Micronization, characterization and in-vitro dissolution of shellac from PGSS supercritical CO2 technique

The purpose of this investigation was to determine whether shellac, a naturally occurring material with enteric properties, could be processed in supercritical CO2 (sc-CO2) using the Particles from Gas Saturated Solution (PGSS) process and how process parameters affect the physico-chemical properties of shellac.
