Definitions
- the present invention relates to a vesicle composition, a skin external preparation containing the composition, and a cosmetic.
- Vesicles (closed vesicles having a bilayer structure formed by an amphiphile) are able to encapsulate active ingredients because of this specific structure, and thus are attracting attention as carriers for drug delivery systems and the like. .

これに対し、後記実施例に示すように、リン脂質を使用しなくとも本発明の上記成分を使用すれば、新規ベシクルを形成することが可能である。当該形成されたベシクルは、ベシクル内部に電解質や難溶性物質等を配合することができるので、生体内での有効成分の搬送や肌へのこのような有効成分の浸透貯留性を向上させること等も可能である。
しかも、本発明のベシクルは、熱力学的に安定であり、また内部及び外部に電解質が存在する場合(例えば、塩基性薬・酸性薬、高伝導性溶液、アルカリ溶液、酸溶液等の共存)でも安定的である。すなわち、経時安定性に非常に優れている。更に、膜流動性にも優れており、この膜流動性に優れていることによって有効成分を肌へ浸透貯留させることが可能となり、有効成分の効果を良好にする。
また、ベシクル組成物の電気伝導度(20℃)は通常0.001S/m程度未満であるが、0.001~3S/mの範囲内、より0.001~1S/m、更に0.001~0.5S/mと電解質を含有させた場合であっても、本発明のベシクル組成物は、従来のベシクル組成物と比較し、ベシクルの経時安定性が高い点で有利である。当該電気伝導度は、20℃にて導電率計を用いて測定して行ったものである。
また、本発明のベシクル組成物を、上述の種々の用途の製品に含有させてもよく、このときの本発明のベシクル組成物の含有量は特に限定されないが、製品中、1.0~90質量%とするのが好ましく、より3.0~50質量%とするのが好ましい。また、前記製品中のpHや電気伝導度の範囲は上述の範囲内であれば、ベシクルの経時安定性の点から有利である。

表1の実施例1~15の欄に示す各成分を用いて下記の製法によりベシクル組成物を調製した。
また、実施例13のベシクル組成物(図3のサンプルB)は、実施例2のベシクル組成物(図3のサンプルA)の成分(A)ポリオキシエチレン(5モル)フィトステロール、成分(B)バチルアルコール及び成分(C)コレステロールの含有量を代えた以外は実施例2と同様にして調製した。
工程1:成分1~17のうちから選ばれた成分を95℃に加熱して溶液とした。
工程2:工程1で得られた溶液に、75℃に保持しながら精製水を添加し、ディスパミキサーにて、分散液を得た。
工程3:工程2で得られた分散液を40℃まで徐々冷却して、実施例1~15の各ベシクル組成物を得た。
表2の試験例1~3の欄に示すように、上記製造工程1~3で得られたベシクル組成物に成分18~20から選ばれる成分を添加して、試験例1~3の各ベシクル組成物を調製した。
試験例1のベシクル組成物の電気伝導度(20℃)は、0.36(S/m)であった。
試験例2のベシクル組成物のpH(20℃)は、3.2であり、電気伝導度(20℃)は、0.07(S/m)であった。
試験例3のベシクル組成物のpH(20℃)は、9.7であり、電気伝導度(20℃)は、0.03(S/m)であった。
表2の比較例1~7の欄に示す各成分を用いて、上記実施例1~15のベシクル組成物の製法と同様にして、比較例1~7の各ベシクル組成物を調製した。
一次スクリーニングとして偏光顕微鏡(オリンパス社製)を用いて、直交ニコル下にて製造直後及び40℃2週間静置後のサンプルを観察し、上記各ベシクル組成物のマルテーゼクロス像の有無を確認した。この判定基準を下記に、その結果を表1に示す。
また、上記各ベシクル組成物を顕微鏡観察にて、40℃、2週間静置後の成分の析出の有無を確認した。
◎:マルテーゼクロス像が多数確認できる
○:マルテーゼクロス像が多数存在しないが容易に確認できる
×:マルテーゼクロス像が確認できない
(ロ)判定基準:析出
◎:沈殿が全くみられない
○:顕微鏡にて確認されるが問題にならない程度
×:沈殿がかなり見られ、問題がある
また、透過型電子顕微鏡(TEM)(リンタングステン酸コーティング)を用いてマルチラメラベシクルの形成の有無を確認した。図2に示すように、TEM観察においても、多重層構造を示すマルチラメラベシクル像が観察された。
実施例2及び13のベシクル組成物について、熱流速型示差走査熱量計(SIIナノテクノロジー社製)を用いて示差走査熱量(DSC)測定を行った。実施例2をサンプルA、実施例13をサンプルBと表記した。
実施例2及び13のベシクル組成物では40~50℃付近に表れるゲル液晶転移温度に相当する吸熱ピークが消失しており、熱力学的に安定な構造を有していることが示唆された。
以上のことから、本発明のベシクル(実施例1~15のベシクル組成物及び試験例1~3のベシクル組成物)は、熱力学的に安定であることが示唆された。
試験例1~3のベシクル組成物について、上記(イ)(ロ)評価基準にて試験を行った結果を表1に示す。
また、実施例2のベシクル組成物中に、0.5質量%になるようにNaClを添加し、50℃で14日間の経時安定性を透過率にて検討した結果、ほとんど透過率の変化がみられず、経時安定性が良好であった。
また、試験例2及び3のように、電解質であるL-アスコルビン酸2-グルコシド、クエン酸及び水酸化ナトリウムを含有させても、経時安定性は良好であった。
以上のことから、本発明のベシクル(実施例1~15のベシクル組成物及び試験例1~3のベシクル組成物)は、電解質共存下、酸性やアルカリ領域下においても優れた経時安定性を有していた。
実施例2のベシクル組成物の膜流動性の評価を、蛍光偏光度測定法を用いて行った。
また、比較例6及び7のベシクル組成物を製造する際に、L-アスコルビン酸2-グルコシド及び水酸化ナトリウムを含有させずに作製したものを、比較例8及び9のベシクル組成物とし、同様に膜流動性の評価を行った。
このとき、NaCl濃度が0、0.3、0.5%となるように、各サンプルを調整した。
このとき蛍光偏光度に用いた装置は、蛍光光度計RF-5300(島津製作所社製)
試薬は、親油性蛍光プローブとしてDPH(1,6‐ジフェニル‐1,3,5‐ヘキサトリエン)(励起光360nm、蛍光検出430nm)、親水性蛍光プローブとしてANS(1-アニリノナフタレン-8-スルホン酸)(励起光380nm、蛍光検出465nm)を用いた。蛍光偏光度は以下の算出にて求め、また、図4の左側の目盛軸にてプロットした(DPH:図4にて□。ANS:図4にて◇)。さらに、DPHを用いた際の蛍光偏光度(PDPH)とANSを用いた際の蛍光偏光度(PANS)の比率(PANS/PDPH)を求め、図4の右側の目盛軸にてプロットした(図4にて△)。
図4に示すように、本発明のベシクル組成物である実施例2は、電解質であるNaClを添加してもPANS/PDPHがほぼ一定であり、親水基と親油基の膜流動性のバランスが維持されていた。
一方、図5~6に示すように、比較例8~9のベシクル組成物は、PANS/PDPHが大きく変動している。これは電解質であるNaClを添加することで親水基と親油基の膜流動性のバランスが大きく崩れており、実施例より劣っているものである。
本発明のベシクル粒子の膜流動性のバランスは維持されていたので、本発明のベシクルを用いれば有効成分を肌へ浸透貯留させることが可能となり、有効成分の効果を良好にすることが期待できる。
よって、本発明のベシクル組成物は、幅広い条件下において有効成分を内包できる可能性を有した製剤であると考えられる。
また、原材料に実質的にレシチン等のリン脂質を使用しなくとも、少なくともステロール骨格を有する非イオン性界面活性剤及びモノアルキルグリセリルエーテルを使用すればベシクルを形成できることも確認できた。
