Description
2BN+3H2O → B2O3+2NH3
<梱包体の作製>
市販の六方晶窒化ホウ素粉末(デンカ株式会社製、グレード:C-7N)20gを、図1に示すような形態に梱包した。外装体(外袋)としては、厚さ7μmのアルミニウム蒸着膜を有するチャックタイプの袋(エーディーワイ株式会社製、商品名:MBY-6565ZIPS)を用いた。この外装体の厚さは89μmであり、外側から、PET/SPE/Al/SPE/PEが積層された層構造を有していた。また、水蒸気透過度は、0.1g/(m2・24h)以下であった。この水蒸気透過度は、JIS K 7129-5:2016に準拠して、温度20℃、90RH%の試験条件において測定された値である。
25℃、25%RHに設定した恒温恒湿器(A)と、40℃、75%RHに設定した恒温恒湿器(B)を準備した。上述の梱包体を複数作製し、恒温恒湿器(A)及び(B)内のそれぞれにおいて保管した。1ヶ月経過毎に、恒温恒湿器(A)及び(B)から梱包体を一つずつ取り出し、外袋及び内袋を開放して六方晶窒化ホウ素粉末を採取し、溶出ホウ素を測定した。
製造直後及び保管後の各六方晶窒化ホウ素粉末の溶出ホウ素を、医薬部外品原料規格2006に基づく方法で抽出し、ICP発光分光分析装置で測定した。具体的には、六方晶窒化ホウ素粉末2.5gをフッ素系樹脂製ビーカーに採取し、エタノール10mLを加えてよくかき混ぜ、さらに水40mLを加えてよくかき混ぜた。その後、ビーカーの上端部にフッ素系樹脂製時計皿をのせ、50℃で1時間加温した。冷却後、該ビーカーの内容物をろ過して得られたろ液と、少量の水による残留物の洗液とを合わせて回収液とした。
外装体(外袋)として、市販のポリエチレン製の袋を用いたこと、及び、吸湿材を用いなかったこと以外は、実施例1と同様にして六方晶窒化ホウ素粉末の梱包体を作製した。そして、実施例1と同様にして梱包体を保管するとともに、溶出ホウ素の測定を行った。恒温恒湿器(A)で保管した場合の結果は図2、及び恒温恒湿器(B)で保管した場合の結果は図3に示すとおりであった。
