Description

The present invention relates to cosmetics containing a combination of specific powders.

In recent years, base makeup has come to require not only the ability to hide skin imperfections such as age spots and freckles, but also to create a translucent, natural finish. In order to meet this demand, various proposals have been made regarding powders to be incorporated into base makeup cosmetics such as powder foundations.

Patent Document 1 describes a spherical powder having a core with different refractive indexes and a plurality of coating layers laminated thereon, and a cosmetic containing the powder with high light transmittance has a natural It is stated that a good finish can be obtained.

It is stated that the finish does not feel thick.

Patent No. 3605118 Patent No. 4044210

In recent years, people have begun to prefer not just a natural finish, but a natural yet moisturized glow, and there is a need for cosmetics that can achieve such a finish. Pearl pigments, which have traditionally been used to give skin a shine, give the skin an artificial glow, while oils give it a shiny feel, so they do not give a natural glow.
In view of this situation, an object of the present invention is to provide a cosmetic that provides a naturally moisturized and glossy finish.

As a result of intensive research, the present inventors have found that combining borosilicate glass powder with a spherical powder having a core having different refractive indexes and a plurality of coating layers laminated thereon increases light diffusion, and the above-mentioned problem can be solved. The inventors came up with the idea that this problem could be solved and completed the present invention.

That is, the present invention is as follows.
[1] A cosmetic containing the following components A and B.
A: (a) A coating layer made of a substance with a higher refractive index than (a), and (c) a coating layer made of a substance with a lower refractive index than (b) are laminated in order on the base material. B: Borosilicate glass powder which may be surface-treated [2] In component A,
(a) The refractive index of the base material is 1.3 to 1.8,
The refractive index of the substance (b) is 1.9 to 3.1,
The cosmetic according to [1], wherein the substance (c) has a refractive index of 1.3 to 1.8.
[3] In component A,
(a) the base material is silicic anhydride,
The substance (b) is titanium dioxide and/or zirconia,
The cosmetic according to [1] or [2], wherein the substance (c) is silicic anhydride.

[8] The cosmetic according to any one of [1] to [7], which is an oil gel type or an emulsifier type. [9] The cosmetic according to any one of [1] to [8], further comprising an ester oil.

By interspersing component B in the cosmetic film formed by the cosmetic composition of the present invention, the light transmittance increases uniformly over the entire application surface, thereby improving the light diffusion effect of component A. Therefore, a wide high-brightness region is applied to the application surface, giving the entire face a bright, moist and glossy look.

The shape of the (a) base material in the coated powder of component A is not particularly limited, and may be spherical, irregular, plate-like, or acicular, but it can diffuse light evenly. In order to transmit light, it is usually spherical (including approximately spherical).
(a) The particle size of the base material may be adjusted as appropriate depending on the desired particle size of the coated powder, the amount of coating in (b) and (c) described below, and the like. Although it depends on its shape, the particle size of the base material (a) is preferably 0.05 to 45 μm, more preferably 0.3 to 28 μm.

Examples of substances that have such a refractive index and can serve as the base material (a) include silicic anhydride (refractive index: approximately 1.54422), aluminum oxide (refractive index: approximately 1.76 to 1.77), and carbonic acid. Calcium (refractive index=approximately 1.6585) may be used, and silica is preferable from the viewpoint of transmittance.
As a commercially available product, Silica Microbeat P1500 (manufactured by JGC Catalysts & Chemicals Co., Ltd.) can be used as the base material.

The amount of (a) base material is preferably 45 to 90% by weight, more preferably 60 to 80% by weight, based on the entire coated powder of component A. When it is within this range, it is easy to prevent the coated powder from becoming whitish, and the cosmetic tends to have a natural finish.

The refractive index of the substance (b) in the coated powder of component A is higher than that of (a), preferably from 1.9 to 3.1, more preferably from 2.1 to 2.6.
Examples of substances that have such a refractive index and can become (b) include titanium dioxide (refractive index = approximately 2.493 to 2.586), zirconia (refractive index = approximately 2.13, 2.19, or 2. .20) etc. Titanium dioxide may be a rutile type crystal system, an anatase type crystal system, or a mixture thereof.

Substances that have such a refractive index and can become (c) include silicic anhydride (refractive index: approximately 1.54422), aluminum oxide (refractive index: approximately 1.76 to 1.77), and calcium carbonate (refractive index: approximately 1.54422), aluminum oxide (refractive index: approximately 1.76 to 1.77), 1.6585), and silica is preferred from the viewpoint of transmittance.

The amount of (c) is preferably 1 to 30% by weight, more preferably 2 to 10% by weight, based on the entire coated powder of component A. When it is within this range, it is easy to ensure brightness, and the cosmetics tend to have a natural finish due to the light diffusion effect.

The shape of the coated powder of component A is spherical (including approximately spherical).
The average particle diameter of the coated powder of component A is not particularly limited, but is preferably 0.1 to 50 μm, more preferably 0.4 to 30 μm. By being within this range, it is easy to handle when blended into cosmetics, and it tends to have a good feel when used.
Here, the average particle diameter is a value calculated by measuring the volume average of 30 arbitrary particles in an arbitrary field of view in a transmission electron micrograph.

The coated powder of component A is formed by laminating (a) a base material, (b) and (c) in this order, but may further contain other coating layers as long as the effect is not impaired. However, usually no other coating layer is included between (a) the base material and (b) and (c).
Examples of other coating layers include layers obtained by surface-treating the outside of the layer (c), such as dimethylpolysiloxane baking treatment, hydrogen methylpolysiloxane baking treatment, metal soap coating treatment, and perfluoroalkyl treatment. The layer may be formed by a hydrophobic treatment such as silane coupling treatment, silylation treatment, fatty acid coating treatment, coating treatment with acylamino acid and/or its salt.

The laminated powder in component A can be obtained by any method. For example, as described in Patent Documents 1 and 2, it can be produced by coating (a) a base material with (b) and (c) using a known method such as a sol-gel method or a spray drying method. can. Specifically, titanium hydroxide obtained by neutralizing a water-soluble titanium salt is precipitated on spherical silica in an aqueous carrier, and the fired product obtained by firing this is dispersed in a polar solution of water glass. It can also be produced by neutralizing water glass with an acid or the like, precipitating silica gel on the fired product, and sintering this. Another specific manufacturing method is to disperse spherical silica gel in an aqueous carrier, add titanium alkoxide to it, neutralize it with ammonia water, etc., precipitate titanium hydroxide on the spherical silica, and then sinter it. It can also be produced by dispersing this fired product in a polar solution of water glass, neutralizing it with an acid such as hydrochloric acid, washing it with water, and then firing it.
The coated powder of component A can be produced as described above, or a commercially available product can be used. Preferred examples of such commercial products include Multiple Beads (manufactured by JGC Catalysts & Chemicals), Multiple Beads II (manufactured by JGC Catalysts & Chemicals), and the like.

The average particle diameter of component B is preferably 5 to 60 μm, more preferably 8 to 50 μm, even more preferably 10 to 40 μm, particularly preferably 20 to 30 μm.
Further, the aspect ratio of component B is preferably 5 to 90, more preferably 10 to 80, even more preferably 20 to 70, particularly preferably 40 to 65.
Here, the average particle diameter is a value calculated by measuring the volume average of 30 arbitrary particles in an arbitrary field of view in a transmission electron micrograph. The arithmetic mean of the long and short diameters of the particles is considered to be the particle size.
Further, the aspect ratio is a value determined by calculating the average thickness by an arithmetic average of all the particles whose thickness can be read in the same field of view, and rounding off the average particle size/average thickness to the nearest whole number.

The surface treatment for component B may be a hydrophobic treatment or a hydrophilic treatment.

In the cosmetic composition of the present invention, since the light diffusion effect of component A is enhanced when used in combination with component B, it is possible to give a bright impression to the skin to which it is applied, and create a moist and glossy feeling. Therefore, it is suitable for base makeup cosmetics.
The dosage form of the cosmetic is not particularly limited, and includes, for example, a lotion dosage form, an emulsifier type such as a milky lotion or a cream (O/W type, W/O type, etc.), an oil dosage form, an oil gel dosage form, a gel dosage form. , powder formulation, etc. In the present invention, since components A and B exhibit high HAZE values even in a wet state, they are particularly suitable for oil gel type and emulsifier type.

EXAMPLES Hereinafter, the present invention will be explained in more detail with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist thereof.

<Reference example> Examination of the luminance range that creates a good glossy appearance Apply an appropriate amount of makeup base ("Pola Diem Couleur Primer LN", manufactured by Pola Co., Ltd.) to the inner arm of the subject, and apply the samples shown in Table 1 on top of it. The area to which an appropriate amount of the product was applied was photographed using a skin measurement device VISIA-Evolution (Canfield Scientific Inc.) in standard light photography mode. The obtained photographs were visually evaluated by 10 expert panelists. Further, a 500×500 pixel area was cut out from the obtained photograph, the brightness of each pixel in the area was measured, and a histogram for each brightness was created.

FIG. 1 shows a photograph of the inner arm to which each sample was applied and a histogram for each area of brightness.
Sample No. 1 was evaluated by panelists as having a moist and glossy finish. Looking at the brightness distribution, it was found that there is a certain amount of brightness region around 230 to 250 gradations.
Sample No. 2 was evaluated by panelists as having a matte finish. Looking at the brightness distribution, it was a uniform distribution with little variation.
Sample No. 3 was evaluated by panelists as having an unnatural finish with shine and glare. Looking at the luminance distribution, it was found that it is polarized, with a prominent number of luminance regions of 250 to 255 gradations.
Sample No. 4 was evaluated by panelists as having an artificially glittery finish. It was found that the brightness distribution was wide and there were many brightness regions of 250 to 255 gradations.

<Test Example 1> Effect of combination of spherical coating powder and borosilicate glass powder on diffused light and transmittance A high viscosity acrylic resin was spread on a slide glass with a 0.5 mil doctor blade (YOSHIMITSU SEIKI, JAPAN). Using a brush, each sample mixed with component a and component b shown in Table 1 was formed into a thin film, and triethylhexanoin (Myritol Gteh, manufactured by BASF Japan) was used to form a wet powder. The total transmittance (TT), diffused light ratio (HAZE), linear transmittance (PT), and diffused transmittance (Dif.) were measured using a camera (manufactured by Murakami Color Technology Research Institute).
The results are also shown in Table 1. When the diffusion coated powder (component A of the present invention) and methicone-coated borosilicate (Ca/Al) (component B of the present invention) are combined (sample Nos. 18 to 20), the transmittance is 90% or more. The HAZE value and diffused transmittance were also high. In particular, the HAZE value is higher than that of the diffusion-coated powder alone, and although the HAZE value of methicone-coated borosilicate (Ca/Al) alone is low, it is surprising that the HAZE value is improved by combining the two. there were.
In the combination of the diffusion coating powder and other powders, no improvement in both the HAZE value and the transmittance was observed.

<Test Example 2> Evaluation of finish and brightness when cosmetics are applied to the skin Oil gel type cosmetics (foundations) of Examples and Comparative Examples were prepared according to the formulations shown in Table 3 below. Specifically, component A in Table 1 was heated to 105 to 110°C, mixed with stirring, and adjusted to 85 to 90°C, and then component B was added and mixed with stirring to obtain a cosmetic.
An appropriate amount of the cosmetic of the example or comparative example was applied to the cheeks of the test subjects, and a photograph of the applied area was taken using a skin measurement device VISIA-Evolution (Canfield Scientific Inc.) in standard light photography mode. A 500×500 pixel area of the obtained photograph was cut out, the brightness of each pixel in the area was measured, and the number of pixels with brightness of 50 gradations (approximately 200 to 250 gradations) from the highest brightness was calculated.
FIG. 3 shows a high-brightness region (200 to 250 gradations) extracted from the photograph of the cheek area to which cosmetics have been applied (FIG. 2). FIG. 4 shows the number of pixels in the high brightness area in FIG. 3. The cosmetics of Examples gave a bright, moisturized and glossy finish to the entire cheeks, and a clear difference in finish from the cosmetics of Comparative Examples was observed.

The cosmetic of the present invention forms a cosmetic film with a lot of diffused light and a high total transmittance, so the entire application area is bright and produces a moist and glossy feeling. Therefore, the present invention meets consumer demand for excellent makeup effects and has high industrial applicability.
