced polymer is preferably less than or equal to 300,000; goes, for example, from 35,000 to 200,000 and better than 45,000 to

150,000 [0071] The number average mass (Mn) of the sequenced polymer is preferably less than or equal to 70,000; goes, for example, from 10,000 to 60,000 and better from 12,000 to 50,000. [0072] Each sequence or block of the polymer sequence- Do it comes from one type of monomer or several types of different monomers.

This means that each sequence can be constituted by a homopolymer or by a copolymer, this copolymer which constitutes the sequence can be in turn statistical or alternated. [0073] The indicated glass transition temperatures of the first and second sequences may be theoretical Tg determined from the theoretical Tg of the constituent monomers of each of the sequences, which can be found in a reference manual such as the Polymer Handbook, 3rd ed., 1989, John Wiley, according to the following relationship, called Fox's Law:

where mási is the mass fraction of monomer i in the sequence considered and Tgi is the glass transition temperature of homopolymer of monomer i. [0074] Unless otherwise indicated, the Tg indicated for the first and second sequences in the present application are theoretical Tg. [0075] The difference between the glass transition temperatures of the first and second sequences is generally greater than 10 ° C, preferably greater than 20 ° C and better than 30 ° C. [0076] It is intended to designate in the present invention by the expression:

"Between ... and ...", a range of values where the mentioned limits are excluded, and

"From ... to ..." and "from ... to ...", a range of values where limits are included. a) Sequence having a Tg greater than or equal to 40 ° C [0077] The sequence having a Tg greater than or equal to 40 ° C has, for example, a Tg of 40 to 150 ° C, preferably greater than or equal to 50 ° C, for example 50 ° C to 120ºC and better than or equal to 60ºC, for example from 60ºC to 120ºC. [0078] The sequence having a Tg greater than or equal to 40 ° C may be a homopolymer or a copolymer. [0079] The sequence having a Tg greater than or equal to 40 ° C can proceed in all or part of one or more monomers such that the homopolymer prepared from these monomers has a glass transition temperature greater than or equal to 40 ° C. [0080] If this sequence is a homopolymer, it is derived from monomers such that the homopolymers prepared from these monomers have glass transition temperatures greater than or equal to 40 ° C. This first sequence may be a homopolymer, consisting of a single type of monomer (where the Tg of the corresponding homopolymer is greater than or equal to 40 ° C). [0081] In the event that the first sequence is a copolymer, it may proceed in whole or in part from one or more monomers whose nature and concentration are selected such that the Tg of the resulting copolymer is greater than or equal to 40 ° C. The copolymer may for example include:

-

monomers such that homopolymers prepared from these monomers have Tg greater than or equal to 40 ° C, for example a Tg of 40 to 150 ° C, preferably greater than or equal to 50 ° C, for example 50 ° C to 120 ° C, and better than or equal to 60 ° C, for example from 60 ° C to 120 ° C, and

[0087] If this sequence is a homopolymer, it is derived from monomers such that the homopolymers prepared from these monomers have glass transition temperatures of less than or equal to 20 ° C. This second sequence may be a homopolymer, consisting of a single type of monomer (where the Tg of the corresponding homopolymer is less than or equal to 20 ° C). [0088] In the event that the sequence having a Tg of less than or equal to 20 ° C is a copolymer, it may proceed in whole or in part from one or more monomers, the nature and concentration of which are selected so that the Tg of the resulting copolymer is lower or equal to 20 ° C.

[0095] If this sequence is a homopolymer, it is derived from monomers (or major monomers) such that the homopolymers prepared from these monomers have glass transition temperatures between 20 and 40 ° C. This first sequence may be a homopolymer, consisting of a single type of monomer (where the Tg of the corresponding homopolymer ranges from 20 ° C to 40 ° C).

[0147] As solvents usable in the composition of the invention, apart from the above-mentioned hydrophilic organic solvents, liquid ketones at room temperature, such as methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone, isophorone, cyclohexanone and acetone, may be cited; liquid propylene glycol ethers at room temperature, such as propylene glycol monomethyl ether, propylene glycol monomethyl ether acetate and dipropylene glycol mono-n-butyl ether; short chain esters (from 3 to 8 carbon atoms in total), such as ethyl acetate, methyl acetate, propyl acetate, n-butyl acetate and isopentyl acetate; liquid ethers at room temperature, such as diethyl ether, dimethyl ether or dichlorodyethyl ether; liquid alkanes at room temperature, such as decane, heptane, dodecane, isododecane and cyclohexane; liquid aromatic cyclic compounds at room temperature, such as toluene and xylene; liquid aldehydes at room temperature, such as benzaldehyde and acetaldehyde; and mixtures thereof. [0148] The composition may include, apart from the sequenced polymer described above, an additional polymer, such as a film forming polymer. According to the present invention, "film-forming polymer" is understood as a polymer capable of forming, on its own or in the presence of an auxiliary film-forming agent, a continuous and adherent film on a support, especially on keratin materials.

Among the film-forming polymers that can be used in the composition of the present invention, synthetic polymers, radical or poly-condensed type, naturally occurring polymers and mixtures thereof may be mentioned. As the film-forming polymer, there may be mentioned, in particular, acrylic polymers, polyurethanes, polyesters, polyamides, polyureas and cellulosic polymers, such as nitrocellulose.

The polymer can be associated with one or more auxiliary film-forming agents. Such a film-forming agent can be selected from all the compounds known to those skilled in the art as capable of fulfilling the function sought, and especially between the plasticizing agents and the coalescing agents. [0149] The composition according to the invention may include at least one wax. Wax within the meaning of the present invention means a lipophilic compound, solid at room temperature (25 ° C), with reversible solid / liquid state change, which has a melting point greater than or equal to 30 ° C, which can go up to 120 ° C .

The melting point of the wax can be measured with a differential scanning calorimeter (D.S.C.), for example the calorimeter sold under the designation DSC 30 by METLER.

The waxes can be hydrocarbon, fluorinated and / or silicone and be of vegetable, mineral, animal and / or synthetic origin. In particular, the waxes have a melting temperature greater than 25 ° C and better than 45 ° C.

[0150] The nature and quantity of solid fatty bodies are a function of the mechanical properties and textures sought. By way of indication, the composition may contain from 0 to 50% by weight of waxes with respect to the total weight of the composition, and better from 1 to 30% by weight. [0151] The composition according to the invention may also include one or more dye materials selected from water-soluble dyes and powdery dyes, such as pigments, mother of pearl and sequins well known to those skilled in the art. The coloring materials may be present in the composition in a content of 0.01% to 50% by weight with respect to the weight of the composition, preferably 0.01% to 30% by weight. [0152] By pigments, it is necessary to understand particles of any shape, white or colored, mineral or organic, insoluble in the physiological environment, intended to give color to the composition.

By mother of pearl, it is necessary to understand iridescent particles of any form, especially produced by some mollusks in their shell or synthesized. [0153] The pigments can be white or colored, mineral and / or organic. It is possible to mention, among the mineral pigments, titanium dioxide, possibly surface treated, zirconium or cerium oxides, as well as zinc, iron (black, yellow or red) or chromium oxides, the violet of manganese, ultramarine blue, chromium hydrate and ferric blue and metallic powders, such as aluminum powder or copper powder.

[0155] Pearlescent pigments can be selected from white pearly pigments, such as titanium coated mica or bismuth oxychloride, pearly colored pigments, such as titanium mica coated with iron oxides, specially coated titanium mica with ferric blue or with chromium oxide and titanium mica coated with an organic pigment of the aforementioned type, as well as pearly pigments based on bismuth oxychloride. Interferential pigments can also be used, especially with liquid or multilayer crystals. [0156] Water-soluble dyes are, for example, beet juice and methylene blue. [0157] The composition according to the invention may further include one or more fillers, especially in a content of 0.01% to 50% by weight with respect to the total weight of the composition, preferably 0.01% to 30% by weight. By charges, particles of any form, colorless or white, mineral or synthetic, insoluble in the medium of the composition must be understood regardless of the temperature at which the composition is manufactured. These charges are especially useful for modifying the rheology or texture of the composition.

The charges can be mineral or organic and in any way, platelet, spherical or oblong, whatever the crystallographic form (for example laminar, cubic, hexagonal, orthorhombic, etc.). It is possible to mention talcum, mica, silica, kaolin, polyamide (Nylon®) powders (Orgasol®, from the Atochem house), poly-alanine and polyethylene, tetrafluoroethylene (Teflon) polymer powders ®), lauroillisin, starch, boron nitride, hollow polymer microspheres, such as polyvinylidene / acrylonitrile chloride, such as Expancel® (Nobel Industrie) or acrylic acid copolymers (Polytrap®, from society) Dow Corning) and silicone resin microbeads (Tospearls® from Toshiba, for example), elastomeric polyorganosiloxane particles, precipitated calcium carbonate, magnesium carbonate and hydrocarbonate, hydroxyapatite, hollow silica microspheres (Silica Beads®, from Maprecos), glass or ceramic microcapsules and metal soaps derived from organic carboxylic acids of 8 to 22 carbon atoms, preferably 12 to 18 carbon atoms, for example, estea time of zinc, magnesium or lithium, zinc laurate and magnesium myristate. [0158] The composition according to the invention can be especially in the form of a rod, suspension, dispersion, solution, gel, emulsion, especially oil-in-water emulsion (Ac / Ag) or water-in-oil ( Ag / Ac) or multiple (Ag / Ac / Ag or polyol / Ac / Ag or Ac / Ag / Ac), cream, paste, foam, vesicle dispersion, especially ionic lipids or not, biphasic lotion or multiphasic, of spray, of powder or of paste, especially of flexible paste (especially of paste with a dynamic viscosity at 25 ° C of the order of 0.1 to 40 Pa.s under a shear rate of 200 s-1, after 10 minutes of measurement in conical / flat geometry). The composition can be anhydrous; for example, it may be an anhydrous paste. [0159] The person skilled in the art may select the appropriate galenic form, as well as its method of preparation, based on their general knowledge, taking into account, on the one hand, the nature of the constituents used, especially their solubility in the support, and by other the application contemplated for the composition. [0160] The composition according to the invention can be a make-up composition, such as complexion products (make-up bases), blushes or eye shadows, lipstick bars, concealer products, blushers, mascaras , eye profilers, eyebrow makeup products, lip or eye pencils, nail products, such as nail polishes, body makeup products and hair makeup products (mask or hairspray).

The composition according to the invention can also be a skin and body care product, especially a sunscreen or skin coloring product (such as a self tanner). [0161] The composition according to the invention can also be a hair product, especially for the maintenance of styling or hair modeling. The hair compositions are preferably shampoos, gels, marking lotions, hand drying lotions and styling and styling compositions, such as lacquers or sprays. [0162] The present invention also has as its object a cosmetic set consisting of:

- a container that delimits at least one compartment, said container being closed by a closing element, and

- a composition as described above arranged inside said compartment. [0163] The container can have any suitable shape. It can be especially shaped like a bottle, tube, canister, case, box, envelope or case. [0164] The closure element may be in the form of a removable cap, a lid, an operculum, a tear strip or a capsule, especially of the type that carries a body attached to the container and an articulated cap on the body. It may also be in the form of an element that ensures selective closure of the container, especially a pump, a valve or a flip lid. [0165] The container may be associated with an applicator, especially in the form of a brush that carries an arrangement of hairs maintained by a braided thread. Such braided brush is especially described in US Pat. 4,887,622. It can also be in the form of a comb that carries a plurality of application elements, especially obtained by molding. Such combs are described, for example, in FR 2,796,529. The applicator may be in the form of a brush, as described, for example, in FR 2,722,380. The applicator may be in the form of a foam or elastomer block, a marker or a spatula. The applicator may be free (tassel or sponge) or integral with a rod carried by the closure element, as described, for example, in US Pat. 5,492,426. The applicator may be integral with the container, as described, for example, in patent FR 2,761,959. [0166] The product can be contained directly in the container or indirectly. By way of example, the product may be arranged on an impregnated support, especially in the form of a wipe or a buffer, and disposed (as a unit or as a plurality) in a box

or in an envelope. Such support incorporating the product is described, for example, in the application WO 01/03538. [0167] The closure element may be coupled to the container by screwing. Alternatively, the coupling between the closure element and the container is carried out other than by screwing, especially by a bayonet mechanism, by ratchet, pressure, welding or gluing or by magnetic attraction. By "ratchet", it is understood, in particular, any system that involves the passage of a weatherstrip or a cord of material by elastic deformation of a portion, especially of the closure element, and then by return to the position of non-tension elastically of said portion after the passage of the weatherstrip or cord.

[0168] The container may be at least partly made of thermoplastic material. By way of examples of thermoplastic materials, polypropylene can be cited

or polyethylene.

Alternatively, the container is made of non-thermoplastic material, especially glass or metal (or alloy). [0169] The container can be rigid walls or deformable walls, especially in the form of a tube or a tube jar. [0170] The container may include means intended to cause or facilitate the distribution of the composition. By way of example, the container can be of deformable walls to cause the composition to exit in response to an overpressure inside the container, whose overpressure is caused by elastic (or non-elastic) crushing of the walls of the container. Alternatively, especially when the product is in the form of a bar, the latter can be dragged by a piston mechanism. Always in the case of a bar, especially a makeup product (lipstick, makeup base, etc.), the container can carry a mechanism, especially a rack, or with a threaded rod, or with a helical ramp, suitable to move a bar in the direction of said opening. Such a mechanism is described, for example, in FR 2,806,273 or in FR

2,775,566. Such a mechanism for a liquid product is described in FR 2,727,609. [0171] The container may consist of a briefcase with a bottom that delimits at least one housing containing the composition and a lid, especially articulated on the bottom and suitable for covering at least part of said bottom. Such a briefcase is described, for example, in application WO 03/018423 or in patent FR 2,791,042. [0172] The container may be equipped with a drainer arranged in proximity to the opening of the container. Such a drainer allows the applicator to dry and possibly the rod of which it can be integral. Such a drainer is described, for example, in patent FR 2,792,618. [0173] The composition may be at atmospheric pressure inside the vessel (at room temperature) or pressurized, especially by means of a propellant gas (aerosol). In the latter case, the container is equipped with a valve (of the type used for aerosols). [0174] The content of the aforementioned patents or patent applications is incorporated by reference in the present application. [0175] The following examples illustrate in a non-limiting manner the compositions according to the invention.
