Brief content The aim of this work is to determine whether the presence of nanodispersion of gas influences the physicochemical properties of solutions of ehtanol and glycerine, including surface tension, viscosity and contact angles on glass. Results indicated small, but noticeable decrease of the viscosity of both ethanol and glycerine solutions in presence of nanodispersion. There was significant increase in the ethanol solutions’ surface tension for ethanol volume fractions in range 0.1 to 0.3. Similar effect was not observed for the glycerine solutions. The contact angles for both ethanol and glycerine solutions were similar for solutions with and without nanobubbles presence.
