Destabilization of SLN formulations. (A) Changes in particle size (measured by DLS) and nanoparticle concentration (assessed by NTA) in SLN composed of 10% cetyl palmitate and decreasing concentrations (5 to 0.1%) of poloxamer 188; (B) correlation between particle size and concentration (r = −0.81). (C,E) TEM images of SLN1, prepared with 5% PL, and its corresponding particle size distribution profile (F), calculated with ImageJ software; (D) TEM image of SLN5, prepared with 0.1% PL, for which it was not possible to obtain the distribution size profile (see text). Magnification and scale bars are displayed per sample.
