The present invention relates to a disinfectant containing a certain kind of water-soluble polymer (polycation) as an active ingredient. More specifically, it relates to a disinfectant whose active ingredient is a polycation containing a quaternary ammonium salt structure and a hydroquinone structure in its main chain. Low-molecular-weight quaternary ammonium salt compounds are known to have bactericidal effects, and are currently used for bactericidal and
Although it is used as a disinfectant, there is a desire to develop a disinfectant with even higher antibacterial effects. The mechanism of action of quaternary ammonium salt compounds on bacteria is that they adsorb to the bacterial cell surface through electrostatic and hydrophobic interactions, followed by diffusion into the cell, resulting in destruction of the cell membrane and The process of killing off is considered. Therefore, to obtain higher fungicidal activity, it is necessary to change the chemical structure of the fungicide to obtain optimal charge density, intercharge distance, and hydrophobicity.
However, with low-molecular-weight quaternary ammonium salt compounds, such free molecular design is difficult, so there is a natural limit to the improvement of bactericidal activity. As a result of repeated research to improve the drawbacks of these conventional antibacterial agents using low-molecular-weight quaternary ammonium salt compounds, the present inventors found that the general formula () (R in the formula is a polymethylene group or xylylene group, Y is chlorine, bromine or
