Figure shows the chemical maps obtained for these samples at the initial time. As can be seen, there are no clusters of BTB at 5.0% (w/w). In the NLC structure the API tends to be solubilized in the liquid excipient, in this case, Dhaykol. This is seen in Figure , by the higher BTB concentration (in red) at places where there is higher concentration of Dhaykol, i.e., the two maps are correlated. On the other hand, the cetyl palmitate map is complementary to that of Dhaykol, indicating that these two compounds are not completely miscible. At 5% w/w BTB no agglomerates were observed, and it can be concluded that the two excipients have intermediary miscibility, with standard deviation in histograms around ± 10.3 units.
