Description

  In the present invention, the surface of the pearl pigment formed by forming a metal oxide coating layer containing titanium oxide on the surface of the flaky substrate (A) as a constituent component is entirely made of spherical organic powder having a particle diameter of 200 to 400 nm. Composite powder coated with 2.0 to 10.0% by weight, (B) a fluorine-containing copolymer obtained by polymerizing a fluorine-containing monomer and an alkylene glycol (meth) acrylate monomer, and / or fluorine-containing A fluorine-containing copolymer obtained by polymerizing a monomer, an alkylene glycol (meth) acrylate monomer, and a di (meth) acrylate that is a crosslinkable monomer is 1 to 15% by weight based on the weight of the powder. The present invention relates to a powder for cosmetics obtained by coating treatment, and (C) a solid powder cosmetic having a facial lift-up effect, a makeup, and a high moisturizing effect, containing an oily component that is pasty at 25 ° C.

  Conventionally, makeup cosmetics have functions to hide skin spots, freckles, color unevenness, dullness, conspicuous pores, wrinkles, etc., to make the skin look beautiful and to change the texture. However, as we enter an aging society, in addition to these functions, the function of hiding facial and skin sagging with age, wrinkles, etc. and making it appear as a youthful face will be important in the coming years. Conceivable.

  Among these, it is important to give the face a three-dimensional effect in order to hide the slack and give a youthful impression. For that purpose, the face is divided into upper and lower parts, using a foundation with different color tones at the top and bottom, and applied so that the brightness of the makeup cosmetics on the top is higher than the one on the bottom, shading, and the face line is clean How to show (Patent Document 1), by applying a foundation cosmetic blended with a mica titanium pigment that does not have interference color colored with low-order titanium oxide, and then the foundation is overlaid, the face line and nose are clearly shown A method of increasing the three-dimensional effect (Patent Document 2), a method of blending a fine pearl pigment and a spherical resin powder into a foundation or a makeup base with an optimal amount and an optimal mixing ratio (Patent Document 3), and the like are shown.

  However, in the method of painting differently depending on the location of the face as in Patent Document 1, the delicate boundary of the cosmetic coating is concerned, and it is difficult to say that the finish is natural, and in the method of Patent Document 2, makeup cosmetics are not used. Because they are used in combination, make-up techniques are required, and it is difficult to create a lifted impression. Furthermore, in the method as disclosed in Patent Document 3, the regular reflection of the light of the pearl pigment and the diffuse reflection of the light of the spherical resin powder cancel each other's light characteristics and do not give a sufficiently youthful impression. It was.

  In addition, a shadow appears due to sagging of the face from the nose to the lower part of the cheek around the mouth, and if this shadow recognizes sagging, it has the effect of a reflex board that makes this shadow disappear and looks rejuvenated A composite powder is also introduced in Patent Document 4.

  However, with the use of this composite powder, the brightness of the parent mica titanium is greatly reduced due to the composite, and the face shadow actually decreases, but on the contrary, the face appears to expand. It gave a fat impression.

  Further, as to wrinkles on the skin and conspicuous pores, the pearl pigment is polished with a composite powder in which spherical fine particles of acrylic resin are coated at a concentration of 40 to 60% by weight as in Patent Document 5. Although the intensity of uniform diffuse reflection is controlled by suppressing the natural light, the skin is natural and transparent, but the light reflected from the face is still widened and the face is blurred. It tends to look like it and emphasizes the sagging of the skin.

  On the other hand, as described above, the effect of making the skin look beautiful when makeup is lost due to sweat and sebum, especially in the spring and summer, even if a device that hides corners, sagging skin, wrinkles, etc. is applied. The reality is that the remarkably decreases.

  For this reason, attempts have been made so far to improve the water resistance and oil resistance of the powder blended in cosmetics and to prevent makeup slippage due to sweat, sebum and the like.

  As a method for preventing makeup loss due to sweat, a silicone treatment for imparting water resistance to powder has been conventionally known. Specifically, a method in which methylhydrogenpolysiloxane is mixed with a powder and baked (Patent Document 6), methylhydrogenpolysiloxane or dimethylpolysiloxane is dissolved in an organic solvent, and zinc octylate is used as a crosslinking catalyst. There are known a method of adding and baking (Patent Document 7), a method of coating a powder with a metal hydroxide, and further treating with methylhydrogenpolysiloxane by a mechanochemical reaction (Patent Document 8). However, cosmetics blended with these treated powders are not particularly oil-resistant and have caused makeup loss due to sebum produced on the skin.

  Therefore, in order to improve both the water resistance and oil resistance of the powder, in recent years, a method of treating the powder with a fluorine compound has been used. Specifically, a method of treating with Teflon (registered trademark) (Patent Document 9), a method of treating with fluorinated acrylate (Patent Document 10), and a method of treating with perfluoroalkyl phosphate diethanolamine salt (Patent Document 11) And a method of treating with perfluoroalkylsilane (Patent Document 12, Patent Document 13) and the like have been proposed.

  Since these powders are all coated with a fluorine compound having a very small surface free energy, they have strong water and oil repellency. However, in the method of treating with the above-mentioned Teflon (registered trademark), since the adhesion to the skin is low, the makeup coating peels off over time and the makeup is poor. In the method of treating with fluorinated acrylate, a squeaky sensation when applying cosmetics is likely to occur, and breakage due to sebum has not been improved. Perfluoroalkyl phosphate diethanolamine salt is the most commonly used fluorination treatment, but it is surprisingly damaged by sweat, and after some time has passed since application, Make-ups such as slipping and dusting were also likely to occur. In particular, breakage due to the drying occurred frequently in a well-operated room such as an air conditioner even in summer. Further, in the perfluoroalkylsilane treatment, both water resistance and oil resistance were good, but this also had low adhesion to the skin and easily caused makeup loss due to drying.

  On the other hand, a fluorine-containing compound having a perfluoroalkyl group generally has a low reflection property due to its high refractive index, as shown in Non-Patent Document 1, and is surface-treated with a fluorine-containing compound. In the case where the powder is blended in cosmetics, there is a disadvantage in the makeup cosmetics that have come to produce the texture of skin using various reflections of light. In particular, when used in combination with a powder having a strong regular reflection such as a pearl pigment, there is a strong tendency to weaken the reflected light, which may damage the gloss of the skin.

  Based on the above situation, makeup cosmetics targeted at women who are particularly concerned about facial aging and skin sagging, etc., while having the function of showing a glossy, youthful face However, there has been a demand for the development of an excellent makeup cosmetic that is excellent in makeup without sacrificing its glossiness and that does not break down due to drying even in a room where a summer air conditioner works well.

  Therefore, the object of the present invention is to have a makeup effect that lifts up the face and makes you look younger, but also has a long lasting makeup effect, i.e., without losing the gloss, sweat and sebum An object of the present invention is to provide a solid powder cosmetic that is strong and also resistant to breakage due to drying.

  As a result of intensive research in view of such circumstances, the inventors of the present invention have developed a pearl pigment obtained by forming a metal oxide coating layer containing titanium oxide on the surface of a flaky substrate (A) as a constituent component. A composite powder having a surface coated with a spherical organic powder having a particle size of 200 to 400 nm in an amount of 2.0 to 10.0% by weight; and (B) a polymer surface treatment agent of a specific fluorine-containing copolymer on the surface. And (C) a solid powder cosmetic containing a paste-like oily component at 25 ° C., and further to this solid powder cosmetic, potassium aluminum sulfate dodecahydrate and / or chloride as an additive. If it is a solid powder cosmetic containing sodium, applying it will give the youthful impression that the face is lifted up more than before, but there is no makeup loss due to sweat or sebum, Even dry Makeup even without such as slipping or powdering of cosmetic film by, found that excellent duration of makeup effect, and have completed the present invention.

  That is, in general, a compound having a perfluoroalkyl group is said to be low-reflective, and despite the fact that it is expected to suppress the reflected light that produces the three-dimensional effect of the face, the pearl pigment is made into a spherical organic substance as described above. In a solid powder cosmetic containing a composite powder coated with a powder, a powder treated with a polymer surface treatment agent of a specific fluorine-containing copolymer, and a paste-like oily component at 25 ° C., the pearl pigment is a spherical organic powder. The brightness of reflected light and the angle-dependent reflection characteristics that produce the three-dimensional effect exhibited by the composite powder coated with the body can be reversed without weakening the powder treated with the polymer surface treatment agent of the fluorinated copolymer. While further enhancing, it has been found that makeup slippage due to sweat and sebum, as well as makeup slippage such as slipping and powdering of the makeup film due to drying is prevented, and it also has excellent three-dimensional feeling and lift-up feeling, If it is a solid powder cosmetic containing aluminum potassium sulfate dodecahydrate and / or sodium chloride as an additive to this, it is further excellent in the production and sustainability of a three-dimensional effect without impairing the glossiness of the skin. I found it.

  Hereinafter, the present invention will be described in detail.

  In the composite powder of the present invention, the pearl pigment formed by forming a metal oxide coating layer mainly composed of titanium oxide on the surface of a flaky substrate has a particle diameter of 1 to 150 μm and a thickness of 5 μm or less, preferably It is a pearlescent pigment in which titanium oxide having a crystalline form such as rutile or anatase is uniformly coated on the surface of a flaky substrate such as mica, synthetic mica or glass flakes of 1 μm or less. In addition, the present invention includes those that give interference color by changing the thickness of the titanium oxide layer to be coated, those that are coated with a part of titanium oxide replaced with iron oxide, and those that are further coated with silicic anhydride. Pearl pigment.

  This pearl pigment is a powder that emits strong luster and has an effect of making the face look brighter. However, a pearl pigment having a large particle diameter shines loosely on the skin, and the skin looks uneven and rough. Therefore, in order to make the skin look bright with a uniform coating film, a fine pearl pigment with a fine particle is preferable as the mother powder to be coated of the present invention, and the particle diameter of the pearl pigment is 60 μm or less. Among them, for example, commercially available products such as ULTIMICA SB-100, ULTIMICA SD-100, TIMIRON STARLUSTER MP-115, TIMIRON SUPERSHEEN MP-1001, TIMIRON SUPERSILK MP-1005, TIMONON SUPER GOLD, TIMDIRON ILDON ILDONI LONIDON PLD , TIMIRON FINE GOLD MP-20, COLORONA RED GOLD, COLORONA BRIGHT GOLD, TIMICA EX RA BRIGHT, FLAMENCO SATIN PEARL, FLAMENCO ULTRA SILK, FLAMENCO SATINA, FLAMENCO VELVET, FLAMENCO ULTRA FINE, FLAMENCO PEARL, FLAMENCO SUPER PEARL, FLAMENCO GOLD, FLAMENCO ORANGE, FLAMENCO SATIN GOLD, FLAMENCO SATIN ORANGE, FLAMENCO SUMMIT GOLD, CLOISONNE GOLD, CLOISONNE COPPER, CLOISONE SATIN COPPER, CLOISONE SATIN GOLD, CLOISONE NU-ANTIQUE GOLD, DUOCROME There are YG, DUOCROME YR, GEMTON TAN OPAL, etc., and the color tone is adjusted so as not to impair the brightness, and one or more of these pearl pigment series can be used.

  The spherical organic powder compounded on the surface of the pearl pigment of the present invention includes, for example, spherical particles made of organic natural products such as cellulose, polyethylene, nylon, poly (meth) acrylate, polystyrene, and methylsiloxane network polymer. It is a spherical polymer particle made of an organic compound such as In addition, the latter spherical powder by organic synthesis is a powder of a core shell structure in which a single polymer of these organic compounds or two or more kinds of copolymers, and further, different organic compounds are overlapped in two or more layers. is there. In the present invention, one or more of these spherical organic powders can be used.

  In the present invention, in order to brighten the entire face and brighten the convex part of the face to increase the gloss of the skin, it is possible to reduce the brightness of the pearl pigment due to coating, The purpose of this is to make specular reflection relatively stronger without diffusing, so that the particle diameter of the spherical organic powder is visible light that is less likely to scatter or block light, taking into account the average major axis of the pearl pigment used. One having a wavelength of 200 to 400 nm (average particle diameter by a dynamic light scattering method) corresponding to a wavelength slightly shorter than the above wavelength is used.

  The coating amount of the spherical organic powder on the surface of the pearl pigment in the present invention is 2.0 to 10.0% by weight in consideration of being able to change the reflection characteristics and not impairing the brightness of the pearl. is there.

  In the present invention, a commercially available spherical organic powder can be used. However, in consideration of obtaining a desired particle diameter, a polystyrene-based resin, poly (meth) acrylic, which can easily control the particle diameter by emulsion polymerization or the like. It is better to use an acid ester-based resin, a copolymer of two or more of these, or a powder having a core-shell structure. In particular, polymethyl methacrylate, methyl methacrylate cross polymer, acrylates cross polymer, acrylates copolymer, (styrene / DVB) copolymer (DVB: divinylbenzene) can be easily controlled to various particle sizes, and can be used in powders and emulsions. There are many commercially available dispersions dispersed in water.

  The method for producing a composite powder in which the pearl pigment in the present invention is coated with a spherical organic powder is as follows: (1) After mixing the pearl pigment and the spherical organic powder in a certain composition ratio, A method of spray drying at about 100 ° C., (2) A method in which a desired spherical organic powder is uniformly dispersed in an alcohol aqueous solution and then slurried by adding a pearl pigment, and spray-dried in the same manner. (3) An emulsion-like spherical shape A method in which the dispersion of the organic powder is uniformly dispersed in water and then further dispersed by adding a pearl pigment, and spray-dried in the same manner. (4) The spherical organic powder is uniformly dispersed in water together with a small amount of surfactant. (5) Emulsion by adding pearl pigment and dispersing further, adding a small amount of flocculant such as aluminum sulfate or polyaluminum chloride, filtering, washing and drying After uniformly dispersing the spherical organic powder dispersion in water, adding pearl pigment to further disperse, adding a small amount of flocculant such as aluminum sulfate or polyaluminum chloride, filtering, washing and drying However, there is no particular limitation as long as the spherical organic powder is fixed to the pearl pigment.

  The composite powder obtained by coating the pearl pigment with the spherical organic powder is subjected to various surface treatments such as metal soap treatment, silicone treatment, fluorine-containing compound treatment, amino acid treatment, etc. to impart water repellency and oil repellency. You may go and mix in cosmetics. These treatments may be used alone or in combination of two or more.

  The amount of the composite powder in which the pearl pigment blended in the makeup cosmetics is coated with the spherical organic powder is not particularly limited, but the whole face is brightened while the convex part of the face is brightened. In order to obtain a youthful impression that is lifted up without causing the face to appear to be relatively dark and the face to appear swollen, 0.5 to 15.0% by weight is preferable. In particular, 1.0% by weight or more is good if the cheeks appear to be raised while being more consciously bright. When it mixes exceeding 15.0 weight%, there exists a tendency for gloss to be too strong and it may look like metallic skin.

  Note that the characteristics of the powder itself of the composite powder obtained by coating the pearl pigment with the spherical organic powder and the knowledge when blended in the makeup cosmetics in general conform to Japanese Patent Application No. 2009-116742. A combination of a powder treated with a polymer surface treatment of a fluorocopolymer and a paste-like oily component, and the characteristics of the composite powder itself, in which the pearl pigment is coated with a spherical organic powder, is extracted with a solid powder cosmetic.

It is not something. Further, the dosage form of the fluorinated copolymer is preferably liquid, for example, a surface in which the fluorinated copolymer is dissolved or dispersed within a range of 1 to 50% by weight in a solvent comprising water or alcohol. The treatment form is easier to handle.

  It is preferable that the processing amount of the above-mentioned fluorine-containing copolymer to the powder is 1 to 15% by weight with respect to the weight of the powder to be processed. If the amount is less than 1% by weight, the water and oil repellency and makeup and the moisturizing effect are not sufficient. If the amount exceeds 15% by weight, aggregation between powders due to the polymer occurs.

  In the present invention, the method for surface-treating the powder using the fluorine-containing copolymer is not particularly limited, and can be performed by a known method. Broadly classified, there are wet methods and dry methods. In the wet method, powder is dispersed in an appropriate solvent, and a fluorine-containing copolymer or a surface treatment agent containing the same is added, and if necessary, other surface treatment agents and pH adjusters are added. , After stirring and mixing, refers to a technique obtained by removing the solvent by filtration, washing, and drying, and optionally pulverizing. Examples of the solvent include water, methanol, ethanol, isopropanol, acetone and the like. In addition, the dry method means that the surface treatment agent containing the fluorine-containing copolymer or the fluorine-containing copolymer is used as it is while mixing the powder with a stirring and mixing device such as a Henschel mixer, a jet mill, a ball mill, or a super mixer. A method obtained by diluting and adding to an appropriate solvent, mixing after stirring, drying, and optionally pulverizing. In addition, spray drying method, fluidized granulation method and the like can be mentioned, but any method may be used as long as the fluorine-containing copolymer is coated on the surface of the substrate powder.

  Any powder that is usually used as a cosmetic can be applied to the powder treated with the fluorine-containing copolymer in the present invention. For example, talc, mica, kaolin, sericite, bentonite, smectite, titanium mica, bismuth oxychloride, silicic acid, silicic anhydride, alumina, titanium oxide, fine particle titanium oxide, zinc oxide, zirconium oxide, magnesium oxide, barium sulfate, Magnesium sulfate, calcium carbonate, magnesium carbonate, aluminum silicate, magnesium silicate, calcium silicate, barium silicate, hydroxyapatite, boron nitride, metal soap, bengara, yellow iron oxide, black iron oxide, chromium oxide, chromium hydroxide , Inorganic powders such as carbon black, gunjou, conger, etc., nylon powder, polyalkyl acrylate, polyethylene powder, polystyrene, cellulose powder, cellulose acetate, polyurethane, divinylbenzene, styrene copolymer, silicone tree , Epoxy resin, melamine resin, polycarbonate resin, vinyl resin, silk powder, etc., red 104, red 106, red 227, red 228, yellow 4, yellow 5, yellow 202, yellow 203 No., Yellow 205, Yellow 401, Blue No. 1, Green No. 3, etc. Two or more kinds of powders and composites thereof may be used. Similarly, the shape and particle size of the powder are not particularly limited.

Examples of the surface treatment agent include fluorine-containing compounds such as perfluoroalkyl phosphate ester, perfluoropolyether silane, perfluoroalkyl silane, perfluoropolyether-modified polyurethane, perfluoroalkyl-modified silicone, and perfluoropolyether-modified silicone. And organopolysiloxanes such as silicone and modified products thereof, alkylsilanes, organic titanates, polyolefins, hydrogenated lecithins, acylated amino acids, ester oils, fatty acids, metal soaps, and the like. These powders are preliminarily made of at least one oxide or hydroxide such as aluminum, magnesium and titanium in order to increase the affinity with the fluorine-containing copolymer and perform a more optimal surface treatment. It may be coated. Furthermore, these powders may be plasma-treated.

  One or more kinds of the above-mentioned treated powder can be blended in the solid powder cosmetic, and if it is contained in the composition in an amount of 5 to 40% by weight, the entire face that has not been obtained with the conventional surface-treated powder is brightened. It is possible to further enhance the youthful impression that has been lifted up, and the effect lasts and is excellent for makeup. In other words, it does not impair the feeling of gloss, is resistant to sweat and sebum, and has an excellent moisturizing effect. It is preferable because it can bring out characteristics that are strong against breakage caused by drying.

  The oily component in a paste form at 25 ° C. used in the present invention is a semi-solid oily component having a high viscosity at 25 ° C., and is a general test described in Quasi-Drug Raw Material Standard 2006 (published by Yakuji Nippo).

Moreover, these can use 1 type (s) or 2 or more types as needed.

  The oil component is preferably contained in an amount of 0.1 to 2.0% by weight in the composition of the solid powder cosmetic. Within this range, when the pearl pigment is added together with the composite powder coated with spherical organic powder and the treated powder of the fluorinated copolymer, the makeup and moisturizing effects are good while enhancing the youthful impression of lift. A solid powder cosmetic can be obtained.

  In addition, the basic knowledge regarding the blending of the treated powder of the fluorinated copolymer and the paste-like oily component into the solid powder cosmetic is shown in Japanese Patent Application No. 2009-296460. In the present invention, this knowledge is applied to a composite powder obtained by coating a pearl pigment with a spherical organic powder, so that in general, a fluorine-containing compound having a perfluoroalkyl group has low reflectivity. Furthermore, the characteristics of the composite powder that creates a three-dimensional effect are further extracted, and it is bright and three-dimensional over time while preventing sweat, sebum, and makeup loss due to dryness, and the face is lifted up to show youthfulness. The makeup effect is further enhanced.

  The solid powder cosmetic of the present invention can contain potassium aluminum sulfate dodecahydrate (sulfuric acid (AL / K)) and / or sodium chloride. When sulfuric acid (AL / K) and sodium chloride were blended in the solid powder cosmetic of the present invention, there was an effect of suppressing makeup slippage due to sweating. Moreover, these can use 1 type or 2 types as needed.

  The sulfuric acid (AL / K) and sodium chloride component are preferably contained in a total amount of 0.05 to 0.5% by weight in the composition of the solid powder cosmetic. Within this range, when combined with a composite powder obtained by coating a pearl pigment with a spherical organic powder, a treated powder of a fluorinated copolymer, and a paste-like oily component, the youthful impression that is even more shiny and lifted up. To obtain an excellent solid powder cosmetic that has a function that can be seen on the face of the face, prevents makeup from breaking without impairing its gloss, and does not break down due to drying even in a well-worked environment such as an air conditioner in summer. Can do.

  Although this invention is solid powder cosmetics containing the above-mentioned component, specifically, cosmetics, such as a powder foundation, a cheek color, and an eye shadow.

  The solid powder cosmetic of the present invention can be prepared according to a usual method. Further, the solid powder cosmetic of the present invention includes, in addition to the above-described constituents, water, fats and oils, which are components blended in ordinary cosmetics, as long as the effects of the present invention are not impaired as necessary. , Hydrocarbons, fatty acids, alcohols, alkyl glyceryl ethers, esters, silicone oils, fluorine oils, polyhydric alcohols, sugars, polymers, surfactants, moisturizers, UV absorbers, chelating agents, pH adjusters, antioxidants Agents, bactericides / preservatives, dyes, fragrances, pigments, plasticizers, organic solvents, drugs, animal and plant extracts, pearl pigments, surface treatment powders, composite pigments, amino acids and peptides, vitamins, etc. However, it is not particularly limited to these.

  Even when a fluorine-containing compound having a perfluoroalkyl group, which is generally said to have low reflection characteristics, is used for the solid powder cosmetic of the present invention, the convex part of the face is brightened while brightening the entire face. It was clarified that the youthful impression that was brightened and lifted up was obtained, and that the angle dependency of the reflected light was higher than when the conventional surface-treated powder was combined. In addition, the composite powder in which the blended pearl pigment is coated with the spherical organic powder is a powder that suppresses the diffused light and enhances the regular reflection. Therefore, this composite concept is a method for limiting the direction of light reflection. It can also be used in other fields. Furthermore, this solid powder cosmetic has a good makeup and moisturizing effect due to the fluorine-containing copolymer used in the present invention in particular. When the cosmetic is applied, makeup by sweat or sebum At the same time, the effect of preventing the skin from being dried by the outside air and enhancing the moist feeling of the skin, and the effect of preventing the makeup from slipping off the cosmetic film from the skin and the dusting are improved.

  Next, for better understanding of the present invention, the present invention will be described in more detail with reference to production examples and examples, but the present invention is not limited thereto.

  The example of the composite powder which coat | covered the pearl pigment used for this invention with spherical organic powder is shown.

Composite powder 1 (2.5 wt% 300 nm methyl methacrylate crosspolymer / particle diameter 5.0-25.0 μm pearl pigment)
0.01 g of sodium lauryl sulfate was dissolved in 450 g of ion-exchanged water, and 1.25 g of methyl methacrylate crosspolymer, which is a spherical organic powder having an average particle diameter of 300 nm, was ultrasonically dispersed for about 5 minutes. Thereafter, 48.75 g of pearl pigment (TIMIRON SUPERSHEEN MP-1001 manufactured by Merck & Co., Ltd., thickness 0.15 to 0.30 μm, measured with an electron microscope) was added and ultrasonically dispersed for about 5 minutes, and then stirred with a magnetic stirrer. An appropriate amount of a commercially available polyaluminum chloride aqueous solution was added, and stirring was further continued for about 10 minutes, followed by filtration and water washing, followed by drying to obtain a composite powder. (Note that the methyl methacrylate crosspolymer, which is a spherical organic powder having an average particle diameter of 300 nm used here, is displayed as 0.3 μm in the catalog.

  As described above, it was confirmed that the face of the powder foundations of the prescription examples 1 and 2 was lifted up to give a youthful impression. When the powder foundation, which is a solid powder cosmetic of the present invention, is applied, the convex part of the face overflows with glossiness, and the part around the face looks relatively dark. I was able to produce. In addition, although the result of the three-dimensional effect evaluation was favorable in both Formulation Examples 1 and 2, it was decided to use the composite powder 1 blended in Formulation Example 1, which was recognized to have a higher effect, for future studies.

(Solid powder cosmetic formulation)

(Preparation method)
Components (1) to (23) were uniformly mixed with a Henschel mixer, and pulverized with an atomizer. Further, the mixed pulverized product of components (1) to (23) and the components (24) to (27) that have been heated and mixed in advance are added to a Henschel mixer and mixed uniformly. After pulverizing the atomizer, the mixture is passed through a sieve. The powder foundation was obtained by pressing on an inner plate.

(Gloss measurement)
Make up the face, make the convex part of the face shine more brightly, and the part around the face looks relatively dark and the face does not appear to swell, making youthful impression that lifts up In order to ascertain whether it is a material, the reflection characteristics of light by gloss measurement were evaluated for the powder foundations of Formulation Example 1 and Comparative Examples 2 to 4 prepared. The evaluation was performed by two methods: a method in which a sample was prepared using a chart paper and the measurement was performed, and a method in which the measurement was performed by applying a solid powder cosmetic on a pseudo skin sheet. As a method using a chart paper, first, a double-sided tape 40 mm width made by Nichiban Co., Ltd. was applied to the black part of OPERITY CHARTS made by LENETA, and each powder foundation was uniformly applied with a cosmetic cheek brush to prepare a measurement sample. The measurement sample was fixed at an incident angle of 45 degrees with a digital variable gloss meter manufactured by Suga Test Instruments Co., Ltd., and the gloss intensity at each light receiving angle was measured. As a method using a pseudo skin sheet, each powder foundation was uniformly applied to a BIO SKIN PLATE manufactured by BEAULAX with a cosmetic puff, and the gloss intensity at each light receiving angle was measured in the same procedure as the gloss measurement using chart paper.

In the present invention, the composite powder obtained by coating the pearl pigment with the spherical organic powder, the FA-treated powder, and the oily component in paste form are combined and blended to enhance the angle dependency of the reflected light and produce a stereoscopic effect. That is, the intensity of the light reflected from an angle deviating from the 45 degree angle that is regularly reflected with respect to the incident angle of 45 degrees is relatively lowered. In other words, the base is changed from the shape of the mountain-like reflection curve. If it is a solid powder cosmetic that has a reflection curve with a drooping shape, the contrast of the light in the regular reflection region and the region outside the regular reflection will increase, and the three-dimensional effect can be emphasized and lifted up. I thought that I could produce it. Therefore, in order to determine that the angle dependency of the reflected light has increased, the ratio (I _max ) of the maximum value (I _max ) of the gloss intensity measured by the method described above and the reflection intensity (I ₀₅ ) at a light receiving angle of 5 degrees. / I ₀₅ ) was calculated and compared.

(Evaluation of three-dimensional feeling and lift-up feeling using dolls)
Further, these powder foundations were applied to a doll for makeup training, and evaluation was performed in the same procedure as the evaluation of the three-dimensional effect / lift-up feeling using the doll in Example 1.

As a result of these examinations, the characteristic features are summarized as follows.
Maximum gloss intensity I _max / I _{05 According to} monitor
Gloss determination prescription example 1 2.11 1.21 ○
Comparative Example 2 2.09 1.14 ×
Comparative Example 3 1.90 1.08 ×
Comparative Example 4 1.87 1.10 ×
Of the results here, the “maximum gloss intensity” on the left is the maximum gloss intensity obtained by gloss measurement using chart paper, and the next “I _max / I ₀₅ ” is a pseudo value. These are the values obtained by gloss measurement using a skin sheet.

As described above, Formulation Example 1 containing FA-treated powder shows the highest value of gloss intensity, the highest value of both I _max / I ₀₅ , specularly reflected light is bright, and gloss is highly angle dependent. I found out. Further, in Comparative Example 2 containing the PF-5-treated powder, the maximum value of the gloss strength was almost the same value as in Formulation Example 1, but I _max / I ₀₅ was a value lower than that in Formulation Example 1. The angle dependence of the reflected light was low. Comparative Examples 3 and 4 each containing untreated and silicone-treated powders had the maximum gloss intensity, I _max / I ₀₅ , both of which were lower than those of Formulation Example 1, and the brightness of specular reflection light. Both the angle dependences of reflected light were low. From these results, the specular reflection gloss intensity and the angle of the reflected light were obtained by blending the FA-treated powder with the composite powder coated with pearl pigment with spherical organic powder and the powder foundation containing the pasty oil component. It became clear that the dependency was further increased. This time, in order to compare with the FA-treated powder, we prepared and evaluated the same amount of PF-5 treated, silicone-treated and untreated powder, respectively. It was found that the angle dependency was enhanced most effectively and the glossiness was enhanced.

  Next, in order to examine the lift-up effect and makeup feeling when the powder foundation of the present invention is actually applied to a human face, a powder foundation is prepared according to the formulation shown in Table 3 below and the manufacturing method shown below. Evaluation was performed according to an evaluation method and a criterion, and the results are shown in Table 3.

(Sustained evaluation of three-dimensional feeling and lift-up feeling)
Furthermore, in the above-mentioned skin moisturizing test for sebum and sweat and the cosmetic moisturizing test for dryness, if the skin shines due to sweat or sebum, the reflection of light by the shine spreads over the entire face, and the three-dimensionality of the face is lost or dry. It was well anticipated that the glossiness itself was lost due to the peeling of the decorative coating film due to, or that the roughness of the coating film appeared and the light reflected from the skin diffused. Therefore, at the time when 3 hours passed each, the duration of the three-dimensional effect / lift-up feeling of the face was also evaluated just in case. Good only when 8 or more out of 10 panelists judge that “three-dimensional effect / lift-up feeling persists” under both test conditions of makeup test for sebum and sweat and makeup test for dryness ( ○).

  As is clear from the results in Table 3, the powder foundations of Formulation Example 1 and Formulation Examples 3 to 14 of the present invention have a higher three-dimensional effect and lift-up feeling immediately after application than Comparative Examples 5 and 6, and sebum. It had excellent makeup for sweat and makeup for dryness. Moreover, in the prescription example 1 and the prescription examples 3-14, it has confirmed that it was excellent also in the persistence of the three-dimensional effect and lift-up feeling after 3 hours progress.

  First, when the finish immediately after the makeup was examined, the prescription examples 1, 3, 4, and 6 of the present invention had a high effect of being three-dimensional and appearing to be lifted up. Compared with Formulation Examples 1, 3, 4, and 6, Formulation Example 5 containing 5% by weight of FA1-treated sericite (5%) tended to have a slightly lower steric effect, which is high. In order to show the lift-up effect, it was determined that it is preferable to blend 5% by weight or more of the FA-treated powder. In addition, each of Formulation Example 1 and Formulation Examples 3 to 6 containing 5 to 40% by weight of FA-treated powder has sufficient makeup for sweat and sebum, and the three-dimensional effect after 3 hours has elapsed since application. The lifted-up view was maintained without any damage. On the other hand, Comparative Example 6 containing no FA-treated powder had insufficient makeup for sweat and sebum. Therefore, it is considered preferable to add 5 to 40% by weight of the FA-treated powder in the formulation in order to prevent makeup slippage due to sweat and sebum while maintaining a high lift-up effect and to maintain a three-dimensional feeling.

  As shown in Formulation Example 1 and Formulation Examples 7 and 8, a foundation containing 0.1 to 2.0% by weight of a paste-like oily component has a youthful finish with a three-dimensional effect, and is based on sweat and sebum The makeup against dryness was good while preventing makeup loss, and the three-dimensional effect after 3 hours and the lifted-up appearance remained intact. On the other hand, although the formulation example 9 containing 3.0% by weight of a paste-like oily component tended to have a slightly lowering of makeup against sweat and sebum, the three-dimensional effect and lifted up immediately after makeup and after 3 hours had passed. There was no problem with how it looks. Comparative Example 5 and Comparative Example 6 that do not contain a paste-like oily component do not have sufficient moisturizing effect, and makeup loss due to drying is observed. In particular, Comparative Example 6 that does not contain FA-treated sericite has a three-dimensional effect and lift-up. There was a strong tendency to lower the appearance.

  As seen from Formulation Example 1 and Formulation Examples 10-14, Formulation Example 1 containing 0.1% by weight of sodium chloride compared to Formulation Example 9 that does not contain sodium chloride or sulfuric acid (AL / K) is more sweaty.・ As the makeup for sebum has improved, the usefulness of containing sodium chloride and sulfuric acid (AL / K) in the cosmetic is clear (three-dimensional effect after 3 hours and the appearance of lift-up) The difference was not clear.) Moreover, the formulation examples 11-14 which contain 0.05-0.5 weight% of sodium chloride and / or a sulfuric acid (AL / K) have good makeup for sweat and sebum, and makeup for dryness, Immediately after makeup and after 3 hours, the three-dimensional effect and the lifted appearance were very good. Therefore, it is more preferable that sodium chloride or sulfuric acid (AL / K) is blended in the cosmetic material in an amount of 0.05 to 0.5% by weight.
