In a most preferred embodiment, the quaternary ammonium salt compound of the present invention is dodecyldimethylbenzyl ammonium bromide.

The inventor finds that by adding the biguanide compound and the quaternary ammonium salt compound into a formula system and utilizing the synergistic effect of the biguanide compound and the quaternary ammonium salt compound, the defect of common virus killing effect when the biguanide compound is used alone can be overcome, the disinfection capability of the quaternary ammonium salt compound can be improved, the disinfection and sterilization effects of the foam type household disinfectant can be effectively improved, and the application range of the disinfectant can be enlarged; in particular, the single-chain quaternary ammonium salt and the biguanide compound with the end containing the substituted phenyl are compounded, so that the effect is optimal; the possible reasons are that the guanidine group and the quaternary ammonium salt cooperate to further improve the electropositivity in the system, so that the bacterial virus is more easily adsorbed, the interaction between molecules is damaged, the lipid bilayer of the cell membrane is disrupted, the control of cytoplasm permeability is influenced, and cytoplasm leakage is caused, so that the bacteria and the virus cannot divide and reproduce and lose activity, other biomolecules existing in the bacterial cell are also decomposed, and the inactivation effect cannot be influenced even if the bacterial virus is mutated; however, the single-chain quaternary ammonium salt has the defect of easy precipitation at low temperature, and the application range of the disinfectant is seriously influenced.

The inventor unexpectedly finds that the precipitation of the single-chain quaternary ammonium salt at low temperature can be further slowed down by controlling the length of the carbon chain in the alkyl alcohol ether, and the possible reason is that the compound with the long carbon chain and the hydrophilic group is selected, wherein the long carbon chain can form a complex network structure with the quaternary ammonium salt to wrap the single-chain quaternary ammonium salt, so that the molecular mobility of the single-chain quaternary ammonium salt in a system is reduced, and the crystallization capacity is reduced; the surface activity of the non-polar group alkyl of the foaming agent can be increased by about 3 times when the non-polar group alkyl of the foaming agent is added with one carbon atom, so that the foaming capability can be increased, and the existence stability of the single-chain quaternary ammonium salt at low temperature can be improved; however, the non-polar group of the blowing agent is too long, and the solubility thereof is significantly reduced, resulting in a decrease in the blowing ability; long-term experimental research of the inventor shows that the alkyl alcohol ether has better effect when the carbon chain length is C10-C16.
