Table 1.

Mean particle size (Zave, nm), polydispersity index (PDI), zeta potential (ZP), percentage of encapsulation efficiency (EE%), pH, and osmolarity (mOsm) of unloaded and FA-loaded NLC prepared using IPM (NLCa) or Lavandula EO (NLCb). Each value is the average of six different replicates ± standard deviation (SD). * Comparison between NLCa with IPM vs. NLCb with Lavandula, EO. ** Comparison of the loaded sample with the respective unloaded NLC, significance for p < 0.05.
