Description
(A)殺菌成分として、クエン酸、酢酸、乳酸、リン酸、リンゴ酸、コハク酸、アジピン酸、フマル酸(以上、和光純薬工業社製)、(B)芳香族スルホン酸塩(殺菌効力増強成分)として、m−キシレンスルホン酸ナトリウム(東京化成工業社製)、p−トルエンスルホン酸ナトリウム(和光純薬工業社製)、メシチレンスルホン酸ナトリウム(東京化成工業社製)、クメンスルホン酸ナトリウム(Ark Pharm,Inc社製)を表1、表2に示す配合割合(質量%)で配合し、精製水を加えて100重量%として試験液(本発明1〜21)を得た。
本発明、比較例の試験液990μLに、黄色ブドウ球菌(S.aureus)の培養液10μLを接種してよく攪拌した後、混合液をSCDLP培地で100倍希釈した。接種から希釈までの時間は10分間とした。この希釈液を滅菌済みのプラスチックシャーレに固化させておいたSCDLP寒天培地上に100μL滴下し、コンラージ棒でよく延ばした後、37℃で培養を行い、発生するコロニー数を計測した。また、対照例(ネガティブコントロール)として試験液の代わりに滅菌水を用いたものも用意した。試験液で処理したものと対照例のコロニー数の比較により除菌率を算出した。
殺菌成分としてクエン酸を1質量%、殺菌効力増強成分としてm−キシレンスルホン酸ナトリウムを5質量%、ノニオン界面活性剤としてポリオキシエチレンラウリルエーテルを2質量%加えたものに、最終的にバランスとして水を加えて100質量%に調製し、よく混合して浴室用殺菌洗浄剤を作製した。
