Table 5. Physiochemical characterizations of nanoemulsions.

Nanoemulsions Droplet size (nm) pH value H/C Cent. Freeze-Thaw
Nano-1-Amp 5.26±0.04 A 7.76±0.03 A
Nano-2-Amp 94±1.48 B 8.31±0.05 B

H/C: Six heating-cooling cycles. Cent.: centrifugation at 3,000 rpm for 30min. Freeze-Thaw: Three freeze-thaw cycles. All data were analyzed by Duncan’s multiple range test using SAS software package. The different letters indicate a statistically significant difference (p ≤ 0.01).
