The aims of this study were to development and evaluated the physical stability of O/W emulsions containing "Pequi" oil (Caryocar brasiliense). O/W emulsions containing 10.0% (w/w) of Pequi oil were prepared, and to improve the stability, the carbomer, magnesium sulfate, sodium chloride and sorbitan oleate were added and studied. The direction of the emulsions was evaluated by dilution method and by macroscopic analysis, the appearance, homogeneity and organoleptic properties were evaluated. The centrifugation, freeze/defrost cycles and stress thermal were used to investigate the preliminary stability. To evaluate the accelerated stability, the samples were stored at different stress conditions and evaluated the pH value, macroscopic analysis and rheological behaviour. The O/W emulsions prepared with Pequi oil, 0.3% (w/w) of Acrylates/C10-30 Alkyl Acrilate Crosspolymer and 0.2% (w/w) of Carbomer have been found to be stables. These presented pseudoplastic flow behaviour and thixotropy. The macroscopic characteristics, the pH values and the values of the apparent viscosity, both consistency and flow index and hysteresis areas during aging indicated good long-term stability of this formulation.Downloads
