설명

일반 설명

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.

애플리케이션

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.
