Particles size and zeta potential of eutectic emulsion droplets and ibuprofen particles.

Notes: *The particle size was significantly different from the eutectic emulsion (0 hour). **The particle size was significantly different from the eutectic emulsion at 48 hours after evaporation (suspension before ultrasonication). +The zeta potential was significantly different from the eutectic emulsion (0 hour). ++The zeta potential was significantly different from the eutectic emulsion at 48 hours after evaporation (suspension before ultrasonication). All the results were analyzed with P=0.05.

Abbreviation: PdI, polydispersity index.
