得られた配合液のPAAとH2O2濃度及びpHを表2に示す。また、比較例1〜3のそれぞれのPAAに対する実施例1〜3のPAAの増加率を合わせて表2に示す。更に、酢酸配合量に対するPAA濃度の変化を図1に示す。図1中、×はKMPSを使用しない例(比較例1〜3)を、□はKMPSを1.94重量%含む例(実施例1、2−1、3)を、■はKMPSを3.88重量%含む例(実施例2−2)を意味する。
実施例1〜3で使用したものに加え、下記有機酸
プロピオン酸(関東化学社製鹿特級グレード)
コハク酸(関東化学社製鹿特級グレード)
グルタル酸(関東化学社製試薬)
クエン酸(扶桑化学工業社製無水品)
を使用した。表3に示す割合で原料を混合して配合液を得た。得られた配合液の100℃にて3時間加熱処理後のPAAとH2O2濃度及びpHを表3に示す。また、実施例4〜21において、KMPSを添加しないこと以外は同一の比較例4〜21に対するPAA増加率を表3に示す。
過酸化水素を18重量%、酢酸9重量%、HEDPを0.48重量%、過硫酸塩又は硫酸水素塩をX重量%とし、DIWにより全量を100重量%となるように配合液を調製した。使用した過硫酸塩又は硫酸水素塩を下記する。

1)実験方法
(a)供試検体
実施例6、実施例4、実施例18の組成物および比較用として比較例4、比較例6、比較例18、比較例26(いずれも100℃にて3時間加熱品)の組成物
i)試験菌
Escherichia coli IFO3972(大腸菌)
Staphylococcus aureus IFO13276(黄色ブドウ球菌)
ii)試験菌液の調製
試験菌をSCD寒天培地で35℃、24時間培養する。更にその1白金耳を新しいSCD寒天培地に移植し、35℃、24時間培養する。この前培養菌を滅菌生理食塩水に懸濁し、約108個/mlに調製したものを試験菌液とした。
