Abstract
In this study, polymeric nanocapsules of PCL containing the herbicide atrazine were prepared. 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.
