【Characteristic】
| Characteristic | Description |
|---|---|
| Insolubility | Ethyl cellulose is insoluble in water but soluble in organic solvents such as ethanol, acetone, and toluene. |
| Film-forming ability | It can be dissolved in organic solvents to form clear, flexible films with excellent barrier properties against moisture and gases. |
| Controlled release | Ethyl cellulose is commonly used in controlled-release drug delivery systems, allowing for the regulated release of drugs over time. |
| Taste masking | It is utilized to coat drug particles, preventing the direct contact of drugs with taste receptors and masking their unpleasant taste. |
| Binding agent | Ethyl cellulose serves as a binder in various industries, providing cohesive strength and adhesion when combined with other materials. |
| Stability and compatibility | It is chemically stable and compatible with a wide range of materials, allowing for blending with other polymers or additives. |
【Application】
Due to its insolubility in water, ethyl cellulose is mainly used as tablet adhesive and thin film coating material, etc. It is also used as retarding agent for aggregate to make various types of aggregate slow-release pills; as slow-release agent or slow-release pills for compound material when making coat; as microcapsule material to make the medical effect release continuously, and avoid the preaction of water soluble medicine.
