Abstract

The present disclosure relates to compositions including a fatty acid soap/fatty acid mixture, and methods of use thereof. The compositions include a C5 to C12 fatty acid or mixtures thereof. The compositions show increased activity, e.g., insecticidal, soil removal, antimicrobial activity, at a controlled pH range of about 7.5 to about 9.0.

First claim

1 .- 30 . (canceled)

31 . A method of using a cleansing, sanitizing insecticidal composition comprising:
providing an effective amount of a composition comprising
(a) a fatty acid;
(b) a neutralizer;
(c) a buffer; and
(d) a carrier;
wherein the composition has a pH of about 7.5 to about 9.0;
contacting the composition with an insect and/or a surface; and wetting the insect and/or the surface surrounding the insect; wherein the composition has insecticidal, cleansing, and sanitizing efficacy.

32 . The method of claim 31 , wherein the fatty acid comprises a branched or straight chain C5 to C12 fatty acid.

33 . The method of claim 32 , wherein the fatty acid is selected from the group consisting of hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, decanoic acid, lauric acid and mixtures thereof.

34 . The method of claim 31 , wherein the neutralizer comprises an alkali metal hydroxide.

35 . The method of claim 34 , wherein the alkali metal hydroxide is selected from the group consisting of sodium hydroxide, potassium hydroxide, and mixtures thereof.

36 . The method of claim 31 , wherein the neutralizer is selected from an amine, an alkanolamine, and mixtures thereof.

37 . The method of claim 31 , wherein the buffer is selected from a weak acid, a weak base, an ampholyte buffering agent, and mixtures thereof.

38 . The method of claim 31 , wherein the buffer is selected from citrate, citric acid, a bicarbonate, and mixtures thereof.

39 . The method of claim 31 , wherein the carrier comprises water.

40 . The method of claim 31 , wherein the composition comprises:
(a) about 1.0 wt. % to about 10 wt. % of the fatty acid; (b) about 1.0 wt. % to about 10 wt. % of the neutralizer; (c) about 0.1 wt. % to about 1.0 wt. % of the buffer; and (d) at least about 80 wt % of the carrier.

41 . The method of claim 31 , wherein the composition wets the insect within 60 seconds of contact.

42 . The method of claim 41 , wherein the composition completely wets the insect immediately upon contact.

43 . The method of claim 31 , wherein the composition provides at least a 2.5 log kill rate against a microbial population.

44 . The method of claim 43 , wherein the microbial population is a viral, bacterial, fungal, algal, sporal, lichenous, protozoan, virion, viroid, and/or phagous population.

45 . The method of claim 31 , wherein the composition provides a kill rate of at least about 60% of insects.

46 . The method of claim 31 , further comprising a thickening agent selected from xanthan gum, guar gum, polyethylene oxide, polyvinyl pyrrolidone, polyvinyl alcohol, clay thickener, betonite, carboxyl methyl ether cellulose, kaolin, soy protein and mixtures thereof.

47 . The method of claim 31 , further comprising an additional ingredient selected from an insecticide, an essential oil, 2-phenyl ethyl propionate, a residual insecticide, and mixtures thereof.

48 . The method of claim 31 , wherein the pH is about 8.0 to about 8.5.

49 . The method of claim 31 , wherein the fatty acid comprises decanoic acid, and the neutralizing agent comprises potassium hydroxide.

50 . The method of claim 31 , wherein the composition is a surface active mixture which results in improved packing and surface activity.
