According to its developers, Faso soap is made of shea butter, lemongrass, African marigold and other "natural ingredients" that can be found in Burkina Faso.[3] The soap's purpose is to leave an insect-repelling odor on the user's skin after washing.[4]
In April 2016, a crowd funding campaign was initiated[5] in order to finance large-scale testing of the product and an amount of over 70,000 Euros was reportedly collected.[6]
Other soaps
A similar mosquito-repellent soap is in development at Johns Hopkins. The program, headed by Dr. Soumyadipta Acharya, uses permethrin in its soap. Permethrin is a shorter-lived compound that can "comfortably reside on [the] skin."[4]
