Description
【０００１】
【発明の属する技術分野】
本発明は塗擦により液化する粉末化粧料に関する。さらに詳しくは、使用時に塗擦すると液化して乳液様の特性が生じる粉末化粧料であって、特に低温保存安定性に優れ、みずみずしい使用性を有するとともに、水の存在下で不安定な成分や、水に溶解した状態で製品の物性に悪影響を及ぼしたりする成分（以下、「水存在下不安定成分」と総称）を配合した場合でも、これら成分を安定に配合し、該成分の機能を十分に発揮し得る粉末化粧料に関する。
【０００２】
【従来の技術】
従来、いわゆるドライウォーターと称される粉末化粧料では、水や、水以外の水性成分を、疎水化処理した粉末等で被覆して粉末化し、使用時に塗擦すると液化するようになされている。これら粉末化粧料として、白粉、美白パウダー等が知られているが、仕上がりが粉っぽく、肌が乾燥しやすい等の問題があった。
【０００３】
また、一般に化粧料には、薬剤など種々の有効成分が配合されているが、この薬剤の肌への浸透性促進、保湿性、エモリエント性の付与等を目的として、粉末化粧料を水、油、液状化粧料等と混合して使用する方法も行われているが、使用性などの点で問題があった。さらに、この有効成分が、水の存在下で容易に分解、変質するなど不安定で製品の物性に悪影響を及ぼしたりするような場合、その配合は、化粧料の剤型のみならず、容器形態、保存条件、取り扱い等において種々の制約を受ける。
【０００４】
このような問題に対処すべく種々の技術が提案されている。例えば、特開平６−２１１６２０号公報には、特定の表面積を有する疎水化無水ケイ酸、フッ素化合物被覆処理化粧料粉体、油性成分、水性成分、および不安定有効成分（水存在下不安定成分）を特定量配合することによって、これら水存在下不安定成分の安定な配合を図った粉末化粧料が開示されている。
【０００５】
しかしながら、上記公報に記載の粉末化粧料においては、０℃若しくはそれ以下の低温で保存した際に水性成分が凍結するため、室温に戻すと融解に伴い離水が生じることから、製品の低温保存安定性の点において問題がある。
【０００６】
【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、粉末形態の化粧料でありながら使用時に塗擦すると液化して化粧水または乳液様の特性が生じる粉末化粧料であって、優れた低温保存安定性を有するとともに、みずみずしい使用性を有し、さらに、水存在下不安定成分を配合した場合でもこれら成分を安定に配合し、それらの機能を十分に発揮し得る塗擦により液化する粉末化粧料を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明は、（ａ）表面積６０ｍ2／ｇ以上の疎水化無水ケイ酸、（ｂ）微生物系水溶性高分子、セルロース系水溶性高分子、アルギン酸系水溶性高分子の中から選ばれる１種または２種以上、および（ｃ）水を含有し、パーフルオロポリエーテルアルキルリン酸及びその塩、パーフルオロポリエーテルアルキル硫酸及びその塩、パーフルオロポリエーテルアルキルカルボン酸及びその塩から選択される、分子量が３００以上であるパーフルオロポリエーテル基を有する化合物で処理した粉体を含む場合、その配合量が１重量％未満である、塗擦により液化する粉末化粧料に関する。
【０００８】
また本発明は、上記粉末化粧料にさらに（ｄ）水存在下不安定成分を含有する、塗擦により液化する粉末化粧料に関する。
【０００９】
【発明の実施の形態】
以下、本発明について詳述する。
【００１０】
本発明に用いられる（ａ）成分としての疎水化無水ケイ酸は、微粒子無水ケイ酸表面を疎水化処理したものである。
【００１１】
疎水化処理の方法としては、無水ケイ酸に撥水性を付与できる方法であればいかなるものでもよく、その方法は問わないが、例えば気相法、液相法、オートクレーブ法、メカノケミカル法等、通常の表面処理方法を用いることができる。
【００１２】
例えば疎水化処理剤を原料粉末に添加して処理を行う場合、適当な溶媒（ジクロルメタン、クロロホルム、ヘキサン、エタノール、キシレン、揮発性シリコーン等）に希釈して添加してもよく、あるいは直接添加してもよい。粉末と処理剤の混合攪拌には、ボールミル、ホジャーサイトボールミル、振動ボールミル、アトライター、ポットミル、ロッドミル、パンミル、ホモミキサー、ホモディスパー、ヘンシェルミキサー、ナウターミキサー等も使用することができる。この他にも、粉末表面の活性を利用し、気相反応により１００℃以下の低温で環状オルガノシロキサンを粉末表面上で重合させる方法（特公平１−５４３８０号）や、前記方法の後に表面のシリコーンポリマーのＳｉ−Ｈ部分にグリセロールモノアリルエーテル等のペンダント基を付加させる方法（特公平１−５４３８１号）等も用いることができる。
【００１３】
疎水化処理剤としては、特に限定されるものではないが、脂肪酸デキストリン処理粉末、トリメチルシロキシ珪酸処理粉末、フッ素変性トリメチルシロキシ珪酸処理粉末、メチルフェニルシロキシ珪酸処理粉末、フッ素変性メチルフェニルシロキシ珪酸処理粉末、ジメチルポリシロキサン、ジフェニルポリシロキサン、メチルフェニルポリシロキサン等の低粘度〜高粘度油状ポリシロキサン処理粉末、ガム状ポリシロキサン処理粉末、メチルハイドロジェンポリシロキサン処理粉末、フッ素変性メチルハイドロジェンポリシロキサン処理粉末、メチルトリクロルシラン、メチルトリアルコキシシラン、ヘキサメチルジシラン、ジメチルジクロルシラン、ジメチルジアルコキシシラン、トリメチルクロルシラン、トリメチルアルコキシシラン等の有機シリル化合物あるいはそれらのフッ素置換体による処理粉末、エチルトリクロルシラン、エチルトリアルコキシシラン、プロピルトリクロルシラン、プロピルトリアルコキシシラン、ヘキシルトリクロルシラン、ヘキシルトリアルコキシシラン、長鎖アルキルトリクロルシラン、長鎖アルキルトリエトキシシラン等の有機変性シランあるいはそれらのフッ素置換体による処理粉末、アミノ変性ポリシロキサン処理粉末、フッ素変性ポリシロキサン処理粉末、フッ化アルキルリン酸処理粉末等が挙げられる。
【００１４】
本発明では、例えば微粒子無水ケイ酸の表面をオルガノシラン系化合物、シリコーン化合物等で覆うことにより調製することができる。具体的には、トリメチルシロキシル化無水ケイ酸、ジメチルシロキシル化無水ケイ酸、オクチルシロキシル化無水ケイ酸、シリコーンオイル処理無水ケイ酸、メチルポリシロキサン処理無水ケイ酸等が例示される。
【００１５】
本発明では、疎水化無水ケイ酸は表面積が６０ｍ2／ｇ以上であることが必要であり、表面積がこれより小さいと、疎水化無水ケイ酸の粒径が大きくなり、（ｃ）成分である水の表面に多量に配向することができず、水を安定に粉末化することが難しくなる。
【００１６】
（ａ）成分の配合量は、その上限が好ましくは２０重量％であり、特には１０重量％である。またその下限が好ましくは２重量％であり、特には３重量％である。配合量が少なすぎると、（ｃ）成分である水を十分に粉末化できず、意図する粉末形態を得ることができなくなるおそれがあり、一方、配合量が多すぎると、多量の水を粉末化することができるようにはなるが、使用時塗擦しても液化が困難となり、官能上好ましくない。
【００１７】
（ｂ）成分は、微生物系水溶性高分子、セルロース系水溶性高分子、アルギン酸系水溶性高分子の中から選ばれる１種または２種以上であり、これらは本発明粉末化粧料の低温保存安定性の向上のためのものである。
【００２３】
（ｂ）成分において、微生物系水溶性高分子としてはキサンタンガム、ヒアルロン酸、デキストラン、サクシノグルカン、カードラン、プルラン等が好ましく用いられる。セルロース系水溶性高分子としてはメチルセルロース、ニトロセルロース、エチルセルロース、メチルヒドロキシプロピルセルロース、ヒドロキシエチルセルロース、セルロース硫酸ナトリウム、ヒドロキシプロピルセルロース、カルボキシメチルセルロースナトリウム（ＣＭＣ）、結晶セルロース、セルロース末等が好ましく用いられる。アルギン酸系水溶性高分子としてはアルギン酸ナトリウム、アルギン酸プロピレングリコールエステル等が好ましく用いられる。
【００２４】
（ｂ）成分は、後述する（ｃ）成分中に溶解した後、（ａ）成分と均一混合して用いる。
【００２５】
（ｂ）成分の配合量は、その上限が好ましくは１０重量％であり、特には５重量％である。またその下限が好ましくは０．００１重量％であり、特には０．１重量％である。配合量が少なすぎると、低温安定性が得られ難くなり、一方、配合量が多すぎると、使用時塗擦しても液化が困難となり、官能上好ましくない。
【００２６】
（ｃ）成分としては、通常の化粧料に用いられる水であれば特に限定することなく用いることができる。
【００２７】
（ｃ）成分の配合量は、本発明化粧料に含まれる他の必須成分、任意添加成分の総配合量の残量分配合することができるが、本発明では、その上限が好ましくは９８重量％であり、特には９０重量％であり、また、その下限が好ましくは７０重量％であり、特には８０重量％である。配合量が少なすぎると塗擦した時に液化が困難となり、一方、配合量が多すぎると粉末化が難しくなり、官能上好ましくない。
【００２８】
上記（ａ）〜（ｃ）成分を必須成分として含有する本発明粉末化粧料は、優れた低温保存安定性を有し、また粉末化が良好で、塗擦時に容易に液化し、良好な使用感を与え、みずみずしさに優れる。
【００２９】
本発明では、上記（ａ）〜（ｃ）成分に加えて、さらに（ｄ）成分として水存在下不安定成分を配合してもよい。
【００３０】
（ｄ）成分としての水存在下不安定成分は、例えば、化粧料、医薬品等に薬剤等として配合され、その機能を発揮するためには水の介在が不可欠である水溶性の成分であるが、水との接触、光、熱等の影響により分解、失活、結晶析出、変退色、異臭を生じる等、水の存在下で不安定で、そのまま水性ないし乳化型化粧料に配合すると分離、凝集、増粘等を生じさせるものをいう。このような成分としては、例えば、美白剤、抗炎症剤、抗菌剤、ホルモン剤、ビタミン類、酵素などの薬剤が挙げられる。具体的には、アルブチン等のハイドロキノン誘導体、コウジ酸、ビタミンＣ、Ｌ−アスコルビン酸−２−グリコシドやリン酸Ｌ−アスコルビルマグネシウム、ビタミンＣジパルミテート、ビタミンＣステアレート等のビタミンＣ誘導体、パントテニールエチルエーテル、トラネキサム酸およびその誘導体、グリチルリチン酸、グリチルリチン酸ジカリウム等のグリチルリチン酸誘導体、レゾルシン、イオウ、サリチル酸およびその誘導体、エストラジオール、ビタミンＢ6、ビタミンＢ6塩酸塩等のビタミンＢ6誘導体、ニコチン酸、ニコチン酸アミド等のニコチン酸誘導体、トリプシンやヒアルロニダーゼ等の酵素などが例示される。
【００３１】
（ｄ）成分の配合量は、その上限が１０重量％が好ましく、より好ましくは７重量％であり、特には５重量％である。またその下限が０．００１重量％が好ましく、より好ましくは０．００５重量％であり、特には０．０１重量％である。配合量が少なすぎると、有効成分たる（ｄ）成分の機能を十分に発揮することが難しく、一方、配合量が必要以上に多すぎても、配合量の増加に見合った効果の増強を見込むことが困難となる。本発明粉末化粧料では、（ｄ）成分を配合した場合でも、これら成分の安定化を図ることができ、それらの機能を十分に発揮し得る。
【００３２】
本発明の粉末化粧料には、上記成分以外に、通常の化粧料に用いられる各種の任意成分、例えば、多価アルコール（グリセリンなど）等の保湿剤、香料、ｐＨ調整剤、防腐剤、紫外線吸収剤、各種粉末、上記以外の水溶性高分子等を、本発明の効果を妨げない範囲で配合することができる。
【００３３】
本発明化粧料は、粉末の化粧料であるが、塗擦により液化するものであり、みずみずしさを有し、きわめて良好な使用性を示し、かつ優れた低温保存安定性を有するとともに、水存在下不安定成分を安定に保持することができる。
【００３４】
本発明の粉末化粧料は、（ａ）成分により、（ｂ）〜（ｃ）成分、さらには（ｄ）成分を粉末化したものであり、塗擦により力を加えると、この吸着状態が破壊され、粉末化されていた（ｂ）〜（ｃ）、（ｄ）成分がにじみ出て液化するとともに、（ｂ）成分の添加効果である使用感触の向上、および（ｄ）成分の有効性が発揮されるものである。
【００３５】
本発明の粉末化粧料は、（ａ）成分により（ｂ）〜（ｃ）成分、（ｄ）成分を粉末化するものであれば特にその製造方法は限定されるものでない。例えば、（ｂ）成分を（ｃ）成分に溶解したもの、あるいはここにさらに（ｄ）成分を溶解したものに（ａ）成分を添加、混合する；（ｃ）成分中に（ｄ）成分を溶解したものに（ｂ）成分を溶解させ、ここに（ａ）成分を添加、混合する、等の製造方法が挙げられるが、これらの例示に限定されるものではない。

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
[0010]
The hydrophobized silicic acid anhydride as the component (a) used in the present invention is obtained by hydrophobizing the surface of fine particle silicic acid anhydride.
[0011]
As a method of hydrophobizing treatment, any method can be used as long as it can impart water repellency to silicic anhydride, and the method is not limited. For example, a gas phase method, a liquid phase method, an autoclave method, a mechanochemical method, etc. A normal surface treatment method can be used.
[0012]
For example, when a hydrophobizing agent is added to the raw material powder for treatment, it may be diluted with an appropriate solvent (dichloromethane, chloroform, hexane, ethanol, xylene, volatile silicone, etc.) or added directly. May be. For mixing and stirring the powder and the treatment agent, a ball mill, a hoger sight ball mill, a vibrating ball mill, an attritor, a pot mill, a rod mill, a pan mill, a homomixer, a homodisper, a Henschel mixer, a nauter mixer, and the like can also be used. In addition to this, by utilizing the activity of the powder surface, a method of polymerizing cyclic organosiloxane on the powder surface at a low temperature of 100 ° C. or less by gas phase reaction (Japanese Patent Publication No. 1-54380), A method of adding a pendant group such as glycerol monoallyl ether to the Si—H portion of the silicone polymer (Japanese Patent Publication No. 1-54381) can also be used.
[0013]
Although it does not specifically limit as a hydrophobizing agent, Fatty acid dextrin processing powder, trimethylsiloxysilicic acid processing powder, fluorine-modified trimethylsiloxysilicic acid processing powder, methylphenylsiloxysilicic acid processing powder, fluorine-modified methylphenylsiloxysilicic acid processing powder Low viscosity to high viscosity oily polysiloxane treated powder such as dimethylpolysiloxane, diphenylpolysiloxane, methylphenylpolysiloxane, gum-like polysiloxane treated powder, methylhydrogenpolysiloxane treated powder, fluorine-modified methylhydrogenpolysiloxane treated powder , Methyltrichlorosilane, methyltrialkoxysilane, hexamethyldisilane, dimethyldichlorosilane, dimethyldialkoxysilane, trimethylchlorosilane, trimethylalkoxysilane, etc. Treatment powder with organic silyl compounds or their fluorine-substituted products, ethyltrichlorosilane, ethyltrialkoxysilane, propyltrichlorosilane, propyltrialkoxysilane, hexyltrichlorosilane, hexyltrialkoxysilane, long-chain alkyltrichlorosilane, long-chain alkyltri Examples thereof include treatment powders with organically modified silanes such as ethoxysilane or fluorine-substituted products thereof, amino-modified polysiloxane-treated powders, fluorine-modified polysiloxane-treated powders, and fluorinated alkyl phosphoric acid-treated powders.

[0015]
In the present invention, the hydrophobized silicic anhydride needs to have a surface area of 60 m 2 / g or more. If the surface area is smaller than this, the particle size of the hydrophobized silicic acid is large and is the component (c). A large amount cannot be oriented on the surface of water, and it becomes difficult to stably powder water.
[0016]
The upper limit of the amount of component (a) is preferably 20% by weight, particularly 10% by weight. The lower limit thereof is preferably 2% by weight, particularly 3% by weight. If the blending amount is too small, the water as component (c) may not be sufficiently pulverized, and the intended powder form may not be obtained. On the other hand, if the blending amount is too large, a large amount of water is powdered. However, liquefaction becomes difficult even if it is rubbed at the time of use, which is not preferable in terms of functionality.
[0017]

If the blending amount is too small, low-temperature stability is difficult to obtain. On the other hand, if the blending amount is too large, liquefaction becomes difficult even if it is applied at the time of use, which is not preferable in terms of functionality.
[0026]
(C) As a component, if it is the water used for normal cosmetics, it can be used without being specifically limited.
[0027]
(C) Although the compounding quantity of a component can be mix | blended with the remainder of the total compounding quantity of the other essential component contained in this invention cosmetics, and an arbitrary addition component, the upper limit is preferably 98 weight in this invention. %, In particular 90% by weight, and its lower limit is preferably 70% by weight, in particular 80% by weight. If the blending amount is too small, liquefaction becomes difficult when coated, while if too blending, powdering becomes difficult, which is not desirable in terms of functionality.
[0028]
The powder cosmetics of the present invention containing the above components (a) to (c) as essential components have excellent low-temperature storage stability, good powdering, easy liquefaction during coating, and good usability Gives excellent freshness.
[0029]
In the present invention, in addition to the components (a) to (c), an unstable component in the presence of water may be added as the component (d).
[0030]
(D) The unstable component in the presence of water as a component is, for example, a water-soluble component that is blended as a drug or the like in cosmetics, pharmaceuticals, etc., and water is indispensable in order to exert its function.

[0031]
The upper limit of the amount of component (d) is preferably 10% by weight, more preferably 7% by weight, and particularly 5% by weight. The lower limit is preferably 0.001% by weight, more preferably 0.005% by weight, and particularly 0.01% by weight. If the blending amount is too small, it is difficult to sufficiently exert the function of the component (d) which is an active ingredient. On the other hand, if the blending amount is more than necessary, an increase in effect commensurate with the increase in blending amount is expected. It becomes difficult. In the powder cosmetic of the present invention, even when the component (d) is blended, these components can be stabilized and their functions can be sufficiently exhibited.
[0032]
In addition to the above components, the powder cosmetic of the present invention includes various optional components used in normal cosmetics, such as humectants such as polyhydric alcohols (such as glycerin), fragrances, pH adjusters, preservatives, ultraviolet rays.
