“…It has many advantages such as low organic solvent residual, better drug encapsulation, as well as controllable particle morphology and narrow particle size distribution [22][23][24]. The selective solvating power of supercritical fluids makes it possible to separate drugs and polymers from their organic solutions [25].…”

“…During this process a very fine dispersion of liquid phase occurs, so there is a very fine droplet and a high specific surface area for mass transfer. 5,20,23,24,28,29 ii. Freshly precipitated particles will remain in the system and the supercritical fluid and organic solvent drain from the system continuously.…”

“…During the SAS process, the Weber number is very high compared with that in other techniques. 12,28,40,56,63 The solubility of high-molecular-weight drugs in the supercritical fluid is related to the density. The solubility increases at higher densities and the effect of density on particle solubility is rapidly enhanced at higher densities.…”

“…Outra característica destas técnicas reside na eficiente separação do solvente e anti-solvente das partículas após a precipitação. É possível, então, evitar resíduos de solventes no produto e oferecer um reaproveitamento potencialmente vantajoso do solvente e do anti-solvente 20 .…”
