Ethyl Cellulose Pharmaceutical Used For Controlled release tablet coating
Ethyl Cellulose has a long history in film and bead coating for controlled release applications. It forms a strong film with good adhesion. Ethyl Cellulose can offer a versatile diffusion barrier whose properties can be modifed by film thickness (weight gain), level of water soluble pore-forming additives , plasticizer choice, solvent(s) used, or the viscosity (molecular weight) of Ethyl Cellulose.
