Embodiment

[0086] The fungicide compositions shown in Tables 1 to 4 were prepared, and the following evaluations were performed. The pH value is 7 at 20°C. The results are shown in Tables 1-4.

[0087] (1) 10 mL of LB medium was placed in a tissue culture flask, and bacteria (Staphylococcus aureus or Escherichia coli ) cultured in a petri dish were taken out through a platinum loop and placed in LB medium.

[0088] (2) The above-mentioned flask was incubated at 200 rpm and 37° C. for 16 hours.

[0089] (3) Transfer the above-mentioned LB medium to a 50 mL centrifuge tube, and perform centrifugation at 4000 rpm, 15° C., for 10 minutes.

[0090] (4) The LB medium in the supernatant was discarded, 10 mL of physiological saline was added, and centrifugation was performed again under the same conditions as in (3).

[0091] (5) The physiological saline in the supernatant was discarded, and physiological saline was added to prepare a bacterial solution with an OD (optical density) of 1.

Abstract

The present invention is a bactericide composition that contains: (a) an alkyl or alkenyl amine oxide that has a C7-18 alkyl group or alkenyl group; and (b) a mono- or polyoxyalkylene alkyl or alkenylamine that has a C8-24 alkyl group or alkenyl group and has an average number of added moles of oxyethylene groups of 1-8.

Description

technical field [0001] The invention relates to a bactericide composition, a bactericidal method, and a method for enhancing the bactericidal effect of the bactericide composition. Background technique [0002] In recent years, the use of antiseptic compositions in household or personal care compositions has flourished due to increased hygiene awareness. [0003] As such a fungicide composition, Japanese Patent Laid-Open No. 11-246310 discloses a fungicide effective in sterilizing bacteria belonging to the genus Legionella, which contains a specific amine oxide as an active ingredient. In addition, Japanese Patent Application Laid-Open No. 2017-88903 discloses a cleaning and disinfecting liquid composition containing a specific amine oxide-type surfactant having a linear alkyl group and a specific metal in a specific ratio. Salt. [0004] On the other hand, Japanese Patent Application Laid-Open No. 2016-84422 discloses a liquid detergent composition containing a specific a...
