Ethylcellulose N10 (EC N10)
CAS Number: 9004-57-3
Ethylcellulose N10 is a water-insoluble cellulose ether with a 5% toluene/ethanol viscosity of approximately 10 mPa·s, used as a film coating material for sustained-release applications and as a binder in sustained-release matrix tablets. It forms robust, moisture-resistant films that are impermeable to water, enabling precise control of drug diffusion.
