Description

[Technical Field]

[0001] The present invention relates to a fluid composition for makeuping and / or caring for keratinous substances, particularly skin, more specifically the face, comprising an oily phase containing at least one non-volatile synthetic ester oil, at least one porous spherical silica, non-porous composite silica, boron nitride, ultramarine blue pigment, and titanium dioxide pigment. The present invention also relates to a method for makeuping and / or caring for keratinous substances using the composition. [Background technology]

[0002] Consumers of fluid foundations aim to alter the appearance of their skin, specifically by making it more uniform and concealing its irregularities and imperfections. This camouflage is often achieved thanks to the coverage provided by white titanium dioxide (CI 77891) combined with black iron oxide (CI 77499), often seeking some lighter or darker shades. Most users seek a natural effect, as if their skin were not wearing any makeup, along with this correction. The challenge lies in finding the right balance between these parameters: too much coverage can result in a rough, uneven appearance, further emphasizing the skin's contours. Too little coverage can lead to disappointment regarding the quality of the product's correction.

[0003] Commercially available foundations rely on the contribution of titanium dioxide (white pigment) and iron black oxide to the covering power to hide defects. However, this can cause non-uniformity. This is because titanium dioxide has a certain tendency to enter skin wrinkles, fine lines, pores, and other undulations. This may become immediately visible to the naked eye on the macroscopic scale. Furthermore, if the total pigment content in the formulation remains unchanged, the lightest color tones (containing the most white pigment) face this problem more often than others. Therefore, like non-uniformity, the covering power is emphasized. In that case, this results in a "cakey" effect, such as a very aesthetically impaired powdery white coating that will adhere to the skin surface and further deteriorate throughout the day.

[0004] Finally, to correct facial irregularities, foundations tend to be very matte. This is because it naturally smooths out undulations. For darker color tones containing more black pigment, iron black oxide tends to enhance the matte property.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Therefore, there is still a need to create a new liquid formulation for making up and / or caring for keratin substances that can correct skin irregularities and defects, especially on the face, without the above-mentioned drawbacks, i.e., without showing the "cakey" effect, without emphasizing skin undulations such as wrinkles, fine lines, pores, etc., and without giving an overly matte finish, and by obtaining a homogeneous covering power, a natural finish, and the natural brightness and gloss of the skin (which appears as the "healthy facial appearance effect"). There is also a need to obtain a liquid formulation that can achieve these purposes by reducing the content of titanium dioxide without the need to use iron black oxide.

[0060] Porous spherical silica The composition according to the present invention contains porous spherical silica particles.

[0061] For the purposes of this invention, the term "porous particle" is understood to mean a particle having a structure that includes pores or gaps. The particle structure may be a sponge-like matrix type. The porosity of the particle is quantitatively characterized by its specific surface area.

[0062] The term "spherical silica" is understood to mean silica particles in a spherical or substantially spherical form that are insoluble in the medium of the composition according to the present invention, even at the melting point of the medium (about 100°C). The spherical particles of porous silica of the present invention may have an average circularity of at least 0.8, preferably at least 0.82. The spherical particles of porous silica of the present invention may have an average circularity e of 1 or less, preferably 0.99 or less, more preferably 0.98 or less, even more preferably 0.97 or less, even more preferably 0.96 or less, and most preferably 0.95 or less.

[0063] "Average circularity" can be determined by an image analysis method. Specifically, "average circularity" can be the arithmetic mean of circularity obtained by image analysis of scanning electron microscope (SEM) images of more than 2000 aerogel particles observed at 1000x magnification, using secondary electron detection with a scanning electron microscope (SEM).

[0064] The "circularity" of each silica particle is determined by the following equation: C = 4πS / L 2 (In the formula, C represents circularity, S represents the area of ​​the particle in the image (projected area), and L represents the length around the aerogel particle in the image (perimeter)). As the average circularity approaches 1, the shape of each particle becomes more spherical.

[0065] Porous spherical silica particles can be present in an amount of at least 1% by mass, preferably at least 1.8% by mass, and 10% by mass or less, more preferably 5% by mass or less, and most preferably 2% by mass or less, relative to the total mass of the composition.

[0066] The volume-average diameter of porous spherical silica particles is generally in the range of 0.1 μm (microns) to 40 μm (microns), preferably 1 μm to 20 μm.

[0067] The size of porous spherical silica particles can be measured by static light scattering using commercially available particle size distribution analyzers such as Malvern's MasterSizer 2000®. The data is processed based on Mie scattering theory. This theory is suitable for isotropic particles and, in the case of non-spherical particles, allows for the determination of the "effective" particle diameter. This theory is specifically described in the publication, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957, by Van de Hulst, H.C.

[0068] According to the present invention, porous spherical silica particles are 30 to 1000 m 2 / g, preferably 100-900m 2 It has a specific surface area of ​​ / g.

[0069] The specific surface area per unit mass can be determined by the Brunauer-Emmett-Teller (BET) nitrogen adsorption method, which is described in the Journal of the American Chemical Society, vol. 60, page 309, February 1938, and corresponds to the international standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles under consideration.

[0070] According to a preferred embodiment, the porous spherical silica particles are selected from the following: -Porous spherical particles of amorphous silica that have not undergone hydrophobic surface treatment; -Porous spherical particles of amorphous fumed silica; -Porous spherical particles of silica aerogel with a hydrophobic surface treatment; - A mixture of those.

[0071] The term "amorphous silica" is understood to refer to non-crystalline silica, in contrast to glassy silica, i.e., crystalline silica, where atoms do not respect any order at medium and long distances.

[0072] Untreated porous spherical amorphous silica As examples of porous spherical amorphous silica that has not undergone hydrophobic surface treatment, the following products can be used: Silica Beads SB-150(registered trademark), SB-300(registered trademark), or SB-700(registered trademark) from Miyoshi Chemicals, Ltd., preferably SB-300(registered trademark); Sunsphere(registered trademark) lineup from AGC Si-Tech Corporation, particularly Sunsphere H-51(registered trademark) or Sunsphere 12L(registered trademark), Sunsphere H-201(registered trademark), H-52 and H-53; Sunsil 130(registered trademark) from Sunjin; Spherica P-150(registered trademark) from Ikeda Bussan Co., Ltd.; Sylosphere(registered trademark) from Fuji Silicia Chemical Co., Ltd.; Silica Pearl(registered trademark) and Satinier(registered trademark) lineups from JGC Catalysts & Chemicals Corporation, more specifically Satinier M13(registered trademark) and Satinier M16® silica, Kobo's MSS-500® silica, more specifically MSS-500-20N®, and also Kobo's Silica Shells®.

[0073] According to a particular embodiment, the porous spherical particles of unhydrophobized amorphous silica according to the present invention have an oil absorption capacity measured at a wet point in the range of 0.25 to 3.5 g / g, preferably 0.5 to 1.5 g / g, and even better, 0.7 to 1.3 g / g.

[0074] The absorption capacity, measured at the wet point and denoted as Wp, corresponds to the amount of oil that needs to be added to 100g of particles to obtain a homogeneous paste. This is measured according to the "wet point" method, or the method for determining the oil absorption of powder as described in NF T standard 30-022. This corresponds to the amount of oil adsorbed onto the usable surface of the powder and / or absorbed by the powder, by measuring the wet point as described below: Place an amount of powder m = 2g on a glass plate, and then add oil (oleic acid) dropwise. After adding 4-5 drops of oil to the powder, mix with a spatula and continue adding oil until clumps of oil and powder are formed. From this point onward, add oil one drop at a time, and then polish the mixture with a spatula. Stop adding oil when a firm, smooth paste is obtained. This paste should be able to be spread on a glass plate without cracking or clumping. Then, write down the mass (g) of oil used.

[0075] Oil absorption capacity can also be measured in accordance with the JIS-K6217-4 standard.

[0076] Porous amorphous fumed silica According to certain embodiments, the porous spherical silica particles of the composition of the present invention are amorphous and fumed.

[0077] Fumed silica is subjected to hydrophobic surface treatment. In practice, the surface of silica can be chemically modified by a chemical reaction that reduces the number of silanol groups present on the silica surface. In particular, it is possible to replace silanol groups with hydrophobic groups, thereby obtaining hydrophobic silica.

[0078] Hydrophobic groups can be: -Trimethylsiloxyl group (which is obtained, in particular, by treating fumed silica in the presence of hexamethyldisilazane). Silica treated in this way has the INCI name "Silylated Silica". It is sold, for example, by Degussa under the reference name Aerosil R812, and by Cabot under the name Cab-O-Sil TS-530; -Dimethylsilyloxyl or polydimethylsiloxane groups (which are obtained, in particular, by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane). Silica treated in this way has the INCI name "dimethylsilylated silica" according to CTFA (8th edition, 2000). It is sold, for example, by Degussa under the reference names Aerosil R972 and Aerosil R974, and by Cabot under the reference names Cab-O-Sil TS-610 and Cab-O-Sil TS-720.

[0079] Spherical aerogel of hydrophobic silica According to a particular embodiment, the porous spherical silica is a spherical aerogel of hydrophobic silica.

[0080] Aerogels are materials with high porosity. Here, silica aerogel refers to a porous solid silica generally obtained by replacing the medium contained in moist silica gel with air by drying while maintaining the solid network structure of silica. Porosity represents the amount of air contained in the apparent volume of the material, expressed as a volume percentage. The spherical hydrophobic silica aerogel of the present invention can have a porosity of at least 60%, preferably at least 70%, and more preferably at least 80%.

[0081] The hydrophobic silica spherical aerogel of the present invention is characterized by the spherical shape of each particle. Thanks to this spherical shape, the hydrophobic silica aerogel makes it possible to obtain cosmetic compositions with excellent smoothness. The degree of sphericity of the hydrophobic silica aerogel can be determined by the average circularity.

[0082] In the spherical aerogel of hydrophobic silica of the present invention, the term "hydrophobic" means that the silica aerogel particles are difficult to disperse in water. More precisely, this term means that when 1 g of silica aerogel particles and 100 g of deionized water are added to a bottle, the bottle is stirred, or stirred for 10 seconds or more, and then the bottle is allowed to stand, the aerogel phase and the aqueous phase are completely separated. Therefore, in certain embodiments of the present invention, the spherical hydrophobic silica aerogel is not water-absorbing.

[0083] The spherical aerogel of hydrophobic silica that can be used in accordance with the present invention is preferably of the silylated silica type (INCI name: silylated silica). More preferably, the spherical hydrophobic silica aerogel may be one of those described in Japanese Patent Publication No. 2014-088307, Japanese Patent Publication No. 2014-218433, or Japanese Patent Publication No. 2018-177620.

[0084] Hydrophobicity can be achieved by reacting a hydrophobic agent with a silanol group present on the surface of silica, represented by the following equation: ≡Si-OH (wherein the symbol "≡" represents the remaining trivalent of the Si atom, and therefore the silanol group is represented by the following equation: (≡Si-O-) (4-n) SiR n (wherein n is an integer between 1 and 3; each R is independently a hydrocarbyl group; if n is 2 or greater, two or more Rs may be identical or different from one another) (the group is converted to the group represented by ).

[0085] The hydrophobic agent may be a silylation agent. Therefore, according to a preferred embodiment, in a spherical hydrophobic silica aerogel, silica particles can be surface-modified by silylation. Examples of silylation agents include treatment agents corresponding to one of the following formulas (1) to (3). [Chemical formula 3] R n SiX (4-n) (1) (In the formula, n represents an integer from 1 to 3; R represents a hydrocarbyl group; X represents a group that may leave the molecule by breaking its bond with a Si atom in a reaction with a compound having a hydroxyl group (i.e., an unstable group); each R may be different when n is 2 or greater; each X may be different when n is 2 or less). [Chemical formula 4] [ka] (In the formula, R 1 R represents an alkylene group; 2 and R 3 R independently represents a hydrocarbyl group; 4 and R 5 (Each represents either a hydrogen atom or a hydrocarbyl group.) [Chemical formula 5] [ka] (In the formula, R 6 and R 7 R independently represents a hydrocarbyl group; m represents an integer from 3 to 6; each R 6 is two or more R 6 They may be different if they exist; each R 7 is two or more R 7 (They may be different if they exist.)

[0086] In formula (1) above, R is a hydrocarbyl group, preferably a hydrocarbyl group having 1 to 10 carbon atoms, more preferably a hydrocarbyl group having 1 to 4 carbon atoms, and particularly preferably a methyl group.

[0087] Examples of unstable groups represented by X include halogen atoms such as chlorine and bromine; alkoxy groups such as methoxy and ethoxy groups; and groups represented by -NH-SiR3 (wherein the formula, the definition of R is the same as the definition of R in formula (1)).

[0088] Specific examples of hydrophobic agents represented by formula (1) above include: chlorotrimethylsilane, dichlorodimethylsilane, trichloromethylsilane, monomethyltrimethoxysilane, monomethyltriethoxysilane, and hexamethyldisilazane.

[0089] More preferably, and from the viewpoint of a favorable reaction, chlorotrimethylsilane, dichlorodimethylsilane, trichloromethylsilane and / or hexamethyldisilazane can be used.

[0090] The number of Si atoms bonded to silanol groups on the silica skeleton depends on the number of unstable groups X (4-n). For example, if n is 2, the following bond will occur: (≡Si-O-)2SiR 2 .

[0091] If n is 3, the following bond will occur: ≡Si-O-SiR3

[0092] In this way, the silanol group can be silylated, and therefore hydrophobicity can be achieved.

[0093] In equation (2) above, R 1 This can be an alkylene group, preferably an alkylene group having 2 to 8 carbon atoms, and particularly preferably an alkylene group having 2 to 3 carbon atoms.

[0094] In equation (2) above, R 2 and R 3 R is independently a hydrocarbyl group, and the same preferred group as for R in formula (1) can be formed. 4 represents a hydrogen atom or a hydrocarbyl group, and if it is a hydrocarbyl group, the same preferred group as for R in formula (1) can be formed. When silica gel is treated with the compound represented by formula (2) (cyclic silazane), the reaction with the silanol group results in the cleavage of the Si-N bond, and therefore the following bond is formed on the surface of the silica skeleton in the gel: (≡Si-O-)2SiR 2 R 3 .

[0095] In this way, the silanol group can also be silylated by the cyclic silazane of formula (2) above, and thus hydrophobization can be achieved.

[0096] Specific examples of cyclic silazanes represented by the above formula (3) include hexamethylcyclotrisilazane and octamethylcyclotetrasilazane.

[0097] In equation (3) above, R 6 and R 7 independently, a hydrocarbyl group can form the same preferred group as for R in formula (2). m represents an integer from 3 to 6. When silica gel is treated with the compound represented by formula (3) (cyclic siloxane), the following bonds are formed on the surface of the silica skeleton in the gel: (≡Si-O-)2SiR 6 R 7 .

[0098] In this way, the silanol group can also be silylated by the cyclic siloxane of formula (3) above, and thus hydrophobization can be achieved.

[0099] Specific examples of cyclic siloxanes represented by the above formula (3) include hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, and decamethylcyclopentasiloxane.

[0100] Spherical aerogels of hydrophobic silica can be prepared by generating a silica sol, converting the sol to a gel, maturing the gel, washing the matured gel, replacing the water in the washed gel with a solvent, and treating the gel with a hydrophobic agent to achieve silica hydrophobicity.

[0104] "Pore volume determined by the BJH method" refers to the pore volume obtained from pores with pore radii of 1 nm to 100 nm, obtained by analyzing the adsorption isotherm on the nitrogen adsorption side, which is obtained using the BJH method (Barrett, EP; Joyner, LG; Halenda, PP, J. Am. Chem. Soc. 73, 373 (1951)) in the same manner as described in "Specific surface area determined by the BET method" above. This was measured using the adsorption isotherm on the nitrogen adsorption side, which was obtained using the same method as described in "Specific surface area determined by the BET method" above. "Maximum pore radius determined by the BJT method" refers to the value of the pore radius that gives a peak in the pore distribution curve (volume distribution curve) plotted by taking the derivative of the cumulative pore volume on the logarithm of the pore radius obtained by analyzing the adsorption isotherm on the nitrogen adsorption side, which is obtained using the BJH method, and plotting the pore radius on the horizontal axis.

[0105] The hydrophobic silica spherical aerogel can have an average size of at least 0.5 μm, preferably at least 1 μm, more preferably at least 2 μm, and an average size of 30 μm or less, preferably 20 μm or less, more preferably 15 μm or less, as determined by image analysis methods.

[0106] In this specification, the "average particle size" can be measured by an image analysis method. More precisely, the "average particle size" value is the arithmetic mean of the equivalent circle diameters that can be obtained by image analysis of scanning electron microscope (SEM) images of more than 2000 aerogel particles observed at 1000x magnification, for example, by detecting secondary electrons using a scanning electron microscope (SEM). The "equivalent circle diameter" of each aerogel particle is the diameter of a circle having a surface area equal to the surface area (projected surface area) of the aerogel particle in the image.

[0112] Non-porous silica composite particles The composition according to the present invention comprises at least non-porous silica composite particles.

[0113] In the context of the present invention, the term "silica composite particles" means silica particles that contain at least one functional compound, preferably at least one metal oxide. Therefore, preferably, composite silica particles can refer to "silica particles containing at least one metal oxide." Preferably, the metal oxide is dispersed within the silica particles.

[0114] The metal oxide can preferably be selected from titanium dioxide, zinc oxide, iron oxide, and zirconium oxide, or mixtures thereof, more specifically titanium dioxide (TiO2) and zinc oxide (ZnO), and mixtures thereof. Titanium dioxide can be used, in particular preference.

[0115] Nonporous silica composite particles can have an average size determined by an image analysis method of at least 0.1 μm, preferably at least 0.5 μm, and more preferably at least 1 μm, and an average size determined by an image analysis method of 50 μm or less, preferably 20 μm or less, and more preferably 10 μm or less.

[0116] The "average particle size" can be determined by following these steps: Particle size is measured using SEM images, and the average particle size is calculated.

[0119] Non-porous silica composite particles can be surface-treated to become hydrophobic. For example, composite silica particles can be surface-treated with alkylsilanes.

[0125] Hexagonal boron nitride (h-BN) has a "hexagonal sheet" structure formed by ABAB-type stacking of BN planes, where BN planes are completely overlapped from one plane to another, due to the difference in chemical properties of elements B and N.

[0126] According to a particular embodiment of the present invention, boron nitride particles having a plate-like shape and a hexagonal crystal structure (h-BN) are used.

[0127] Preferably, the boron nitride particles have an oxygen content in the range of 0.05% to 3% by mass, more preferably 0.1% to 2.5% by mass, relative to the total mass of the particles.

[0128] Preferably, the boron nitride particles have an average particle size in the range of 0.1 to 25 μm, and more preferably 0.3 to 15 μm.

[0129] Particle size is measured according to a laser scattering distribution method using an instrument such as Nikkiso Co., Ltd.'s Microtrac instrument or Malvern's 3042407 16 Mastersizer instrument, specifically by measuring the D

[10] , D

[50] , and D

[90] values. D

[10] represents the maximum size exhibited by 10 volume percent of particles. D

[50] represents the maximum size exhibited by 50 volume percent of particles. D

[0132] The mass ratio of boron nitride to titanium dioxide is in the range of 0.3 to 1.

[0133] When the mass ratio of boron nitride to titanium dioxide is less than 0.3, or even equal to 0, a significant increase in coverage is observed, resulting in a rougher appearance of the skin and further emphasizing its contours.

[0134] When the mass ratio of boron nitride to titanium dioxide exceeds 1.0, insufficient coverage is observed, making it impossible to conceal skin imperfections.

[0135] Preferably, the composition according to the present invention contains boron nitride in an amount ranging from 2% to 10% by mass, more preferably 3% to 9% by mass, and more specifically 4% to 8% by mass, based on the total mass of the composition.

[0142] For the purposes of the present invention, "coating" of a pigment according to the present invention generally refers to a whole or partial surface treatment of the pigment with a surface agent that is absorbed, adsorbed, or grafted onto the pigment.

[0143] Surface-treated pigments can be prepared according to surface treatment techniques of chemical, electrical, mechanochemical, or mechanical properties that are well known to those skilled in the art. Commercially available products can also be used.

[0144] Surface agents can be absorbed, adsorbed, or grafted onto pigments by evaporation of the solvent, chemical reactions, and the formation of covalent bonds.

[0145] According to one modified form, the surface treatment includes coating with a pigment.

[0146] The coating may amount to 0.1% to 20% by mass, and particularly 0.5% to 5% by mass, relative to the total mass of the pigment being coated.

[0147] The coating can be produced, for example, by adsorption of a liquid surface agent onto the surface of solid particles, by simply mixing the particles and the surface agent while stirring and optionally while heating, prior to incorporating the particles into other components of the makeup or care composition.

[0148] The coating can be produced, for example, by a chemical reaction between a surface agent and the surface of solid pigment particles, and by the formation of covalent bonds between the surface agent and the particles. This method is described in particular in U.S. Patent No. 4,578,266.

[0149] 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 adheres to the surface of the pigment.

[0150] If the pigment includes an oil-lipid or hydrophobic coating, it is preferable that this is present in the fatty phase of the composition according to the present invention.

[0151] According to certain embodiments of the present invention, the ultramarine blue pigment can be coated in accordance with the present invention with at least one compound selected from silicone surface agents; fluorine-based surface agents; fluorosilicone-based surface agents; metal soaps; N-acyl amino acids or salts thereof; lecithin and its derivatives; isopropyltriisostearyl titanate; isostearyl sebacate; natural plant or animal waxes; polar synthetic waxes; fatty acid esters; phospholipids; and mixtures thereof.

[0154] Preferably, the composition according to the present invention contains an amount of ultramarine blue pigment ranging from 0.5% to 5% by mass, more preferably 0.5% to 2% by mass, based on the total mass of the composition.

[0155] Titanium dioxide pigment The composition according to the present invention comprises at least one pigment (CI 77891) of the form of free titanium dioxide.

[0157] According to a particular embodiment of the present invention, the pigment has a size characterized by D

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

[0158] This size is measured by static light scattering using Malvern's commercially available MasterSizer 3000 particle size analyzer, which allows for the determination of particle size distributions across a wide range, potentially from 0.01 μm to 1000 μm. The data is processed based on standard Mie scattering theory, which is best suited to particle size distributions in the submicron to several micron range and allows for the determination of "effective" particle diameters. This theory is specifically described in the publication, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957, by Van de Hulst, HC. D

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

[0159] Preferably, the composition contains at least 1% by mass, more preferably 2% to 10% by mass, and more specifically 3% to 7% by mass, of titanium dioxide pigment based on the total mass of the composition.

[0177] For the purposes of this invention, the term "stabilized" means that there is no influence of color fluctuations due to the viewing angle or in response to temperature changes.

[0178] For example, this material can be selected from metallic hues, goniochromatic colorants, diffraction pigments, thermochromic agents, optical whitening agents, and also fibers, particularly particles having interference fibers. Needless to say, these various materials can be combined to produce two effects, and even novel effects according to the present invention, simultaneously.

[0179] The metallic-colored particles that can be used in the present invention are specifically selected from the following: - Particles of at least one metal and / or at least one metal derivative; Particles comprising a single or multiple organic or inorganic substrate, and mixtures thereof, at least partially coated with at least one layer having a metallic hue containing at least one metal and / or at least one metal derivative.

[0180] Among the metals that can be present in the particles, examples include Ag, Au, Cu, Al, Ni, Sn, Mg, Cr, Mo, Ti, Zr, Pt, Va, Rb, W, Zn, Ge, Te, Se, and mixtures or alloys thereof. Ag, Au, Cu, Al, Zn, Ni, Mo, Cr, and mixtures or alloys thereof (e.g., bronze and brass) are preferred metals.

[0181] The term "metal derivative" refers to compounds derived from metals, particularly oxides, fluorides, chlorides, and sulfides.

[0182] Examples of these particles that can be cited include aluminum particles, such as those sold by Silberline under the name Starbrite 1200 EAC® and by Eckart under the name Metalure®.

[0183] Examples include copper metal powders or alloy mixtures such as reference name 2844 (registered trademark) sold by Radium Bronze, metal pigments such as aluminum or bronze, such as those sold by Eckart under the name Rotosafe 700 (registered trademark), metal alloy particles such as silica-coated aluminum particles sold by Eckart under the name Visionaire Bright Silver (registered trademark), and silica-coated bronze (copper and zinc alloy) powder sold by Eckart under the name Bright Natural Gold (registered trademark); and in particular, pearlescent agents having a white hue, consisting of synthetic mica coated with titanium dioxide and tin oxide, such as the INCI name: Synthetic Fluorphlogopite (and) Titanium Dioxide (and) Tin Oxide, such as the product sold by Eckart under the trade name Syncrystal Silk Silver (registered trademark).

[0184] These may also be particles containing a glass substrate, such as those sold by Nippon Sheet Glass Co., Ltd. under the name Microglass Metashine®.

[0185] The goniochromatic colorant can be selected from, for example, multilayer interference structures and liquid crystal colorants.

[0186] Examples of symmetrical multilayer interference structures that can be used in compositions prepared according to the present invention include, for example, the following structures: Al / SiO2 / Al / SiO2 / Al (pigments having this structure are sold by Dupont De Nemours); Cr / MgF2 / Al / MgF2 / Cr (pigments having this structure are sold by Flex under the name Chromaflair®); MoS2 / SiO2 / Al / SiO2 / MoS2; Fe2O3 / SiO2 / Al / SiO2 / Fe2O3, and Fe2O3 / SiO2 / Fe2O3 / SiO2 / Fe2O3 (pigments having these structures are sold by BASF under the name Sicopearl®); MoS2 / 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 having these structures are sold by Merck (Darmstadt) under the name Xirona®). For example, these pigments may be silica / titanium dioxide / tin oxide structured pigments sold by Merck under the name Xirona Magic®, silica / brown iron oxide structured pigments sold by Merck under the name Xirona Indian Summer®, and silica / titanium dioxide / mica / tin oxide structured pigments sold by Merck under the name Xirona Caribbean Blue®. Shiseido Co., Ltd.'s Infinite Colors® pigments can also be mentioned. Different effects can be obtained depending on the thickness and properties of the various layers. For example, when using the Fe2O3 / SiO2 / Al / SiO2 / Fe2O3 structure, the color changes from greenish-gold to reddish-gray for the SiO2 layer at 320-350 nm; from red to gold for the SiO2 layer at 380-400 nm; from purple to green for the SiO2 layer at 410-420 nm; and from copper to red for the Si2 layer at 430-440 nm.

[0187] An example of a pigment with a multilayer polymer structure is the one sold by 3M under the name Color Glitter®.

[0188] Examples of liquid crystal goniochromatic particles that can be used include those sold by Chenix and those sold by Wacker under the name Helicone® HC.

[0189] Additional pigments that can be used in accordance with the present invention include organic pigments.

[0190] The term "organic pigment" is understood to mean any pigment that meets the definition in the chapter on organic pigments in Ullmann's Encyclopedia. Organic pigments can be selected from, in particular, nitroso, nitro, azo, xanthene, quinoline, anthraquinone, phthalocyanine, metal complex type, isoindolinone, isoindoline, quinacridone, perinone, perylene, diketopyrrolopyrrole, thioindigo, dioxazine, triphenylmethane, or quinophthalone compounds.

[0192] These additional pigments may also be in the form of composite pigments as described in European Patent No. 1184426. Specifically, these composite pigments may consist of particles comprising an inorganic core coated at least partially with an organic pigment and at least one binder for fixing the organic pigment to the core.

[0193] Additional pigments can also be lakes. The term "lake" is understood to mean an insoluble dye adsorbed onto insoluble particles, and the resulting aggregate remains insoluble during use.

[0194] The inorganic substrates on which the dye is adsorbed include, for example, alumina, silica, sodium calcium borosilicate or aluminum calcium borosilicate, and aluminum.

[0195] Among organic dyes, cochineal carmine is one example. Mention may also be made of products known by the following names: D&C Red 21 (CI 45 380), D&C Orange 5 (CI 45 370), D&C Red 27 (CI 45 410), D&C Orange 10 (CI 45 425), D&C Red 3 (CI 45 430), D&C Red 4 (CI 15). 510), D&C Red 33(CI 17 200), D&C Yellow 5(CI 19 140), D&C Yellow 6(CI 15 985), D&C Green(CI 61 570), D&C Yellow 1 O(CI 77 002), D&C Green 3(CI 42 053), D&C Blue 1(CI 42 090).

[0196] An example of a rake that can be mentioned is a product known as D&C Red 7 (CI 15 850:1). That is the case.

[0197] In one particularly preferred embodiment, for the purpose of providing light reflection without loss of coverage, the composition of the present invention comprises at least one pearlescent agent having a white hue, specifically consisting of synthetic mica coated with titanium dioxide and tin oxide (INCI name: Synthetic Fluorphlogopite (and) Titanium Dioxide (and) Tin Oxide), such as a product sold by Eckart under the trade name Syncrystal Silk Silver.

[0198] Water-in-oil emulsion In a particular form, the composition is in the form of a water-in-oil emulsion.

[0199] The aqueous phase of the composition according to the present invention comprises at least one aqueous medium, namely water and optionally a water-soluble solvent.

[0200] In this invention, the term "water-soluble solvent" refers to a compound that is liquid at ambient temperature and miscible with water (miscibility with water exceeds 50% by mass at 25°C and atmospheric pressure).

[0201] The water-soluble solvents that can be used in the compositions of the present invention may also be volatile.

[0202] Among the water-soluble solvents that can be used in the compositions according to the present invention, particularly noteworthy are alcohols, for example, lower monoalcohols containing 1 to 5 carbon atoms, such as ethanol and isopropanol; glycols containing 2 to 8 carbon atoms, such as ethylene glycol, propylene glycol, 1,3-butylene glycol, and dipropylene glycol; C3 and C4 ketones; and C2 to C4 aldehydes.

[0203] According to a modified version of another embodiment, the aqueous phase of the composition according to the present invention may contain at least one C2-C32 polyol.

[0204] For the purposes of this invention, the term "polyol" should be understood to mean any organic molecule containing at least two free hydroxyl groups. Preferably, the polyol according to the present invention exists in liquid form at ambient temperature.

[0205] Polyols suitable for use in the present invention may be linear, branched, or cyclic saturated or unsaturated alkyl compounds having at least two -OH groups, more specifically at least three -OH groups, and more specifically at least four -OH groups on the alkyl chain. Polyols conveniently suited for formulation of compositions according to the present invention are those particularly containing 2 to 32 carbon atoms, preferably 3 to 16 carbon atoms. Conveniently, the polyol can be selected from, for example, ethylene glycol, pentaerythritol, trimethylolpropane, propylene glycol, 1,3-propanediol, butylene glycol, isoprene glycol, pentylene glycol, hexylene glycol, glycerol (glycerin), polyglycerol, such as glycerol oligomers, such as diglycerol, and polyethylene glycol, as well as mixtures thereof. According to certain embodiments, compositions of the present invention may contain at least glycerol.

[0206] The aqueous phase (water and optionally a water-miscible solvent) may be present in the composition in an amount of at least 10% by mass, more preferably at least 25% by mass, and 50% by mass or less, preferably 45% by mass or less, and more preferably 35% by mass or less, based on the total mass of the composition.

[0207] The water-in-oil emulsion according to the present invention generally contains one or more emulsifying surfactants, preferably nonionic.

[0208] The emulsifier is present in the composition in an amount ranging from 0.5% to 10% by mass, more preferably 2% to 5% by mass, relative to the total mass of the composition.

[0209] Within the scope of this invention, the term “emulsifying surfactant” is understood to mean an amphiphilic surfactant, i.e., one exhibiting two parts of different polarities. Generally, one part is lipophilic (soluble or dispersible in the oily phase), and the other is hydrophilic (soluble or dispersible in water). Emulsifying surfactants are characterized by their HLB (hydrophilic-lipophilic balance) value, which is the ratio of the hydrophilic to lipophilic parts in the molecule. The term “HLB” is well known to those skilled in the art and is described, for example, in “The HLB System: A Time-Saving Guide to Emulsifier Selection” (published by ICI Americas Inc.; 1984). For emulsifying surfactants, the HLB is generally in the range of 3 to 8 for the preparation of W / O emulsions. The HLB of surfactants used according to this invention can be determined by the Griffin method or the Davies method.

[0210] Examples of W / O emulsifying surfactants include alkyl esters or ethers of sorbitan, glycerol, polyol, glycerol, or sugar; silicone surfactants, such as dimethicone copolyols, for example, products with the INCI name PEG-10 dimethicone sold by Shin-Etsu Chemical Co., Ltd. under the trademark KF-6017 (registered trademark); products with the INCI name dimethicone (and) PEG / PPG-18 / 18 dimethicone sold by Shin-Etsu Chemical Co., Ltd. under the trademark X-22-6711D (registered trademark); products with the INCI name BIS-PEG / PPG-14 / 14 dimethicone (and) dimethicone, such as products sold by Evonik Goldschmidt under the name Abil EM 97 S (registered trademark); mixtures of cyclomethicone and dimethicone copolyol sold by Dow Corning under the name DC 5225 C (registered trademark); and Dow Corning Examples include alkyl dimethicone copolyols such as lauryl methicone copolyol sold under the name 5200 Formulation Aid; cetyl dimethicone copolyols such as CETYL PEG / PPG-10 / 1 DIMETHICONE, for example, the product sold by Evonik Goldschmidt under the name Abil EM 90 (registered trademark), and a mixture of cetyl dimethicone copolyol sold by Evonik Goldschmidt under the name Abil WE 09 (registered trademark), polyglyceryl isostearate (4 mol), and hexyl laurate. One or more coemulsifiers, which can be conveniently selected from the group including polyol alkyl esters, can also be added thereto.

[0211] Non-silicone emulsifying surfactants, specifically alkyl esters or ethers of sorbitan, glycerol, polyol, or sugar, can also be mentioned.

[0212] Examples of polyol alkyl esters include polyethylene glycol esters, such as PEG-30 dipolyhydroxystearate, for example, the product sold by Croda under the name Cithrol DPHS-SO-(MV) (registered trademark).

[0213] Examples of glycerol and / or sorbitan esters include polyglyceryl isostearate (INCI name: polyglyceryl-4 isostearate), for example, the product sold by Evonik Goldschmidt under the name Isolan GI 34®; sorbitan isostearate, for example, the product sold by ICI under the name Arlacel 987®; sorbitan glyceryl isostearate, for example, the product sold by ICI under the name Arlacel 986®; a mixture of isostearic acid, polyhydroxystearic acid, and sebacic acid with polyglycerin-4 (INCI name: (diisostearate / polyhydroxystearic acid / sebacic acid) polyglyceryl-4), for example, the product sold by Evonik under the name Isolan GPS®; and mixtures thereof.

[0214] According to a particular embodiment of the present invention, the emulsifying surfactant can be selected from emulsifying silicone elastomers.

[0215] The term "silicone elastomer" is understood to refer to a flexible, deformable organopolysiloxane having viscoelastic properties, particularly a spongy density or flexible spherical shape. Its modulus of elasticity is such that the material withstands deformation while having limited stretch and shrinkage. The material has the ability to return to its original shape after being stretched.

[0216] Emulsifying silicone elastomers can be selected from polyoxyalkylene-based silicone elastomers, polyglycerol-based silicone elastomers, and mixtures thereof.

[0217] Polyoxyalkylene-containing silicone elastomer Polyoxyalkylene-modified silicone elastomers are crosslinked organopolysiloxanes that can be obtained by a crosslinking addition reaction between a diorganopolysiloxane containing at least one hydrogen atom bonded to silicon and a polyoxyalkylene containing at least two ethylenically unsaturated groups.

[0218] Preferably, the polyoxyalkylene-crosslinked organopolysiloxane is obtained by a crosslinking addition reaction of (A1) a diorganopolysiloxane, each containing at least two silicon-bonded hydrogens, and (B1) a polyoxyalkylene containing at least two ethylenically unsaturated groups, particularly in the presence of (C1) a platinum catalyst, as described in U.S. Patent No. 5,236,986 and U.S. Patent No. 5,412,004.

[0219] In particular, organopolysiloxanes can be obtained by the reaction of a polyoxyalkylene (especially polyoxyethylene and / or polyoxypropylene) having a dimethylvinylsiloxy terminus with a methylhydropolysiloxane having a trimethylsiloxy terminus, in the presence of a platinum catalyst.

[0220] The organic groups bonded to the silicon atom of compound (A1) may be alkyl groups having 1 to 18 carbon atoms, such as methyl, ethyl, propyl, butyl, octyl, decyl, dodecyl (or lauryl), myristyl, cetyl, or stearyl; substituted alkyl groups, such as 2-phenylethyl, 2-phenylpropyl, or 3,3,3-trifluoropropyl; aryl groups, such as phenyl, tolyl, or xylyl; substituted aryl groups, such as phenylethyl; and substituted monovalent hydrocarbon groups, such as epoxy groups, carboxylate ester groups, or mercapto groups.

[0221] Therefore, compound (A1) can be selected from methylhydropolysiloxane having a trimethylsiloxy terminus, dimethylsiloxane / methylhydrosiloxane copolymer having a trimethylsiloxy terminus, dimethylsiloxane / methylhydrosiloxane cyclic copolymer, and dimethylsiloxane / methylhydrosiloxane / laurylmethylsiloxane copolymer having a trimethylsiloxy terminus.

[0222] Compound (C1) is a catalyst for the crosslinking reaction, and specifically includes chloroplatinic acid, chloroplatinic acid-olefin complex, chloroplatinic acid-alkenylsiloxane complex, chloroplatinic acid-diketone complex, platinum black, and supported platinum.

[0223] Conveniently, polyoxyalkylene silicone elastomers can be formed by reacting a divinyl compound, particularly a polyoxyalkylene containing at least two vinyl groups, with the Si-H bond of a polysiloxane.

[0224] The polyoxyalkylene silicone elastomer according to the present invention is preferably mixed with at least one hydrocarbon oil and / or one silicone oil to form a gel. In these gels, the polyoxyalkylene elastomer may be in the form of non-spherical particles.

[0225] Polyoxyalkylene elastomers are described in particular in U.S. Patent No. 5,236,986, U.S. Patent No. 5,412,004, U.S. Patent No. 5,837,793, and U.S. Patent No. 5,811,487.

[0228] These are sold by Dow Corning, in particular, under the name Dow Corning 9011 Silicone Elastomer Blend®; INCI name: Cyclopentasiloxane and PEG-12 Dimethicone Crosspolymer.

[0229] Regarding compounds containing the INCI name (PEG-12 dimethicone / PPG-20) crosspolymer, we can also mention the product sold by Dow Corning under the name Dow Corning EL-7040 Hydro Elastomer Blend® (registered trademark).

[0230] Polyglycerol-containing silicone elastomer Polyglycerol-modified silicone elastomers are elastomeric, crosslinked organopolysiloxanes that can be obtained by a crosslinking addition reaction between a diorganopolysiloxane containing at least one hydrogen atom bonded to silicon and a polyglycerol-modified compound containing an ethylenically unsaturated group, particularly in the presence of a platinum catalyst.

[0231] Preferably, the elastomeric crosslinked organopolysiloxane is obtained by a crosslinking addition reaction of (A) a diorganopolysiloxane containing at least two hydrogen atoms, each bonded to silicon, and (B) a glycerolated compound containing at least two ethylenically unsaturated groups, particularly in the presence of (C) a platinum catalyst.

[0232] In particular, organopolysiloxanes can be obtained by the reaction of a polyglycerol-containing compound having a dimethylvinylsiloxy terminus with a methylhydropolysiloxane having a trimethylsiloxy terminus, in the presence of a platinum catalyst.

Preferably, the organic group is selected from methyl, phenyl, and lauryl groups.

[0238] Therefore, compound (A) can be selected from methylhydropolysiloxane having a trimethylsiloxy terminus, dimethylsiloxane / methylhydrosiloxane copolymer having a trimethylsiloxy terminus, dimethylsiloxane / methylhydrosiloxane cyclic copolymer, and dimethylsiloxane / methylhydrosiloxane / laurylmethylsiloxane copolymer having a trimethylsiloxy terminus.

[0239] Compound (B) may be a polyglycerolated compound corresponding to the following formula: [Chemical formula 6] C m H 2m-1 -O-[Gly] n -C m H 2m-1 (wherein m is an integer in the range of 2 to 6, n is an integer in the range of 2 to 200, preferably in the range of 2 to 100, preferably in the range of 2 to 50, n is preferably in the range of 2 to 20, preferably in the range of 2 to 10, preferably in the range of 2 to 5, and especially equal to 3; Gly represents the following: -CH2-CH(OH)-CH2-O- or -CH2-CH(CH2OH)-O-).
