Abstract

Changes in the environment, such as population growth, the process of globalization and climate change are some of the contributions to the emergence of epidemics. The main arboviruses that affect the country are Dengue, Yellow Fever, Chikungunya and Zika, which have the mosquito Aedes aegypti as the main vector. Such diseases present several symptoms such as fever, headache, rash, malaise, edema and joint pain. The use of repellents, have been one of the methods used to protect against the mosquito. Being that these products act by forming a layer on the skin with repulsive odor to the insect. However, some commonly used repellents have been shown to be toxic, especially for pregnant women and newborns. It should be noted that these groups are classified as at risk for vaccination (in the case of yellow fever), which increases the risks and the possibility of infection. In this context, the present project aims to develop a repellent based on slow release systems, from zein nanoparticles containing the active Icaridin and Geraniol incorporated into a cellulose gel matrix. These systems would allow a reduction of the amount of active, reduction of the toxicity besides the fact that the use of mixture of assets could allow the reduction of processes of resistance by the insects. In addition, stability and release assays of the hydrogel actives to be formulated will be performed. Thus, the present proposal emerged from the motivation to develop long-lasting repellents that can protect the population and also ensure health and well-being, especially to pregnant women and newborns due to the search for systems that have low toxicity and high efficacy.
