Abstract

Antimicrobial compositions and methods of using such antimicrobial compositions to provide a reduction in populations of viable microorganisms.

Claims

1. A method of reducing a population of microorganisms capable of reproduction, comprising:

obtaining a differential evaporation potentiated antimicrobial composition including an antimicrobially active agent and water, said antimicrobially active agent miscible in said water, said antimicrobially active agent having an initial concentration of between about 5 percent to about 10 percent by volume, said antimicrobially active agent consisting essentially of ethylene glycol monobutyl ether; and

contacting said population of microorganisms capable of reproduction with said differential evaporation potentiated antimicrobial composition, said differential evaporation potentiated antimicrobial composition having a concentration of said antimicrobially active agent which increases during a period of time in which said water evaporates from said composition resulting in a concentration of said antimicrobially active agent which provides greater than a 2-log₁₀ order reduction in said population of microorganisms capable of reproduction.

2. The method of claim 1, further comprising reducing said population of microorganisms capable of reproduction by greater than said 2-log₁₀ order within a period of time after contacting said population of microorganisms capable of reproduction with said differential evaporation potentiated antimicrobial composition of not greater than thirty minutes.

3. The method of claim 2, further comprising contacting said population of microorganisms capable of reproduction while contained in an amount of diluent miscible in said antimicrobial composition.

4. The method of claim 3, wherein said population of microorganisms capable of reproduction is selected from the group consisting of:

Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Aspergillus niger, and Clostridium sporogenes.

5. The method of claim 1, further comprising:

evaporating said water from said differential evaporation potentiated antimicrobial composition to generate an azeotrope of said antimicrobially active agent combined with said water.

6. The method of claim 5, wherein combining said antimicrobially active agent with said water occurs within a temperature range of about 5°

C. and about 90°

C. at 760 mm Hg.

7. The method of claim 6, wherein evaporating occurs within said temperature range of between about 5°

C. and about 90°

C. at 760 mm Hg.

8. The method of claim 7, wherein evaporating leaves no residue.
