【発明の属する技術分野】
本発明は、メーキャップ化粧料に関する。さらに詳しくは、優れたシミ・ソバカス・くすみ等の色ムラや毛穴、しわ等の肌の凹凸等の肌の欠点を補正する効果をもち、自然な透明感と充分な発色・光沢のある肌への仕上りが得られ、しかもその仕上りはどのような角度から見ても鮮やかな色調が見られるメーキャップ化粧料に関する。
【0002】
【従来の技術】
近年、メーキャップ化粧料には、シミ・ソバカス・くすみ等の色ムラや毛穴、しわ等の肌の凹凸といった欠点を補正しながら、自然な透明感と充分な発色・光沢のある肌への仕上りといった「美的」機能が求められている。
【0003】
従来、メーキャップ化粧料に光沢を付与するために、雲母や合成マイカに酸化チタンを被覆した雲母チタン(パール顔料)が用いられてきた。これらのパール顔料は干渉光を有するものもあり、微妙な発色と光沢のある仕上りによって、メーキャップ化粧料使用者の喜びや満足感を与えてきた。
【0004】
しかしながら、従来の雲母チタンでは、「肌のぎらつき感」といった不自然な仕上がりになることが多く、特に、つやを上げるためにパール顔料の配合量を増やすと、ぎらつき感が強くなり、てかりが生じ実際の肌とは全く異質な仕上がりとなる。また、光沢感があるものの干渉光の彩度(発色)は低く、発色を向上させるために有機色素や無機色材を多量配合したとしても、減法混色となり光による発色とは質感が全く異なり、仕上がりの満足できるものではない。
【0005】
以上から、より高いメーキャップ性やファッション性を付与するには限界があり、そのためメーキャップ製品愛用者の強い要望に答えることは出来なかった。
【0006】
また、シミ、ソバカス、くすみ等の色ムラ等の肌の欠点を目立たなくさせるために、パール顔料が特定の波長の光に対するフィルター効果を有していることを利用して配合されている。そして、濃色部分の調整を自然な色に見せるために酸化鉄等の着色顔料が併用されている。
【0007】
しかしながら、パール顔料の使用により毛穴等の凹凸が目立つようになったり、併用される着色顔料が屈折率が高く、透明感に欠けるため、不自然な感じの化粧肌になり、素肌っぽい自然な仕上がりが得られない。
【0008】
以上のように、従来のメーキャップ化粧料は、近年のメーキャップ化粧料に要求されている「美的」機能を充分満足するものではなかった。
【0009】
【発明が解決しようとする課題】
本発明は上記事情に鑑みてなされたもので、その目的は、シミ・ソバカス・くすみ等の色ムラや毛穴、しわ等の肌の凹凸等の肌の欠点を補正する効果をもち、自然な透明感と充分な発色・光沢のある肌への仕上りが得られるメーキャップ化粧料を提供することにある。
【0010】
【課題を解決するための手段】
本発明者らは上記課題を解決するために鋭意研究を行った結果、体質顔料は、干渉光の彩度が低いパール顔料に対しては、その干渉光を利用した発色や仕上がり感を向上させることはできないが、パール顔料の彩度を高くすると向上させ、さらに、特定の屈折率を持った体質顔料を使用することにより、その機能はアップすることを見出し、その研究成果から発展させ、高い彩度の干渉光を有する薄片状粉体と特定の形状と特定の屈折率を有する粉末とを併用することにより、上記課題が解決されることを見出し、本発明を完成するに至った。
【0011】
すなわち、本発明は、次の成分(A)及び(B)を含有することを特徴とするメーキャップ化粧料である。
(A)干渉色を有する平均粒子径1〜60μmの薄片状粉体であって、この粉体をニトロセルロースと、粉体:ニトロセルロース=1:15(質量比)の割合で混合し、白黒下地のカラーマッチングペーパーに0.101mmの膜厚で塗布した時の塗膜の光学特性が、マンセル表色系において黒下地の塗膜の色相(H)がP、RP、R領域では彩度(C)が5.0以上、色相(H)がYR、Y領域では彩度(C)が2.5以上、色相(H)がGY、G、BG領域では彩度(C)が3.0以上、色相(H)がB、PB領域では彩度(C)が7.3以上である薄片状粉体をメーキャップ化粧料全量中0.1〜50質量%。

【0012】
前記(A)成分である薄片状粉体は、雲母、合成マイカ、酸化チタン、酸化ケイ素(シリカ)、酸化アルミニウム(アルミナ)及びオキシ塩化ビスマスからなる群より選ばれた1種または2種以上によって構成された薄片状粉体であることができる。
【0013】
また、前記(A)成分である薄片状粉体は、薄片状粉末からなる母粉末に金属酸化物が被覆された薄片状粉体であることができ、前記母粉末は、雲母、合成マイカ、板状酸化ケイ素(シリカ)及び板状酸化アルミニウム(アルミナ)からなる群より選ばれた1種または2種以上であることが好ましく、前記金属酸化物は、酸化チタン、酸化ケイ素(シリカ)、酸化亜鉛、酸化アルミニウム(アルミナ)及びオキシ塩化ビスマスからなる群より選ばれた1種または2種以上であることが好ましく、特に、酸化チタン及び/又は酸化ケイ素(シリカ)であることが好ましい。
【0014】
前記(A)成分である薄片状粉体の好ましい態様の一つは、雲母、合成マイカ、板状酸化チタン、板状酸化ケイ素(シリカ)、板状酸化アルミニウム(アルミナ)、板状硫酸バリウム及びオキシ塩化ビスマスからなる群より選ばれた1種の薄片状粉末を母粉末とし、前記母粉末上に酸化チタン、板状酸化ケイ素(シリカ)、酸化亜鉛、酸化アルミニウム(アルミナ)及びオキシ塩化ビスマスからなる群より選ばれた2種以上の金属酸化物が被覆された3層以上の層状構造からなる薄片状粉体である。
【0015】
前記(A)成分である薄片状粉体の他の好ましい態様は、雲母又は合成マイカを母粉末とし、その上に酸化チタン及び酸化ケイ素(シリカ)が層状構造をとって被覆された層状薄片状粉体であり、特に雲母又は合成マイカを母粉末とし、その上に酸化チタンが被覆され、さらにその上に少なくとも一層の酸化ケイ素(シリカ)及び少なくとも一層の酸化チタンが交互に層状構造をとって被覆された層状薄片状粉体である。
【0016】
さらに、他の好ましい前記層状薄片状粉体の態様は、雲母又は合成マイカを母粉末とし、酸化チタン、酸化ケイ素(シリカ)、酸化チタンの順で交互に層状構造をとって被覆された4層状薄片状粉体である。
【0017】
また、前記(B)成分である粉末は、体質顔料が好ましく、具体的な好ましい体質顔料として、窒化ホウ素、硫酸バリウム、酸化アルミニウム(アルミナ)を挙げることができる。
【0018】
本発明においては、(A)成分と(B)成分の含有割合が質量比で(A):(B)=1:50〜50:1であり、(A)成分と(B)成分の総和の含有量がメーキャップ化粧料全量中0.2〜70質量%であることが好ましい。
【0019】
【発明の実施の形態】
以下、本発明の実施形態について詳述する。
【0020】
本発明において用いられる(A)成分は、干渉色を有する平均粒子径1〜60μmの薄片状粉体であって、この粉体をニトロセルロースと、粉体:ニトロセルロース=1:15(質量比)の割合で混合し、白黒下地のカラーマッチングペーパーに0.101mmの膜厚で塗布した時の塗膜の光学特性が、マンセル表色系において黒下地の塗膜の色相(H)がP、RP、R領域では彩度(C)が5.0以上、色相(H)がYR、Y領域では彩度(C)が2.5以上、色相(H)がGY、G、BG領域では彩度(C)が3.0以上、色相(H)がB、PB領域では彩度(C)が7.3以上である薄片状粉体である。
【0021】
すなわち、(A)成分である薄片状粉体は、高い彩度の干渉光を有するものであり、この干渉光の彩度は、(A)成分である薄片状粉体をニトロセルロースと、粉体:ニトロセルロース=1:15(質量比)の割合で均一に混合し、白黒下地のカラーマッチングペーパー上に0.101mmの塗膜とした時の光学特性が、マンセル表色系において黒下地の塗膜の色相(H)がP、RP、R領域では彩度(C)が5.0以上であるが、好ましくは5.3以上である。また、色相(H)がYR、Y領域では彩度(C)が2.5以上であるが、好ましくは2.8以上である。また、色相(H)がGY、G、BG領域では彩度(C)が3.0以上であるが、好ましくは3.5以上である。さらに、色相(H)がB、PB領域では彩度(C)が7.3以上であるが、好ましくは7.5以上である。本発明においては、(A)成分である薄片状粉体が1種又は2種以上選択され用いられる。
【0022】
前記(A)成分である薄片状粉体の色相及び彩度を測定する際に、黒下地上の塗膜の色相及び彩度を測定する理由は、高彩度の前記(A)成分である薄片状粉体において生起される干渉光の色調を効率よく測定するためである。
【0023】
なお、本発明では前記(A)成分である薄片状粉体の色相及び彩度を測定するのに測色機として、ミノルタ株式会社製のCM1000(登録商標)で測定し、その測定値として求められたもので条件付けを行っている。
【0024】
このように本発明に係る化粧料において、(A)成分である薄片状粉体の前記条件を満たす色相及び彩度は、主として入射光の一部に位相差を付与して再合成し、特定波長領域の光成分を干渉により強調して入射光とは異なる色調の着色光を生起させ、前記生起された着色光によって付与されていることが好適である。
【0025】
本発明においては、彩度が上記限定された数値より低いと充分な発色を行うことができず、特定形状の粉末と併用してもその化粧料は仕上がりに鮮やかさがなくなってしまう。また、角度によらない色調の見え方、自然な透明感、肌の欠点補正効果の点でも満足するものが得られない。
【0026】
本発明にける(A)成分である薄片状粉体の具体的構造は、上記特定の干渉光の彩度を有する薄片状の粉体であればよく、特に限定されないが、雲母、合成マイカ、酸化チタン、酸化ケイ素(シリカ)、酸化アルミニウム(アルミナ)及びオキシ塩化ビスマスからなる群より選ばれた1種または2種以上によって構成された薄片状粉体であることが好ましい。さらに好ましくは、薄片状粉末からなる母粉末に金属酸化物が被覆された薄片状粉体である。
【0027】
前記好ましく用いられる薄片状粉末からなる母粉末に金属酸化物が被覆された薄片状粉体を構成し母粉末となる薄片状粉末としては、例えば雲母、合成マイカ(合成フッ素金雲母等)、板状酸化ケイ素(シリカ)、板状酸化アルミニウム(アルミナ)、板状硫酸バリウム、板状酸化チタン、オキシ塩化ビスマス等が挙げられ、これらの1種又は2種以上を選択して使用することができる。これらの中で、特に雲母、合成マイカ(合成フッ素金雲母等)、板状酸化ケイ素(シリカ)、板状酸化アルミニウム(アルミナ)が好ましい。
【0028】
また、前記好ましく用いられる薄片状粉末からなる母粉末に金属酸化物が被覆された薄片状粉体を構成する金属酸化物としては、酸化チタン、オキシ塩化ビスマス、酸化ケイ素(シリカ)、酸化アルミニウム(アルミナ)、酸化亜鉛等が挙げられ、これらの1種又は2種以上を選択して使用することができ、特に酸化チタン及び/又は酸化ケイ素(シリカ)が好ましい。
【0029】
また、本発明において、(A)成分である薄片状粉体は、母粉末として、雲母、合成マイカ(合成フッ素金雲母等)、板状酸化ケイ素(シリカ)、板状酸化アルミニウム(アルミナ)、板状硫酸バリウム、板状酸化チタン及びオキシ塩化ビスマスの中から選択される1種の薄片状粉末を使用し、前記母粉末上に酸化チタン、オキシ塩化ビスマス、酸化ケイ素(シリカ)、酸化アルミニウム(アルミナ)及び酸化亜鉛のいずれか2種以上の金属酸化物を被覆して3層以上の層状構造を為していることが好適である。
【0030】
このように、多層の層状構造を取ることによって、高彩度の粉体に入射する白色光に対して多重の干渉を生起させることができるため、各層の厚さを調整することによって色調を調整することができ、かつ高彩度の干渉光を得ることが可能なのである。
【0031】
本発明においては、上記特定の干渉光の彩度を有する薄片状粉体が、雲母または合成マイカに、酸化チタン及び酸化ケイ素(シリカ)が層状構造をとって被覆された層状薄片状粉体であることが好ましい。
【0032】
中でも、多層の層状構造をとる前記(A)成分である薄片状粉体としては、雲母又は合成マイカを母粉末とし、酸化チタンが被覆され、さらにその上に少なくとも一層の酸化ケイ素(シリカ)及び少なくとも一層の酸化チタンが交互に層状構造をとって被覆された層状薄片状粉体であることが好ましい。
【0033】
特に、前記層状薄片状粉体が、雲母又は合成マイカを母粉末とし、酸化チタン、酸化ケイ素(シリカ)、酸化チタンの順で交互に層状構造をとって被覆された4層状薄片状粉体であると、従来の雲母チタンと変らない使用感や、光、熱、化粧料成分に対して安定性をもつ上、非常に彩度の高い干渉光を得ることができるため好適である。
【0034】
本発明における(A)成分である薄片状粉体の粒子径は、平均粒子径1〜60μmであり、好ましくは5〜30μmである。1μm未満では干渉光が弱くなり、特定の体質顔料との相乗的な発色効果が減少し、60μmを超えるとぎらつきなどの正反射の光沢が強くなり過ぎて、特定の体質顔料によるどのような角度でも見られていた発色効果が見られない。
【0035】
本発明における(A)成分として好ましく用いられる薄片状粉末からなる母粉末に金属酸化物が被覆された薄片状粉体は、前記母粉末を通常の方法に従って金属酸化物粒子で被覆する方法で調製されるが、市販品を用いることが可能である。市販品としては、例えば、チミロンスプレンディド(登録商標;以下記載省略)ゴールド(Timiron Splendid Gold)、チミロンスプレンディドブルー(Timiron Splendid Blue)、チミロンスプレンディドレッド(Timiron Splendid Red)、チミロンスプレンディドグリーン(Timiron Splendid Green)(いずれもMERCK社製)等が挙げられる。
【0036】
本発明で用いられる前記(A)成分である薄片状粉体は、発明の効果を損なわない範囲で、通常の化粧料顔料に用いられる処理剤、例えばシリコーン、金属石鹸、フッ素化合物等で表面処理したものを用いることもできる。
【0037】
本発明において用いられる(A)成分である薄片状粉体の含有量は、メーキャップ化粧料全量中0.1〜50質量%である。好ましくは、0.5〜20質量%である。含有量が0.1質量%未満では、発明の効果が充分に得られない。一方、50質量%を超えると、(A)成分の干渉色が強すぎて逆に化粧効果を損なう場合があり好ましくない。
【0038】
次に、本発明において用いられる(B)成分について詳述する。本発明における(B)成分は、粉末粒子の短径と長径の比(短径/長径)が1/1〜1/40であり、厚さと長径の比(厚さ/長径)が1/2以下であり、かつ屈折率が1.60〜2.15の粉末である。
【0039】
前記粉末粒子の短径と長径の比(短径/長径)は1/1〜1/40であるが、好ましくは1/1〜1/10である。また、厚さと長径の比(厚さ/長径)は1/2以下であるが、好ましくは1/5以下である。なお、下限は存在するもの、存在し得るものあるいは合成可能のものであれば効果の点からは特に限定されないが、1/100程度である。また、屈折率は1.60〜2.15であるが、好ましくは1.60〜2.00である。
【0040】
上記短径と長径の比が1/40より長径が長くなると、塗布時ののび等の使用性が劣るようになる。また、厚さ/長径が1/2を超えて厚くなると、セット感が悪くなり使用性が劣るようになる。また、屈折率が1.60より低くなると、充分な化粧効果が得られず、2.15より高くなると、透明性が失われ、化粧後の仕上がりが不自然になる。
【0041】
本発明にける(B)成分である粉末は、上記特定形状及び屈折率を有するものであればよく、特に限定されず、一般に化粧料に用いられる粉末の中から選ぶことができるが、体質顔料が好ましい。体質顔料としては、例えば、酸化マグネシウム、酸化アルミニウム(アルミナ)、硫酸バリウム、窒化ホウ素、酸化亜鉛、オキシ塩化ビスマス等が挙げられ、これらの1種又は2種以上を選択して使用することができる。これらのうち、特に硫酸バリウム、酸化アルミニウム(アルミナ)、窒化ホウ素からなる群から選ばれる1種または2種以上であることが好ましく、特に硫酸バリウムが好ましい。
【0042】
本発明における(B)成分である粉末の粒子径(粒径とも記載し、粉末を球と仮定した場合の粒子径である。)は、平均粒子径で0.1〜40μmが好ましい。粒子径が上記範囲を外れると本発明の効果が充分に得られなくなる。
【0043】
本発明で用いられる前記(B)成分である粉末は、発明の効果を損なわない範囲で、通常の化粧料顔料に用いられる処理剤、例えばシリコーン、金属石鹸、フッ素化合物等で表面処理したものを用いることもできる。
【0044】
本発明において用いられる(B)成分である粉末の含有量は、メーキャップ化粧料全量中0.1〜50質量%である。好ましくは、0.5〜30質量%である。含有量が、0.1質量%未満では、本発明の効果が充分に得られない。一方、50質量%を超えると、使用性を損なう等の問題が生じる場合があり、好ましくない。
【0045】
本発明においては、(A)成分と(B)成分の含有割合が質量比で(A):(B)=1:50〜50:1(以下、単に比率で示すが、全て質量比である。)であることが好ましい。さらに好ましくは、1:15〜15:1である。(A)が過剰な場合、「肌のぎらつき感」や「肌の凹凸」が目立ちやすくなる。また(B)が過剰な場合自然な透明感が得られない傾向にある。また、(A)成分と(B)成分の総和の含有量がメーキャップ化粧料全量中0.2〜70質量%であることが好ましい。さらに好ましくは、0.2〜70質量%である。(A)、(B)の総和の含有量が0.2質量%未満の場合には発明の効果が充分得ることができず、逆に70質量%を超える場合ではのびが重くなるといった使用感触の低下や「不自然な厚づき感」が目立つといった傾向が見られる。

BACKGROUND OF THE INVENTION
The present invention relates to makeup cosmetics. More specifically, it has the effect of correcting skin defects such as excellent color unevenness such as spots, freckles, dullness, skin irregularities such as pores, wrinkles, etc., to natural transparent feeling and sufficient color development / glossy skin The finish is related to makeup cosmetics that can be seen vivid colors from any angle.
[0002]
[Prior art]
In recent years, makeup cosmetics have a natural transparency and a sufficient color and glossy finish, while correcting defects such as color unevenness such as spots, freckles, dullness, and skin irregularities such as pores and wrinkles. “Aesthetic” functions are required.
[0003]
Conventionally, mica titanium (pearl pigment) in which mica or synthetic mica is coated with titanium oxide has been used to give gloss to makeup cosmetics. Some of these pearl pigments have interference light, and they have given joy and satisfaction to makeup cosmetics users through subtle color development and glossy finish.
[0004]
However, the conventional titanium mica often produces an unnatural finish such as “feeling of glare in the skin”, and in particular, increasing the blending amount of the pearl pigment to increase the gloss increases the feeling of glare. The result is that the skin is completely different from the actual skin. In addition, although there is a glossy feeling, the interference light has low saturation (color development), and even if a large amount of organic dyes or inorganic colorants are blended to improve color development, it becomes subtractive color mixing and the texture is completely different from color development by light, The finish is not satisfactory.
[0005]
From the above, there is a limit to the provision of higher makeup and fashionability, so it was not possible to answer the strong demands of users of makeup products.
[0006]
Further, in order to make skin defects such as color unevenness such as spots, freckles and dullness inconspicuous, pearl pigments are blended utilizing the fact that they have a filter effect on light of a specific wavelength. In order to make the adjustment of the dark color portion look natural, a coloring pigment such as iron oxide is used in combination.
[0007]
However, due to the use of pearl pigments, irregularities such as pores become conspicuous, and the color pigment used in combination has a high refractive index and lacks transparency, resulting in an unnatural-looking makeup skin, natural skin-like natural The finish is not obtained.
[0008]
As described above, the conventional makeup cosmetics do not sufficiently satisfy the “aesthetic” function required for the makeup cosmetics in recent years.
[0009]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and has an object of correcting natural skin defects such as color unevenness such as spots, freckles, and dullness, skin irregularities such as pores and wrinkles, and is naturally transparent. The object of the present invention is to provide a makeup cosmetic that can give a feeling to the skin and a sufficient color and gloss.
[0010]
[Means for Solving the Problems]
As a result of intensive studies to solve the above problems, the present inventors have improved the color development and finish feeling using the interference light for the pearl pigment having a low saturation of the interference light. It is not possible to improve the function of pearl pigments by increasing the saturation, but by using extender pigments with a specific refractive index, it has been found that its functions can be improved and developed from its research results. It has been found that the above-mentioned problems can be solved by using a flaky powder having a chroma interference light and a powder having a specific shape and a specific refractive index, and has completed the present invention.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
[0020]
The component (A) used in the present invention is a flaky powder having an interference color and an average particle diameter of 1 to 60 μm, and this powder is nitrocellulose and powder: nitrocellulose = 1: 15 (mass ratio). ) And the optical properties of the coating film when applied to a black and white base color matching paper with a film thickness of 0.101 mm, the hue (H) of the black base coating film in the Munsell color system is P, In the RP and R regions, the saturation (C) is 5.0 or more, the hue (H) is YR, in the Y region, the saturation (C) is 2.5 or more, and the hue (H) is in the GY, G, and BG regions. It is a flaky powder having a degree (C) of 3.0 or more, a hue (H) of B, and a saturation (C) of 7.3 or more in the PB region.
[0021]
That is, the flaky powder as the component (A) has high chroma interference light, and the saturation of the interference light is determined by changing the flaky powder as the component (A) with nitrocellulose and powder. Body: Nitrocellulose = 1: 15 (mass ratio) The mixture was uniformly mixed, and the optical characteristics when a 0.101 mm coating film was formed on a black-and-white base color matching paper showed that the black base in the Munsell color system When the hue (H) of the coating film is P, RP, or R, the saturation (C) is 5.0 or more, but preferably 5.3 or more. Further, the hue (H) is YR, and the saturation (C) is 2.5 or more in the Y region, but preferably 2.8 or more. In the GY, G, and BG regions, the saturation (C) is 3.0 or more, preferably 3.5 or more. Further, the hue (H) is B or PB and the saturation (C) is 7.3 or more, preferably 7.5 or more. In the present invention, one or more flaky powders as the component (A) are selected and used.
[0022]
When measuring the hue and saturation of the flaky powder as the component (A), the reason for measuring the hue and saturation of the coating film on the black base is the flaky shape as the component (A) with high saturation. This is for efficiently measuring the color tone of the interference light generated in the powder.
[0023]
In addition, in this invention, it measures by CM1000 (trademark) by Minolta Co., Ltd. as a colorimeter to measure the hue and saturation of the flaky powder which is the component (A), and obtains the measured value. Conditioning is done with
[0024]
Thus, in the cosmetic according to the present invention, the hue and saturation satisfying the above conditions of the flaky powder which is the component (A) are mainly recombined by adding a phase difference to a part of the incident light and specifying It is preferable that the light component in the wavelength region is emphasized by interference to generate colored light having a color tone different from that of the incident light, and is provided by the generated colored light.
[0025]
In the present invention, if the saturation is lower than the above-mentioned limited numerical value, sufficient color development cannot be performed, and even if it is used in combination with a powder having a specific shape, the cosmetic will lose vividness. Further, a satisfactory color tone appearance regardless of angle, natural transparency, and skin defect correction effect cannot be obtained.
[0026]
The specific structure of the flaky powder as the component (A) in the present invention is not particularly limited as long as it is a flaky powder having the saturation of the specific interference light, but is not limited to mica, synthetic mica, It is preferably a flaky powder composed of one or more selected from the group consisting of titanium oxide, silicon oxide (silica), aluminum oxide (alumina) and bismuth oxychloride. More preferably, it is a flaky powder in which a metal powder is coated on a mother powder made of a flaky powder.
[0027]
Examples of the flaky powder constituting the mother powder comprising the flaky powder coated with a metal oxide on the mother powder made of the flaky powder are preferably mica, synthetic mica (synthetic fluorine phlogopite, etc.), plate Examples thereof include silicon oxide (silica), plate-like aluminum oxide (alumina), plate-like barium sulfate, plate-like titanium oxide, and bismuth oxychloride. One or more of these can be selected and used. . Of these, mica, synthetic mica (synthetic fluorine phlogopite, etc.), plate-like silicon oxide (silica), and plate-like aluminum oxide (alumina) are particularly preferable.
[0028]
Examples of the metal oxide constituting the flaky powder in which the mother powder made of the flaky powder preferably used is coated with a metal oxide include titanium oxide, bismuth oxychloride, silicon oxide (silica), aluminum oxide ( Alumina), zinc oxide, and the like, and one or more of these can be selected and used, and titanium oxide and / or silicon oxide (silica) is particularly preferable.

[0030]
In this way, by adopting a multi-layered structure, multiple interference can be caused to white light incident on high-saturation powder, so the color tone can be adjusted by adjusting the thickness of each layer It is possible to obtain interference light with high saturation.
[0031]
In the present invention, the flaky powder having the specific interference light saturation is a lamellar flaky powder in which mica or synthetic mica is coated with titanium oxide and silicon oxide (silica) in a layered structure. Preferably there is.
[0032]
Among them, as the flaky powder as the component (A) having a multi-layered structure, mica or synthetic mica is used as a mother powder, titanium oxide is coated thereon, and at least one layer of silicon oxide (silica) and It is preferably a layered flaky powder in which at least one layer of titanium oxide is alternately coated with a layered structure.
[0033]
In particular, the layered flaky powder is a four-layered flaky powder coated with a mica or synthetic mica as a mother powder and alternately having a layered structure in the order of titanium oxide, silicon oxide (silica), and titanium oxide. In this case, it is preferable because it has the same feeling of use as conventional titanium mica and has stability to light, heat, and cosmetic ingredients, and can obtain interference light with very high saturation.
[0034]
The particle size of the flaky powder which is the component (A) in the present invention is an average particle size of 1 to 60 μm, preferably 5 to 30 μm. If it is less than 1 μm, the interference light becomes weak, the synergistic coloring effect with a specific extender pigment decreases, and if it exceeds 60 μm, the gloss of specular reflection such as glare becomes too strong, The coloring effect seen at an angle is not seen.
[0035]
The flaky powder in which the mother powder composed of the flaky powder preferably used as the component (A) in the present invention is coated with the metal oxide is prepared by a method in which the mother powder is coated with metal oxide particles according to a usual method.

[0037]
The content of the flaky powder as the component (A) used in the present invention is 0.1 to 50% by mass in the total amount of the makeup cosmetic. Preferably, it is 0.5-20 mass%. When the content is less than 0.1% by mass, the effects of the invention cannot be sufficiently obtained. On the other hand, if it exceeds 50% by mass, the interference color of the component (A) is too strong and the cosmetic effect may be adversely affected.
[0038]
Next, (B) component used in this invention is explained in full detail.

This is a powder having a refractive index of 1.60 to 2.15.
[0039]
The ratio of the minor axis to the major axis (minor axis / major axis) of the powder particles is 1/1 to 1/40, preferably 1/1 to 1/10. The ratio of thickness to major axis (thickness / major axis) is ½ or less, but preferably 5 or less. The lower limit is not particularly limited in terms of effect as long as it exists, can exist, or can be synthesized, but is about 1/100. Moreover, although a refractive index is 1.60-2.15, Preferably it is 1.60-2.00.
[0040]
When the ratio of the minor axis to the major axis is longer than 1/40, the usability such as stretching at the time of coating becomes inferior. On the other hand, when the thickness / major axis exceeds 1/2, the feeling of setting becomes worse and the usability becomes inferior. On the other hand, if the refractive index is lower than 1.60, a sufficient makeup effect cannot be obtained, and if it is higher than 2.15, the transparency is lost and the finish after makeup becomes unnatural.

On the other hand, if it exceeds 50% by mass, problems such as impaired usability may occur, which is not preferable.
[0045]
In the present invention, the content ratio of the component (A) and the component (B) is a mass ratio of (A) :( B) = 1: 50 to 50: 1 (hereinafter simply indicated as a ratio, but all are mass ratios). .). More preferably, it is 1: 15-15: 1. When (A) is excessive, “skin glare” and “unevenness of skin” tend to be noticeable. Further, when (B) is excessive, natural transparency tends to be not obtained.
