Description

Makeup cosmetics

[0001] This invention relates to makeup cosmetics.

[0002] Emulsified cosmetics are a dosage form that has been used for topical skin preparations and are used not only in skincare cosmetics but also in makeup cosmetics. In recent years, there has been a demand for a glossy finish in makeup cosmetics, and by adding shine to the skin and lips, a healthier appearance can be achieved.

[0003] A glossy finish can be achieved using powders or oils. For example, while the gloss from pearl powders can be controlled by adjusting the particle size, it can sometimes lack a natural appearance. Therefore, there is a need for a method that provides a more natural gloss using oils.

[0004] As a technique for imparting gloss using oils, for example, Patent Document 1 discloses a solid emulsion cosmetic in which a high refractive index silicone oil, such as methylphenyl silicone including diphenylsiloxyphenyl trimethicone, is held inside a (dimethicone / phenylvinyl dimethicone) crosspolymer. Although this solid emulsion cosmetic is excellent in imparting gloss and its persistence, it contains a large amount of high refractive index silicone oil, such as methylphenyl silicone, at 4% by mass or more in order to impart gloss, so when sweat or tears come into contact with the cosmetic film over time, a phenomenon such as bleeding of the cosmetic film may occur. On the other hand, if the amount of high refractive index silicone oil is included in an amount sufficient to reduce bleeding, there is a problem that the cosmetic does not spread smoothly when applied to the skin.

[0005] As a way to solve this problem, for example, Patent Document 2 describes a method that uses a specific silicone to impart gloss to the application area, while also providing excellent gloss retention, smooth application, and reduced bleeding. However, Patent Document 2 suffers from poor adhesion between the skin and the cosmetic, or between new cosmetic applied on top of existing cosmetic on the skin, resulting in poor gloss retention and poor adhesion of the cosmetic to the skin. This also leads to the problem of makeup easily smudging when sweat is wiped from the skin with a handkerchief.

[0006] Japanese Patent Publication No. 2011-231102 Japanese Patent Publication No. 2018-203624

[0007] In view of the above problems, the present invention aims to provide a makeup cosmetic that provides excellent shine to the skin, adheres well even when layered, spreads smoothly on the skin, and maintains its effects such as resistance to creasing and shine even when rubbed with a handkerchief or the like.

[0008] In order to solve the above problems, the inventors diligently conducted research and found that the above problems could be solved by combining two specific types of isoparaffin, a pigment powder, and a nonionic surfactant in specific mass ratios, thus completing the present invention.

[0009] In other words, the present invention is a makeup cosmetic comprising (A) 0.1% to 15% by mass of isoparaffin having an average number of carbon atoms of 50 to 250, (B) 0.1% to 30% by mass of isoparaffin having an average number of carbon atoms of 20 to 24, (C) 10% to 55% by mass of pigment powder, and (D) 0.1% to 10% by mass of a nonionic surfactant, wherein the mass ratio of component (A) to component (B) ((A) / (B)) is 1 / 20 to 3 / 2.

[0010] In the makeup cosmetic composition of the present invention, component (C) may be one or more selected from extender pigments, coloring pigments, and luminosity pigments.

[0011] According to the present invention, the makeup cosmetic provides excellent shine to the skin, adheres well even when layered, spreads smoothly on the skin, and maintains its effects such as resistance to creasing and shine even when rubbed with a handkerchief or the like.

[0012] The embodiments of the present invention will be described below, but the present invention is not limited to the embodiments described herein and can be modified in various ways without departing from the spirit of the invention.

[0013] The terms used herein shall be interpreted based on the general understanding of those skilled in the art in fields such as organic chemistry, cosmetic chemistry, and pharmacy, but the following definitions of terms take precedence over the general understanding. "Skin" means the skin and its appendages (e.g., nails) of the entire body, including the face, such as the cheeks, forehead, chin, nose, eyelids, lips, neck, hands, nails, décolleté, arms, and legs. "Makeup cosmetics" as used herein may be applied to the skin, and especially to the skin of the face. "Gloss" means a texture that reflects light and appears radiant, and includes glossiness, smoothness, and moisture. "Smudging" means a state of makeup breakdown in which cosmetics lift off the skin due to sebum, sweat, friction, dryness, or insufficient adhesion to the skin, accumulating in pores and wrinkles, bleeding, becoming uneven, or the makeup film cracking.

[0014] Each upper and lower limit described stepwise in this specification may be the upper or lower limit of any combination of numerical ranges. Furthermore, values ​​explicitly stated in this specification or derived from such descriptions may also be the upper or lower limits of numerical ranges. For example, if there is a description of "an arithmetic sequence of numbers between 1 and 5 with a common difference of 1," then not only the explicitly stated 1 and 5, but also 2, 3, and 4 derived from that description may be the upper or lower limits of the numerical range. In the case of integer values ​​described in this specification, the first decimal place is rounded. In the case of decimal values ​​(including pure decimals and mixed decimals), the nth decimal place is rounded to the (n+1)th decimal place. For example, 5.1 is rounded to the second decimal place, and 0.10 is rounded to the third decimal place.

[0015] <Makeup Cosmetics> The makeup cosmetics of the present invention contain at least component (A), component (B), component (C), and component (D). Each component is described below.

[0016] [Component (A)] Component (A) used in the present invention is an isoparaffin with an average carbon number of 50 or more and 250 or less. This isoparaffin is a mixture of long-chain hydrocarbons having side chains, and is usually obtained by hydrogenating a polymer of isobutene and n-butene. Examples of such components include those generally classified as "heavy liquid isoparaffins" in the cosmetics field.

[0017] The upper limit of the average carbon number of isoparaffin is 250, preferably 230, more preferably 210, and particularly preferably 190. The lower limit is 50, preferably 60, more preferably 70, and particularly preferably 80. The range of the average carbon number of isoparaffin is constructed by combining numerical values ​​in an arithmetic progression with a tolerance of 10 within the range of 50 to 250, for example, 50 to 250, 60 to 230, 70 to 210, and 80 to 190. If the average carbon number is less than 50, the persistence of effects such as wrinkle prevention and gloss may be poor. On the other hand, if the average carbon number exceeds 250, the spreadability on the skin may be poor.

[0018] The average carbon number in this specification is a value derived using gel permeation chromatography (GPC). For example, it can be measured under the following conditions: [Measurement conditions] Apparatus: HLC-8220GPC manufactured by Tosoh Corporation Column: Shodex® GPC LF-804 manufactured by Resonaq Corporation Standard substance: Polystyrene Eluent: THF (tetrahydrofuran) Flow rate: 1.0 ml / min Column temperature: 40°C Detector: RI (differential refractive index detector)

[0019] The isoparaffin in component (A) has an upper limit of kinematic viscosity of 10,000 mm at 98°C. ２ It is preferable that it be / s, and 7500 mm ２ It is more preferable that it be / s, 5000 mm ２ It is particularly preferable that the kinematic viscosity is 100 mm² / s. Also, the lower limit of the kinematic viscosity at 98°C is 100 mm². ２ It is preferable that it be / s, and 300 mm ２ It is more preferable that it be / s, 800 mm ２ / s is particularly preferable. The range of kinematic viscosity at 98°C is 100 mm ２ / s to 10000 mm ２ / s, and is formed by combining numerical values of an arithmetic sequence with a tolerance of 100 mm ２ / s. Examples include 100 mm ２ / s to 10000 mm ２ / s, 300 mm ２ / s to 7500 mm ２ / s, 800 mm ２ / s to 5000 mm ２ / s.

[0020] In the present specification, the kinematic viscosity of isoparaffin and the following volatile oils is a value measured by a method in accordance with JIS K 2283:2000, and can be measured, for example, using an automatic viscosity measuring apparatus (model VMC-252, manufactured by Rigosha Co., Ltd.) with an Ubbelohde viscometer (viscometer No. 2) at the measurement temperature.

[0021] Specific commercial products of component (A) include "Parleam 18" (average carbon number: 72, kinematic viscosity (mm ２ / s, 98°C) = 300), "Parleam 24" (average carbon number: 96, kinematic viscosity (mm ２ / s, 98°C) = 800), "Parleam 46" (average carbon number: 184, kinematic viscosity (mm ２ / s, 98°C) = 4700) (all manufactured by NOF CORPORATION). As component (A), one or two or more selected from these isoparaffins having different average carbon numbers can be used. Note that "Parleam" is a registered trademark of NOF CORPORATION.

[0022] Component (A) can be obtained by synthesis, for example, as follows. First, a mixed gas of isobutene and n-butene can be treated by a known method, for example, cationic polymerization using a catalyst, to obtain a polymer. Subsequently, after hydrogenating the obtained polymer to obtain a polymer hydride, component (A) can be obtained through purification steps such as adsorption treatment and distillation. As component (A), one or two or more selected from these isoparaffins having different average carbon numbers can be used.

[0023] The content of component (A) described above has an upper limit of 15% by mass, preferably 12% by mass, more preferably 10% by mass, and even more preferably 5% by mass, with a lower limit of 0.1% by mass, preferably 0.5% by mass, and more preferably 1% by mass, relative to the total amount of makeup cosmetics (100% by mass, the same applies hereinafter). The range of the content of component (A) is composed of a combination of arithmetic values ​​with a tolerance of 0.1% by mass within the range of 0.1% by mass or more and 15% by mass or less relative to the total amount of makeup cosmetics, for example, 0.1% by mass or more and 15% by mass or less, 0.5% by mass or more and 12% by mass or less, 1% by mass or more and 10% by mass or less, and 1% by mass or more and 5% by mass or less. If the content of component (A) is less than 0.1% by mass, the persistence of effects such as creasing prevention and gloss may be poor, and if it exceeds 15% by mass, the spreadability on the skin may be poor.

[0024] [Component (B)] Component (B) used in the present invention is an isoparaffin having an average carbon number of 20 or more and 24 or less. This isoparaffin is a mixture of medium-chain hydrocarbons having side chains, and is usually obtained by hydrogenating a polymer of isobutene and n-butene. Examples of such components include those generally classified as "liquid isoparaffins" in the cosmetics field.

[0025] If the average carbon number is less than 20, volatility increases, which can lead to poorer durability of effects such as wrinkle prevention and gloss. On the other hand, if the average carbon number exceeds 24, the ease of application and spreadability on the skin may be reduced.

[0026] The isoparaffin in component (B) has an upper limit of kinematic viscosity of 100 mm at 37°C. ２ It is preferable that it be / s, and 75 mm ２ It is more preferable that it be / s, 50 mm ２ It is particularly preferable that the kinematic viscosity at 37°C be 8 mm. ２ It is preferable that it be / s, 9 mm ２ It is more preferable that it be / s, 10 mm ２ It is particularly preferable that the kinematic viscosity is / s. The range of kinematic viscosity at 37°C is 8 mm ２ / s or more 100mm２ / s with a tolerance of 1 mm within the range below ２ / s constituted by combining arithmetic sequence values, for example, 8 mm ２ / s or more and 100 mm ２ / s or less, 9 mm ２ / s or more and 75 mm ２ / s or less, 10 mm ２ / s or more and 50 mm ２ / s or less.

[0027] Component (B) can be obtained by synthesis, for example, as described below. First, a mixed gas of isobutene and n-butene can be treated by a known method, for example, cationic polymerization using a catalyst, to obtain a polymer. Subsequently, after hydrogenating the obtained polymer to obtain a hydrogenated polymer, component (B) can be obtained through purification steps such as adsorption treatment and distillation. As component (B), one or more kinds selected from these isoparaffins having different average carbon numbers can be used.

[0028] As specific commercial products of component (B), "Parelm EX" (average carbon number: 20, kinematic viscosity (mm ２ / s, at 37°C) = 11), "Parelm 6" (average carbon number: 24, kinematic viscosity (mm ２ / s, at 37°C) = 20), (both manufactured by NOF Corporation), and the like can be mentioned. As component (B), one or more kinds selected from these isoparaffins having different average carbon numbers can be used.

[0029] The content of the component (B) has an upper limit of 30% by mass, preferably 20% by mass, more preferably 10% by mass, still more preferably 5% by mass, and a lower limit of 0.1% by mass, preferably 0.5% by mass, more preferably 1% by mass, relative to the total amount of the makeup cosmetic. The content range of the component (B) is formed by combining values of an arithmetic progression with a common difference of 1% by mass within the range of 0.1% by mass to 30% by mass (inclusive) relative to the total amount of the makeup cosmetic. Examples include 0.1% by mass or more and 30% by mass or less, 0.5% by mass or more and 20% by mass or less, 1% by mass or more and 10% by mass or less, and 1% by mass or more and 5% by mass or less. When the content of the component (B) is less than 0.1% by mass, spreadability on the skin may be poor, and when it exceeds 30% by mass, the persistence of effects such as caking prevention and gloss may be deteriorated.

[0030] [Component (C)] The component (C) used in the present invention is a pigment powder, and any pigment powder used in ordinary cosmetics can be used. For example, extender pigments, colored pigments, luminous pigments and the like can be used. Component (C) may be one or more selected from the above.

[0031] Examples of extender pigments include inorganic extender pigments such as magnesium silicate, aluminum silicate, talc, sericite, mica, synthetic fluorophlogopite, glass powder, phlogopite, kaolin, clay, bentonite, hectorite, zeolite, bismuth oxychloride, zirconium oxide, magnesium oxide, aluminum oxide, calcium sulfate, barium sulfate, magnesium sulfate, calcium carbonate, magnesium carbonate, and composite powders thereof. Among these, talc, mica, kaolin and clay are preferred, and talc is particularly preferred.

Furthermore, composites of these coloring pigments and composite pigments combining these coloring pigments with pearl pigments are also possible. Examples of pearl pigments include natural or synthetic inorganic powders such as mica, phlogopite, talc, silica, sericite, glass, kaolin, bismuth oxychloride, cerium oxide, calcium sulfate, barium sulfate, magnesium sulfate, and plate-shaped alumina powder. Specific examples of composite pigments include titanium dioxide-coated mica, iron oxide-coated mica, iron oxide-coated titanium mica, iron oxide-coated synthetic fluorphlogopite, chromium oxide-coated titanium mica, titanium dioxide-coated glass powder, iron oxide-coated glass powder, titanium dioxide-encapsulated glass powder, and iron oxide-encapsulated glass powder, with titanium dioxide-coated mica being preferred. Among these coloring pigments, metal oxides are preferred, with one or more selected from titanium dioxide, zinc oxide, yellow iron oxide, black iron oxide, and red iron oxide being more preferred, and one or more selected from titanium dioxide, yellow iron oxide, black iron oxide, and red iron oxide being even more preferred.

[0033] As luminous pigments, for example, plate-like powders coated with a coloring agent or film rolls cut into arbitrary shapes can be used. Examples of plate-like powders include mica, synthetic fluorphlogopite, glass, silica, and alumina, and examples of coloring agents include titanium dioxide, iron oxide, silicon dioxide, Prussian blue, chromium oxide, tin oxide, chromium hydroxide, gold, silver, carmine, and organic pigments. Examples of film rolls cut into arbitrary shapes include polyethylene terephthalate / polymethyl methacrylate laminated powder, polyethylene terephthalate / aluminum vapor-deposited powder, and polyethylene terephthalate / gold vapor-deposited laminated powder. Furthermore, as luminous pigments, organic powders such as polyethylene powder, polypropylene powder, polymethyl methacrylate powder, nylon powder, polytetrafluoroethylene powder, silicone powder, silicone rubber powder, silk powder, urethane powder, cellulose powder, starch powder, and polyfluoroethylene can be used; inorganic powders such as silica, magnesium carbonate, and calcium carbonate; acylated lysine powders such as lauroyl lysine; and metal soap powders, which are metal salts of higher fatty acids, can be used.

[0034] The pigment powder of component (C) can be used as is, or it can be used after being hydrophobized by conventional methods. Examples of hydrophobization treatments include surface treatments such as fluorine compound treatment, silicone treatment, alkyl treatment, alkylsilane treatment, metal soap treatment, water-soluble polymer treatment, amino acid treatment, acylated amino acid treatment, lecithin treatment, organic titanate treatment, polyol treatment, acrylic resin treatment, methacrylate resin treatment, and urethane resin treatment.

[0035] As for the hydrophobic treatment, from the viewpoint of spreading quickly and evenly when applied to the skin, a hydrophobic treatment using one or more selected from silicone treatment, amino acid treatment, and acylated amino acid treatment is preferred, and a hydrophobic treatment using one or more selected from amino acid treatment and acylated amino acid treatment is more preferred. Examples of amino acids used in amino acid treatment include proline, hydroxyproline, alanine, glycine, sarcosine, lysine, aspartic acid, and glutamic acid, and their salts are also included. Furthermore, the fatty acids constituting the acyl group of the acylated amino acids used in acylated amino acid treatment are preferably fatty acids with 1 to 23 carbon atoms, more preferably fatty acids with 8 to 20 carbon atoms, and among these, stearoyl glutamic acid, lauroyl aspartic acid, dilauroyl glutamic acid lysine, and lauroyl lysine are even more preferred. Examples of salts of these include salts of Na, Ca, Al, Mg, Zn, Zr, and Ti. Specifically, pigment powders hydrophobized with disodium stearoyl glutamate, sodium lauroyl aspartate, etc. are preferred because they offer good adhesion to the skin, a uniform finish, and a non-powdery feel. Among these, pigment powders hydrophobized with disodium stearoyl glutamate are more preferred. When using a pigment powder of component (C) that has been hydrophobized, the content of component (C) in the makeup cosmetic refers to the mass including the compound used for hydrophobization.

[0036] The average particle size of component (C) is not particularly limited, but the upper limit is preferably 200 μm, more preferably 150 μm, particularly preferably 100 μm, even more preferably 50 μm, and even more preferably 30 μm, while the lower limit is preferably 0.01 μm, more preferably 0.05 μm%, particularly preferably 0.1 μm, even more preferably 0.2 μm, and even more preferably 0.3 μm. The range of the average particle size of component (C) is constructed by combining numerical values ​​in an arithmetic progression with a tolerance of 0.01 μm within the range of 0.01 μm to 200 μm, for example, 0.01 μm to 200 μm, 0.05 μm to 150 μm, 0.1 μm to 100 μm, 0.2 μm to 50 μm, 0.2 μm to 30 μm, and 0.3 μm to 30 μm. In this specification, "average particle diameter" refers to the median diameter D50 obtained by observing the surface condition using a scanning electron microscope (JEOL Ltd., JSM-7800F PRIME) and measuring it with an image analysis device (LUZEX®, NIRECO Corporation), and represents the median value of the major axis of the particles.

[0037] The content of component (C) described above has an upper limit of 55% by mass, preferably 45% by mass, more preferably 30% by mass, and a lower limit of 10% by mass, preferably 15% by mass, and more preferably 20% by mass, relative to the total amount of makeup cosmetics. The range of the content of component (C) is composed of a combination of arithmetic progression values ​​with a tolerance of 1% by mass, within the range of 10% by mass to 55% by mass, relative to the total amount of makeup cosmetics. Examples include 10% to 55% by mass, 15% to 45% by mass, and 20% to 30% by mass. When the content of component (C) is within the above range, the powdery feel of the finished product is suppressed, and a uniform finish is obtained. If the content of component (C) is less than 10% by mass, the persistence of effects such as creasing prevention and gloss may be poor, and if it exceeds 55% by mass, the spreadability on the skin may be poor.

[0038] [Component (D)] Component (D) used in the present invention is a nonionic surfactant, and those commonly used in cosmetics can be used. Examples include sorbitan fatty acid esters such as sorbitan monooleate, sorbitan monoisostearate, sorbitan sesquistearate, and sorbitan sesquioleate; polyhydric alcohol fatty acid esters such as glycerin fatty acid esters, diglycerin fatty acid esters, and propylene glycol fatty acid esters; polyoxyethylene fatty acid esters such as polyoxyethylene castor oil, polyoxyethylene hydrogenated castor oil, polyoxyethylene hydrogenated castor oil fatty acid esters, and polyethylene glycol fatty acid esters; ether-type nonionic surfactants such as alkyl glyceryl ethers, alkyl polyglyceryl ethers, polyoxyethylene alkyl ethers, polyoxyethylene alkyl ether fatty acid esters, and polyoxyethylene alkylamines; and silicone-based surfactants such as polyether-modified silicones (e.g., polyoxyethylene methylpolysiloxane copolymer, poly(oxyethylene oxypropylene) methylpolysiloxane copolymer, etc.), polyglycerin-modified silicones, alkyl-modified polyether-modified silicones, and alkyl chain-comodified polyether-modified silicones. Component (D) can be one or more selected from these. Of these, from the viewpoint of improving the dispersibility of water and water-soluble components in oil, one or more nonionic surfactants selected from sorbitan fatty acid esters, polyhydric alcohol fatty acid esters, and polyether-modified silicones are preferred as nonionic surfactants that are liquid at 25°C.

[0039] The nonionic surfactant of component (D) is preferably a lipophilic nonionic surfactant from the viewpoint of improving the dispersibility of water and water-soluble components in oil. For example, a nonionic surfactant with an HLB value of preferably 2 to 7, more preferably 3 to 6, and even more preferably 4 to 6. The HLB (Hydrophilic-Lipophilic Balance) value indicates the molecular weight of the hydrophilic group portion in the total molecular weight of the surfactant and is determined by Griffin's formula. Furthermore, when composed of two or more nonionic surfactants, the HLB value of the mixed surfactant is determined as follows: The HLB value of the mixed surfactant is the phase-averaged value of the HLB values ​​of each nonionic surfactant based on their blending ratio. Mixed HLB value = Σ(HLBx × Wx) / ΣWx HLBx indicates the HLB value of nonionic surfactant X. Wx represents the mass (g) of nonionic surfactant X having an HLBx value.

[0040] As the nonionic surfactant for component (D), commercially available products can be used. For example, as sorbitan monooleate, nonionic OP-80R (HLB value: 4.3) (manufactured by NOF Corporation) can be used, as sorbitan monoisostearate, Span 120-LQ (HLB value: 4.7) (manufactured by Croda Corporation) can be used, as a glycerin fatty acid ester, monoglyceryl stearate, monoglycerin MB (HLB value: 5.5) (manufactured by NOF Corporation) can be used, and polyoxyethylene methylpoly Examples of siloxane copolymers include KF-6015 (HLB value: 4.5), KF-6017 (HLB value: 4.5), KF-6028 (HLB value: 4) (all manufactured by Shin-Etsu Chemical Co., Ltd.), SH3775M (HLB value: 5) (manufactured by Dow Toray Industries, Inc.), and poly(oxyethylene / oxypropylene)methylpolysiloxane copolymers include KF-6012 (HLB value: 7) (manufactured by Shin-Etsu Chemical Co., Ltd.), DOWSIL Examples include BY 22-008 M (HLB value: 2), DOWSIL BY 25-337 (HLB value: 3), DOWSIL ES-5226 (HLB value: 2), and DOWSIL ES-5227 (HLB value: 2) (all manufactured by Dow Toray Industries, Inc., "DOWSIL" is a registered trademark). Examples of alkyl-modified polyether-modified silicones include KF-6038 (HLB value: 3) (manufactured by Shin-Etsu Chemical Co., Ltd.) and ABIL® EM 90 (HLB value: 5) (manufactured by Evonik).

[0041] The content of component (D) described above has an upper limit of 10% by mass, preferably 8% by mass, more preferably 5% by mass, and a lower limit of 0.1% by mass, preferably 0.5% by mass, and more preferably 1% by mass, relative to the total amount of makeup cosmetics. The range of the content of component (D) is composed of a combination of arithmetic progression values ​​with a tolerance of 0.1% by mass, within the range of 0.1% by mass or more and 10% by mass or less, relative to the total amount of makeup cosmetics. Examples include 0.1% by mass or more and 10% by mass or less, 0.5% by mass or more and 8% by mass or less, and 1% by mass or more and 5% by mass or less. When the content of component (D) is within the above range, the dispersibility of water and water-soluble components in oil is enhanced. If the content of component (D) is less than 0.1% by mass, deemulsification and separation may occur, and if it exceeds 10% by mass, the persistence of effects such as creasing prevention and gloss, and the spreadability on the skin may be inferior.

[0042] The total content of components (A) to (D) in the makeup cosmetic has an upper limit of preferably 80% by mass, more preferably 70% by mass, and even more preferably 65% ​​by mass, and a lower limit of preferably 15% by mass, more preferably 20% by mass, and even more preferably 25% by mass. The range of the total content is constructed by combining numerical values ​​in an arithmetic progression with a tolerance of 1% by mass within the range of 15% by mass or more and 80% by mass or less with respect to the total amount of the makeup cosmetic, for example, 15% by mass or more and 80% by mass or less, 20% by mass or more and 70% by mass or less, and 25% by mass or more and 65% by mass or less.

[0043] In the present invention, the mass ratio of component (A) to component (B) ((A) / (B)) has an upper limit of 3 / 2, preferably 5 / 4, more preferably 1 / 1, and a lower limit of 1 / 20, preferably 3 / 20, more preferably 1 / 4. The range of the mass ratio ((A) / (B)) is constructed by combining numerical values ​​in an arithmetic progression with a tolerance of 1 / 20 within the range of 1 / 20 or more and 3 / 2 or less. Examples include 1 / 20 or more and 3 / 2 or less, 3 / 20 or more and 5 / 4 or less, and 1 / 4 or more and 1 / 1 or less. If the mass ratio ((A) / (B)) is less than 1 / 20, the persistence of effects such as wrinkle prevention and gloss may be poor, and if the mass ratio ((A) / (B)) exceeds 3 / 2, the spreadability on the skin may be poor.

[0044] [Water] In addition to the above-mentioned components (A) to (D), the makeup cosmetic composition of the present invention contains water. Examples of water include purified water such as distilled water or ion-exchanged water, and tap water. Among these, purified water such as distilled water or ion-exchanged water is preferred.

[0045] The water content, relative to the total amount of the makeup cosmetic, has an upper limit of preferably 85% by mass, more preferably 80% by mass, and even more preferably 75% by mass, and a lower limit of preferably 20% by mass, more preferably 25% by mass, and even more preferably 30% by mass. The range of water content is constructed by combining numerical values ​​in an arithmetic progression with a tolerance of 1% by mass within the range of 20% by mass or more and 85% by mass or less relative to the total amount of the makeup cosmetic, for example, 20% by mass or more and 85% by mass or less, 25% by mass or more and 80% by mass or less, and 30% by mass or more and 75% by mass or less.

[0046] The above-mentioned content of each component represents the content when the total content of all components constituting the makeup cosmetic is taken as 100% by mass. Furthermore, if multiple substances corresponding to each component exist in the composition, the content of each component in the composition refers to the total content of those multiple substances present in the composition.

Prior to the evaluation test, each panelist was trained in a preliminary evaluation test to ensure that their evaluation levels for each score were roughly consistent, thus preventing any discrepancies in evaluation criteria among the panelists.

[0065] (1) Shine Ten men and women aged 25 to 55 served as panelists. They took an appropriate amount of makeup in their palms, applied it to their skin, and spread it evenly. Afterwards, they evaluated the shine of their skin according to the following absolute evaluation criteria. The total score of each panelist's score was calculated, and based on that total score, they were evaluated on a three-level scale of "A", "B", and "C" according to the following evaluation criteria. An evaluation of "A" or "B" was considered a pass. <Absolute Evaluation Criteria> (Score): (Evaluation) 2: When the skin is perceived as shiny 1: When the skin is perceived as slightly shiny 0: When the skin is perceived as not shiny <Three-level evaluation based on total score> A: Total score is 14 to 20 points B: Total score is 7 to 13 points C: Total score is 6 points or less

[0066] (2) Adhesion when applied in multiple layers Ten men and women aged 25 to 55 served as panelists. They took an appropriate amount of makeup in their palms, applied it to their skin, and spread it. After one hour, they took an appropriate amount of makeup in their palms again, applied it to their skin, and spread it. The degree of adhesion to the skin at that time was evaluated according to the following absolute evaluation criteria. The total score of each panelist's score was calculated, and based on that total score, it was evaluated in three stages, "A", "B", and "C", according to the following evaluation criteria. An evaluation of "A" or "B" was considered a pass. <Absolute Evaluation Criteria> (Score): (Evaluation) 2: When the adhesion was felt 1: When the adhesion was felt to some extent 0: When the adhesion was felt to no extent <Three-stage evaluation based on the total score> A: Total score of 14 points or more and 20 points or less B: Total score of 7 points or more and 13 points or less C: Total score of 6 points or less

[0067] (3) Spreadability Ten men and women aged 25 to 55 served as panelists. They took an appropriate amount of makeup product in their palms, applied it to their skin, and spread it. The spreadability on the skin was evaluated according to the following absolute evaluation criteria. The total score of each panelist's score was calculated, and based on that total score, a rating of "A", "B", and "C" was given according to the following evaluation criteria. An "A" or "B" rating was considered a pass. <Absolute Evaluation Criteria> (Score): (Evaluation) 2: When the spreadability was felt to be very good 1: When the spreadability was felt to be good 0: When the spreadability was felt to be poor <Three-level evaluation based on total score> A: Total score of 14 or more and 20 or less B: Total score of 7 or more and 13 or less C: Total score of 6 or less

[0068] (4) Durability of the effect when friction is applied Ten men and women aged 25 to 55 served as panelists. They took an appropriate amount of makeup in their palms, applied it to their skin, and spread it. After that, they rubbed the applied area with a handkerchief and evaluated whether the makeup did not smudge, and whether the effects such as creasing prevention and shine were maintained, according to the following absolute evaluation criteria. The total score of each panelist's score was calculated, and based on that total score, it was evaluated in three stages, "A", "B", and "C", according to the following evaluation criteria. An evaluation of "A" or "B" was considered a pass. <Absolute evaluation criteria> (Score): (Evaluation) 2: When the durability was felt to be very good 1: When the durability was felt to be good 0: When the durability was felt to be poor <Three-stage evaluation based on the total score> A: Total score of 14 points or more and 20 points or less B: Total score of 7 points or more and 13 points or less C: Total score of 6 points or less

[0070]

[0071] The makeup products of Examples 1 to 11 were able to impart excellent luster to the skin, maintained a sense of adhesion even when layered, spread smoothly on the skin, and exhibited excellent persistence of effect even when rubbed.

[0072] In contrast, Comparative Examples 1 to 4 did not achieve sufficient performance. Comparative Example 1 did not contain component (A), so it lacked gloss, adhesion when applied in multiple coats, and durability of the effect when friction was applied. Comparative Example 2 did not contain component (B), so it did not spread well. Comparative Example 3 had a large mass ratio of component (A) to component (B) ((A) / (B)), so it did not spread well. Comparative Example 4 had a small mass ratio of component (A) to component (B), so it lacked gloss, adhesion when applied in multiple coats, and durability of the effect when friction was applied.

[0073] Next, an example of a makeup cosmetic formulation of the present invention (Formulation Example 1) is shown. This makeup cosmetic formulation also provides excellent shine to the skin, adheres well even when layered, spreads smoothly on the skin, and exhibits excellent persistence of effect even when rubbed. The mass ratio ((A) / (B)) is 3 / 7. The symbols for each component indicate the components listed in Table 1.
