Abstract
Description
[Technical Field]
[0001] The present invention relates to a solid powder cosmetic preparation. [Background technology]
[0002] Powder cosmetics, which are cosmetics blended with powder, are widely used as makeup cosmetics such as foundation, face powder, blush, eye shadow, eyebrow pencil, etc. Among these, many solid powder cosmetics that are molded into a solid form have been put on the market in terms of portability and texture.
[0003] Methods for molding solid powder cosmetics include the dry filling molding method, in which a powdered cosmetic base is filled into a container such as a metal plate and then pressurized, and the wet filling molding method, in which a solvent such as a volatile compound is added to the powdered cosmetic base to form a slurry, which is then filled into a container such as a metal plate and then molded by removing the solvent. The wet molding method is a commonly used molding method because it provides a moist feel when applied.
[0004] However, the wet filling method requires the addition of a solvent, which can pose environmental risks when using organic solvents, and when using water as a solvent, other ingredients may need to be blended to maintain bulk uniformity. For these reasons, the dry filling method is also widely used.
[0005] On the other hand, for solid powder cosmetics, suppressing caking during use (a phenomenon in which the surface of an applicator such as a cosmetic puff becomes hard and inaccessible after repeated use) is a very important quality item in terms of improving usability.
[0006] For example, in Patent Document 1, iron oxide, amorphous plate-like silica, and a kinematic viscosity of 10,000 mm 2 It is said that solid powder cosmetics containing hydrocarbon oils of 1 / s or more and oily ingredients that are paste-like at 25°C do not cause caking when used. [Prior art documents] [Patent documents]
[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-124839 Summary of the Invention [Problem to be solved by the invention]
[0008] After applying a solid powder cosmetic to the skin, the powder adheres to the skin, forming a cosmetic film and achieving the cosmetic effect of the powder. Therefore, for a solid powder cosmetic, adhesion of the cosmetic to the skin (excellent adhesion) is extremely important for achieving the cosmetic effect. Furthermore, it is difficult to achieve a moist feel when using a solid powder cosmetic obtained by the dry filling molding method compared to solid powder cosmetics obtained by the wet filling molding method.
[0009] In order to improve the moist feel and adhesion of the product, it is conceivable to incorporate a high-viscosity oil agent with high skin adhesion in the dry filling molding method. However, if the amount of high-viscosity oil agent incorporated is too high, the bonding strength between the powder particles becomes too strong, making caking more likely to occur.
[0010] Therefore, an object of the present invention is to provide a solid powder cosmetic produced using a dry filling molding method that can suppress caking and improve the feel of use, such as a moist feel and adhesiveness. [Means for solving the problem]

[0023] The solid powder cosmetic of the present invention can suppress caking while improving the feel of use, such as a moist feel and high skin adhesion. DETAILED DESCRIPTION OF THE INVENTION
[0024] Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to the following embodiments. In this specification, the range "X to Y" includes X and Y and means "X or more and Y or less." Furthermore, unless otherwise specified, operations and measurements of physical properties, etc. are performed under conditions of room temperature (20 to 25°C) and relative humidity of 45 to 55% RH.
[0025] The detailed mechanism by which the solid powder cosmetic of the present invention exhibits the above-mentioned effects is unknown, but is thought to be as follows: Note that the following mechanism is not intended to limit the technical scope of the present invention in any way.
[0026] As described above, increasing the amount of oil in a solid powder cosmetic can achieve a moist feel and improved adhesion, but caking is more likely to occur. Focusing on this point, the inventors conducted research into improving the feel of use while suppressing caking by investigating a range of oil content that is low. As a result, they discovered that by combining a solid oil and a liquid / paste oil, using a cosmetic base with a low content of both, and heating after dry-filling molding, it is possible to suppress caking while improving the feel of use, such as a moist feel and adhesion. In dry-filling molding, the powder and oil are mixed in a dry state, which tends to result in uneven coverage of the oil on the powder surface, making it difficult for the oil to exert its effects. On the other hand, by heating the molded product after dry-filling molding, (part of) the solid oil dissolves and is uniformly coated on the powder surface, which is thought to result in a moist feel of use and improved skin adhesion. Furthermore, if the powder is heated before dry-fill molding, the moist feel and improvement in adhesion are not sufficient. Heating the powder in a state where the powder particles are in close contact with each other during the filling molding makes it easier for the oil agent to coat the powder uniformly, so it is thought that heating the molded product after dry-fill molding is necessary.
[0027] In this specification, the term "solid powder cosmetic" refers to a solid cosmetic whose main component is powder (powder). Here, the term "main component" refers to a cosmetic whose main component is powder (powder) at 50% by mass or more.

Here, even when a metal soap is used as a surface treatment agent for the powder, the content of the component (A1) includes the amount of the surface treatment agent.
[0052] (B: solid oil at 25°C) Component (B) is an essential constituent element for providing a moist feel in use and improving adhesion.

In the present invention, from the viewpoints of moist feel and adhesion, it is preferable that component (C) contains an oil that is paste-like at 25°C (component (C1)), and it is more preferable that component (C) is a combination of an oil that is liquid at 25°C and an oil that is paste-like at 25°C (component (C1)). The use of component (C1) makes it easier for the oil to coat the powder particles than when only a liquid oil is used, and heating after filling and molding can increase the fluidity of the oil between the powder particles, making it easier for the oil to coat the powder surfaces more uniformly, which is thought to improve the feel and other aspects of use.
[0059] Component (C1) is an oil agent that is pasty at 25°C. Here, "paste-like at 25°C" refers to an oil-based component that exhibits high viscosity at 25°C and has a melting point above 25°C (preferably a melting point of 30°C or higher but lower than 60°C, more preferably 35 to 50°C, and even more preferably 35°C or higher but lower than 50°C). "Paste-like at 25°C" refers to, for example, a state in which the viscosity at 25°C is greater than 30,000 mPa·s but not greater than 500,000 mPa·s. The viscosity can be measured using a single-cylinder rotational viscometer, Vismetron Model VS-A1 (manufactured by Shibaura Systems Co., Ltd.), after leaving a sample at 25°C for one day.
[0060] Component (C1) is not particularly limited, but examples thereof include hydrocarbon oils such as petrolatum; di(octyldodecyl / phytosteryl / behenyl) lauroyl glutamate, phytosteryl isostearate, phytosteryl oleate, phytosteryl hydroxystearate, di(phytosteryl / isostearyl / cetyl / stearyl / behenyl) dilinoleate, phytosteryl macadamiate, phytosteryl butyrate, phytosteryl nonanoate, cholesteryl stearate, cholesteryl isostearate, cholesteryl hydroxystearate, phytosteryl caprylate / caprate, phytosteryl ricinoleate, cholesteryl oleate, dihydrocholesteryl oleate, cholesteryl branched fatty acids (C12-31), phytosteryl canola glycerides, phytosteryl rapeseed glycerides, phytosteryl macadamiate, macadamia glycerides Examples of suitable fatty acids include sterol fatty acid esters such as cholesteryl, dihydrocholesteryl macadamia nut oil fatty acid, phytosteryl sunflower seed oil fatty acid, phytosteryl rice bran oil fatty acid, and cholesteryl lanolinate; dipentaerythrityl hexa(hydroxystearate / stearic acid / rosinate) dipentaerythrityl hexahydroxystearate, dipentaerythrityl rosinate, and dipentaerythrityl tri-polyhydroxystearate; dimer acid esters such as phytosteryl / isostearyl / cetyl / stearyl / behenyl dimer dilinoleate, dimer dilinoleyl bis(behenyl / isostearyl / phytosteryl) dimer dilinoleate, and di(isostearyl / phytosteryl) dimer dilinoleate; and hydrogenated castor oil fatty acid esters such as hydrogenated castor oil isostearate and hydrogenated castor oil monohydroxystearate. These components (C1) may be used alone or in combination of two or more.Among these, from the viewpoint of usability and the like, component (C1) is preferably petrolatum and / or ester oil, more preferably at least one selected from the group consisting of petrolatum, dipentaerythritol fatty acid esters, and sterol fatty acid esters, even more preferably at least one selected from the group consisting of dipentaerythritol fatty acid esters and di(octyldodecyl / phytosteryl / behenyl) lauroyl glutamate, even more preferably dipentaerythritol fatty acid esters, and particularly preferably dipentaerythritol hexa(hydroxystearate / stearic acid / rosinate).
[0061] The content of component (C1) in the cosmetic is preferably 0.01 to 8 mass%, more preferably 0.05 to 5 mass%. A content above the lower limit makes it easier to obtain the effects of component (C1), such as a moist feel in use and adhesion, while a content below the upper limit is advantageous in terms of suppressing caking, and is therefore preferred.
[0062] An oil agent that is liquid at 25°C (hereinafter also referred to simply as liquid oil) refers to an oil that is liquid (has fluidity) at 25°C.

These liquid oils may be used alone or in combination.
[0063] In terms of the effects of component (C), the content of component (C) in the cosmetic is preferably 0.01% by mass or more, 0.1% by mass or more, 0.2% by mass or more, 0.25% by mass or more, 0.5% by mass or more, or 1% by mass or more. In terms of suppressing caking, the content of component (C) is preferably 9.9% by mass or less, 9.8% by mass or less, 9.5% by mass or less, or 9% by mass or less. The content of component (C) is preferably 0.01 to 9.9% by mass, 0.1 to 9.8% by mass, 0.2 to 9.5% by mass, 0.25 to 9.5% by mass, 0.25 to 9% by mass, 0.5 to 9% by mass, or 1 to 9% by mass.
[0064] In the present invention, the total content of components (B) and (C) in the cosmetic is 10% by mass or less. If the total content of components (B) and (C) in the cosmetic exceeds 10% by mass, caking becomes significantly more likely to occur. The total content of components (B) and (C) in the cosmetic may be less than 10% by mass, or 9.5% by mass or less. Furthermore, the total content of components (B) and (C) in the cosmetic is 0.5% by mass or more. If the total content of components (B) and (C) in the cosmetic is less than 0.5% by mass, the moist feel and adhesion are significantly reduced. It is more preferable that the total content of components (B) and (C) in the cosmetic is 0.8% by mass or more, or 1% by mass or more. The total content of component (B) and component (C) in the cosmetic is preferably 0.5 to 10 mass %, 0.8 mass % or more but less than 10 mass %, or 1 to 9.5 mass % in the cosmetic.
[0065] In the present invention, the mass ratio (B) / (C) of the content of component (B) to the content of component (C) is preferably 0.1 to 10, more preferably 0.3 to 8, even more preferably 0.5 to 5, and even more preferably 0.7 to 4, from the viewpoint of the feel when used.
[0066] (Dry filling molding) In dry-fill molding, a cosmetic base containing components (A) to (C) is mixed in the absence of a volatile solvent, and then filled into a container under pressure to form the product. In contrast, in wet-fill molding, a cosmetic base in a fluid slurry state is filled into a container. The cosmetic base flows during filling, which tends to result in a structure in which the powder is oriented in the direction of the flow. On the other hand, solid powder cosmetics formed by dry methods are thought to have random powder orientation. Furthermore, the present invention requires the use of solid oil, which is incompatible with the solvent used in wet methods, making it difficult to achieve a caking-inhibiting effect. Therefore, the structure of the cosmetic product obtained varies depending on the manufacturing method, and the resulting physical properties also differ (see Example 2 and Comparative Examples 6 and 7, described below).
[0067] Before dry filling, component (A), component (B), component (C) and any optional components can be mixed to obtain a powdery cosmetic base.
[0068] The order of addition of components (A), (B), and (C) when preparing the cosmetic base is not particularly limited. Components (A), (B), and (C) may be mixed all at once, or components (A) and (B) may be mixed and then component (C) may be added, or components (A) and (C) may be mixed and then component (B) may be added. Adding component (C) after mixing components (A) and (B) is preferred, as this allows for uniform mixing of components (A) and (B). In this case, it is preferable to mix component (B) with component (A) without heating it, from the perspective of uniform mixing. Furthermore, when adding component (C), it is preferable to heat component (B) to a temperature at which it melts, from the perspective of uniform mixing.
[0069] When mixing the powder (component (A)) with the oily components (component (B), component (C), and other optional components), a high-speed agitator / mixer such as a Henschel mixer can be used. The resulting mixture can be pulverized using a pulverizer, atomizer, or other grinder.
[0070] The powdered cosmetic base is filled into any container. Examples of the container include dish-shaped containers such as metal dishes and resin dishes. The filling temperature is usually room temperature, and the temperature at which filling is possible is, for example, 10 to 35°C. After filling, the cosmetic base is pressed into a solid form using a press or the like. The pressing pressure during pressing can be appropriately set to obtain an appropriate hardness. The hardness in this case is, for example, 3 or more. The hardness can be measured using an automatic constant pressure load machine (GS-610, manufactured by TECROCK) / digital rubber hardness tester (GSD-706K, manufactured by TECROCK).
[0071] (heating) Heating is performed after the filling step. Heating before dry filling does not achieve the effects of the present invention. The heating temperature is preferably below the melting point of component (B) to suppress caking. By heating at a temperature below the melting point of component (B), components (B) and (C) do not completely melt, resulting in more uniform coating of the powder than when not heated. However, since the coating does not progress too far, it is thought that it is easier to achieve both a good feel when used and no caking. The heating temperature is, for example, preferably at least 5°C lower than the melting point of component (B), and may be at least 10°C lower. When multiple components (B) are used, the term "temperature lower than the melting point of component (B)" refers to a temperature lower than the melting point of the component (B) with the lowest melting point.
[0072] Specifically, the heating temperature is preferably 30 to 180° C., more preferably 40 to 150° C., and even more preferably 40 to 120° C., 45 to 100° C., 45 to 90° C., 45 to 80° C., 45 to 70° C., or 45 to 65° C. Heating within such a temperature range makes it easier to achieve both a pleasant feel in use and no caking.
[0073] The heating time is set appropriately taking into consideration the effects of the present invention, but is preferably 1 hour or more, and more preferably 3 to 24 hours. The heating means is preferably a means that heats the entire system, and is not particularly limited, but examples thereof include a thermostatic bath.
[0074] In addition to the above-mentioned components, the solid powder cosmetic of the present invention may contain optional components commonly used in cosmetics, such as emulsifiers, preservatives, antioxidants, cosmetic ingredients, antibacterial agents, fragrances, chelating agents (such as EDTA), ultraviolet absorbers, film-forming agents, and polyhydric alcohols, as appropriate, within the scope that does not impair the effects of the present invention.
[0075] In the solid powder cosmetic of the present invention, the water content is preferably 3% by mass or less, more preferably 1% by mass or less, and preferably substantially free of water. Here, "substantially free of water" means that the content of impurities is acceptable, for example, 0.1% by mass or less.
[0076] The solid powder cosmetic of the present invention can be used in makeup cosmetics such as foundation, face powder, face powder (white powder), concealer, eye color (eye shadow), eyeliner, eyebrow pencil, mascara, blush, lipstick, sunscreen cosmetics, and cosmetic base; skin care cosmetics such as body powder; and preferably, the cosmetic is a makeup cosmetic such as foundation, face powder, face powder, eye color, cosmetic base, sunscreen cosmetics, and blush, which are expected to exhibit the effects of the present invention more effectively, and more preferably, a foundation, face powder, or face powder, which have a large application area. The cosmetic can be used by applying it with the hands or fingers, or by impregnating a puff, sponge, or the like with the cosmetic. [Example]
[0077] The effects of the present invention will be explained using the following examples and comparative examples. In the examples, the terms "parts" and "%" may be used, but unless otherwise specified, they represent "parts by mass" or "% by mass." Furthermore, unless otherwise specified, each operation is carried out at room temperature (25°C). In the following examples, the "remaining amount" in the content (% by mass) means the amount that makes the total amount 100% by mass.
[0078] Examples 1 to 29 and Comparative Examples 1 to 7: Face powders were prepared according to the formulations shown in Tables 1 to 4 below.
[0079] (Manufacturing method) (1) Components (A), (A1) and (B) were mixed and stirred to obtain a mixture. (2) Components (C) and (C1) were heated and mixed, and then added to (1) and further mixed. (3) The mixture obtained in (2) was pulverized to obtain a powdered cosmetic base. (4) The powdered cosmetic base obtained in (3) is filled into a container (a resin dish (length 5 cm x width 4 cm x depth 1 cm)) in 10 g portions, and then compressed at 200 kg / cm by a dry filling molding method. 2 The molded product was press-molded at a pressure of 1000 kJ / cm. (5) The obtained pressed product was left to stand for 10 hours in a thermostatic oven set at the heating temperature shown in the table, and then removed from the thermostatic oven to obtain a solid powder cosmetic (face powder).
[0080] In Comparative Examples 6 and 7, face powders were produced by the wet filling molding method, in which 100 parts by mass of the cosmetic base obtained in (3) was mixed with the solvent (No. 20 purified water, No. 21 light liquid paraffin) in the amount shown in Table 4 to obtain a slurry composition, which was then filled into a mold and press-molded, followed by drying to remove the solvent, to obtain a solid powder cosmetic (face powder).
[0081] Evaluation method 1: Moist feeling when used Twenty cosmetic evaluation panel members were asked to use each face powder, and each panel member rated the "moisturizing feeling" using the following five-point scale, and the average score was calculated from the total scores of all panel members for each sample, and judged according to the following four-point scale. Moisturizing feeling was evaluated by applying each sample and assessing whether or not the skin felt moisturized. <5-point rating scale> [evaluation] Very good: 5 points Good: 4 points Average: 3 points Slightly poor: 2 points Defective: 1 point <4-level evaluation criteria> [Average score]:[Judgment] Over 4.5 points: A (Excellent) Over 4.0 points and under 4.5 points: B (Good) Over 3.0 points and under 4.0 points: C (passable) 3.0 points or less: D (not acceptable).
[0082] Evaluation method 2: Adhesion to the skin (adhesion) Twenty cosmetic evaluation panel members were asked to use each face powder, and each panel member rated and scored the "adhesion to the skin" using the absolute evaluation below on a 5-point scale. The average of the scores of all panelists for each sample was calculated and judged according to the 4-point rating scale below. Adhesion to the skin was evaluated by whether or not the powder did not fall off when each sample was applied to the skin and whether or not the cosmetic film felt to be adhering to the skin. <5-point rating scale> [evaluation] Very good: 5 points Good: 4 points Average: 3 points Slightly poor: 2 points Defective: 1 point <4-level evaluation criteria> [Average score]:[Judgment] Over 4.5 points: A (Excellent) Over 4.0 points and under 4.5 points: B (Good) Over 3.0 points and under 4.0 points: C (passable) 3.0 points or less: D (not acceptable).
[0083] Evaluation method 3: Absence of caking The surface of each sample was rubbed back and forth with a face powder puff 50 times in succession, and the surface condition of each sample was visually inspected. If caking (the surface of each sample solidified) occurred during the process, the puff was stopped and the number of times until caking occurred was recorded. The absence of caking was judged according to the following criteria. <Judgment criteria> (judgement) A: No caking even after 50 strokes B: Caking occurs after 46-50 round trips C: Caking occurs after 31-45 round trips D: Caking occurs after 16 to 30 round trips E: Caking occurs after 15 or fewer round trips.
[0084] Evaluation method 4: Drop test Each face powder was dropped once onto a plastic tile from a height of 40 cm, and the condition was observed. Five samples of each sample were subjected to the drop test. After the drop, the degree of disintegration was checked and evaluated according to the following evaluation criteria, and the average score of each of the five samples was judged according to the following evaluation criteria. <Evaluation criteria> (Score): (Evaluation result) 4: No change 3: Slight chips or gaps are observed 2: Chips and gaps are clearly visible 1: Dropping and cracking occur <Judgment criteria> (Judgment): (Average score) A: More than 3.5 points B: More than 3 points and less than 3.5 points C: More than 2 points but less than 3 points D: 2 points or less The results are shown in Tables 1 to 4.
