Summary of the physicochemical characteristics of a cationic oil-in-water nanoemulsion
| Parameter | Description |
|---|---|
| Aspect | White opaque to slightly translucent |
| pH | 5.0–7.0 |
| Osmolality (mOsmol/kg) | 270 |
| Droplet size (nm)a | < 200 |
| Zeta potential (ζ, mV)a | Positive (+40) |
| Sterility | Sterile |
Droplet size was determined by dynamic light scattering (HPPS, Malvern Instruments), and zeta potential by electrophoretic mobility measurement (Zetasizer 2000, Malvern Instruments).
