Description
過酸化ベンゾイルの湿潤製粉において直面する1つの困難は、上述したように、過酸化ベンゾイルが非常に疎水性であり、水で濡れることに抵抗することである。さらに、過酸化ベンゾイル粒子間の強い引力は、製造方法および最終医薬製剤の品質を危うくする凝集の問題を生じさせる。界面活性剤は、この目的および過酸化ベンゾイルの安定的な非凝集のミクロ懸濁液を維持するために、Cox、YoungおよびKleinの各特許で開示されたように利用されたが、界面活性剤は、損傷または病気の皮膚を刺激する傾向のために好適ではない。したがって、過酸化ベンゾイルが、直ちに湿潤されることができ、懸濁液、親水性または水性流体において好適に置かれ、好適には界面活性剤を使用しない方法は、大きな利点である。
この出願の発明に関連する先行技術文献情報としては、以下のものがある(国際出願日以降国際段階で引用された文献及び他国に国内移行した際に引用された文献を含む)。

過酸化ベンゾイルの湿潤性の研究は以下の様に行われた。過酸化ベンゾイル粉末の1.5グラムは約5cmの直径を有するガラスビーカーに含まれる4つのテスト流体の表面に広げられた。4つのテスト流体は、72.0ダイン/cmの表面張力を有する精製水30ml(試料A)、7.5%エタノールおよび51.4ダイン/cmの表面張力を有する95%精製水からなる流体30ml(試料B)、20%ポリエチレングリコール(PEG200)および51.9ダイン/cmの表面張力を有する80%精製水からなる流体30ml(試料C)、および、20%ジメチルイソソルバイド(DMI)および50.1ダイン/cmの表面張力を有する80%精製水からなる流体30ml(試料D)である。それぞれのビーカーの底に12mm×8mmの磁気攪拌棒をおいた。各流体は、表面に過酸化ベンゾイル粉末を有し、1200rpmで撹拌された。室温での撹拌の5〜10分後、試料は過酸化ベンゾイルの湿潤度合いにおいて視覚的に調べられた。試料Aにおける湿潤の視覚的証拠はごくわずかであるか、ないかであり、過酸化ベンゾイルの湿潤は不十分であった。試料B、CおよびDのそれぞれにおける過酸化ベンゾイルの湿潤は、過酸化ベンゾイル粉末の少なくとも90%の湿潤の視覚的証拠により、良好であると決定された。
水を含む流体の表面張力は、水において様々な水溶性有機溶剤の濃度と混合する前後で決定された。本研究は室温で実行され、その結果は表3に示されている。表面張力における値はダイン/cmである。
懸濁液は、9.4% w/wプロピレングリコールおよび90.6% w/wの水を含む分散流体を利用する24.8% w/w含水過酸化ベンゾイルを含んで調製される。ステンレススチールタンク内で、36kgの精製水と3.75kgのプロピレングリコールが結合される。結合は、混合物を形成するためにプロペラミキサーによって撹拌された。混合の間、13.12kgの含水過酸化ベンゾイル(74.5%過酸化ベンゾイル)が加えられた。室温で過酸化ベンゾイル粉末を湿潤および分散させるため、および、過酸化ベンゾイル懸濁液を得るため、1450rpmで約10分間、混合は続けられた。
