Ethyl cellulose is a non-ionic ethyl ether of cellulose containing not less than 44 % and not more than 51% of ethoxy groups, calculated on dried basis. They are soluble in a wide range of organic solvents. When water-soluble binders cannot be used, ethyl cellulose is often the polymer of choice. They are classified into a range of polymer viscosities for different applications.

Micro encapsulation - Stabilize against active interactions, hydrolysis and oxidation

Tablet coating - Impart sustained release to film coatings

Tablet binder - Plastic flow, suitable for direct compression, injection molding and melt extrusion

Flavor Masking - Improved taste through suppression of strong flavors
