<Sterilization test>
The following bacteria were used.
Moraxella osloenesis 49 strain: isolated from clothing

Strains stored at −30 ° C. in 10% glycerol aqueous solution were thawed, spread on SCDLP agar medium, and cultured at 37 ° C. overnight. The cultured bacteria are suspended in sterilized ion-exchanged water and centrifuged (2800 r / min × 15 minutes). D = 1.2 (approximately 10 ⁹ cfu / ml). A solution (100 g) was prepared by diluting 0.1 g of the fungicide composition described in Table 2 or 0.1 g of the cleaning composition for clothing described in Table 3 with ion-exchanged water. Bacteria were added to a solution obtained by diluting the disinfectant composition or the detergent composition for clothing so that the amount of the bacteria would be 10 ⁷ cfu / ml, and contacted at 25 ° C. and 150 rpm for 15 minutes to prepare a test solution. 0.5 ml of the test solution is dropped into 4.5 ml of LP diluent (Nippon Pharmaceutical Co., Ltd.) to inactivate the bactericidal components, and then the extract is serially diluted, and the SCD-LP agar medium (Nippon Pharmaceutical Co., Ltd.) And then cultivated at 37 ° C. for 1 day. The number of colonies obtained was counted, and the common logarithm of the number of viable bacteria treated with sterilized ion-exchanged water was subtracted from the common logarithm of the number of viable bacteria of each Example or Comparative Example (logarithmic value) Was defined as a bactericidal activity value (1). The bactericidal activity value was similarly determined using the control bactericidal composition or the control clothing cleaning composition corresponding to each example or comparative example, and this was defined as bactericidal activity value (2). The bactericidal composition having a bactericidal activity value (1) / bactericidal activity value (2) of 0.7 or more, which is the ratio of the bactericidal activity value (1) to the bactericidal activity value (2), was accepted. When the bactericidal activity value (1) / bactericidal activity value (2) is 0.7 or more and 1 or less, the bactericidal effect is maintained, and when it exceeds 1, it can be said that the bactericidal effect is enhanced. The bactericidal activity value (1) / bactericidal activity value (2) is the bactericidal activity ratio.
