Description

  The present invention relates to a makeup cosmetic that can change the skin hue sensation while having a transparent feeling, and gives a natural gloss with a fine and bright finish.

  Makeup cosmetics are required to change the texture of the skin by applying this, and the texture is controlled by using powders with strong diffuse reflection and powder with strong specular reflection. . For example, titanium oxide or spherical powder, which is a powder with strong diffuse reflection, is blended to obtain a matte finish, or plate-like powder with strong specular reflection such as mica, sericite, talc, etc. is blended to give a glossy finish. Or get. On the other hand, pigments with high hiding power such as titanium dioxide and iron oxide are blended in order to cover uneven color such as spots and freckles.

  However, when a pigment with high hiding power is used, there is a problem that the natural feeling is lost. On the other hand, when the texture is adjusted with a powder having a low hiding power, there is a problem that the covering power such as uneven color is lowered.

  In recent years, in order to solve these problems, it has been studied to change the skin hue sensation using a pearl pigment that has a strong hiding power and can control glossiness. For example, when titanium oxide-coated pearl pigment is used to give gloss, it can be given gloss by specular reflection in the specular reflection direction, but at an angle other than specular reflection, the powder itself has a whitish appearance. End up. Therefore, when cosmetics are applied over a wide area such as the entire face, the part facing the viewer has a glossy feeling, but the part that does not face the face tends to have a whitish texture, which tends to result in an unnatural finish. was there. In order to obtain a natural gloss, Patent Document 1 describes a powder in which a titanium mica surface is sequentially coated with alumina and silica. However, it is not possible to solve the whitish texture at the non-facing part.

On the other hand, for example, a pearl pigment coated with a colored metal oxide such as iron oxide is also commercially available. Patent Documents 2 and 3 propose a multilayer pearl pigment in which a plate-like powder coated with iron oxide is coated with a colorless metal oxide such as titanium oxide, but only a red pearl pigment can be obtained. It is not too much to express a bright and attractive texture.

  An object of the present invention is to provide a make-up cosmetic that can change the skin hue sensation while having a transparent feeling, and gives a natural gloss with a fine and bright finish.

  The present inventors provide a pearl pigment in which the surface of a flaky powder is coated with a colored metal or colored metal oxide having a controlled surface roughness, and further coated with a colorless metal or a colorless metal oxide, under specific conditions. Pearl pigments whose absolute value of a * and b * values of scattered light measured in (1) is 10 or less show a very vivid color, and if this pigment is used, the skin hue sensation can be changed while maintaining transparency. It was found that makeup cosmetics that give a natural gloss with a fine and bright finish can be obtained.

The present invention relates to a pearl pigment in which a surface of a flaky powder is coated with a colored metal or a colored metal oxide and further coated with a colorless metal or a colorless metal oxide, and the pearl pigment is coated on the surface of black artificial leather with an average of 0. Using a spectrocolorimeter with an S polarizing plate on the incident light side and a P polarizing plate on the light receiving side, applied at .05 mg / cm ² , the reflected light amount of the pearl pigment is measured under the 2 ° field of view with C light. When measured, the absolute value of the a * value and b * value of powder reflected light (scattered light) incident at 45 ° with respect to the normal direction of the measurement sample surface and received in the normal direction is 10 or less. A makeup cosmetic containing a pearl pigment is provided.
In the present invention, the a * value and b * value indicate chromaticity standardized by the International Commission on Illumination (1976) (CIE). Further, the method for measuring the a * value and b * value of the pearl pigment shown here (see FIG. 1) is referred to as “the method for measuring the a * value and b * value of the present invention”.

  The makeup cosmetics of the present invention can change the skin hue sensation while giving a clear feeling, and can give natural gloss with a fine and bright finish. Also, the feeling of use such as spreading during application is good.

  The flaky powder for obtaining the pearl pigment used in the present invention preferably has an average particle diameter of 2 to 200 μm and an average thickness of 0.01 to 5 μm. In particular, from the viewpoint of suitability for blending, it is more preferable that the average particle diameter is 2 to 20 μm and the average thickness is 0.05 to 1 μm. Here, an average particle diameter shows volume average particle diameter (D4) (average particle diameter calculated by the volume fraction). Measurement can be easily performed with a laser diffraction particle size distribution meter with good reproducibility. The thickness of the flaky powder is the average thickness obtained by measuring the difference from the reference surface with an atomic force microscope and arithmetically averaging it.

  Such flaky powders include mica, sericite, talc, kaolin, smectite clay mineral, synthetic mica, synthetic sericite, plate-like titanium dioxide, plate-like silica, plate-like aluminum oxide, boron nitride, barium sulfate, plate And titania-silica composite oxide. Of these, mica is particularly preferable in terms of surface smoothness.

  In the pearl pigment used in the present invention, examples of the colored metal covering the flaky powder include gold and copper, and gold is particularly preferable. Examples of the colored metal oxide include iron oxide, low-order titanium oxide, copper oxide, cobalt oxide, chromium oxide, nickel oxide and the like, and iron oxide is particularly preferable.

  Further, in the pearl pigment used in the present invention, examples of the colorless metal that covers the surface of the colored metal oxide include titanium, zirconium, zinc, tin, silicon, and aluminum, with titanium being particularly preferred. Examples of the colorless metal oxide include titanium oxide, zinc oxide, aluminum oxide and the like, and titanium oxide is particularly preferable.

The pearl pigment used in the present invention has an absolute value of 10 * or less of the a * value and b * value of powder reflected light (scattered light) when measured according to the “measurement method of a * value or b * value of the present invention”. , Preferably 5 or less.
A GCMS series manufactured by Murakami Color Research Laboratory Co., Ltd. can be used as a measuring machine capable of such colorimetry.

  Further, the pearl pigment used in the present invention is obtained by coating the surface of a flaky powder with a colored metal or a colored metal oxide. The surface roughness of the colored metal or the colored metal oxide is 10 nm or less, preferably 5 nm or less. Since the colored metal or the colored metal oxide has a characteristic of absorbing light of a specific wavelength, if the roughness of the coating surface is large, the scattering color becomes strong and the color of weak pearly luster is generated. By reducing the roughness of the coating surface, it is possible to obtain a pigment that suppresses light scattering and has a vivid color with little scattered light.

  In the present invention, the surface average roughness (Ra) indicates the centerline average roughness, and is 2 μm × 2 μm at a scan rate of 1.0 Hz using an atomic force microscope (Nanoscope III, manufactured by Digital Instruments). The average value when the range is measured is shown. At the time of measurement, the pearl pigment is dispersed in a solvent such as ethanol, adhered on a smooth substrate surface, adhered to the substrate by removing the solvent, and then measured with an atomic force microscope.

Further, in the pearl pigment used in the present invention, the optical film thickness of the colored metal or colored metal oxide coating layer is preferably 15 to 650 nm, particularly preferably 25 to 650 nm, and is preferably 250 nm or less, particularly 210 nm or less. preferable. If it exceeds 650 nm, the absolute thickness of the absorption layer increases, and the influence of light absorption becomes strong. Therefore, it is preferable to use a pearl pigment that takes advantage of the intrinsic color of a colored metal or colored metal oxide. For example, iron oxide is preferably a red pearl pigment when the optical film thickness exceeds 250 nm.
Here, the optical film thickness indicates a value obtained by multiplying the geometric layer thickness of a colored metal or colored metal oxide by a refractive index. For example, in the case of iron oxide (refractive index of 3.0), the geometric film thickness is preferably 8 to 220 nm, preferably 80 nm or less, and particularly preferably 50 nm or less. When the scattered light is sufficiently suppressed, for example, when iron oxide is used for the colored metal oxide, the interference light is gold when the optical film thickness is 120 to 210 nm, and the interference light is silver when the optical film thickness is 60 to 120 nm. is there. The geometric film thickness is measured by SEM.

Furthermore, when the surface of a colored metal or colored metal oxide is coated with a colorless metal or a colorless metal oxide to form a multilayer, pigments of various colors such as gold to green that are not bound to the color unique to iron oxide can be obtained. . The optical film thickness of the colorless metal or colorless metal oxide is preferably 180 to 900 nm on average. In the case of titanium oxide, the geometric film thickness is preferably 80 to 360 nm. If the scattering color is strong like the conventional pearl pigment, these interference lights are canceled out by the scattering color and cannot be observed with the naked eye, but the pearl pigment of the present invention suppresses the scattering color, so the coated colored Gold or green interference light that is not an intrinsic color of a metal or colored metal oxide can also be created.
When the optical film thickness of iron oxide or the like is large, it is advantageous when making red pigments unique to iron oxide. It becomes possible to make red.

Further, in the relationship of refractive index, when n _s <n> n _{0 in} the relationship between the flaky powder n _s , the colored metal compound n and the colorless metal compound n ₀ , the reflectance can be increased, and the saturation can be increased. Can be increased. Specifically, a combination of mica (refractive index 1.58), iron oxide (Fe ₂ O ₃ ) (refractive index 3.01), and titanium oxide (refractive index 2.5 to 2.7) is particularly preferable.
In particular, when used in makeup cosmetics, the part that faces the viewer is glossy, but the part that does not face the face does not have a whitish texture like conventional titanium oxide-coated mica, and is naturally reddish. The result is a shaded finish with a more natural skin finish.

  The pearl pigment of the present invention can be produced, for example, by using a neutralization titration method and selecting the addition rate of the colored metal oxide precursor aqueous solution. In order to reduce the surface average roughness of the colored metal or colored metal oxide, the neutralization titration method is preferable.
