本発明のミスト又は蒸気として用いる殺菌用の過酸化水素水溶液(本明細書において、「本発明の過酸化水素水溶液」ということもある)は、過酸化水素と、オルトリン酸又はホスホン酸と、アルミニウムと、硫酸イオンとを含む。更に、本発明の過酸化水素水溶液は、噴霧ノズルや蒸発器などに付着した蒸発残渣の水洗性を容易にするための添加剤として、その他の酸及び/又は塩を含んでもよい。
本発明の殺菌方法は、本発明の過酸化水素水溶液をミスト又は蒸気として対象物に接触させることを特徴とする対象物の殺菌方法に関する。本発明の過酸化水素水溶液の詳細については、上述のとおりである。
過酸化水素の安定性及び蒸発残分は、JIS-K1463に規定された方法で評価した。
過酸化水素水溶液中のリン酸と硫酸イオン濃度は、イオンクロマトグラフィーDX-500(Dionex製)で測定した。
過酸化水素水溶液中のアルミニウム濃度は、ICP発光分析装置iCAP 6000(Thermo Fisher SCIENTIFIC製)で測定した。
模擬蒸発器は公知の蒸発器を参考に縮小模擬したものを用いた。過酸化水素濃度35%の過酸化水素水溶液サンプルは、300℃に加熱した模擬蒸発器に、空気と混合させながら一定速度で送液して気化させ、80時間試験した。過酸化水素濃度25%の場合は112時間とした。試験後の模擬蒸発器重量を測定し、試験前との重量差を付着量(mg)とした。さらにこれをイオン交換水で水洗、乾燥して再度重量を測定し、試験前との重量差を残留量(mg)とした。付着量と残留量から、下記式に基づいて水洗除去率(%)を算出した。
水洗除去率(%)=[1-{残留量(mg)/付着量(mg)}]×100
(模擬蒸発器構造)
材質: SUS304L
サイズ:150mm×23mmφ円筒気形気化室の先端に高さ17mmの円錐形ノズルをつけたもの。円錐形ノズルは先端に2mmφの穴が開いたものを用いる。
(条件)
過酸化水素水溶液サンプルの送液流量:1.25mL/min
空気流量: 2.1L/min
イオン交換水流量: 500ml/1.5min
ノズル口のガス流体温度:100~120℃
過酸化水素水サンプル300mlにSUS304L製のテストピース(30mm×30mm×2mm)2枚を入れ、45℃にて24時間静置した。
蒸留精製し、純水で35%に濃度調整した過酸化水素水に、オルトリン酸(後藤化学株式会社製、リン酸(濃度85.0%))3質量ppm、硫酸カリウムアルミニウム(和光純薬工業株式会社製、硫酸カリウムアルミニウム12水和物(濃度96.5%))1質量ppm、硫酸ナトリウム(和光純薬工業株式会社製、硫酸ナトリウム10水和物(濃度99.0%))0.5質量ppmを添加した。このときの硫酸イオン/Al比は14であった。この過酸化水素水溶液サンプルの蒸発残分は6質量ppmであり、蒸発器付着量は12.3mg、付着物の水洗除去率は59%であった。
過酸化水素濃度、硫酸カリウムアルミニウム添加量、硫酸ナトリウム添加量をそれぞれ変えて実施例1と同様の実験をおこなった。それぞれの含有量は表1に記載のとおりである。これらの過酸化水素水溶液サンプルの硫酸イオン/Al比は、10~20の範囲である。蒸発器付着物の水洗除去率は60%前後であった。
過酸化水素濃度、硫酸カリウムアルミニウム添加量、硫酸ナトリウム添加量をそれぞれ変えて実施例1と同様の実験をおこなった。それぞれの含有量は表1に記載のとおりである。これらの過酸化水素水溶液サンプルの硫酸イオン/Al比は、10~20の範囲を外れている。これらの過酸化水素水溶液サンプルの蒸発器付着量は一部のサンプルで悪化が見られ、また水洗除去率はすべてにおいて大きく低下する結果となった。また、安定剤がリン酸のみでは、付着量の増加とSUS浸漬後の安定度低下が顕著であった。
比較例6についても、過酸化水素濃度、硫酸カリウムアルミニウム添加量、硫酸ナトリウム添加量をそれぞれ変えて実施例1と同様の実験をおこなった。それぞれの含有量は表1に記載のとおりである。比較例6の過酸化水素水溶液サンプルの硫酸イオン/Al比は、10~20の範囲内であるが、オルトリン酸の含有量が8ppmを超えている。このサンプルでは蒸発器付着量および水洗除去率のいずれも悪化した。
