Description

[Technical Field]

[0001] The present invention aims to provide novel compositions for the care and / or make-up of keratinous materials, in particular the skin, comprising at least one silicone elastomer containing carboxylic acid functions and at least one copolymer based on a silicone resin and a silicone of the dimethiconol type. [Background technology]

[0002] Cosmetic makeup compositions are commonly used not only to impart attractive color to keratinous materials such as skin, but also to enhance the beauty of uneven skin and reduce the visibility of imperfections in removal such as pores and wrinkles by making it possible to conceal marks and pigmentation disorders.Many formulations have been developed so far.For many years, consumers have been seeking compositions that provide good wear properties of makeup effect over time, so as to avoid the need to reapply the composition too frequently.

[0003] One of the solutions proposed by the prior art to obtain good wear properties is the use of film-forming agents, which allow the composition, when applied, to form a more tacky, adhesive and durable film on the substrate after drying.However, the use of film-forming agents is not entirely satisfactory, since one of the problems encountered with such agents is the fact that they cause discomfort when used, especially due to the difficulty in spreading the composition.

[0004] Makeup compositions based on silicone elastomers containing carboxylic acid functional groups have already been proposed in the published literature (Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4, Patent Document 5, Non-Patent Document 1, Non-Patent Document 2), and these compositions have good performance in terms of wear properties and durability. However, these polymers are not completely satisfactory in terms of resistance to abrasion. Furthermore, silicone elastomers containing carboxylic acid functional groups generally have a texture that is difficult to pick up and apply, and tend to give makeup compositions with a soft and homogeneous consistency that is poorly fluid, making it difficult to pick up the product and spread it easily on the skin.

[0101] According to one embodiment, the composition of the present invention comprises isopropanol, ethanol and mixtures thereof.

[0102] According to an advantageous embodiment, the amount of monoalcohol varies from 0.1% to 10% by weight, preferably from 1% to 5% by weight relative to the total weight of the composition.

[0103] pigment According to a particular embodiment of the invention, the composition additionally comprises at least one pigment.

[0104] The term "pigments" means white or colored inorganic or organic particles that are insoluble in aqueous media and are intended to color and / or opacify the resulting composition and / or deposit. These pigments can be white or colored, inorganic and / or organic.

[0105] Preferably, the composition comprises at least 5% by weight of pigment, more preferentially from 5% to 40% by weight of pigment, in particular from 10% to 30% by weight, preferably from 10% to 20% by weight of pigment, relative to the total weight of the composition.

[0106] According to a particular embodiment, the pigments used according to the invention are chosen from inorganic pigments.

[0107] The term "inorganic pigment" means any pigment that meets the definition in the chapter on inorganic pigments of Ullmann's encyclopedia. Among the inorganic pigments that are useful in the present invention, mention may be made of zirconium oxide or cerium oxide and also zinc oxide, iron oxide (black, yellow or red) or chromium oxide, manganese violet, ultramarine blue, chromium hydrate and ferric blue, titanium dioxide, and metal powders such as aluminum powder and copper powder. The following inorganic pigments may also be used: Ta2O5, Ti3O5, Ti2O3, TiO, ZrO2 in a mixture with TiO2, ZrO2, Nb2O5, CeO2, ZnS.

[0108] The size of the pigments useful in connection with the present invention is generally greater than 100 nm and may range up to 10 μm, preferably between 200 nm and 5 μm, and more preferentially between 300 nm and 1 μm.

[0109] According to a particular embodiment of the invention, the pigments have a size characterized by D

[50] greater than 100 nm, possibly up to 10 μm, preferably ranging from 200 nm to 5 μm, and more preferentially from 300 nm to 1 μm.

[0110] The size is measured by static light scattering using a commercially available MasterSizer 3000® particle size analyzer from Malvern, which allows the measurement of the entire particle size distribution over a wide range that can extend from 0.01 μm to 1000 μm. The data are processed based on the Mie scattering theory. This theory is most suitable for particle size distributions in the submicron to several micron range; it allows the "effective" particle size to be measured. This theory is explained, inter alia, in the publication by Van de Hulst, H.C., Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.

[0111] D

[50] represents the maximum size of 50% by volume of the particles.

[0112] In the context of the present invention, inorganic pigments are more particularly iron oxide and / or titanium dioxide.

[0113] Inorganic pigments that may be used in the present invention may also include mother of pearl.

[0114] The term "mother of pearl" should be understood to mean any form of colored particles, which may or may not be iridescent, produced especially by certain mollusks in their exoskeleton or alternatively synthesized, and which have a color effect due to light interference.

[0115] The nacre can be selected from titanium dioxide-coated mica coated with iron oxide, titanium dioxide-coated mica coated with bismuth oxychloride, titanium dioxide-coated mica coated with chromium oxide, titanium dioxide-coated mica coated with organic dyes, and also pearlescent pigments such as pearlescent pigments based on bismuth oxychloride, which can also be mica particles having at least two successive layers of metal oxides and / or organic colorants superimposed on the surface of the mica particle.

[0116] Examples of nacre that may also be mentioned include natural mica coated with titanium oxide, iron oxide, natural pigments or bismuth oxychloride.

[0120] Among the pigments that can be used according to the invention, mention may also be made of those that have optical effects that differ from the simple conventional coloring effects, i.e. the unified and stabilized effects that are produced by conventional colorants, such as monochromatic pigments, etc. For the purposes of the present invention, the term "stabilized" means that there is no effect of color variability with the angle of observation or in response to temperature changes.

[0121] For example, the material can be selected from particles with metallic luster, goniochromatic colorants, diffractive pigments, thermochromic agents, optical brighteners and also fibers, in particular interference fibers. Naturally, these various materials can be combined to provide the simultaneous display of two effects, indeed even the novel effect according to the invention.

[0122] The particles with metallic luster that can be used in the present invention are in particular: - particles of at least one metal and / or of at least one metal derivative, - particles comprising a single-material or multi-material organic or inorganic substrate at least partially covered with at least one layer having a metallic luster comprising at least one metal and / or at least one metal derivative, and - a mixture of said particles is selected from.

[0124] The term "metal derivatives" refers to compounds derived from metals, in particular oxides, fluorides, chlorides and sulfides.

[0125] As examples of these particles, mention may be made of aluminum particles such as those sold under the name Starbrite 1200EAC® by Silberline and under Metalure® by Eckart.

[0126] Mention may also be made of metal powders of copper or alloy mixtures, such as the reference 2844 sold by the company Radium Bronze, metal pigments such as aluminum or bronze, such as those sold under the name Rotosafe 700® by the company Eckart, silica-coated aluminum particles sold under the name Visionaire Bright Silver® by the company Eckart, and metal alloy particles, such as silica-coated bronze (copper and zinc alloy) powder sold under the name Visionaire Bright Natural Gold® by the company Eckart.

[0127] They may also be particles containing a glass substrate, such as those sold by Nippon Sheet Glass Co. under the name Microglass Metashine®.

[0128] Goniochromatic colorants may be selected, for example, from multilayer interference structures and liquid crystal colorants.

[0129] Examples of symmetrical multilayer interference structures that can be used in the compositions produced according to the invention are, for example, the following structures: Al / SiO2 / Al / SiO2 / Al (pigments with this structure are sold by DuPont de Nemours); Cr / MgF2 / Al / MgF2 / Cr (pigments with this structure are sold under the name Chromaflai® by Flex); MoS2 / SiO2 / Al / SiO2 / MoS2; Fe2O3 / SiO2 / Al / SiO2 / Fe2O3 and Fe2O3 / SiO2 / Fe2O3 / SiO2 / Fe2O3 (pigments with these structures are sold under the name Sicopearl® by BASF); M SiO2 / mica-oxide / SiO2 / MoS2; Fe2O3 / SiO2 / mica-oxide / SiO2 / Fe2O3; TiO2 / SiO2 / TiO2 and TiO2 / Al2O3 / TiO2; SnO / TiO2 / SiO2 / TiO2 / SnO; Fe2O3 / SiO2 / Fe2O3; SnO / mica / TiO2 / SiO2 / TiO2 / mica / SnO (pigments with these structures are sold under the name Xirona® by Merck (Darmstadt)). By way of example, these pigments may be the pigment with silica / titanium oxide / tin oxide structure sold under the name Xirona Magic® by Merck, the pigment with silica / brown iron oxide structure sold under the name Xirona Indian Summer® by Merck, and the pigment with silica / titanium oxide / mica / tin oxide structure sold under the name Xirona Caribbean Blue® by Merck. Mention may also be made of Infinite Colors pigments from Shiseido. Different effects are obtained depending on the thickness and nature of the various layers. Thus, with an Fe2O3 / SiO2 / Al / SiO2 / Fe2O3 structure, the color changes from green-gold to reddish-gray for SiO2 layers of 320-350 nm; from red to gold for SiO2 layers of 380-400 nm; from purple to green for SiO2 layers of 410-420 nm; and from copper to red for SiO2 layers of 430-440 nm.

[0130] As examples of pigments with a polymeric multilayer structure, mention may be made of those sold by 3M under the name Color Glitter®.

[0131] As liquid crystal goniochromatic particles, for example, those sold by Chenix and those sold under the name Helicone® HC by Wacker can be used.

[0132] Hydrophobic coated pigments According to a particular embodiment of the invention, the composition according to the invention comprises at least one pigment, in particular as described in more detail below, coated with at least one lipophilic or hydrophobic compound.

[0133] This type of pigment is particularly advantageous insofar as it can be considered in large quantities together with large quantities of water, and, in addition, insofar as they are treated with hydrophobic compounds, they exhibit a marked affinity for the oily phase, so that they can be transported.

[0134] Of course, the composition according to the invention may also contain uncoated pigments.

[0135] The coating may also include at least one additional non-lipophilic compound.

[0136] For the purposes of the present invention, a "coating" of a pigment according to the present invention generally refers to a total or partial surface treatment of the pigment with a surface agent that is absorbed, adsorbed or grafted onto said pigment.

[0137] The surface-treated pigments can be prepared according to surface treatment techniques of a chemical, electronic, mechanochemical or mechanical nature well known to those skilled in the art. Commercially available products can also be used.

[0138] The surface agent can be absorbed, adsorbed or grafted onto the pigment by solvent evaporation, chemical reaction and the formation of a covalent bond.

[0139] According to one alternative, the surface treatment consists of a coating of pigments.

[0140] The coating may represent from 0.1% to 20% by weight, in particular from 0.5% to 5% by weight, relative to the total weight of the coated pigment.

[0141] The coating can be brought about, for example, by adsorption of a liquid surface agent onto the surface of the solid particles by simply mixing the solid particles with the liquid surface agent under stirring, optionally with heating, before incorporation of the particles into the other ingredients of the makeup or care composition.

[0142] The coating can be produced, for example, by chemical reaction of the surface agent with the surface of the solid pigment particle and the formation of a covalent bond between the surface agent and the particle, a process described, inter alia, in U.S. Pat. No. 4,578,266.

[0143] Chemical surface treatment may involve diluting a surface agent in a volatile solvent, dispersing a pigment in this mixture, and then slowly evaporating the volatile solvent, so that the surface agent is deposited on the surface of the pigment.

[0144] Lipophilic or hydrophobic treatment agents According to a particular embodiment of the present invention, the pigment may be coated in accordance with the present invention with at least one compound selected from silicone surface agents; fluorinated surface agents; fluorosilicone surface agents; metal soaps; N-acylamino acids or salts thereof; lecithin and its derivatives; isopropyl triisostearyl titanate; isostearyl sebacate; natural vegetable or animal waxes; polar synthetic waxes; fatty esters; phospholipids; and mixtures thereof.

[0145] Silicone Surface Agent According to a particular embodiment, the pigment may be fully or partially surface treated with a compound of silicone nature.

[0146] The silicone surface agent may be selected from organopolysiloxanes, silane derivatives, silicone-acrylate copolymers, silicone resins and mixtures thereof.

[0147] The term "organopolysiloxane compound" is understood to mean a compound having a structure containing alternating silicon and oxygen atoms and containing organic groups bonded to the silicon atoms.

[0148] Non-elastomeric organopolysiloxane In particular, non-elastomeric organopolysiloxanes may include polydimethylsiloxanes, polymethylhydrosiloxanes and polyalkoxydimethylsiloxanes.

[0149] An alkoxy group can be represented by an RO- group, where R represents methyl, ethyl, propyl, butyl or octyl, 2-phenylethyl, 2-phenylpropyl or 3,3,3-trifluoropropyl group, an aryl group such as phenyl, tolyl or xylyl, or a substituted aryl group such as phenylethyl.

[0150] One method for treating pigments with polymethylhydrosiloxane involves dispersing the pigment in an organic solvent and then adding a silicone compound. Heating the mixture creates a covalent bond between the silicone compound and the pigment surface.

[0151] According to a preferred embodiment, the silicone surface agent may be a non-elastomeric organopolysiloxane, in particular chosen from polydimethylsiloxanes.

[0152] Alkylsilanes and alkoxysilanes Silanes with alkoxy functionality are described in particular by Witucki in A Silane Primer, Chemistry and Applications of Alkoxysilanes, Journal of Coatings Technology, 65, 822, pages 57-60, 1993.

[0153] Alkoxysilanes such as alkyltriethoxysilanes and alkyltrimethoxysilanes sold under the references Milquet A-137® (OSI Specialties) and Prosil 9202® (PCR) can be used to coat the pigment.

[0154] The use of alkylpolysiloxanes with reactive end groups such as alkoxy, hydroxyl, halogen, amino or imino is described in JP 07-196946. They are also suitable for treating pigments.

[0155] Silicone-Acrylate Polymer Grafted silicone-acrylic polymers having a silicone backbone may be used, such as those described in U.S. Pat. Nos. 5,725,882, 5,209,924, 4,972,037, 4,981,903, 4,981,902, 5,468,477, as well as in U.S. Pat. No. 5,219,560 and EP 0,388,582.

[0156] Other silicone-acrylate polymers have in their structure the following formula (II): [Chemical formula 4] [ka] wherein the same or different G1 groups are hydrogen or C1-C 10 the same or different G2 groups are C1-C10 represents an alkylene group; G3 represents a polymer residue resulting from the (homo)polymerization of at least one ethylenically unsaturated anionic monomer; G4 represents a polymer residue resulting from the (homo)polymerization of at least one ethylenically unsaturated hydrophobic monomer; m and n are equal to 0 or 1; a is an integer ranging from 0 to 50; b is an integer which may be from 10 to 350, and c is an integer ranging from 0 to 50; with the proviso that one of the parameters a and c is other than 0. The silicone polymer may comprise units of:

[0157] Preferably, the unit of formula (I) above has the following characteristics: - the G1 group represents an alkyl group, preferably a methyl group; - n is non-zero and the G2 group represents a divalent C1-C3 group, preferably a propylene group; G3 represents a polymeric radical resulting from the (homo)polymerization of at least one monomer of the ethylenically unsaturated carboxylic acid type, preferably acrylic acid and / or methacrylic acid; - G4 is (C1~C 10 ) denotes a polymeric radical resulting from the (homo)polymerization of at least one monomer of the alkyl (meth)acrylate type, preferably of the isobutyl or methyl (meth)acrylate type; It indicates at least one of, and more preferentially also all of.

[0158] An example of a silicone polymer corresponding to formula (I) is in particular polydimethylsiloxane (PDMS) to which mixed polymer units of poly(meth)acrylic acid type and polymethyl(meth)acrylate type are grafted via thiopropylene type connecting links.

[0159] Another example of a silicone polymer corresponding to formula (I) is in particular polydimethylsiloxane (PDMS) to which polymer units of polyisobutyl(meth)acrylate type are grafted via thiopropylene type connecting links.

[0160] Silicone resin The silicone surface agent may be selected from silicone resins.

[0161] The term "resin" is understood to mean a three-dimensional structure.

[0162] Silicone resins may be soluble or swellable in silicone oil. These resins are crosslinked polyorganosiloxane polymers.

[0163] Silicone resin nomenclature is known by the designation "MDTQ," and resins are described according to the various siloxane monomer units they contain, with each of the letters "MDTQ" characterizing one type of unit.

[0164] The letter M represents the compound of the formula (CH3)3SiO 1 / 2 represents a monofunctional unit of the formula: where the silicon atom is linked to only one oxygen atom in the polymer containing this unit.

[0165] The letter D represents the difunctional unit (CH3)2SiO, in which a silicon atom is linked to two oxygen atoms. 2 / 2 means.

[0166] The letter T represents the formula (CH3)SiO 3 / 2 represents a trifunctional unit of

[0167] In the units M, D and T defined above, at least one of the methyl groups can be replaced by an R group other than a methyl group, such as a hydrocarbon (especially alkyl) group having 2 to 10 carbon atoms or a phenyl group, or alternatively a hydroxyl group.

[0168] Finally, the letter Q represents the tetrafunctional unit SiO 4 / 2 where the silicon atom is bonded to four oxygen atoms, which are themselves bonded to the rest of the polymer.

[0169] A variety of resins with different properties can be obtained from these different units, and the properties of these polymers vary depending on the type of monomer (or unit), the type and number of groups substituted, the chain length of the polymer, the degree of branching, and the size of the pendant chains.

[0170] Examples of these silicone resins include: - Formula [(CH3)3SiO 1 / 2 ]x(SiO 4 / 2 )y (MQ units), where x and y are integers ranging from 50 to 80; - Formula (CH3SiO 3 / 2 )x(T units), where x is greater than 100 and at least one of the methyl groups can be replaced by an R group as defined above; - polymethylsilsesquioxane, which is a polysilsesquioxane in which none of the methyl groups has been replaced by another group may be mentioned.

[0253] The invention is illustrated in more detail by the examples and figures presented below. Unless otherwise stated, amounts expressed are expressed as mass percentages. [Example]

[0254] Example A (invention) and Example B (non-invention) The following compositions were prepared:

[0255] [Table 1]

[0256] procedure The components of Phase A were weighed into a main beaker and placed in a VMI Turbotest EVO® homogenizer equipped with a deflocculating impeller at 1500 rpm for 15 minutes. The components of Phase B were weighed in and mixed until completely solubilized. The components of Phase C were weighed in and mixed until completely dispersed. Phases B and then C were then introduced into Phase A. The mixture was allowed to stir at 1500 rpm for 15 minutes.

[0257] The evaluations performed for Examples A and B were carried out at least 24 hours after preparation of the formulations.

[0258] Example 1: Tribology Sample preparation A 50 μm thick deposit was produced using a spreader on a support consisting of Lycra® fabric coated with a biocompatible 11 Shore silicone gel (SkinAbs, Prevent Transformation®) bonded to a 25 μm breathable polyurethane film. The deposit was stored at 25°C for 24 h to allow complete drying.

[0259] A sphere of dry deposit with a radius of 40 mm was cut to perform tribometer measurements.

[0260] Friction and Wear Dimensions The purpose of this in vitro dynamic friction test is to quantify the wear characteristics of a foundation.

[0261] To do so, deposits of foundation brought onto a normalized "Skinabs®" support, either dry or impregnated with an aggressor, were subjected to a friction test. The properties of "Skinabs®" are explained below.

[0262] The equipment used was in two parts: - a static top on which the normalizing "Skinabs®" support is placed, - by making circular movements, the lower part on which the normalizing "Skinabs®" containing the deposit of foundation, dry or impregnated with an attacking agent, is attached The tribometer was a CSM® pin-on-disk tribometer consisting of a tribometer that allows for the application of force normal to a plane and velocity of motion.

[0263] The friction that occurs during the rotational movement can cause wear phenomena depending on the resistance of the deposits. These result in a greater or lesser loss of material on the underlying Skinabs®.

[0264] The abrasion properties are quantified by observing the loss of material on the "Skinabs®" made up foundation before and after rubbing.

[0265] Deposits are prepared on "Skinabs®", a Lycra® fabric bonded to a 25 μm breathable polyurethane coating and coated with a biocompatible 11 Shore 00 silicone gel that promotes adhesion to the metal parts of the tribometer.

[0266] This "BioSkin" has two advantages: - It allows standardized application using a spreader. The homogeneity of the deposit obtained is entirely satisfactory for foundations. - 54mN.m -1 It has been estimated to be 43mN.m, similar to that of the skin. -1 surface tension.

[0267] The foundation was applied using a mechanical spreader at a standardized thickness of 50 μm by performing one pass. After drying in the open air for 24 h, when the deposit was judged to be completely dry, a 5 cm diameter disk of pre-made Skinabs® was cut out using a punch, taking care to avoid damage caused by cutting out the fixed formulation. This piece was then attached to the bottom of the tribometer.

[0268] Similarly, a piece of Skinabs® on top of the tribometer was cut into a 1.8 cm diameter disk, which was bonded onto a metal support of the same diameter in the form of a pressed cup.

[0269] The friction radius was set to 8 mm and the rotation speed to 36 rpm, which is equivalent to a linear velocity of 3 cm / s. The stopping criterion was one turn repeatable five times. The imposed load rating of 1 N allowed for differentiation of the area of ​​the foundation being tested while still having a low contact pressure representative of that in vivo.

[0270] Image acquisition is carried out by photography after each friction turn, and observation is carried out visually by comparing the state of the deposit before and after friction.

[0271] The sediment was evaluated after each pass and the degree of degradation (detachment, thinning, discoloration) was assessed throughout the analysis.

[0272] Observations and Results The behavior of formulations of DOWSIL FC 5002 IDD RESIN GUM®, Dow Corning, at different concentrations (0%, 10% active material) was analyzed.

[0273] [Table 2]

[0274] Composition A according to the invention was more resistant to abrasion than composition B outside the invention, which did not contain the silicone resin and the dimethiconol-type silicone-based copolymer.

[0275] Example 2: Rheological analysis Rheological measurements were performed with a forced stress rheometer (RheoStress 600®, Haake). Shear stress and velocity gradient measurements were performed using a cone sensor (C35 / 2° Ti L; 222-1871; 35 mm diameter, 2° angle) with a 0.105 mm gap and a measuring plate (MPC 35; 222-1549; 35 mm diameter, sandblasted). The temperature of the gap is controlled using an Eheim Pro 3600 / 2075020® hydraulic circulation pump and a Haake Universal Temperature Controller System® (UTC) 6001 temperature control system.

[0276] An anti-evaporation bell was placed above the plane of the cone and of the plate during the measurement.

[0277] The temperature of the gap was set at 25±0.5°C. A 120 s isotherm at this temperature was applied before each measurement. An upward oscillation curve with amplitude sweep was performed for 10 seconds at a frequency set at 1 Hz with 50 steps. -3 ~10 3 A stress ramp in the Pa range was imposed.

[0278] Observations and Results The rheological behavior of formulations A and B was analyzed. Measurement of the storage modulus G' and the loss or dissipation modulus G'' allowed the determination of the complex modulus G* and also the phase shift δ between stress and strain. These data were analyzed as a function of shear stress.

[0279] The behavior of the rheological curves indicates that they are materials that will simply flow if a high enough stress is applied to them.

[0280] The value of the complex modulus G* in the plateau preceding the break in the curve gives an idea of ​​the consistency of the product at rest.

[0281] The rheological data for the three formulations are listed in the table below.

[0282] [Table 3]

[0283] A lower complex modulus G* across the measurement range indicates a formulation that is more fluid, softer, and more homogeneous, regardless of the applied force. A more rapid change from the elastic to the viscous state during application means easier spreading on the skin.

[0284] Composition A according to the invention was more fluid, softer and more homogeneous than composition B outside the invention, which did not contain the silicone resin and the dimethiconol-type silicone-based copolymer.
