RESUMO

This study aimed to evaluate and select different dermatological bases incorporated with propolis for veterinary use as well as to analyze the chemical compounds of the propolis hydroalcoholic extract by LC-MS/MS. Thus, formulations were submitted to accelerated stability tests under different temperatures and to mechanical stress, and evaluated for the appearance, color, odor, pH, viscosity, spreadability, and the mean size of the dispersed globules from the internal phase during a period of three months. The creamy gel formulation showed satisfactory results for all the evaluated items with an excellent capability to incorporate the hydroalcoholic extract of propolis associated to the maintenance of its physicochemical properties. The propolis used in this study had been shown to possess antibacterial and antifungal in vitro activity against the main microorganisms responsible for such diseases. Therefore, the propolis creamy gel described here could be a promising formulation for use in the veterinary medicine.
