Ethyl cellulose (EC, CAS 9004-57-3) is a non‑ionic cellulose ether with excellent film-forming, thickening, adhesion, and organic solubility. It is widely used in pharmaceuticals, food, coatings, cosmetics, and industrial materials.
1. Pharmaceutical Applications
Controlled-release coatings: Used as a membrane-forming material for sustained‑ and delayed‑release tablets, pellets, and capsules.
Matrix materials: Serves as a skeleton component to regulate drug release rate.
Binder & granulating agent: Improves the hardness and molding of tablets and granules.
Microencapsulation & taste masking: Forms protective films to cover unpleasant odors or isolate sensitive ingredients.
Transdermal patches & topical formulations: Used in gels, ointments, and film‑forming topical products.
2. Food Industry
Edible coating agent: Provides moisture‑proof, oil‑proof, and gloss-improving films for candies, nuts, and fruits.
Stabilizer & thickener: Enhances texture and prevents phase separation in confectionery, beverages, and baked goods.
Emulsion stabilizer: Improves the stability of fat‑containing food systems.
3. Coatings, Inks & Adhesives
Wood & paper coatings: Improves adhesion, water resistance, and flow properties.
Printing inks: Acts as a binder and rheology modifier for gravure and screen inks.
Adhesives: Used in special adhesives requiring flexibility and film strength.
4. Cosmetics & Personal Care
Film-former: Used in hair care, sunscreens, and skin care products to form uniform films.
Thickener & stabilizer: Enhances product texture and emulsion stability.
5. Industrial & Specialty Uses
Electronic materials: Binder for conductive pastes and circuit inks.
Insulating materials: Used in cable insulation and protective coatings.
Ceramic & powder metallurgy: Binder for green body forming.
Special polymer modifiers: Improves toughness and processability of composites.
