Method of treating target space, and liquid particles

摘要

According to the present invention, an arbitrary active constituent is sprayed stably so as to treat a target space. A method of the present invention, for treating a target space, includes the step of spraying, in the target space, a composition in an effective amount, the composition containing (i) a solvent and (ii) an electrolyte having a pK of not less than −10 but not more than 7, which pK is a dissociation constant with respect to water, the composition being sprayed as liquid particles in a mist form, which liquid particle have (I) an average particle diameter of not less than 100 nm but not more than 10 μm and (II) an average charge number of not less than +40 but not more than +40000.

1. A method of treating a target space, comprising the step of:
spraying, in the target space, a composition in an effective amount, the composition containing (i) a solvent, (ii) an electrolyte having a pK of not less than −10 but not more than 7, which pK is a dissociation constant with respect to water, and (iii) an active constituent, the composition being sprayed as liquid particles in a mist form, which liquid particles have (I) an average diameter of not less than 100 nm but not more than 10 μand (II) an average charge number of not less than +40 but not more than +40000, and the composition being sprayed as liquid particles so that, for at least 30 seconds in a time period from 1 minute after the spraying is finished to 120 minutes after the spraying is finished, an average of the number of the liquid particles in a space having a volume of 1 L is kept to be not less than 10 but not more than 1000.
