Antimicrobial action
At the concentrations in this product, the efficacy achieved is > log5 (100,000 times) reduction in microbial counts against Gram positive and Gram negative bacteria, as well as fungi, and yeasts, enveloped and non-enveloped viruses, and spores.
Insecticidal action
F10® GERMICIDAL BARRIER OINTMENT WITH INSECTICIDE only. The insecticidal action is based upon cypermethrin (a pyrethroid). In the testing phases the indicator species used was Lucilia cuprina, a commonly occurring blow fly species. As soon as the larvae were sprayed they immediately began to migrate from the test site and within 30 minutes were dead. Other tests on L.cuprina eggs resulted in a 100% kill. The product was equally effective against adult flies and showed a 77% kill in 15 minutes rising to 100% within 30 minutes. Cypermethrin is a broad spectrum insecticide and is effective against other insects, eg biting flies, fleas, mosquitoes, and ticks.
