Description

[Technical Field]

[0001] The present invention relates to a powder cosmetic. [Background technology]

[0002] Traditionally, perfumes have been used to impart a user's favorite scent to the body. Cosmetics scented with fragrances have also been used. For example, Patent Document 1 discloses a powder cosmetic containing a fragrance and an extender pigment.

[0003] However, depending on the type of product, such as perfume or cosmetic, there is room for improvement in terms of the persistence of the fragrance, the strength of the fragrance, the diffusion of the fragrance, changes in the quality of the fragrance, etc. Also, depending on the type of product, the fragrance derived from the base may be undesirable.

[0004] Furthermore, in the case of cosmetics that are applied to the skin, various properties are required during use. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-81012 Summary of the Invention

[0006] Powder cosmetics containing fragrances have the risk of causing discomfort to those around them due to the fragrance's short-lasting fragrance, excessive fragrance strength or diffusion, and the tendency for the fragrance to change over time from application.

[0007] In general, when a cosmetic product is improved in a desired property depending on its intended use, it becomes difficult to balance the other properties, and it is difficult to simultaneously satisfy all the properties. Therefore, there is still a demand for a cosmetic product that simultaneously improves many properties while achieving such a balance.

[0008] As a result of intensive research into solving the above-mentioned problems, the present inventors have found that the above-mentioned problems can be solved by blending a specific powdered oil and fat, a liquid oil and fat that is incompatible with the powdered oil and fat, and a fragrance into a powder cosmetic containing a powder component, and have thereby completed the present invention.

[0009] According to the present invention, the following inventions are provided. [1] (A) A powdered oil or fat, containing, when the total triglyceride content is taken as 100% by mass, 80 to 99% by mass of one or more XXX-type triglycerides having a fatty acid residue X with a carbon number of x at positions 1 to 3, and 20 to 1% by mass of one or more X2Y-type triglycerides in which one of the fatty acid residues X in the XXX-type triglycerides is substituted with a fatty acid residue Y with a carbon number of y, wherein the carbon number x is an integer selected from 8 to 12, and the carbon numbers y are each independently an integer selected from x+2 to x+8; (B) Powdered ingredients (excluding (A) powdered oils and fats), (C) a liquid oil or fat that is incompatible with (A) the powdered oil or fat, and (D)Fragrance A powder cosmetic comprising: (A) A powder cosmetic in which the blending amount of powdered oil or fat is 8% by mass or more and 62% by mass or less relative to the total mass of the powder cosmetic. [2] The powder cosmetic according to [1], wherein the blending amount of (A) powdered oil or fat is 10% by mass or more and 60% by mass or less relative to the total mass of the powder cosmetic. [3] (B) The powder cosmetic according to [1] or [2], wherein the blending amount of the powder component is 10% by mass or more and 60% by mass or less relative to the total mass of the powder cosmetic. [4] The powder cosmetic according to any one of [1] to [3], wherein the combined amount of (A) powdered oil and fat and (B) powder component is 50% by mass or more and 85% by mass or less relative to the total mass of the powder cosmetic. [5] The powder cosmetic according to any one of [1] to [4], wherein the blending amount of (C) liquid oil is more than 5% by mass and 35% by mass or less relative to the total mass of the powder cosmetic. [6] The powder cosmetic according to any one of [1] to [5], wherein the blending amount of (D) fragrance is 0.1% by mass or more and 10% by mass or less relative to the total mass of the powder cosmetic. [7] (A) The powder cosmetic according to any one of [1] to [6], wherein the powdered oil or fat contains, when the total triglyceride content is taken as 100% by mass, 90 to 99% by mass of an XXX triglyceride having a fatty acid residue X with a carbon number of x at positions 1 to 3, and 10 to 1% by mass of one or more X2Y triglycerides in which one of the fatty acid residues X in the XXX triglyceride is substituted with a fatty acid residue Y with a carbon number of y, wherein the carbon number x is 10 and the carbon numbers y are each independently an integer selected from x+4 to x+8.

[9] The powder cosmetic according to any one of [1] to [8], wherein the powder component (B) comprises (B1) an oil-absorbing powder and (B2) a metal soap.

[10] The powder cosmetic according to any one of [1] to [9], wherein (C) the liquid oil contains silicone oil.

[0010] According to the present invention, a powder cosmetic is provided which has excellent fragrance persistence after application, fragrance strength at the time of application, low fragrance diffusion, resistance to change in fragrance quality, melting sensation when used, cooling sensation, skin care effect, and makeup effect. DETAILED DESCRIPTION OF THE INVENTION

[0011] [Powder cosmetics] The powder cosmetic according to the present invention comprises, as essential ingredients, (A) powdered oils and fats, (B) powder components (excluding (A) powdered oils and fats), (C) liquid oils and fats that are incompatible with (A) powdered oils and fats, and (D) fragrance. Furthermore, the powder cosmetic according to the present invention may further comprise other ingredients depending on the purpose. The powder cosmetic according to the present invention can simultaneously improve the persistence of fragrance after application, the strength of fragrance upon application, low fragrance diffusion, resistance to changes in fragrance quality, a melting feel when used, a cooling sensation, skin care effects, and makeup effects. Each of the ingredients contained in the powder cosmetic according to the present invention will be described in detail below.

[0012] (A) Powdered oil and fat The powdered oil or fat in the present invention refers to a solid oil or fat that is powdered at room temperature (20°C). The melting point of the powdered oil or fat is preferably 25°C or higher and 50°C or lower, more preferably 25°C or higher and 45°C or lower, even more preferably 25°C or higher and 40°C or lower, and even more preferably 25°C or higher and 35°C or lower. The melting point of the powdered oil or fat can be measured by a conventional method using a differential scanning calorimeter (DSC), and the value at the peak top of the DSC chart is taken as the melting point. If the melting point of the powdered oil or fat is within the above-mentioned range, it will melt easily when applied to the skin, and heat will be removed from the skin, making it easier to feel a cool sensation.

[0013] Powdered fats and oils usually have the form of plate-like crystals or spherical crystals, preferably plate-like crystals. The powdered fats and oils have an average particle size (effective diameter) of, for example, 50 to 400 μm, preferably 50 to 300 μm, more preferably 50 to 250 μm, and even more preferably 50 to 200 μm. Here, the average particle size (effective diameter) is a value (d50) measured by dry measurement using a particle size distribution analyzer (e.g., Microtrac MT3300ExII manufactured by Nikkiso Co., Ltd.) based on the laser diffraction scattering method (ISO 133201, ISO 9276-1). The effective diameter refers to the particle size of a sphere when the measured diffraction pattern of the crystal to be measured matches the theoretical diffraction pattern obtained assuming a spherical shape. Thus, in the case of the laser diffraction scattering method, the effective diameter is calculated by matching the theoretical diffraction pattern obtained assuming a spherical shape with the measured diffraction pattern. Therefore, the same principle can be used to measure whether the crystal to be measured is a plate-like crystal or a spherical crystal.

[0014] The powdered oil or fat contains one or more XXX triglycerides having a fatty acid residue X with a carbon number of x at positions 1 to 3, and one or more X2Y triglycerides in which one of the fatty acid residues X in the XXX triglyceride is substituted with a fatty acid residue Y with a carbon number of y.

[0015] The fatty acid residue X may be a saturated or unsaturated fatty acid residue. The carbon number x of the fatty acid residue X in the XXX triglyceride is an integer selected from 8 to 12, preferably 10. Specific examples of the fatty acid residue X include saturated fatty acid residues such as caprylic acid (C8:0), capric acid (C10:0), and lauric acid (C12:0), with capric acid being preferred. Furthermore, the carbon number y of the fatty acid residue Y in the XXX triglyceride is independently x+2 to x+8, preferably x+4 to x+8. Specific examples of the fatty acid residue Y include saturated fatty acid residues such as myristic acid (C14:0), palmitic acid (C16:0), and stearic acid (C18:0), with myristic acid being preferred.

[0016] When the total triglyceride content is taken as 100% by mass, the XXX triglyceride content is 80 to 99% by mass, preferably 90 to 99% by mass, and the X2Y triglyceride content is 20 to 1% by mass, preferably 10 to 1% by mass. When the contents of XXX triglycerides and X2Y triglycerides are within the above ranges, the presence of a small amount of X2Y triglycerides with a long fatty acid chain length is believed to cause the X2Y triglycerides to be mixed into the fat crystals composed of XXX triglycerides when they are cooled and crystallized from a molten state, disrupting the continuous crystal growth of the XXX triglycerides, resulting in a solid product crystallized in a very sparse state (with increased volume and voids). The resulting solid product has the form of an aggregate of powdery fats and oils crystallized in a very sparse state, and is brittle and easily crumbles even with a slight impact, becoming powdery.

[0017] As the powdered oil or fat, commercially available products can be used. For example, Enequick manufactured by Nisshin Oillio Group, Ltd. is preferably used as the powdered oil or fat.

[0018] For the method of producing powdered oils and fats, reference can be made to Japanese Patent No. 5937771. Specifically, powdered oils and fats can be produced by the following steps. (a) a step of preparing an oil or fat composition, the oil or fat composition containing, when the total triglyceride content is taken as 100% by mass, 80 to 99% by mass of an XXX triglyceride having a fatty acid residue X of carbon number x at positions 1 to 3, and 20 to 1% by mass of an XY triglyceride in which one of the fatty acid residues X in the XXX triglyceride is substituted with a fatty acid residue Y of carbon number y, wherein the carbon number x is an integer selected from 8 to 12, and the carbon numbers y are each independently an integer selected from x+2 to x+8; (b) an optional step of heating the oil and fat composition to melt triglycerides contained in the oil and fat composition to obtain the oil and fat composition in a molten state; (d) cooling the molten oil / fat composition to obtain a powdered oil / fat; It can be produced by a method comprising: In addition, an optional step (c) for accelerating powder production, such as (c1) a seeding step, (c2) a tempering step, and / or (c3) a pre-cooling step, may be included between the steps (b) and (d). Furthermore, the powdered oil obtained in the step (d) may be obtained by a step (e) of pulverizing the solid obtained after the cooling in the step (d) to obtain a powdered oil. The steps (a) to (e) are described below.

[0019] (a) Preparation of oil and fat composition step I The fat and oil composition prepared in step (a) contains the above-mentioned XXX triglyceride (one or more types) and X2Y triglyceride (one or more types) in the above-mentioned mass %. Specifically, for example, the oil and fat composition can be obtained by separately obtaining XXX triglycerides (one or more types) having a fatty acid residue X with a carbon number of x at positions 1 to 3 and YYY triglycerides (one or more types) having a fatty acid residue Y with a carbon number of y at positions 1 to 3, mixing them in a mass ratio of XXX triglyceride / YYY triglyceride of 90 / 10 to 99 / 1 to obtain a reaction substrate (where x is the number of carbon atoms and y is the number of carbon atoms selected from x+2 to x+8), and heating the reaction substrate to cause a transesterification reaction in the presence of a catalyst.

[0020] <Reaction substrate> First, a reaction substrate is obtained by mixing XXX triglyceride (one or more types) and YYY triglyceride (one or more types). The details of the XXX triglyceride are as described above. A YYY triglyceride is a triglyceride having a fatty acid residue Y with a carbon number of y at positions 1 to 3. Here, the carbon number y and the fatty acid residue Y are as described above.

[0021] The XXX triglycerides and YYY triglycerides can also be obtained by direct synthesis using a fatty acid or a fatty acid derivative and glycerin. Taking XXX triglycerides as an example, methods for directly synthesizing XXX triglycerides include (i) a method of directly esterifying a fatty acid having X carbon atoms with glycerin (direct ester synthesis), (ii) a method of reacting a fatty acid alkyl (e.g., fatty acid methyl and fatty acid ethyl) in which the carboxyl group of a fatty acid X having x carbon atoms is bonded to an alkoxyl group with glycerin under basic or acidic catalytic conditions (ester exchange synthesis using fatty acid alkyl), and (iii) a method of reacting a fatty acid halide (e.g., fatty acid chloride and fatty acid bromide) in which the hydroxyl group of the carboxyl group of a fatty acid X having x carbon atoms is substituted with a halogen with glycerin under a basic catalyst (acid halide synthesis). XXX type triglycerides and YYY type triglycerides can be produced by any of the above-mentioned methods (i) to (iii). From the viewpoint of ease of production, however, (i) direct ester synthesis or (ii) transesterification synthesis using a fatty acid alkyl is preferred, and (i) direct ester synthesis is more preferred.

[0022] To produce XXX type triglyceride or YYY type triglyceride by (i) direct ester synthesis, from the viewpoint of production efficiency, it is preferable to use 3 to 5 moles, and more preferably 3 to 4 moles, of fatty acid X or fatty acid Y per mole of glycerin. The reaction temperature in (i) direct ester synthesis of XXX triglyceride or YYY triglyceride may be any temperature at which the water produced by the esterification reaction can be removed from the system, and is, for example, preferably 120° C. to 300° C., more preferably 150° C. to 270° C., and even more preferably 180° C. to 250° C. By carrying out the reaction at 180 to 250° C., XXX triglyceride or YYY triglyceride can be produced particularly efficiently.

[0023] In the (i) direct ester synthesis of XXX triglycerides or YYY triglycerides, a catalyst that promotes the esterification reaction may be used. Examples of the catalyst include acid catalysts and alkaline earth metal alkoxides. The amount of the catalyst used is preferably about 0.001 to 1% by mass based on the total mass of the reaction raw materials. In the (i) direct ester synthesis of XXX type triglycerides or YYY type triglycerides, after the reaction, the catalyst and unreacted raw materials can be removed by known purification treatments such as water washing, alkaline deoxidation and / or deoxidation under reduced pressure, and adsorption treatment. Furthermore, the obtained reaction product can be further purified by decolorization and deodorization treatment.

[0024] These XXX triglycerides and YYY triglycerides are mixed in a XXX triglyceride / YYY triglyceride mass ratio of 90 / 10 to 99 / 1, preferably 93 / 7 to 99 / 1, and more preferably 95 / 5 to 99 / 1. In particular, when the fatty acid residue X has 10 carbon atoms and the fatty acid residue Y has 14 to 18 carbon atoms, the XXX triglyceride / YYY triglyceride mass ratio is preferably 95 / 5 to 99 / 1. Furthermore, when the fatty acid residue X has 12 carbon atoms and the fatty acid residue Y has 16 to 18 carbon atoms, the XXX triglyceride / YYY triglyceride mass ratio is preferably 95 / 5 to 99 / 1.

[0025] <Other triglycerides> The triglycerides used as raw materials for the reaction substrates may include various triglycerides in addition to the above-mentioned XXX triglycerides and YYY triglycerides, as long as the effects of the present invention are not impaired. Examples of other triglycerides include X2Y triglycerides in which one of the fatty acid residues X in the above-mentioned XXX triglycerides is substituted with a fatty acid residue Y, and XY2 triglycerides in which two of the fatty acid residues X in the above-mentioned XXX triglycerides are substituted with a fatty acid residue Y. The amount of the other triglycerides is, for example, 0 to 15% by mass, preferably 0 to 7% by mass, and more preferably 0 to 4% by mass, when the total mass of the XXX triglycerides and YYY triglycerides is 100% by mass. Furthermore, instead of the above-mentioned XXX-type triglycerides and YYY-type triglycerides, naturally occurring triglyceride compositions may be used. Examples of naturally occurring triglyceride compositions include palm kernel oil, palm kernel olein, palm kernel stearin, rapeseed oil, coconut oil, soybean oil, sunflower oil, safflower oil, and palm stearin. These naturally occurring triglyceride compositions may be further modified by hydrogenation or the like to produce hardened oils, partially hardened oils, or highly hardened oils. The amount of the naturally occurring triglyceride composition depends on the amount of XXX triglyceride or YYY triglyceride required to be contained in the naturally occurring triglyceride composition. For example, when X in the XXX triglyceride is capric acid and the YYY triglyceride is derived from extremely hydrogenated palm kernel stearin oil, it is appropriate that the triglyceride having Y residues at positions 1 to 3 contained in the extremely hydrogenated palm kernel stearin oil is contained in the amount required for the above-mentioned YYY triglyceride, i.e., an amount satisfying a mass ratio of XXX triglyceride / YYY triglyceride of 90 / 10 to 99 / 1, preferably 93 / 7 to 99 / 1, and more preferably 95 / 5 to 98 / 2.

[0026] <Other ingredients> In addition to the triglyceride, the raw materials constituting the reaction substrate may optionally contain other components such as partial glycerides, antioxidants, emulsifiers, solvents such as water, etc. The amount of these other components can be any amount as long as it does not impair the effects of the present invention, but for example, when the mass of the obtained reaction substrate is taken as 100 mass%, it is 0 to 5 mass%, preferably 0 to 2 mass%, more preferably 0 to 1 mass%.

[0027] The mixing may be carried out by any known mixing method as long as a homogeneous reaction substrate can be obtained, for example, by using a paddle mixer, an Ajihomo mixer, a Disper mixer, or the like. The mixing may be performed under heating, if necessary. The heating temperature is preferably about the same as that in step (b) described below, for example, 50 to 120°C, preferably 60 to 100°C, more preferably 70 to 90°C, and even more preferably 80°C. When an enzyme is added as a catalyst, it is preferable that water is present as little as possible before the enzyme is added. The amount of water before the enzyme is added is, for example, 10% by mass or less, preferably 0.001 to 5% by mass, more preferably 0.01 to 3% by mass, and even more preferably 0.01 to 2% by mass, based on the mass of the total raw materials. The mixing may be continued for, for example, 5 to 60 minutes, preferably 10 to 50 minutes, and more preferably 20 to 40 minutes.

[0028] <Transesterification reaction> The reaction substrate (a mixture containing XXX triglyceride and YYY triglyceride) is heated and subjected to an interesterification reaction in the presence of a catalyst to obtain an interesterification reaction product (an oil and fat composition containing XXX triglyceride and X2Y triglyceride). The transesterification reaction is not particularly limited, and any commonly used transesterification reaction can be used. Here, the heating is carried out at, for example, 50 to 120°C, preferably 60 to 100°C, more preferably 70 to 90°C, and even more preferably 80°C. The catalyst may be an enzyme, an alkali metal alkoxide, an alkaline earth metal alkoxide, etc. The enzyme may be an immobilized enzyme or a powdered enzyme, but from the viewpoint of enzymatic activity and ease of handling, a powdered enzyme is preferred. Powdered enzymes are enzymes that have been dried and powdered from an enzyme-containing aqueous liquid by methods such as spray drying, freeze drying, or drying after solvent precipitation. Examples of powdered enzymes include, but are not limited to, lipase derived from Alcaligenes sp. (Meito Sangyo Co., Ltd., trade name: Lipase QLM). The immobilized enzyme can be an enzyme immobilized on a carrier such as silica, celite, diatomaceous earth, perlite, polyvinyl alcohol, anion exchange resin, phenol adsorption resin, hydrophobic carrier, cation exchange resin, or chelating resin.

[0029] In the alkali metal alkoxides and alkaline earth metal alkoxides that can be used as catalysts, lithium, sodium, potassium, etc. can be preferably used as the alkali metal. Magnesium and calcium can be preferably used as the alkaline earth metal. Examples of alkoxides include methoxide, ethoxide, propoxide, n-butoxide, t-butoxide, etc., with methoxide and ethoxide being preferred. Preferred alkali metal alkoxides and alkaline earth metal alkoxides include sodium methoxide, sodium ethoxide, magnesium methoxide, magnesium ethoxide, etc., with sodium methoxide being more preferred. These catalysts may be used alone or in combination of two or more, but it is preferable not to use an enzyme catalyst and an alkoxide catalyst at the same time. The amount of catalyst may be any amount that allows the transesterification reaction to proceed sufficiently, and is added in an amount of, for example, 0.01 to 20% by mass, preferably 0.05 to 10% by mass, more preferably 0.1 to 5% by mass, and even more preferably 0.2 to 1% by mass relative to the total mass of the triglycerides used as raw materials. In addition to the above catalysts, any co-catalyst may be used. The transesterification reaction is carried out, for example, under normal pressure or reduced pressure at the heating temperature described above for, for example, 0.5 to 50 hours, preferably 1 to 40 hours, more preferably 5 to 30 hours, and even more preferably 10 to 20 hours, with optional stirring. In this reaction step, the predetermined amount of catalyst may be added all at once, or the predetermined amount may be added in 2 to 30 increments, preferably 3 to 20 increments, and more preferably 5 to 15 increments. The catalyst may be added immediately after the step (a) or every 1 to 2 hours after the first catalyst addition.

[0030] (a) Preparation of oil and fat composition step II The method for producing the oil and fat composition prepared in step (a) of the present invention further includes a method for simultaneously and directly synthesizing an XXX triglyceride and an X2Y triglyceride, as shown below. That is, in this preparation step II, to obtain an XXX triglyceride and an X2Y triglyceride, the XXX triglyceride and the YYY triglyceride are not separately synthesized and transesterified, but rather the raw materials for producing both triglycerides (fatty acids or fatty acid derivatives and glycerin) are placed in, for example, a single reaction vessel and simultaneously and directly synthesized, and the production method therefor can be any of the following methods. (iv) a method of directly esterifying glycerin with a fatty acid X having a carbon number of X and a fatty acid Y having a carbon chain of y (direct ester synthesis); (v) a method of reacting glycerin with a fatty acid alkyl (e.g., fatty acid methyl and fatty acid ethyl) in which the carboxyl group of a fatty acid X having a carbon number of x and a fatty acid Y having a carbon chain of y is bonded to an alkoxyl group, under basic or acidic catalytic conditions (ester exchange synthesis using fatty acid alkyl); and (vi) a method of reacting glycerin with a fatty acid halide (e.g., fatty acid chloride and fatty acid bromide) in which the hydroxyl group of the carboxyl group of a fatty acid X having a carbon number of x and a fatty acid Y having a carbon chain of y is substituted with a halogen, under basic catalytic conditions (acid halide synthesis). The oil and fat composition of the present invention can be produced by any of the above-mentioned methods. However, from the viewpoint of ease of production, (iv) direct ester synthesis or (v) transesterification synthesis using a fatty acid alkyl is preferred, and (iv) direct ester synthesis is more preferred.

[0031] In the direct ester synthesis (iv) of the oil and fat composition of the present invention, Although the production method is not limited as long as the XXX triglycerides and X2Y triglycerides are in the desired range by mass %, a two-stage reaction is preferred to ensure that the desired triglycerides are produced in the system. That is, a preferred method is to react glycerin with a fatty acid X having x carbon atoms, which contains a fatty acid Y having y carbon atoms, in the first stage, and then add a fatty acid X having x carbon chain in the second stage and react to produce an oil and fat composition containing predetermined amounts of XXX triglycerides and X2Y triglycerides. In the first-stage reaction of a two-stage reaction, the total molar amount of fatty acid Y and fatty acid X, adjusted so that the X2Y triglyceride accounts for a desired mass % of all glycerides, is preferably 0.5 to 2.8 moles, more preferably 0.8 to 2.57 moles, and most preferably 1.1 to 2.2 moles per mole of glycerin. This ensures that all of the fatty acid Y is reliably esterified with glycerin, and ultimately ensures that the X2Y glyceride is produced in the system more reliably. The reaction temperature in the direct ester synthesis of the oil or fat composition of the present invention may be any temperature at which the water produced by the esterification reaction can be removed from the system, and is preferably 120° C. to 300° C., more preferably 150° C. to 270° C., and even more preferably 180° C. to 250° C. In particular, by carrying out the reaction at 180 to 250° C., X2Y triglycerides can be produced efficiently.

[0032] In the (iv) direct ester synthesis of the oil or fat composition of the present invention, a catalyst that promotes the esterification reaction may be used. Examples of the catalyst include acid catalysts and alkaline earth metal alkoxides. The amount of the catalyst used is preferably about 0.001 to 1% by mass based on the total mass of the reaction raw materials. In the (iv) direct ester synthesis of the oil or fat composition of the present invention, after the reaction, the catalyst and unreacted raw materials can be removed by known purification treatments such as water washing, alkaline deoxidation and / or deoxidation under reduced pressure, and adsorption treatment. Furthermore, the obtained reaction product can be further purified by decolorization and deodorization treatment.

[0033] (a) Preparation of oil and fat composition step III The oil-and-fat composition may be prepared by first preparing an oil-and-fat composition containing XXX triglycerides outside the range of 80 to 99% by mass and / or X2Y triglycerides outside the range of 20 to 1% by mass, and then further adding the XXX triglycerides or X2Y triglycerides to obtain an oil-and-fat composition containing 80 to 99% by mass of XXX triglycerides and 20 to 1% by mass of X2Y triglycerides (preparation of oil-and-fat composition by dilution).For example, an oil-and-fat composition containing 50 to 70% by mass of XXX triglycerides and 50 to 30% by mass of X2Y triglycerides may be prepared, and then a desired amount of XXX triglycerides may be added to obtain an oil-and-fat composition containing 80 to 99% by mass of XXX triglycerides and 20 to 1% by mass of X2Y triglycerides. Furthermore, the adjusting step III also includes a step of first preparing an oil or fat composition containing 80 to 99% by mass of XXX triglycerides and / or 1 to 20% by mass of X2Y triglycerides by the preparing step I or II, and then further adding XXX triglycerides or X2Y triglycerides to adjust the mass percentages of XXX triglycerides and X2Y triglycerides to fall within a more preferred range (preparation of a more suitable oil or fat composition by dilution).

[0034] (b) A step of obtaining the oil and fat composition in a molten state Prior to the step (d), if the oil and fat composition obtained in the step (a) is in a molten state when prepared, it is cooled as is without heating. However, if the oil and fat composition is not in a molten state when obtained, it is optionally heated to melt the triglycerides contained in the oil and fat composition, thereby obtaining a molten oil and fat composition. Here, the oil and fat composition is heated to a temperature equal to or higher than the melting point of the triglyceride contained in the oil and fat composition. The temperature is suitably a temperature at which the XXX triglyceride and X2Y triglyceride can be melted, in particular, a temperature at which the XXX triglyceride and X2Y triglyceride can be melted, for example, 70 to 200° C., preferably 75 to 150° C., and more preferably 80 to 100° C. Heating is suitably continued for, for example, 0.5 to 3 hours, preferably 0.5 to 2 hours, and more preferably 0.5 to 1 hour.

[0035] (d) A step of cooling the molten oil or fat composition to obtain a powdered oil or fat composition. The molten oil and fat composition obtained in the above step (a) or (b) is further cooled to form a powdered oil. Here, "cooling a molten oil-and-fat composition" means maintaining a molten oil-and-fat composition at a temperature lower than the melting point of the oil-and-fat composition. "A temperature lower than the melting point of the oil-and-fat composition" refers to, for example, a temperature 1 to 30°C lower than the melting point, preferably a temperature 1 to 20°C lower than the melting point, and more preferably a temperature 1 to 15°C lower than the melting point. The molten oil-and-fat composition is cooled, for example, when x is 8 to 10, by cooling so that the final temperature is preferably 10 to 30°C, more preferably 15 to 25°C, and even more preferably 18 to 22°C. When x is 11 or 12, for example, the final cooling temperature is preferably 30 to 40°C, more preferably 32 to 38°C, and even more preferably 33 to 37°C. At the above-mentioned final temperature, it is appropriate to leave the composition standing for, for example, preferably 2 hours or more, more preferably 4 hours or more, and even more preferably 6 hours to 2 days. In particular, when the following step (c) is not used, it may be necessary to leave the mixture to stand for, for example, 2 to 8 days, specifically 3 to 7 days, and more specifically about 6 days.

[0036] (c) Powder generation promotion process Furthermore, between the above steps (a) or (b) and (d), as an optional step (c) for accelerating powder production, the molten fat composition used in step (d) may be subjected to a seeding method (c1), a tempering method (c2), and / or a preliminary cooling method (c3). These optional steps (c1) to (c3) may be performed alone or in combination. Here, "between step (a) or (b) and step (d)" means during step (a) or (b), after step (a) or (b) but before step (d), and during step (d). The seeding method (c1) and the tempering method (c2) are methods for promoting powder production in the production of powdered fats and oils, in which a molten fat and oil composition is treated before being cooled to the final temperature in order to more reliably turn the molten fat and oil composition into a powder. The seeding method is a method for promoting powderization by adding a small amount of a core (seed) component to a molten oil / fat composition during cooling. Specifically, for example, a core (seed) component is prepared by adding, to the molten oil / fat composition obtained in step (b), preferably 80% by mass or more, more preferably 90% by mass or more, of XXX triglycerides having the same carbon number as the XXX triglycerides in the oil / fat composition. This core (seed) component is added in an amount of 0.1 to 1 part by mass, preferably 0.2 to 0.8 parts by mass, per 100 parts by mass of the molten oil / fat composition during cooling when the temperature of the molten oil / fat composition reaches, for example, a temperature of ±0 to +10°C, preferably +5 to +10°C, the final cooling temperature. This method promotes powderization of the oil / fat composition. The tempering method is a method of cooling a molten oil or fat composition by once cooling it to a temperature lower than the cooling temperature in step (d), for example, 5 to 20°C lower, preferably 100°C lower, before leaving it at the final cooling temperature. This method promotes powderization of the oil or fat composition by cooling to a temperature lower by 7 to 15°C, more preferably about 10°C, for preferably 10 to 120 minutes, more preferably about 30 to 90 minutes. (c3) The pre-cooling method is a method in which the molten fat or oil composition obtained in step (a) or (b) is pre-cooled at a temperature lower than the temperature at which the fat or oil composition was melted in step (a) or (b) but higher than the cooling temperature in step (d) before being cooled in step (d). The temperature higher than the cooling temperature in step (d) may be, for example, a temperature 2 to 40°C higher, preferably 3 to 30°C higher, more preferably 4 to 30°C higher, and even more preferably 5 to 10°C higher than the cooling temperature in step (d). The lower the pre-cooling temperature, the shorter the main cooling time at the cooling temperature in step (d). In other words, unlike the seeding method or tempering method, the pre-cooling method is a method that can promote powderization of the fat or oil composition by simply lowering the cooling temperature in stages, and is therefore highly advantageous for industrial production.

[0037] (e) A step of crushing the solid material to obtain powdered oils and fats. More specifically, the step of obtaining a powdered oil or fat by cooling in the step (d) may be carried out by a step (e) of pulverizing the solid obtained by cooling in the step (d) to obtain a powdered oil or fat. In more detail, first, an oil-and-fat composition containing the XXX triglyceride and the X2Y triglyceride is melted to obtain a molten oil-and-fat composition, which is then cooled to form a solid having voids whose volume is larger than that of the molten oil-and-fat composition. The solid oil-and-fat composition having voids can be crushed by applying a light impact, and the solid easily disintegrates into a powder. Here, the means for applying the light impact is not particularly specified, but a method of pulverizing (loosening) the material by applying light vibration (impact) such as shaking or sieving is simple and preferable.

[0038] The content of (A) powdered oil or fat is from 8% to 62% by mass, preferably from 10% to 60% by mass, more preferably from 15% to 55% by mass, even more preferably from 20% to 50% by mass, and even more preferably from 25% to 45% by mass, relative to the total mass of the powder cosmetic. If the content of powdered oil or fat is within the above range, many of the properties of the powder cosmetic during use (particularly the melting sensation, cooling sensation, skin care effects, and makeup effects) will be good.

[0039] (B) Powdered ingredients (excluding (A) powdered oils and fats) The (B) powder component (excluding (A) powdered oils and fats) is not particularly limited, and conventionally known powder components for cosmetics can be used. Examples of powder components include silica, mica, talc, synthetic phlogopite, glass (borosilicate glass, soda-lime glass, etc.), lauroyl lysine, synthetic phlogopite iron, cellulose powder, resin powder, titanium oxide, iron oxide, tar dyes, and metal soaps. These powder components may be used alone or in combination of two or more.

[0040] The (B) powder component preferably contains (B1) an oil-absorbing powder and (B2) a metal soap, and may further contain (B3) another powder other than the (B1) oil-absorbing powder and (B2) metal soap. By containing both the (B1) oil-absorbing powder and the (B2) plate-like powder in a powder cosmetic, they are easily dispersed uniformly in the cosmetic, and many of the properties of the powder cosmetic during use (particularly the melting sensation in use and the makeup effect) become good.

If the oil absorption of the oil-absorbing powder is within the above range, many of the properties of the powder cosmetic when in use (particularly the melting feel, cooling sensation, skin care effect, and makeup effect) will be good. The oil absorption of the oil-absorbing powder can be measured in accordance with JIS K5101-13-2 (boiled linseed oil method).

[0042] The oil-absorbing powder preferably has a specific surface area of ​​100 m 2 / g or more, more preferably 200m 2 / g or more, and more preferably 300m 2 / g or more, and 1000m 2 / g or less, and 2 If the specific surface area of ​​the oil-absorbing powder is within the above range, many of the properties of the powder cosmetic when in use (particularly the melting sensation when in use, the cooling sensation, the skin care effect, and the makeup effect) will be good. In the present invention, the specific surface area of ​​the oil-absorbing powder can be calculated by measuring the amount of nitrogen adsorbed to the powder at a temperature of 77 K and analyzing it by the BET method. As a measuring instrument, for example, OMNISORP manufactured by Beckmann Coluter can be used.

[0043] The average particle size of the oil-absorbing powder is preferably 0.1 to 20 μm, more preferably 1 to 15 μm, and even more preferably 3 to 10 μm. When the average particle size of the oil-absorbing powder is within the above range, many of the properties of the powder cosmetic when in use (particularly the melting sensation when in use, the cooling sensation, the skin care effect, and the makeup effect) become good. In the present invention, the average particle size of the oil-absorbing powder is a value measured as the volume average particle size (D50) using a laser diffraction / scattering particle size distribution analyzer (MT3300EXII; manufactured by Microtrack Bell). The shape of the oil-absorbing powder is not particularly limited, but is preferably spherical.

The fatty acids used as raw materials for metal soaps preferably have 12 to 22 carbon atoms, and examples thereof include lauric acid, myristic acid, myristoleic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, arachic acid, behenic acid, erucic acid, hydroxystearic acid, and epoxystearic acid, with myristic acid being preferred. Metals that can be used as raw materials for metal soaps include magnesium, zinc, aluminum, calcium, and the like, with magnesium, zinc, and calcium being preferred, and magnesium being more preferred. Examples of metal soaps include magnesium myristate, zinc myristate, calcium myristate, aluminum myristate, zinc stearate, and zinc oleate, with magnesium myristate, zinc myristate, and calcium myristate being preferred, and magnesium myristate being more preferred.

The aspect ratio of the plate-shaped powder of metal soap is preferably 1.0 or more and 2.0 or less, more preferably 1.0 or more and 1.6 or less, and even more preferably 1.0 or more and 1.5 or less. In the present invention, the aspect ratio of the powder is expressed by the following formula (1), that is, it corresponds to the value obtained by dividing the major axis diameter of the powder by the minor axis diameter (=major axis diameter / minor axis diameter). Aspect ratio = powder major axis diameter (μm) / powder minor axis diameter (μm) Equation (1) The closer the aspect ratio is to 1.0, the closer the powder shape is to a square or circle. If the aspect ratio is within the above range, the spreadability on the skin is improved and the usability is excellent. The "major axis diameter" of a powder is the length of the major axis of the powder, more specifically, the width of the powder at the maximum distance between two parallel lines sandwiching the powder. The "minor axis diameter" of a powder is the length of the minor axis of the powder, more specifically, the width of the particle measured on a line passing through the midpoint of the major axis and perpendicular to the major axis. The average thickness of the powder is preferably 250 to 600 nm, more preferably 280 to 450 nm, and even more preferably 300 to 450 nm. The average thickness of the powder is the average value obtained by measuring the side lengths of 10 powder particles, with the largest surface of the powder being the front. The average thickness of the powder is a value measured based on a two-dimensional projection image of the powder (more specifically, an SEM photograph).
