PROBLEM TO BE SOLVED: To provide a peracetic acid-based sterilizing detergent composition which has good sterilizing power and detergency, does not deteriorate a resin being a material for a vessel even when the composition is brought into contact with the resin for a long period of time, and is almost free from an irritating odor, in a peracetic acid-based sterilizing detergent composition in which a surfactant is blended.SOLUTION: The sterilizing detergent composition includes, to 1 pts.mass of peracetic acid: 1.5-4 pts.mass of hydrogen peroxide 10-20 pts.mass of acetic acid 0.1-2 pts.mass of a nonionic surfactant represented by general formula (1) below and water, wherein the concentration of the peracetic acid is 2.5 mass% or less on the basis of the total amount of the composition. R1-O-(-R2-O-)n-H...(1). In the formula (1), R1 represents a 8-18C hydrocarbon group, R2 represents an alkylene group having two or three carbon atoms, and n represents a number of 6-20.COPYRIGHT: (C)2013,JPO&INPIT【課題】本発明は、界面活性剤を配合した過酢酸系の殺菌洗浄剤において、良好な殺菌力と洗浄力と共に、容器の材質である樹脂に長期間接触しても当該樹脂を劣化させず、更に刺激臭の少ない過酢酸系の殺菌洗浄剤組成物を提供することにある。【解決手段】本発明は、過酢酸1質量部に対して、過酸化水素を1.5~4質量部、酢酸を10~20質量部、下記の一般式(1)で表されるノニオン界面活性剤を0.1~2質量部及び水を含有する組成物であって、組成物全量に対する過酢酸の濃度が2.5質量%以下であることを特徴とする殺菌洗浄剤組成物である:R1-O-(-R2-O-)n-H (1)(式中、R1は、炭素数8~18の炭化水素基を表し、R2は、炭素数2又は3のアルキレン基を表し、nは、6~20の数を表す)【選択図】図1
