Abstract
The invention provides a powder-containing cosmetic which has no burden feeling when being applied on the skin, particularly uniformly and naturally hides spots and uneven skin color, does not feel dry feeling even after a long time, continuously and uniformly coats and has high ultraviolet shielding capability. The present invention relates to a powder-containing cosmetic composition containing a composite powder having no brilliance, which is obtained by coating a mica surface with titanium oxide in a layered manner and further with iron oxide, a spherical powder having a specific size, and titanium oxide and/or zinc oxide having a specific particle size.
Description
Technical Field
The present invention relates to a powder-containing cosmetic material containing: a composite powder having no brilliance, which is obtained by coating a mica surface with titanium oxide and further iron oxide in a layered manner, a spherical powder having a specific size, and titanium oxide having a specific particle diameter; more specifically, the present invention relates to a powder-containing cosmetic which gives no feeling of burden when applied to the skin, in particular, gives uniform natural coverage of spots and uneven skin color, gives no feeling of dryness over a long period of time, gives a continuous uniform finish, and has high blocking ability in the ultraviolet region.
Background
Conventionally, various covering powders have been developed and studied in combination with cosmetics containing powders for the purpose of naturally and uniformly covering makeup with respect to skin unevenness such as high level of consumer annoyance, spots such as liver spots and senile plaques, and acne marks. In particular, titanium oxide is widely used as a covering powder because of its high diopter strength and excellent whiteness and coloring power, and also widely used for the purpose of having an ultraviolet ray shielding effect. On the other hand, iron oxide is widely used as a coloring pigment for toning in order to conform to various human skins.
For example, in order to achieve the object of having an ultraviolet shielding effect and also having excellent moldability, the following solid powder cosmetics have been developed: by using a plate-like powder having an aspect ratio of 10 or more, which is not glittering, with two or more of these kinds of powder coated on the surface of mica, the mottle and uneven skin color are naturally hidden, and the skin is protected from ultraviolet rays (see, for example, patent document 1). Further, a powder cosmetic excellent in ultraviolet screening effect and usability has been developed by blending a plate-like powder coated with a fine inorganic particle powder having a high ultraviolet screening effect with a spherical powder coated with the same fine inorganic particle powder (for example, see patent document 2). Moreover, solid powder cosmetics have been developed which have the following cosmetic effects: a cosmetic using a composite powder in which a plate-like powder is coated with a metal oxide having a limited particle size has no squeak or powdery feel and no dullness and has a transparent feel after coating (see, for example, patent document 3).
On the other hand, in order to achieve natural makeup and to have a covering property, a powder in which an iron oxide is coated on a surface of titanium oxide having a specific particle diameter has been developed, and a makeup cosmetic material in which a makeup film has a covering power, is white and does not go unnaturalness, and is less dark in color due to long-term wetting has been developed (for example, see patent document 4).
Further, as a powder for masking irregularities of skin such as pores and spots, spherical powders having various particle diameters and compositions have been developed, spherical cellulose powders having a soft-focus effect have been developed by diffusion and reflection of visible light, and cosmetics having a smooth feeling and excellent long-term stability without sticky feeling have been developed (for example, see patent document 5).

Disclosure of Invention
Problems to be solved by the invention
However, in the conventional technique of patent document 1, as a method of coating titanium oxide on plate-like mica, a method of mixing and fixing titanium oxide and mica using a bead mill or the like is used, but titanium oxide does not uniformly coat the mica surface, and there is a case where the feeling of ultraviolet shielding ability or no burden is poor, and there is room for further improvement in the coating method or the composition constituting the composite powder. Further, in patent documents 2 and 3, since the fine inorganic particles coated on the plate-like powder are in a specific granular form and have inferior surface smoothness as compared with a layer-like coating, the application property is inferior, the oil absorption is high, a dry feeling is felt, and it is difficult to uniformly arrange the fine inorganic particles on the skin surface. It is desired to develop a plate-like powder which can be smoothly applied to the skin and does not feel dry, and which is a layer-coated metal oxide that exhibits the maximum ultraviolet shielding ability and does not have a brilliant effect.
On the other hand, in the iron oxide-coated titanium oxide in which spots or uneven skin color are naturally hidden according to the prior art of patent document 4, when it is desired that the powder-containing cosmetic has a higher ultraviolet shielding ability, the function can be improved by combining the powder-containing cosmetic with a fine particle-shaped metal oxide because the monomer is poorly mixed, but the powder-containing cosmetic has a feeling of burden of smearing and unnatural makeup, and therefore it is desired to develop a powder-containing cosmetic that can achieve both natural makeup and a high ultraviolet shielding ability.
In addition, in the prior art of patent document 5, it is studied to repair pores or irregularities and absorb sebum secreted for a long time to make up uniformly, but the following problems are not studied vigorously: these powders are easily selectively present in the recesses of the skin by combining with other applied powders, and effectively absorb sebum in pores, thereby reducing the feeling of dryness of the protrusions.
As described above, the conventional techniques do not consider various surface shape controls that can exhibit various effects and promote appropriate placement of powder on the skin.

Modes for carrying out the invention
Preferred embodiments of the present invention will be described in detail. However, the present invention is not limited to the following preferred embodiments, and may be freely changed within the scope of the present invention. In the present specification, percentages are expressed by mass unless otherwise specified. In addition, in the present specification, when a numerical range is expressed, the range includes numerical values at both ends. The "average particle diameter" in the present invention is a value (median diameter D50) obtained by observing the surface state with a scanning electron microscope (JSM-7800 prime, manufactured by japan electronics) and measuring the particle diameter with an image analyzer (ルーゼックス AP, ニレコ), and refers to the major diameter of the particle.
The component (A) used in the present invention is a plate-like composite powder having no brilliance, and a composite powder in which the surface of mica is layered with 30 to 50 mass% of titanium oxide and further with 0.1 to 3 mass% of iron oxide, can be applied uniformly for a long period of time without feeling dry, and has a high ultraviolet-shielding effect.
Mica, which is a mother powder of the plate-like composite powder of component (a) of the present invention, has a plate shape, and includes: examples of the mica include natural mica such as phlogopite and muscovite, and particularly synthetic mica such as (fluoridized/hydroxylated/oxidized)/(Mg/K/silicon). The aspect ratio is preferably 10 to 50, more preferably 10 to 30, and when the aspect ratio is small, the amount of titanium oxide to be coated is small, and thus the ultraviolet shielding effect is poor, the orientation to a skin dome is reduced, and a uniform cosmetic film is poor. Further, when the aspect ratio is large, the bulk specific gravity becomes high, and therefore, the blending amount of the cosmetic containing the powder is limited.
Among them, sericite (serilite) which has high whiteness and hardly causes brilliance in the case of layer-forming composite, or synthetic phlogopite which undergoes little color change when immersed in an oil solution and can control brilliance and adhesion of metal oxide on the treated surface in coating is preferable, and sericite which can be purchased at low cost is particularly preferable.
The method for coating the titanium oxide of the component (a) of the present invention on mica is different from the following method (hereinafter, collectively referred to as an adsorption method): the titanium oxide or iron oxide prepared in advance is mechanochemical fixed (adsorbed) on the surface or the dispersed solvent is sprayed and adsorbed by using a mechanical force such as a bead mill, a henschel mixer, or a pulverizer; but a method of densely depositing titanium oxide on the surface of mica (hereinafter referred to as a deposition method). For example, a method in which mica is suspended in a strongly acidic solution of dilute titanyl sulfate at ambient temperature, rapidly heated to 90 to 100 ℃ and maintained at that temperature for about 2 to 3 hours, and a hydrous oxide layer is precipitated on a substrate by hydrolyzing the titanium sulfate solution; or a method in which the substrate is suspended in hot water, and a strongly acidic concentrated sulfuric acid titanyl solution is rapidly added to the substrate, and the hot water is continuously heated until the hydrolysis is completed, thereby causing hydrolysis and precipitation of mica with titanium hydroxide. Since titanium oxide having ultraviolet shielding ability can be layered on the entire surface of the plate-like mica by these precipitation methods, a composite powder which is free from aggregation of titanium oxide and is free from feeling of burden can be obtained as compared with the conventional adsorption method.
Titanium oxide is preferably contained in an amount of 30 to 50% in the component (a) of the present invention, and when the amount is small, the ultraviolet shielding effect is poor, and when the amount exceeds 50%, an excessive amount is formed on the mica surface, and a uniform layer is hardly formed and the composition cannot be made, and the titanium oxide may be precipitated as particles alone. In this case, the feeling of application is poor, the composite powder aggregates, and effective ultraviolet shielding ability cannot be obtained, and it is difficult to smoothly distribute the powder on the skin, and a uniform hiding effect cannot be expected, and a dry feeling may be felt. The layer coating means that titanium oxide on the mica surface does not form a particle shape on the mica surface. The thickness of the titanium oxide layer is preferably 50 to 100nm, and a smooth layer with less unevenness is preferable, but the thickness is not particularly limited. If the thickness of the layer is within the range, the covering power is hard to generate, the efficiency of the ultraviolet shielding effect is high, uniform smearing is easy to realize particularly in a skin dome, the unevenness is small, the oil absorption is hard to be high, and therefore, the dry feeling can be reduced in the skin dome which is easy to feel dry.
Further, as a method of further coating the mica coated with the titanium oxide of the component (A) of the present invention with iron oxide, the method may be a dry method, a wet method or the like, and is not particularly limited, and for example, after a slurry of the coated pigment is uniformly dispersed in an aqueous solution of a water-soluble iron salt (ferrous chloride, ferric chloride, ferrous sulfate, ferric sulfate, ferrous nitrate, ferric nitrate or the like), slowly adding an aqueous solution of sodium acetate while stirring to adjust the pH to 3-5, heating to a temperature of more than 60 ℃ to hydrolyze the iron salt, thereby selectively precipitating an amorphous hydrous oxide on the particle surface of the coated pigment, adding an aqueous alkali solution to the mixture at a stage of color change, adjusting the pH of the mixture to 8-9.5 while heating the mixture, and thereafter, the iron oxide-coated titanium oxide-coated mica can be obtained by a method such as filtration, washing with water, drying, or sintering and pulverization.
The amount of iron oxide in the component (a) of the present invention is not particularly limited, but the lower limit is preferably 0.1% or more, more preferably 1.0% or more, and still more preferably 1.5%. The upper limit is preferably 5% or less, more preferably 3%, and still more preferably 2.5%. Within this range, the bluish white of the composite powder itself is reduced, and a natural color tone more suitable for the skin can be obtained. In addition, in the cosmetic containing the powder, the amount of iron oxide blended for other uses is reduced, the cohesiveness of iron oxide can be reduced, and the ultraviolet shielding effect can be improved, particularly in the UVA region. Further, when 0.1 to 4% by mass of zinc oxide is coated, the ultraviolet shielding effect is further improved, the corrosion resistance is also improved, and a metal soap is likely to be formed even when the zinc oxide is reacted with a surface treatment agent, and thus a further excellent effect can be provided. In this coating range, the cohesive force of zinc oxide does not prevent uniform application, and therefore, it is more preferable.
As a method for measuring the surface treatment of a metal, for example, the surface treatment amount of each metal contained in a sample (powder) can be measured by ICP (Inductively Coupled Plasma; ARCOS (r スペクトロ corporation)) luminescence analysis using a general method.
The component (a) of the present invention has no brilliance, but the brilliance can be determined and defined by the following measurement method, for example. Specifically, a 40mm wide double-faced adhesive manufactured by ニチバン was applied to the black part of OPACITYCHARTS manufactured by LENETA, and the composite powder was uniformly coated with a cosmetic puff. The coated sample was fixed at an incident angle of 45 degrees using a digital variable angle gloss meter manufactured by スガ testing machine, and the gloss intensity at 20 degrees (I20) and the gloss intensity at 45 degrees (I45) at the light receiving angle were measured to calculate I45/I20, and the ratio of them was set to be I45/I20
I45/I25 is 2.0 or more: has bright property
I45/I25 is not more than 2.0: has no brilliance.
The UV transmittance of the component (a) composite powder of the present invention was evaluated under the following conditions. The composite powder of component (a) was added to a nitrocellulose solution of 43.4% butyl acetate, 21.0% ethyl acetate, 14.6% IPA, and 21.0% nitrocellulose to a concentration of 40%, and then dispersed at a dispersion speed of 3000rpm for 10 minutes. Then, a coating film was formed on a quartz plate from the dispersion by using a doctor blade (thickness of 12 μm) to have the same thickness, and the transmittance of the coating film in the wavelength range of 250 to 700nm was measured using a spectrophotometer (manufactured by U-4100 HITACHI). The evaluation of the blocking ability in the UVA region of 320-400 nm is performed by using a transmittance of 360nm, and the evaluation of the blocking ability in the UVB region of 280-320 nm is performed by using a transmittance of 300 nm. The transmittance is preferably less than 50%, and more preferably less than 25%.
Further, the average particle size of the component (a) of the present invention is not particularly limited. The lower limit is preferably 3 μm or more, and the upper limit is preferably 30 μm or less, and more preferably 20 μm or less. In particular, the particle size distribution is concentrated, but a uniform cosmetic film is easily formed, which is more preferable.
Further, the component (a) of the present invention is more preferably low in oil absorption. The oil absorption of the present invention is defined as the oil absorption of triisocaprylic glyceride which is a triglyceride similar to sebum, and the measurement method is based on JIS K5105, wherein triisocaprylic glyceride which is one of the cortical components is gradually added to 100g of spherical powder instead of linseed oil, and the end point is reached when the spherical powder is made into a slurry. Specifically, the amount is not particularly limited, but is preferably 100ml/100g or less, more preferably 70ml/100g or less. The component (a) of the present invention is a material which is easily attached to smooth convex portions of the skin because it is plate-shaped, but the mica of the matrix is thin and the surface of the mica is compounded with a metal oxide, so that the oil absorption per unit weight is easily increased, which tends to be the same. When the oil absorption amount is too high, a dry feeling is easily felt by removing sebum on the skin surface, and the amount of the cosmetic composition blended or the surface treatment amount becomes excessive, and therefore, it may be necessary to appropriately adjust the amount.
Therefore, the component (a) of the present invention can be applied smoothly and reduce the dry feeling by the water-transfer surface treatment, and the makeup sustainability can be further improved. The hydrophobizing agent is not particularly limited, but is described in detail in the following summary.
The lower limit of the amount of the powder-containing cosmetic ingredient (a) used in the present invention is preferably 1% or more, more preferably 3% or more, and still more preferably 5% or more. The upper limit is preferably 50% or less, more preferably 30% or less, and still more preferably 15% or less. In this range, the ultraviolet shielding effect, natural makeup, and no dry feeling are particularly preferable.
The spherical powder of the component (B) used in the present invention has an average particle diameter of 1 to 40 μm. Spherical means the ratio of the major axis to the minor axis: the major/minor diameters are 1 to 1.5, and particularly, even if the surface has fine irregularities, the inside does not have a void. The lower limit is an average particle diameter of 1 μm or more, preferably 3 μm or more, and the upper limit is 40 μm or less, preferably 30 μm or less. When the average particle size is less than 1 μm, the flocculation property in the furrows is increased, and the effect of hiding unevenness such as pores and spots is poor, and when it exceeds 40 μm, the spreadability is poor, and the scattering is caused, and the makeup sustainability is poor, which is not preferable. The material is not particularly limited, and includes: nylon powder, polystyrene powder, polyethylene powder, polymethyl methacrylate resin powder, silicone resin powder, polyurethane powder, cellulose acetate powder, silk powder, starch, calcium alginate, silicone, urethane and other organic powders, silica, calcium carbonate and other inorganic powders. In view of the background of environmental problems of plastic microparticles in recent years, the incorporation of spherical cellulose, silica, calcium carbonate, and starch is particularly preferable.
Further, the metal oxide may be compounded on the surface of the component (B), and preferably, particles of 10 to 1200nm are precipitated or adsorbed on the surface, or may be included in the component (B). The metal oxide is not particularly limited, and preferable examples thereof include: titanium oxide, zinc oxide, aluminum oxide, and cerium oxide, the component (C) may be previously compounded with the component (B).
The amount of the component (B) in the present invention is not particularly limited, but the lower limit is preferably 0.5% or more, more preferably 2% or more, and still more preferably 5% or more. The upper limit is preferably 30% or less, more preferably 25% or less, and still more preferably 20% or less. Within this range, the cosmetic composition can enter the recesses of the skin, and can maintain a uniform cosmetic film while absorbing sebum while leaving irregularities.
The oil absorption of the spherical powder of component (B) is not particularly limited, but the oil absorption of sebum-like triglyceride or triisocaprylic acid glyceride is preferably 60ml/100g or more as the lower limit, more preferably 70ml/100g or more as the upper limit, and is preferably 350ml/100g or less, and further preferably 200ml/100g or less as the upper limit. In the case of this range, the spherical powder oriented near the pores in the furrows has a moderate sebum absorption, is excellent in the durability of the makeup, and does not absorb sebum more than necessary, so that the feeling of dryness is not felt. A porous powder is preferable. However, the dry feel may be adjusted by absorbing oil in advance, or may be adjusted by using a surface treatment agent or the like. For example, in the case of silicone resin powder, KSP-100 (oil absorption: 80ml/100g) (manufactured by shin-Etsu chemical Co., Ltd.) and in the case of polyurethane powder, for example, CS-400 (oil absorption: 90ml/100g) (manufactured by shin-Etsu chemical Co., Ltd.) are used as plastic powder, examples of the silica include God ball D11-796C (oil absorption: 83-89ml/100g), God ball E-90C (110-, examples of the crosslinked polymethyl methacrylate include MBP-8 (oil absorption 140ml/100g) (manufactured by Hydrochemical industries, Ltd.), examples of the spherical cellulose include CELLULOBEADS D-10 (oil absorption: 150ml/100g) (manufactured by Dadonghuachen chemical industries, Ltd.).
The coated titanium oxide and/or zinc oxide of the component (C) is 1 or 2 kinds of titanium oxide and/or zinc oxide coated with an oxide or hydroxide of silicon, an oxide or hydroxide of aluminum, and an oxide or strong oxide of iron. The particles of titanium oxide and/or zinc oxide, which are coated with the parent nucleus of titanium oxide and/or zinc oxide of the present invention, are not particularly limited in shape, and may be titanium oxide alone, zinc oxide contained in titanium oxide, or zinc oxide alone (hereinafter referred to as parent nucleus).
The titanium oxide of the core before coating in the titanium oxide and/or zinc oxide to be coated of the component (C) may be obtained by a known method for producing a titanium oxide powder, or may be a commercially available product. Further, titanium oxide as a mother nucleus has anatase type and rutile type crystal forms, but a rutile type having a high hiding power is suitable because the photocatalytic activity is low and the refractive index is high.
Alternatively, in order to stabilize the crystal shape, it is preferable that a small amount of zinc oxide is contained in the titanium oxide powder as the matrix, and the content of zinc oxide in the titanium oxide as the matrix is preferably 1 mass% or less, more preferably 0.1 to 0.8 mass%, and further preferably 0.2 to 0.7 mass% in terms of the mass of the oxide.
Alternatively, zinc oxide as a mother nucleus may be used alone. The zinc oxide can be obtained by a known method for producing zinc oxide.
The shape of the titanium oxide and/or zinc oxide as the parent nucleus of the component (C) is not particularly limited, and examples thereof include: straw, ribbon, sphere, needle, rod, plate, etc. Among these, titanium oxide and/or zinc oxide used as the parent nucleus of the present invention is preferably spherical or plate-like with a relatively smooth surface.
The titanium oxide and/or zinc oxide to be coated of the component (C) is preferably coated with a surface treatment amount of each metal in a specific range described below. Through in this scope, can obtain the natural third dimension of skin better, and then can reduce the bluish white and the yellow darkness of skin more, can bring natural even hidden effect. The surface treatment amount of aluminum in the coated titanium oxide and/or zinc oxide of the component (C) is preferably 1 to 6%, more preferably 1 to 5%, and further preferably 2 to 5% in terms of the oxide amount. The amount of surface treatment of silicon is preferably 0.5 to 6%, more preferably 1 to 6%, and further preferably 3 to 6% in terms of the amount of oxide. The surface treatment amount of iron is preferably 0.5 to 3%, more preferably 0.5 to 2%, and further preferably 0.5 to 1.5% in terms of the amount of oxide.
In the powder-containing cosmetic of the present invention, the content of the component (C) is preferably 0.5% or more, more preferably 3% or more, and still more preferably 5% or more, as the lower limit value thereof. The upper limit value is preferably 30% or less, more preferably 20% or less, and still more preferably 15% or less.
The component (C) is preferably coated with an oxide or hydroxide of silicon on the surface of the mother core, and therefore has improved dispersibility and uniform hiding power, and is more preferably coated with an oxide or hydroxide of aluminum or an oxide or hydroxide of iron. Further, it is more preferable to have 3 kinds of these layers (hereinafter, each of these layers is referred to as "silicon coating layer", "aluminum coating layer", and "iron coating layer", respectively). On the surface of the particle in which the silicon coating layer and the aluminum coating layer are mixed, an oxide or a hydroxide of coated iron is more preferable. The coating layers are mixed together on the surface to form a natural makeup, and the makeup is good in spreadability and can realize uniform hiding power. That is, by controlling the coating layer, the change in surface charge can be controlled, and the adsorption sites of various surface treatment agents can be formed, and the dispersibility in the cosmetic containing powder is good. As a result, the component (C) can be uniformly dispersed regardless of the unevenness of the skin, and can be suitably attached to and dispersed on the surface of the component (a) or (B) without hindering the application of the component (a) or (B), thereby providing a synergistic effect of uniform hiding power. Particularly, the iron coating layer is preferable because it increases skin affinity for skin color, has a natural makeup effect even with hiding power, and hardly causes the cosmetic film to break, and thus the makeup lasting effect is enhanced.
The method for coating the silicon oxide or hydroxide of the component (C) is not particularly limited, and a known coating method can be used. For example, there may be mentioned: a method in which sodium silicate or the like is directly added to an aqueous slurry containing raw material particles or added as an aqueous solution, and then an acid such as sulfuric acid is added to precipitate silica or a hydrate thereof; or a method in which raw material particles are dispersed in a solvent (alcohol, water, or a solvent mixture of alcohol and water), an alkoxysilane-based metal coupling agent such as tetraethoxysilane is added, an acid or alkali is added, and silica or a hydroxide thereof is precipitated by heating or the like. Thereafter, the coated powder particles are obtained by washing, filtering, drying, and the like.

The obtained complex hydrate is washed, neutralized and dried. And (c) pulverizing the raw material particles, and then sintering the raw material particles and the iron oxide or hydroxide (for example, at about 750 to 900 ℃ for about 1 to 3 hours). Examples of the iron compound include: iron oxide, ferrous oxide, ferroferric oxide, ferric hydroxide, ferric organic acid (e.g., ferric oxalate, ferric citrate), ferric inorganic acid (e.g., ferric chloride, ferric sulfate), etc., and 1 or 2 or more of them may be selected. The iron compound is present in the particles as iron oxide or iron hydroxide.
In the coated titanium oxide and/or zinc oxide of the component (C), the lower limit of the average particle diameter D50 according to the transmission electron microscope image analysis method is preferably 0.10 μm or more, more preferably 0.20 μm or more, and still more preferably 0.25 μm or more. The upper limit is preferably 1.20 μm or less, more preferably 1.00 μm or less, still more preferably 0.8 μm or less, and still more preferably 0.50 μm or less. By using such a particle size, the cosmetic can be easily applied to the skin, can be naturally applied, and can provide uniform hiding power and cosmetic sustainability.
The component (a), the component (B), and the component (C) of the present invention may be further subjected to a surface treatment within a range not to impair the effects of the present invention. By performing the surface treatment, it is possible to impart a makeup retention, a use property, and the like associated with viscosity, oil dispersibility, water repellency, and the like. The surface treatment can be performed by a known powder surface treatment method. The surface treatment for water repellency and/or oil repellency may be performed by, for example, a silicone compound (e.g., dimethylpolysiloxane, methylhydrogenpolysiloxane, etc.), a coupling agent (e.g., silanes such as alkylalkoxysilane treatment, aluminum-based, titanium-based, etc.), a fluorine compound (e.g., perfluoroalkylalkoxysilane treatment), a hydrocarbon compound, lecithin, hydrogenated lecithin, an amino acid, a peptide, an amino acid derivative (e.g., as N-acylamino acid treatment, lauroyl lysine treatment, dilauroyl glutamic acid lysine Na treatment, stearoyl glutamic acid 2Na treatment, lauroyl aspartic acid Na treatment), polyethylene, a wax, a fatty acid (e.g., stearic acid, palmitic acid, myristic acid) · fatty acid salt/fatty acid ester/fatty acid amide, a metal soap, or the like.

Table 1 shows the evaluation method and the evaluation result of the material as the component (a).
[ TABLE 1 ]
(mass%)
Production examples 1 to 9: produced by the precipitation method a. The aspect ratio of the matrix was 20 to 30 in production examples 1 to 3 and 5 to 8, 10 to 20 in production example 4, and 68 in production example 9. Oil absorption was 65ml/100g in production example 4. The production example 5 was 65ml/100 g.
Production of comparative example 1: the resin composition was produced by adsorption method B (mixing with a high-speed Henschel mixer at 3000rpm, and pulverizing with a pulverizer). MT-500B (manufactured by Delika (テイカ)), MZ-300 (manufactured by Delika (テイカ)), Mitsubishi sericite (サンシンセリサイト) FSE (manufactured by Mitsubishi mining Co., Ltd.), and isostearic acid were mixed in an amount of 3%.
Comparative example 2 was produced: the same adsorption method B as in comparative example 1 was used. A titanium oxide component having an average particle diameter of 15nm of MT-150EX (manufactured by テイカ Co., Ltd.), 40% of TRY-100HP 1%, 0.5% of TRR-100HP, 0.32% of industrial company (manufactured by チタン Co., Ltd.), and sericite LQ-15 (manufactured by オーケム Co., Ltd.) were mixed. The oil absorption was 80ml/100 g.
Production of comparative example 3: cover leaf PC-2035M (manufactured by catalytic chemical industries Co., Ltd.)
Production comparative example 4: STA-20C (manufactured by ジャパンセリサイト Co.), Master (Mitsubishi sericite (サンシンセリサイト) FSE (manufactured by Japan sericite (ジャパンセリサイト Co.))
Production of comparative example 5: blondii Metallic Gold N-2000S (CQV Co., Ltd.)
The surface state of the iron oxide/titanium oxide-coated plate-like mica prepared by the precipitation method of the component (a) of the present invention (production example 6) was observed with a scanning electron microscope (JSM-7800 prime, manufactured by japan electronics) at an acceleration voltage of 5kV and at a magnification of 5000 to 100000 times, and the photograph is shown in fig. 1. As a detailed explanation of FIG. 1, a portion where a titanium oxide layer deposited on the surface of mica of the mother body is partially peeled off was prepared, and the thickness of the titanium oxide layer at 20 places was enlarged and confirmed to be 50 to 100 nm. Further, as a result of element mapping (mapping) of the composite powder of the component (a) using energy dispersive X-ray analysis (X-MAX manufactured by オックスフォート) at an acceleration voltage of 10kV, it was found that Ti elements were present uniformly throughout, and further, since the powder present in the form of dots on the surface thereof was Fe elements, it was confirmed that the powder present in the form of dots was iron oxide.
On the other hand, mica coated with zinc oxide and titanium oxide prepared by a mechanochemical method (comparative example 1) is shown in FIG. 2. As a detailed explanation of fig. 2, zinc oxide and titanium oxide have an uneven shape and are fixed to the surface of mica as a matrix in a particle shape. Further, as a result of element mapping using energy dispersive X-ray analysis (EDX), it was found that titanium oxide and zinc oxide were unevenly fixed to the surface because Ti element and Zn element were present in spots.
[ evaluation method: UVB transmittance (300nm) and UVA transmittance (360nm)
The ultraviolet-shielding ability of the composite powder of component (a) of the present invention was evaluated under the following conditions. First, a composite powder of the component (a) was added to a nitrocellulose solution of 43.4% butyl acetate, 21.0% ethyl acetate, 14.6% IPA, and 21.0% nitrocellulose to a concentration of 40%, and then dispersed at a dispersion speed of 3000rpm for 10 minutes. Then, a coating film was formed on a quartz plate from the dispersion by using a doctor blade (thickness of 12 μm) to have the same thickness, and the transmittance of the coating film in the wavelength range of 250 to 700nm was measured using a spectrophotometer (manufactured by U-4100HITACHI Co., Ltd.) for the dried coating film. The blocking ability in a wide range from UVB to UVA is evaluated by using a transmittance of 360nm as the evaluation of the blocking ability in a UVA region of 320 to 400nm and a transmittance of 300nm as the evaluation of the blocking ability in a UVB region of 280 to 320 nm. The results of evaluation of each composite powder and its transmittance and shielding ability are shown in table 1. Evaluation level the evaluation was performed at the following levels.
[ evaluation references ]
Very good: the transmittance is less than 25%. (very good: transmittance less than 20%)
O: the transmittance is more than 25 percent and less than 50 percent
Δ: the transmittance is more than 50 percent and less than 75 percent
X: the transmittance is more than 75 percent and less than 100 percent
From table 1, it is understood that the composite powder of component (a) prepared by the precipitation method (production method a) of production examples 1 to 9 can block UVB to UVA in a wide range. These are presumed to be because the titanium oxide layer is uniformly and densely coated on the surface of mica, and further coated with iron oxide, as shown in fig. 1. On the other hand, the zinc oxide-titanium oxide-coated plate mica and the titanium oxide-coated mica prepared by the adsorption method (production method B) of production comparative examples 1 and 2 had poor shielding ability from UVB to UVA because titanium oxide and zinc oxide were not uniformly fixed to the surface of mica. In production comparative examples 3 and 4 prepared by the precipitation method (production method a), titanium oxide exists in a particulate form, and the iron oxide/titanium oxide-coated plate mica has the brilliance of production comparative example 5, and has poor UVB to UVA blocking ability.
[ evaluation method: even application without hiding power
Further, even application of each powder was carried out without covering power, and 20 cosmetic evaluation groups were evaluated on a 5-grade basis according to the following criteria, and each composite powder was scored for spreading on a certain area of skin, and the average score of all the group scores was determined according to the following criteria.
[ evaluation criteria ]:
(evaluation results): (rating)
Very good: 5 points of
Good: 4 is divided into
The method comprises the following steps: 3 points of
Slightly bad: 2 is divided into
Not good: 1 minute (1)
[ decision criteria ]:
(average score of scores): (judgment)
4.0 or more: very good
3.0 or more and less than 4.0: o-
1.5 or more and less than 3.0: delta
Less than 1.5: is prepared from
According to table 1, the composite powders of production examples 1 to 9 were excellent in uniform application and non-covering power. In production comparative examples 1 and 2, titanium oxide and zinc oxide were fixed in a particle form on the surface of mica, and therefore, the particles had large irregularities, a squeak feeling and a powdery feeling, and could not be uniformly applied, and the particles were partially aggregated, so that the masking power was easily exhibited. Although the production comparative examples 3, 4 and 5 were uniformly coated, the ultraviolet shielding ability was low, and the hiding power was particularly easy to develop because the production comparative example 5 had a bright property.
A foundation having the composition shown in tables 2 and 3 was prepared by the following production method. All the obtained foundations were evaluated for "feeling of burden when not applied to the skin", "effect of uniformly hiding spots and color unevenness", "natural makeup", "no long-time dry feeling", "makeup continuation effect", and "ultraviolet shielding effect" by the following evaluation methods.

[ evaluation: "feeling of burden on skin during application", "effect of uniformly hiding spots and uneven skin color", "natural makeup", "feeling of dryness over a long period of time", "effect of maintaining makeup" ]
Using the foundations of examples 1 to 16 and comparative examples 1 to 9, 20 cosmetic evaluation groups were evaluated for "feeling of burden when not applied to the skin", "effect of uniformly hiding spots and uneven skin color", "natural makeup", "makeup continuation effect" on 5 grades according to the following criteria, and each foundation was scored, and further the average score of all the group scores was determined according to the following criteria. Further, as the "makeup sustainability effect", a state 6 hours after the start of foundation application (daily life) was evaluated in comparison with a state immediately after application.

[ evaluation: "ultraviolet ray shielding effect" ]
The foundations of examples 1 to 16 and comparative examples 1 to 9 were set at 2mg/cm2After coating on a PMMA plate, the plate was left to stand for 20 minutes to obtain a sample, and SPF was measured using an SPF analyzer (UV-2000S manufactured by Labsphere).
(a) Evaluation criteria of grade 4
(evaluation): (judgment)
SPF value is 20 or more: very good
The SPF value is more than 15 and less than 20: o-
The SPF value is more than 8 and less than 15: delta
SPF value less than 8: is prepared from
As is clear from the results in table 2, the foundations of examples 1 to 16, which are the products of the present invention, are excellent powder cosmetics in all items of "feeling of burden when not applied to the skin", "effect of uniformly hiding spots and uneven skin color", "natural makeup", "no feeling of drying for a long time", "makeup continuation effect", and "ultraviolet shielding effect".
On the other hand, as is clear from the results in table 3, the results are: in comparative example 1 in which the component (a) was not blended, and comparative examples 2 and 3 in which comparative examples 2 and 4 were blended instead of the component (a), the "effect of uniformly hiding spots and uneven skin color", "makeup continuation effect", and "ultraviolet shielding effect" were low. Further, comparative example 4, which contained the fine-particle metal oxide and the component (D) instead of the component (a), was inferior in "feeling of no burden on the skin upon application", "natural makeup", "feeling of no dryness for a long time", "effect of continuation of makeup". This is presumed to be because none of them can uniformly coat the component (a) in the skin dome, and the hiding effect of the component (a) is not obtained, and the cosmetic effect thereof is lowered. Comparative example 5 containing no component (C) and instead containing a metal oxide was unsatisfactory in the effects of "feeling of burden when not applied to the skin", "effect of uniformly hiding spots and uneven skin color", and "effect of maintaining makeup". Comparative examples 6 and 7 containing no component (B) were inferior in "effect of uniformly hiding spots and uneven skin color", "natural makeup", "effect of maintaining makeup". This is presumably because the component (B) present in the furrows has poor sebum absorbing ability, and thus the cosmetic film does not last due to long-term sebum secretion. In comparative example 9 containing particles larger than component (C), "feeling of burden on the skin when not applied" was inferior. Comparative example 8, which did not contain component (C) and increased the amount of component (a), exhibited a high "uv-blocking effect", but poor "feeling of burden on the skin when not applied" and "cosmetic persistence effect".
