Patent ID: 8119688

Claim:
A method of reducing a viable microbial population comprising the steps of: a) combining an amount of water with an antimicrobials active agent to produce a differential evaporation potentiated antimicrobial composition said antimicrobials active agent miscible in said amount of water within a temperature range of about 5° C. and about 90° C., said antimicrobials active agent consisting essentially of a glycol ester selected from the group consisting of: an ethylene glycol monoester, an ethylene glycol diester, a propylene glycol monoester, propylene glycol diester, a butylene glycol monoester, and a butylene glycol diester, or combination thereof; b) applying said antimicrobial composition in a manner capable of contacting said viable antimicrobial population; and c) evaporating said amount of water from said antimicrobial composition within the temperature range of between about 5° C. and about 90° C. at a rate greater than said antimicrobials active agent evaporates from said antimicrobial composition, thereby increasing the percentage of said antimicrobials active agent during evaporation of said antimicrobial composition.
