Abstract
A peroxygen antimicrobial composition is provided comprising an amine oxide and peroxygen compound. The combination of the two components produces an effective antimicrobial composition, providing a more potent biocide than can be obtained by using these compounds separately. Other components can be added to the composition such as peracetic acid, acetic acid, hydrotrope coupling agents, etc. The composition can be used to sanitize various surfaces such as hard surfaces found in food processing, food service and health care industries as well as to sanitize the surfaces of food and in the treatment of water.
Claims16
An antimicrobial composition comprising:
- hydrogen peroxide;
- and
- amine oxide of the formula (R1R2R3)NO, wherein R1 is an octyl group and R2 and R3 are alkyl groups having 1 to 2 carbon atoms;
- wherein the amine oxide and hydrogen peroxide are present at a weight ratio of 1:3 to 3:1;
- the composition having a minimum bactericidal concentration of less than 2000 ppm of hydrogen peroxide, amine oxide, or a combination thereof.
A method for reducing microbial population on contaminated surfaces comprising:
- selecting an antimicrobial composition comprising:
- hydrogen peroxide;
- and
- amine oxide of the formula (R1R2R3)NO, wherein R1 is an octyl group and R2 and R3 are alkyl groups having 1 to 2 carbon atoms;
- wherein the amine oxide and hydrogen peroxide are present at a weight ratio of 1:3 to 3:1;
- the composition having a minimum bactericidal concentration of less than 2000 ppm of hydrogen peroxide, amine oxide, or a combination thereof;
- and contacting the contaminated surface with the antimicrobial composition.
A method of reducing the microbial population of substantially fixed in-place process facilities comprising the steps of:
- introducing into the process facility a composition comprising:
- hydrogen peroxide;
- and
- amine oxide of the formula (R1R2R3)NO, wherein R1 is an octyl group and R2 and R3 are alkyl groups having 1 to 2 carbon atoms;
- wherein the amine oxide and hydrogen peroxide are present at a weight ratio of 1:3 to 3:1;
- the composition having a minimum bactericidal concentration of less than 2000 ppm of hydrogen peroxide, amine oxide, or a combination thereof;
- circulating the composition through the process facilities for a time sufficient to reduce the microbial population of the process facilities;
- and
- draining the composition from the process facility.
