A head louse repellent under the brand name “Sumo” was launched in November 2005 by Phoenix Laboratories, Buenos Aires, Argentina. A license was given to Elea Laboratories for commercialization purposes of the product (in Latin America). The repellent is based on a patented formulation of a low concentration citronella. Its efficacy was tested in a double-blind clinical trial on the head of children.
