Description

【0001】
【発明の属する技術分野】
本発明は、透明感を持たせつつ、肌の色相感覚を変化させることができ、かつ不自然なぎらつきのない化粧料に関する。
【0002】
【従来の技術】
基礎化粧料、メークアップ化粧料は、これを塗布して肌の質感を変化させるため、拡散反射の強い粉体を配合してマットな仕上がりを得たり、マイカ等の鏡面反射の強い粉体を配合してつやのある仕上がりを得たりしている。また、血行不良や加齢等による肌のくすみ(肌が暗く、黄色っぽくなる状態)、あるいはシミ・ソバカス等の色むらをカバーするため、二酸化チタンや酸化鉄等の隠蔽力の高い顔料を配合したり、ベンガラ、レーキ顔料や有機顔料等の赤みを加えて肌の色相感覚を変化させることが行われている。
一方、赤ら顔やにきび跡を隠すために、赤の補色である緑色の顔料を使用したり、透明感を与えるために青色や紫色の顔料を使用して、肌の色相感覚を変化させることが行われている。
【0003】
しかしながら、隠蔽力の高い顔料を用いた場合には、自然な感じがなくなってしまうという問題がある。また、補色の原理を利用した場合には、色相の調整はできるものの彩度が低下し、反対に肌色がくすんでしまうという問題がある。これらの問題は、その方法が減法混色に基づく色相コントロールであるために生じるものであり、色を重ねれば重ねるだけ、彩度が低下して灰色に近づいてしまうことが原因である。また、色相感覚の変化を大きくするために配合量を増加すると不自然なぎらつきが出てしまう。
【0004】
【発明が解決しようとする課題】
本発明の目的は、透明感を持たせつつ肌の色相を変化させることができ不自然なぎらつきのない化粧料を提供することにある。
【0005】
【課題を解決するための手段】
本発明者らは、中空構造の二酸化チタン板状粉体と二酸化チタン被覆雲母を併用することにより、透明感を持たせつつ、肌の色相感覚を変化させることができかつ不自然なぎらつきのない化粧料が得られることを見出した。
すなわち、本発明は、次の成分(A)及び(B)
(A)中空構造の二酸化チタン板状粉体、
(B)二酸化チタン被覆雲母
を含有し、成分(A)と成分(B)を合わせた配合量が0.1〜50重量%であり、成分(A)と成分(B)の重量比率が1/10〜10/1である化粧料を提供するものである。
【0006】
【発明の実施の形態】
本発明で使用する中空構造の金属酸化物板状粉体((A)成分)の「板状粉体」とは、アスペクト比(粉体の長軸の長さと厚さとの比)が5〜100の範囲である粉体をいい、特に摩擦係数を小さくして使用感を良好にする点、及び製造の容易さの点から、アスペクト比は10〜70の範囲が好ましい。また平均粒径(レーザー回折/散乱式粒度分布測定装置により測定)は、使用感を良好にする点、及びギラツキ感を低減する点から、12μm以下、特に5〜12μmの範囲が好ましい。
【0007】
板状粉体を構成する金属酸化物としては、例えば二酸化チタン、酸化鉄、酸化ジルコニウム及び酸化スズ等の屈折率の高いもの(例えば屈折率1.7〜2.8)が好ましく、特に二酸化チタン(屈折率2.5〜2.7)が好ましく、中でもその結晶系がルチル型の二酸化チタン(屈折率2.7)がより好ましい。
【0008】
(A)成分は、金属酸化物からなる板状粉体であって、内部に空洞を有するものである。例えば雲母、硫酸カルシウム等の板状基体上に金属酸化物を被覆し、その後、基体物質のみを酸又はアルカリにより溶解除去して粉体内部を中空状とする方法により製造することができる(特開昭55−60565号公報、特開平9−194757号公報、特開昭49−45129号公報)。ここで板状基体としては、雲母、例えば白雲母、黒雲母、金雲母等;硫酸カルシウム、例えば二水石膏等が使用可能であるが、特に雲母が好ましい。また基体物質の溶解に用いられる酸としては、フッ化水素酸、塩酸、硫酸、硝酸、リン酸等の鉱酸が挙げられ、アルカリとしては水酸化ナトリウム、水酸化カリウム等が挙げられる。基体として用いた雲母、硫酸カルシウム等の物質は、生成板状粉体中に20重量%程度残存してもよいが、干渉色の強さの点で、その残存量は低ければ低いほど好ましい。この点で、金属酸化物被覆板状粉体を鉱酸を含有する酸水溶液と接触させた後、アルカリ水溶液と接触させる方法が、基体物質の含有率をより下げることができ好ましい(特開平9−194757号公報)。かかる中空板状粉体の表面は、一部に金属酸化物層の欠損があっても良い。
また、基体物質を溶解する前の金属酸化物被覆板状粉体の金属酸化物の光学的厚み(被覆厚)をコントロールすることにより、様々な色調をつくりだすことが可能である。更に、2種類以上の板状粉体を組み合わせて用いることにより、様々な色調をつくりだすことも可能である。
【0009】
(A)成分の中空構造の金属酸化物板状粉体は、化粧持ち(持続性)向上の点からその表面を疎水化処理して用いてもよい。尚、疎水化処理は、通常の方法に従い疎水化処理剤で処理することにより行われる。該疎水化処理剤としては、シリコーン油、脂肪酸金属塩、アルキルリン酸、アルキルリン酸のアルカリ金属塩又はアミン塩、N−モノ長鎖(炭素数8〜22)脂肪族アシル塩基性アミノ酸、パーフルオロアルキル基を有するフッ素化合物などが挙げられる。
シリコーン油としては、例えば各種鎖状シリコーン、環状シリコーン、変性シリコーンが;脂肪酸金属塩としては、特に炭素数12〜18の脂肪酸のカルシウム、マグネシウム、亜鉛、アルミニウム等の塩が;アルキルリン酸及びその塩としては、合計炭素数8〜45のアルキル又はアルケニル基を有するモノ又はジエステル及びアルカリ金属塩若しくはアミン塩が;N−モノ長鎖脂肪族アシル塩基性アミノ酸としては、2−エチルヘキサノイル、カプリロイル、ラウロイル、ミリストイル、パルミトイル、ステアロイル、イソステアロイル、オレオイル、ベヘノイル、ココイル、牛脂脂肪酸アシル、硬化牛脂脂肪酸アシル等の炭素数8〜22のアシル基が塩基性アミノ酸のα位又はω位のアミノ基に結合したものが;パーフルオロアルキル基を有するフッ素化合物としては、米国特許第3632744号明細書、特開昭62−250074号公報、特開昭55−167209号公報、特開平2−218603号公報等に記載のものが挙げられる。
【0010】
(A)成分の疎水化処理量は、十分な疎水性、良好な感触の点から、(A)成分1重量部に対して疎水化処理剤0.0005〜0.2重量部、特に0.02〜0.1重量部が好ましい。
【0011】
(B)成分は、板状の雲母粉体の表面を二酸化チタンで被覆したものである。本発明の(B)成分として好ましい平均粒径は12μm以下、特に5〜12μmの範囲が好ましい。平均粒径はレーザー回折/散乱式粒度分布測定法により測定される。ここで、二酸化チタンの結晶形は、ルチル型であることが好ましいが、それ以外の結晶形を含有しても良い。
かかる(B)成分の市販品としては、メルク社製のTimilon Supersilk MP1005やエンゲルハルド社製のFlamenco SATIN Violet等が例示できる。
【0012】
(B)成分は(A)成分と同様に疎水化処理して用いてもよい。
疎水化処理は、(A)成分を疎水化処理するときに用いる疎水化処理剤が使用される。
【0013】
(A)成分と(B)成分を合わせた粉体の配合量は、色相感覚を好適に変化させ、過度の光沢感のない自然な化粧仕上がりを得るために、0.1〜50重量%(以下、単に「%」で示す)が好ましい。また、同様の観点から(A)成分と(B)成分の配合比率は(A)/(B)=1/10〜10/1であり、特に3/10〜4/1が好ましい。
【0014】
本発明の化粧料は常法に従って製造することができ、例えば化粧水、乳液、クリーム等の基礎化粧料;粉白粉、固形白粉、フェイスパウダー、パウダーファンデーション、油性ファンデーション、クリーム状ファンデーション、リキッドファンデーション、コンシーラー、口紅、リップクリーム、頬紅、アイライナー、アイシャドウ、アイブロウ等のメークアップ化粧料などとすることができる。
【0015】
本発明の化粧料には(A)成分及び(B)成分のほかに、必要に応じて、通常の化粧料に配合されている成分、例えば、界面活性剤、水溶性高分子、他の粉体、保湿剤、防腐剤、薬剤、紫外線吸収剤、色素、無機塩又は有機酸塩、香料、キレート剤、pH調整剤、水等を配合することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a cosmetic that can change the skin hue sensation while having a transparent feeling and has no unnatural glare.
[0002]
[Prior art]
Basic cosmetics and makeup cosmetics are applied to change the texture of the skin, so they can be mixed with powders with strong diffuse reflection to obtain a matte finish, or powders with strong specular reflection such as mica. Blended to obtain a glossy finish. In addition, pigments with high hiding power such as titanium dioxide and iron oxide are included to cover dull skin due to poor blood circulation, aging, etc. (skin becomes dark and yellowish) or uneven color such as spots and freckles. In addition, redness of bengara, lake pigments, organic pigments and the like is added to change the skin hue sensation.
On the other hand, it is possible to change the skin's hue sensation by using a green pigment, which is a complementary color of red, to conceal redness and acne scars, or by using a blue or purple pigment to give a clear feeling. It has been broken.
[0003]
However, when a pigment with high hiding power is used, there is a problem that the natural feeling is lost. In addition, when the principle of complementary colors is used, there is a problem that the hue can be adjusted but the saturation is lowered and the skin color is dull. These problems occur because the method is a hue control based on subtractive color mixture, and is caused by the fact that if the colors are overlapped, the saturation is lowered and the color approaches gray. Further, if the blending amount is increased in order to increase the change in hue sensation, unnatural glare will appear.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide a cosmetic that can change the hue of the skin while having a transparent feeling and is free from unnatural glare.
[0005]
[Means for Solving the Problems]
The present inventors have used a hollow structure titanium dioxide plate-like powder and titanium dioxide-coated mica in combination, which can change the skin hue sensation while giving a sense of transparency and does not cause unnatural glare. It was found that a fee can be obtained.
That is, the present invention provides the following components (A) and (B)
(A) Titanium dioxide plate-like powder having a hollow structure,
(B) It contains titanium dioxide-coated mica, the combined amount of component (A) and component (B) is 0.1 to 50% by weight, and the weight ratio of component (A) and component (B) is 1. The cosmetic which is / 10-10 / 1 is provided.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The “plate-like powder” of the hollow-structure metal oxide plate-like powder (component (A)) used in the present invention has an aspect ratio (ratio of the length of the major axis of the powder to the thickness) of 5 to 5. The aspect ratio is preferably in the range of 10 to 70 in terms of the powder in the range of 100, particularly from the viewpoint of reducing the friction coefficient to improve the usability and the ease of production. The average particle size (measured with a laser diffraction / scattering particle size distribution measuring device) is preferably 12 μm or less, particularly preferably in the range of 5 to 12 μm, from the viewpoint of improving the feeling of use and reducing the feeling of glare.
[0007]
As a metal oxide which comprises plate-shaped powder, what has high refractive index (for example, refractive index 1.7-2.8), such as titanium dioxide, iron oxide, a zirconium oxide, and a tin oxide, for example is preferable, and especially titanium dioxide. (Refractive index of 2.5 to 2.7) is preferable, and among them, rutile type titanium dioxide (refractive index of 2.7) is more preferable.
[0008]
The component (A) is a plate-like powder made of a metal oxide and has a cavity inside. For example, it can be produced by a method in which a metal oxide is coated on a plate-like substrate such as mica and calcium sulfate, and then only the substrate material is dissolved and removed with an acid or alkali to make the inside of the powder hollow (special feature). JP 55-60565, JP 9-194757, JP 49-45129). Here, as the plate-like substrate, mica such as muscovite, biotite, phlogopite, etc .; calcium sulfate such as dihydrate gypsum can be used, and mica is particularly preferable. Examples of the acid used for dissolving the base material include mineral acids such as hydrofluoric acid, hydrochloric acid, sulfuric acid, nitric acid and phosphoric acid, and examples of the alkali include sodium hydroxide and potassium hydroxide. Substances such as mica and calcium sulfate used as the substrate may remain in the resulting plate-like powder in an amount of about 20% by weight, but the remaining amount is preferably as low as possible in terms of the intensity of interference color. In this respect, a method in which the metal oxide-coated plate-like powder is brought into contact with an acid aqueous solution containing a mineral acid and then brought into contact with an alkaline aqueous solution is preferable because the content of the base material can be further reduced (Japanese Patent Laid-Open No. 9-1993). -194757). The surface of the hollow plate-like powder may partially have a metal oxide layer defect.
Further, various color tones can be produced by controlling the optical thickness (coating thickness) of the metal oxide of the metal oxide-coated plate-like powder before dissolving the base material. Furthermore, various color tones can be produced by using a combination of two or more types of plate-like powders.
[0009]
The metal oxide plate-like powder having a hollow structure (A) may be used after its surface is hydrophobized from the standpoint of improving makeup durability (sustainability). The hydrophobizing treatment is performed by treating with a hydrophobizing agent according to a normal method.

【Example】
Production Example 1
1.0 g of anatase-type titanium oxide-coated mica exhibiting green interference light was weighed into a 250 mL polypropylene beaker, and further 50 mL of distilled water was added. A stir bar coated with plastic was added and placed on a heating mantle to allow temperature control. Under stirring, 5.0 mL of concentrated sulfuric acid was added from a glass pipette, and then 2.0 mL of concentrated hydrofluoric acid (50%) was added from a synthetic resin pipette.
The suspension was then heated at 70 ° C. for 1 hour. After adding 200 mL of distilled water, the slurry was filtered with a Buchner funnel and washed with 500 mL of distilled water to remove the remaining acid. The obtained powder was dried in an oven at 120 ° C. for 30 minutes to obtain a metal oxide plate-like powder having a hollow inside.
[0017]
Production Example 2
A suspension was prepared by mixing 90 g of rutile titanium oxide-coated mica exhibiting blue interference light, 124 g of sulfuric acid, 60 g of phosphoric acid, and 300 mL of distilled water. The suspension was refluxed at 120 ° C. for 6 hours, then cooled and filtered. The pressed cake was washed with distilled water until the pH of the eluate was 2, and then slurried with 800 mL of distilled water without drying. 83 g of sodium hydroxide was added to make a 9% sodium hydroxide solution and heated to 60 ° C. After stirring for 1 hour, the mixture was filtered, and the pressed cake was washed until the pH of the eluate reached 10. This product was dried at 100 ° C. for 14 hours to obtain a metal oxide plate-like powder having a hollow inside.
