Fig. 4From: In vitro characterization of self-emulsifying drug delivery system-based lipsticks loaded with ketoconazoleIllustration of influence of the amount of beeswax and carnauba wax interaction: a Contour plot, b 3D surface plot for softening point and c Contour plot, and d 3D surface plot for percent drug release after 12 h. A comparison of the predicted and actual experimental data of the lipstick formulation is given in (e) softening point, and (f) percent drug release after 12 hBack to article page
