Description
プロピレングリコールの含有量は液剤の全量に対して、6~22w/v%であり、好ましくは11~18w/v%、より好ましくは12~16w/v%である。プロピレングリコールとミノキシジルは、この含量範囲であればミノキシジルの結晶析出、及び経時的な液剤の着色が十分に抑制される。また、この含量範囲であれば、ベトツキ感がなく、好適な粘性や経皮吸収性を有する。
pH調整剤は本発明の液剤のpHを6.0~6.5に調整するために用いる。pH調整剤の含量は、液剤の全量に対して、0.02~0.5w/v%である。pHが6.5より高いとミノキシジルが溶解しにくく、pHが6.0未満ではミノキシジルが低温で析出する問題がある。
調製した組成物の目視観察により、澄明、懸濁(不溶物の存在)、凝固(ゲル化)などを観察した。
20mLガラス製のビンに入れて密栓し、50℃で1週間保持し、着色を観察した。室温保存品と比較し、目視で褐色の増加が認められない場合を-、わずかな着色増加が認められた場合を+、より強い着色が認められた場合を++とした。
20mLガラス製のビンに入れて密栓し、-18℃で1週間保持し、固形分析出を観察した。目視で固形分析出が認められない場合を-、わずかな固形分析出が認められた場合を+、固形分析出がより強く認められた場合を++とした。
5名の試験者が、手の甲に溶液1mLを滴下して液のタレ具合、反対側の手でその溶液を伸ばしたときの伸び及びなじみの良さをみた。5名中3名以上が使用上の問題がないと判定した場合を〇、5名中1~2名が使用上の問題がないと判定した場合を△、使用上の問題がないと判定した評価者が無かった場合を×とした。
