(a) Nanoemulsion mean droplet size obtained by the PIC method for different w/w oil mixtures, (b) nanoemulsion mean droplet size obtained by the PIT method for different w/w oil mixtures and (c) change of relative transmittance values for all the prepared nanoemulsions vs. time for different oil mixtures. All samples were prepared with a 10% w/w of surfactant at the final composition. The relationship of cinnamon oil/olive oil was kept constant at 30/70. Measurement and storage temperature was 25 °C.
