The present invention provides substituted puleganic amides and compositions thereof, which are both useful as a topical treatment for skin, such as a repellant for insects and arthropods.
A process for the hydrogenation of a mixture of caryophyllenes by contact with hydrogen in the presence of a supported catalyst. The resulting products are useful for the application to skin.
Dihydronepetalactone, a minor natural constituent of the essential oil of catmints (
Nepeta
spp.) such as
Nepeta cataria
, has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.
The present invention relates to compositions of puleganic acid, and the use thereof as a topical treatment for skin, such as a repellant for insects or arthropods.

The present invention pertains to the field of clay compositions, and to tick- or insect-repellent compositions containing clay, particularly to tick- or insect-repellant formulations comprising dihydronepetalactone, a nepetalactam, a dihydronepetalactam and/or their respective derivatives and clay that provide sustained release to improve utilization of the active ingredient and require less-frequent renewal.
