Description
九州有明海産スサビノリの乾海苔をポルフィラン原料として用いた。乾海苔1kgを沸騰した12kgの精製水にて、95℃、3時間抽出を行った。次いで、抽出残渣を50メッシュのシフターで濾別後、抽出液に対して1%に相当する珪藻土と5%に相当する活性炭を添加して遠心分離(14000rpm、10分)を行い、抽出残物、着色物質及び臭いを完全に除去し、表1に示す精製工程をそれぞれ行った。各工程で得られたポルフィラン溶液は、固形分濃度(Bx.)が3%になるまで濃縮し、それぞれ50mlづつネジ栓付き容器に分注した。オートクレーブ(120℃、20分)後、40℃の環境下で1ヶ月間の保存試験を行った。その結果、工程例1及び2は保存期間中に澱の発生が確認された。工程例3については粘性の低下がみられた。また、工程例5及び6においても僅かな沈降が確認された。それ以外の工程例4、7,8、9においては澱や沈降は全く認められなかった。
実施例1で調製したポルフィラン溶液を固形分濃度(Bx.)から換算して、1.024、0.256、0.064、0.016、0.004及び0.001mg/mlに調製して試験液とした。ヒアルロニダーゼ溶液(330units/mL)0.1mLに試験液を0.2mL加え、37℃で20分間インキュベートした。さらに、酵素活性溶液(2.5mM塩化カルシウム・2H2O)0.2mLを加え、37℃で20分間インキュベートした後、0.08%ヒアルロン酸溶液0.5mLを加え引き続き40分間インキュベートした。酵素活性はMorgan−Elson法にて測定した。
OD[A]:試験液の代わりに精製水を用いて同様に操作を行った溶液の吸光度
OD[B]:酵素溶液の代わりに緩衝液を用いて同様に操作を行った溶液の吸光度
OD[C]:試験液を用いて同様に操作を行った溶液の吸光度
結果を表2に示した。表2に示したようにポルフィランにヒアルロニダーゼ阻害活性が認められ、特に本発明である工程例4〜9に強い阻害活性が認められた。
瀬戸内海産スサビノリの乾海苔をポルフィラン原料として用いた。乾海苔165kgを沸騰した1tの精製水にて、95℃、3時間抽出を行った。次いで、抽出残渣を30メッシュのシフターで濾別後、抽出物に対して1%に相当する珪藻土と5%に相当する活性炭を添加してフィルタープレスを行い、抽残物、着色物質及び臭いを完全に除去した。次に、H+型に置換した強酸性陽イオン交換樹脂ダイヤイオンSK−104を充填した1m2の樹脂塔に抽出液を通液させた。その後、樹脂通過液はアルギニンを用いてpH6.5に調整し、減圧濃縮によりBx.5のポルフィラン溶液とした。
表3に示す各組成に基づき、液体ボディソープを調製した。得られた各液体ボディソープ(1回あたり約6g)を用いて、アトピー性皮膚炎を有する24人のパネルに、毎日、1ヶ月間ボディソープとして使用してもらい、肌の状態について評価してもらった。評価は、1つの液体ボディソープについて8人づつ試験してもらい、評価は下記の項目について5段階の評点評価を実施した。
(1)肌のしっとりさ: 1.かさつく 2.ややかさつく 3.普通 4.ややしっとりする 5.しっとりする
(2)かゆみの程度:1.かゆみが増した 2.変化なし 3.明確ではないがかゆみが減った 4.かゆみが減った 5.かゆみがなくなった
パネラー24名の評点の平均を表5に示した。
表5の処方に従い化粧水を製造した。
(1)肌のしっとりさ: 1.かさつく 2.ややかさつく 3.普通 4.ややしっとりする 5.しっとりする
(2)肌の滑らかさ:1.ざらつく 2.ややざらつく 3.普通 4.やや滑らか 5.滑らか
(3)肌のべたつき:1.べたつく 2.ややべたつく 3.普通 4.ややさっばり 5.さっばり
パネラー10名の評点の平均を表6に示した。
表3から明らかなように、本発明のポルフィランを配合した処方例1の製品は、ポルフィラン無配合の処方例3より優れた保湿性と皮膚平滑性を示した。
実施例1−工程例4のポルフィラン溶液50mlに、天然水150ml、液糖20ml、濃縮グレープフルーツ果汁5ml、香料0.1mlを添加し、ポルフィラン入り清涼飲料水を製造した。
