Description

[0001] The object of the present invention is a cosmetic composition containing a particular sequenced polymer and a plasticizer, intended to be applied to the keratinous materials of human beings, such as skin, lips, eyelashes, eyebrows, nails or hair. The composition is more particularly intended to be applied to the skin or lips.

[0002] The composition according to the invention may be a make-up composition or a composition for the care of keratin materials, especially skin and lips, and preferably a makeup composition.

[0003] The makeup composition may be a lip makeup product (lipstick), a makeup base, an eye shadow, a blusher, a dark circles corrective product, an eye profiler, a product of body makeup, a mascara, a nail polish or a hair makeup product. twenty

[0004] The care composition may be a product for the care of the skin of the body and the face, especially a solar product, or a skin coloring product (such as a self tanner). The composition can also be a hair product, especially for the maintenance of styling or hair modeling.

[0005] The lipstick and makeup base compositions are usually used to provide an aesthetic color to the lips or skin, especially to the face. These makeup products generally contain fatty phases, such as waxes and oils, pigments and / or fillers, and possibly additives, as cosmetic or dermatological active ingredients.

[0006] These compositions, when applied over 35

the skin has the inconvenience of transferring, that is, of depositing at least in part, leaving traces, on certain supports with which they can make contact, and especially a glass, a cup, a cigarette, a garment or skin . This results in a mediocre persistence of the applied film, which needs a regular renewal of the application of the makeup base composition or lipstick. On the other hand, the appearance of these unacceptable traces especially on the neck of the blouses can separate some 10 women from the use of this type of makeup.

[0007] Thus, makeup compositions of keratin materials, especially of the lips and skin, are advantageously "without transfer", which have the advantage of forming a deposit of good persistence, especially that they are not sought. deposit, at least in part, on the supports with which they come in contact (va-so, clothes, cigarettes, tissues).

[0008] To improve the persistence of makeup products, the use of film-forming polymers is known. For example, US-6074654 and WO02 / 067877 propose using silicone resins. But the introduction of these film-forming polymers can result in films that are too hard, which then tend to crack over time. In particular, these hard films do not correctly follow the movement of the skin or lips and therefore have a bad persistence on the skin or the lips, the film disintegrating rapidly.

 On the other hand, a film that is too hard 30 deposited on the lips or skin will cause a sensation of tightness, making the deposit uncomfortable for the user.

[0009] The present invention is therefore intended to provide a cosmetic composition capable of forming

a flexible film, especially capable of following the movements of the lips or skin.

[0010] US Pat. 6,513,206 describes cosmetic compositions, and especially lip carmines, containing linear ethylene copolymers prepared by GTP (Group Transfer Polymerisation) in association with triisoestearyl citrate. Patent GB 1,324,745 relates to water-in-oil or oil-in-water emulsion type makeup compositions containing emulsifying bi-or trisequenced block copolymers, or also statistical polymers, and contemplates their association with diisopropyl adipate, which allows better hydration of the skin. Patent application WO 00/26285 describes gel-shaped compositions that contain a linear, graft, star or radial tribloque polymer, star or graft, in association with an ester. Application FR-A-2,798,061 describes a cosmetic composition containing a dispersion of surface stabilized polymer particles by a sequenced copolymer. twenty

[0011] The object of the invention is also to provide a cosmetic composition that forms a deposit on the keratinous materials, in particular on the skin or lips, comfortable during the course of time. 25

[0012] The inventors have discovered that it is possible to obtain such a composition using a particular sequenced polymer associated with a particular plasticizer.

[0013] More precisely, the present invention therefore has as its object a cosmetic composition, especially for the make-up or care of keratin materials, in particular the skin or lips, which contains a Cosmetically acceptable organic liquid medium, a sequenced polymer and a plasticizer, characterized by: 35

 - the sequenced polymer being a film-forming linear ethylenic polymer containing first and second sequences joined together by an intermediate segment, which is a statistical polymer that includes at least one constituent monomer of the first sequence and at least 5 a constituent monomer of the second sequence,

 - be the plasticizer as described 20 below.

[0014] Advantageously, the sequenced polymer is free of styrene.

[0015] Advantageously still, the sequenced polymer is non-elastomeric. 25

[0016] Preferably also, the first and second sequences are incompatible with each other.

[0017] The composition according to the invention makes it possible to obtain a deposit, especially a make-up deposit, on keratinous materials, especially on the skin or lips, which has a good gloss and good transfer-free properties.

[0018] The composition according to the invention also makes it possible to obtain a deposit on the keratinic materials, especially on the skin or lips, that

There is no feeling of resection or tightness: the deposit thus obtained is thus comfortable in the course of time for the user.

[0019] The object of the invention is also a method of making keratin materials, especially of the skin or lips, consisting of the application on keratin materials, especially on the skin or lips, of a composition as defined above.

[0020] The object of the invention is also the use of a composition as defined above to obtain a deposit, especially a make-up, on keratinous materials, in particular on the skin or lips, flexible and / or comfortable in the course of time. fifteen

[0021] By means of a cosmetically acceptable organic liquid medium, means means that includes at least one liquid organic compound at room temperature (25 ° C) and atmospheric pressure (105 Pa) compatible with keratin materials, especially the skin and lips, 20 such as oils or organic solvents commonly used in cosmetic compositions. The sequenced polymer of the composition according to the invention is a film-forming linear sequenced ethylenic polymer.

[0022] By "ethylenic" polymer, a polymer obtained by polymerization of monomers having an ethylenic unsaturation is understood.

[0023] By "sequenced" polymer, a polymer is understood as comprising at least 2 different sequences, preferably at least 3 different sequences. 30

[0024] The polymer is a polymer of linear structure. In contrast, a polymer of non-linear structure is, for example, a polymer of branched, star, grafted or other structure. By polymer "filmóge-no", is meant a polymer capable of forming, by itself so-35

it or in the presence of an auxiliary film-forming agent, a continuous and adherent film on a support, especially on keratin materials.

[0025] 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 organic liquid majority by weight of the organic liquid medium of the composition, at room temperature (25 ° C) and atmospheric pressure (105 Pa), for a content of the polymer mixture greater than or equal to 5% by weight with respect to the total weight of the mixture (polymers and solves -te), understanding 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%. twenty

[0026] In the event that the organic liquid medium includes a mixture of organic liquids, and in the hypothesis of two or more organic liquids present in identical mass proportions, said polymer mixture is not miscible in at least one of they. 25

[0027] Of course, in case the organic liquid medium includes a single organic liquid, the latter is the majority organic liquid.

[0028] Advantageously, the major organic liquid of the composition is the organic polymerization solvent of the sequenced polymer or the major organic solvent of the mixture of organic solvents for polymerization of the sequenced polymer.

[0029] The intermediate sequence is a sequence that includes at least one constituent monomer of the first 35

sequence and at least one constituent monomer of the second sequence of the polymer and allows to "reconcile" these sequences.

[0030] Preferably, the polymer used in the composition according to the invention does not contain silicon si-5 atoms in its skeleton. By "skeleton", the main polymer chain is understood, as opposed to the pending side chains.

[0035] More specifically, 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 te-floated matrix and then drying for 7 days in a controlled environment at 23  5 ° C and 50  35

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 5 mm and a length of 80 mm are traced.

[0036] A tensile solicitation is imposed on this sample with the aid of an apparatus marketed under the Zwick reference, under the same temperature and humidity conditions as for drying. The test pieces 10 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 piece.

[0037] The instantaneous 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, 20 50 mm / min., and the residual elongation of the test piece is measured in percentage after returning to zero voltage (i).

[0038] Instant recovery in% (Ri) is given by the following formula:

Ri = ((max - i) / max) x 100

[0039] To determine the delayed recovery, the residual elongation of the test piece is measured in percentage (2h).

[0040] Delayed recovery in% (R2h) is given by the following formula:

R2h = ((max - 2h) / max) x 100

[0041] For purely indicative purposes, a polymer used according to an embodiment of the invention has an instantaneous recovery of Ri of 10% and a recovery.

 Of course, the person skilled in the art will take care to select this or these possible complementary compounds and / or their amount in such a way that the advantageous properties of the corresponding composition according to the invention are not altered, or are not substantial. - Particularly, by the contemplated addition. 35

[0182] The composition according to the invention can be specially prepared in the form of a suspension, dispersion, solution, gel, emulsion, especially oil-in-water (Ac / Ag) or water- emulsion. in-oil (Ag / Ac) or multiple (Ag / Ac / Ag or polyol / Ac / Ag or Ac / Ag / Ac), 5 cream, paste, foam, vesicle dispersion, especially lipids ionic or not, biphasic or multiphasic lotion, spray, powder or paste, especially flexible paste (especially paste with a dynamic viscosity at 25 ° C of the order of 0.1 to 40 10 Pa.s under a shear rate 200 s-1 after 10 minutes of measurement in conic / flat geometry). The composition can be anhydrous; for example, it can be a bar or an anhydrous paste. The composition can be a composition without rinsing. fifteen

[0183] 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 on the other the application contemplated for the composition.

[0184] According to another aspect, the invention also relates to a cosmetic set consisting of:

 i) a container that delimits at least one compartment, said container being closed by a closure element, and

 ii) a composition disposed within said compartment, keeping the composition in accordance with the invention. 30

[0185] The container may have any suitable shape. It can be especially shaped like a bottle, tube, canister, case, box, envelope or Mandin.

[0186] The closure element may be in the form of 35

a removable cap, a cover, an operculum, a tear strip or a capsule, especially of the type that has 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 the selective closure of the container, especially a pump, a valve or a flip cover.

[0187] 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 a braided brush is especially described in US Pat. 4,887,622. It may 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 20 to 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.

[0188] The product may 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.

[0189] The closure element may be coupled to the container by screwing. Alternatively, the coupling between the closure element and the container is

Performs otherwise than by screwing, especially by a bayonet mechanism, by ratchet, pressure, welding or gluing or by magnetic attraction. By "ratchet" 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 elastic tension of said portion after the passage of the weatherstrip or the cord.

[0190] The container may be at least in part 10 made of thermoplastic material. By way of examples of thermoplastic materials, there may be mentioned polypropylene or polyethylene.

 Alternatively, the container is made of non-thermoplastic material, especially glass 15 or metal (or alloy).

[0191] The container may be of rigid walls or deformable walls, especially in the form of a tube or a tube vial.

[0192] The container may include means intended to cause or facilitate the distribution of the composition. By way of example, the container can be de-formable 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 make-up product (lipstick, make-up base, etc.), the container can carry a mechanism, especially with a zipper, or with a threaded rod, or with a helical ramp, suitable for moving a bar in the direction of said opening. Such mechanism is described, for example, in FR 2,806,273 35

or in patent FR 2,775,566. Such a mechanism for a liquid product is described in FR 2,727,609.

[0193] The container may be constituted by 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 at least partially covering said bottom. Such a briefcase is described, for example, in the application WO 03/018423 or in the patent FR 2,791,042.

[0194] The container may be equipped with an es-10 curlator 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 runner is described, for example, in FR 2,792,618. fifteen

[0195] 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 of 20 used for aerosols).

[0196] The content of the aforementioned patents or patent applications is incorporated by reference in the present application.

[0197] The invention is illustrated in greater detail by the examples described below.

Example 1:

Preparation of a poly (isobornyl acrylate / isobornyl methacrylate / 2-ethylhexyl acrylate) polymer

[0198] 100 g of isododecane are introduced into a 1-liter re-30 actor and then the temperature is increased to move from room temperature (25 ° C) to 90 ° C in 1 hour.

[0199] Then, at 90 ° C and within 1 hour, 105 g of isobornyl acrylate, 105 g of iso-bornyl methacrylate, 110 g of isododecane and 1.8 g of 2,5-bis (2-ethyl-) are added 35

hexanoylperoxy) -2,5-dimethylhexane (Trigonox® 141 from Akzo Nobel).

 The mixture is maintained for 1 h 30 at 90 ° C.

 Then, 90 g of 2-5 ethylhexyl acrylate, 90 g of isododecane and 1.2 g of 2,5-bis (2-ethylhexanoylperoxy) -2.5 are introduced into the previous mixture, at 90 ° C and in 30 minutes -dimethylhexane.

 The mixture is kept 3 hours at 90 ° C and then the whole is cooled.

 A 50% solution in the active matter of polymer in isododecane is obtained.

[0200] A polymer is obtained comprising a first sequence or block of poly (isobornyl acrylate / isobornyl methacrylate) having a Tg of 110 ° C, a second sequence of 2-ethylhexyl polyacrylate having a Tg of -70 ° C and an intermediate sequence which is a statistical polymer of isobornyl acrylate / isobornyl methacrylate / 2-ethylhexyl acrylate.

[0201] This polymer has a weight average mass of 103,900 and a number average mass of 21,300, or 20, a polydispersity index I of 4.89.

[0203] Octyldodecanol, sili-conado oil, Parleam oil, sucrose acetate isobutyrate and polyvinylpyrrolidone / eicosenne 5 copolymer are mixed by heating at approximately 60 ° C. With this mixture, a pigmentary crushing of the pigments is carried out by effecting 3 passes of the mixture through the three-cylinder crusher.

[0204] Then the pigmentary crushing, the isododecane and the polymer are mixed at room temperature and the silica is then introduced at the end. The formula is then introduced into a sealed kettle.

[0205] The lip carmine forms a film that has a hardness of 20 seconds, measured with the 15 Persoz pendulum according to the protocol described above.

[0206] This lip carmine allows, therefore, to obtain a flexible make-up, comfortable to wear in time and which presents a good absence of transfer.

Example 3: 20

[0207] A lip carmine was prepared that did not contain plasticizer, and therefore was not part of the invention, which had the following composition:

Sequenced polymer of example 1 at 50%

by weight in isododecane 50 g 25

Pyrogenized treated hydrophobic silica

(Degussa R 972 spray) 5 g
