Abstract

The present invention relates to compositions including surfactant peroxycarboxylic acid, methods for making these compositions, and methods for reducing the population of a microorganism.

Claims (27)

1. A composition comprising:

an effective antimicrobial amount of surfactant peroxycarboxylic acid, the peroxycarboxylic acid selected from the group consisting of-an alcohol ethoxyperoxycarboxylic acid of the formula:

wherein R is C 12 H 25 , C 13 H 27 , or a mixture thereof; and n is 3;

a sulfo peroxysuccinic acid comprising laurethsulfoperoxysuccinic acid; and

an alkylamine peroxycarboxylic acid of the formula

wherein R1 is C 8 H 17 and the nitrogen can be protonated or unprotonated; and R 2 can be H or OH, and mixtures thereof; and

about 0.0005 to about 40 wt-% carboxylic acid surfactant, the carboxylic acid surfactant selected from the group consisting of alcohol ethoxycarboxylate, sulfo succinate, alkylamine carboxylate, and mixtures thereof.

2. The composition of claim 1 , comprising:

about 0.0005 to about 15 wt-% of the surfactant peroxycarboxylic acid; and

about 0.0005 to about 25 wt-% of the carboxylic acid surfactant.

3. The composition of claim 1 , further comprising about 0.0005 to about 50 wt-% oxidizing agent.

4. The composition of claim 1 , further comprising about 0.001 to about 80 wt-% acidulant.

5. The composition of claim 1 , further comprising about 0.00002 to about 10 wt-% stabilizing agent.

6. The composition of claim 1 , further comprising about 5 to about 99.9999 wt-% carrier.

7. The composition of claim 1 , wherein the alcohol ethoxyperoxycarboxylic acid comprises linear alcohol ethoxy peroxycarboxylic acid.

8. The composition of claim 1 , wherein the alcohol ethoxycarboxylate comprises linear alcohol ethoxycarboxylate.

9. The composition of claim 1 , wherein the sulfosuccinate comprises laurethsulfosuccinate.

10. The composition of claim 1 , wherein the alkylamine carboxylate comprises alkyliminodipropionate.

11. A method of reducing population of microorganism on an object, the method comprising:

contacting the object with a surfactant peroxycarboxylic acid composition;

the composition comprising:

an effective antimicrobial amount of surfactant peroxycarboxylic acid, the peroxycarboxylic acid selected from the group consisting of an alcohol ethoxyperoxycarboxylic acid of the formula:

wherein R is C 12 H 25 , C 13 H 27 , or a mixture thereof: and n is 3;

a sulfo peroxysuccinic acid comprising laurethsulfoperoxysuccinic acid; and

an alkylamine peroxycarboxylic acid of the formula

wherein R1 is C 8 H 17 and the nitrogen can be protonated or unprotonated; and R 2 can be H or OH, and mixtures thereof; and

about 0.0005 to about 40 wt-% carboxylic acid surfactant, the carboxylic acid surfactant selected from the group consisting of alcohol ethoxycarboxylate, sulfo succinate, alkylamine carboxylate, and mixtures thereof.
