In order to optimize the preparation conditions, a 23 factorial design was performed using different formulations of nanocapsules, which investigated the influence of three variables at two levels. The factors varied were the quantities of PCL, Span 60 and Myritol. The results were evaluated considering the size, polydispersity, zeta potential and association rate and the measures of these parameters were taken immediately after preparation and after 30 days of preparation. The formulations with minimum level of polymer in the preparation showed better stability results.pt-BRAtrazinePolymeric nanocapsulesModified release systemsDesenvolvimento de nanocápsulas de poli-e-caprolactona contendo o herbicida atrazina.Development of nanocapsules of poly-e-caprolactone containing herbicide atrazine.Artigo publicado em periodicoA Sociedade Brasileira de Química dá permissão à UFOP para reproduzir no RI/UFOP, uma cópia em formato eletrônico dos artigos completos, sem nenhuma edição e/ou modificação, publicados na revista Química Nova, que tenham como autores seus alunos e/ou professores.
