Description

Silica-coated plate-like powder and cosmetics

[0001] The present invention relates to a silica-coated plate-like powder coated with layers of mesoporous silica, and to a cosmetic composition containing the same.

[0002] One of the purposes of cosmetics is to make the skin look smooth and beautiful by concealing morphological problems such as wrinkles, pores, and rough texture, as well as discoloration problems such as blemishes and freckles. In recent years, emphasis has been placed on a natural, unartificial finish (bare skin feel). A natural finish of cosmetics is evaluated when it is free of unnatural gloss (luster), has excellent uniformity of cosmetic film application, and has high transparency. Many new materials and technologies have been proposed to achieve a natural finish while maintaining the effects of the aforementioned makeup cosmetics. In particular, cosmetics containing various diffuse reflective powders are known as a method for concealing morphological problems.

[0003] Powders used in cosmetics can be broadly divided into spherical, plate-like, and irregular shapes. Spherical powders primarily provide slipperiness and a soft focus effect, while plate-like powders provide smoothness. Most plate-like powders have a glossy appearance. Some have a less glossy appearance, but have a higher hiding power. Irregular particles, which vary in particle shape, are difficult to apply evenly, feel unpleasant to the touch, and produce an unnatural finish.

[0004] On the other hand, substances with a porous structure on the powder surface have a large surface area and are therefore widely used as catalyst carriers and carriers for immobilizing enzymes, functional organic compounds, etc. Powders with a porous structure are also used in cosmetics, where they are used to prevent makeup from coming off by absorbing sebum from the skin.

[0005] Mesoporous powders with mesopores have been developed as porous bodies with uniform, fine pores, and their use is attracting attention. Patent Document 1 states that blending mesoporous powders can improve the long-lasting effect of makeup, but because the powders have an irregular shape, blending them into cosmetics can result in poor uniform dispersion, poor adhesion to the skin during application, and a rough feeling after application. Patent Document 2 discloses that mesoporous silica can be made into a layer or sheet shape, but these also cause a rough feeling when blended into cosmetics, and improvements to the feel during use are needed. Patent Documents 3 and 4 disclose spherical particles and hollow composite powders with mesoporous structures, but neither report on usability.

[0006] Japanese Patent Laid-Open No. 10-152317 Japanese Patent Laid-Open No. 2008-266049 Japanese Patent Laid-Open No. 2008-063209 Japanese Patent Laid-Open No. 2008-174435

[0007] The present invention has been made in view of the above circumstances, and aims to provide a composite powder and a cosmetic which are easy to use when applied, can correct unevenness of the skin, can provide a natural finish with a translucent feel with reduced gloss, and have an excellent effect of maintaining a cosmetic coating film.

[0008] As a result of intensive research into solving the above-mentioned problems, the present inventors have found that when a composite powder in which a plate-like powder is coated with a layer of mesoporous silica is incorporated into a cosmetic, the cosmetic is easy to apply, corrects unevenness of the skin, and provides a natural finish with a subdued shine and transparency, and has the effect of maintaining the cosmetic coating film, which has led to the completion of the present invention.

A method for producing a silica-coated plate-like powder coated with a layer of porous silica, comprising the following steps: Step (1): A step of preparing an aqueous solution containing a cationic surfactant at a concentration of 5 times or less the critical micelle concentration.

Step (3): A step of calcining the obtained silica-coated plate-like powder coated with a mesoporous silica layer to remove the cationic surfactant.

[0010] The silica-coated plate-like powder of the present invention provides a cosmetic product that is easy to apply, corrects unevenness of the skin, provides a natural finish with a subdued sheen, and has the effect of maintaining a cosmetic coating film.

[0011] The present invention is described in detail below. In the present invention, ingredient names may be written as cosmetic product names or International Nomenclature of Cosmetic Ingredients (INCI). When the cosmetic product name corresponds to the INCI, the cosmetic product name or English name may be omitted. The present invention relates to a silica-coated plate-like powder coated with a layer of mesoporous silica. The powder of the present invention is particularly useful when applied to cosmetics, but its use is not limited thereto.

[0012] [Plate-like powder] The plate-like powder to be coated will now be described. "Plate-like powder" refers to powder particles having a plate-like shape. When used in cosmetics, they provide excellent adhesion to the skin and smoothness when applied to the skin. Furthermore, because the plate-like powder has a flat surface, it strongly reflects the light that strikes it on the surface of the cosmetic coating film. Since light is reflected in one direction without diffusing, the reflected light is intensified, and when used in cosmetics, they have the effect of improving gloss. In addition, in the present invention, the plate-like powder is coated with a layer of mesoporous silica, thereby imparting a sense of transparency with reduced gloss.

[0013] The thickness of the plate-like powder of the present invention is defined by the aspect ratio [(particle major axis diameter) / (particle minor axis diameter)]. The thickness of the plate-like powder of the present invention is not particularly limited, but is preferably 3 to 500, more preferably 10 to 300. The aspect ratio can be measured by observation using a scanning electron microscope or a transmission electron microscope. The size of the plate-like powder is not particularly limited, but the average particle diameter is preferably 1 to 100 μm, more preferably 1 to 50 μm, and even more preferably 3 to 40 μm. The average particle diameter refers to the volume median diameter (D50). The volume median diameter (D50) is the particle diameter corresponding to 50% of the cumulative distribution when the volume particle size distribution is expressed as a cumulative distribution. The volume median diameter refers to a value measured, for example, using a laser diffraction / scattering particle size distribution analyzer.

[0014] The plate-like powder is not particularly limited as long as it is one that is generally used in cosmetics, and examples thereof include minerals, metal oxides, metals, glass, etc., and it can be used alone or in combination of two or more types.

[0015] Examples of minerals include talc, mica, kaolin, etc., metal oxides include silica, metals include gold and silver, glass includes borosilicate (Ca / Al), and other plate-like powders that can be incorporated into cosmetics include barium sulfate and boron nitride, but mica is preferred because it has a refractive index close to that of skin, and has transparency and a moderate gloss when applied to the skin. Any mica that is commonly used in cosmetics can be used without any particular restrictions. Specifically, mica series such as TM-10, TM-20, Y-1800, Y-2300, Y-2300X, Y-2400, Y-3000, SA-110, SA-310, SA-350, FA-450, NCC-322, and NCF-322 (manufactured by Yamaguchi Mica Co., Ltd.), RONAFLAIR series such as RONAFLAIR Mica M and RONAFLAIR Silk Mica (manufactured by Merck & Co., Inc.), Mearlmica CF, Mearlmica Other examples that can be suitably used include the Mearlmica series such as SV (manufactured by Merck), the sericite powder series such as FSE, FSE-S, FSN, NSP, JS-A, and JS-1 (manufactured by Japan Sericite Co., Ltd.), the Eight Pearl series such as Eight Pearl 300S, Eight Pearl 300SW, and Eight Pearl 300S-S (manufactured by Kakuhachi Gyorinhaku Co., Ltd.), Sericite DN-MC (manufactured by Dainippon Kasei Co., Ltd.), and the GMS series such as Sericite GMS-C and Sericite GMS-4C (manufactured by Kinsei Matec Co., Ltd.).

[0016] [Silica-coated plate-like powder coated with a layer of mesoporous silica] In the present invention, the plate-like powder is coated with a layer of mesoporous silica. "Coated in a layer" means that the silica does not take a particle shape on the powder surface, which has the effect of suppressing the brightness of the plate-like powder.

[0017] In the present invention, the silica layer coating the plate-like powder has mesoporous pores. In the present invention, mesoporous pores refer to pores with a diameter of 50 nm or less. The pore diameter can be selected appropriately and may be less than 2 nm, 0.5 nm or more but less than 2 nm, 2 to 50 nm, or 2 to 10 nm. The lower limit is not particularly limited and may be 0.1 nm. Compared to typical silica coating layers, the mesoporous silica layer has smaller pores and a larger specific surface area, thereby maintaining the effects of the cosmetic coating film through light scattering and sebum absorption. The pore diameter is measured by the BJH method using a high-precision gas adsorption analyzer. The pore diameter can be adjusted appropriately, for example, by selecting the temperature and time in steps (3) and (3') described below.

[0018] [Method for producing silica-coated plate-like powder] The method for producing the silica-coated plate-like powder of the present invention will be described in detail below, although the production method is not limited thereto.

[0019] The method for producing silica-coated plate-like powders of the present invention comprises the following steps (1) to (3): Step (1): preparing an aqueous solution containing a cationic surfactant at a concentration of not more than 5 times the critical micelle concentration; Step (2): immersing plate-like powders in the aqueous solution obtained in Step (1), adding a silica source that generates a silanol compound by hydrolysis to a concentration of 10 to 500 mmol / L, and stirring at a temperature of 0 to 100°C to coat the surfaces of the plate-like powders in the form of a mesoporous silica layer; Step (3): removing the cationic surfactant from the silica-coated plate-like powders coated with the obtained mesoporous silica layer. Each step and the components used therein will be described below.

[0020] [Step (1)] Step (1) is a step of preparing an aqueous solution of a cationic surfactant. In this production method, mesoporous silica is formed by using this aqueous solution. The cationic surfactant is used to form a mesoporous structure and to disperse silica particles and plate-like powder. Known cationic surfactants can be used here. As the cationic surfactant, alkyltrimethylammonium salts represented by the following formula (1) are preferred. (wherein R is an alkyl group having 1 to 22 carbon atoms, and Z is a monovalent anion.)

[0021] R is an alkyl group having 1 to 22 carbon atoms, preferably 8 to 15 carbon atoms, and more preferably 10 to 13 carbon atoms. The alkyl group may be linear, branched, or cyclic. Specific examples thereof include methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, s-butyl, t-butyl, n-pentyl, n-hexyl, cyclohexyl, n-heptyl, n-octyl, n-nonyl, n-decyl, n-undecyl, n-dodecyl, 2-methylundecyl, n-tridecyl, n-tetradecyl, n-pentadecyl, n-hexadecyl, n-heptadecyl, and n-octadecyl.

[0022] Z is a monovalent anion, preferably a halide ion, hydroxide ion, nitrate ion or sulfate ion, more preferably a halide ion, and even more preferably a chloride ion or bromide ion.

[0023] The cationic surfactant represented by the formula (1) is preferably an alkyltrimethylammonium salt. Specific examples thereof include butylammonium chloride, hexyltrimethylammonium chloride, octyltrimethylammonium chloride, decyltrimethylammonium chloride, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, hexadecyltrimethylammonium chloride, stearyltrimethylammonium chloride, butyltrimethylammonium bromide, hexyltrimethylammonium bromide, octyltrimethylammonium bromide, decyltrimethylammonium bromide, dodecyltrimethylammonium bromide, tetradecyltrimethylammonium bromide, hexadecyltrimethylammonium bromide, and stearyltrimethylammonium bromide. Among these, dodecyltrimethylammonium chloride is preferred from the viewpoint of forming a uniform mesoporous structure.

[0024] From the viewpoint of powder dispersibility, the content of the cationic surfactant in the aqueous solution in step (1) is preferably 5 times or less, more preferably 4 times or less, and even more preferably 3 times or less, the critical micelle concentration of the cationic surfactant used in water at 20°C.

[0025] Step (2): Immersing the plate-like powder in the aqueous solution obtained in Step (1), adding a silica source that generates a silanol compound upon hydrolysis to a concentration of 10 to 500 mmol / L, and stirring at a temperature of 0 to 100°C to coat the surface of the plate-like powder with a mesoporous silica layer. The silica source concentration is 10 to 500 mmol / L, preferably 50 to 250 mmol / L, and more preferably 75 to 200 mmol / L. The temperature is 0 to 100°C, more preferably 5 to 80°C. The stirring time of the solution in Step (2) varies depending on the temperature, but is typically selected appropriately from 0.1 to 24 hours. The silica source is not particularly limited as long as it generates a silanol compound upon hydrolysis, but examples include tetramethyl orthosilicate, tetraethyl orthosilicate, and tetraisopropyl orthosilicate. Among these, tetramethyl orthosilicate such as tetramethoxysilane is preferred.

[0026] Step (3): Removing the Cationic Surfactant from the Obtained Silica-Coated Plate-Like Powder Coated with a Mesoporous Silica Layer In step (3), the plate-like powder coated with the mesoporous silica layer obtained in step (2) is removed from the aqueous solution, washed with water, dried, if necessary, and then the cationic surfactant is removed from the plate-like powder. Methods for removing the cationic surfactant include extraction and calcination. In the extraction method, the mesoporous silica layer-coated substrate is placed in an aqueous solution having a pH of 1 to 4 and a temperature of 25 to 80°C, and the solution is stirred for 1 to 48 hours, preferably 2 to 24 hours, and more preferably 3 to 16 hours, to extract the cationic surfactant. However, it is difficult to completely remove the cationic surfactant using the extraction method. In the calcination method, the cationic surfactant can be removed by calcining in an electric furnace or the like, preferably at 400 to 700°C, more preferably at 500 to 650°C, for 1 to 10 hours.

[0027] The proportion of mesoporous silica is preferably 10 to 60% by mass, more preferably 20 to 40% by mass, relative to 100% by mass of the silica-coated plate-like powder. If the proportion is 10% by mass or more, the effect of the coated silica layer is exerted, and if the proportion is 60% by mass or less, the layer thickness is appropriate and the powder particles do not aggregate together. This makes it easy to uniformly disperse and apply, and improves usability.

[0028] [Spherical Silica-Immobilized Silica-Coated Composite Powder] The silica-coated plate-like powder of the present invention preferably further has spherical silica immobilized on its surface. Immobilizing the spherical silica not only further improves usability and the light scattering effect of correcting skin irregularities, but also imparts high slip properties. Furthermore, immobilization can prevent the spherical silica from peeling off from the coated silica surface. Furthermore, the spherical silica-immobilized silica-coated composite powder is preferably plate-shaped.

[0029] [Spherical Silica] The spherical silica of the present invention will now be described. When silica particles are spherical, they act as a kind of ball bearing when applied to cosmetics, dramatically improving the slipperiness of the composite powder. They also effectively scatter light on the surface of the cosmetic coating film, thereby concealing skin morphological problems related to light reflection (a soft focus effect).

[0030] In the spherical silica of the present invention, "spherical" includes not only perfect spheres but also slightly distorted spheres. The shape of such particles can be evaluated as the circularity when the particles are projected two-dimensionally. In the present invention, circularity refers to the average value of the minor axis / major axis ratios obtained by measuring the major axis and minor axis of 30 randomly selected particles using particle images observed with a scanning electron microscope (SEM). Here, "spherical" in the present invention particularly refers to a circularity in the range of 0.8 to 1, preferably 0.85 to 1, and more preferably 0.90 to 1.

[0031] The average particle size of the spherical silica may be, for example, 80 to 550 nm, preferably 100 to 500 nm, and more preferably 200 to 500 nm. The average particle size referred to here refers to the volume median diameter (D50). The volume median diameter (D50) is the particle diameter corresponding to 50% of the cumulative volume when the volume particle size distribution is expressed as a cumulative distribution. The volume median diameter refers to a value measured, for example, with a laser diffraction / scattering particle size distribution analyzer. Within this range, the light scattering effect of the immobilized spherical silica is obtained, and the effect of correcting unevenness of the skin is achieved. Furthermore, this is preferable because the contact area with the skin is reduced, resulting in excellent slipperiness.

[0032] The spherical silica in the present invention may be hydrophobic spherical silica obtained by subjecting its surface to hydrophobic treatment. Alternatively, it may be used without surface treatment in its hydrophilic state. When dispersed in an aqueous component, hydrophilic spherical silica is preferred, and when dispersed in an oily component, hydrophobic spherical silica is preferred.

[0033] The spherical silica in the present invention may be non-porous or porous, and may be microporous, mesoporous, or microporous. When non-porous, it has good slipperiness on the skin and good spreadability, while when porous, it has a large specific surface area and is expected to have a soft focus effect.

[0034] As the silica, silica, hydrous silica, dimethicone silicate, dimethyl silylated silica, etc., as defined by the cosmetic labeling name, can be suitably used.

[0035] The method for producing spherical silica in the present invention is not particularly limited, and can be carried out by a known method such as a sol-gel method. The sol-gel method is a production method that includes adding a tetrafunctional silane compound to a mixture of a hydrophilic organic solvent such as alcohol, water, and a basic substance, reacting them to obtain a solvent dispersion containing hydrophilic spherical silica microparticles, and then drying the solvent to obtain a powder.

[0036] It is preferred that the spherical silica be chemically fixed to the surface of the silica-coated plate-like powder. The method for fixing the spherical silica to the surface is not particularly limited, but a method using a binder is preferred. By forming a composite powder in which spherical silica is fixed to the surface of a silica-coated plate-like powder coated with a binder layer, the spherical silica is fixed to the powder surface and is less likely to fall off from the surface, making it possible to impart a better feel to the product. Chemical fixation prevents the spherical silica fixed to the substrate from peeling off due to mechanical stress during cosmetic production, making it possible to maintain its effectiveness even after the cosmetic production process.

[0037] Examples of binders include commonly used silane coupling agents such as alkoxysilanes and their partial hydrolysates. When a partial hydrolysate of a silane coupling agent is used as a binder, it may be attached to the surface of the plate-like powder in the form of a film or particles. It may also be attached partially or entirely to the surface of the plate-like powder, the surface of the spherical silica, or both surfaces. In particular, it is preferable that it is attached as a film to the entire interface between the silica-coated plate-like powder and the spherical silica.

[0038] [Method for Fixing Spherical Silica to Silica-Coated Plate-Like Powder] The method for fixing spherical silica to the silica-coated plate-like powder in the present invention is not particularly limited, but examples thereof include the following methods.

[0039] The method for producing a spherical silica-immobilized silica-coated composite powder comprises the following steps (1) to (3): step (1): preparing an aqueous solution containing a cationic surfactant at a concentration of 5 times or less the critical micelle concentration; step (2'): immersing a silica-coated plate-like powder in the aqueous solution obtained in step (1), adding 1 to 50% by mass of spherical silica having a median diameter of 0.1 to 1 μm relative to 100% by mass of the silica-coated plate-like powder, and further adding a silica source that generates a silanol compound by hydrolysis to a concentration of 10 to 500 mmol / L, and stirring at a temperature of 0 to 100° C. to immobilize the spherical silica on the surface of the silica-coated plate-like powder; and step (3'): removing the cationic surfactant from the obtained spherical silica-immobilized silica-coated composite powder.

[0040] Step (1) Step (1) is the same as step (1) in the above-mentioned method for producing silica-coated plate-like powder.

[0041] Step (2'): A step of immersing the silica-coated plate-like powder in the aqueous solution obtained in Step (1), adding spherical silica having a median diameter of 0.1 to 1 μm in an amount of 1 to 50% by mass relative to 100% by mass of the silica-coated plate-like powder, and further adding a silica source that generates a silanol compound by hydrolysis to a concentration of 10 to 500 mmol / L, and stirring the mixture at a temperature of 0 to 100° C. to fix the spherical silica on the surface of the silica-coated plate-like powder.

[0042] The amount of spherical silica added (adhesion amount) is preferably 5 to 25% by mass, more preferably 7.5 to 20% by mass, and even more preferably 10 to 15% by mass, relative to 100% by mass of the silica-coated plate-like powder coated with a layer of mesoporous silica. By setting this amount to 5% by mass or more, the light scattering effect is further improved, and by setting it to 25% by mass or less, the effect of the substrate is obtained while the light scattering effect is obtained, resulting in a more natural finish.

[0043] The concentration of the silica source is 10 to 500 mmol / L, preferably 50 to 250 mmol / L, and more preferably 75 to 200 mmol / L. The temperature is 0 to 100°C, more preferably 5 to 80°C. The stirring time of the solution in step (2) varies depending on the temperature, but is usually selected appropriately from 0.1 to 24 hours. As the silica source, those listed in step (2) of the above method for producing silica-coated plate-like powder can be used in the same way.

[0044] Step (3'): Removal of the cationic surfactant from the obtained spherical silica-immobilized, silica-coated composite powder. In step (3'), the spherical silica-immobilized, silica-coated composite powder obtained in step (2) is removed from the aqueous solution, washed with water, dried, and then the cationic surfactant is removed from the composite powder. Methods for removing the cationic surfactant include extraction and calcination. In the extraction method, the composite powder is placed in an aqueous solution at a pH of 1 to 4 and a temperature of 25 to 80°C, and stirred for 1 to 48 hours, preferably 2 to 24 hours, and more preferably 3 to 16 hours, to extract the cationic surfactant. However, it is difficult to completely remove the cationic surfactant using the extraction method. In the calcination method, the cationic surfactant can be removed by calcining in an electric furnace or the like, preferably at 400 to 700°C, more preferably at 500 to 650°C, for 1 to 10 hours.

[0045] [Physical Properties of Silica-Coated Plate-Like Powder] The silica-coated plate-like powder of the present invention (including spherical silica-immobilized silica-coated composite powder) has a specific surface area of ​​10 to 400 m2 as measured by the BET method. 2 / g is preferred, and 20 to 200m 2 / g is more preferable. 2 / g or more, the light scattering property and oil absorption property are further improved. 2 By making the content of the polymer film 100% by mass % or less, the light scattering property and oil absorbency can be further improved, and the dry feeling can be suppressed.

[0046] The thickness of the silica-coated plate-like powder of the present invention is defined by the aspect ratio [(major axis diameter of particle) / (minor axis diameter of particle)]. The thickness of the silica-coated plate-like powder of the present invention is not particularly limited, but is preferably 3 to 500, more preferably 10 to 300. The size of the silica-coated plate-like powder is not particularly limited, but the average particle diameter is preferably 1 to 100 μm, more preferably 1 to 50 μm, and even more preferably 3 to 40 μm.

[0047] As the silica-coated plate-like powder, composite particles are preferred, in which mica is coated with a layer of mesoporous silica and spherical silica is chemically fixed. This provides the spherical silica on the surface with smoothness and the effect of correcting skin irregularities, while the mica and spherical silica suppress unnatural shine. When incorporated into foundations and other products, this can provide a natural finish with reduced shine and a translucent appearance. In addition to the effect of achieving a natural finish, the high specific surface area is expected to improve oil absorption and absorb sebum, thereby maintaining the cosmetic coating film. Furthermore, chemical fixation increases the strength of the composite powder, enabling it to withstand the mechanical stress expected in the cosmetic manufacturing process, without compromising the effects of the composite powder of the present invention.

[0048] The silica-coated plate-like powder of the present invention can be surface-treated with a silylating agent, silicone oil, waxes, paraffins, organic fluorine compounds, surfactants, etc. to impart or improve water repellency or improve dispersibility in oils. The treating agent (hydrophobic treating agent) for the hydrophobic surface treatment is not particularly limited as long as it can impart hydrophobicity, and examples include silicone treating agents, waxes, paraffins, organic fluorine compounds such as perfluoroalkyl phosphates, surfactants, amino acids such as N-acyl glutamic acid, and metal soaps such as aluminum stearate and magnesium myristate. These can be used alone or in combination of two or more.

[0049] Among these, silicone treatment agents are preferred, and examples thereof include silanes or silylating agents such as triethoxycaprylylsilane (INCI) and trimethoxysilyl dimethicone (INCI), dimethicone (INCI), methicone (INCI), hydrogen dimethicone (INCI), triethoxysilylethyl polydimethylsiloxyethyl dimethicone (INCI), triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone (INCI), and (acrylates / tridecyl acrylate / triethoxysilylpropyl methacrylate / dimethicone methacrylate) copolymer (labeled name (INCI: Acrylates / Tridecyl Acrylate / Triethoxysilylpropyl Methacrylate / Dimethicone Methacrylate) copolymer). Copolymer), etc. In particular, the silicone powder treating agent described in Japanese Patent No. 3912961 is preferably used. Specific examples of these silicone treating agents include AES-3083, KF-99P, KF-9901, KF-9908, KF-9909, KP-574, KP-541, etc., manufactured by Shin-Etsu Chemical Co., Ltd. Among them, triethoxysilylethyl polydimethylsiloxyethylhexyl dimethicone (KF-9909, manufactured by Shin-Etsu Chemical Co., Ltd.), which is a dimethylpolysiloxane having triethoxysilyl groups, polydimethylsiloxyethyl groups, and hexyl groups in its side chains, is preferred, from the viewpoint of exhibiting high affinity even when the dispersion medium for dispersing the powder is silicone, hydrocarbon, or a mixture thereof.

[0050] [Surface Treatment Method] The method for surface treating the silica-coated plate-like powder of the present invention using a hydrophobic treatment agent is not particularly limited and can be carried out by any known method. Surface treatment methods can be broadly divided into dry methods and wet methods. In the dry method, for example, the silica-coated plate-like powder of the present invention can be treated by mixing / contacting the hydrophobic treatment agent with any stirrer, grinder, mixer, or disperser, such as a Henschel mixer, ball mill, jet mill, kneader, planetary mixer, sand mill, attritor, ribbon blender, disperser mixer, or homomixer. During this treatment, energy such as heat, mechanochemical mechanical force, or superheated steam may be applied. Alternatively, after thoroughly mixing / contacting the composite powder of the present invention with the hydrophobic treatment agent, energy such as heat, mechanochemical mechanical force, or superheated steam may be applied separately to treat the composite powder of the present invention.
