コエンザイムQ10 5mgをアセトン1mLにとかした。この混合溶液を500rpmで撹拌される1%システイン水溶液30mLに速く一括添加し、分散させて、コエンザイムQ10を可溶化させた後、6時間500rpmで撹拌させて、溶媒を除去した。コエンザイムQ10ナノ粒子が分散された水溶液は、半透明の黄色を示した。可溶化されたコエンザイムQ10ナノ粒子水溶液は、4℃に保管した。
コエンザイムQ10 5mgをN−メチルピロリドン1mLにとかした。この混合溶液を500rpmで撹拌される1%セリン水溶液30mLに速く一括添加し、分散させて、コエンザイムQ10を可溶化させた後、−20℃で凍結させて、凍結乾燥装置(EYELA FDU−2100、EYELA、日本国)を利用して24時間減圧凍結乾燥し、薄い黄色の粉末を得た。その後、粉末を滅菌された蒸留水に再分散させて、コエンザイムQ10ナノ粒子が分散された水溶液が半透明の黄色を示すことを観察した。可溶化されたコエンザイムQ10ナノ粒子水溶液は、4℃に保管した。
コエンザイムQ10 10mgをN−メチルピロリドン1mLにとかした。この混合溶液を500rpmで撹拌される1%魚の皮膚から抽出したゼラチン水溶液30mLに速く一括添加し、分散させて、コエンザイムQ10を可溶化させた。その後、分画分子量(Molecular Weight of Cut-Off)分離膜フィルターを利用して分子量が低い有機溶媒を除去し、コエンザイムQ10ナノ粒子が分散された水溶液は、半透明の黄色を示した。可溶化されたコエンザイムQ10ナノ粒子水溶液は、4℃に保管した。
豚の皮膚から抽出したゼラチンを使用したことを除いて、実施例3と同一である。
牛の皮膚から抽出したゼラチンを使用したことを除いて、実施例3と同一である。
卵白アルブミンを使用したことを除いて、実施例3と同一である。
牛血清アルブミンを使用したことを除いて、実施例3と同一である。
ヒト血清アルブミンを使用したことを除いて、実施例3と同一である。
図9の1)は、コエンザイムQ10粉末、2)は、コエンザイムQ10粉末を水に分散させた時、上層として相分離された水溶液、3)は、本発明の実施例7のコエンザイムQ10ナノ粒子水溶液の写真を示すものである。
実施例7で製造されたナノ粒子の形態を観察するために、タンパク質により可溶化されたナノ粒子を遠心分離方法を利用して4℃で17000rpmで3回洗浄した後、試験片を製作し、透過電子顕微鏡(FE−TEM、JEOL、日本国)を利用して観察した。
コエンザイムQ10ナノ粒子水溶液の長期間の安定性を調査するために、実施例8の製造方法を利用して製造された半透明の黄色水溶液を3群で製造し、UVが遮断された条件で5ヶ月間室温で放置し、1ヶ月単位で平均粒径を測定し、分散安定性を調査した。上記実験は、滅菌された条件で行い、その他、防腐剤及び添加剤は使用しなかった。
下記表2の組成で透明ゲル形態の可溶化剤形で製造例1を製造した。剤形の粘度は、約4,000cpsである。一方、粘度は、Brookfield(LVDVII+)を利用して30℃、12rpmで測定した。
下記表3の組成で不透明ゲル形態の可溶化剤形で製造例2を製造した。それぞれの油相と水相を70℃で完全溶解させ、7,000rpmで5分間乳化させて、不透明ゲル形態のローションを製造した。ローションの粘度は、約2,500cpsである。一方、粘度は、Brookfield(LVDVII+)を利用して30℃、12rpmで測定した。
下記表4の組成でクリーム剤形の製造例3を製造した。製造過程は、上記製造例2と同一である。
