Ability to plasticise sufficiently in supercritical CO2, 2. Ability to form an inter-polymer complex in supercritical CO2, 3. Ability to swell in aqueous medium in order to release actives, and 4. FDA-approved.enSupercritical fluidsPolymer complexesSupercritical CO2Plasticisation mediumAqueous mediumFDAReportLabuschagne, P. W.
