There is disclosed a method for preventing or minimizing biodegradation of a substance which normally contains a naturally occurring optical isomer which comprises replacing the naturally occurring optical isomer with the corresponding unnatural optical isomer.
Claims20
A process for prolonging emanation of odor from a substance or surface containing one or more odoriferous optically isomeric compounds which process comprises selecting an unnatural optical isomer of the compound(s) for use in or on the substance or surface to prevent or delay biodegradation of the fragrance by microorganisms present on, or accidentally or deliberately contacting the substance or surface.
A process for rendering a substance or surface odoriferous for an extended period of time which comprises selecting an odoriferous compound which can exist in the form of optical stereoisomers, one being naturally occurring and the other being non-naturally occurring and applying to said substance or surface said non-naturally occurring optical stereoisomer to prevent or delay biodegradation of the odoriferous compound.
A process for rendering a substance or surface odoriferous for an extended period of time which comprises selecting an odoriferous compound which can exist in the form of optical stereoisomers, one being naturally occurring and the other being non-naturally occurring and applying to said substance or surface said non-naturally occurring optical stereoisomer to prevent or delay biodegradation of the odoriferous compound, wherein said odoriferous compound is a member selected from the group consisting of menthol, citronellal, linalool, menthone and menthyl acetate.
