Table 1.
Compositions of the selected ME formulations and their percent transmittance, particle size, and polydispersity Index (PdI).
| Microemulsion | Orange Oil (%) | Smix (%) | Water (%) | Transmittance ± SD (%) | Droplet Size ± SD (nm) | PdI ± SD |
|---|---|---|---|---|---|---|
| ME 20 | 20 | 70 | 10 | 98.52 ± 0.02 a | 73.42 ± 1.60 a | 0.216 ± 0.03 a |
| ME 25 | 25 | 65 | 10 | 97.51 ± 0.03 b | 75.17 ± 7.27 a | 0.224 ± 0.03 a |
| ME 30 | 30 | 60 | 10 | 96.18 ± 0.01 b | 77.63 ± 0.57 a | 0.223 ± 0.05 a |
For each test, means with the same letter are not significantly different. Thus, means with the different letter, e.g., “a” or “b” are statistically different (p < 0.05).
