Abstract

An antimicrobial surface sanitizing composition comprising a major portion of diluent and an active antimicrobial agent, said agent comprising an antimicrobial effective amount of an alpha-hydroxy substituted mono- or di-carboxylic acid, and an antimicrobial effective amount of hydrogen peroxide, wherein after contact with the intended surface said antimicrobial composition leaves a noncontaminating residue upon that surface.

Claims

1. A antimicrobial sanitizer composition having a pH of 4 or less, said composition consisting essentially of:

a diluent and an antimicrobial agent, said agent consisting essentially of;

(a) about 0.9 wt-% to 2.5 wt-% of lactic acid; and

(b) about 0.25 wt-% to 3 wt-% hydrogen peroxide;

wherein after contact with a surface, said composition leaves a noncontaminating residue.

2. The composition of claim 1 wherein the compositional pH ranges from about 1.5 to about 3.75.

3. The composition of claim 1 wherein the compositional pH ranges from about 2 to 3.5.

4. The composition of claim 1 wherein said agent further consists essentially of a stabilizing agent present in a concentration ranging from about 0.05 wt-% to about 0.5 wt-%.

5. The composition of claim 1 additionally comprising a wetting agent, said wetting agent present in a concentration ranging from about 0.1 wt-% to about 1.5 wt-%.

6. The composition of claim 1 additionally comprising a skin conditioning agent, said skin conditioning agent present in a concentration ranging from about 0.5 wt-% to about 8 wt-%.

7. The composition of claim 1 additionally comprising a dye, said dye present in a concentration ranging from about 0.001 wt-% to about 0.01 wt-%.

8. The composition of claim 1 additionally comprising a thickener, said thickener present in a concentration ranging from about 0.1 wt-% to about 1.5 wt-%.

9. A method of using a antimicrobial sanitizing composition having a pH of 4 or less, said composition consisting essentially of a diluent, and an antimicrobial agent, said agent consisting essentially of:

(a) about 0.9 wt-% to 2.5 wt-% of lactic acid, and

(b) about 0.25 wt-% to 3 wt-% hydrogen peroxide;

wherein after contact with a surface said composition leaves a noncontaminating residue, said method comprising the steps of applying said composition to the surface of application for a sufficient period to result in a sanitization of the intended surface.

10. The method of claim 9 wherein said antimicrobial composition is used as a predressing carcass dip.

11. The method of claim 9 wherein said antimicrobial composition is used as a hard surface cleaner.

12. The method of claim 9 wherein said antimicrobial composition is used as a human hand wash.

13. A mammalian test dip sanitizing composition having a pH of 4 or less, said composition consisting essentially of a diluent and an antimicrobial agent, said antimicrobial agent consisting essentially of:

(a) about 0.9 wt-% to 2.5 wt-% lactic acid;

(b) about 2.5 wt-% to 3 wt-% hydrogen peroxide; and

(c) about 0.1 wt-% to 1 wt-% of a stabilizing agent;

wherein after contact with a surface said composition leaves a noncontaminating residue.

14. The composition of claim 13 wherein the compositional pH ranges from about 1.5 to about 3.75.

15. The composition of claim 13 wherein the compositional pH ranges from about 2 to 3.5.

16. The composition of claim 13 additionally comprising a wetting agent, said wetting agent present in a concentration ranging from about 0.25 wt-% to 1 wt-%.

17. The composition of claim 13 additionally comprising a skin conditioning agent, said skin conditioning agent present in a concentration ranging from about 3 wt-% to 6 wt-%.

18. The composition of claim 13 additionally comprising a dye, said dye present in a concentration ranging from about 0.002 wt-% to 0.004 wt-%.

19. The composition of claim 13 additionally comprising a thickener, said thickener present in a concentration ranging from about 0.01 wt-% to 1 wt-%.

20. A method of using a sanitizing mammalian teat dip composition having a pH of 4 or less, said composition consisting essentially of a diluent, and an antimicrobial agent, said agent comprising about 0.9 wt-% to 2.5 wt-% lactic acid, about 0.25 wt-% to 3 wt-% hydrogen peroxide, and about 0.1 wt-% to 1 wt-% of a stabilizing agent wherein upon application to the intended surface said composition leaves a noncontaminating residue, said method comprising the step of applying said composition to the surface of application for a sufficient time period to result in sanitization of the surface.
