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. The inventive insect repellent, formulated in a volatile silicone fluid, was shown to repel and incapacitate stable flies. This finding demonstrated that repellency was not limited to mosquitoes, but extends to other biting flies or insects, thus demonstrating the utility of the novel insect repellent for protecting pets and livestock as well as humans.

The Federal EPA has consistently limited the use of known toxicants (insecticides) to preclude their admixture into paints and coatings by contractors or homeowners for the purpose of repelling or killing insects on the dried or cured coating. The current invention utilizes materials taken from the EPA's GRAS (Generally Recognized as Safe) List for this purpose. Furthermore, the current invention utilizes the insect repellant nature of these materials to repel insects from the area during coating application, thereby eliminating the need for topical insect repellants such as DEET.

The Federal EPA has consistently limited the use of known toxicants (insecticides) to preclude their admixture into paints and coatings by contractors or homeowners for the purpose of repelling or killing insects on the dried or cured coating. The current invention is a method to repel, rather than kill, insects, arachnids, and other arthropods, utilizing materials taken from the EPA's GRAS (Generally Recognized as Safe) List, obviating onerous Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) regulations and greatly extending the useful life of the insect-repellant materials by binding them into the dried film solids—greatly slowing their evaporation and degradation and creating a timed release of insect repellant material. Furthermore, the current invention utilizes the insect repellant nature of these materials to repel insects from the surrounding area during coating application, thereby eliminating the need for applying insect repellants, such as DEET, to the skin.

The invention relates to a water-based fluid preparation with moisturizing, skin protecting and mosquito expelling functions, belonging to the chemical field.
