However, in the present invention, the specific quaternary ammonium salt that is the component (A) is selected from the alkane sulfone salt, α-olefin sulfonate, and α-sulfomethyl ester salt that are the component (B). By selecting and using one or more anionic surfactants in combination, an unexpected effect of enhancing the bactericidal effect of the component (A) can be obtained.
