Description
CMC:所定のナトリウムカルボキシメチルセルロース、CRT−30 PA、DS=0.9、ザ・ダウ・ケミカル・カンパニー(米国ミシガン州ミッドランド)製の品番7M650。

ポリソルベート80:(Tween 80)所定の酵素グレード、フィッシャー・サイエンティフィック(Fisher Scientific)製の943317。
錠剤:ザ・ダウ・ケミカル・カンパニー製の所定のプラセボ錠剤(100gの赤色カプレットコア、493gの白色楕円形錠剤、6.5gの白色ディスク)。
被膜の作製:一定温度(22℃)及び相対湿度(50%RH)の環境内ですべての被膜の作製及び貯蔵を完了する。1mmギャップのキャスティング(ドローダウン)バーの端部付近に20質量%溶液をゆっくり注ぎ、次に、気泡及び欠陥を最低限に抑えるために溶液を徐々に引きのばすことによりガラス板上に湿潤被膜(1mm)を手動で引きのばす。プレート上の被膜を2日間乾燥させ、プレートからそれらを剥離し、さらに1日間の被膜をアニールする。アニールした被膜について被膜特性を測定する。好ましくは、任意のサンプル間の変動を最低限にするために被膜剥離から4日間以内に全ての被膜の試験を完了する。被膜を試験しないときは、被膜を、紙のシートの間で、一定の温度と相対湿度で保管する。
被膜曇り度試験法:作製した被膜の曇り度を、BYK Gardner(米国メリーランド州コロンビア製、カタログ番号4725)により測定する。曇り度及び透過率の両方の読み取り値を百分率として記録する。4つの読み取り値の平均値を記録する。
パーセント被膜曇り度及び明澄度値を被膜のミリメートル単位の厚さで割ってパーセント規格化被膜曇り度及びパーセント規格化被膜明澄度を得る。
(a)100%CMCの被膜、この被膜は、14%/mmの規格化された被膜曇り度、472%/mmの規格化された被膜明澄度、及び12×10−7g/Pa・h・mの平均WVT透過率を有する;
(b)100%ゴーセノールEG−05Pの被膜、この被膜は粘着性である(後述の錠剤被覆法に従って被覆した場合に凝集した部分は13質量%);
(c)100%ゴーセノールEG−40P(86.5モル%〜89.0モル%のケン化度及び20℃で4wt/vol%水溶液として測定される40mPa・s〜46mPa・sの動的粘度を有する高粘度PVOH)の被膜、この被膜は粘着性であり、被膜(b)の規格化された被膜曇り度及び規格化された被膜明澄度と比べて実質的に高い規格化された被膜曇り度及び規格化された被膜明澄度を有する;及び
(d)50:50ゴーセノールEG−05P/CMCの被膜、この被膜は7×10−7g/Pa・h・mの平均水透過率を有する。
実施例1〜6:LV−PVOH及びCMCのタルクフリー組成物。以下の表1に従って、8g〜25g(例えば10g)のゴーセノールEG−05P(LV−PVOH)及びCMCと必要に応じて可塑剤を脱イオン(DI)水(例えば、100グラム)中に混合しながら溶解させて実施例1〜6の各々について溶液(固形分4質量%〜15質量%)としてタルクフリー組成物を得た。溶液の一部から水を蒸発させて、実施例1に示したとおりゴーセノールEG−05PのLV−PVOH、CMC、及び必要に応じて可塑剤を含む実施例1〜6の各々の乾燥したタルクフリー組成物を得た。
