Abstract
Description
[Technical Field]
[0001] The present invention relates to a powder cosmetic, and more particularly to a powder cosmetic that is suitable as an anti-shine cosmetic. [Background technology]
[0002] Powder cosmetics such as face powder and powdery foundation are used to absorb excess oil contained in sebum and foundation and other cosmetics, reduce shine, and make the skin surface appear smooth. These cosmetics are required to be easy to spread on the skin, to cover skin imperfections such as blemishes, freckles, wrinkles, and pores, to make the skin look beautiful, and furthermore, to have a lasting effect.
[0003] Such powder cosmetics have been studied for some time. For example, Patent Document 1 describes that makeup cosmetics containing organopolysiloxane elastomer spherical powder, volatile silicone oil, and silicone resin have excellent pore-concealing effects (see Claim 1 and paragraph 0001), and also describes that powder cosmetics may be one embodiment of makeup cosmetics (see Examples 13, 14, and 19). However, powders made of elastomers generally have strong cohesive forces between particles, and powder cosmetics containing elastomers as powder components generally have the problem of being difficult to spread on the skin and making it difficult to achieve a uniform, smooth finish. Furthermore, organopolysiloxane elastomer powders have been found to be insufficient in terms of oil absorption capacity.
[0004] In recent years, there has been research into the use of elastomer spherical powders made from materials other than organopolysiloxane elastomers. For example, Patent Document 2 describes that a skin cosmetic containing (adipic acid / neopentyl glycol) crosspolymer powder and hydrophobically modified polyurethane is effective in correcting skin irregularities such as pores and fine wrinkles, has a refreshing feel when used, and is also effective in suppressing sebum production (see claim 1,
[0001] ).
[0005] In addition, Patent Document 3 discloses a volatile linear silicone oil and a Set a standard The oil absorption and special Set a standard The document describes a cosmetic containing an elastomer powder having a hardness in the range of 100 to 150°C, and states that the cosmetic spreads easily, is smooth and soft, and has a light, non-greasy feel when used (see claim 1 and paragraph 0011). The document also describes a specific example of the elastomer powder as an (adipic acid / neopentyl glycol) crosspolymer powder (see claim 3).
[0006] As described above, cosmetics that use an (adipic acid / neopentyl glycol) crosspolymer powder as an elastomer powder have been known for some time. However, the cosmetics of Patent Document 2 are preferably aqueous cosmetics (see paragraph 0019), and the cosmetics of Patent Document 3 are preferably water-in-oil emulsion cosmetics or oil-based cosmetics (see paragraph 0010). Neither document makes any mention of using an (adipic acid / neopentyl glycol) crosspolymer powder as a raw material for powder cosmetics. [Prior art documents] [Patent documents]
[0007] [Patent Document 1] Patent Publication No. 8-319215 [Patent Document 2] Republished WO2016-175216 [Patent Document 3] Japanese Patent Application Laid-Open No. 2017-066129 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]
[0008] The present invention was completed in light of this background technology, and its object is to provide a powder cosmetic that is easily spread on the skin, has the effect of correcting irregularities such as pores, has the effect of preventing shine, and has excellent makeup wear. [Means for solving the problem]
[0009] As a result of extensive research aimed at solving the above-mentioned problems, the present inventors have discovered that when a spherical powder of (adipic acid / neopentyl glycol) crosspolymer is used in combination with a fumed metal oxide, the ease of spreadability on the skin is improved compared to when either is used alone, and furthermore, a powder cosmetic can be obtained which has excellent effects of correcting skin irregularities, preventing shine, and long-lasting makeup, thereby completing the present invention.
[0010] Thus, according to the present invention, there is provided a powder cosmetic containing (A) 5 to 95 mass % of spherical powder of (adipic acid / neopentyl glycol) crosspolymer and (B) 0.1 to 30 mass % of fumed metal oxide. [Effects of the Invention]
[0011] The powder cosmetic of the present invention uses an (adipic acid / neopentyl glycol) crosspolymer spherical powder, which is an elastic powder with high oil absorption capacity, to prevent shine caused by excess oil and sebum and to make irregularities such as pores less noticeable. Furthermore, while elastomeric powders generally tend to aggregate, the powder cosmetic of the present invention inhibits aggregation of the (adipic acid / neopentyl glycol) crosspolymer spherical powder by incorporating a fumed metal oxide, resulting in a powder cosmetic that is easy to spread and gives a smooth finish. DETAILED DESCRIPTION OF THE INVENTION
[0012] The powder cosmetic of the present invention contains, as essential components, (A) (adipic acid / neopentyl glycol) crosspolymer spherical powder and (B) fumed metal oxide. Each component will be explained below. (A) (Adipic acid / neopentyl glycol) crosspolymer spherical powder The (A) (adipic acid / neopentyl glycol) crosspolymer spherical powder used in the present invention is a spherical powder made of a copolymer of adipic acid and neopentyl glycol crosslinked with isopropyltriethoxysilane. The spherical shape of the powder scatters and reflects light when applied to the skin, making skin irregularities such as pores less visible. Furthermore, the spherical shape makes it easy to spread on the skin due to the rolling effect. In the present invention, "spherical" may refer to either a perfect sphere or an approximately sphere, with the ratio of major axis to minor axis preferably being 1.5 or less, more preferably 1.2 or less.
[0013] The volume average particle size of the (adipic acid / neopentyl glycol) crosspolymer spherical powder used in the present invention is preferably 1 to 30 μm, and more preferably 2 to 20 μm. If the volume average particle size is too small, the powder tends to be difficult to spread, while if it is too large, adhesion to the skin tends to decrease. In the present invention, the volume average particle size can be measured using a laser diffraction / scattering particle size distribution analyzer (LA-950, manufactured by Horiba, Ltd.) after ultrasonically dispersing the powder in 95% by volume ethanol for 5 minutes using an ultrasonic cleaner (W-113, 28 kHz) manufactured by Honda Electronics Co., Ltd.
[0014] The oil absorption capacity of the (adipic acid / neopentyl glycol) crosspolymer spherical powder used in the present invention is 100% of that of dimethicone (kinematic viscosity at 25°C 6mm). 2 / s) oil absorption (hereinafter simply referred to as "dimethicone oil absorption"). Dimethicone oil absorption can be measured in accordance with JIS K-5101, except that dimethicone (trade name: Silicone KF-96A-6cs, manufactured by Shin-Etsu Chemical Co., Ltd.) is used instead of the linseed oil specified in JIS K-5101. Specifically, 1 g of powder is placed on a glass plate, and small amounts of dimethicone are dropped into the center of the powder. After each drop, the mixture is kneaded with a spatula until uniform, and the end point is defined as the time just before the entire mixture becomes a paste and becomes fluid, and the dimethicone oil absorption is calculated using the following formula. Dimethicone oil absorption (g / 100g) = (amount of dimethicone used (g) / amount of sample (g)) x 100
[0015] The dimethicone oil absorption of the (adipic acid / neopentyl glycol) crosspolymer spherical powder used in the present invention is preferably 40 to 500 g / 100 g, more preferably 100 to 400 g / 100 g, and particularly preferably 130 to 400 g / 100 g. By having it in this range, particularly good shine-preventing effect and makeup-lasting effect can be obtained.
[0016] The content of the (adipic acid / neopentyl glycol) crosspolymer spherical powder used in the present invention is 5 to 95% by mass, preferably 10 to 90% by mass, and particularly preferably 20 to 70% by mass, based on the total mass of the cosmetic. This range provides good shine prevention and makeup long-lasting effects.
[0017] Commercially available products may be used as the (adipic acid / neopentyl glycol) crosspolymer spherical powder, and examples of such commercially available products include Penstia Powder manufactured by CENTERCHEM and SILESTER 313 VS POWDER manufactured by KODA Co., Ltd. Among these, SILESTER 313 VS POWDER is preferably used because of its high oil absorption capacity.
[0018] (B) Fume-like metal oxide In the present invention, the fumed metal oxide of component (B) is used to suppress aggregation of the spherical powder of component (A). While aggregation of powder particles cannot be avoided with component (A) alone, when component (B) is mixed, it adheres to the surface of the spherical powder of component (A), effectively suppressing aggregation of component (A). As a result, the cosmetic composition is easier to spread on the skin and can be applied evenly to the skin.
[0019] Fumed metal oxides are fine amorphous metal oxides obtained by flame hydrolysis, and have the appearance of fluffy, light powder. Industrially, silica, alumina, titanium oxide, etc. are available. For example, fumed silica can be obtained by high-temperature hydrolysis of a raw material such as silicon tetrachloride in an oxyhydrogen flame. The specific surface area of the fumed metal oxide is preferably 20 m 2 / g or more, and more preferably 30 to 400m 2 / g, and particularly preferably 40 to 400m 2 If the specific surface area is too small, it will be difficult for the particles to adhere to the surface of the spherical powder of component (A).
[0020] The primary particle diameter of these fumed metal oxides is preferably 50 nm or less, and particularly preferably 30 nm or less. The primary particle diameter can be determined as the average value of 100 particles measured using an electron microscope photograph. In this specification, when the fumed metal oxide is a commercially available product, the nominal value from the manufacturer is used. Component (B) may be an untreated fumed metal oxide that exhibits hydrophilicity, or a fumed metal oxide that has been subjected to a hydrophobic treatment. Specific examples of hydrophobic treatments include dimethyldichlorosilane treatment, trimethylsiloxy treatment using trimethylsilyl chloride or hexamethyldisilazane, octylsilane treatment, dimethylsilicone oil treatment, coating and baking treatment using methylhydrogenpolysiloxane, and metal soap coating.
[0021] The fumed metal oxide of component (B) is preferably one or more selected from silica, alumina, and titanium oxide. Of these, alumina is particularly preferred because it has a higher refractive index than silica, which provides a high unevenness correction effect, and a lower refractive index than titanium oxide, which allows for a natural finish without a whitish cast.
[0022] The fumed metal oxide of component (B) can be a commercially available product. Commercially available examples of fumed silica include AEROSIL 50, AEROSIL 130, AEROSIL 200, AEROSIL 200V, AEROSIL 200CF, AEROSIL 200FAD, AEROSIL 300, AEROSIL 300CF, AEROSIL 380, AEROSIL 380S, AEROSIL R972, AEROSIL R972V, AEROSIL R972CF, AEROSIL R974, AEROSIL R976S, AEROSIL RX200, AEROSIL RX300, AEROSIL RY200, AEROSIL R202, AEROSIL R805, AEROSIL R812, and AEROSIL RA200H (all manufactured by Nippon Aerosil Co., Ltd.), and CAB-O-SIL Examples of commercially available fumed alumina include AEROXIDE Alu C (manufactured by Nippon Aerosil Co., Ltd.), and examples of commercially available fumed titanium oxide include AEROXIDE TiO2 P25 (manufactured by Nippon Aerosil Co., Ltd.).
[0023] The content of the fumed metal oxide (B) used in the present invention is 0.5 to 30% by mass, preferably 0.5 to 20% by mass, and particularly preferably 1 to 10% by mass, based on the total cosmetic composition. By using this range, it is possible to effectively suppress the aggregation of component (A), resulting in a powder cosmetic composition that is easy to spread and has excellent anti-shine effect and makeup retention. If the content of component (B) is too high, the spreadability and anti-shine effect will be insufficient. Conversely, if the content is too low, it will not be possible to suppress the aggregation of component (A), resulting in a decrease in the ease of spreadability and anti-shine effect.
[0024] In the present invention, in addition to the above-mentioned components (A) and (B), other components commonly used in the preparation of powder cosmetics can be appropriately blended within a range that does not essentially impair the effects of the present invention, such as spherical powders other than component (A), non-spherical powders, extender pigments, coloring pigments, oily components, UV scattering agents, UV absorbers, etc. In particular, blending a plate-like powder (C) together with components (A) and (B) is a preferred embodiment, as it can improve adhesion to the skin.
[0025] (C) Plate-shaped powder The plate-like powder preferably has a particle size of 1 to 100 μm, more preferably 3 to 40 μm. The plate-like powder preferably has an aspect ratio (particle length / thickness) of 8 to 120. Examples of plate-like powders include mica, synthetic mica, sericite, talc, kaolin, plate-like barium sulfate, plate-like hydroxyapatite, plate-like alumina, boron nitride, lauroyl lysine, titanium dioxide-coated mica, bismuth oxychloride, titanium dioxide-coated talc, fish scale foil, silica flakes, glass flakes, and metallic aluminum flakes. Among these, mica, synthetic mica, sericite, and talc are preferred from the viewpoints of ease of spreading and adhesion to the skin. When a plate-like powder is used, its content is preferably 5 to 94.9% by mass, more preferably 10 to 80% by mass, and particularly preferably 20 to 70% by mass, based on the total weight of the cosmetic. By blending the plate-like powder in this range, it becomes easy to obtain a cosmetic that spreads well on the skin and adheres easily to the skin.
[0026] The powder cosmetic of the present invention may contain other powder components in addition to components (A), (B), and (C). Examples of other powder components include color pigments such as titanium oxide, iron oxide, and organic pigments; spherical powders other than component (A), such as spherical polyurethane, spherical nylon, spherical PMMA, spherical silicone elastomer, and spherical silica; and ultraviolet scattering powders such as fine particle titanium oxide and fine particle zinc oxide.
[0027] Examples of oily ingredients that can be blended include naturally occurring oils and waxes such as macadamia nut oil, avocado oil, corn oil, olive oil, rapeseed oil, sesame oil, castor oil, safflower oil, cottonseed oil, jojoba oil, coconut oil, palm oil, liquid lanolin, hydrogenated coconut oil, hydrogenated oil, Japan wax, hydrogenated castor oil, beeswax, candelilla wax, carnauba wax, Ibota wax, lanolin, reduced lanolin, hard lanolin, and jojoba wax; liquid paraffin, squalane, pristane, and ozokera. Hydrocarbons such as cellulose, paraffin, ceresin, petrolatum, and microcrystalline wax; higher fatty acids such as oleic acid, isostearic acid, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, and undecylenic acid; higher alcohols such as cetyl alcohol, stearyl alcohol, isostearyl alcohol, behenyl alcohol, octyldodecanol, myristyl alcohol, and cetostearyl alcohol; cetyl isooctanoate, isopropyl myristate Pyr, hexyldecyl isostearate, diisopropyl adipate, di-2-ethylhexyl sebacate, cetyl lactate, diisostearyl malate, ethylene glycol di-2-ethylhexanoate, neopentyl glycol dicaprate, glycerin di-2-heptylundecanoate, triethylhexanoin, trimethylolpropane tri-2-ethylhexanoate, trimethylolpropane triisostearate, pentane erythritol tetra-2-ethylhexanoate, etc. synthetic ester oils; chain polysiloxanes such as dimethylpolysiloxane, methylphenylpolysiloxane, and diphenylpolysiloxane; cyclic polysiloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane; and silicone oils such as modified polysiloxanes such as amino-modified polysiloxanes, polyether-modified polysiloxanes, alkyl-modified polysiloxanes, and fluorine-modified polysiloxanes.
[0028] When an oily component is blended, its content is preferably 0.1 to 30% by mass relative to the total powder cosmetic. By blending an oily component, the powder cosmetic feels good to the skin. When the powder cosmetic is a smooth powder, i.e., a loose powder, the blending amount of the oily component is preferably 0.1 to 20% by mass, particularly 1 to 10% by mass. Furthermore, when the powder cosmetic is in a solid form, the blending amount of the oily component is preferably 3 to 30% by mass, particularly 5 to 15% by mass relative to the total powder cosmetic. In either case, if the content of the oily component is excessively high, the ease of spreading tends to decrease.
[0029] Specific examples of other ingredients that can be added include polyhydric alcohols such as polyethylene glycol, glycerin, 1,3-butylene glycol, erythritol, sorbitol, xylitol, maltitol, propylene glycol, dipropylene glycol, diglycerin, isoprene glycol, 1,2-pentanediol, 2,4-hexylene glycol, 1,2-hexanediol, and 1,2-octanediol; hyaluronic acid, sodium hyaluronate, sodium pyrrolidone carboxylate, lactic acid, and sodium lactate. Examples of such ingredients include moisturizing ingredients such as PEG-100, PEG-120, PEG-140, PEG-180, PEG-190, PEG-200, PEG-210, PEG-220, PEG-230, PEG-240, PEG-250, PEG-260, PEG-270, PEG-280, PEG-290, PEG-300, PEG-310, PEG-320, PEG-330, PEG-340, PEG-350, PEG-360, PEG-370, PEG-380, PEG-390, PEG-400, PEG-410, PEG-420, PEG-430, PEG-440, PEG-450, PEG-460, PEG-470, PEG-480, PEG-49 ...
[0030] In addition, the UV absorption ability (SPF value and PA value) of cosmetics can be improved by incorporating organic UV absorbers such as para-aminobenzoic acid-based UV absorbers, anthranilic acid-based UV absorbers, salicylic acid-based UV absorbers, cinnamic acid-based UV absorbers, benzophenone-based UV absorbers, sugar-based UV absorbers, 2-(2'-hydroxy-5'-t-octylphenyl)benzotriazole, and 4-methoxy-4'-t-butyldibenzoylmethane.
[0031] The powder cosmetic of the present invention may be in either a powder or solid form, and specific examples of its usage include face powder, control color, face color, blush, highlighter, foundation, etc. Among these, a usage form in which it is applied directly to bare skin as an anti-shine powder or applied over an emulsified foundation is suitable.
[0032] The powder cosmetic of the present invention can be prepared by uniformly mixing the aforementioned components (A) and (B), and any other components used as needed, according to a conventional method. All components may be mixed simultaneously, or components (A) and (B) may be mixed in advance and then the other components may be mixed. Among these mixing methods, the method of premixing only components (A) and (B) can more effectively suppress aggregation of the spherical powder of component (A).
[0033] The mixed powder thus obtained can be filled directly into a container to produce a loose powder. Alternatively, the mixed powder can be filled into a container and then pressed to produce a solid powder (pressed powder). Since a mixed powder consisting of only components (A) and (B) is difficult to mold, a manufacturing method that involves adding a volatile solvent (e.g., one or more selected from water, lower alcohols, volatile silicones, light liquid isoparaffin, etc.) to the mixed powder and then molding it is advantageous. Since a high content of component (A) tends to reduce shape retention, when a large amount of component (A) is included, a loose powder formulation is preferable to a solid powder from the standpoint of shape retention. [Example]
[0034] The present invention will be described in more detail below with reference to examples and comparative examples, but the present invention is not limited to these examples. In the following description, the blending amounts in the formulations are expressed in mass % of the total amount unless otherwise specified.
[0035] Examples 1 to 5 and Comparative Examples 1 to 3 (loose powder) A powder cosmetic (loose powder) with the formulation shown in Table 1 was prepared according to the preparation method below using KODA's SILESTER 313 VS POWDER (volume average particle size 5 μm, dimethicone oil absorption 210 g / 100 g) as the (adipic acid / neopentyl glycol) crosspolymer, component (A), and Nippon Aerosil's AEROXIDE Alu C (average particle size approximately 13 nm) as the fumed alumina, component (B), and the performance of the resulting powder cosmetic was evaluated. The methods for measuring the coefficient of dynamic friction and for evaluating ease of spreadability, non-glossiness, and pore visibility are as follows.
[0036] (Preparation method) Using a sample mill SK-M10 manufactured by Kyoritsu Riko Co., Ltd., component (A) and component (B) were mixed for 20 seconds at a power of 80 (approximately 15,000 rpm) to obtain the powder cosmetics of Examples 1 to 5 and Comparative Example 2. In Comparative Examples 1 and 3, commercially available products were used as they were.
[0037] (Method for measuring the coefficient of dynamic friction) Equipment used: Trinity Lab static and dynamic friction measuring instrument TL201Tt Measurement method: 0.5 mg / cm of sample was applied to a model skin (Bioskin Plate manufactured by Viewlux). 2 The coefficient of dynamic friction was measured using a urethane tactile contactor under the conditions of a load of 25 g, a movement speed of 1 mm / sec, and a measurement distance range of 20 mm. (Evaluation method for powder cosmetics) For the following evaluation items a to d, 10 evaluators applied each sample to their own faces and gave a score on a 5-point scale from 0 to 4 based on the evaluation criteria shown in (1) below. The scores of the 10 evaluators were totaled and the performance as an anti-shine powder was judged according to the 4-point evaluation criteria shown in (2) below. (Evaluation items) a. Ease of stretching b. No shine (immediately after application) c. Pores are less visible d. No shine (4 hours after application)
[0038] (1) Evaluation criteria (Rating): (Evaluation) 4: Good 3: Fairly good 2:Normal 1: Somewhat bad 0: Bad
[0039] (2) 4-level evaluation criteria (Judgment): (Total score) A: Total score is 31 to 40 points B: Total score is 21 to 30 points C: Total score is 11 to 20 points D: Total score is 0 to 10 points
[0040] [Table 1]
[0041] As can be seen from the results in Table 1, the powder cosmetics of Examples 1 to 5 had a smaller coefficient of dynamic friction and were easier to spread than those containing component (A) alone (Comparative Example 1). They also had excellent anti-shine and pore-concealing effects (irregularity correction effects). In contrast, when component (B) was not included (Comparative Example 1), not only was spread insufficient, but the pore-concealing effect was also poor. Furthermore, when the content of component (B) was 50% by mass (Comparative Example 2), the spread and pore-concealing effects were insufficient, and the anti-shine effect was also somewhat lacking. When component (B) was used alone (Comparative Example 3), the spread, anti-shine effect, and pore-concealing effect were all poor.
[0042] Examples 6 to 10 and Comparative Examples 4 to 5 <Shine prevention powder> The loose anti-shine powders having the formulations shown in Table 2 were prepared by the manufacturing method shown below and evaluated by the methods described above. The formulations and results are also shown in Table 2.
[0043] (Manufacturing method) A: Mix ingredients 1 to 11. B: Add ingredients 12 and 13 to the mixture obtained in A above and mix. C: The mixture obtained in B above was filled into a powder container to obtain a loose anti-shine powder.
[0044] [Table 2]
[0045] Of the components listed in Table 2, *1 and *2 are as described above, and *3 to *7 are as follows: *3 Product name: Toray Industries SP-500 (volume average particle size: 5 μm) *4 Product name: AEROSIL RY200 (average particle size approximately 12 nm, dimethicone treatment) manufactured by Nippon Aerosil Co., Ltd. *5 Product name: AEROXIDE TiO2 P-25 (average particle size: approx. 21 nm) manufactured by Nippon Aerosil Co., Ltd. *6 Product name: Silica Microbead P-1500 (volume average particle diameter 5 μm) manufactured by JGC Catalysts and Chemicals Co., Ltd. *7 Product name: Asada Flour Milling Co., Ltd. JA-46R Talc
[0046] As is clear from the results in Table 2, the anti-shine powders of Examples 6 to 10 were excellent in terms of ease of spreading, anti-shine effect, unevenness correction effect (making pores less noticeable), and anti-shine effect over time (makeup longevity effect). ( Adipic Acid / Neopentyl Glycol )The powder of Comparative Example 4, which used nylon powder instead of cross-polymer, was inferior in anti-gloss effect, and the powder of Comparative Example 5, which did not contain fumed metal oxide, was inferior in terms of ease of spreading and unevenness correction effect.
[0047] Example 11 <Shine-preventing pressed powder> Anti-shine pressed powders having the formulations shown in Table 3 were prepared by the manufacturing method shown below and evaluated in the same manner as above. The results are also shown in Table 3.
[0048] (Manufacturing method) A: Mix ingredients 1 to 10. B: Components 11 to 13 are added to the mixture obtained in A above and mixed. C: The mixture obtained in B above was filled into a metal dish and press-molded to obtain an anti-gloss powder.
[0049] [Table 3]
[0050] As is clear from the results in Table 3, the oil-preventing pressed powder of Example 11 was excellent in all respects: ease of spreading, oil-preventing, unevenness correction, and makeup longevity. [Industrial Applicability]
[0051] The powder cosmetic of the present invention is particularly suitable for use as an anti-shine cosmetic, since it is easily spreadable on the skin, has excellent anti-shine effect and its long-lasting effect, and is effective in correcting skin irregularities.
