EC Ethyl Cellulose Pharmaceutical Used For Controlled Release Tablets
Product Description:
Ethyl cellulose is a type of cellulose derivative that is widely used in various industries. It is derived from cellulose, which is a natural polymer found in the cell walls of plants. Ethyl cellulose is produced by chemically modifying cellulose with ethyl groups, which results in a non-ionic, water-insoluble polymer.

Pharmaceutical use of Ethyl Cellulose's :
Application | Description |
---|---|
Controlled-release drug delivery systems | Ethyl cellulose is used as a matrix material in the formulation of controlled-release oral dosage forms, providing prolonged drug release. |
Taste masking | It is employed to coat drug particles, masking the unpleasant taste and odor of drugs, improving patient compliance, particularly in pediatrics and geriatrics. |
Enteric coatings | Ethyl cellulose is used to formulate enteric coatings that protect drugs from the acidic environment of the stomach, enabling drug release in the intestine. |
Sustained-release implants | Ethyl cellulose is utilized in implants, enabling the sustained release of drugs over an extended period of time. |
Granulation and binding agent | It serves as a granulating agent, enhancing flow properties and compressibility of powders during tablet manufacturing. Additionally, it acts as a binding agent, holding powdered ingredients together in tablets. |
Stabilizer in liquid formulations | Ethyl cellulose functions as a stabilizer in liquid dosage forms, such as suspensions and emulsions, preventing settling and separation of components. |
