Dissertação (Mestrado em Bioanálises e Medicamentos) - Universidade Federal do Rio Grande do Norte, Natal, 2008.https://repositorio.ufrn.br/jspui/handle/123456789/13437The inorganic actives, represented mainly by microfine zinc oxide and titanium dioxide, have shown great potential to protect against large UV spectrum. The aim of this study is the development, characterization and analysis of stability in the short term of microemulsions containing inorganic fotoprotection agents. The microemulsions identified by the phases diagram containing the metallic oxides were produced by two different methods and subjected to the centrifugation test and thermal stress cycles, and subsequently characterized by macroscopic evaluation, test dilution, electrical conductivity, pH, particle size, and zeta potential. This study highlights the influence of the metal oxides addition in the structure and distribution of micelles in the microemulsionsapplication/pdfAcesso EmbargadoMicroemulsãoDiagrama de fasesÓxido de zincoDióxido de titânioMicroemulsionPhases diagramZinc oxideTitan dioxidemasterThesisCNPQ::CIENCIAS DA SAUDE::FARMACIA
