Description

[Technical field]

[0001] The present invention relates to a cosmetic composition for UV protection. [Background technology]

[0002] In recent years, there has been an increasing demand for high functionality (high SPF and PA values, etc.) of UV protection cosmetics, and there is also a growing demand for improved usability. Generally, UV protection cosmetics exert their UV protection effect by blending UV absorbers and UV scattering agents (titanium oxide, zinc oxide, etc.).

[0003] As a means to enhance the ultraviolet protection effect, cosmetics containing a high content of ultraviolet absorbing agent (Patent Document 1) and sunscreen cosmetics containing a high content of ultraviolet scattering agent (Patent Document 2) have been developed. However, as the amount of ultraviolet absorbing agent and ultraviolet scattering agent is increased as in these cases, although the ultraviolet protection effect is enhanced, the feeling of use, such as stickiness and squeaking, tends to be impaired.

[0007] According to the present invention, it is possible to provide a composition for an ultraviolet protective cosmetic preparation that has an ultraviolet protective effect (for example, a good SPF value) and is also pleasant to use. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The UV protective cosmetic composition of the present invention comprises the following components (A) to (F): (A) an ultraviolet absorber, (B) an ultraviolet scattering agent, (C) Spherical powder, (D) a silicone-based film-forming agent, (E) a silicone surfactant, and (F) a volatile solvent; and the ratio of the contents of components (A) and (B) ((A) / (B)) is 0.6 to 5 by mass (hereinafter, the UV protective cosmetic composition of the present invention is also referred to as the composition of the present invention or the present composition). In this specification, (A) to (F) are symbolic symbols of components, and hereinafter may be referred to as component (A), etc.

[0009] Component (A) Component (A) is an ultraviolet absorbing agent. In this specification, an ultraviolet absorbing agent means a chemical substance that absorbs ultraviolet rays and converts them into energy such as heat through a chemical reaction, thereby preventing the ultraviolet rays from reaching a target (e.g., skin). By including an ultraviolet absorbing agent, the composition can improve ultraviolet protection.

[0010] The ultraviolet absorbing agent can be one that is usually mixed in ultraviolet protection cosmetics. Examples of ultraviolet absorbing agents include cinnamic acid derivatives, paraaminobenzoic acid (PABA) derivatives, benzophenone derivatives, salicylic acid derivatives, polysilicone, and other ultraviolet absorbing organic compounds, and more specifically, examples thereof include ethylhexyl methoxycinnamate, diethylaminohydroxybenzoyl hexyl benzoate, bisethylhexyloxyphenol methoxyphenyl triazine, methylenebisbenzotriazolyltetramethylbutylphenol, polysilicone-15, octocrylene, dimethicone diethyl benzal malonate, t-butyl methoxydibenzoylmethane, ethylhexyl triazone, oxybenzone-3, phenylbenzimidazole sulfonic acid, homosalate, and ethylhexyl salicylate.

[0011] The ultraviolet absorber of component (A) is preferably at least one selected from the group consisting of ethylhexyl methoxycinnamate, diethylamino hydroxybenzoyl hexyl benzoate, bisethylhexyloxyphenol methoxyphenyl triazine, methylene bisbenzotriazolyl tetramethylbutylphenol, and polysilicone-15. This allows for better ultraviolet absorption and a formulation with good usability. The ultraviolet absorber is more preferably ethylhexyl methoxycinnamate.

[0012] The composition can improve SPF and PA by containing an ultraviolet absorbing agent. The ultraviolet absorbing agent can usually exhibit ultraviolet absorbing effects according to the wavelength region of ultraviolet absorption. For example, if there is an absorption wavelength in the UVB region (wavelength 280 to 320 nm), it can absorb UVB, and if there is an absorption wavelength in the UVA region (320 to 400 nm), it can absorb UVA. Therefore, by using an ultraviolet absorbing agent having UVB absorption, SPF can be improved. Also, by using an ultraviolet absorbing agent having UVA absorption, PA can be improved. Among the above components, for example, ethylhexyl methoxycinnamate and polysilicone-15 have excellent UVB absorption. Also, for example, diethylamino hydroxybenzoyl hexyl benzoate has excellent UVA absorption. Also, bisethylhexyloxyphenol methoxyphenyl triazine and methylene bisbenzotriazolyl tetramethylbutylphenol have excellent absorption of both UVB and UVA.

[0013] "SPF" is an abbreviation for Sun Protection Factor, and is an index showing the effectiveness of a product in preventing sunburn (redness caused by the sun) caused mainly by UVB. "PA" is an abbreviation for Protection Grade of UVA, and is an index showing the effectiveness of a product in preventing UVA.

[0014] The component (A) blended in the present composition may be one type or two or more types.

[0015] The content of component (A) (the total amount when there are multiple components) is not limited thereto, but from the viewpoint of obtaining a preparation that enhances UV protection properties and has a good feel when used, it is preferably 0.01 to 50 mass%, more preferably 0.1 to 30 mass%, and even more preferably 1 to 20 mass% relative to the total amount of the composition (100 mass%).

[0016] Ingredient (B) Component (B) is an ultraviolet scattering agent. In this specification, the ultraviolet scattering agent means a substance that has the function of scattering or reflecting ultraviolet rays to prevent them from reaching a target (e.g., skin). By containing an ultraviolet scattering agent, the composition can improve ultraviolet protection. In particular, by using an ultraviolet absorber and an ultraviolet scattering agent in combination, ultraviolet protection (especially SPF value, etc.) can be significantly improved.

[0017] Examples of ultraviolet scattering agents include, but are not limited to, metal oxide powders, specifically titanium oxide, zinc oxide, etc. Component (B) is preferably at least one selected from titanium oxide and zinc oxide.

[0018] The ultraviolet scattering agent is preferably a powder, but the powder may be a powder whose surface has been treated with a surface treatment agent (surface-treated powder). The surface treatment can suppress the aggregation of the powder, increase the adhesion of the powder to the skin, increase the affinity with other raw materials, and increase the functionality of the powder (e.g., usability). Examples of the surface treatment include fluorine compound treatment, silica treatment, alumina treatment, aluminum hydroxide treatment, silicone treatment (methicone treatment, hydrogen dimethicone treatment, dimethicone treatment, etc.), silicone resin treatment, pendant treatment, silane coupling agent treatment, titanium coupling agent treatment, silane treatment, oil treatment, surfactant treatment, lecithin treatment, N-acylated lysine treatment, polyacrylic acid treatment, metal soap treatment, acrylic resin treatment, and metal oxide treatment. These surface treatments may be used alone or in combination of two or more.

[0019] The amount of the surface treatment agent to be used is preferably 0.1 to 30% by mass, more preferably 0.5 to 20% by mass, and further preferably 1 to 10% by mass, based on the untreated powder.

[0020] The surface treatment can be carried out by a conventional method. For example, a surface treatment agent and powder particles to be treated are added to a solvent, and the powder particles are stirred in a ball mill or the like, and then dried as necessary, washed with water, and filtered repeatedly to remove impurities, and then dried and pulverized to obtain the desired surface-treated powder. In addition, several types of compounds that are surface treatment agents can be simultaneously used for surface treatment, or the surface can be previously treated with one compound, and then surface-treated with another compound.

[0021] In one embodiment, the present composition preferably contains titanium oxide (including surface-treated titanium oxide) as an ultraviolet scattering agent. Titanium oxide may be used without particular limitations on its shape, such as spherical, plate-like, needle-like, or irregular shape, or on its particle structure, such as porous or nonporous, as long as it is titanium oxide that is normally used in cosmetics. Titanium oxide may be of the rutile type or anatase type. Titanium oxide having an average particle diameter of, for example, 10 to 1,000 nm may be used.

[0022] In another embodiment, the present composition preferably contains zinc oxide (including surface-treated zinc oxide) as an ultraviolet scattering agent. The zinc oxide may be any zinc oxide commonly used in cosmetics, without particular limitations on its shape (e.g., spherical, plate-like, needle-like, irregular, etc.) or its particle structure (e.g., porous, non-porous, etc.). For example, zinc oxide having an average particle diameter of 10 to 5,000 nm may be used.

[0023] The component (B) to be blended in the present composition may be one type or two or more types. For example, only titanium oxide or zinc oxide may be blended, or both titanium oxide and zinc oxide may be blended. In this case, surface-treated titanium oxide may be blended as the titanium oxide, or surface-treated zinc oxide may be blended as the zinc oxide. In the present composition, the UV absorption wavelength range can be controlled by appropriately selecting the types of ultraviolet absorbing agent and ultraviolet scattering agent, and a cosmetic product with excellent ultraviolet protection effect (high SPF and PA) can be obtained.

[0024] The content of component (B) (the total amount when there are multiple components) is not limited thereto, but from the viewpoint of obtaining a preparation that enhances UV protection properties and has a good feel when used, it is preferably 0.01 to 50 mass%, more preferably 0.1 to 30 mass%, and even more preferably 1 to 20 mass% relative to the total amount of the composition (100 mass%).

[0025] Here, the ratio of component (A) to component (B) ((A) / (B)) is 0.6 to 5 by mass. When the ratio of the content of component (A) to the content of component (B) is within this range, a preparation with a good feel in use with reduced stickiness and squeaking can be obtained. Furthermore, when this ratio is within the above range, a well-balanced ultraviolet absorbing action and ultraviolet scattering action can be obtained, and a preparation with excellent ultraviolet protection effect can be obtained. From the viewpoint of improving the feel in use, this ratio ((A) / (B)) is preferably 0.6 to 4, more preferably 0.7 to 3, and even more preferably 0.8 to 2.

[0026] Ingredients (C) Component (C) is a spherical powder. In this specification, spherical powder means a powder consisting of spherical particles. Powder particles of cosmetic raw materials come in various shapes such as spherical, plate-like, needle-like, and irregular shapes, and among these, those classified as spherical particles are component (C). The shape of the particles of the spherical powder does not have to be a perfect sphere, and particles with a shape close to a sphere are also included in the spherical powder. Specifically, spherical includes not only a perfect sphere but also an approximately spherical shape, an oval sphere, a pseudo-spherical shape, and the like. The shape of the particles can be confirmed, for example, by a scanning electron microscope (SEM).

[0027] Examples of the spherical powder include silicic acid compounds, acrylic acid or methacrylic acid compounds, and the like, with silicic acid compounds being particularly preferred, and siloxane compounds being particularly preferred. Examples of the spherical powder include silica, (vinyl dimethicone / methicone silsesquioxane) crosspolymer, (diphenyl dimethicone / vinyl diphenyl dimethicone / silsesquioxane) crosspolymer, polymethyl silsesquioxane, and methyl methacrylate crosspolymer. Of these, the spherical powder is preferably at least one selected from the group consisting of silica, (vinyl dimethicone / methicone silsesquioxane) crosspolymer, (diphenyl dimethicone / vinyl diphenyl dimethicone / silsesquioxane) crosspolymer, and polymethyl silsesquioxane.

[0028] Here, in this specification, when the powder constituting the ultraviolet scattering agent of component (B) is spherical, this powder also serves as component (C). That is, the spherical powder that is an ultraviolet scattering agent is component (B) and component (C). In this specification, a component that is component (B) and component (C) is referred to as component (BC). Specifically, for example, spherical titanium oxide and spherical zinc oxide that function as ultraviolet scattering agents are component (BC). In addition, in the calculation of the content ratio of each component described later, when the ultraviolet scattering agent of component (B) is composed of spherical powder, the powder is added to component (B) and also to component (C) for calculation. That is, the content of component (BC) is the content of component (B) and the content of component (C).

[0029] The spherical powder of component (C) is preferably composed of particles with an average particle size of 1 to 20 μm. This can further improve the ultraviolet protection properties. The average particle size is more preferably 1 to 15 μm, and even more preferably 1 to 10 μm. Without being bound by theory, it is believed that the smaller the particle size of the spherical powder, the more particles are dispersed in the formulation, and the more the effects of the ultraviolet absorbing agent and the ultraviolet scattering agent can be improved. In this specification, the average particle size of the powder is the volume average particle size measured using a laser diffraction particle size distribution meter (this also applies to other components).

[0030] The component (C) blended in the present composition may be one type or two or more types.

[0031] The content of component (C) (the total amount when there are multiple components) is not limited thereto, but from the viewpoint of obtaining a preparation that enhances UV protection properties and has a good feel when used, it is preferably 0.001 to 30 mass%, more preferably 0.01 to 20 mass%, and even more preferably 0.1 to 10 mass%, relative to the total amount of the composition (100 mass%).

[0032] Ingredients (D) Component (D) is a silicone-based film-forming agent. In this specification, the film-forming agent means a substance that exerts the action of forming a film when applied as a cosmetic to a target (skin, hair, etc.). The silicone-based film-forming agent is a film-forming agent based on silicone. The silicone-based film-forming agent forms a film by organopolysiloxane having a three-dimensional network structure. In this specification, film formation means that a solution in which the component to be the film-forming agent is dissolved at 40% in a solvent in which the component is soluble is applied to a glass plate with a 400 μm thick applicator, and a film is formed after drying at room temperature for 24 hours. Here, examples of the solvent in which the component is soluble include volatile silicone oils and volatile hydrocarbon oils, and specifically, decamethylcyclopentasiloxane, short-chain dimethicone, isododecane, etc.

[0033] The silicone-based film-forming agent is not particularly limited as long as it is one that is normally used in cosmetics, and examples thereof include alkylsiloxysilicate, fluoroalkylsiloxysilicate, acrylic-silicone graft copolymer, long-chain alkyl-modified acrylic-silicone graft copolymer, polyvinylpyrrolidone-modified methylpolysiloxane, and the like. Specific examples thereof include trimethylsiloxysilicate, (acrylates / dimethicone) copolymer, trifluoroalkyldimethyltrimethylsiloxysilicate, and the like.

[0034] Component (D) is preferably at least one selected from the group consisting of trimethylsiloxysilicate and acrylates / dimethicone copolymer, which can provide a preparation with improved UV protection and better usability.

[0035] The component (D) blended in the present composition may be one type or two or more types.

[0036] The content of component (D) (the total amount when there are multiple components) is not limited thereto, but from the viewpoint of obtaining a preparation that enhances UV protection properties and has a good feel when used, it is preferably 0.001 to 50 mass%, more preferably 0.01 to 30 mass%, and even more preferably 0.05 to 10 mass%, relative to the total amount of the composition (100 mass%).

[0037] Here, the ratio of the contents of components (C) and (D) ((C) / (D)) is preferably 0.01 to 50 by mass. When the ratio of the content of component (C) to the content of component (D) is within this range, a more uniform coating film can be obtained, and the ultraviolet protection properties can be improved. From the same viewpoint, this ratio ((C) / (D)) is more preferably 0.02 to 40, and even more preferably 0.05 to 30.

[0038] In addition, in the present composition, the ratio (((A)+(B)) / ((C)+(D))) of the total content of components (A) and (B) to the total content of components (C) and (D) is preferably 1 to 100 by mass ratio. This makes it possible to obtain a preparation that has enhanced UV protection properties and a good feel when used. From the same viewpoint, this ratio (((A)+(B)) / ((C)+(D))) is more preferably 1 to 50, even more preferably 2 to 30, and even more preferably 3 to 10.

[0039] Ingredient (E) Component (E) is a silicone surfactant. In the present composition, the use of a silicone surfactant can improve the UV protection and also improve the feeling of use. The silicone surfactant preferably has a PEG or polyglyceryl moiety as a hydrophilic moiety, and a silicone and / or alkyl moiety as a hydrophobic moiety. The silicone surfactant is compatible with the silicone film-forming agent of component (D), and is considered to enhance the action of the silicone film-forming agent and improve the UV protection. In addition, the use of a silicone surfactant is considered to provide a smooth feeling of use.

[0040] It is more preferable that component (E) is an alkyl-modified silicone surfactant, in which case the ultraviolet protection properties can be further improved.

[0041] Examples of alkyl-modified silicone surfactants include, but are not limited to, lauryl PEG-9 polydimethylsiloxyethyl dimethicone, cetyl dimethicone copolyol, lauryl polyglyceryl-3 polydimethylsiloxyethyl dimethicone, cetyl PEG / PPG-10 / 1 dimethicone, (PEG-15 / lauryl dimethicone) crosspolymer, (acrylates / ethylhexyl acrylate / dimethicone methacrylate) copolymer, and the like.

[0042] Examples of silicone surfactants other than those mentioned above include PEG-9 polydimethylsiloxyethyl dimethicone, PEG-10 dimethicone, PEG-9 dimethicone, PEG-3 dimethicone, PEG-9 methyl ether dimethicone, PEG-11 methyl ether dimethicone, PEG-32 methyl ether dimethicone, PEG / PPG-20 / 22 butyl ether dimethicone, (dimethicone / (PEG-10 / 15)) crosspolymer, etc. Component (E) may be used alone or in combination of two or more.

[0043] The content of component (E) in the present composition (the total amount when multiple components are present) is not limited to this, but from the viewpoint of enhancing UV protection properties, it is, for example, preferably 0.001 to 30 mass%, more preferably 0.01 to 20 mass%, and even more preferably 0.1 to 10 mass%, relative to the total amount of the present composition (100 mass%).

[0044] Component (F) Component (F) is a volatile solvent. In this specification, the volatile solvent may be an organic solvent that volatilizes when left at room temperature under open conditions (for example, when placed in a beaker in a predetermined amount). For example, the volatile solvent may be an organic solvent having a boiling point of 260°C or less at normal pressure. Water is not included in the volatile solvent. By blending a volatile solvent, it becomes easier to form a uniform coating film, and the ultraviolet protection property can be improved. In addition, by blending a volatile solvent, stickiness can be suppressed, and the feeling of use can be improved.

[0045] Examples of the volatile solvent include volatile alcohol-based solvents, ether-based solvents, ketone-based solvents, ester-based solvents, hydrocarbon-based solvents, and silicone-based solvents.

[0046] Component (F) is preferably a silicone-based volatile oil (silicone-based solvent). The silicone-based volatile oil has a viscosity of 10 mm at 25° C. 2Dimethylpolysiloxanes with a viscosity of 20 mm / s or less, alkyl trimethicones such as methyl trimethicone, and 2 Examples of suitable methylphenylpolysiloxanes include methylphenylpolysiloxane, cyclomethicone, and decamethylcyclopentasiloxane with a viscosity of 100 / s or less.

[0047] Component (F) is also preferably an alcohol-based volatile solvent (alcohol-based solvent). Examples of the alcohol-based solvent include ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and benzyl alcohol.

[0048] As the volatile solvent of component (F), ether-based solvents include diethyl ether and tetrahydrofuran. Ketone-based solvents include acetone and methyl ethyl ketone. Ester-based solvents include methyl acetate, ethyl acetate, butyl acetate, and isobutyl acetate. Hydrocarbon-based solvents include light liquid isoparaffin (mainly isoparaffin having 8 to 16 carbon atoms), pentane, isopentane, hexane, isohexane, heptane, isoheptane, decane, isodecane, dodecane, isododecane, tridecane, isotridecane, tetradecane, and isotetradecane.

[0049] As the component (F), one or more types can be used.

[0050] The content of component (F) (the total amount when multiple components are present) is not limited thereto, but from the viewpoint of obtaining coating film uniformity and good usability, it is preferably 0.01 to 60 mass%, more preferably 0.1 to 50 mass%, and even more preferably 1 to 30 mass% relative to the total amount of the composition (100 mass%).

[0051] Other ingredients: Water The composition may contain water. The composition may be an emulsion composition, in which case it may contain water. The emulsion form may be oil-in-water (O / W) or water-in-oil (W / O). In an emulsion composition, one of the internal phase and the external phase is the aqueous phase, and the other is the oil phase. The aqueous phase may contain water-soluble substances and hydrophilic substances. Alternatively, the composition may be a composition in which powders or the like are dispersed in a water-based solubilizing system. The composition may not contain water. The water is not limited to this, but purified water is preferably used.

[0052] When the present composition contains water, the content of water is not limited to this, but can be 1 to 70 mass %, preferably 5 to 60 mass %, and more preferably 10 to 50 mass %.

[0053] Other Ingredients The composition may contain various components that can be incorporated into UV protective cosmetics, such as oils (other than the above-mentioned volatile solvents), surfactants other than those mentioned above (nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants), polyhydric alcohols, moisturizers, thickeners, polymers, pigments, film-forming agents, pH adjusters, anti-fading agents, antioxidants, defoamers, powders, cosmetic ingredients, plant extracts, preservatives, fragrances, etc.

[0054] Here, in the present invention, it has been found that in an ultraviolet protective cosmetic composition containing both an ultraviolet absorbing agent and an ultraviolet scattering agent, by blending the above-mentioned spherical powder (component (C)) and silicone-based film-forming agent (component (D)), ultraviolet protection (particularly SPF value) can be improved without impairing the feeling of use, and a composition with high ultraviolet protection effect can be obtained, and the invention has been completed. Such an effect is further exhibited by combining, in particular, a silicone-based surfactant (component (E)) and a volatile solvent (component (F)). That is, as described above, in conventional ultraviolet protective cosmetics, increasing the blending amount of ultraviolet absorbing agent and ultraviolet scattering agent increases the ultraviolet protection effect, but tends to impair the feeling of use, such as stickiness and squeaking. However, it has been found that by combining the above-mentioned components (A) to (F), an ultraviolet protective cosmetic composition that achieves high functionality of ultraviolet protection while also having a good feeling of use can be obtained (see Examples).

[0055] Without being bound by theory, it is believed that the improvement of the UV protection effect is due to the fact that the coating film becomes uniform when applied to the skin, etc., by blending the spherical powder and the film-forming agent, and the UV absorber and the UV scattering agent can be dispersed and present in the uniform coating film. The blending of the spherical powder improves the dispersibility of the UV scattering agent, which can be composed of powder, and the solid components, the spherical powder and the UV scattering agent, can be uniformly present in the coating film, which is believed to improve the feeling of use. Furthermore, it is believed that the scattering by the spherical powder increases the amount of light that hits the UV absorber and the UV scattering agent, which is believed to improve the UV protection effect. In addition, the film-forming agent can form a film when applied to reduce the fluidity, so it is believed that it suppresses the localization of the powder components and contributes to a more uniform dispersion of the powder components. Furthermore, it is believed that the use of a silicone-based film-forming agent as the film-forming agent can suppress stickiness and provide a smooth feeling of use. In addition, by using silicone surfactant, the substance is compatible with silicone film-forming agent, so that silicone film-forming agent can be stably mixed in the formulation, and a uniform coating film can be formed when used, and stickiness can be suppressed.In addition, by mixing volatile solvent, volatile solvent evaporates when used, and a uniform coating film can be formed more quickly, so that powder components can be dispersed more uniformly, and ultraviolet protection effect can be improved.It should be noted that the above-mentioned action mechanism and mechanism are merely speculations, and the present invention is not limited thereto.

[0056] The present composition can be used as it is as an ultraviolet protective cosmetic composition, or the present composition can be used to obtain a final ultraviolet protective cosmetic composition by adding further appropriate ingredients or by partially removing the volatile solvent.

[0057] The present composition may be in the form of a water-in-oil emulsion cosmetic, an oil-in-water emulsion cosmetic, or a solid powder cosmetic (hereinafter collectively referred to as the present cosmetic). In the present cosmetic, by using the above-mentioned components (A) to (F), a cosmetic having a particularly good feel in use and excellent UV protection properties can be obtained in these forms. Note that a solid powder cosmetic is, for example, a cosmetic that contains a powder and is molded into a solid form.

[0058] The cosmetic of the present invention may be a skin cosmetic or a hair cosmetic. It is particularly preferable that the cosmetic of the present invention is a skin cosmetic (a cosmetic for the skin). The cosmetic of the present invention may be used as a cosmetic for various purposes requiring ultraviolet protection, including skin care products and makeup products.

[0059] The skin cosmetic is not particularly limited and can be used as a cosmetic for various purposes. For example, it can be a sunscreen, a makeup cosmetic, a foundation (e.g., liquid foundation, powder foundation, solid foundation, oil-based solid foundation), a pressed powder, a blush, an eye shadow, an eye color, a concealer, a face powder, a lipstick, a base (a makeup base), a skin care cosmetic, a milky lotion, a cream, and the like. The skin cosmetic can be used by applying it to hands or fingers, by using cotton, by impregnating nonwoven fabric, or by spraying or misting it.

[0060] The hair cosmetic is not particularly limited and can be used as a cosmetic for various purposes. For example, it can be a hair cream, a hair wax, a hair rinse, a hair mask, a hair treatment, a sunscreen for hair, a shampoo, a conditioner, etc. The method of using the hair cosmetic can be a method of applying it to hands or fingers, a method of spraying it with a spray or mist, etc.

[0061] The composition has an excellent ultraviolet protection effect and is particularly suitable for cosmetics to be used on parts of the body exposed to sunlight during the day (e.g., sunscreen, foundation, etc.). In particular, the composition can provide cosmetics with a good SPF (Sun Protection Factor) value. Furthermore, the composition can provide cosmetics with a good PA (Proteciton Grade of UVA) value.

[0062] The present composition can be produced by mixing the above-mentioned components. For example, in the case of an emulsion composition, an oily component that has been mixed in advance and an aqueous component that has been mixed can be mixed to emulsify the composition to obtain an emulsion composition. Alternatively, the composition may simply be mixed with the above-mentioned components. In the production, an appropriate emulsifier or kneader (e.g., a three-roller, homomixer, etc.) can be used. Of course, the method for producing the present composition is not limited to this. EXAMPLES

[0069] The examples and comparative examples shown in Tables 1 to 3 were produced by the following methods. Manufacturing Methods of Examples 1 to 18 (1) Component (B), component (C), a portion of component (E), and a portion of cyclomethicone (F) were mixed uniformly using a three-roll roller. (2) Dimethyl distearyl ammonium hectorite was swelled with a portion of component (E), a portion of the ethanol of component (F), and a portion of cyclomethicone. (3) Component (A), component (D), the remainder of component (E), the remainder of cyclomethicone (component (F)), and the above-mentioned (1) and (2) were mixed uniformly. (Note that in Example 2 only, component (A) was heated and dissolved at 90°C.) (4) The remaining ethanol of component (F) and water were added to the above (3) and emulsified to obtain a cosmetic preparation.

[0070] Manufacturing methods of Comparative Examples 1 to 13 In Comparative Example 1, a cosmetic preparation was obtained by producing in the same manner as in Example 1, except that components (C) and (D) were not blended (the same amounts were replaced with cyclomethicone). In Comparative Example 2, a cosmetic preparation was obtained by producing in the same manner as in Example 2, except that components (C) and (D) were not blended (the same amounts were replaced with cyclomethicone). In Comparative Example 3, a cosmetic preparation was obtained by producing in the same manner as in Example 4, except that components (C) and (D) were not blended (the same amounts were replaced with cyclomethicone). In Comparative Examples 4 and 5, cosmetics were obtained by producing them in the same manner as in Example 1, except that components (C) and (D) were not blended and the amount of component (B) was changed (the total blended amount was adjusted with cyclomethicone). In Comparative Example 6, a cosmetic preparation was obtained by producing in the same manner as in Example 1, except that component (A) was not blended (the same amount was replaced with cyclomethicone). In Comparative Example 7, a cosmetic preparation was obtained by producing in the same manner as in Example 1, except that component (B) was not blended (the same amount was replaced with cyclomethicone). In Comparative Examples 8 and 9, cosmetics were obtained by producing in the same manner as in Example 1, except that the amount of component (B) was changed (the total blended amount was adjusted with cyclomethicone). In Comparative Example 10, a cosmetic preparation was obtained by producing in the same manner as in Example 1, except that component (C) was not blended (the same amount was replaced with cyclomethicone). In Comparative Example 11, a cosmetic preparation was obtained by producing in the same manner as in Example 1, except that component (D) was not blended (the same amount was replaced with cyclomethicone). In Comparative Example 12, a cosmetic was obtained by producing in the same manner as in Example 1, except that polyglyceryl-10 pentaoleate was blended instead of component (E). In Comparative Example 13, a cosmetic preparation was obtained in the same manner as in Example 1, except that dimethicone was used instead of the component (F).

[0071] evaluation The cosmetics of the Examples and Comparative Examples shown in Tables 1 to 3 were evaluated by the following methods.

[0072] Non-sticky A panel of 20 experts conducted a usability test on each sample, and each panelist rated it on a four-level scale according to the absolute criteria below. The average score of all panelists was calculated and judged according to the following criteria. Specifically, the stickiness of the cosmetic product when an appropriate amount of each sample was spread on the skin was evaluated. (Absolute Standard) Stickiness 3: I can't feel it 2: Somewhat 1: Feel 0: Very sensitive (Judgment criteria) ◎: 2.5 points or more ○: 2 points or more and less than 2.5 points △: 1 point or more but less than 2 points ×: Less than 1 point

[0073] No creaking (grinding) A panel of 20 experts conducted a usability test on each sample, and each panelist rated it on a four-point scale using the absolute criteria below. The average score was calculated from the total scores of all panelists, and judged according to the following criteria. Specifically, an appropriate amount of each sample was applied to the skin, and the absence of any squeaking sensation (especially any powdery sensation) on the skin upon application was evaluated. (Absolute Standard) Creaking 3: I can't feel it 2: Somewhat 1: Feel 0: Very sensitive (Judgment criteria) ◎: 2.5 points or more ○: 2 points or more and less than 2.5 points △: 1 point or more but less than 2 points ×: Less than 1 point

[0074] Coating uniformity 0.1 g of each sample was placed on a glass plate, and a coating film was formed with a doctor blade to a thickness of 25 μm. The coating film was left for 3 hours, and then visually observed and rated according to the following criteria. ◎: 0 to 3 powder agglomerates were found ○: 4 to 6 powder agglomerates are observed △: 7 to 9 powder agglomerates were observed. ×: 10 or more powder aggregates were observed

[0075] UV protection effect The SPF value (in vitro) of each sample was measured using an SPF analyzer (Labsphere UV-2000S). The SPF value was compared with the SPF value of the control formulation, and the rate of change (%) (the rate of increase or decrease when the SPF value of the control formulation is set at 100) was calculated. Furthermore, the UV protection effect was evaluated (overall evaluation) according to the following criteria. ◎: SPF value improved by 30% or more compared to the control formulation 〇: SPF value improved by 20% to less than 30% compared to the control formulation △: SPF value improved by 10% to less than 20% compared to the control formulation ×: SPF value improved by less than 10% from the control formulation, or did not improve at all The "comparison preparation" is a preparation that serves as a control for comparison, and in the examples and comparative examples to be evaluated, it means a preparation that does not contain component (C) and component (D), and has the same composition as component (A) and component (B), and corresponds to any of the comparative examples 1 to 5 (listed in the table). Comparative examples 1 to 5 are preparations used as a comparison control, so they do not have a comparison preparation.

[0076] result Examples 1 to 18 containing components (A) to (F) were good in terms of UV protection effect, coating uniformity, and usability (non-stickiness, non-squeakiness) (there were no evaluations of ×, and most were better than △, and most were better than ◯). On the other hand, Comparative Examples 1 to 13 were evaluated as × in any of the items, and good preparations were not obtained.

[0077] Specifically, Comparative Examples 1 to 3, which did not contain components (C) and (D), had poor coating uniformity. In contrast, Examples 1 to 18 all had good coating uniformity and improved SPF values ​​compared to the comparative control formulations (Comparative Examples 1 to 3). Comparative Example 4, which did not contain components (C) and (D) and had a content ratio ((A) / (B)) of components (A) and (B) exceeding 5, was sticky and had a low SPF value. Furthermore, Comparative Example 8, which corresponds to the composition of Comparative Example 4 plus components (C) and (D), had a slightly improved SPF value compared to Comparative Example 4, but was still sticky. In addition, Comparative Example 5, which did not contain components (C) and (D) and had a content ratio ((A) / (B)) of components (A) and (B) of less than 0.6, had a relatively high SPF value, but the coating film was poor in uniformity and had squeaky sound. Furthermore, in Comparative Example 9, which corresponds to the composition of Comparative Example 5 to which components (C) and (D) were added, the SPF value was slightly improved compared to Comparative Example 5, but the coating film still had poor uniformity and squeaky sound. Comparative Example 6, which did not contain component (A), and Comparative Example 7, which did not contain component (B), had low SPF values. In Comparative Example 10, which did not contain component (C), and Comparative Example 11, which did not contain component (D), the SPF value was hardly improved from the comparative control formulation (Comparative Example 1), suggesting that the incorporation of both components (C) and (D) is advantageous for improving the SPF value. In addition, the SPF values ​​of Comparative Example 12, which did not contain component (E), and Comparative Example 13, which did not contain component (F) (dimethicone was used as a non-volatile solvent instead of component (F)), also showed little improvement over the control formulation (Comparative Example 1).

In the following examples, the content means the blending ratio (mass%), and the "balance" means the amount that makes the total amount 100 mass%. In the following formulation examples, component (B) (hereinafter referred to as "component B") is not a spherical powder, except when explicitly stated (such as component 14 in formulation example 1).
