Ethyl Cellulose Used in Pharmaceutical Applicaion
Due to its insolubility in water, ethyl cellulose is mainly used as tablet adhesive and thin film coating material, etc. I
t is also used as retarding agent for aggregate to make various types of aggregate slow-release pills; as slow-release agent or slow-release pills for compound material when making coat; as microcapsule material to make the medical effect release continuously, and avoid the preaction of water soluble medicine.
It can be too used in any type of medicine as dispersing agent, stabilizer and water retention agent to prevent medicine from absorption and deterioration, enhance the safe storage and stability of pills.
It can even be used as adhesive, slow-release agent and moisture-repellant agent for vitamine pills and mineral pills.
