Abstract
The present invention relates to two solvent antimicrobial compositions and methods employing these two solvent compositions. The two solvent compositions typically contain a second solvent that is not or is only sparingly soluble in a diluting solvent. The two solvent composition can form a clear single-phase solution. The two solvent antimicrobial compositions can reduce the population of microbes on various surfaces such as facilities, containers, or equipment found in food, beverage, or pharmaceutical industries at temperatures between about −70° C. to about 100° C.
Claims34
An antimicrobial concentrate and instructions for mixing the concentrate with water;
- the concentrate consisting essentially of antimicrobial solvent and antimicrobial agent;
- the antimicrobial solvent being benzyl alcohol, ethylene glycol phenyl ether, propylene glycol phenyl ether, propylene carbonate, phenoxyothanol, dimethyl malonate, dimethyl succinate, diethyl succinate, dibutyl succinate, dixnethyl glutarate, diethyl glutarate, dibutyl glutarate, dimethyl adipate, diethyl adipate, dibutyl adipate, dimethyl pimelate, diethyl pimelate, dimethyl suberate, diethyl suberate, dimethyl sebacate, diethyl sebacate, or mixture thereof;
- the antimicrobial agent being halogen containing antimicrobial agent, peroxycarboxylic acid, carboxylic acid, or mixture thereof;
- the amounts of antimicrobial solvent and antimicrobial agent in the concentrate being sufficient so that when the concentrate is mixed with water according to the instructions the resulting mixture will provide greater than a 1-log order reduction in population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C.
An antimicrobial composition consisting essentially of diluting solvent, antimicrobial solvent, and antimicrobial agent;
- the diluting solvent being water, glycol, CO2, or mixture thereof;
- the antimicrobial solvent being benzyl alcohol, ethylene glycol phenyl ether, propylene glycol phenyl ether, propylene carbonate, phenoxyethanol, dimethyl malonate, dimethyl succinate, diethyl succinate, dibutyl succinate, dimethyl glutarate, diethyl glutarate, dibutyl glutarate, dimethyl adipate, diethyl adipate, dibutyl adipate, dimethyl pimelate, diethyl pimelate, dimethyl suberate, diethyl suberate, dimethyl sebacate, diethyl sebacate, or mixture thereof;
- the antimicrobial agent being halogen containing antimicrobial agent, peroxycarboxylic acid, carboxylic acid, or mixture thereof;
- wherein the antimicrobial solvent and antimicrobial agent are at concentration effective to provide greater than a 1-log order reduction in the population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C.
An antimicrobial concentrate and instructions for mixing the concentrate with water;
- the concentrate consisting essentially of antimicrobial solvent, octanoic acid, hydrogen peroxide, and peroxyoctanoic acid;
- the antimicrobial solvent being benzyl alcohol, ethylene glycol phenyl ether, propylene glycol phenyl ether, propylene carbonate, phenoxyethanol, dimethyl malonate, dimethyl succinate, diethyl succinate, dibutyl succinate, dimethyl glutarate, diethyl glutarate, dibutyl glutarate, dimethyl adipate, diethyl adipate, dibutyl adipate, dimethyl pimelate, diethyl pimelate, dimethyl suberate, diethyl suberate, dimethyl sebacate, diethyl sebacate, octanoic acid, or mixture thereof;
- the amounts of antimicrobial solvent and peroxyoctanoic acid in the concentrate being sufficient so that when the concentrate is mixed with water according to the instructions the resulting mixture will provide greater than a 1-log order reduction in population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C.
An antimicrobial composition consisting essentially of diluting solvent, antimicrobial solvent, octanoic acid, hydrogen peroxide, and peroxyoctanoic acid;
- the diluting solvent being water, glycol CO2, organic acid, peroxide, inorganic acid, or mixture thereof;
- the antimicrobial solvent being benzyl alcohol, ethylene glycol phenyl ether, propylene glycol phenyl ether, propylene carbonate, phenoxyethanol, dimethyl malonate, dimethyl succinate, diethyl succinate, dibutyl succinate, dimethyl glutarate, diethyl glutarate, dibutyl glutarate, dimethyl adipate, diethyl adipate, dibutyl adipate, dimethyl pimelate, diethyl pimelate, dimethyl suberate, diethyl suberate, dimethyl sebacate, diethyl sebacate, octanoic acid, or mixture thereof;
- wherein the antimicrobial solvent and antimicrobial agent are at concentration effective to provide greater than a 1-log order reduction in the population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C.
