Title: OILY DISPERSION COMPRISING A POLYMERIC PARTICLE AND A STABILIZER BEARING A C9-C22 ALKYL GROUP AND A PLASTICIZER, AND PROCESS FOR TREATING KERATIN MATERIALS USING THE OILY DISPERSION
[0001] The present invention relates to an oily dispersion (A) comprising: at least one particle consisting of an ethylenic polymer i), at least one polymeric stabilizer comprising a (Cg-C22)alkyl group ii), at least one hydrocarbon-based fatty substance which is liquid at 20°C and 1 atmosphere iii), and at least one plasticizer iv). The invention also relates to a process for treating keratin materials, notably human keratin materials such as the skin, the hair or the eyelashes, involving the application to said materials of at least one oily dispersion (A); to a process for preparing the oily dispersion, and to a multi-compartment kit comprising ingredients i) to iv).
[0002] During the aging process, various signs appear on the skin which are very characteristic of this aging, reflected notably by a change in the skin structure and functions. The main clinical signs of skin aging are notably the appearance of fine lines and deep wrinkles, which increase with age.
[0003] It is known practice to treat these signs of aging using cosmetic or dermatological compositions containing active agents that are capable of combating aging, such as a- hydroxy acids, p-hydroxy acids and retinoids. These active agents act on wrinkles by eliminating dead skin cells and by accelerating the cell renewal process. However, these active agents have the drawback of being effective for the treatment of wrinkles only after a certain application time. Now, it is increasingly sought to obtain an immediate effect of the active agents used, rapidly resulting in smoothing-out of wrinkles and fine lines and in the disappearance of fatigue marks.
[0004] Cosmetic products often require the use of a film-forming polymer to obtain a deposit of the product on keratin materials that has good cosmetic properties. In particular, it is necessary for the film-forming deposit to have good persistence, in particular for the deposit not to transfer during contact with the fingers or clothing, and also good resistance on contact with water, notably rain or during showering and for the deposit to be insensitive to perspiration or sebum, and also food fats, notably dietary fats such as oils.
[0005] It is known practice to use dispersions of polymer particles, in organic media such as hydrocarbon-based oils. Polymers are notably used as film-forming agents in makeup products such as mascaras, eyeliners, eyeshadows or lipsticks. EP 0 749 747 describes in the examples dispersions in hydrocarbon-based oils (liquid paraffin, isododecane) of
acrylic polymers stabilized with polystyrene/copoly(ethylene-propylene) diblock copolymers. The film obtained after application of the dispersion to the skin is sparingly glossy. FR 1 362 795 also describes the use of dispersions of surface-stabilized polymer particles containing hydrocarbon-based oils for making up the lips and the eyelashes. WO 2010/046 229 describes dispersions in isododecane of acrylic polymers stabilized with stabilizing polymers. FR 1 362 795 describes the use of dispersions of surface-stabilized polymer particles containing hydrocarbon-based oils for making up the lips and the eyelashes.
[0006] In the field of dyeing keratin fibers, it is already known practice to dye keratin fibers via various techniques using direct dyes for non-permanent dyeing, or dye precursors for permanent dyeing.
[0007] Non-permanent dyeing or direct dyeing consists in dyeing keratin fibers with dye compositions containing direct dyes. These dyes are colored and coloring molecules that have affinity for keratin fibers. They are applied to the keratin fibers for a time necessary to obtain the desired coloring, and are then rinsed out.
[0008] The standard dyes that are used are, in particular, dyes of the nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine or triarylmethane type, or natural dyes.
[0009] Some of these dyes may be used under lightening conditions, which enables the production of colorings that are visible on dark hair.
[0010] It is also known practice to dye keratin fibers permanently via oxidation dyeing. This dyeing technique consists in applying to the keratin fibers a composition containing dye precursors such as oxidation bases and couplers. Under the action of an oxidizing agent, these precursors form one or more colored substances in the hair.
[0011] The variety of molecules used as oxidation bases and couplers allows a wide range of colors to be obtained, and the colorings resulting therefrom are generally permanent, strong and resistant to external agents, notably to light, bad weather, washing, perspiration and rubbing.
[0012] In order to be visible on dark hair, these two dyeing techniques require prior or simultaneous bleaching of the keratin fibers. This bleaching step, performed with an oxidizing agent such as hydrogen peroxide or persalts, results in appreciable degradation of the keratin fibers, which impairs their cosmetic properties. The hair then has a tendency to become coarse, more difficult to disentangle and more brittle.
[0013] Another coloring method consists in using pigments. Specifically, the use of pigment on the surface of keratin fibers generally makes it possible to obtain colorings that are notably visible on dark hair, since the surface pigment masks the natural color of the fiber. The use of pigment for dyeing keratin fibers is described, for example, in patent application FR 2 741 530, which recommends using, for the temporary dyeing of keratin fibers, a composition comprising at least one dispersion of film-forming polymer particles comprising at least one acid function and at least one pigment dispersed in the continuous phase of said dispersion.
[0014] The colorings obtained via this dyeing method become removed from the very first shampoo wash.
[0015] It is moreover known from patent application FR 2 907 678 to perform colored coating of the hair using a composition comprising a polysiloxane/polyurea block copolymer and a pigment. However, with such a composition, the coating results obtained may occasionally lack homogeneity and the strand separation after combing is not always satisfactory.
[0016] FR 3 014 875 describes the use of a dispersion of C1-C4 alkyl (meth)acrylate polymer particles surface-stabilized with an isobornyl (meth)acrylate polymeric stabilizer in a non-aqueous medium containing an oil. The deposits obtained using this technology are not always satisfactory, notably in terms of resistance to sebum.
[0017] FR 3 029 786 is focused on makeup dispersions of polymer particles stabilized with at least one stabilizer which is a Cs alkyl (meth)acrylate homopolymer or a copolymer of Cs alkyl (2-ethylhexyl) (meth)acrylate and of C1-C4 alkyl (meth)acrylate. These dispersions are not always satisfactory in terms of resistance to fatty substances or sebum, which may be a curb on their use in lip makeup, for example. Furthermore, these dispersions may have a feel that is considered too “tacky” after application to the keratin materials, which may be prohibitive for certain applications such as lip or eyelash makeup, etc.
[0018] It is also known practice to use other polymer particles stabilized with C9-C22 alkyl (alkyl)acrylate polymers, notably for hair treatment (see FR 3 097 756).
[0019] Thus, the aim of the present invention is to provide a composition for treating keratin materials, in particular the skin, preferably human skin and more preferentially facial skin, the residual film of which after application to said keratin materials adheres well to the keratin materials, is elastic and shows the least possible fragmentation and the least possible detachment from the substrate, which is not tacky, has good persistence with
respect to external attacking factors, and over time, does not leach, is resistant to sweat and to sebum, and is relatively insensitive to oils such as dietary oils, notably to sebum. Moreover the keratin material after being treated with the composition of the invention is pleasant to the touch (soft, smooth and touch even), the color when the said composition comprises at least one dye and/or at least one pigment is homogeneous. The appearance keratin material after application on keratin is very aesthetic, from matte, satin to gloss, preferably gloss satin, more preferably gloss.
[0020] Another aim of the present invention is to provide a composition for treating keratin fibers, notably human keratin fibers such as the hair, the eyelashes or the eyebrows, the residual film of which after application to said fibers adheres well to the fibers, without any fragmentation/detachment from said fibers, which has good persistence with respect to attacking factors such as brushing, does not leach, is resistant to sweat, sebum, light and bad weather, and is persistent with respect to shampoo washing and to the various attacking factors to which said fibers may be subjected, notably to sebum, without degrading said fibers, and while keeping the keratin fibers perfectly individualized.
[0021] The technical problem has been solved by using an oily dispersion (A) for treating keratin materials, notably human keratin materials such as the hair, the eyelashes or the skin, in which the oily dispersion (A) is preferably anhydrous, and comprises: i) one or more particles including one or more polymers chosen from: a) ethylenic homopolymers of (Ci-C4)alkyl (Ci-C4)(alkyl)acrylate, preferably (Ci- C4)alkyl (meth)acrylate; b) ethylenic copolymers of b1) (Ci-C4)alkyl (Ci-C4)(alkyl)acrylate and of b2) ethylenic monomers comprising one or more carboxyl, anhydride, phosphoric acid, sulfonic acid and/or aryl groups such as benzyl; in particular, b2) is a (Ci-C4)(alkyl)acrylic acid such as (meth)acrylic acid, more particularly copolymers of (Ci-C4)alkyl (meth)acrylate and of (meth)acrylic acid; c) ethylenic copolymers of (Ci-C4)alkyl (Ci-C4)(alkyl)acrylate, preferably (Ci-C4)alkyl (meth)acrylate; and ii) one or more polymeric stabilizers chosen from: d) ethylenic homopolymers of (Cg-C22)alkyl (Ci-Ce)(alkyl)acrylate, preferably ethylenic homopolymers of (Cg-C22)alkyl (meth)acrylate; and e) ethylenic copolymers of e1) (Cg-C22)alkyl (Ci-Ce)(alkyl)acrylate, and of e2) (Ci- C4)alkyl (Ci-C4)(alkyl)acrylate; preferably, the copolymers e) are copolymers of (Cg- C22)alkyl (meth) acrylate and of (Ci-C4)alkyl (meth)acrylate; iii) one or more hydrocarbon-based liquid fatty substances; iv) one or more plasticizers; and
v) optionally one or more cosmetic active agents chosen from f) dyes, g) pigments; h) active agents for caring for keratin materials, notably the skin, and j) UV (A) and/or (B) screening agents, and also m) mixtures thereof.
[0022] More particularly, the subject of the invention relates to the use of the oily dispersion (A) as defined previously for treating keratin materials, notably human keratin materials such as the hair, the eyelashes, the eyebrows or the skin, preferably for dyeing keratin fibers and/or for shaping keratin fibers such as the hair, for caring for keratin materials, notably the skin, and/or for making up keratin materials such as the hair or the skin.
[0023] A subject of the invention is also the oily dispersion (A) as defined previously, and also a process for treating keratin materials, notably human keratin materials such as the hair, the eyelashes, the eyebrows or the skin, comprising the application to said materials of the oily dispersion (A) as defined previously.
[0024] A subject of the invention is also a multi-compartment kit or device comprising the ingredients i) to iv) and optionally v) as defined previously, in which the ingredients i) to iii) are in the same compartment, iv) is in another compartment, and optionally v) is in another compartment, or in the compartment with i) to iii), or in the compartment with iv).
[0025] The oily dispersion (A) and the process for treating keratin materials as defined above make it possible to obtain, after application to said materials, a residual film which adheres well to said materials while at the same time remaining elastic, showing little or no fragmentation, and little or no detachment, and which is notably resistant to shampoo washing, sebum, sweat and/or water, but also to fatty substances, notably dietary fats such as oils, notably to sebum. Furthermore, the dispersion is easy to use in compositions, notably cosmetic compositions, is easy to manufacture and remains stable over time. Specifically, the oily dispersion (A) in accordance with the present invention makes it possible to obtain deposits that are very resistant to external attacking factors, notably to sebum and to the fatty substances found in food, in particular liquid fatty substances such as plant oils and in particular olive oil. It appears that the makeup produced with at least one oily dispersion (A), notably lip makeup, shows no color fragmentation after application, and is resistant to external attacking factors such as liquid fatty substances, in particular with respect to plant oils such as olive oil. Furthermore, the makeup products obtained with the oily dispersions (A) are very esthetic, comfortable, easy to apply and glossy. Furthermore, these dispersions of polymer particles are found at a high solids content in the hydrocarbon-based liquid fatty substance(s) iii). It appears that the application of the oily dispersions (A) of the invention to keratin fibers makes it possible to obtain homogeneous coatings that are persistent with respect to external attacking factors (sunlight, water, shampoo washing, perspiration, sebum, etc.).
[0026] In addition, when the composition comprises one or more dyes and/or pigments, the colored keratin materials according to the invention have a coloring that is visible on all types of materials, notably on dark keratin materials, in a persistent manner with respect to soaps, shower gels or shampoos, while at the same time preserving the physical qualities of the keratin material. Such a coloring is in particular resistant to the external attacking factors to which the keratin fibers, notably the hair, may be subjected, such as daily blow-drying, brushing and styling, and perspiration. The use of the oily dispersion (A) on keratin materials, in particular on keratin fibers, makes it possible to obtain a smooth, homogeneous deposit. Moreover, it has been observed, surprisingly, that the keratin fibers remain perfectly individualized, and can be styled without any problem.

- ethers containing 7 to 30 carbon atoms;
- ketones containing 8 to 30 carbon atoms;
- aliphatic fatty monoalcohols containing 12 to 30 carbon atoms, the hydrocarbon-based chain not including any substitution groups; and
- mixtures thereof.
[0097] Advantageously, the hydrocarbon-based liquid fatty substance(s) of the invention are apolar, i.e. formed solely of carbon and hydrogen atoms.
[0098] The hydrocarbon-based liquid fatty substance(s) are preferably chosen from hydrocarbon-based oils containing from 8 to 14 carbon atoms, which are in particular volatile, more particularly the apolar oils described previously.
[0099] Preferentially, the liquid fatty substance(s) iii) of the invention are chosen from alkanes such as dodecane, isododecane, fatty alcohols such as octyldodecanol, esters such as isononyl isononanoate, cocoyl caprylate/caprate and mixtures thereof, more preferentially alkanes.
[00100] More particularly, the liquid fatty substance(s) iii) of the invention are chosen from linear or branched Ce-C , preferably Cs-Cu, more preferentially C9-C13 and even more preferentially C9-C12 alkanes, and even more preferentially the alkanes are volatile. More particularly, the liquid fatty substance(s) iii) of the invention are volatile and are chosen
from undecane, dodecane, isododecane, tridecane, and a mixture thereof notably comprising dodecane, isododecane or a mixture of undecane and tridecane.
[00101] Preferentially, the liquid fatty substance(s) iii) of the invention are isododecane.
[00102] According to another advantageous embodiment of the invention, the liquid fatty substance(s) iii) are a mixture of nonvolatile oil(s) and volatile oil(s); preferably, the mixture comprises, as volatile oil, undecane, dodecane, isododecane or tridecane, more preferentially isododecane. A mixture of volatile oil and nonvolatile oil that may be mentioned is the mixture of isododecane and of isononyl isononanoate.
[00103] More preferentially, when the fatty substance(s) are a mixture of volatile oil and of nonvolatile oil, the amount of volatile oil is greater than the amount of nonvolatile oil.
[00104] In particular, in the mixture, the nonvolatile oil is a phenyl silicone oil, preferably chosen from pentaphenyl silicone oils.
[00105] Method for preparing the dispersion (A)
[00106] Without this being limiting, in general, the dispersion according to the invention may be prepared in the following manner:
- The polymerization is performed in “dispersion" in nonaqueous medium, i.e. by precipitation of the polymer being formed, with protection of the formed particles with one or more stabilizers ii), preferably only one type of stabilizer ii) chosen from d) and e) as defined previously.
- In a first step, the stabilizing polymer (or stabilizer ii)) is prepared by mixing the constituent monomer(s) of the stabilizing polymer d) or e) with v) a free-radical initiator, in a solvent known as the synthesis solvent, and by polymerizing these monomers; and then
- In a second step, the constituent monomer(s) of the polymer of the particles i) are added to the stabilizing polymer formed in the preceding step and polymerization of these added monomers is performed in the presence of the free-radical initiator.
[00107] When the nonaqueous medium is a nonvolatile hydrocarbon-based liquid fatty substance iii), the polymerization may be performed in an apolar organic solvent (synthesis solvent), followed by adding the non-volatile hydrocarbon-based liquid fatty substance (which must be miscible with said synthesis solvent) and selectively distilling off the synthesis solvent.
[00108] The plasticizer(s) iv) and optionally one or more cosmetic active agents chosen from f) dyes and/or pigments, g) active agents for caring for keratin materials, notably the skin, and h) UV-screening agents and also j) mixtures thereof, may be added during the first step.
[00109] According to a first variant, the plasticizer(s) iv) are added during the second step. In this case, the plasticizer(s) iv) form an integral part of the particles i) and stabilizers ii) in the oil iii).
[00110] The term “integral part” means that the plasticizer(s) have reacted chemically with the particle(s) i) and/or with the stabilizer(s) ii), notably with i) during the polymerization.
[00111] According to a second preferred variant, the plasticizer(s) iv) are added after the second step, in a third step.
[00112] According to a third preferred variant, said cosmetic active agent(s) are added during the second step with said plasticizer(s) iv) or after the second step or even after the third step. It follows that in the second and third variants, the plasticizer(s) iv) do not form an integral part of the particle(s) i) and of the stabilizer(s) ii).
[00113] More particularly, the dispersion (A) then comprises: one or more particles i) (preferentially constituting the ethylenic polymeric core derived from homopolymers a) or the copolymers b) or c), as defined previously) associated with ii) one or more stabilizers (preferentially ii) being at the polymeric surface of said cores i), derived from the homopolymer d) and the copolymers e) as defined previously); one or more liquid fatty substances iii); one or more plasticizers iv); and optionally one or more cosmetic active agents chosen from f) dyes, g) pigments; h) active agents for caring for keratin materials, notably the skin, and j) UV (A) and/or (B) screening agents, and also m) mixtures thereof; it being understood that the plasticizer(s) iv) do not form an integral part of the particle(s) i) and of the stabilizer(s) ii).
[00114] A synthesis solvent which is such that the monomers of the polymeric stabilizer(s) ii) and the free-radical initiator v) are soluble therein, and such that the polymer particles i) obtained are insoluble therein, so that they precipitate therefrom during their formation, is preferably chosen. Preferably, the synthesis solvent also dissolves the plasticizer(s) iv) of the invention.
[00115] In particular, the synthesis solvent chosen is one which is an apolar, organic solvent, preferably chosen from liquid fatty substances iii), in particular alkanes such as heptane, cyclohexane, undecane, dodecane, isododecane or tridecane, preferably isododecane.
[00116] When the nonaqueous medium is a volatile hydrocarbon-based liquid fatty substance iii), the polymerization may be performed directly in said oil, which thus also acts as synthesis solvent. The monomers should also be soluble therein, as should the free-radical initiator, and the polymer of the particles i) which is obtained should be insoluble therein.
[00117] The monomers are preferably present in the synthesis solvent, before polymerization, in a proportion of from 15% to 45% by weight. The total amount of the monomers may be present in the solvent before the start of the reaction, or a portion of the monomers may be added gradually as the polymerization reaction proceeds.
[00118] The polymerization is preferentially performed in the presence v) of one or more radical initiators which may be any initiator known to those skilled in the art for radical polymerization, such as peroxide or azo initiators, redox couples and photochemical initiators.
[00119] The following types of initiator may notably be mentioned:
- peroxide, in particular chosen from tert-butyl peroxy-2-ethylhexanoate: Trigonox 21S; 2,5- dimethyl-2,5-bis(2-ethylhexanoylperoxy)hexane: Trigonox 141 ; tert-butyl peroxypivalate: Trigonox 25C75 from AkzoNobel; or
- azo, in particular chosen from AIBN: azobisisobutyronitrile; V50: 2,2’-azobis(2- amidinopropane) dihydrochloride.
[00120] The polymerization is preferably performed at a temperature ranging from 70°C to 110°C and at atmospheric pressure.
[00121] The polymer particles i) are surface-stabilized, when they are formed during the polymerization, by means of the stabilizer ii).
[00122] The stabilization may be performed by any known means, and in particular by direct addition of the stabilizer ii), during the polymerization.
[00123] The stabilizer ii) is preferably also present in the mixture before polymerization of the monomers of the polymer of the particles i). However, it is also possible to add it continuously, notably when the monomers of the particles i) are also added continuously. [00124] From 2% to 40% by weight and notably from 4% to 30% by weight of the stabilizer(s) may be used relative to the total weight of monomers used (stabilizers ii) + polymer particles i)), preferably from 5% to 25% by weight and preferably from 4.5% to 20% by weight, relative to the total weight of the dispersion (A).
[00125] The polymer particle dispersion (A) advantageously comprises from 30% to 65% by weight of solids relative to the total weight of said dispersion and preferably from 40% to 60% by weight relative to the total weight of said dispersion.
[00126] The composition according to the invention preferably comprises a solids (or active material) content of polymers of particle i) + dispersing polymers ii) ranging from 10% to 80% by weight, relative to the total weight of composition (A), preferably ranging from 20% to 60% by weight, notably 30% to 50% by weight, relative to the total weight of composition (A).
[00127] According to a preferred embodiment of the invention, the dispersion (A) according to the invention is an anhydrous composition.
[00128] According to another embodiment of the present invention, the dispersion (A) is in inverse emulsion, i.e. of water-in-oil (W/O) type. In this case, the composition comprises one or more surfactants, which are preferably nonionic. The inverse emulsions of (A) are preferably chosen when the dispersions (A) are intended for makeup, and notably for making up the eyelashes and/or eyebrows.
[00129] In a particular preparation method, the statistical stabilizing polymer ii) is prepared in a first step. This stabilizing polymer is soluble in an apolar organic solvent of alkane type, such as isododecane.
[00130] Next, in a second step, the polymer particles i) are synthesized in the presence of the stabilizing polymer ii).
[00131] Preferentially, a solution of stabilizing polymer ii) in the hydrocarbon-based liquid fatty substance(s) iii) is prepared for the final dispersion, and the polymerization of the monomers which form the core of the particle is performed in the presence of this stabilizer ii).
[00132] The stabilizing polymer ii) may be prepared by radical polymerization optionally in the presence of a polymerization initiator v) as defined previously.
[00133] In a second step, the monomers which form the core of the particle i) may be polymerized in the presence of said stabilizing polymer ii). This second step may be a conventional radical polymerization.
[00134] The dispersions are prepared in the presence of one or more hydrocarbon-based liquid fatty substances iii), preferably in an apolar organic solvent, in particular of alkane type such as isododecane, according to an industrially feasible process.
[00135] The dispersions according to the invention are thus finally formed from polymer particles, of relatively large diameter (preferably greater than 100 nm), and give glossy film-forming deposits that are resistant to fatty substances at the observation temperature (25°C).
[00136] Furthermore, since said dispersion is in oily medium, it becomes easy to formulate it in cosmetic compositions based on oily medium commonly used in cosmetics, in particular anhydrous media or in the fatty phases of emulsions. Emulsions that may be mentioned include “inverse emulsions” of water-in-oil (W/O) type or “direct” emulsions of oil-in-water (O/W) type.
[00137] The polymer according to the invention finds a quite particular application in the cosmetic field, notably in the makeup field and notably in lipsticks, glosses (lip glosses) and eyeshadows and mascaras.
[00138] iv) The plasticizer(s)
[00139] The term “plasticizer” or “plasticizing agent’ means an organic chemical compound, which is in solid state or in liquid state, at room temperature (20°C) and at atmospheric pressure, and which is generally added to a composition comprising different types of polymerizable ingredients (monomers) to make the polymers more supple, more flexible, and/or to improve their mechanical strength. Plasticizers are known to those skilled in the art; mention may be made, for example, of “Plasticizers”, Encyclopedia of
polymer Science and Technology, Helmut Reinecke, Rodrigo Navarro, Monica Perez, https://doi.Org/10.1002/0471440264. pst245.pub215 September 2011.

The plasticizers are also organic compounds consisting of carbon and hydrogen atoms and of one or more heteroatoms chosen from oxygen, sulfur and silicon atoms, in particular chosen from oxygen atoms, preferably at least 2 heteroatoms, even more preferentially between 2 and 10 heteroatoms, and which may contain one or more aryl groups. In particular, the plasticizers according to the invention comprise one or more ester functions, notably from 1 to 5 ester functions such as citrates, phthalates, adipates or benzoates, or esters Ra-C(O)-O-Rb or Ra-O-C(O)-Rb in which Ra denotes a branched (Ci-Ce)alkyl group such as a tert-butyl and Rb denotes a branched, preferably saturated, (Cs-C2o)alkyl group such as an isodecyl group or an isostearyl group.

[00152] According to a particular embodiment of the invention, the plasticizer(s) are present in an amount of between 0.1% and 50% by weight and preferably from 0.5% to 30% by weight relative to the total weight of the polymer(s) a) to e) of the particles.
[00153] v) The cosmetic active a ent(s)
[00154] According to a particular embodiment of the invention, the dispersion (A) of the invention comprises one or more cosmetic active agents chosen from f) dyes, g) pigments; h) active agents for caring for keratin materials, and j) UV (A) and/or (B) screening agents, and also k) mixtures thereof.

[00160] The pigments are white or colored solid particles which are naturally insoluble in the hydrophilic and lipophilic liquid phases usually employed in cosmetics or which are rendered insoluble by formulation in the form of a lake, where appropriate. More particularly, the pigments have little or no solubility in aqueous-alcoholic media.
[00161] The pigments that may be used are notably chosen from the organic and/or mineral pigments known in the art, notably those described in Kirk-Othmer’s Encyclopedia of Chemical Technology and in Ullmann’s Encyclopedia of Industrial Chemistry. Pigments that may notably be mentioned include organic and mineral pigments such as those defined and described in Ullmann’s Encyclopedia of Industrial Chemistry “Pigments, organic”, 2005 Wiley- VCH Verlag GmbH & Co. KGaA, Weinheim 10.1002/14356007.a20 371 and ibid, “Pigments, Inorganic, 1. General” 2009 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim 10.1002/14356007. a20_243. pub3
[00162] These pigments may be in pigment powder or paste form. They may be coated or uncoated.
[00163] The pigments may be chosen, for example, from mineral pigments, organic pigments, lakes, pigments with special effects such as nacres or glitter flakes, and mixtures thereof.
[00164] The pigment may be a mineral pigment. The term “mineral pigment” refers to any pigment that satisfies the definition in Ullmann’s encyclopedia in the chapter on inorganic pigments. Among the mineral pigments that are useful in the present invention, mention may be made of iron oxides, chromium oxides, manganese violet, ultramarine blue, chromium hydrate, ferric blue and titanium oxide.
[00165] The pigment may be an organic pigment.
[00166] The term “organic pigment” refers to any pigment that satisfies the definition in Ullmann’s encyclopaedia in the chapter on organic pigments.
[00167] The organic pigment may notably be chosen from nitroso, nitro, azo, xanthene, quinoline, anthraquinone, phthalocyanine, metal complex type, isoindolinone, isoindoline, quinacridone, perinone, perylene, diketopyrrolopyrrole, thioindigo, dioxazine, triphenylmethane and quinophthalone compounds.
[00168] In particular, the white or colored organic pigments may be chosen from carmine, carbon black, aniline black, azo yellow, quinacridone, phthalocyanine blue, the blue pigments codified in the Color Index under the references Cl 42090, 69800, 69825, 74100, 74160, the yellow pigments codified in the Color Index under the references Cl 11680, 11710, 19140, 20040, 21100, 21108, 47000, 47005, the green pigments codified in the Color Index under the references Cl 61565, 61570, 74260, the orange pigments codified in the Color Index under the references Cl 11725, 45370, 71105, the red pigments codified in the Color Index under the references Cl 12085, 12120, 12370, 12420, 12490, 14700, 15525, 15580, 15620, 15630, 15800, 15850, 15865, 15880, 26100, 45380, 45410, 58000, 73360, 73915, 75470, the pigments obtained by oxidative polymerization of indole or phenol derivatives as described in patent FR 2 679 771.
[00169] Mention may also be made, by way of example, of pigment pastes of organic pigments, such as the products sold by Hoechst under the names:
- Cosmenyl Yellow 10G: Pigment Yellow 3 (Cl 11710);
- Cosmenyl Yellow G: Pigment Yellow 1 (Cl 11680);

These composite pigments may notably be composed of particles including a mineral core, at least one binder for attaching the organic pigments to the core, and at least one organic pigment which at least partially covers the core.
[00171] The organic pigment may also be a lake. The term “lake” refers to dyes adsorbed onto insoluble particles, the assembly thus obtained remaining insoluble during use.
[00172] The inorganic substrates onto which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate or calcium aluminum borosilicate, and aluminum.
[00173] Mention may be made, among the dyes, of carminic acid.

[00174] An example of a lake that may be mentioned is the product known under the following name: D&C Red 7 (Cl 15 850:1).
[00175] The pigment may also be a pigment with special effects. The term “pigments with special effects” means pigments that generally create a colored appearance (characterized by a certain shade, a certain vivacity and a certain level of luminance) that is non-uniform and that changes as a function of the conditions of observation (light, temperature, angles of observation, etc.). They thereby differ from colored pigments, which afford a standard uniform opaque, semi-transparent or transparent shade.
[00176] Several types of pigments with special effects exist: those with a low refractive index, such as fluorescent or photochromic pigments, and those with a higher refractive index, such as nacres, interference pigments or glitter flakes.
[00177] Examples of pigments with special effects that may be mentioned include nacreous pigments such as mica coated with titanium or with bismuth oxychloride, colored nacreous pigments such as mica covered with titanium and with iron oxides, mica covered with iron oxide, mica covered with titanium and notably with ferric blue or with chromium oxide, mica covered with titanium and with an organic pigment as defined previously, and also nacreous pigments based on bismuth oxychloride. Nacreous pigments that may be mentioned include the Cellini nacres sold by BASF (mica-TiO2-lake), Prestige sold by Eckart (mica-TiO2), Prestige Bronze sold by Eckart (mica-Fe2O3), and Colorona sold by Merck (mica-TiO2-Fe2O3).
[00178] Mention may also be made of the gold-colored nacres sold notably by the company BASF under the name Brilliant gold 212G (Timica), Gold 222C (Cloisonne), Sparkle gold (Timica), Gold 4504 (Chromalite) and Monarch gold 233X (Cloisonne); the bronze nacres sold notably by the company Merck under the name Bronze fine (17384) (Colorona) and Bronze (17353) (Colorona) and by the company BASF under the name Super bronze (Cloisonne); the orange nacres sold notably by the company BASF under the name Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by the company Merck under the name Passion orange (Colorona) and Matte orange (17449) (Microna);
the brown nacres sold notably by the company BASF under the name Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); the nacres with a copper tint sold notably by the company BASF under the name Copper 340A (Timica); the nacres with a red tint sold notably by the company Merck under the name Sienna fine (17386) (Colorona); the nacres with a yellow tint sold notably by the company BASF under the name Yellow (4502) (Chromalite); the red nacres with a gold tint sold notably by the company BASF under the name Sunstone G012 (Gemtone); the pink nacres sold notably by the company BASF under the name Tan opale G005 (Gemtone); the black nacres with a gold tint sold notably by the company BASF under the name Nu antique bronze 240 AB (Timica), the blue nacres sold notably by the company Merck under the name Matte blue (17433) (Microna), the white nacres with a silvery tint sold notably by the company Merck under the name Xirona Silver, and the golden-green pink-orange nacres sold notably by the company Merck under the name Indian summer (Xirona), and mixtures thereof.
[00179] Still as examples of nacres, mention may also be made of particles including a borosilicate substrate coated with titanium oxide.
[00180] Particles comprising a glass substrate coated with titanium oxide are notably sold under the name Metashine MC1080RY by the company Toyal.
[00181] Finally, examples of nacres that may also be mentioned include polyethylene terephthalate glitter flakes, notably those sold by the company Meadowbrook Inventions under the name Silver 1 P 0.004X0.004 (silver glitter flakes). It is also possible to envisage multilayer pigments based on synthetic substrates, such as alumina, silica, calcium sodium borosilicate, calcium aluminum borosilicate and aluminum.
[00182] The pigments with special effects may also be chosen from reflective particles, i.e. notably from particles whose size, structure, notably the thickness of the layer(s) of which they are made and their physical and chemical nature, and surface state, allow them to reflect incident light. This reflection may, where appropriate, have an intensity sufficient to create at the surface of the composition or of the mixture, when it is applied to the support to be made up, highlight points that are visible to the naked eye, i.e. more luminous points that contrast with their environment making them appear to sparkle.
[00183] The reflective particles may be selected so as not to significantly alter the coloring effect generated by the coloring agents with which they are combined, and more particularly so as to optimize this effect in terms of color rendition. They may more particularly have a yellow, pink, red, bronze, orange, brown, gold and/or coppery color or tint.
[00184] These particles may have varied forms and may notably be in platelet or globular form, in particular in spherical form.
[00185] The reflective particles, whatever their form, may or may not have a multilayer structure and, in the case of a multilayer structure, may have, for example, at least one layer of uniform thickness, notably of a reflective material.
[00186] When the reflective particles do not have a multilayer structure, they may be composed, for example, of metal oxides, notably titanium or iron oxides obtained synthetically.
[00187] When the reflective particles have a multilayer structure, they may include, for example, a natural or synthetic substrate, notably a synthetic substrate at least partially coated with at least one layer of a reflective material, notably of at least one metal or metallic material. The substrate may be made of one or more organic and/or mineral materials.
[00188] More particularly, it may be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, notably aluminosilicates and borosilicates, and synthetic mica, and mixtures thereof, this list not being limiting.
[00189] The reflective material may include a layer of metal or of a metallic material.
[00190] Reflective particles are notably described in JP-A-09188830, JP-A-10158450, JP-A-10158541 , JP-A-07258460 and JP-A-05017710.
[00191] Again as an example of reflective particles including a mineral substrate coated with a layer of metal, mention may also be made of particles including a silver-coated borosilicate substrate.
[00192] Particles with a silver-coated glass substrate, in the form of platelets, are sold under the name Microglass Metashine REFSX 2025 PS by the company Toyal. Particles with a glass substrate coated with nickel/chromium/molybdenum alloy are sold under the names Crystal Star GF 550 and GF 2525 by this same company.
[00193] Use may also be made of particles comprising a metal substrate, such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze or titanium, said substrate being coated with at least one layer of at least one metal oxide, such as titanium oxide, aluminum oxide, iron oxide, cerium oxide, chromium oxide, silicon oxides and mixtures thereof.
[00194] Examples that may be mentioned include aluminum powder, bronze powder or copper powder coated with SiO2, sold under the name Visionaire by the company Eckart. [00195] Mention may also be made of pigments with an interference effect which are not attached to a substrate, such as liquid crystals (Helicones HC from Wacker) or interference holographic glitter flakes (Geometric Pigments or Spectra f/x from Spectratek). Pigments with special effects also comprise fluorescent pigments, whether these are substances that are fluorescent in daylight or that produce an ultraviolet fluorescence, phosphorescent pigments, photochromic pigments, thermochromic pigments and quantum dots, sold, for example, by the company Quantum Dots Corporation.
[00196] The variety of pigments that may be used in the present invention makes it possible to obtain a wide range of colors, and also particular optical effects such as metallic effects or interference effects.
[00197] The size of the pigment used in the composition according to the present invention is generally between 10 nm and 200 pm, preferably between 20 nm and 80 pm and more preferentially between 30 nm and 50 pm.
[00198] The pigments may be dispersed in the composition by means of a dispersant.
[00199] The dispersant serves to protect the dispersed particles against agglomeration or flocculation thereof. This dispersant may be a surfactant, an oligomer, a polymer or a mixture of several thereof, bearing one or more functionalities with strong affinity for the surface of the particles to be dispersed. In particular, they may become physically or chemically attached to the surface of the pigments. These dispersants also contain at least one functional group that is compatible with or soluble in the continuous medium. In particular, esters of 12-hydroxystearic acid in particular and of Cs to C20 fatty acid and of polyols such as glycerol or diglycerol are used, such as poly(12-hydroxystearic acid) stearate with a molecular weight of approximately 750 g/mol, such as the product sold under the name Solsperse 21 000 by the company Avecia, polyglyceryl-2 dipolyhydroxystearate (CTFA name) sold under the reference Dehymyls PGPH by the company Henkel, or polyhydroxystearic acid such as the product sold under the reference Arlacel P100 by the company Uniqema, and mixtures thereof.
[00200] As other dispersants that may be used in the compositions of the invention, mention may be made of quaternary ammonium derivatives of polycondensed fatty acids, for instance Solsperse 17 000 sold by the company Avecia, and polydimethylsiloxane/oxypropylene mixtures such as those sold by the company Dow Corning under the references DC2-5185 and DC2-5225 C.
[00201] The pigments used in the composition may be surface-treated with an organic agent.
[00202] Thus, the pigments surface-treated beforehand that are useful in the context of the invention are pigments which have been completely or partially subjected to a surface treatment of chemical, electronic, electrochemical, mechanochemical or mechanical nature with an organic agent, such as those described notably in Cosmetics and Toiletries, February 1990, Vol. 105, pages 53-64, before being dispersed in the composition in accordance with the invention. These organic agents may be chosen, for example, from waxes, for example carnauba wax and beeswax; fatty acids, fatty alcohols and derivatives thereof, such as stearic acid, hydroxystearic acid, stearyl alcohol, hydroxystearyl alcohol and lauric acid and derivatives thereof; anionic surfactants; lecithins; sodium, potassium, magnesium, iron, titanium, zinc or aluminum salts of fatty acids, for example aluminum stearate or laurate; metal alkoxides; polyethylene; (meth)acrylic polymers, for example polymethyl methacrylates; polymers and copolymers containing acrylate units; alkanolamines; silicone compounds, for example silicones, notably polydimethylsiloxanes; organofluorine compounds, for example perfluoroalkyl ethers; fluorosilicone compounds.
[00203] The surface-treated pigments that are useful in the composition may also have been treated with a mixture of these compounds and/or may have undergone several surface treatments.
[00204] The surface-treated pigments that are useful in the context of the present invention may be prepared according to surface-treatment techniques that are well known to those skilled in the art, or may be commercially available as is.
[00205] Preferably, the surface-treated pigments are coated with an organic layer.
[00206] The organic agent with which the pigments are treated may be deposited on the pigments by evaporation of solvent, chemical reaction between the molecules of the surface agent or creation of a covalent bond between the surface agent and the pigments. [00207] The surface treatment may thus be performed, for example, by chemical reaction of a surface agent with the surface of the pigments and creation of a covalent bond between the surface agent and the pigments or the fillers. This method is notably described in patent US 4 578 266.
[00208] An organic agent covalently bonded to the pigments will preferably be used.
[00209] The agent for the surface treatment may represent from 0.1% to 50% by weight relative to the total weight of the surface-treated pigment, preferably from 0.5% to 30% by weight and even more preferentially from 1% to 20% by weight relative to the total weight of the surface-treated pigment.
[00210] Preferably, the surface treatments of the pigments are chosen from the following treatments:
- a PEG-silicone treatment, such as the AQ surface treatment sold by LCW;
- a methicone treatment, such as the SI surface treatment sold by LCW;
- a dimethicone treatment, such as the Covasil 3.05 surface treatment sold by LCW;
- a dimethicone/trimethylsiloxysilicate treatment, such as the Covasil 4.05 surface treatment sold by LCW;
- a magnesium myristate treatment, such as the MM surface treatment sold by LCW;

- a perfluoroalkyl phosphate treatment, such as the PF surface treatment sold by Daito;
- an acrylate/dimethicone copolymer and perfluoalkyl phosphate treatment, such as the FSA surface treatment sold by Daito;
- a polymethylhydrosiloxane/perfluoroalkyl phosphate treatment, such as the FS01 surface treatment sold by Daito;
- an acrylate/dimethicone copolymer treatment, such as the ASC surface treatment sold by Daito;
- an isopropyl titanium triisostearate treatment, such as the ITT surface treatment sold by
Daito;
- an acrylate copolymer treatment, such as the APD surface treatment sold by Daito;
- a perfluoroalkyl phosphate/isopropyl titanium triisostearate treatment, such as the PF + ITT surface treatment sold by Daito.

[00241] EXAMPLES
[00242] The dispersions of polymer particles presented in the various examples were prepared in 1 liter pilot reactors. The syntheses are performed in an apolar aprotic organic solvent such as isododecane.
[00243] The synthetic process is identical for all the dispersions obtained. In a first step, the statistical stabilizing polymer is synthesized by reaction between the C9-C22 alkyl (meth)acrylate and a small amount of one or two different (Ci-C4)alkyl (C1- C4)(alkyl)acrylates, preferably (Ci-C4)alkyl (meth)acrylate such as methyl acrylate or methyl acrylate + ethyl acrylate.
[00244] The reaction is performed at 90°C for 2 hours. In the second step, the particle core is obtained after introducing the (Ci-C4)alkyl (Ci-C4)(alkyl)acrylate ethylenically unsaturated monomers, preferably (Ci-C4)alkyl (meth)acrylate and optionally (C1- C4)(alkyl)acrylic acid, preferably (meth)acrylic acid such as acrylic acid; into the reaction medium containing the stabilizing polymer. This second step is performed at 90°C for 5 hours.
[00245] Several purification steps by distillation of the solvent (isododecane), also known as “strippings”, may be performed at the end of the synthesis to remove the residual unreacted monomers.
[00246] The percentage of active material in the hydrocarbon-based liquid fatty substance(s) iii) such as isododecane is finally between 40% and 55%, such as 50%.
[00247] The polymerization initiator is Trigonox T21S. The CAS and the supplier of this initiator are given in Table 2: Polymerization initiator used in the various examples [00248] [Table 1]:
[00249] Examples of implementation of the invention
[00250] Synthesis of the oily dispersions with a stabilizer bearing a C9-C22 alkyl group [00251] A synthetic example is presented below for the production of an oily dispersion with a C9-C22 alkyl (meth)acrylate stabilizer. For this example, stearyl methacrylate was used in combination with methyl acrylate for the stabilizing arm and methyl acrylate was adopted for the core of the particle.
[00252] Example of synthesis of a stearyl methacrylate/methyl acrylate oily dispersion Example 10 of FR 3 097 756
[00253] The oily dispersions are formed as a whole (polymer particles i) + polymeric stabilizer ii)) with 94.5% of methyl acrylate and 5.5% of stearyl methacrylate. The synthesis
of these oily dispersions was performed in a 1 liter pilot reactor. The synthesis is performed in two steps:
- In a first step, stearyl methacrylate is polymerized in isododecane in the presence of a small amount of methyl acrylate and of a radical initiator (T21S). In the first step, the stearyl methacrylate/methyl acrylate mass ratio is 85/15.
In the second step, the rest of the methyl acrylate is added in the presence of isododecane and of the radical initiator (T21S).
[00254] After stripping, the polymer is at a solids content of 50% in the isododecane. [00255] The ratios employed to obtain the stabilizer and the core are summarized in [00256] Table 2: Specific ratios in the stabilizer ii) and the core i) for the dispersion [00257] [Table 2]
[00259] Experimental protocol:
Isododecane, stearyl methacrylate, methyl acrylate and T21S are introduced as feedstock into the reactor. The medium is heated to 90°C (nominal medium temperature) under argon and with stirring. The solids content during this first step is 22%.
[0001] After heating for 2 hours, NMR indicates a stearyl methacrylate consumption of 99% (methyl acrylate consumption: 98%).
[0002] After 2 hours of reaction, isododecane is introduced. The medium is heated to 90°C.
[0003] Once the medium is at 90°C, methyl acrylate, isododecane and T21S are introduced over 1 hour by pouring. At the end of the introduction, the medium is milky.
[0004] After 7 hours of synthesis, virtually total consumption of the methyl acrylate and quantitative consumption of the stearyl methacrylate are obtained.
[0005] 400 mL of isododecane are then stripped out (the reaction progress is monitored by NMR).
[0006] Plasticizers iv)
[0007] Once the particles are dispersed in isododecane, the plasticizer is added. The amount of plasticizer added is 10% by mass relative to the total weight of the polymer of the particles (stabilizer + core). Thus, for 20% polymer active material of the particles, 2% by mass of plasticizer were added. The plasticizer was added at room temperature (20°C) with stirring. Once the particle dispersion + plasticizer mixture is homogeneous, the cosmetic active agents such as pigments are added, still at room temperature and with stirring.
[0008]
[0010] Evaluation on keratin material:
[0011] The various combinations were evaluated in terms of making up the skin.
[0012] A formulation containing a particle dispersion of the invention was prepared. This formulation was applied to a wet thickness of 50 pm onto two glass supports:
FP40 type support: FP40 (Trellborg, N4I01)* is an elastomeric substrate made of butadiene-acrylonitrile copolymer containing a diethylhexyl sebacate oil, which approximates to skin sebum, as plasticizer. When a polymer conveyed in isododecane is applied to this substrate, extraction of the plasticizer is performed, mimicking the contribution/impact of sebum on the Bioskin type support coating: elastomer support simulating a polyurethane elastomer skin reinforced with elastane (particular polyurethane) - manufactured by Beaulax (Japan).
[0013] The deposit was left to dry for 24 hours. After 24 hours of drying, the deposits were evaluated. After drying for one day, the BioSkin or FP40 plate is stretched, by hand force, this being done 10 times.
[0014] The result may then be observed on the formulation film (fragmentation or otherwise).
AM: Active Material
[0017] The in vitro substrate before deposition is 10 cm long and 6 cm wide. A coating measuring 6 cm in length and 5 cm in width is applied to this substrate. The substrate + coating assembly is stretched in the same manner with the same force for the various tests to achieve a 40% stretch in the direction of the length of the substrate + coating (14 cm).
[0018] The evaluation is then made visually as follows: +++ No visible striae
++ Between 1 and 5 visible striae
+ Between 5 and 10 visible striae
More than 10 visible striae.
[0019] Results:
[0020] [Table 6]
It is seen that the addition of plasticizer to the dispersion makes it possible, after application to the keratin materials and evaporation of the solvents, to obtain a film which adheres significantly more to the substrate than the comparative. In addition, the appearance of the film remains unchanged after stretching, i.e. esthetic satiny glossy red for dispersions 2 to 6.
