Claims20
A particle comprising a water-insoluble polymer and a volatile material produced by a PGSS process.
A plurality of particles comprising a water-insoluble polymer and a volatile material produced by a PGSS process.
A process for making a particle, the process comprising the step of depressurizing a solution comprising a water-insoluble polymer and a volatile material and a highly compressible fluid dissolved in the solution such that a particle comprising the water-insoluble polymer and the volatile material is produced.
