Abstract: This disclosure provides insect or arthropod pesticidal compositions of mono alpha carboxylic acids or esters thereof in combination with an emulsifier, an adjuvant comprising choline, and a carrier. Also provided are aqueous concentrates comprising the pesticidal compositions, as well as aqueous dilutions of the aqueous concentrates. Also provided are methods of killing or incapacitating insects or arthropods and methods of treating cattle to protect against biting insects or arthropods using such compositions.

Abstract: The present invention provides an insect or arthropod pesticidal composition. The composition includes active ingredients having a mixture of fatty acids, each of the fatty acids having a straight carbon chain from 6 to 12 carbon atoms long. The fatty acid mixture includes a first fatty acid molecule having a straight carbon chain from 6 to 8 carbon atoms long, and a carboxylic acid group. The fatty acid mixture also includes a second fatty acid molecule having a straight carbon chain from 8 to 12 carbon atoms long, and a carboxylic acid group. The composition also includes a carrier that promotes adherence or absorption or transport across the surface of insects or arthropods to effect their incapacitation or death.

Abstract: A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on the human skin surface. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The new natural repellent exhibits the longevity and repellency that is comparable to N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, but the inventive natural repellent is more acceptable than DEET, which has an unpleasant odor and imparts a greasy feel to the skin.
