A comparative study of various microencapsulation techniques: Effect of polymer viscosity on microcapsule characteristics

It is a comparative study of salbutamol sulpahte-ethylcellulose microcapsules prepared by three different microencapsulation techniques i.e. coacervation thermal change, solvent evaporation and coacervation non-solvent addition by adjusting the ratio of salbutamol sulpahte to ethylcellulose
