Table 4.

Characterization of traditional and novel formulations (mean ± SD, n = 3). Similar experiments were performed for novel formulations. The results illustrate that in novel preparations, both S/C and percentage of surfactant and co-surfactant parameters affect mean particle size, although this relation is not completely significant (p = 0.135 and p = 0.085, respectively).
