9. A substantially non-aqueous disinfectant composition, said composition comprising:
-
a glycol component present at about 5 weight percent to about 20 weight percent;
an alcohol component present at about 30 weight percent to about 70 weight percent; and
a conductivity control component present at about 15 weight percent to about 50 weight percent, said control component present in an amount sufficient to provide said composition a conductivity from about 0.01 microsiemens per centimeter to about 1.0 microsiemens per centimeter. - View Dependent Claims (10, 11, 12, 14, 15, 16, 17, 19, 20, 21)

13. A system for electrostatic delivery of an antimicrobial material, said system comprising:
-
a disinfectant composition comprising a glycol component, an alcohol component and a conductivity control component; and
an electrostatic dispensing apparatus containing said disinfectant composition in a liquid reservoir, said apparatus further including an electrostatic charging element, a voltage source electrically connected to said element, and a dispenser providing said disinfectant composition in proximity to said electrode, said proximity sufficient to electrostatically charge said composition.

18. A method of using a glycol to reduce airborne microbial levels, said method comprising:
-
providing an electrostatically dispensable glycol composition;
charging said glycol composition with an apparatus comprising an electrode conductively connected to a voltage source; and
dispensing said charged glycol composition in an amount and at a rate sufficient to effect a 3-log reduction in airborne microbial levels.

22. A substantially non-aqueous disinfectant composition, said composition comprising:
-
triethylene glycol present at about 10 weight percent to about 15 weight percent of said composition, said glycol having an initial viscosity and an initial conductivity;
ethanol present at about 45 weight percent to about 60 weight percent of said composition, said ethanol present in an amount sufficient to dissolve said glycol, said amount further sufficient to reduce said initial viscosity; and
a fragrance component present at about 20 weight percent to about 40 weight percent of said composition, said fragrance present in an amount sufficient to reduce said initial conductivity, said composition electrostatically dispensable, having a viscosity and a conductivity sufficiently reduced to deliver said composition at a rate of at least about 0.1 grams per hour to about 0.5 grams per hour. - View Dependent Claims (23, 24)
