DESCRIPTION
form powder or granules autoignition temp. 698 °F concentration 48.0-49.5% extent of labeling 48% ethoxyl refractive index n20/D 1.47 (lit.) viscosity 100 cP, 5 % in toluene/ethanol 80:20(lit.) transition temp softening point 155 °C density 1.14 g/mL at 25 °C (lit.) DESCRIPTION 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. |
