Regarding the Avon Skin So Soft Product, This may be of interest (from the consumer reseach site)....
"When tested under laboratory conditions against Aedes aegypti mosquitoes, this product's effective half-life was 30 minutes. Against Aedes albopictus, Skin-So-Soft oil provided 40 minutes of protection from bites, a duration 10 times less than that of 12.5% DEET. It has been proposed that the limited mosquito repellent effect of Skin-So-Soft oil could be caused by its fragrance or the presence of diisopropyl adipate and benzophenone in the formulation, both of which have some repellent activity"
Have no idea how accurate the info is mind you, but interesting none the same!
