The influence of three non-ionic emulsifying agents, including Tween 20, Tween 40, and Tween 80, was investigated on the formation and some properties of nanoemulsions prepared from spearmint essential oil. The nanoemulsions were prepared using the ultrasonic emulsification method. The average particle size (Z-average), particle size dispersion index (PDI), zeta potential, viscosity, turbidity, pH, and physical stability of nanoemulsions were monitored at 4 degrees C for 35 days. The results showed that the nature and type of emulsifying agent had a significant effect (P < 0.05) on the properties mentioned above. As prepared samples with Tween 20 exhibited the lowest value (Z-average). It demonstrated that the emulsifiers Tween 20 and Tween 80 could be used to form nanoemulsions, in which the stability of nanoemulsion increased in the presence of Tween 20. The effect of storage time on the parameters of particle size (Z-average), particle size dispersion index (DPI), zeta potential, turbidity, and viscosity was statistically significant (P < 0.05).
