Abstract

This application relates to methods and compositions for cleaning and disinfecting unclean surfaces that are contaminated, typically with bacteria, viruses, yeast and molds. Broadly speaking contaminated surfaces includes hard and soft surfaces such as those found in household environments, in industrial environments, and hospitals, as well as surfaces of food products such as fruits, vegetables and meat. Further, the compositions can be prepared with naturally occurring components that are classified as generally considered as safe (GRAS) by the US FDA and/or comply with National Organic Production (NOP) standards of the USDA and can therefore be used in situations where such a classification is required such as organic food production.

Claims

1. A method of cleaning or disinfecting a surface comprising contacting said surface with a composition comprising

an organic surfactant comprising a blend of saturated and unsaturated fatty acid salts, selected from C₄-C₂₄ saturated and unsaturated fatty acid salts, such that the blend comprises at least about 1-6% C₆-C₁₀ fatty acids salts, and at least about 30% C₁₂-C₁₄ fatty acid salts;

and

an organic acid selected from the group consisting of citric acid, tartaric acid, lactic acid and malic acid;

or

an organic surfactant derived from the saponification of one or more natural oils and comprising at least about 1-6% caproic, caprylic and capric acid salts, and at least about 30% lauric and myristic acid salts; and

an organic acid selected from the group consisting of citric acid, tartaric acid, lactic acid and malic acid.

2. The method of claim 1 where the C₆-C₁₀ fatty acids salts are a blend of caproic, caprylic and capric acid salts.

3. The method of claim 1 where the C₁₂-C₁₄ fatty acid salts are a blend of lauric and myristic acid salts.

4. The method of claim 1 where the C₆-C₁₀ fatty acids salts are a blend of caproic, caprylic and capric acid salts and where the C₁₂-C₁₄ fatty acid salts are a blend of lauric and myristic acid salts.

5. The method of claim 1 where a biofilm is present on the surface.

6. The method of claim 1 where disinfecting the surface includes the control of gram positive bacteria, gram negative bacteria, viruses, yeast and molds.

7. The method of claim 1 where disinfecting the surface includes the control of gram positive bacteria, gram negative bacteria, viruses, yeast and molds, and where the gram positive bacteria, gram negative bacteria, viruses, yeast and molds exist in the presence of, or are incorporated into, biofilms.

8. The method of claim 1 further comprising the step of rinsing of the surface and removal of the excess solution.

9. The method of claim 1 where the organic acid is citric acid.

10. The method of claim 1 where the natural oils are selected from coconut oil and palm oil.

11. The method of claim 1 where the contacting of the surface by the composition is achieved by means of a low pressure applicator or a pressure washer.

12. The method of claim 1 where the contacting of the surface by the composition is achieved by means of Clean-In-Place technology.

13. The method of claim 1 where the surface is selected from a metallic, textile, plastic, glass, composite, plant material and protein surface.

14. The method of claim 1 where the surface is selected from a surface in the food and beverage industry.

15. The method of claim 1 wherein the components of the composition are generally regarded as safe (GRAS) by the US FDA for use on food or are acceptable under the regulations of the USDA National Organic Production (NOP).

16. A method of removing a biofilm from a surface comprising contacting said surface with a composition comprising

an organic surfactant comprising-a blend of saturated and unsaturated fatty acid salts, selected from C₄-C₂₄ saturated and unsaturated fatty acid salts, such that the blend comprises at least about 1-6% C₆-C₁₀ fatty acids salts, and at least about 30% C₁₂-C₁₄ fatty acid salts;

and

an organic acid selected from the group consisting of citric acid, tartaric acid, lactic acid and malic acid;

or

an organic surfactant derived from the saponification of one or more natural oils and comprising at least about 1-6% caproic, caprylic and capric acid salts, and at least about 30% lauric and myristic acid salts; and

an organic acid selected from the group consisting of citric acid, tartaric acid, lactic acid and malic acid.

17. The method of claim 16 where the C₆-C₁₀ fatty acids salts are a blend of caproic, caprylic and capric acid salts.

18. The method of claim 16 where the C₁₂-C₁₄ fatty acid salts are a blend of lauric and myristic acid salts.

19. The method of claim 16 where the C₆-C₁₀ fatty acids salts are a blend of caproic, caprylic and capric acid salts and where the C₁₂-C₁₄ fatty acid salts are a blend of lauric and myristic acid salts.

20. The method of claim 16 wherein the components of the composition are generally regarded as safe (GRAS) by the US FDA for use on food or are acceptable under the regulations of the USDA National Organic Production (NOP).
