Description
従って、本発明の課題は、このような部分に於いても効果的な洗浄殺菌方法を提供することにある。
RO−(EO)n−H (1)
(式中、Rは炭素数8〜14の直鎖又は分岐鎖のアルキル基又はアルケニル基を示し、EOはエチレンオキシ基を示し、nは0〜5の整数を示す。)
で表される化合物〔成分(A)〕を硬質表面上の微生物に接触させ(工程1)、次いで、(B)塩素系酸化剤及びカチオン系殺菌剤からなる群から選ばれる少なくとも1種〔成分(B)〕を該微生物に接触させる(工程2)、硬質表面の洗浄殺菌方法を提供するものである。
(工程1)
工程1に用いる成分(A)は、一般式(1)
RO−(EO)n−H (1)
で表される化合物から成り、Rは炭素数8〜14の直鎖又は分岐鎖のアルキル基又はアルケニル基、EOはエチレンオキシ基、そしてnは0〜5の整数である。
また、これらの界面活性剤は成分(A)と目的に応じて任意の割合で併用することができるが、これら界面活性剤の含有量は、乳化・分散・可溶化性能を高める点から、0.001〜10重量%、さらに0.002〜7重量%、特に0.005〜5重量%が好ましい。
本工程は、工程1で成分(A)を硬質表面上の微生物に接触させた後、成分(B)として塩素系酸化剤及びカチオン系殺菌剤からなる群から選ばれる少なくとも1種を該微生物に接触させるにより行われる。一般にバイオフィルムが形成されると殺菌剤が効きにくい状況が起こるが、成分(A)よってバイオフィルム生成が抑制されると、殺菌剤の効力を十分に引き出すことが可能になる。
実施例及び比較例:
(実施例)
成分(A) RO−(EO)n−H
(A−1)C12アルコール〔カルコール2098、花王(株)製、R=C12アルキル、n=0〕
(A−2)C12アルコールエチレンオキサイド3モル付加物〔NIKKOL BL−3SY、日光ケミカルズ(株)製、R=C12アルキル、n=3〕
(比較例)
(A−3)C12アルコールエチレンオキサイド12モル付加物〔エマルゲン120、花王(株)製、R=C12アルキル、n=12〕
(菌液の作製、試験片の作製)
緑膿菌(Pseudomonas aeruginosa NBRC13275)をSoybean-Casein Digest Agar〔SCD寒天培地:日本製薬(株)製〕を用いて37℃、24時間前培養した。培地上に発育したコロニーを掻きとり、10mM滅菌リン酸バッファー(pH7.2)に懸濁した後、5,000×g、15分、10℃の条件で2回遠心洗浄し、再度10mM滅菌リン酸バッファー(pH7.2)に懸濁して、菌の濃度を600nm吸光度で1.0(OD600=1.0)に調整した菌液を作製した。その後、菌液100μLをスライドガラス(30×80×1mm)に塗布して試験片を作製した。
(工程1)
200mL滅菌スクリューカップ〔栄研器材(株)製)の中にミューラーヒントン培地〔日本ベクトン・ディッキンソン(株)製〕を100mL調製し、次いで表1に示す成分(A)の洗浄液を、ミューラーヒントン培地に対して所定濃度となるように添加して混合し、次いで、上記試験片を浸漬した。これらを37℃にて24時間保管した。
(工程2)
24時間後、試験片を抜き出し、予め200mL滅菌スクリューカップに調製しておいた表1の成分(B)の殺菌液100mLに投入、5分間浸漬させた。5分後、不活化液(※)20mLを添加し素早く攪拌して殺菌液の効力を停止させた。次いで、停止させた殺菌液0.1mLを標準寒天培地に塗抹し、37℃で24時間培養して、生育したコロニー数から試験片1枚当りの生菌数を算出し、以下の基準にて判定した。
◎:<103cfu/試験片1枚当り(検出下限未満)
○:103以上、104未満
△:104以上、105未満
×:105以上
※不活化液:LP希釈液30g(日本製薬(株)製)とチオ硫酸ナトリウム(無水)10gを精製水1Lに添加し、121℃・20分のオートクレーブ滅菌をしたもの
これらの結果を表1(実施例1〜7、比較例1〜4)に示す。
