Formation of polymer particles with supercritical CO2: A review
Original language description
Recently some particle formation processes and micronization has been increased due to growing concerns regarding health, safety and the environment. The particle formation processes are either solvent-less or use environmentally acceptable solvents such as carbon dioxide have come into favor. Supercritical CO2 (sc CO2) (T > 31.1 oC, P > 7.3 MPa) has been used in pharmaceutical industries to minimize the use of organic solvents and micronize (0.1-5 mm) pharmaceuticals. Control of particle size increases the dissolution rate of drugs into the body. The low viscosity and high diffusivity of scCO2 offer the possibility of novel processing routes for drug delivery. There are several techniques for the particle formation which is used supercritical CO2 either as a solvent, and solution is rapidly expanded (rapid expansion of supercritical solutions, RESS), or as a solute leading to the formation of particles from gas-saturated solutions (PGSS), or as an anti-solvent leading precipitation induced particle formation as in (supercritical anti-solvent (SAS),gas anti-solvent (GAS) solution enhanced dispersion by supercritical fluid (SEDS) and aerosol solvent extraction systems (ASES)).
