Abstract
Abstract Described are isomeric mixtures of bisabolene prepared by dehydrating nerolidol using citric acid or phosphoric acid and then distilling the resulting product at particular temperature ranges and particular pressure ranges in order to prepare a composition of matter useful for augmenting or enhancing natural, dry, floral, opoponax aromas with floral, freesia, fruity, citrus, bergamot, mango and opoponax topnotes in perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener composiitions, drier-added fabrics softener articles, cosmetic powders and the like; and useful for repelling specific species of insects, namely, house flies Musca domestica L. (Diptera Muscidae)) and the species of mosquitoes, Aedes aegypti.

Claim 1
Independent Claim
116 words
A method of repelling at least one of the insect species: (a) Musca Domestica L.(Diptera:Muscidae); and/or (b) Aedes aegypti from a three dimensional space inhabited by at least one of said insect species comprising the step of exposing said three dimensional space inhabited by at least one of said insect species to a: (a) Musca domestica L.(Diptera:Muscidae); and/or (b) Aedes aegypti repelling concentration and quantity of an insect repellent composition of matter consisting essentially of bisabolene isomers defined according to the structure: ##STR59## wherein in the mixture in each of the compound one of the dashed lines represents a carbon-carbon double bond and each of the other of the dashed lines represents a carbon-carbon single bond.
Claim 2
Independent Claim
116 words
A method of repelling at least one of the insect species: (a) Musca Domestica L.(Diptera:Muscidae); and/or (b) Aedes aegypti from a three dimensional space inhabited by at least one of said insect species comprising the step of exposing said three dimensional space inhabited by at least one of said insect species to a: (a) Musca domestica L.(Diptera:Muscidae); and/or (b) Aedes aegypti repelling concentration and quantity of an insect repellent composition of matter consisting essentially of bisabolene isomers defined according to the structure: ##STR59## wherein in the mixture in each of the compound one of the dashed lines represents a carbon-carbon double bond and each of the other of the dashed lines represents a carbon-carbon single bond.
Claim 3
Independent Claim
217 words
A method of repelling at least one of the insect species: (a) Musca domestica L.(Diptera:Muscidae); and/or (b) Aedes aegypti from a three dimensional space inhabited by at least one of said insect species comprising the step of exposing said three dimensional space inhabited by at least one of said insect species to a: (a) Musca domestica L.(Diptera:Muscidae); and/or (b) Aedes aegypti repelling concentration and quantity of an inspect repellent composition of matter consisting essentially of a bisabolene isomer containing composition prepared by treating nerolidol defined according to the structure: ##STR60## with a catalyst selected from the group consisting of phosphoric acid and citric acid and heating the composition in the presence of a solvent at a temperature of from 155° up to 175° C. for a period of time such that a majority of isomers is prepared defined according to the structure: ##STR61## and, in addition, a minority of a mixture is prepared comprising compounds having the structures: ##STR62## wherein the mixture of compounds defined according to the structure: ##STR63## one of the dashed lines represents a carbon-carbon double bond and each of the other of the dashed lines represents carbon-carbon single bonds and fractionally distilling the resulting product at a temperature in the range of 109°-124° C. and a pressure in the range of 2.8-3.20 mm/Hg.
