General description
Ethyl cellulose(EC) is a hydrophobic andphysiologically inert cellulose derivative. It is widely used to preparephysiological dosage forms. It can also be used as a polymer coating,particle emulsion stabilizer and in pharmaceuticallyuseful aqueous latex dispersions.
Application
Ethyl cellulose can be used as a starting material to prepare zein-based nanofibers for controlled drug release. The addition of EC improves the solubility and mechanical properties of the composite nanofibers.
It can be used to prepare graphene-based ink for inkjet printing. This graphene oxide ink printed onto ITO surfaces can be used as an electrode for label-free DNA sensing.
Owing to its unique features such as gastroresistance, biocompatibility, and degradation to non-toxic and readily excreted products, EC is widely used in oral and topical drug dosage forms for the controlled release of the drug.
