MALODOUR COUNTERACTING TREATMENT

摘要

A method of counteracting or neutralising airborne malodour comprising directing at the source of the malodour liquid droplets from a spray device containing a malodour counteracting composition, the method comprising imparting a unipolar charge to the said liquid droplets by double layer charging during the spraying of the liquid droplets by the spray device, the unipolar charge being at a level such that the said droplets have a charge to mass ratio of at least +/- 1 x 10<-4> C/kg.
