一般描述
Ethyl cellulose is a lipophilic polymer that possesses excellent membrane-forming ability and durability. It facilitates the formation of free films and is utilized in studying the dynamic interaction of polymer films with water.
应用
Ethyl cellulose has been used in the preparation of biostructures such as matrices, microspheres, microparticles, pellets and tablets for use in drug delivery. It has also been used in making chemically modified ethyl cellulose-based membrane for the purification of IgG.

Loratadine-loaded microspheres were prepared by spray-drying of dispersions, emulsions and suspensions differing in polymeric composition and solvents used. Conventional microspheres were obtained by spray-drying of dispersions composed of chitosan (CM) as only polymer, while composed microspheres were obtained by spray-drying
