General description

Ethyl cellulose (EC) is a non-toxic, biocompatible, and hydrophobic polymer used for the sustained release preparation of pharmaceutical products.

Application

Ethyl cellulose can be used to prepare polymer coatings for various applications. For example, it is used to encapsulate salt hydrates for low-temperature heat storage applications.

It can be used as an efficient carrier for multiparticulate sustained drug delivery. For example, it can be used to develop polymeric microspheres for the controlled release of Ivabradine HCL (IBH).
