Because Ethyl Cellulose is insoluble in water but is soluble in many organic solvents, it is used as an adhesive agent in tablets and granules. It can increase the hardness and reduce the friability of a tablet.
Additionally, common applications are as a film-forming agent to improve the appearance of a tablet, isolating taste and avoiding disintegration of water-sensitive drugs. By preventing water absorption, tablets can be stored for a longer period of time. It can also be used to reinforce sustained-release tablets.
