EC N-grade – Cellulose Ether – CAS 9004-57-3

CAS number 9004-57-3, Ethylcellulose (EC)  is a type of cellulose ether. Ethylcellulose is produced through the reaction of cellulose with ethyl chloride in the presence of a catalyst. It is a white, odorless, and tasteless powder that is insoluble in water but soluble in many organic solvents.

Ethylcellulose is widely used in various industries for its film-forming, thickening, and binding properties. Here are some key features and applications of Ethylcellulose:

1. Film Formation: Ethylcellulose forms clear and flexible films when dissolved in organic solvents. This property makes it suitable for applications in coatings, adhesives, and controlled-release pharmaceutical formulations.
2. Thickening Agent: While Ethylcellulose itself is insoluble in water, it can be used as a thickening agent in oil-based formulations, such as in paints, varnishes, and inks.
3. Binder: Ethylcellulose acts as a binder in various industries, including pharmaceuticals, where it helps to bind the ingredients of tablets and pellets together.
4. Controlled Release: In pharmaceuticals, Ethylcellulose is often used in controlled-release formulations, where it provides a barrier that regulates the release of active ingredients over time.
5. Inkjet Printing: Ethylcellulose is used as a binder in ink formulations for inkjet printing, providing viscosity and improving print quality.

Ethylcellulose is valued for its versatility, biocompatibility, and stability. It is generally regarded as safe for use in pharmaceuticals, food, and cosmetic applications.
