【発明の属する技術分野】
本発明は、新規な水膨潤性粘土鉱物積層粉体、及びこれを配合した化粧料、特に基盤粉体に対する機能性付与に関する。
【0002】
【従来の技術】
従来、基盤となる粉体の表面上に、異種の粉体粒子や、金属酸化物、有機化合物等を析出することにより、基盤粉体単体では得られない種々の機能性を付与した積層粉体が広く用いられている。例えば、薄片雲母上に二酸化チタンを積層することにより干渉色を発現するパール剤は、このような積層粉体の典型的な例である。
【0003】
一方で、水膨潤性粘土鉱物は、種々の有機化合物と複合体を形成することが知られている。すなわち、水膨潤性の粘土鉱物は、板状の結晶が積み重なり層間にイオンを有した構造をしているため、層間のイオンに分子を吸着させるか、又はこの層間のイオンを他の分子と交換(インターカレート)することによって、容易に複合体とすることができる。水膨潤性粘土鉱物の複合体としては、例えば、カチオン性色素、n−アルキルアミン塩等のカチオン性分子や、アルコール、ケトン、エーテル、ニトリル、水溶性高分子等の極性分子との複合体が知られている。このように、水膨潤性粘土鉱物は、種々の機能性分子との複合体を形成することによって、様々な機能を付与することが可能となる。
【0004】
そして、このような水膨潤性粘土鉱物を基盤粉体表面上に積層し、これを機能性分子接合の足場として用いることにより、粉体への機能付与の可能性が大きく広がると考えられる。しかしながら、粉体表面上に水膨潤性粘土鉱物を積層させた積層粉体については未だ報告されていない。
【0005】
また一方で、近年、盛んに研究されているL-b-L法においては、基盤となる物質と反対の電荷を有する物質を希釈水溶液または分散液中で、静電的な相互作用で連続吸着させることで、比較的簡便にして多層積層構造を構築できるということが知られている。この技術については、1966年にIlerによって反対電荷を有するコロイド粒子を用いて連続交互吸着が起こることが発見され(例えば、非特許文献1参照)、その後、1988年にMalloukらによって、Zr4+とDiphosphonic acidとの交互吸着が報告され(例えば、非特許文献2参照)、さらにDecherらによって、高分子電解質を用いて多層膜フィルムを生成することが報告された(例えば、非特許文献3参照)。そして、これらの発見をきっかけにして、種々のイオン種や荷電したコロイド粒子の積層構造が、今までに報告されている。
【0006】
この中で、1994年には、Kleinfeldらによって高分子電解質と水膨潤性粘土鉱物をシリコンウエハー基板上に交互積層させた多層構造体が報告された(例えば、非特許文献4参照)。さらにその後、Lvovら、Kotovら、Van Duffelら、Rouseら、Kimらが、高分子電解質と水膨潤性粘土鉱物との積層体について報告している(例えば、非特許文献5〜9参照)。

【発明が解決しようとする課題】
しかしながら、これらの高分子電解質と水膨潤性粘土鉱物との多層構造体はすべてシリコンウエハーやマイカなどの基板(cmオーダー)を浸漬するなどの方法で調製されているものであって、粉体を基盤として、粉体表面上に水膨潤性粘土鉱物を積層させた物質はこれまでに報告されていない。
すなわち、本発明は、前述したような現状の課題に鑑み行われたものであり、その目的は、基盤となる粉体表面上に水膨潤性粘土鉱物を積層することによって、粉体表面上への機能性の付与が容易な水膨潤性粘土鉱物積層粉体、及びこれを配合した化粧料を提供することにある。
【0009】
【課題を解決するための手段】
本発明者らは、前述したような現状に鑑み、静電的相互作用を利用して粉体表面上に水膨潤性粘土鉱物を積層した積層粉体を調製する目的で、鋭意研究を行った結果、基盤粉体粒子表面上にイオン性官能基を2以上有するイオン性分子を吸着させることにより、粉体表面の電荷密度を高めるとともに、粉体表面の電荷の正負をコントロールし、さらにこの粉体表面上のイオン電荷と反対の電荷を有する水膨潤性粘土鉱物を吸着させることによって、基盤粉体上に水膨潤性粘土鉱物が安定に積層された積層粉体が得られることを見出し、本発明を完成するに至った。また、この方法によれば、粉体に積層された水膨潤性粘土鉱物表面への機能性分子の吸着や、水膨潤性粘土鉱物層間への機能性分子のインターカレートを行うことによって、粉体への新たな機能の付与を容易に行うことが可能となる。
【0010】

1.水膨潤性粘土鉱物積層粉体の調製
本発明者らは、まず最初に、合成フッ素金雲母上に、高分子電解質としてポリジアリルジメチルアンモニウムクロライド(PDDA)、ポリスチレンスルホン酸ナトリウム(PSS)、水膨潤性粘土鉱物としてラポナイトを用い、それぞれの表面電荷又はイオン電荷が正負交互となるような積層粉体の調製を試み、生成物についての評価、検討を行った。
【0028】
実施例1.ラポナイト /PDDA/ 合成フッ素金雲母積層粉体
負に荷電している平均粒子径30μmの合成フッ素金雲母(トピー工業社製)を、カチオン性の高分子電解質であるポリジアリルジメチルアンモニウムクロライド(PDDA)(Aldrich製 MW:<200000)1%水溶液中に浸漬させることにより、PDDAをフッ素金雲母上に吸着させ、PDDA/合成フッ素金雲母積層粉体を調製した。なお、得られた積層粉体は、PDDA吸着後、水で十分に洗浄した。
【0029】
つづいて、負に荷電している水膨潤性粘土鉱物であるラポナイトXLG(ラポルテ社製)をゲル化しない程度の濃度(<2%)で水中に分散させ、透明な分散液が得られるまで、攪拌混合しラポナイト水分散液を調整した。
得られたラポナイト水分散液中に、上記PDDA/合成フッ素金雲母積層体を、ラポナイト:PDDA/合成フッ素金雲母積層体の質量比が1:1の割合となるようにして加え、攪拌混合し、その後、ろ過、洗浄、乾燥を行い、ラポナイト/PDDA/合成フッ素金雲母積層粉体を得た。
【0030】
実施例2 ラポナイト /PDDA/PSS/PDDA/ 合成フッ素金雲母積層粉体
実施例1と同様にして、PDDAをフッ素金雲母上に吸着させて得られたPDDA/合成フッ素金雲母積層粉体を、アニオン性の高分子電解質であるポリスチレンスルホン酸ナトリウム(PSS)(Aldrich製 MW:70000)1%水溶液に浸漬させることによって、粉体表面にPSSを吸着させ、さらに上記PDDAの吸着操作を再び行うことによって、PDDA/PSS/PDDA/合成フッ素金雲母積層粉体を調整した。なお、得られた積層粉体は、各高分子電解質を吸着後、水で十分に洗浄してから、次の操作を行った。
【0031】
つづいて、実施例1と同様にして得られたラポナイト水分散液中に、上記PDDA/PSS/PDDA/合成フッ素金雲母積層粉体をラポナイト:PDDA/PSS/PDDA/合成フッ素金雲母積層粉体の質量比が1:1の割合となるようにして加え、攪拌混合し、その後、ろ過、洗浄、乾燥を行い、ラポナイト/PDDA/PSS/PDDA/合成フッ素金雲母積層粉体を得た。
【0032】
以上のようにして得られた実施例1,2の各積層粉体について、CHN元素分析、ζ電位測定、DFM測定により、評価を行った。なお、各評価における分析及び測定に際し、用いた装置及び条件は以下の通りである。
【0033】
CHN元素分析:2400II CHNS/O(パーキンエルマー社製)
ζ電位測定:LEZA60(大塚電子社製) 移動相溶媒:0.1M NaCl水溶液
DFM測定:SPA400/3800N(セイコーインスツルメント社製)
カンチレバー:DF-20(セイコーインスツルメント社製)(SiN製 ばね乗数:20N/m)
【0034】
実施例1、2の積層粉体の各処理段階における、CHN元素分析により得られたC%、及びζ電位を表1に、実施例1の積層粉体の各処理段階におけるDFM像を図1〜3に示す。
【表1】
【0035】
表1のCHN元素分析の結果に示されるように、PDDA吸着後、PSS/PDDA吸着後、PDDA/PSS/PDDA吸着後の何れの場合も炭素量は増大しており、高分子電解質が吸着していることが確認された。また、ラポナイト処理後は、処理前と比較して炭素量はほとんど変化していないことから、ラポナイト処理に際して高分子電解質の脱着が起こっていないことが確認された。
【0036】
また、表1のζ電位測定結果に示されるように、未処理の合成フッ素金雲母表面のζ電位は-26mV程度であり、表面は負に帯電している。これに対して、PDDA/合成フッ素金雲母では表面がポリカチオンで覆われるため、表面のζ電位は+28mV程度となり表面が正に帯電している。さらに、ラポナイト/PDDA/合成フッ素金雲母では表面のζ電位は-13mV程度に変化しており、表面電位が負であるラポナイトが積層されていることが確認される。同様にラポナイト/PDDA/PSS/PDDA/合成フッ素金雲母においても、表面ζ電位は-15mV程度であり、表面がラポナイトで積層されていることが確認される。
【0037】
図1〜3に示されているように、DFM測定による各種粉体の表面形状観察を行ったところ、未処理の合成フッ素金雲母(図1)と、PDDA/合成フッ素金雲母(図2)の表面の形状に大きな違いは無い。一方で、ラポナイト/PDDA/合成フッ素金雲母(図3)では、表面が20〜40nm程度の粒子で隙間無く覆われていることが確認された。また、高さ方向のラフネスも5〜10nm程度であり、凹凸無く非常に均一に積層されていることがわかる。なお、ラポナイト/PDDA/PSS/PDDA/合成フッ素金雲母に関しても、同様のDFM像が観察された。これにより、基盤となる粉体の表面状が水膨潤性粘土鉱物により均一に覆われた、新規な水膨潤性粘土鉱物積層粉体が調製されたことが確認された。
【0038】
2.積層粉体上へのカチオン性機能性分子の吸着
つづいて、本発明者らは、カチオン性機能分子としてジメチルジステアリルアンモニウムクロリド(2C18)を用い、上記のようにして得られた積層粉体表面上への吸着を試み、生成物についての評価、検討を行った。
【0039】
実施例3 2C18/ ラポナイト /PDDA/ 合成フッ素金雲母
実施例1のラポナイト/PDDA/合成フッ素金雲母を、80℃に加温した5mMジメチルジステアリルアンモニウムクロライド(2C18)水溶液中に添加(質量比でラポナイト/PDDA/合成フッ素金雲母:2C18=50:1)し、1時間攪拌混合した。その後、80℃の水にて水洗した後、ろ過、乾燥を行い2C18/ラポナイト/PDDA/合成フッ素金雲母を得た。
【0040】
以上のようにして得られた実施例3の積層粉体に関して、CHN元素分析、水接触角測定、化粧品専門パネルによる官能評価を、積層粉体単体で、及びそれを配合したパウダリーファンデーションの系で行った。パウダリーファンデーションの配合処方を表3に、粉体単体及び化粧料配合時の評価結果を表2及び表4に示す。なお、官能評価の評価内容は以下の通りである。

化粧料配合評価
【表4】
上記表2より、2C18による表面処理前後で、CHN元素分析より得られたC%の値が1%程度増加していた。また、水接触角測定からは、表面処理前では粉末表面が親水性を示しているが、2C18による表面処理後では、撥水性を示していた。 これらのことから、ラポナイトが均一被覆されていることにより、負電荷及びカチオン交換サイトを有している表面に、カチオン性の機能性分子であるジメチルジステアリルアンモニウムが吸着していることが確認された。また、化粧品専門パネルによる粉体単体の評価では、2C18処理後では、処理前と比較して、すべり感や滑らかさが改善されていることがわかった。また、上記表4より、ファンデーションの系での評価でも、配合実施例1は比較配合例1と比較して、すべり感や滑らかさが向上しており、また表面が撥水性を示すことに起因すると考えられる化粧もち持続効果も向上した。
【0046】

さらに、本発明者らは、機能性分子として、水溶性高分子であるポリビニルピロリドン(PVP)、及び多価アルコールであるグリセリンをインターカレートした水膨潤性粘土鉱物を調製し、これらを用いて前記実施例と同様に積層粉体の調製を試み、生成物についての評価、検討を行った。

なお、以上のようにして得られたPVP/ラポナイト複合粉体、及びグリセリン/ラポナイト複合粉体について、PVP又はグリセリンがラポナイト層間にインターカレートされているかどうか、XRD測定による確認を行った。
・XRD測定
ラポナイトXLGのXRD測定より、ラポナイトの(001)に起因する回折ピークが14.5Åに見られたのに対して、PVP/ラポナイトのXRD測定では、(001)に起因するピークが29.0Åに見られた。このことから、ラポナイトの基本面間隔が約14.5Å広がっており、ラポナイトの層間にPVPがインターカレートしていることが確認された。同様に、グリセリン/ラポナイトに関しても、基本面間隔が約4.0Å広がっており、グリセリンがラポナイト層間にインターカレートしていることが確認された。
【0050】
実施例4 (PVP/ ラポナイト )/PDDA/ 白雲母
基盤粉体として白雲母を用い、実施例1と同様にして、10%のPDDA水溶液中に白雲母を重量比でPDDA:白雲母=10:1になるような割合で添加し、攪拌混合後、ろ過洗浄を行いPDDA/白雲母を得た。なお、得られた白雲母は、CHN元素分析よりC%が0.45%となり、ζ電位は+38mVとなり、白雲母表面を十分な量のPDDAが吸着していることを確認した。このPDDA/白雲母を、上記PVP/ラポナイト複合粉体がゲル化しない程度の濃度に調整した水分散体に添加し、攪拌混合後、ろ過、水洗を行い、(PVP/ラポナイト)/PDDA/白雲母を得た。
【0051】
実施例5 ( グリセリン / ラポナイト )/PDDA/ 白雲母

BACKGROUND OF THE INVENTION
The present invention relates to a novel water-swellable clay mineral laminated powder, and a functional imparting to a cosmetic, particularly a base powder, containing the same.
[0002]
[Prior art]
Conventionally, laminated powders with various functionalities that cannot be obtained with a single base powder by depositing different kinds of powder particles, metal oxides, organic compounds, etc. on the surface of the base powder. Is widely used. For example, a pearling agent that expresses an interference color by laminating titanium dioxide on lamellar mica is a typical example of such a laminated powder.
[0003]
On the other hand, it is known that water-swellable clay minerals form complexes with various organic compounds. That is, the water-swellable clay mineral has a structure in which plate-like crystals are stacked and have ions between layers, so that molecules are adsorbed by ions between layers or ions in this layer are exchanged with other molecules. By (intercalating), it can be easily made into a composite. As a complex of water-swellable clay mineral, for example, a complex with a cationic molecule such as a cationic dye, an n-alkylamine salt, or a polar molecule such as alcohol, ketone, ether, nitrile or water-soluble polymer. Are known. Thus, the water-swellable clay mineral can impart various functions by forming a complex with various functional molecules.
[0004]
Then, by laminating such a water-swellable clay mineral on the surface of the base powder and using it as a scaffold for functional molecular bonding, it is considered that the possibility of imparting a function to the powder is greatly expanded. However, a laminated powder obtained by laminating a water-swellable clay mineral on the powder surface has not yet been reported.
[0005]
On the other hand, in the LbL method that has been actively studied in recent years, a substance having a charge opposite to that of the base substance is continuously adsorbed by electrostatic interaction in a dilute aqueous solution or dispersion. It is known that a multilayer laminated structure can be constructed relatively easily. As for this technique, it was discovered in 1966 that continuous alternating adsorption occurs using colloidal particles having an opposite charge by Iler (see, for example, Non-Patent Document 1), and then in 1988 by Mallouk et al., Zr4+And diphosphonic acid were reported to be alternately adsorbed (see, for example, Non-Patent Document 2), and Decher et al. Reported to produce a multilayer film using a polymer electrolyte (for example, see Non-Patent Document 3). ). Based on these findings, various ionic species and stacked structures of charged colloidal particles have been reported so far.
[0006]
Among them, in 1994, Kleinfeld et al. Reported a multilayer structure in which a polymer electrolyte and a water-swellable clay mineral were alternately laminated on a silicon wafer substrate (for example, see Non-Patent Document 4). Furthermore, Lvov et al., Kotov et al., Van Duffel et al., Rouse et al., Kim et al. Reported on a laminate of a polymer electrolyte and a water-swellable clay mineral (for example, see Non-Patent Documents 5 to 9).

[Problems to be solved by the invention]
However, the multilayer structures of these polymer electrolytes and water-swellable clay minerals are all prepared by a method such as dipping a substrate (cm order) such as silicon wafer or mica. No material has been reported so far in which a water-swellable clay mineral is laminated on the powder surface.
That is, the present invention has been made in view of the above-mentioned problems as described above. The purpose of the present invention is to laminate a water-swellable clay mineral on the surface of the powder as a base, and thereby onto the surface of the powder. It is an object of the present invention to provide a water-swellable clay mineral laminated powder that can be easily imparted with the functionality described above, and a cosmetic containing the same.
[0009]
[Means for Solving the Problems]
In view of the current situation as described above, the present inventors have conducted intensive research for the purpose of preparing a laminated powder obtained by laminating a water-swellable clay mineral on a powder surface using electrostatic interaction. As a result, by adsorbing ionic molecules having two or more ionic functional groups on the surface of the base powder particles, the charge density on the powder surface is increased and the positive / negative of the charge on the powder surface is controlled. It has been found that by adsorbing a water-swellable clay mineral having a charge opposite to the ionic charge on the body surface, a laminated powder in which the water-swellable clay mineral is stably laminated on the base powder can be obtained. The invention has been completed. In addition, according to this method, by adsorbing functional molecules on the surface of the water-swellable clay mineral laminated on the powder and intercalating the functional molecules between the water-swellable clay mineral layers, It becomes possible to easily give a new function to the body.
[0010]
That is, the first subject of the present invention is that a layer made of ionic molecules having two or more ionic functional groups is laminated on the surface of the powder particles as a base, and a layer made of water-swellable clay mineral is formed on the layer. A water-swellable clay mineral laminated powder, characterized in that it is a laminated powder that is laminated continuously so that the surface charge or ionic charge in each layer alternates between positive and negative.
[0011]
In the laminated powder, the ionic molecule is preferably a polymer electrolyte. In the laminated powder, it is preferable that the primary particle diameter of the water-swellable clay mineral is 0.5 μm or less. In the laminated powder, it is preferable that the average particle diameter of the base powder is 0.1 to 1000 μm.In the laminated powder, the water-swellable clay mineral is preferably Laponite (trademark; sodium silicate, lithium, magnesium hydrate).In the laminated powder, a functional molecule having a charge opposite to the charge of the water-swellable clay mineral surface or ionic molecules present on the outermost surface is adsorbed on the outermost surface of the laminated powder. Is preferred. In the laminated powder, the outermost surface of the laminated powder is a water-swellable clay mineral, and a cationic functional molecule is adsorbed on an ion exchange group on the surface of the water-swellable clay mineral present on the outermost surface. Is preferred. In the laminated powder, the cationic functional molecule is preferably an alkyl ammonium salt. Moreover, in the laminated powder, it is preferable that the adsorption amount of the cationic functional molecule is 0.01 to 10%.
[0012]

Attempts were made to prepare laminated powders with alternating surface charge or ionic charge, and the products were evaluated and examined.
[0028]
Example 1. Laponite / PDDA / Synthetic fluorophlogopite laminated powder
A negatively charged synthetic fluorine phlogopite with an average particle size of 30μm (Topy Industries, Ltd.) is a cationic polyelectrolyte polydiallyldimethylammonium chloride (PDDA) (Aldrich MW: <200000) 1% aqueous solution PDDA / synthetic fluorine phlogopite laminated powder was prepared by adsorbing PDDA on fluorine phlogopite by immersing in it. The obtained laminated powder was thoroughly washed with water after PDDA adsorption.

Next, Laponite XLG (manufactured by Laporte), a negatively charged water-swelling clay mineral, is dispersed in water at a concentration (<2%) that does not gel, until a transparent dispersion is obtained. The mixture was stirred and mixed to prepare a Laponite aqueous dispersion.
The above-mentioned PDDA / synthetic fluorophlogopite laminate is added to the resulting laponite aqueous dispersion so that the mass ratio of laponite: PDDA / synthetic fluorophlogopite laminate is 1: 1, and the mixture is stirred and mixed. Thereafter, filtration, washing and drying were performed to obtain a laponite / PDDA / synthetic fluorophlogopite laminated powder.
[0030]
Example 2 Laponite / PDDA / PSS / PDDA / Synthetic fluorophlogopite laminated powder
In the same manner as in Example 1, PDDA / synthetic fluorine phlogopite laminated powder obtained by adsorbing PDDA on fluorine phlogopite was used as anionic polymer electrolyte sodium polystyrene sulfonate (PSS) (manufactured by Aldrich).
