Description

[Technical Field]

[0001] This invention relates to a thin-film powder cosmetic. [Background technology]

[0002] Solid powder cosmetics such as foundation, eye shadow, and eyebrow powder are usually manufactured by filling containers such as metal trays with powder and then compressing and molding them. On the other hand, for purposes such as samples or portable use, there is a form in which a powder-containing cosmetic base is solidified onto a sheet-like medium (substrate) such as plastic film or cardboard to form a thin film of cosmetic.

[0003] In this form, the powder-containing cosmetic base is dispersed in a solvent to form a slurry, and this slurry is then applied to a sheet-like medium such as paper to form a film. Therefore, the ability to form a film on the sheet-like medium is an important quality item.

[0004] For example, Patent Document 1 describes a method of applying a coating solution, in which a powder cosmetic base containing a nonionic surfactant and powder components is dispersed in purified water, to a paper substrate to produce a paper-like cosmetic. According to this paper-like cosmetic, the cosmetic is uniformly applied to the paper substrate. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 6-206807 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] As described above, it is necessary for the cosmetic to properly adhere (fix) to a medium such as paper substrate to form a strong film. Cosmetics are often subjected to impact during transportation, and if the film is not strong, the cosmetic may partially detach from the medium when subjected to impact.

[0007] On the other hand, with solid powder cosmetics, the cosmetics are applied to the user's skin using fingers or an applicator (for example, a mat), and it is important that the amount of cosmetics applied is appropriate (that the appropriate amount of cosmetics adheres to the fingers or applicator).

[0008] However, the more the adhesion to the medium is increased and the stronger the resulting thin film becomes, the more difficult it is for the cosmetic to remove from the medium. In other words, there is a trade-off between adhesion to the medium and removal of the cosmetic, and it is difficult to achieve both simultaneously.

[0009] Furthermore, powder cosmetics contain a large amount of powder, and especially when the powder is dispersed in a solvent to form a thin film, aggregates of the powder tend to form. These aggregates of powder are difficult to break down when spread on the skin and do not form a makeup film well, which can reduce the effectiveness of the makeup.

[0010] Therefore, the present invention aims to provide a thin-film powder cosmetic that is less likely to detach from the medium even when subjected to impact, has good traction, and has few aggregates. [Means for solving the problem]

[0012] According to the present invention, the thin film powder cosmetic composition is less likely to fall off the medium even when subjected to impact, produces less chipping and dust, adheres to the applicator and fingers in an appropriate amount (good cosmetic transfer), and contains fewer aggregates in the cosmetic composition. [Modes for carrying out the invention]

[0013] Embodiments of the present invention will be described below. However, the present invention is not limited to the embodiments described below. In this specification, "X~Y" indicating a range includes X and Y, and means "X or more and Y or less". Unless otherwise specified, operations and measurements of physical properties, etc., are performed under room temperature (20~25℃) / relative humidity 45~55%RH conditions.

[0014] The first embodiment of the present invention comprises the following components (A) to (D); (A) A powder obtained by surface-treating a plate-shaped powder with amino-modified silicone, (B) A powder obtained by surface-treating plate-shaped powder with silicone (excluding component (A)), (C) Dextrin fatty acid ester, (D) Non-volatile oil in liquid form at 25°C It is a thin-film powder cosmetic containing [the specified ingredient].

[0015] The thin film powder cosmetic composition with the above configuration is less likely to fall off the medium even when subjected to impact (high adhesion to the medium), has good adhesion to the medium, and is a thin film powder cosmetic composition with few aggregates.

[0016] The mechanism by which the thin film powder cosmetic composition with the above composition produces the above-mentioned effects is presumed to be as follows.

[0017] In thin-film powder cosmetics, a cosmetic base dispersed in a solvent is applied to a medium, causing the base to adhere to the (sheet-like) medium. As the solvent evaporates, the thin-film cosmetic is supported on the medium. In cosmetics, plate-shaped powders are commonly used because they align uniformly on the skin during application, making them easy to fit and providing a smooth feel. However, due to their shape, plate-shaped powders tend to overlap in layers when held on a medium, making them prone to clumping and peeling off when subjected to impact. As a result of various studies conducted by the inventors, it was found that combining a powder obtained by treating plate-shaped powder with amino-modified silicone, as in component (A), with component (C), a dextrin fatty acid ester, results in good adhesion to the medium. This is thought to be because components (A) and (C) readily integrate, forming a strong cosmetic film on the medium, allowing the cosmetic to remain on the medium even when subjected to impact. In this case, it is thought that combining component (B) mitigates the problem of excessive bonding between component (A) and component (C), which could worsen the texture of the cosmetic or lead to the formation of aggregates. Furthermore, component (D) improves the dispersibility of components (A), (B), and (C), allowing each component to effectively exert its effects. Therefore, it is thought that the inclusion of component (D) improves all of the effects.

[0018] In this invention, the powdered cosmetic composition is a cosmetic composition mainly composed of powder (powder, particles). Here, the main component refers to a composition that makes up 50% by mass or more, preferably 60% by mass or more, and more preferably 70% by mass or more. That is, in this embodiment, the total amount of powder (including surface-treated powder) including component (A), component (B), and other powders is 50% by mass or more of the cosmetic composition (the upper limit is the mass %) of the total cosmetic composition minus the content of component (C) and component (D), preferably 60% by mass or more, more preferably 70% by mass or more, even more preferably 70-99% by mass, and even more preferably 70-85% by mass.

[0019] In thin-film powder cosmetics, "thin-film" refers to a film formed in a solid state with a substantially uniform thickness on a medium. In this case, the thickness of the cosmetic is, for example, 2 mm or less, may be 1 mm or less, preferably 800 μm or less, and may be between 50 and 500 μm.

[0020] Hereafter, thin-film powder cosmetics will also be referred to simply as cosmetics.

[0021] Each component constituting this embodiment will be described below.

[0022] (Component (A): A powder formed by surface-treating plate-shaped powder with amino-modified silicone.) Component (A) is a powder obtained by surface-treating a plate-shaped powder with amino-modified silicone.

[0023] Here, plate-like powder refers to powder in which the average particle diameter is larger than the average thickness, and specifically, an aspect ratio of 3 or more is preferred. The aspect ratio is calculated by the ratio of the average particle diameter to the average particle thickness, and is defined as aspect ratio = (average particle diameter / average thickness). The average particle diameter can be calculated from image data obtained by measuring 100 particles using a desktop scanning electron microscope (proX PREMIUM, manufactured by JUSCO International) at an acceleration voltage of 5 to 15 kV and a magnification of 1000 to 25000 times. The particle diameter of plate-like powder is the major axis (maximum diameter). The thickness is determined by measuring the difference from a reference plane using an atomic force microscope and taking the arithmetic mean as the average thickness. The planar shape of plate-like powder can be rectangular, circular, irregular, etc. In addition to plate-like shapes, plate-like powder also includes powders with shapes referred to as flake-like, scale-like, etc.

[0024] The plate-like powder structure allows for good shedding of the cosmetic from the medium and provides a smooth feel when applied to the skin. On the other hand, when plate-like powder is incorporated, the cosmetic tends to detach from the medium in clumps when subjected to impact. However, with the configuration of this embodiment, it is possible to improve adhesion to the medium while maintaining the smooth feel provided by the inclusion of plate-like powder.

[0025] Examples of plate-like powders include, specifically, mica, sericite, talc, plate-like barium sulfate, plate-like calcium sulfate, synthetic fluorophlogopite, borosilicate (Ca / Al), borosilicate (Ca / Na), (PET / polymethyl methacrylate) laminate, inorganic plate-like powders such as (fluoride / hydroxylated / oxidized) / (Mg / K / silicon), and composite powders obtained by coating these plate-like powders (titanium dioxide coated mica, iron oxide coated mica, titanium dioxide coated synthetic fluorphlogopite, titanium dioxide coated borosilicate (Ca / Al), titanium dioxide coated borosilicate (Ca / Na), silicon dioxide / titanium dioxide coated mica, silicon dioxide / titanium dioxide coated borosilicate (Ca / Na), etc.).

[0026] In particular, from the viewpoint of resistance to treading from the medium and impact resistance, it is preferable that the plate-like powder in component (A) contains at least one selected from the group consisting of mica, sericite, talc, and synthetic fluorophlogopite. Here, "containing at least one selected from the group consisting of mica, sericite, talc, and synthetic fluorophlogopite" means that it may also contain a composite powder in which mica, sericite, talc, or synthetic fluorophlogopite has been coated. Preferably, mica, sericite, talc, or synthetic fluorophlogopite is not a composite powder (containing two or more powders).

[0027] The average particle size of component (A) is preferably 3 μm or larger, and more preferably 10 μm or larger, in terms of trajectory from the medium. The upper limit of the average particle size of component (A) is not particularly limited, but is usually 1000 μm or less, may be 500 μm or less, 100 μm or less, less than 50 μm, or 25 μm or less.

[0028] Component (A) may be used alone or in combination of two or more components.

[0029] The content of component (A) relative to the cosmetic composition is preferably 1 to 30% by mass, more preferably 1 to 25% by mass, and even more preferably 3 to 20% by mass, from the viewpoint of the effects of the present invention.

[0030] The amino-modified silicone used as a surface treatment agent is preferably a silicone compound having an amino group or an ammonium group. The amino-modified silicone may be in any form, such as liquid or solid, and may or may not have a cross-linked structure. Among these, it is preferable to use an amino-modified silicone having a cross-linked structure from the viewpoint of superior impact resistance, and it is preferable to use a cross-linked product of dimethiconol and 3-aminopropyltriethoxysilane as the amino-modified silicone used as a surface treatment agent.

[0031] [Amino-modified silicone without cross-linking structure] The amino-modified silicone without a crosslinking structure is not particularly limited and may be either an amino-modified silicone oil in which all or some of the terminal hydroxyl groups are occluded with methyl groups, etc., or amodimethicone with unoccluded terminals. From the viewpoint of adhesion to the medium, amodimethicone surface treatment is preferred as the amino-modified silicone surface-treated powder without a crosslinking structure.

[0032] Examples of amino-modified silicones that do not have a cross-linking structure include those represented by the following general formula (1).

[0033] [ka]

[0034] [In formula (1), R is independently a hydroxyl group, a hydrogen atom, or R a Show, R a represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 20 carbon atoms, preferably R is a methyl group, and X is R a ,-Q-NH(CH2) n NH2-OR a Or it shows a hydroxyl group, preferably R a is a methyl group or a hydroxyl group, Q represents a divalent hydrocarbon group having 1 to 8 carbon atoms, preferably a propylene group, an isopropylene group, or an isobutylene group. n represents a number from 1 to 5, preferably 2. p and q represent a number such that their sum is preferably 2 or more and less than 2000 on a number mean, more preferably 20 or more and less than 2000, and even more preferably 30 or more and less than 1000.

[0037] Here, the functional group equivalent means the mass of the siloxane skeleton per amino group or ammonium group. The notation unit g / mol is the value converted per 1 mol of amino group or ammonium group. Therefore, the smaller the value of the functional group equivalent, the higher the ratio of amino group or ammonium group in the molecule.

[0038] Specific examples of suitable commercially available amino-modified silicones include SF8451C (manufactured by Toray Dow Corning Silicone Co., Ltd., viscosity 600 mm 2 / s, functional group equivalent 1700 g / mol), SF8452C (manufactured by Toray Dow Corning Silicone Co., Ltd., viscosity 700 mm 2 / s, functional group equivalent 6400 g / mol), SF8457C (manufactured by Toray Dow Corning Silicone Co., Ltd., viscosity 1200 mm 2 / s, functional group equivalent 1800 g / mol), KF8003 (manufactured by Shin-Etsu Chemical Co., Ltd., viscosity 1850 mm 2 / s, functional group equivalent 2000 g / mol), KF8004 (manufactured by Shin-Etsu Chemical Co., Ltd., viscosity 800 mm 2 / s, amino equivalent 1500 g / mol), KF867S (manufactured by Shin-Etsu Chemical Co., Ltd., viscosity 1300 mm 2 / s, functional group equivalent 1700 g / mol), XF42-B8922 (manufactured by Momentive Performance Materials Inc., viscosity 70000 mm 2 / s, functional group equivalent 13000 g / mol) and other amino-modified silicone oils, and amodimethicone emulsions such as SM8704C (manufactured by Toray Dow Corning Silicone Co., Ltd., functional group equivalent 1800 g / mol).

[0039] The above amino-modified silicone is not particularly limited, but from the viewpoint of uniformly coating the powder and obtaining the uniformity of the cosmetic film, 100 to 3000 mm 2It is more preferable that the kinematic viscosity is in the range of / s (25°C). This may be used in the form of an emulsion. This amino-modified silicone emulsion can be prepared, for example, by mechanically mixing the amino-modified silicone and a solvent at high shear, by emulsifying the amino-modified silicone with water and an emulsifier, or by a combination thereof, or by emulsion polymerization.

[0040] [Amino-modified silicone with a cross-linked structure] The amino-modified silicone having a crosslinked structure is not particularly limited, but examples include crosslinked products of both-terminal reactive diorganopolysiloxanes and aminosilanes, and more specifically, crosslinked products of dimethiconol and aminosilanes. In the following, surface treatment with crosslinked products of dimethiconol and aminosilanes may be simply referred to as dimethiconol and aminosilane treatment, etc.

[0041] A biterminally reactive diorganopolysiloxane refers to a biterminally reactive diorganopolysiloxane having reactive groups (e.g., hydroxyl groups) at both ends of a linear diorganopolysiloxane skeleton, and preferably has a structure represented by the following formula (2).

[0042] [ka]

[0043] R 1 is a hydroxyl group, R 2 Each of these is an unsubstituted or substituted hydrocarbon group having 1 to 20 carbon atoms, and L is 3 to 10,000.

[0044] R 2Examples include alkyl groups such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosyl, docosyl, tricosyl, and tetracosyl groups; and cycloalkyl groups such as cyclobutyl, cyclopentyl, cyclohexyl, and cycloheptyl groups. Examples include aryl groups such as phenyl, tolyl, and naphthyl groups; aralkyl groups such as benzyl, phenethyl, and β-phenylpropyl groups; and hydrocarbon groups in which some or all of the hydrogen atoms bonded to the carbon atoms of these groups are substituted with atoms such as halogen atoms (fluorine, chlorine, bromine, iodine) and / or substituents such as acryloyloxy, methacryloyloxy, epoxy, glycidoxy, amino, mercapto, and carboxyl groups.

[0045] The reactive diorganopolysiloxanes at both ends are preferably dimethiconol.

[0046] The molecular weight of the double-ended reactive diorganopolysiloxane is preferably 300 to 200,000. The double-ended reactive diorganopolysiloxane can be in the form of an oil, a dilution with other silicone oils, or an emulsion consisting of an emulsion with water. The emulsion can be obtained by mechanically emulsifying the double-ended reactive diorganopolysiloxane oil, or by emulsion polymerization using a low molecular weight siloxane as a starting material. Any type of emulsion can be used as long as the emulsifier used for emulsification is highly safe. As a method for producing the emulsion, the method described in Japanese Patent Publication No. 2016-145213 can be used. For example, methods for preparing an aqueous emulsion of the double-ended reactive diorganopolysiloxane of formula (2) include emulsion polymerization using a low molecular weight cyclic siloxane such as octamethylcyclotetrasiloxane as a starting material, and mechanical emulsification using an emulsification and mixing apparatus of a system containing at least an oily double-ended reactive diorganopolysiloxane, a surfactant, and water.

[0047] As the aminosilane, (aminoalkyl)alkoxysilanes are preferred, and examples include compounds represented by the following formulas (3) or (4).

[0048] [ka]

[0049] In general formula (3) or (4), R 3 , and R 5 Each of these is an alkyl group having 1 to 10 carbon atoms (preferably 1 to 8, more preferably 1 to 6, and particularly preferably 2 to 3 carbon atoms) independently substituted with an amino group, and R 4 , and R 7 Each of these is an alkyl group having 1 to 10 carbon atoms (preferably 1 to 8, more preferably 1 to 4, and particularly preferably 1 to 2), and R 6 R is an alkylene group having 1 to 10 carbon atoms (preferably 1 to 8, more preferably 1 to 4, and particularly preferably 1 to 3). 3 , and R 5 The number of amino group substitutions in is preferably 1 to 3, and more preferably 1 (an aminoalkyl group). Multiple R 3 ~R 7 These substituents may be the same or different. In general formula (3) or (4), n and m represent integers from 1 to 4. n and m are preferably 2 or 3, and more preferably 3.

[0050] Examples of (aminoalkyl)alkoxysilanes include N-2(aminoethyl)3-aminopropyltrimethoxysilane, N-2(aminoethyl)3-aminopropyltriethoxysilane, 3-aminopropyltrimethoxysilane, and 3-aminopropyltriethoxysilane. 3-aminopropyltriethoxysilane is preferred from the viewpoint of the safety of reaction by-products.

[0051] The crosslinked product of dimethiconol and aminosilane is preferably a silicone gel. A silicone gel is a polymer having a micro-three-dimensional crosslinked structure of diorganopolysiloxane that does not have rubber elasticity, i.e., rubber hardness. Specifically, it is a silicone gel obtained by reacting aminosilane with a starting material in which the terminally reactive diorganopolysiloxane of formula (2) is in the form of a water suspension or water emulsion.

[0052] The cross-linking product content of dimethiconol and aminosilane in the dimethiconol and aminosilane cross-linking product treated powder is preferably 0.01 to 30% by mass, and more preferably 1 to 10% by mass, relative to the dimethiconol and aminosilane cross-linking product treated powder. The cross-linking product content is approximately equal to the amount of cross-linking product processed during the production of the cross-linking product treated powder.

[0053] A known method can be used to produce a crosslinked product of dimethiconol and aminosilane, for example, the method described in Japanese Patent Application Publication No. 2016-145213. Specifically, it can be obtained by reacting a dimethiconol emulsion, preferably an aqueous emulsion, with aminosilane. A catalyst may be used during the reaction. When the crosslinked product is in the form of a silicone gel, the content ratio of dimethiconol to aminosilane is, for example, dimethiconol:aminosilane = 100:0.1 to 100:35 (mass ratio) and 100:5 to 100:25 (mass ratio).

[0054] In this process, the surface treatment of the powder to be treated may be performed after manufacturing the silicone gel, or the silicone gel may be deposited on the surface of the powder particles by mixing dimethiconol and aminosilane in the presence of the powder to be treated and carrying out a hydrolysis-condensation reaction, followed by heating to fix the crosslinking product to the particle surface. It is preferable to use an aqueous solvent for the hydrolysis-condensation reaction, and examples of aqueous solvents include water, ethanol, isopropyl alcohol, and mixtures thereof. Preferably, the aqueous solvent is water. The temperature during the hydrolysis-condensation reaction is preferably, for example, 5 to 60°C, and more preferably 15 to 30°C. The heating conditions after the hydrolysis-condensation reaction are set as appropriate, but for example, 100 to 180°C for 3 hours or more. The mixed mass ratio of the powder to be treated and the crosslinking product is, for example, powder to be treated:crosslinking product = 99.99 to 0.01 to 70:30, and 99:1 to 90:10.

[0055] Examples of commercially available amino-modified silicone treated powders of component (A) include, for example, amodimethicone treatment, mica Y-2300WA3 (manufactured by Yamaguchi Mica Co., Ltd.) and EX-15WA3 (mother: mica) (manufactured by Yamaguchi Mica Co., Ltd.); and dimethiconol and aminopropyltriethoxysilane (crosslinked product) treatments, such as SE-TA-13, SE-TA-46, SE-TA-68, SE-TA-EX (mother: talc) (manufactured by Miyoshi Chemical Co., Ltd.), SE-MA-23 (mother: mica) (manufactured by Miyoshi Chemical Co., Ltd.), and SE-S-100S (mother: sericite) (manufactured by Miyoshi Chemical Co., Ltd.).

[0056] (Component (B): A powder consisting of plate-shaped powders surface-treated with silicone) Component (B) is a powder obtained by surface-treating a plate-shaped powder with a silicone other than amino-modified silicone.

[0057] Being in plate-like form allows for good shedding of the cosmetic from the medium and provides a smooth feel when the cosmetic is applied to the skin. On the other hand, plate-like powders tend to peel off from the medium in clumps when subjected to impact, but the configuration of this embodiment makes it possible to improve adhesion to the medium while maintaining the smooth feel provided by the inclusion of plate-like powders.

[0058] Examples of plate-shaped powders include, specifically, mica, sericite, talc, synthetic fluorophlogopite, plate-shaped barium sulfate, plate-shaped calcium sulfate, borosilicate (Ca / Al), borosilicate (Ca / Na), (PET / polymethyl methacrylate) laminate, inorganic plate-shaped powders such as (fluoride / hydroxylated / oxidized) / (Mg / K / silicon), and composite powders obtained by coating these plate-shaped powders (titanium dioxide coated mica, iron oxide coated mica, titanium dioxide coated synthetic fluorphlogopite, titanium dioxide coated borosilicate (Ca / Al), titanium dioxide coated borosilicate (Ca / Na), titanium dioxide coated glass powder, silicon dioxide / titanium dioxide coated mica, silicon dioxide / titanium dioxide coated borosilicate (Ca / Na), etc.).

[0059] In particular, from the viewpoint of resistance to treading from the medium and impact resistance, it is preferable that the plate-like powder in component (B) contains at least one selected from the group consisting of mica, sericite, talc, and synthetic fluorophlogopite. Here, "containing at least one selected from the group consisting of mica, sericite, talc, and synthetic fluorophlogopite" means that it may also contain a composite powder in which mica, sericite, talc, or synthetic fluorophlogopite has been coated. Preferably, mica, sericite, talc, or synthetic fluorophlogopite is not a composite powder (containing two or more powders).

[0060] The average particle size of component (B) is preferably 3 μm or larger, and more preferably 10 μm or larger, in terms of trajectory from the medium. The average particle size of component (B) can be calculated from image data obtained by measuring 100 particles using a desktop scanning electron microscope (proX PREMIUM, Thermo Fisher Scientific) at an acceleration voltage of 5 to 15 kV and a magnification of 1000 to 25000 times. The longest diameter (maximum diameter) of component (B) is used. There is no particular upper limit to the average particle size of component (B), but it is usually 1000 μm or less, may be 500 μm or less, may be 100 μm or less, may be less than 50 μm, or may be 25 μm or less.

[0061] Component (B) may be used alone or in combination of two or more components.

[0062] The content of component (B) is preferably 1 to 30% by mass, more preferably 3 to 25% by mass, and even more preferably 5 to 20% by mass, relative to the cosmetic composition.

[0063] The mass ratio of component (A) to component (B) (A) / (B) (hereinafter also simply referred to as (A) / (B)) is preferably 0.1 to 3 from the viewpoint of the effects of the present invention, and more preferably 0.3 to 2.5 from the viewpoint of preventing the cosmetic from shedding from the medium. Furthermore, (A) / (B) is preferably 0.5 or more from the viewpoint of suppressing shedding from the medium, and may be 0.8 or more. Furthermore, (A) / (B) is preferably 2.3 or less from the viewpoint of suppressing the formation of aggregates, and may be 2.0 or less. In this case, the total amount of component (A) and component (B) is preferably 10 to 30% by mass, and more preferably 15 to 25% by mass from the viewpoint of suppressing the formation of aggregates. Preferred embodiments of the present invention are: (A) / (B) is 0.1 to 3 and the total amount of component (A) and component (B) is 10 to 30% by mass; (A) / (B) is 0.1 to 3 and the total amount of component (A) and component (B) is 15 to 25% by mass; (A) / (B) is 0.3 to 2.5 and the total amount of component (A) and component (B) is 10 to 30% by mass; and (A) / (B) is 0.3 to 2.5 and the total amount of component (A) and component (B) is 15 to 25% by mass.

[0064] The silicone treatment agent used as a surface treatment agent is not particularly limited as long as it is commonly used in cosmetics, but examples include dimethylpolysiloxane (dimethicone), methylhydrogenpolysiloxane (hydrogen dimethicone, methicone), high viscosity silicone, crosslinked silicone, phenyl-modified silicone, acrylic-silicone graft copolymer, alkylsilane, silicone resin, etc., and one or more of these can be used.

[0065] Specifically, when expressed using INCI names (International Nomenclature Cosmetic Ingredient labeling names), examples include dimethicone, methicone, hydrogen dimethicone, diphenylsiloxyphenyl trimethicone, diphenyl dimethicone, triethoxysilylethyl polydimethylsiloxyethyl dimethicone, triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone, (acrylates / tridecyl acrylate / triethoxysilylpropyl methacrylate / dimethicone methacrylate) copolymer, and triethoxycaprylylsilane. One or more of these can be used. In particular, from the viewpoint of suppressing the formation of aggregates, the silicone treatment agent used as a surface treatment agent is preferably at least one selected from the group consisting of dimethicone, methicone, hydrogen dimethicone, diphenylsiloxy phenyl trimethicone, and diphenyl dimethicone, and more preferably at least one selected from the group consisting of dimethicone, methicone, hydrogen dimethicone, and diphenylsiloxy phenyl trimethicone.

[0066] Furthermore, the amount of silicone treatment agent in component (B) varies depending on the type and combination of treatment agents and the type of base powder, but the amount of treatment agent is preferably 0.5 to 30% by mass, and more preferably 1 to 25% by mass, relative to the silicone-treated powder.

[0067] Furthermore, the method of silicone treatment is not particularly limited, and commonly known methods, such as a wet method using a solvent or a dry method performed in the gas phase, can be used. For example, it can be obtained by adding a mixed solution of the treatment agent and a volatile organic solvent such as isopropyl alcohol to the base powder, uniformly stirring it with a mixer such as a Henschel mixer, and removing the solvent in a heating step.

[0068] (Ingredients (C): Dextrin fatty acid ester) Dextrin fatty acid esters are esters of dextrin and fatty acids.

[0069] The dextrin preferably has an average degree of polymerization of glucose of 3 to 150, and more preferably of 10 to 100. The sugar chain of the dextrin may be linear, branched, or cyclic.

[0070] The fatty acid in the dextrin fatty acid ester is preferably a fatty acid having 4 to 26 carbon atoms, and more preferably a saturated fatty acid having a straight or branched chain with 4 to 26 carbon atoms.

[0071] Examples of branched saturated fatty acids having 4 to 26 carbon atoms include isobutyric acid, isovaleric acid, 2-ethylbutyric acid, ethylmethylacetic acid, isoheptanoic acid, 2-ethylhexanoic acid, isononanoic acid, isodecanoic acid, isotridecanoic acid, isomyristateic acid, isopalmitic acid (2-hexyldecanoic acid), isostearic acid, isoarachinic acid, isohexacosanic acid, etc., and one or more of these can be appropriately selected or used in combination. Of these, those with 8 to 24 carbon atoms are more preferred.

[0072] Examples of straight-chain saturated fatty acids having 2 to 22 carbon atoms include acetic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, and behenic acid. One or more of these can be appropriately selected or combined. Among these, those having 8 to 22 carbon atoms are preferred, and those having 12 to 22 carbon atoms are particularly preferred.

[0073] Examples of dextrin fatty acid esters include dextrin octanoate, dextrin laurate, dextrin palmitate, dextrin myristate, dextrin stearate, dextrin behenate, dextrin coconut oil fatty acid, (palmitic acid / octanoic acid) dextrin, (palmitic acid / 2-ethylhexanoic acid) dextrin, (palmitic acid / hexyldecanoic acid) dextrin, and dextrin isostearate. Examples of commercially available dextrin fatty acid esters include "Leopal KL2," "Leopal KS2," "Leopal TT2," "Leopal TL2," "Leopal MKL2," "Leopal WX," and "Unifilma HVY" manufactured by Chiba Flour Milling Co., Ltd.

[0074] Of these, it is most preferable that component (C) is isostearate dextrin, as this further improves the suppression of shedding from the medium. Isostearate refers to one or more branched stearic acids. For example, 5,7,7-trimethyl-2-(1,3,3-trimethylbutyl)-octanoic acid can be produced by the oxo reaction of isobutylene dimer to form a branched aldehyde with 9 carbon atoms, then by aldol condensation of this aldehyde to form a branched unsaturated aldehyde with 18 carbon atoms, and then by hydrogenation and oxidation (hereinafter abbreviated as "aldol condensation type"), which is commercially available, for example, from Nissan Chemical Industries, Ltd. 2-Heptylundecanoic acid can be produced by subjecting nonyl alcohol to a Guerbet reaction followed by oxidation. This is commercially available, for example, from Mitsubishi Chemical Corporation. Similar mixtures with slightly different branching positions are commercially available from Nissan Chemical Industries, Ltd., and a type in which the starting alcohol is not linearly saturated but has two methyl branches is also commercially available from Nissan Chemical Industries, Ltd. (hereinafter collectively referred to as "Guerbet reaction type"). Methyl-branched isostearic acid can be obtained, for example, as a byproduct of oleic acid dimer production [for example, described in J. Amer. Oil Chem. Soc., 51, 522 (1974)], and is commercially available from companies such as Emery in the United States (hereinafter hereinafter referred to as "Emery type"). The starting materials for dimer acids, which are the starting materials for Emery type isostearic acid, may include not only oleic acid but also linoleic acid, linolenic acid, etc.

[0075] Dextrin fatty acid esters may be used individually or in combination of two or more types.

[0076] The content of component (C) is, for example, 0.005 to 10% by mass in the cosmetic composition, preferably 0.01 to 5% by mass, and more preferably 0.05 to 3% by mass. Within this range, the effects of the present invention are easily achieved.

[0077] The mass ratio of component (A) to component (C), (A) / (C), is preferably 1 to 200, more preferably 5 to 100 from the viewpoint of preventing the cosmetic from leaching or shedding from the medium, even more preferably greater than 5 and 80 or less from the viewpoint of preventing the cosmetic from leaching or aggregation from the medium, and even more preferably 8 to 80.

[0078] (Component (D): Non-volatile oil that is liquid at 25°C) In this specification, "oil" refers to an oil-soluble compound that is insoluble (or sparingly soluble) in water, for example, a substance with a water solubility (10¹³.25 hPa, 20°C) of less than 2 g / 100 gH₂O. "Liquid at 25°C" means that it has fluidity at 25°C, for example, a viscosity of 20,000 mPa·s or less at 25°C. Furthermore, a non-volatile oil is, for example, an oil with a boiling point of 260°C or higher at atmospheric pressure. Note that "oil" here refers to oils that are incorporated into cosmetics on their own, and does not include oils used as surface treatment agents. As described below, since volatile components are volatilized during film formation on the medium, it is preferable that cosmetics do not contain volatile oils.

[0079] The non-volatile oil agent that is liquid at 25°C in the present invention is not particularly limited as long as it is commonly used in cosmetics, and includes, for example, liquid paraffin (mineral oil), hydrocarbon oils such as squalane and squalene, fatty acids such as isostearic acid and oleic acid, higher alcohols such as octyldodecanol and tetradecyldecanol, isopropyl palmitate, isopropyl myristate, isopropyl stearate, isobutyl stearate, 2-ethylhexyl stearate, isopropyl isostearate, butyl isostearate, decyl isostearate, lauryl isostearate, isodecyl isodecanoate, isodecyl isononanoate, isotridecyl isononanoate, isononyl isononanoate, diisostearyl malate, neopentyl glycol dioctanoate, propylene glycol dicaprate, propylene glycol dicaprylate, and glyceryl tri-2-ethylhexanoate. (Triethylhexanoin), Polyglyceryl monoisostearate, Polyglyceryl diisostearate, Diglyceryl triisostearate, Diglyceryl tetraisostearate, Diethyl sebacate, Cetyl 2-ethylhexanoate, Ethylhexyl palmitate, Octyldodecyl myristate, Oleyl oleate, Ethyl oleate, N-Lauroyl glutamate di(phytosteryl / 2-octyldodecyl), N-Lauro Examples include ester oils such as phytosteryl / behenyl / 2-octyldodecyl yl-glutamate, cholesteryl / 2-octyldodecyl N-lauroyl-glutamate, isopropyl N-lauroyl-sarcosinate, and ethylhexyl methoxycinnamate, as well as silicone oils such as dimethylpolysiloxane (dimethicone), diphenylsiloxyphenyl trimethicone, diphenyldimethicone, and alkoxy-modified polysiloxane.

[0080] In particular, component (D) preferably contains hydrocarbons and / or ester oils. From the viewpoint of the retention of the cosmetic on the medium and the trajectory of the cosmetic, the content of hydrocarbons and / or ester oils in component (D) is preferably more than 50% by mass (up to 100% by mass), and may be 60% by mass or more, 70% by mass or more, 80% by mass or more, or 90% by mass or more.

[0081] Component (D) may be used alone or in combination of two or more components.

[0082] The content of component (D) is not particularly limited, but from the viewpoint of effect expression, it is preferably more than 5% by mass, from the viewpoint of suppressing shedding from the medium, it is preferably more than 10% by mass, and more preferably 15% by mass or more. Furthermore, from the viewpoint of cosmetic effect, the content of component (D) is preferably 30% by mass or less relative to the cosmetic composition, and from the viewpoint of suppressing aggregate formation, it is more preferably 25% by mass or less. The content of component (D) in the cosmetic composition is preferably more than 5% by mass and 30% by mass or less, more preferably more than 10% by mass and 25% by mass or less, and even more preferably 15 to 25% by mass.

[0083] Furthermore, in the oils (liquid oil, semi-solid oil, solid oil), component (D) is preferably 80% by mass or more (upper limit 100% by mass), more preferably exceeding 90% by mass, even more preferably 95% by mass or more, and even more preferably 98% by mass or more, from the viewpoint of suppressing aggregate formation and ensuring the quality of the cosmetic. In other words, the content of semi-solid oil and / or solid oil (oils other than liquid oil) is preferably 20% by mass or less (lower limit 0% by mass), more preferably less than 10% by mass, even more preferably 5% by mass or less, and even more preferably 2% by mass or less, in the oils (liquid oil, semi-solid oil, solid oil).

[0084] (Other powders) The thin-film powder cosmetic composition of this embodiment may contain powders other than components (A) and (B) from the viewpoint of adjusting the feel.

[0085] The powder is not particularly limited in terms of shape (plate-like, spindle-like, needle-like, etc.), particle size (fuzzy, fine particles, pigment-grade, etc.), particle structure (porous, non-porous, etc.), and examples include inorganic powders, lustrous powders, organic powders, colored pigments, composite powders, polyethylene terephthalate-aluminum-epoxy laminated powder, polyethylene terephthalate-polymethyl methacrylate laminated powder, etc.

Furthermore, the cross-linked organopolysiloxane polymer may be incorporated into the cosmetic in the form of a silicone gel consisting of the cross-linked organopolysiloxane polymer and a solvent. Commercially available silicone gels can be used for this purpose, such as KSG-18A, KSG-16, KSG-15AP (all manufactured by Shin-Etsu Silicone Co., Ltd.) and Elastomer Blend DC9045 (manufactured by Toray Dow Corning Co., Ltd.).

[0090] Examples of composite powders include barium sulfate-coated titanium mica, organic pigment-treated titanium mica, barium sulfate-coated titanium mica, titanium oxide-coated silicon dioxide, and zinc oxide-coated silicon dioxide.

[0091] The powder may be surface-treated using one or more surface treatment agents. Examples of surface treatments include silicone treatment, trialkoxyalkylsilane treatment, alkyl titanate treatment, oil treatment, fluorine compound treatment, phospholipid treatment, and fatty acid treatment.

[0092] The processing amount is preferably 0.5 to 30% by mass relative to the powder, and more preferably 1 to 20% by mass.

[0093] While not particularly limited, talc, mica, synthetic mica, and surface-treated powders thereof can be used as corrective materials in powder cosmetics (materials other than functional materials that impart cosmetic effects, such as pigments, in addition to components (A) to (D)). These corrective materials may be present in the cosmetic in amounts of, for example, 20 to 90% by mass, or 40 to 80% by mass.

[0094] (optional ingredient) In addition to the above-mentioned components, the thin-film powder cosmetic composition of this embodiment may appropriately contain higher alcohols, surfactants, polymers, UV absorbers, preservatives, antibacterial agents, antioxidants, alcohols, beauty ingredients, etc., which are commonly used in cosmetics, to the extent that they do not interfere with the effects of the present invention.

[0095] (Uses and cosmetics) Another embodiment is a cosmetic product in which the thin film powder cosmetic composition of the above embodiment is supported on a medium.

[0096] The medium can be planar, but from a design perspective, it may also be three-dimensional (a shape with a portion separated from the plane). Any shape is possible, and it is not limited to rectangles or similar shapes; various shapes such as petals and feathers can be adopted, taking design considerations into account. Furthermore, the medium may be transparent or opaque, and may be colored or uncolored.

[0097] Materials that make up the medium include paper, resins (polyolefins, polyvinyl chloride, polyesters such as polyethylene terephthalate, etc.), nonwoven fabrics, and cloth.

[0098] As a medium, a sheet-like medium is preferable because it allows cosmetics to adhere easily. The thickness of the sheet-like medium is, for example, 10 to 500 μm. The sheet-like medium may be used as a single sheet (one unit) or as multiple sheets (multiple sheets may be used to constitute a cosmetic product).

[0099] Furthermore, the thin film powder cosmetic may be supported (held) on one side of the sheet-like medium, or on both sides. Since it is possible to use it multiple times (three or more times), it is preferable that the thin film powder cosmetic be supported (held) on both sides of the sheet-like medium. Note that if it is used only once, it is not a particular problem even if a large amount of cosmetic is taken, but if it is used multiple times, if too much cosmetic is taken in one go, there will be no cosmetic left for subsequent uses, so it is necessary that the amount taken each time is appropriate.

[0100] Conventional cosmetic samples have the cosmetic formed on one side of a (sheet-like) medium. However, compared to this form, a form in which a thin film of powdered cosmetic is supported (held) on both sides (or even the entire surface) of the medium is more difficult to maintain the cosmetic's retention. With the configuration of the above embodiment, even if the cosmetic is supported on both sides of the (sheet-like) medium, the amount of cosmetic missing or powder scattering upon impact is reduced.

[0101] The uses of the thin film cosmetic composition of the above embodiment and the cosmetic product on which it is supported on a medium are not particularly limited, but they are preferably used in makeup cosmetics such as foundation, primer, eye color, eyeliner, blush, face powder, and eyebrow products. In particular, since the thin film cosmetic composition and the cosmetic product on which it is supported on a medium can be applied as a uniform film containing a large amount of powder, the forms of foundation, eye color, blush, and face powder are preferred.

[0102] (Manufacturing method) The method for producing the thin film cosmetic composition of the above embodiment and the cosmetic composition supported thereon on a medium is not particularly limited, but the following method is preferred.

[0103] The following components (A) to (D); (A) A powder obtained by surface-treating a plate-shaped powder with amino-modified silicone, (B) A powder obtained by surface-treating plate-shaped powder with silicone (excluding component (A)), (C) Dextrin fatty acid ester, (D) Non-volatile oil in liquid form at 25°C The method involves forming a thin film on a medium using a mixture of a cosmetic base and a solvent, which includes [the specified ingredient].

[0104] Furthermore, one aspect of the present invention comprises the following components (A) to (D); (A) A powder obtained by surface-treating a plate-shaped powder with amino-modified silicone, (B) A powder obtained by surface-treating plate-shaped powder with silicone (excluding component (A)), (C) Dextrin fatty acid ester, (D) Non-volatile oil in liquid form at 25°C This is a thin-film cosmetic composition formed using a mixture of a cosmetic base and a solvent, which include [the specified ingredient].

[0105] Furthermore, one aspect of the present invention comprises the following components (A) to (D); (A) A powder obtained by surface-treating a plate-shaped powder with amino-modified silicone, (B) A powder obtained by surface-treating plate-shaped powder with silicone (excluding component (A)), (C) Dextrin fatty acid ester, (D) Non-volatile oil in liquid form at 25°C This cosmetic product is formed by creating a thin film of cosmetic material on a medium using a mixture of a cosmetic base and a solvent, which contains [the specified ingredient].

[0106] The method for producing the cosmetic base before mixing the solvent is not particularly limited. For example, one method involves mixing and dispersing component (A), component (B), and other powders in a Henschel mixer or the like, and then further mixing in component (C) and component (D).

[0107] Preferably, the solvent to be mixed with the cosmetic base is a volatile compound with a boiling point of 260°C or lower at atmospheric pressure. Specifically, examples include water; low-boiling point alcohols such as ethyl alcohol, isopropyl alcohol, and n-butanol; low-boiling point hydrocarbon oils such as isododecane, isohexadecane, and light liquid isoparaffin; low-polymerization linear or cyclic silicone oils such as dimethylpolysiloxane, methyl trimethicone, octamethylcyclotetrasiloxane, and decamethylcyclopentasiloxane; and low-boiling point fluorinated compounds such as low-boiling point perfluoropolyethers. These solvents can be used individually or as a mixture of two or more.

[0108] In particular, from the viewpoint of powder dispersibility, the solvent preferably contains a low-boiling point alcohol and / or a low-boiling point hydrocarbon oil.

[0109] The amount of solvent mixed is arbitrarily selected to the extent that it imparts fluidity to the medium, allowing for coating or spraying (aerosolization) to form a cosmetic film. For example, it is preferable to use 10 to 200 parts by mass of solvent per 100 parts by mass of cosmetic base, and more preferably 50 to 200 parts by mass. Within this range, the fluidity of the powder and the removal of the solvent are good.

[0110] Here, fluidity refers to the state in which a mixture of a cosmetic base, mainly composed of powder, and a solvent is placed in a container with an inner diameter of 2.47 cm, a body diameter of 4.05 cm, and a total height of 7.4 cm (Daiichi Glass Co., Ltd.'s "Pharmaceutical Bottle PS-6K"), which is then sealed with the included lid. When the container is tilted 90° and left to stand for 1 minute at 25°C and 1 atmosphere, a portion of the mixture adheres to the inside of the lid.

[0111] Next, the liquid or paste-like mixture (cosmetic slurry) obtained by mixing with the solvent is brought into contact with the medium. Possible contact methods include, for example, immersing the medium in the mixture, spraying the mixture onto the surface of the medium (spray method), or screen printing the mixture onto the medium. In this process, the amount (thickness) of the cosmetic product carried on the medium can be adjusted by controlling the immersion or spraying time, the number of times, and the concentration of the cosmetic slurry used.

[0112] The medium may also have an adhesive layer formed from the adhesive on the base-forming surface.

[0113] The method for forming a thin film of cosmetic on a medium may be immersion, spraying, or coating. Among these, immersion or spraying is preferred because it allows for the formation of a uniform thin film.

[0114] Subsequently, the solvent is usually removed. The method of solvent removal is not particularly limited, but for example, drying at 20 to 80°C is preferred. The drying time varies depending on the type of solvent and the drying temperature, but for example, it is 1 to 60 minutes. [Examples]

[0115] The effects of the present invention will be explained using the following examples and comparative examples. In the examples, the units "parts" or "%" may be used, but unless otherwise specified, they represent "parts by mass" or "mass%". Unless otherwise specified, each operation is performed at room temperature (25°C).

[0116] Examples 1-28, Comparative Examples 1-9: Face Powder Face powders were prepared according to the formulations shown in Table 1 below.

[0117] (Manufacturing method) a. Components 1-13 and 22 were mixed uniformly. b. Components 14-21 were heated and dissolved, added to a and mixed uniformly to obtain a cosmetic base. 100 parts of CB cosmetic base were added to 100 parts of solvent (isopropyl alcohol) and stirred to prepare a cosmetic slurry. A paper medium with a diameter of approximately 4 cm and a thickness of 60 μm was impregnated (immersed) into a dc cosmetic slurry, allowing the cosmetic slurry to be held on the paper medium. The amount applied after drying was set to approximately 0.5 g. The solvent was removed by drying in a 60°C forced-air dryer for 5 minutes, and a cosmetic (face powder) was obtained in which a thin film of cosmetic (300 μm thick) was supported on both sides of the paper medium (sheet-like substrate).

[0118] (Evaluation method) Evaluation 1: Suppression of aggregate formation For each sample, the presence of powder aggregates (bulbs) on the surface of the cosmetic product was visually inspected.

[0119] (Evaluation Criteria) ◎: No aggregates are observed at all. ○: Few aggregates are observed (1-2) △: A few aggregates are visible (3-4 pieces) ×: Aggregates are clearly visible (5 or more).

[0120] Evaluation 2: Suppression of shedding from the sheet-like medium due to impact. Each sample was placed in a plastic container, dropped from a height of 10 cm at a 10-degree angle, and then its condition was assessed.

[0121] (Evaluation Criteria) ◎: No change ○: One or two chips are observed. △: 3 to 5 chips are observed. ×: More than 6 chips are observed.

[0122] Rating 3: Trading of cosmetics from the media For each sample, a usage test was conducted by a panel of 20 experts. Each panel member evaluated the sample on a four-point scale using the absolute evaluation method described below. The average score was calculated from the sum of all panel members' scores, and the final evaluation was made according to the following criteria.

[0123] Specifically, each cosmetic product was applied using an applicator (such as a brush), and the amount of cosmetic product that adhered was evaluated to determine if it was an appropriate amount for actual use.

[0124] (Evaluation Criteria) 3: The amount of material adhering to the applicator is appropriate. 2: The amount of product adhering to the applicator is slightly too much or slightly too little. 1: Too much or too little product adheres to the applicator. 0: The amount of product adhering to the applicator is excessive, or none at all.

[0125] (Judgment criteria) ◎: 2.5 points or higher ○: 2 points or more, less than 2.5 points △; 1 point or more but less than 2 points ×: Less than 1 point.

[0126] The results of each evaluation are shown in Table 1.

[0132] The face powder in the above example exhibited excellent effects in suppressing aggregate formation, preventing shedding from the medium, and preventing the cosmetic from detaching from the medium. In contrast, Comparative Example 1, which did not contain component (A), was inferior in terms of suppressing shedding from the medium. Comparative Example 2, which did not contain component (B), and Comparative Examples 8 and 9, which used other surface-treated powders instead of component (B), were inferior in terms of suppressing aggregate formation. Furthermore, Comparative Examples 8 and 9, which used other surface-treated powders instead of component (B), also showed reduced detachment from the medium.
