Description

  The present invention relates to a dull skin concealment cosmetic compounded with titanium oxide having an average particle size of 0.5 to 2 μm, and a glittering powder having a purple interference reflection color. It is related to a dull skin concealment cosmetic that is excellent in the effect that the color difference between the dull part and the other part (skin color part without dullness) is naturally inconspicuous when applied to the whole face by a person with yellowish dullness. .

  Human fatigue often appears on the skin and often causes dullness (also called bears) in the eyes (under the eyes) due to lack of sleep, overwork, stress, and the like. When dullness occurs in the eyes, not only an unhealthy impression is given to a person, but even if makeup such as eye shadow is applied to the eyes, a sufficient makeup effect cannot be obtained. In particular, when working women get dull in the morning when they get up in the morning, they become depressed all day and try to hide dullness using cosmetics.

  Conventionally, in such a case, a cosmetic for hiding a dull portion using a pigment having a high refractive index such as titanium oxide has been used. However, simply concealing the dull part in this way results in an unnatural makeup state when applied to the entire face.

  In addition, in order to make dark skin areas such as nevus and hemangioma inconspicuous, we also developed technology that uses powders such as titanium mica that selectively transmit transmitted light that is complementary to the dark skin color. (For example, refer to Patent Document 1).

  On the other hand, in the present invention, titanium oxide having an average particle size of 0.5 to 2 μm is used, but titanium oxide used in cosmetics has an average particle size of 0.1 to 0.1 in makeup cosmetics that require a high refractive index. In general, titanium oxide having an average particle size of 0.02 to 0.08 μm has been widely used in cosmetics that require an ultraviolet shielding effect. However, titanium oxide having an average particle size of 0.5 to 2 μm has hardly been used. Further, in the present invention, a brilliant powder having a purple interference reflection color is used. Such powder has been widely used in makeup cosmetics such as eye shadow, nail polish and lipstick, but hides dull skin. It was not used as a cosmetic.

  However, the technique of Patent Document 1 can partially make the dark color portion of the skin inconspicuous, but cannot make the color difference between the dull portion and the other portion inconspicuous. That is, when the entire face is used, even if it is applied to both the dull portion and the other skin color portions, there is no sense of incongruity and the effect of naturally making the dull portion unnoticeable is not sufficient.

JP-A-8-81332

  Therefore, the development of cosmetics that make the color difference between the dull part and the other part (skin color part without dullness) as natural as possible by applying it to all faces by people with yellowish dullness in the eyes etc. is desired. It was rare.

  The present inventor has conducted extensive studies in the above-described actual situation, and when titanium oxide having an average particle diameter of 0.5 to 2 μm and glittering powder having a purple interference reflection color are combined, the titanium oxide is naturally dull. Furthermore, since the latter glittering powder emits transmitted light of the same color as the dull part, it has been found that the dull part is naturally unnoticeable by eliminating the color difference between the dull part and the other part. Completed the invention.

That is, the present invention includes the following components (a) and (b);
(A) Titanium oxide having an average particle diameter of 0.5 to 2 μm (b) A dull hiding cosmetic for skin characterized by blending a glittering powder with a purple interference reflection color.

In addition, the present invention provides the above-mentioned dull skin concealment cosmetic, wherein the component (b) has a dent at 470 to 550 nm in a spectral reflection curve obtained by the following measurement method.
Measuring method: A sample is uniformly coated on a black urethane sheet, and a spectral reflectance of 390 to 730 nm is measured with a variable angle spectrophotometer at an incident angle of 45 degrees and a light receiving angle of 30 degrees.

Furthermore, it provides the dull skin concealment cosmetic, wherein the component (b) has a convex at 510 to 570 nm in the spectral transmission curve obtained by the following measurement method.
Measuring method: 5 parts by mass of a sample dispersed in 50 parts by mass of a nitrified cotton solution (21 parts by mass of nitrified cotton, 21% by mass of ethyl acetate, 43.4% by mass of butyl acetate, 14.6% by mass of isopropyl alcohol), and optically polished quartz A thin film was formed on a plate with an applicator of 25 μm and dried, and a spectral transmittance of 390 to 730 nm was measured with a variable angle spectrophotometer at an incident angle of 0 degree and a light receiving angle of 30 degrees.

  Further, the present invention provides any one of the above-mentioned skin dullness-hiding cosmetics, wherein the skin dullness is a yellowish dullness.

  The skin dull concealment cosmetic of the present invention has the effect that the color difference between the dull part and the other part (skin color part without dullness) becomes inconspicuous by using the entire face by a person who has a yellowish dullness in the eyes etc. It is what has.

Hereinafter, the configuration of the present invention will be described in detail.
Component (a) used in the present invention is titanium oxide having an average particle size of 0.5 to 2 μm. Titanium oxide having an average particle size of less than 0.5 μm (conventional pigment-grade titanium oxide) can hide the dull part of the skin, but is unfavorable because it produces an unnatural finish. Titanium oxide having an average particle size exceeding 2 μm is not preferable because it is inferior in the effect of hiding the dull part of the skin. Pigments such as titanium oxide have a peak concealing property with an average particle diameter that approximates to half the wavelength of visible light, but both concealing properties decrease before and after that. In the present invention, the average particle diameter is a volume average diameter obtained by image analysis (LUZEX AP) of an electron micrograph (TEM).

  The crystal form of the component (a) titanium oxide may be any of anatase, rutile, brookite and the like, but the rutile type is preferable because it is excellent in the effect of naturally hiding the dull part of the skin. And the manufacturing method of such a titanium oxide may be obtained by any manufacturing methods, such as a chlorine method and a sulfuric acid method.

  As such a component (a) titanium oxide, commercially available products such as MP-70 having an average particle diameter of 0.7 μm, MP-100 having an average particle diameter of 1 μm (both manufactured by Teika) and the like can be used. .

  Furthermore, the titanium oxide of the component (a) is an inorganic compound such as alumina, silica, iron oxide, etc., which are usually known surface treatment agents, fluorine compounds, silicone compounds, phospholipids, phospholipid derivatives, metals, if necessary. It may be used after being surface-treated with soap, wax, surfactant, oil or fat, hydrocarbon or the like.

  The blending amount of the component (a) in the dull skin concealment cosmetic of the present invention is not particularly limited, but is preferably 1 to 15% by mass (hereinafter simply referred to as “%”). 8% is more preferable. When component (a) is used within this range, it is possible to obtain a dull cover-up cosmetic material with excellent dull cover-up effect.

  The component (b) used in the present invention is a glittering powder whose interference reflection color is purple. Such glitter powder is normally used as a glitter powder in makeup cosmetics, but in the present invention, visible light transmitted through component (b) has the same color as the yellowish dull part of the skin. Therefore, it has the effect of making the dullness of the skin inconspicuous.

It is preferable that the component (b) has a dent at 470 to 550 nm in a spectral reflection curve obtained by the following measurement method because the effect of making the dull portion of the skin inconspicuous is excellent.
Measurement method: A sample is uniformly applied on a black urethane sheet (Bioskin Beaulux) using a makeup brush, and a variable angle spectrophotometer (Murakami Color Research Laboratory Co., Ltd.) with an incident angle of 45 degrees and a light receiving angle of 30 degrees. The spectral reflectance of 390 to 730 nm was measured by GSP-1B type).

Furthermore, it is preferable that the component (b) has a convexity at 510 to 570 nm in the spectral transmission curve obtained by the following measurement method, because it is excellent in the effect of making the dull portion of the skin inconspicuous.
Measuring method: Disperse 5 parts by weight of a sample in 50 parts by weight of a nitrified cotton solution (21 parts by weight of nitrified cotton, 21% by weight of ethyl acetate, 43.4% by weight of butyl acetate, 14.6% by weight of isopropyl alcohol). A thin film was formed on an optically polished quartz plate with a 25 μm applicator, the solvent was dried, and the spectral transmittance of 390 to 730 nm was measured with a variable angle spectrophotometer at an incident angle of 0 degree and a light receiving angle of 30 degrees.

  Such a component (b) includes mica titanium, powder coated with silica on the surface of mica titanium and further coated with titanium oxide, iron oxide-coated mica, iron oxide-coated mica titanium, titanium oxide-coated synthetic phlogopite, iron oxide Examples thereof include titanium oxide-coated synthetic phlogopite, organic pigment-coated mica titanium, and titanium oxide-coated glass powder. These can be used alone or in combination. Among these, mica titanium and a powder in which the surface of mica titanium is coated with silica and further coated with titanium oxide are preferable. In the case of mica titanium, the mass composition of mica and titanium oxide is in the range of 49-60: 40-51. The mass composition of mica, titanium oxide, and anhydrous silicic acid in the powder in which the surface of titanium mica is coated with silica and further coated with titanium oxide is preferably in the range of 29-35: 49-59: 12-16. Among these, powders in which the mica titanium surface is coated with silica and further coated with titanium oxide are particularly preferable. Such a component (b) is composed of Timilon Splendid Violet (made by Merck) which is a powder obtained by coating silica on the surface of mica titanium and further coated with titanium oxide, Flamenco Violet 520C (made by Engelhard) which is mica titanium. Commercial products such as these can be used.
