液体防腐剤組成物の製造
表1に示すパラヒドロキシ安息香酸エステル(A)を、同表に示す予め混合しておいた水混和性有機溶剤(B)に添加し、約60℃に加温しながら溶解させて液体防腐剤組成物を製造した。
上記の通り製造された各液体防腐剤組成物5mLを50mL容のバイアル瓶に入れ、密栓した後、4℃の冷蔵庫内に保管し、7日間経過後の外観を観察した。
上記安定性試験において、パラヒドロキシ安息香酸メチルを含有し、析出が生じず安定していた実施例1、3および4ならびに比較例3、6および17の各組成物について、日本化学療法学会標準法(微量液体希釈法)に準じ、最小発育阻止濃度(MIC)の測定を行った。
供試菌1:Escherichia coli NIHJ-JC2(大腸菌)
供試菌2:Staphylococcus aureus IFO13276(黄色ブドウ球菌)
供試菌3:Pseudomonas aeruginosa ATCC13736(緑膿菌)
供試菌4:Candida albicans FDA2138(酵母様真菌)
供試菌5:Aspergillus niger ATCC16404(黒麹カビ)
上記安定性試験において、パラヒドロキシ安息香酸ブチルを含有し、析出が生じず安定していた実施例2および5〜7、ならびに比較例8、10および19の各組成物について、抗菌力試験1と同様の方法、同様の供試菌にてMICを測定した。結果を表4に示す。
上記安定性試験において、パラヒドロキシ安息香酸メチルを含有し、析出が生じず安定していた実施例1、3および4、ならびに比較例3、6および17の各組成物を用いて飽和水溶液100mLを調製し(パラヒドロキシ安息香酸エステルが析出した時点で飽和に達したものと判断した)、水溶液中のパラヒドロキシ安息香酸エステルの総量を比較した。また、パラヒドロキシ安息香酸ブチルを含有し、析出が生じず安定していた実施例2および5〜7、比較例8、10および19の各組成物についても同様に比較した。
