Resumo

OF MICROPARTICLES SYSTEMS.Cellulose acetate produced from mango seed fibers cellulose was used as a matrix for preparation of microparticles empty and load with acetaminophen (Paracetamol) in order to evaluate the incorporation of an active agent during the formation of microparticles.The microparticles are characterized by Fourier Transformed Infrared spectroscopy (FTIR), Differential Scanning Calorimetry (DSC) and Scanning Electron Microscopy (SEM).The incorporation of paracetamol can be confirmed by the change in value of glass transition temperature (Tg).The formation of microparticles spherical was observed by SEM and showed an average diameter of 1.010 and 0.950 μm for empty and load microparticles respectively.
