Description

Technical Field

[0001] The present invention relates to a composite powder having no luster, in which titanium oxide is coated in layers on the surface of mica and further coated with iron oxide, a spherical powder having a specific size, and a powder-containing cosmetic containing titanium oxide having a specific coated particle diameter. More specifically, when it spreads on the skin, it has no sense of burden, especially it naturally and uniformly hides freckles and color unevenness, and further, even after a lapse of time, it does not feel dryness and maintains a uniform finish, and also has a high blocking ability in the ultraviolet region. It relates to a powder-containing cosmetic.

Background Art

[0002] Conventionally, in powder-containing cosmetics, various concealer powders have been developed and studied for formulation in order to naturally and uniformly hide freckles such as liver spots and senile pigmented spots, which are high consumer concerns, and color unevenness such as acne marks. In particular, titanium oxide has a high refractive index and is excellent in whiteness and coloring power, so it is widely used as a concealer powder and is also widely used for the purpose of imparting an ultraviolet protection effect. On the other hand, iron oxide is widely used as a coloring pigment for color adjustment to match each person's skin color. For example, for the purpose of having an ultraviolet protection effect and excellent moldability, a plate-shaped powder having an aspect ratio of 10 or more and having no luster, which is formed by coating two or more of these on the surface of mica, is used to naturally hide freckles and color unevenness while protecting the skin from ultraviolet rays. A solid powder cosmetic has been developed (see, for example, Patent Document 1). Furthermore, a powder cosmetic excellent in ultraviolet protection effect and usability has been developed by combining a plate-shaped powder coated with a fine particle inorganic powder having a high ultraviolet protection effect and a spherical powder also coated with a fine particle inorganic powder (see, for example, Patent Document 2). In addition, in a cosmetic using a composite powder in which a metal oxide having a limited particle diameter is coated on a plate-shaped powder, a solid powder cosmetic having a finish with no crunchiness, no powdery feeling, and no dullness after application has been developed (see, for example, Patent Document 3). On the one hand, for the purpose of imparting a natural finish and concealment, a powder in which iron oxide is coated on the surface of titanium oxide having a specific particle size has been developed, and a cosmetic containing a finish film having concealment power without becoming unnaturally white and having little color fading due to wetting over time has been developed (see, for example, Patent Document 4). Furthermore, as powders for making unevenness on the skin such as pores and wrinkles less noticeable, spherical powders with various particle sizes and compositions have been developed, and spherical cellulose powders that impart a soft focus effect by diffuse reflection of visible light have been developed, and cosmetics with no sticky feeling, a smooth touch, and excellent long-term stability have been developed (see, for example, Patent Document 5).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the prior art of Patent Document 1 above, as a method of coating titanium oxide on plate-shaped mica, a method of mixing titanium oxide and mica using a bead mill or the like and fixing them has been carried out. However, titanium oxide is not uniformly coated on the mica surface, and there may be cases where the ultraviolet blocking ability and the feel without a burden are inferior, and there is room for further improvement in the coating method and the composition constituting the composite powder. Furthermore, in Patent Documents 2 and 3, the fine particle inorganic powder coated on the plate-shaped powder has a specific particle shape, and compared with the layered coating, the surface smoothness is inferior, so the spreading is poor, the oil absorption amount is high, a dry feeling is felt, and it may be difficult to be arranged uniformly on the skin surface. The development of a plate-shaped powder in which a metal oxide is coated in layers without having glow while maximizing the ultraviolet blocking ability, arranging smoothly on the skin, and not feeling a dry feeling has been desired. On the other hand, when using the prior art of Patent Document 4 above and a higher ultraviolet blocking ability is required for a powder-containing cosmetic for iron oxide-coated titanium oxide that naturally conceals spots and color unevenness, it may be inferior when blended alone. Therefore, in some cases, the function may be improved by combining with fine particle metal oxides. However, due to the spreading with a sense of burden and an unnatural finish, a powder-containing cosmetic that achieves both a natural finish and a high ultraviolet blocking ability has been desired. Also, in the prior art of Patent Document 5 above, while correcting pores and unevenness, sebum secreted over time is absorbed to maintain a uniform finish. However, when these powders are combined with other powders having good spreading, they tend to selectively exist in the concave portions of the skin, and there has been no intensive study on efficiently absorbing sebum in pores and reducing the dry feeling on the convex portions. Thus, in the conventional technology, there has been no idea of controlling each surface shape to promote the appropriate arrangement of the powder on the skin while exhibiting various effects.

Means for Solving the Problems

[0005] As a result of intensive research to solve the above problems, the present inventors have found that by combining a non-glossy composite powder obtained by laminarly coating titanium oxide on the surface of mica and further coating iron oxide, spherical powder having a specific size, and titanium oxide having a specific particle diameter and surface coating, it has a natural finish while spreading smoothly without a sense of burden, provides a uniform concealing effect against stains and color unevenness, has a long-lasting makeup effect without a dry feeling over time, and has excellent ultraviolet blocking effect, thus completing the invention.

[0006] That is, the present invention is a powder-containing cosmetic characterized by containing the following components (A) to (C), and further (D) based on the technical idea of orienting spherical powder having a specific particle diameter in skin grooves while orienting iron oxide and titanium oxide-coated plate-like mica in skin mounds. 〔1〕 The following components (A) to (C); (A) A plate-like composite powder having no gloss, which is a composite powder obtained by laminarly coating 30 to 50% by mass of titanium oxide on the surface of mica and further coating 0.1 to 3.0% by mass of iron oxide (B) Spherical powder having an average particle diameter of 1 to 40 μm (C) Titanium oxide and / or zinc oxide having an average particle diameter of 0.1 to 1.2 μm, which is coated with one or more selected from oxides or hydroxides of iron, aluminum, and silicon A powder-containing cosmetic containing 〔2〕 The powder-containing cosmetic according to the above [1], wherein the titanium oxide of the component (A) does not take a particle shape on the surface of mica and the average thickness of the titanium oxide layer is 50 to 100 nm. 〔3〕 The powder-containing cosmetic according to the above [1] or [2], wherein the component (A) is further coated with a hydrophobizing agent. 〔4〕 The powder-containing cosmetic according to any one of claims 1 to 3, wherein the component (A) is further coated with 0.1 to 4% by mass of zinc oxide. 〔5〕 The powder-containing cosmetic according to any one of [1] to [4] above, wherein the component (C) is titanium oxide coated with one or more oxides or hydroxides selected from iron and oxides or hydroxides selected from aluminum and silicon.

[8] Furthermore, it is the powder-containing cosmetic according to any one of [1] to [7] above, which contains 2 to 40% by mass of a powder surface-treated with a component (D) crosslinked silicone.

Modes for Carrying Out the Invention

[0010] Preferred embodiments of the present invention will be described in detail. However, the present invention is not limited to the following preferred embodiments and can be freely changed within the scope of the present invention. In the present specification, percentages are by mass unless otherwise specified. In the present specification, when representing a numerical range using ~, the range includes the numerical values at both ends. Further, the "average particle diameter" in the present invention is a value (median diameter D50) obtained by observing the surface state using a scanning electron microscope (JSM-7800prime, manufactured by JEOL Ltd.) and measuring it with an image analyzer (Luzex AP, manufactured by Nireco Corporation), and refers to the major axis of the particles.

[0011] Component (A) used in the present invention is a plate-like composite powder having no luster, and a composite powder in which 30 to 50% by mass of titanium oxide is coated in layers on the surface of mica and further 0.1 to 3% by mass of iron oxide is coated has a uniform finish, can last for a long time without feeling a sense of dryness, and has a high ultraviolet blocking effect. The mica serving as the mother powder of the plate-shaped composite powder of component (A) of the present invention has a plate shape, and examples include natural mica such as phlogopite, muscovite, and especially sericite, synthetic phlogopite, and synthetic mica such as (fluoride / hydroxide / oxide) / (Mg / K / silicon). The aspect ratio is preferably 10 to 50, more preferably 10 to 30. When the aspect ratio is small, the amount of titanium oxide to be coated decreases, resulting in inferior ultraviolet blocking effect and reduced orientation on the dermal papilla, and the cosmetic film may be inferior in uniformity. Also, when the aspect ratio is large, the bulk specific gravity increases, which may limit the blending amount in the powder-containing cosmetic. Among these, those with high whiteness are preferred. Sericite, which is less likely to have a glittery appearance when composited in layers, and synthetic phlogopite, which has little color change when wetted with an oil agent and can control the surface treatment during coating to control the glittery appearance and the adhesion of metal oxides, are preferred. In particular, sericite, which is available at a low cost, is more preferred.

[0012] As a method for coating mica with titanium oxide or the like of component (A) of the present invention, unlike the method of spraying and adsorbing a solvent in which titanium oxide or iron oxide prepared in advance is mechanically chemically fixed (adsorbed) or dispersed on the surface using mechanical force such as a bead mill, a Henschel mixer, or a pulverizer (hereinafter collectively referred to as the adsorption method), it is a method of densely depositing and growing titanium oxide on the mica surface (hereinafter referred to as the precipitation method). For example, mica is suspended in a dilute strongly acidic solution of titanyl sulfate at ambient temperature, rapidly heated to 90 to 100 °C, and the titanyl sulfate solution is hydrolyzed while maintaining this temperature for about 2 to 3 hours, so that a hydrous oxide layer is deposited on the substrate. Another example is a method in which the substrate is suspended in hot water, a strongly acidic concentrated titanyl sulfate solution is rapidly added, and the hot water is continuously heated until the hydrolysis is complete to cause hydrolysis and deposition of hydrous titanium oxide on the mica. By these precipitation methods, it is possible to coat the entire surface of the plate-shaped mica with titanium oxide having ultraviolet blocking ability in layers. Therefore, compared with the conventional adsorption method, a composite powder with a feeling of no burden can be obtained without aggregation of titanium oxide.

[0013] The amount of titanium oxide in component (A) of the present invention is preferably 30 to 50%. When the blending amount is small, the ultraviolet blocking effect is poor. When the blending amount exceeds 50%, it becomes an excessive amount with respect to the mica surface, making it difficult to uniformly form a layer and unable to be compounded, and it may precipitate as particles alone. In that case, the feel of spreading is inferior, the composite powders aggregate with each other, and the ultraviolet blocking ability cannot be effectively obtained. Furthermore, it becomes difficult to arrange smoothly on the skin, and a uniform concealing effect cannot be expected, and a dry feeling may be felt. The layered coating means that the titanium oxide on the mica surface does not take a particle shape on the mica surface. The thickness of the titanium oxide layer is preferably 50 to 100 nm, and it is preferably smooth with few irregularities, but the thickness is not particularly limited. Within this thickness range, the covering power is difficult to appear, the ultraviolet blocking effect is efficiently high, and particularly in the case of papules, it is easy to realize a uniform spread, there are few irregularities and it is difficult for the oil absorption amount to increase, so it is possible to reduce the dry feeling in papules that are prone to feeling dry.

[0014] Furthermore, as a method of further coating the mica coated with titanium oxide of component (A) of the present invention with iron oxide, it is not particularly limited, such as a dry method or a wet method. For example, after uniformly dispersing the slurry of the coating pigment in an aqueous solution of a water-soluble iron salt (ferrous chloride, ferric chloride, ferrous sulfate, ferric sulfate, ferrous nitrate, ferric nitrate, etc.), an aqueous solution of sodium acetate is gradually added under stirring to adjust the pH to 3 to 5, and the mixture is heated to a temperature of 60°C or higher to hydrolyze the iron salt, so that amorphous hydrated oxide is selectively precipitated and deposited on the particle surface of the coating pigment. When the appearance color changes, an aqueous solution of an alkali is added and the pH of the system is adjusted to 8 to 9.5 while heating. Then, an iron oxide-coated titanium oxide-coated mica can be obtained by methods such as filtration, washing with water, drying, or firing and pulverization.

[0015] The amount of iron oxide in component (A) of the present invention is not particularly limited. However, as a lower limit, 0.1% or more is preferable, 1.0% or more is more preferable, and 1.5% is even more preferable. As an upper limit, 5% or less is preferable, 3% is more preferable, and 2.5% is even more preferable. When it is within this range, the blueness of the composite powder itself can be reduced, and a more natural color tone that is more compatible with the skin can be obtained. In addition, the amount of iron oxide separately blended in the powder-containing cosmetic can be reduced, the aggregability of iron oxide can be reduced, and the ultraviolet ray blocking effect, particularly in the UVA region, can be improved. Furthermore, when it is coated with 0.1 to 4% by mass of zinc oxide, the ultraviolet ray blocking effect is further enhanced, the antiseptic power is also improved, and it may react with the surface treatment agent to easily form metal soap, and more preferable effects can be further imparted. When it is within this coating range, it is more preferable because the uniform spreading is not hindered by the aggregating power of zinc oxide.

[0016] 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 obtained by measuring with ICP (Inductively Coupled Plasma; inductively coupled plasma; ARCOS (manufactured by Spectro Analytical Instruments GmbH)) emission analysis of a sample prepared using a general method.

[0017] Component (A) of the present invention does not have luster, but the presence or absence of luster is defined by measurement by, for example, the following measurement method. That is, a 40 mm wide double-sided tape manufactured by Nichiban Co., Ltd. is attached to the black part of OPACITY CHARTS manufactured by LENETA Co., Ltd., and the composite powder is uniformly applied with a cosmetic puff. The applied sample is fixed at an incident angle of 45 degrees with a digital variable angle gloss meter manufactured by Suga Test Instruments Co., Ltd., and the gloss intensity (I20) at a light receiving angle of 20 degrees and the gloss intensity (I45) at 45 degrees are measured, I45 / I20 is calculated, and from this ratio, I45 / I25 = 2.0 or more: having luster I45 / I25 < 2.0: having no luster is defined as follows.

[0018] The UV transmittance of the composite powder of component (A) of the present invention was evaluated under the following conditions. First, 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 under the conditions of a dispersing rotation speed of 3000 rpm for 10 minutes. Next, using a doctor blade (with a thickness of 12 μm), a coating film was prepared on a quartz plate so that the thickness was the same, and the transmittance of the coating film in the wavelength range of 250 to 700 nm was measured with a spectrophotometer (U-4100 manufactured by HITACHI). For the evaluation of the blocking ability in the UVA region of 320 to 400 nm, the transmittance at 360 nm was used, and for the evaluation of the blocking ability in the UVB region of 280 to 320 nm, the transmittance at 300 nm was used. It is preferable that the transmittance is less than 50% respectively, and more preferably less than 25%.

[0019] Furthermore, the average particle diameter of component (A) of the present invention is not particularly limited. As the lower limit, it is preferably 3 μm or more, and as the upper limit, it is preferably 30 μm or less, and more preferably 20 μm or less. In particular, those with a uniform particle size distribution are more likely to form a uniform cosmetic film, which is even more preferable.

[0020] Furthermore, component (A) of the present invention preferably has a low oil absorption amount. The oil absorption amount of the present invention is defined as the oil absorption amount with respect to triethylhexanoin, which is a triglyceride similar to sebum. The measurement method follows the method of JIS K5105. For 100 g of spherical powder, instead of linseed oil, triethylhexanoin, which is one of the sebum components, is gradually added until it becomes a slurry state as the end point. Specifically, although not particularly limited, it is preferably 100 ml / 100 g or less, and more preferably 70 ml / 100 g or less. Since component (A) of the present invention is plate-shaped, it is likely to adhere to the smooth convex parts of the skin. However, since the matrix mica is thin and a metal oxide is compounded on the surface, it tends to have a high oil absorption amount per unit weight. If the oil absorption amount is too high, it is likely to feel a dry feeling by removing the sebum on the skin surface, and it may be necessary to appropriately adjust the blending amount and surface treatment amount in the cosmetic.

[0021] Therefore, by subjecting component (A) of the present invention to a hydrophobic surface treatment, a smooth spreading property and a drying feeling can be reduced, and the makeup durability can be further improved. The hydrophobic treatment agent is not particularly limited, and the details will be described later in summary.

[0022] The blending amount of component (A) used in the powder-containing cosmetic of the present invention is preferably 1% or more, more preferably 3% or more, and still more preferably 5% or more as the lower limit. As the upper limit, it is preferably 50% or less, more preferably 30% or less, and still more preferably 15% or less. Within this range, particularly good results can be obtained in terms of the expression of the ultraviolet blocking effect, a natural finish, and the absence of a drying feeling.

[0023] The spherical powder of component (B) used in the present invention has an average particle diameter of 1 to 40 μm. The spherical shape means that the ratio of the major axis to the minor axis: major axis / minor axis is 1 to 1.5, and even if there are fine irregularities on the surface or the interior is hollow, it does not matter. As the lower limit, the average particle diameter is preferably 1 μm or more, more preferably 3 μm or more, and as the upper limit, it is preferably 40 μm or less, more preferably 30 μm or less. When the average particle diameter is smaller than 1 μm, the aggregability increases in the skin grooves, and the effect of hiding irregularities such as pores and wrinkles is inferior. When it exceeds 40 μm, the spreading property is poor, scattering occurs, and the makeup durability deteriorates, which is not preferable. The material is not particularly limited, and examples include organic powders such as nylon powder, polystyrene powder, polyethylene powder, polymethyl methacrylate resin powder, silicone resin powder, polyurethane powder, cellulose powder, cellulose acetate powder, silk powder, starch, calcium polyalgalate, silicone, and urethane, and inorganic powders such as silica and calcium carbonate. Due to the background of the environmental problems of microplastic beads in recent years, in particular, the blending of spherical cellulose, silica, calcium carbonate, and starch is more preferable.

[0024] Furthermore, a metal oxide may be complexed on the surface of component (B). Preferably, particles with a size of 10 to 1200 nm may be deposited or adsorbed on the surface, or may be encapsulated inside component (B). The metal oxide is not particularly limited, but titanium oxide, zinc oxide, aluminum oxide, and cerium oxide are preferably mentioned. Component (C) may be complexed with component (B) in advance.

[0025] The blending amount of component (B) of the present invention is not particularly limited. As the lower limit, 0.5% or more is preferable, 2% or more is more preferable, and 5% or more is even more preferable. As the upper limit, 30% or less is preferable, 25% or less is more preferable, and 20% or less is even more preferable. Within this range, it can penetrate into the concave parts of the skin, make the unevenness less noticeable, adsorb sebum, and maintain a uniform makeup film.

[0026] The oil absorption of the spherical powder of component (B) is not particularly limited, but the oil absorption with respect to triethylhexanoin, which is a triglyceride similar to sebum, is preferably 60 ml / 100 g or more, more preferably 70 ml / 100 g or more as the lower limit, and preferably 350 ml / 100 g or less, more preferably 200 ml / 100 g or less as the upper limit. When it is within this range, the sebum absorption of the spherical powder oriented near the pores in the skin grooves is appropriate, the makeup durability is excellent, and it does not absorb sebum more than necessary, so there is no feeling of dryness. A porous powder is preferred. However, it is possible to adjust the dryness by pre-absorbing oil, and it may also be adjusted with a surface treatment agent or the like. For example, in the case of silicone resin powder, KSP-100 (oil absorption: 80 ml / 100 g) (manufactured by Shin-Etsu Chemical Co., Ltd.), in the case of polyurethane powder, for example, Plastic Powder CS-400 (oil absorption: 90 ml / 100 g) (manufactured by Negami Kogyo Co., Ltd.), in the case of silica, for example, God Ball D11-796C (oil absorption 83-89 ml / 100 g), God Ball E-90C (110-140 ml / 100 g) (manufactured by Suzuki Oil & Fat Co., Ltd.), in the case of crosslinked polymethyl methacrylate, for example, MBP-8 (oil absorption 140 ml / 100 g) (manufactured by Sekisui Chemical Co., Ltd.), in the case of spherical cellulose, for example, CELLULOBEADS D-10 (oil absorption: 150 ml / 100 g) (manufactured by Tohto Kasei Co., Ltd.), etc. can be mentioned.

[0027] The coated titanium oxide and / or zinc oxide of component (C) is titanium oxide and / or zinc oxide coated with one or two selected from silicon oxides or hydroxides, aluminum oxides or hydroxides, and iron oxides or hydroxides. The particles of titanium oxide and / or zinc oxide, which are the mother nuclei of the coated titanium oxide and / or zinc oxide of the present invention, are not particularly limited in shape, but are titanium oxide alone, or those containing zinc oxide in titanium oxide, or zinc oxide alone (hereinafter referred to as the mother nucleus).

[0028] In the coated titanium oxide and / or zinc oxide of component (C), the titanium oxide which is the mother nucleus before coating can be obtained by using a known method for producing titanium oxide powder, and it is also possible to use a commercially available product as the mother nucleus. Further, although there are anatase type and rutile type crystal forms in the titanium oxide serving as the mother nucleus, the rutile type which has low photocatalytic activity and high refractive index and thus high hiding power is preferred. Alternatively, it is preferable to incorporate a small amount of zinc oxide into the titanium oxide powder serving as the mother nucleus for stabilizing the crystal shape. The zinc oxide content in the titanium oxide serving as the mother nucleus is preferably 1% by mass or less, more preferably 0.1 - 0.8% by mass, and still more preferably 0.2 - 0.7% by mass in terms of oxide mass conversion. Alternatively, zinc oxide which is the mother nucleus can be used alone. This zinc oxide can be obtained by using a known method for producing zinc oxide.

[0029] The shape of the titanium oxide and / or zinc oxide serving as the mother nucleus of component (C) is not particularly limited, and examples include straw bundle shape, strip shape, spherical shape, needle shape, rod shape, plate shape, etc. Among these, the titanium oxide and / or zinc oxide used as the mother nucleus of the present invention is preferably spherical or plate-shaped with a relatively smooth surface.

[0030] The coated titanium oxide and / or zinc oxide of component (C) is preferably coated with the surface treatment amount of each metal within the following specific ranges. By setting it within this range, a more natural three-dimensional effect of the skin can be obtained more favorably, and furthermore, the blueness and sallowness of the skin can be reduced more, resulting in a natural and uniform hiding effect. In the coated titanium oxide and / or zinc oxide of component (C), the surface treatment amount of aluminum is preferably 1 - 6%, more preferably 1 - 5%, and still more preferably 2 - 5% in terms of oxide mass conversion. The surface treatment amount of silicon is preferably 0.5 - 6%, more preferably 1 - 6%, and still more preferably 3 - 6% in terms of oxide mass conversion. The surface treatment amount of iron is preferably 0.5 - 3%, more preferably 0.5 - 2%, and still more preferably 0.5 - 1.5% in terms of oxide mass conversion.

[0031] In the powder-containing cosmetic of the present invention, the content of component (C) preferably has a lower limit of 0.5% or more, more preferably 3% or more, and still more preferably 5% or more. Further, as the upper limit, 30% or less is preferable, 20% or less is more preferable, and 15% or less is still more preferable.

[0032] Component (C) is preferably one coated with silicon oxide or hydroxide on the surface of the mother nucleus, because its dispersibility is improved and uniform hiding power is imparted. Further, those coated with aluminum oxide or hydroxide, or iron oxide or hydroxide are more preferable. Furthermore, those having three kinds of these layers (hereinafter, each of these layers is also referred to as "silicon coating layer", "aluminum coating layer", and "iron coating layer") are still more preferable. Those in which the surface of the particles in which the silicon coating layer and the aluminum coating layer are mixed is coated with iron oxide or hydroxide are even more preferable. By having a plurality of coating layers mixed on the surface in this way, a natural finish can be achieved, the spreading is good, and uniform hiding power can be realized. That is, by controlling the coating layer, the surface charge changes, and adsorption points for various surface treatment agents can be created, resulting in good dispersibility in the powder-containing cosmetic. As a result, component (C) is uniformly dispersed regardless of the unevenness of the skin, adheres to and disperses on the surface of component (A) or (B) appropriately without hindering the spreading of component (A) and (B), and can bring about a synergistic effect of uniform hiding power. In particular, the presence of an iron coating layer increases the ease of blending with the skin color, has a natural finishing effect while having hiding power, and makes it difficult for the makeup film to break, so it is preferable because the makeup persistence effect is enhanced.

[0033] The method for coating the component (C) with the oxide or hydroxide of silicon is not particularly limited and can be carried out using a known coating method. For example, sodium silicate or the like is added as it is or in an aqueous solution to a water slurry containing raw material particles, and then an acid such as sulfuric acid is added to precipitate silica or its hydrate; or the raw material particles are dispersed in a solvent (such as alcohol, water, or an alcohol-water mixed solvent), an alkoxysilane-based metal coupling agent such as tetraethoxysilane is added, and an acid or base is added or heating is carried out, etc. to precipitate silica or its hydroxide. Thereafter, the coated powder particles can be obtained by performing washing, filtration, drying, etc.

[0034] The method for coating the component (C) with the oxide or hydroxide of aluminum is not particularly limited and can be carried out using a known coating method. For example, aluminum nitrate, aluminum sulfate, sodium aluminate, etc. are added as it is or in an aqueous solution to a water slurry containing raw material particles, and then an acid or alkali is added to precipitate an aluminum compound. Also, the raw material particles are dispersed in a solvent (such as alcohol, water, or an alcohol-water mixed solvent), an aluminum-based metal coupling agent is added, and an acid or base is added or heating is carried out, etc. to precipitate aluminum or its hydroxide. Thereafter, the coated powder particles can be obtained by performing washing, filtration, drying, etc.

[0035] The method for coating the component (C) with the iron oxide or hydroxide is not particularly limited, and it can be carried out by using a known iron oxide coating treatment method. For example, as an example, an aqueous sodium hydroxide solution is heated to 30 to 35 °C, powder particles are dispersed, an aqueous solution containing ferric sulfate is added and stirred, and the reaction is carried out at 90 °C for about 2 hours. The obtained composite compound is washed with water, neutralized, and dried. After pulverization, it can be obtained by firing the raw material particles and the iron oxide or hydroxide (for example, at about 750 to 900 °C for about 1 to 3 hours). Examples of the iron compound include ferric oxide, ferrous oxide, magnetite, iron hydroxide, iron organic acid (such as iron oxalate, iron citrate, etc.), iron inorganic acid (such as iron chloride, ferric sulfate, iron sulfate, etc.), and one or more of these groups can be selected. The iron compound exists as iron oxide or iron hydroxide in the particles.

[0036] In the coated titanium oxide and / or zinc oxide of the component (C), the average particle diameter D50 by 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 as the lower limit value. As the upper limit value, it is preferably 1.20 μm or less, more preferably 1.00 μm or less, still more preferably 0.8 μm or less, and even more preferably 0.50 μm or less. By adopting such a particle diameter, it is easy to spread on the skin, has a natural finish, and can obtain uniform hiding power and makeup persistence.

[0037] In addition, the component (A), component (B), and component (C) of the present invention can be further surface-treated as long as the effects of the present invention are not impaired. By performing surface treatment, it is possible to impart makeup retention and usability associated with viscosity, dispersibility in oil, water repellency, etc. This surface treatment can be carried out using known surface treatment methods for powders. As surface treatments such as water repellency and / or oil repellency, for example, silicone compounds (e.g., dimethylpolysiloxane, methylhydrogenpolysiloxane, etc.), coupling agents (e.g., silane-based such as alkylalkoxysilane treatment, aluminum-based, titanium-based, etc.), fluorine compounds (e.g., perfluoroalkylalkoxysilane treatment), hydrocarbons, lecithin·hydrogenated lecithin, amino acids·peptides, amino acid derivatives (e.g., as N-acyl amino acid treatment, lauroyl lysine treatment, dilauroyl glutamate lysine Na treatment, stearoyl glutamate 2Na treatment, lauroyl aspartic acid Na treatment), polyethylene, wax, fatty acids (e.g., stearic acid, palmitic acid, myristic acid)·fatty acid salts·fatty acid esters·fatty acid amides, metal soaps, etc. can be used for treatment.

[0038] In the present invention, it is preferable to further contain, as component (D), a powder treated with dimethiconol and aminopropyltriethoxysilane. Component (D) is a both-terminal reactive diorganopolysiloxane represented by the following general formula (1) R 1 R 2 2SiO-(R 2 2SiO) L -SiR 1 R 2 2(1) (In the formula, each R 1 represents a hydroxyl group, each R 2 independently represents a hydrocarbon group having 1 to 20 carbon atoms, and L represents an integer of any one of 3 to 10,000) and an amino group-containing silane compound represented by the following general formula (2) R 3 R 4 m SiX (3-m) (2) (In the formula, R 3represents a hydrocarbon group having 1 to 20 carbon atoms and at least one amino group, R 4 represents an alkyl group having 1 to 4 carbon atoms, X each independently represents an alkoxy group having 1 to 4 carbon atoms, and m is 0 or 1) may contain a powder coated with . As a preferred embodiment of component (D), it is a powder whose surface is coated with a polymer having a micro three-dimensional cross-linked structure of silicone (hereinafter referred to as "silicone micro cross-linked product") obtained by subjecting (1) and (2) of the above surface coating treatment agent to a condensation reaction. The silicone micro cross-linked product may be a compound having no rubber elasticity, and the mass ratio of (a) to (b) can be obtained in the range of approximately 100:0.1 to 100:35. When (b) is less than 0.1% by mass, it is a viscous silicone oil or gum-like, and when it is more than 35% by mass, it becomes a silicone elastomer having elasticity, and the water repellency of the powder with the surface coating tends to decrease.

[0039] Further, as component (D), it is preferable to contain a polymer having a dimethicone structure having a three-dimensional cross-linked structure in part obtained by cross-linking an organopolysiloxane. The polymer having a dimethicone structure having a three-dimensional cross-linked structure is not particularly limited, but those having a structure cross-linked with divinyldimethylpolysiloxane or those having a structure cross-linked with an alkyl group having 3 to 20 carbon atoms are preferable. In addition, its shape is not particularly limited as long as it can coat the powder surface. For example, (dimethicone / vinyl dimethicone) cross-polymer cross-linked with divinyldimethylpolysiloxane and dimethicone cross-polymer having an alkyl group in the cross-linked part can be mentioned. Further, a polymer containing a polyoxyalkylene group in the molecule or a polymer containing a polyoxyalkylene group and a long-chain alkyl group in the molecule is not particularly limited.

[0040] The blending amount of component (D) is preferably 1 to 50% in the powder-containing cosmetic, and more preferably 2 to 40%. Within this range, particularly good results can be obtained in terms of the manifestation of effects and finish. Incidentally, components (A), (B), and (C) may be surface-treated with component (D) as a surface treatment agent.

[0041] Furthermore, as component (E) the preservative, dipropylene glycol, 1,2-alkanediol, ethylhexyl glycerin, and chlorphenesin may be blended. In the powder-containing cosmetic of the present invention, when component (E) is used in combination, components (A) to (C) can bring about an antiseptic effect without being hindered from spreading.

[0042] The blending amount of component (E) is preferably 0.001 to 0.5% in the powder-containing cosmetic, and more preferably 0.01 to 0.3%. Within this range, it is possible to ensure the antiseptic property of the powder-containing cosmetic, without hindering usability, while maintaining makeup persistence and further ensuring safety to the skin, a powder-containing cosmetic can be provided. In particular, in providing a powder-containing cosmetic without using parabens, it further exerts an effect.

[0043] The powder-containing cosmetic of the present invention can contain other optional components within a range that does not impair the effects of the present invention according to the purpose. For example, oily components, pigments, pH adjusters, moisturizers, thickeners, surfactants, dispersants, stabilizers, colorants, preservatives, antioxidants, sequestering agents, astringents, anti-inflammatory agents, ultraviolet absorbers, fragrances, and other pigments and the like can be mentioned.

[0044] The powder-containing cosmetic of the present invention is not particularly limited as long as it is a dosage form containing a large amount of powder or a dosage form requiring ultraviolet blocking ability. Preferably, powders, powder solids, oily, oily solids, emulsions, and emulsion solids can be mentioned. As uses in the powdery cosmetic of the present invention, for example, it can be used in makeup cosmetics (such as white powder, base makeup, foundation, concealer, face powder, control color, sunscreen cosmetics, eyeshadow, eyeliner, mascara, cheek color, body powder, perfume powder, baby powder, etc.), body cosmetics, etc. Among these, since a natural three-dimensional effect can be obtained by using the present invention, white powder, base makeup, foundation, concealer, face powder, control color, sunscreen cosmetics, body powder, etc. are preferable, and powdery cosmetics that can be used on the face are more preferable.

Examples

[0045] The present technology will be described in more detail below by way of examples and comparative examples, etc. Note that these do not limit the present invention in any way. Table 1 shows the evaluation method and evaluation results as the material of component (A).

[0047] Production Examples 1 to 9: Produced by precipitation method A. The aspect ratio of the matrix is 20 to 30 for Production Examples 1 to 3, 5 to 8, 10 to 20 for Production Example 4, and 68 for Production Example 9. The oil absorption amount is 65 ml / 100 g for Production Example 4 and 63 ml / 100 g for Production Example 5. Production Comparative Example 1: Produced by adsorption method B (mixed at 3000 rpm with a high-speed Henschel mixer and pulverized with a parubellizer). MT-500B (manufactured by Teika Co., Ltd.), MZ-300 (manufactured by Teika Co., Ltd.), Sanshin Serisaito FSE (manufactured by Sanshin Kogyo Co., Ltd.), and 3% isostearic acid were mixed. Production Comparative Example 2: Produced by the same adsorption method B as in Production Comparative Example 1. MT-150EX (manufactured by Teika Co., Ltd.) with an average particle diameter of 15 nm and a titanium oxide content of 40%, 1% of TRY-100HP, 0.5% of TRR-100HP (manufactured by Titanium Industry Co., Ltd.), and Serisaito LQ-15 (traded by Okem Co., Ltd.) were mixed. The oil absorption amount is 80 ml / 100 g. Manufacturing Comparative Example 3: Cover Leaf PC-2035M (manufactured by Shokubai Kasei Kogyo Co., Ltd.)

Manufacturing Comparative Example 5: Blondii Metallic Gold N-2000S (manufactured by CQV Co., Ltd.)

[0048] The iron oxide-titanium oxide-coated plate-like mica prepared by the precipitation method of component (A) of the present invention (Manufacturing Example 5 ) was observed using a scanning electron microscope (JSM-7800prime manufactured by JEOL Ltd.) at an acceleration voltage of 5 kV and a magnification range of 5000 to 100000 times. The photograph of the surface state is shown in Fig. 1. As a detailed explanation of Fig. 1, a portion where the titanium oxide layer deposited on the mica surface of the matrix was partially peeled off was made, and the thickness of the titanium oxide layer was confirmed at 20 locations. As a result, it was 50 to 100 nm. In addition, as a result of performing elemental mapping on the composite powder of component (A) at an acceleration voltage of 10 kV using energy-dispersive X-ray analysis (X-MAX manufactured by Oxford), it was found that Ti elements were uniformly present throughout. Furthermore, since the powder scattered on the surface was Fe element, the scattered powder was identified as iron oxide.

[0049] On the other hand, zinc oxide-titanium oxide-coated mica prepared by the mechanochemical method (Manufacturing Comparative Example 1) is shown in Fig. 2. As a detailed explanation of Fig. 2, it can be seen that zinc oxide and titanium oxide are fixed to the mica surface of the matrix in a particulate form with irregularities. At the same time, as a result of performing elemental mapping using energy-dispersive X-ray analysis (EDX), since Ti elements and Zn elements are present unevenly, it was found that titanium oxide and zinc oxide are fixed to the surface unevenly.

[0050] [Evaluation method: UVB transmittance (300 nm), UVA transmittance (360 nm)] The ultraviolet blocking ability of the composite powder of component (A) of the present invention was evaluated under the following conditions. First, 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 under the conditions of a dispersing rotation speed of 3000 rpm for 10 minutes. Next, using a doctor blade (thickness of 12 μm), a coating film was prepared on a quartz plate so that the thickness was the same, and the transmittance of the coating film in the wavelength range of 250 to 700 nm was measured with a spectrophotometer (U-4100 manufactured by HITACHI). For the evaluation of the blocking ability in the UVA region of 320 to 400 nm, the transmittance at 360 nm was used, and for the evaluation of the blocking ability in the UVB region of 280 to 320 nm, the transmittance at 300 nm was used, and the evaluation was carried out taking into account that it blocks in a wide range from UVB to UVA. Table 1 shows each composite powder, its transmittance, and the evaluation results of the blocking ability. The evaluation level was evaluated according to the following levels.

[0051] 〔Evaluation criteria〕: ◎: The transmittance is less than 25%. (◎*: The transmittance is less than 20%) ○: The transmittance is 25% or more and less than 50% △: The transmittance is 50% or more and less than 75% ×: The transmittance is 75% or more and less than 100%

[0052] From Table 1, it was found that the composite powders of component (A) prepared using the precipitation method (Production Method A) of Production Examples 1 to 9 blocked in a wide range from UVB to UVA. As shown in Figure 1, it is presumed that the mica surface is uniformly and densely coated with a titanium oxide layer and further coated with iron oxide. On the other hand, the zinc oxide-titanium oxide-coated plate-like mica and titanium oxide-coated mica prepared by the adsorption method (Production Method B) of Production Comparative Examples 1 and 2 had poor blocking ability from UVB to UVA because titanium oxide and zinc oxide were not firmly fixed on the mica surface. In addition, Production Comparative Examples 3 and 4 prepared using the precipitation method (Production Method A) had titanium oxide present in a particulate state, and together with the shiny iron oxide-titanium oxide-coated plate-like mica of Production Comparative Example 5, they had poor blocking ability from UVB to UVA.

[0053] [Evaluation method: Uniform spreading, lack of covering power] Furthermore, regarding the uniform spreading and lack of covering power of each powder, 20 professional panels for cosmetic evaluation were asked to evaluate it in five grades according to the following criteria respectively. For each composite powder, it was spread on a certain area of skin to give a score, and the average score of all panels was judged according to the following judgment criteria. 〔Evaluation criteria〕: (Evaluation result): (Score) Very good: 5 points Good: 4 points Average: 3 points Slightly poor: 2 points Poor: 1 point 〔Judgment criteria〕: (Average score): (Judgment) 4.0 or more: ◎ 3.0 or more and less than 4.0: ○ 1.5 or more and less than 3.0: △ Less than 1.5: ×

[0054] From Table 1, the composite powders of Production Examples 1 to 9 are excellent in uniform spreading and lack of covering power. On the other hand, in Production Comparative Examples 1 and 2, titanium oxide and zinc oxide are fixed in a particulate state on the mica surface, so there are large irregularities, and a uniform spread cannot be obtained with a feeling of squeak and powdery touch. Some of the particles also aggregated, making it easy to obtain covering power. In Production Comparative Examples 3, 4, and 5, although there is still a uniform spread, the ultraviolet blocking ability is low. In Production Comparative Example 5, due to its luster, it is particularly easy to obtain covering power.

[0055] Powder foundations with the compositions shown in Tables 2 and 3 were prepared according to the following production methods. Regarding the obtained powder foundations, the following evaluation methods were used to evaluate the "lack of burden when spreading on the skin", "effect of uniformly concealing spots and color unevenness", "natural finish", "lack of dryness over time", "cosmetic lasting effect", and "ultraviolet blocking effect".

[0059] 〔Manufacturing method〕 (1): Ingredients 1 to 25 are uniformly dispersed with a Henschel mixer. (2): Ingredients 26 to 32 are uniformly mixed. (3): (2) is added to (1), and after uniform dispersion, it is pulverized to obtain a solid powder foundation.

[0060] [Evaluation: "Lack of burden when spreading on the skin", "Effect of uniformly concealing spots and color unevenness", "Natural finish", "Lack of dryness over time", "Cosmetic retention effect"] Twenty professional cosmetic evaluation panelists were asked to use the powder foundations of Examples 1 to 16 and Comparative Examples 1 to 9, and for "Lack of burden when spreading on the skin", "Effect of uniformly concealing spots and color unevenness", "Natural finish", and "Cosmetic retention effect", each evaluated them on a 5-point scale according to the following criteria, scored each powder foundation, and further determined the average score of all panelists according to the following judgment criteria. For the "Cosmetic retention effect", the state 6 hours after applying the powder foundation (in daily life) was evaluated in comparison with the state immediately after application. 〔Evaluation Criteria〕: (Evaluation Results): (Score) Very Good: 5 points Good: 4 points Average: 3 points Slightly Poor: 2 points Poor: 1 point 〔Judgment Criteria〕: (Average Score): (Judgment) 4.0 or higher: ◎ 3.0 or higher to less than 4.0: ○ 2.0 or higher to less than 3.0: △ Less than 2.0: ×

[0061] [Evaluation: "UV Blocking Effect"] For the powder foundations of Examples 1 to 16 and Comparative Examples 1 to 9, after applying 2 mg / cm on a PMMA plate 2 and allowing the sample to stand for 20 minutes, SPF measurement was performed using an SPF analyzer (UV-2000S manufactured by Labsphere). (a) Four-level Evaluation Criteria (Evaluation): (Judgment) SPF value = 20 or higher: ◎ SPF value = 15 or higher to less than 20: ○ SPF value = 8 or higher to less than 15: △ SPF value = less than 8: ×

[0062] As is clear from the results in Table 2, the powder foundations of Examples 1 to 16, which are the products of the present invention, are excellent powder cosmetics in all items of "no burden when spreading on the skin", "effect of uniformly concealing spots and color unevenness", "natural finish", "no dry feeling over time", "makeup lasting effect", and "UV blocking effect". On the other hand, as is clear from the results in Table 3, in Comparative Example 1 where Component (A) was not blended, and in Comparative Examples 2 and 3 where Production Comparative Examples 2 and 4 were blended instead of Component (A), the effects of "uniformly concealing spots and color unevenness", "makeup persistence effect", and "UV blocking effect" were low. Furthermore, Comparative Example 4 containing fine particle metal oxide and Component (D) instead of Component (A) was inferior in terms of "lack of burden when spreading on the skin", "natural finish", "lack of dry feeling over time", and "makeup persistence effect". These are all presumably because Component (A) was not uniformly applied to the dermal papilla, there was no concealing effect of Component (A), and the makeup effect decreased. Comparative Example 5 containing no Component (C) but containing metal oxide instead did not satisfy the effects of "lack of burden when spreading on the skin", "uniformly concealing spots and color unevenness", and "makeup persistence effect". Comparative Examples 6 and 7 not containing Component (B) were inferior in terms of "uniformly concealing spots and color unevenness", "natural finish", and "makeup persistence effect". This is presumably because the sebum absorption ability of Component (B), which is considered to exist in the skin grooves, was poor, and the makeup film could not be sustained due to sebum secretion over time. Furthermore, Comparative Example 9 containing particles larger than Component (C) was even inferior in terms of "lack of burden when spreading on the skin". Comparative Example 8 not containing Component (C) but increasing the amount of Component (A) had a high "UV blocking effect", but was inferior in terms of "lack of burden when spreading on the skin" and "makeup persistence effect".
