Abstract

A composition that includes ethylhexyl sulfate or a salt thereof, an alkylbenzenesulfonic acid or a salt thereof, and a carrier. The ethylhexyl sulfate, or salt thereof, and the alkylbenzenesulfonic acid, or salt thereof, are present in a weight ratio of at least about 1:2. The composition can be used for killing or inhibiting a microorganism or pathogen (e.g., bacteria, gram-negative bacteria, gram-positive bacteria, enteric bacteria, virus, fungus, mold, mildew or powdery mildew).

Claims

1. A method of killing or inhibiting a microorganism or a pathogen, the method comprising contacting the microorganism or the pathogen with an effective amount of a composition comprising:

(a) ethylhexyl sulfate of the formula

2. The method of claim 1, wherein n has an average value of about 9 to about 11.

3. The method of claim 1, wherein the sodium hydroxide, potassium hydroxide, or combination thereof is present in ratio of less than about 1:

4, relative to the ethylhexyl sulfate, or salt thereof.

4. The method of claim 1, wherein the composition comprises:

(a) about 13 wt.% ethylhexyl sulfate, or salt thereof;

(b) about 11 wt.% dodecylbenzenesulfonic acid, or salt thereof;

(c) about 1.4 wt.% sodium hydroxide, and

(d) water.

5. The method of claim 1, wherein the contacting is in vitro.

6. The method of claim 1, wherein the contacting is in vivo.

7. The method of claim 1, wherein the contacting occurs on a surface of a plant or on a topical surface of a mammal.

8. The method of claim 1, wherein the microorganism or the pathogen is at least one of a bacteria, a virus, a fungus, a mold and a mildew.

9. The method of claim 1, wherein the microorganism or pathogen is at least one of a gram-negative bacteria, gram-positive bacteria and an enteric bacteria.

10. The method of claim 1, wherein the period of time effective to kill or inhibit the microorganism or the pathogen is less than about 30 seconds.

11. The method of claim 7, wherein the mammal is afflicted, or a risk thereof, with at least one of a bacterial disease, viral disease and a fungal disease.

12. The method of claim 7, wherein the plant is afflicted, or at risk thereof, with at least one of a bacterial disease and a fungal disease.

13. The method of claim 1, wherein n has an average value of about 8 to about 12.

14. The method of claim 1, wherein the composition is formulated as a fluid liquid.

15. The method of claim 1, wherein the composition is formulated for application by spraying the composition.

16. The method of claim 1, wherein the composition is formulated for application by spraying the composition.

17. The method of claim 1, wherein the composition optionally comprises a disinfectant selected from the group consisting of chlorine gas (Cl₂), ozone (O₃), lactic acid, ultraviolet light, peroxides, peracetic acid, potassium sorbate, lactic acid, and combinations thereof.

18. A method of washing a plant, the method comprising contacting the plant with an effective amount of a composition comprising:

(a) ethylhexyl sulfate of the formula

19. The method of claim 18, wherein n has an average value of about 9 to about 11.

20. The method of claim 18, wherein the sodium hydroxide, potassium hydroxide, or combination thereof is present in ratio of less than about 1:

4, relative to the ethylhexyl sulfate, or salt thereof.

21. The method of claim 18, wherein the composition comprises:

(a) about 13 wt.% ethylhexyl sulfate, or salt thereof;

(b) about 11 wt.% dodecylbenzenesulfonic acid, or salt thereof;

(c) about 1.4 wt.% sodium hydroxide, and

(d) water.

22. The method of claim 18, wherein an edible part of the plant is washed.

23. The method of claim 18, wherein the plant is washed before harvesting.

24. The method of claim 18, wherein the plant is washed after harvesting.

25. The method of claim 18, wherein the period of time effective to wash the plant is less than about 30 seconds.

26. The method of claim 18, wherein n has an average value of about 8 to about 12.

27. The method of claim 18, wherein the composition is formulated as a fluid liquid.

28. The method of claim 18, wherein the composition optionally comprises a disinfectant selected from the group consisting of chlorine gas (C1₂), ozone (O₃), lactic acid, ultraviolet light, peroxides, peracetic acid, potassium sorbate, lactic acid, and combinations thereof.
