FullMarks is a pediculicida without pesticides destroys lice and nits in just 10 minutes. It is odorless, colorless and can be used in children above two years old. The effectiveness and safety studies * that were conducted in collaboration with the Medical Entomology Center, Insect Research & Development Ltd. of Cambridge showed that the use of FullMarks in the treatment of lice infestation, during 10 minutes of application, were: 82% efficiency with FullMarks vs. 19.3% obtained with an equivalent based Permethrin. * The test was performed using a randomized clinical trial using two double-blind parallel group of people infested with lice. Composition: Formulation without pesticides. Isopropyl myristate, a fatty acid ether commonly used in cosmetics as a binding agent, emollient, solvent and skin conditioner. Cyclomethicone, a silicone fluid of low surface tension. Used in cosmetics as an emollient, humectant, controller the viscosity and capillary conditioning. Mode operation: The mixture of these ingredients block the tracheal respiratory system of the lice which rapidly become immobilized. In addition, the mixture coats the shell of the lice and dissolves the lipid layer to deteriorate and making it susceptible to water loss, so that the lice will dehydrate and die. Currently, there are no known mechanisms by which lice can develop resistance to this mode of action. FullMarks ingredients commonly used in cosmetics and its repeated use does not generate resistance and is well tolerated.
