Description

The present invention relates to make-up cosmetics. The present invention specifically relates to a make-up cosmetic that makes skin defects such as age spots, pores, and dullness inconspicuous and gives a transparent feeling to the skin, enabling a natural finish and sustaining the cosmetic effect. Regarding make-up cosmetics with excellent sex.

Makeup cosmetics such as foundations and concealers have the effect of correcting skin color and unevenness in areas with skin defects such as age spots, pores, and dullness, and making them inconspicuous. In recent years, there has been a demand for make-up cosmetics that give a transparent feeling to the skin while hiding the defects of the skin, enable a natural finish, and can maintain such a makeup effect for a longer period of time. ..

Makeup cosmetics generally contain a large amount of a coloring pigment having a high refractive index such as titanium dioxide or iron oxide in order to improve the hiding power. However, in such a make-up cosmetic, the cosmetic film formed on the skin surface becomes a "mat", and it may be difficult to obtain a cosmetic film having a transparent feeling and a natural luster.

On the other hand, the make-up cosmetic may contain a pearl pigment such as mica titanium oxide coated on mica in order to give the skin a beautiful appearance and a glossy feeling at the time of application. This pearl pigment is preferably used because it can obtain various color tones depending on the film thickness of titanium oxide coated on the mica surface and gives a glossy feeling. However, mica titanium has a high glossiness but a low saturation of interference light.

As a method for improving the characteristic of mica titanium, which has low saturation of interference light, for example, Patent Document 1 proposes mica titanium coated with a red organic dye, and by applying a foundation containing this, a foundation containing the mica titanium is proposed. It is described to restore a natural and healthy skin color without dullness.

Japanese Unexamined Patent Publication No. 2004-315426

However, in the cosmetics using the method of Patent Document 1, if the amount of titanium dioxide having a high refractive index blended with the organic dye-coated mica titanium is increased, the glossiness of the organic dye-coated mica titanium may be hidden. .. In addition, if the amount of organic dye-coated mica titanium is increased in accordance with the amount of titanium dioxide, the organic dye of organic dye-coated mica titanium in the decorative film formed on the skin surface is affected by sebum and the like over time and becomes dull red. This phenomenon may occur, and it may be difficult to maintain the cosmetic effect immediately after application. Furthermore, when organic dye-coated mica titanium is used in emulsified cosmetics, it also affects the storage stability. For example, if the amount of powder such as titanium dioxide or organic pigment-coated mica titanium in the emulsified cosmetic is increased, the dispersibility of the powder may deteriorate or it may be difficult to secure long-term storage stability. was there.

In make-up cosmetics, in order to improve the covering power (concealing power) for correcting skin defects, it is necessary to add a large amount of pigment-grade titanium dioxide having a high refractive index. In this case, even if mica titanium is further added in order to make the skin after application a natural and healthy skin color, the glossiness of mica titanium may be hidden by the pigment grade titanium dioxide. As described above, it has been difficult to develop a cosmetic that gives a transparent feeling and gives a natural finish while having an excellent effect of correcting skin color and unevenness due to skin defects.

An object of the present invention is to give a transparent feeling to the skin, enable a natural finish, and to maintain such a cosmetic effect for a longer period of time, while hiding skin defects such as age spots, pores, and dullness. It is to provide various make-up cosmetics.

That is, the present invention is a make-up cosmetic, in which one or more pearl pigments having an average particle size of component (A) of 1.0 to 15.0 μm and exhibiting an orange or red interfering color and components. (B) Contains fine particle metal oxide having an average primary particle size in the range of 0.05 μm to 0.12 μm.

The component (A) is preferably a pearl pigment having a hydrophobic surface.

The component (B) is preferably selected from fine particle titanium dioxide, fine particle zinc oxide, or a combination thereof.

It is preferable that the component (A) is 0.5 to 10.0% by mass and the component (B) is 1.0 to 15.0% by mass based on the total mass of the makeup cosmetics.

The make-up cosmetic is preferably a foundation, a makeup base, or a concealer.

According to the make-up cosmetic according to the present invention, it is possible to give a transparent feeling to the skin while hiding the defects of the skin such as spots, pores and dullness, and to enable a natural finish. The transparency is usually achieved by allowing light to pass through the skin and be emitted via internal scattering, and is in a state where there is no matte feeling (thick coating feeling). Conventionally, it has been difficult to achieve both the covering power of skin defects and the transparency, but according to the makeup cosmetic according to the present invention, the average particle size of the pearl pigment is 1.0 to 15. The light characteristics are effective by using a 0.0 μm orange or red interfering color and using a fine particle metal oxide having an average primary particle diameter in the range of 0.05 μm to 0.12 μm. It is possible to achieve both covering power and transparency by controlling the particles, and it is possible to maintain the above-mentioned cosmetic effect for a longer period of time.

The evaluation results of the spectral reflectance in the visible light region (400 to 700 nm) of the make-up cosmetics of Examples 1 to 5 according to the present invention are shown. The evaluation results of the spectral reflectance in the visible light region (400 to 700 nm) of the make-up cosmetics of Example 1 and Comparative Examples 1 to 6 according to the present invention are shown.

Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to the embodiments described below. According to one embodiment of the present invention, the make-up cosmetic contains at least the component (A) and the component (B).

[Component (A)]
The component (A) is one or more pearl pigments having an average particle size of 1.0 to 15.0 μm and exhibiting an orange to red interference color. The pearl pigment is a powdery pigment having a pearly luster and a metallic appearance. Examples of the pearl pigment include, for example, mica titanium, bismuth oxychloride, fish scale foil and the like, and mica titanium is particularly preferable. Mica titanium is a surface of mica formed into smooth flaky particles coated with a layer of titanium oxide. Examples of mica include muscovite, biotite, phlogopite, and synthetic phlogopite. Further, instead of mica, a pearl pigment containing glass powder, aluminum, talc, silica or the like as a mother powder may be used. Further, the coating layer on the surface of the mica or mother powder was coated with iron oxide instead of titanium oxide, and the coating layer of titanium oxide or the like on the surface of the mica or mother powder was further coated with iron oxide or the like. It may also be used as a pearl pigment. As described above, the pearl pigment used as the component (A) is an interference pearl pigment which is made to exhibit a predetermined interference color with titanium oxide or the like, and does not include the pearl pigment coated with the pigment.

The pearl pigment used as the component (A) has an average particle size in the range of 1.0 to 15.0 μm, more preferably 5.0 to 10.0 μm. If the average particle size is smaller than 1.0 μm, it is difficult to exhibit a predetermined interference color, and when applied to the skin surface as a make-up cosmetic, the skin feels slippery or taut. When the average particle size is larger than 15 μm, the brightness of the pearl pigment becomes high, a feeling of spotting occurs, the decorative film has an unnatural finish, and the unevenness of the skin becomes conspicuous. Here, the average particle size is obtained as a particle size corresponding to an integrated value of 50% in the particle size distribution measured by the laser diffraction method.

The pearl pigment used as the component (A) exhibits an interference color of orange or red. The interference color of the pearl pigment is the color of the reflected light (interference light) reflected from the pearl pigment, and may be a color in which the appearance of the pearl pigment is visually confirmed. In the case of mica titanium, for example, the color of the interference color changes depending on the thickness of the coating layer such as titanium oxide. The thickness of the coating layer of titanium oxide is not particularly limited as long as an interference color of orange to red can be obtained, and may be appropriately selected in the range of, for example, 10 to 1000 nm. The orange to red interference color is, for example, the color of the reflected light having a wavelength of 580 to 780 nm.

The pearl pigment used as the component (A) preferably has a particularly high reflectance in the spectral reflection spectrum in the wavelength region of 580 nm to 780 nm. Specifically, the reflectance for visible light having a wavelength of 570 nm to 780 nm is preferably 20% or more, more preferably 40% or more, and the reflectance for visible light having a wavelength of 610 nm to 780 nm is preferably 25%. Above, more preferably 45% or more. The change in reflectance of the pearl pigment used as the component (A) in the visible light region (380 nm to 780 nm) can be represented by a spectral reflectance curve. This spectral reflectance curve includes one recess where the reflectance is the minimum value in a predetermined wavelength region, the reflectance increases from the recess toward the short wavelength side, and reflection is performed from the recess toward the long wavelength side. It is preferable that the rate increases. For example, the spectral reflectance curve in the wavelength range of 460 to 480 nm or 500 to 520 nm may have recesses having a reflectance of 25% or less or 15% or less. For example, when the recess is in the wavelength region of 460 to 480 nm, the reflectance in the wavelength region of 380 to 460 nm and 480 to 580 nm is preferably in the range of 25 to 40%. For example, when the recess is in the wavelength region of 500 to 520 nm, the reflectance in the wavelength region of 380 to 460 nm is preferably in the range of 20 to 35%, and in the wavelength region of 460 to 500 nm and 520 to 580 nm. The reflectance is preferably in the range of 15 to 20%. The reflectance is measured in the visible light region by a spectrophotometer using, for example, a sample prepared by applying a pearl pigment used as the component (A) on a black artificial leather at a concentration of 1 mg / cm ² . The spectral reflectance at (380 nm to 780 nm) may be measured. Further, the pearl pigment used as the component (A) preferably has a brightness (L ^* value) of 40 to 80 based on the L ^* a ^* b ^* color system. The brightness (L ^* value) may be measured by a color difference meter using, for example, a sample prepared by applying the lightness (L ^* value) on black artificial leather so as to be 1 mg / cm ^{2 in the same} manner as described above. ..

As the pearl pigment used in the present invention, a commercially available product may be used as it is. Specific commercial product names that can be used as the pearl pigment used in the present invention include "Lonaflare Balance Red", "Timilon Silk Red" (manufactured by Merck), "Flamenco Silk Red", and "Flamenco Silk Orange".

A treated powder composed of a pearl pigment and a silicone compound such as methylhydrogenpolysiloxane or dimethylpolysiloxane (the amount of the silicone compound with respect to the pearl pigment is preferably 0.1 to 20% by mass), for example, the silicone compound. After dissolving in an amount of isopropanol or hexane in an amount of 0.3 to 50% by mass, the mixture is obtained by stirring at room temperature using, for example, a Henschel mixer. Next, the mixture was placed in a dryer at 100 ° C. to evaporate the solvent and pulverized, and then the powder was placed in an electric furnace set at 260 to 500 ° C. in advance and heated for 1 to 24 hours. It may be a silicone-treated powder.

The type of the fine particle metal oxide is not particularly limited as long as it is a metal oxide that can be blended in makeup cosmetics. Examples of metal oxides include titanium dioxide, zinc oxide, zirconium oxide, cerium oxide and the like. For the purpose of suppressing the catalytic activity, a fine metal oxide obtained by coating the surface of these metal oxides with an inorganic compound such as silica or alumina may be used. Further, the fine particle metal oxide preferably contains at least one selected from the group consisting of fine particle titanium dioxide and fine particle zinc oxide from the viewpoint of excellent ultraviolet protection effect.

The fine particle metal oxide used as the component (B) has an average primary particle diameter in the range of 0.05 μm to 0.12 μm. When the average primary particle size is smaller than 0.05 μm, the transparency is high and the hiding power is low, so that it becomes difficult to cover the defects of the skin when applied to the skin surface. When the average primary particle size is larger than 0.12 μm, the hiding power is high, but the transmittance of visible light is low, so that it is difficult to obtain a transparent finish when applied to the skin surface. Here, the average primary particle size is a number average particle size of the primary particle size measured by observation with a scanning electron microscope. Fine particle metal oxides having an average primary particle diameter in the range of 0.05 μm to 0.12 μm have the property of easily transmitting light on the long wavelength side while controlling the short wavelength side in the visible light region. It is suitable for the effect of covering only the defects of the skin without hiding the reflected light of orange to red, which is the interference light of the pearl pigment of the component (A).

The shape of the fine particle metal oxide may be spherical, substantially spherical, indefinite, spindle-shaped, rod-shaped, needle-shaped, strip-shaped, plate-shaped, or the like, but is not particularly limited. As the fine particle metal oxide used in the present invention, either one that behaves as primary particles when blended in make-up cosmetics or one that behaves as aggregated particles after being granulated can be used.

The fine particle metal oxide used in the present invention is not particularly limited, but one that has been hydrophobized may be used. For example, the fine particle metal oxide whose surface is not hydrophobized at the time of acquisition may be hydrophobized in the process of producing cosmetics. Hydrophobic treatment methods include silicone treatment with methylpolysiloxane, fluorine treatment with perfluoroalkyl phosphate, amino acid treatment with N-acylglutamic acid, lecithin treatment, metal soap treatment, fatty acid treatment, and alkyl phosphorus.

For example, examples of the fine particle zinc oxide include "MZ-200" and "MZY-203S". , "MZY-210M3S", "MZ-150", "MZ-153S" (all manufactured by TAYCA Corporation), and one or two or more of these can be used.

The content of the fine particle metal oxide of the component (B) is preferably 1.0 to 15.0% by mass, more preferably 2.0 to 10.0% by mass, based on the total mass of the make-up cosmetics. %, More preferably 3.0 to 6.0% by mass. If the content is less than 1.0% by mass, the effect of covering the defects of the skin may not be obtained when applied to the skin surface. If the content exceeds 15.0% by mass, the effect corresponding to the increase in the content may not be obtained, and formulation may be difficult.

Further, the fine particle metal oxide may be blended by carrying each or two kinds of plate-shaped powder or spherical powder to be blended in general cosmetics and performing a treatment such as compounding.

The make-up cosmetic according to the present invention may contain additional powder components in addition to the above essential components (A) and (B).

For example, titanium oxide that does not satisfy the particle size characteristics of the component (B) can also be used as a powder component for the purpose of a hiding agent. As such titanium oxide, for example, pigment-grade titanium dioxide having an average primary particle size of 0.2 to 0.3 μm can be used. When the pigment grade titanium dioxide is highly blended, the correction power for skin defects is high, but the transmittance of light on the long wavelength side in the visible light region is low, so the reflection of pearl pigments exhibiting an interference color of orange to red. Light is also blocked, and the effect of the present invention may not be sufficiently obtained. Therefore, it is preferable that the content of pigment-grade titanium dioxide is 10.0% or less, or that pigment-grade titanium dioxide is not blended, based on the total amount of makeup cosmetics.

The use of the make-up cosmetic according to the present invention is not particularly limited, but the effect of the invention can be easily exerted in sunscreen cosmetics in addition to foundations, makeup bases, concealers, blushers, lipsticks, etc. Can be done. For example, the dosage form of the foundation may be, for example, loose foundation (white powder), cake-like powder foundation, W / O emulsified liquid foundation, oil-based stick foundation, etc., and the makeup base may be W / O emulsified makeup. It may be a foundation or an O / W emulsified makeup foundation, and gives an effect of achieving both a concealing effect and a transparent feeling of the skin in any formulation. Among them, an emulsified cosmetic is mentioned as a particularly preferable dosage form of the make-up cosmetic according to the present invention.

The make-up cosmetic according to the present invention is a mixture of the components usually blended in the make-up cosmetic and the above-mentioned components, and the method for producing them is not particularly limited and is prepared by a conventional method.

For example, when the make-up cosmetic is a water-in-oil emulsified foundation, the oil phase is first formed. For example, after mixing two or more kinds of oil components and two or more kinds of emulsifiers, the mixture is heated to 70 to 80 ° C. and stirred (for example, 1000 to 2000 rpm for 5 to 10 minutes) to make it uniform. Oil phase can be formed. At least two or more kinds of oil components and emulsifiers can be selected from the above-mentioned components. In addition to the oil component and the emulsifier, a film-forming agent, an ultraviolet absorber, and a medicinal component may be added at the time of mixing. Next, an aqueous phase is formed. For example, by mixing water, two or more kinds of polyhydric alcohols, a preservative or an antibacterial agent, and then heating at 70 to 80 ° C., an aqueous phase in which other components are dissolved in water can be formed. The polyhydric alcohol and the preservative or antibacterial agent can each be selected from the above-mentioned components. In addition to water, polyhydric alcohols and preservatives or antibacterial agents, when mixed, moisturizers, sugars, sequestrants, polymer thickeners such as water-soluble polymers, lower alcohols, film-forming agents, medium Japanese agents, pH adjusters, and medicinal ingredients may be added. Next, a powder mixture containing at least the component (A) and the component (B) is obtained. For example, the component (A), the component (B), and two or more powder components are mixed to obtain a mixture uniformly dispersed by, for example, a Henschel mixer. In addition to the component (A) and the component (B), pigment grade titanium dioxide and two or more other powder components may be added. The powder mixture is then added to the oil phase. For example, by adding the above-mentioned powder mixture to the oil phase and stirring (for example, 3000 to 4000 rpm, 5 to 10 minutes), an oil phase in which the powder is uniformly dispersed can be obtained. Next, the aqueous phase is added to the oil phase containing the powder. For example, the aqueous phase may be slowly added little by little to the oil phase in which the above-mentioned powder is uniformly dispersed while being stirred (for example, 3000 to 4000 rpm). Next, the mixture of the oil phase and the aqueous phase containing the powder is stirred in a heated state. For example, a mixture of an oil phase and an aqueous phase containing the above-mentioned powder is stirred at high speed (for example, 5000 to 6000 rpm) using a homomixer while being heated to 70 to 80 ° C. Then, an emulsion may be obtained. The emulsion is then cooled. For example, ice or cold water may be used to cool the emulsion to 20-30 ° C. Next, the cooled emulsion is degassed. For example, a vacuum pump may be used to degas. The emulsion after degassing is a water-in-oil emulsified foundation. Finally, the degassed emulsion may be filled in the container.

When the make-up cosmetic is an oil-in-water emulsified makeup base or a water-in-oil emulsified concealer, it may be produced by the same method as the above-mentioned water-in-oil emulsified foundation.

When the make-up cosmetic is a cake-like powder foundation, the oil phase is added to the powder mixture without forming an aqueous phase, and stirred with a Hellshell mixer, for example (for example, 100 to 200 rpm, 1 to 10 minutes). Then, the powder is uniformly dispersed. The powder mixture after mixing the oil phase is passed through a sieve, for example a 60 mesh sieve. The powder that has passed through the sieve can be used as a powder foundation. The powder that has passed through the sieve may be filled in a gold plate and compression-molded to form a cake-like powder foundation.

When the make-up cosmetic is an oil-based stick-like foundation, the powder mixture is added to the oil phase without forming an aqueous phase, and the mixture is stirred (for example, 3000 to 4000 rpm) using, for example, a dispar stirrer. After 5 to 10 minutes) to obtain an oil phase in which the powder is uniformly dispersed, the powder may be filled in a mold, cooled to 0 to 20 ° C., and loaded into a container to form an oil-based stick-like foundation. ..

Next, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the makeup cosmetics according to the present invention are not limited to these Examples.

First, the components (1) to (8) were mixed, heated to 80 ° C., and stirred at 1000 rpm for 5 minutes using a Dispar stirrer to obtain a uniform oil phase. Next, the components (9) to (15) were mixed and heated to 80 ° C. to dissolve them by heating to obtain an aqueous phase. Next, the components (16) to (30) were mixed and uniformly dispersed with a Henschel mixer (FM-10 manufactured by Mitsui Mining Co., Ltd.). Then, it was added to the oil phase, and the mixture was stirred uniformly at 3000 rpm for 10 minutes using a dispar stirrer. Next, the aqueous phase was slowly added to the oil phase containing this powder in a stirred state. Next, the powder-containing oil phase to which the aqueous phase was added was emulsified and mixed by high-speed stirring (5000 rpm, 5 minutes) using a homomixer in a state of being heated to 80 ° C. Next, the emulsified mixture was cooled to 30 ° C. with ice and cold water, degassed using a vacuum pump, and filled in a container to obtain a water-in-oil emulsified foundation.

The water-in-oil emulsified foundations of Examples 1 to 5 and Comparative Examples 1 to 6 were applied to the faces of female subjects (30 to 50 years old) using a cosmetic sponge, and the finish at the time of application was self-evaluated.

The above-mentioned A component, silicone-treated flamenco silk red and silicone-treated flamenco silk orange, and the comparative product of component A, silicone-treated flamenco silk violet, are all made by applying silicone treatment to a pearl pigment manufactured by BASF. It is a thing. The silicone treatment was carried out as follows. First, 490 g of a pearl pigment and 10 g of methylhydrogenpolysiloxane (trade name: KF-9901: manufactured by Shin-Etsu Chemical Co., Ltd.) were dissolved in 50 ml of isopropanol, then placed in a Henschel mixer and stirred at room temperature to obtain a mixture. The mixture was then placed in a dryer at 100 ° C. to evaporate the solvent and pulverize it. Next, the obtained powder was placed in an electric furnace set in advance at 400 ° C. and heated for 3 hours to obtain a silicone-treated powder.

From the results of Tables 1 and 2, the water-in-oil emulsified foundations of Examples 1 to 5, which are the makeup cosmetics of the present invention, "hide stains and pores" and "transparent and natural finish". It was an excellent make-up cosmetic for all items of "is" and "sustainability of makeup effect".

On the other hand, Comparative Example 1 which does not contain the component (A) or Comparative Examples 2 and 3 using the comparative product of the component (A) do not have a sufficient effect of hiding stains and pores, and a transparent and natural finish is obtained. I couldn't. Further, Comparative Example 4 containing no component (B) or Comparative Examples 5 and 6 using the comparative product of the component (B) did not have a sufficient effect of hiding stains and pores. And, in all of Comparative Examples 1 to 6, the persistence of the cosmetic effect was not sufficient.

[Evaluation of spectral reflectance]
Next, the make-up cosmetics of Examples 1 to 5 and Comparative Examples 1 to 6 were each applied to black artificial leather at a rate of 1 mg / cm ² to prepare a sample for spectroscopic measurement. Using this sample, the reflectance in the visible light region (400 nm to 700 nm) was measured using a spectrocolorimeter (manufactured by Nippon Denshoku Kogyo Co., Ltd., model number SD5000). The results of Examples 1 to 5 are shown in FIG. 1, and the results of Examples 1 and Comparative Examples 1 to 6 are shown in FIG. Since the reflectances of Examples 1 to 5 were high on the long wavelength side (580 nm to 700 nm), it is considered that the skin color correction effect was sufficiently obtained. In Example 1, the reflectance was higher in the measured wavelength region than in Comparative Examples 1 and 3 to 6, and the reflectance was particularly high in the wavelength range of 580 to 700 nm. From this, it is considered that the skin color correction effect was sufficiently obtained. In Comparative Example 2, since the red pigment-coated pearl pigment was used as the component (A), the reflectance on the long wavelength side was high, but the reflectance was higher than that in Example 1 in the wavelength region other than the long wavelength. It was low, and as mentioned above, the sustainability of the cosmetic effect was insufficient.
