General description

Ethyl cellulose is a non-toxic, physiologicallyinert, and stable hydrophobic polymer. It is widely used in the preparation ofsustained release matrices for drug delivery systems.

Application

Ethyl cellulose can be used:
  • To prepare polymeric microcapsules of Alachlor and Metolachlor to study their controlled-release properties.
  • As a core matrix to synthesize biphasic drug release nanofibers.
  • To prepare wax-based solid dispersion pellets with excellent floating and sustained-release ability.
