Ethyl Cellulose For Pharmaceutical Grade
CAS NO 9004-57-3
Appearance: white or off-white powder
Viscosity: 4-350cps in 2% solution
Ethyl Cellulose are recognized and used globally for many different functional purposes in pharmaceutical products.They are frequently used in controlled-release, solid-dosage formulations as well as for protective coatings for water-sensitive or reactive ingredients. They are also useful as granulation binders, as film formers, to improve tablet integrity and appearance,and to mask the taste of bitter active ingredients
What is Ethyl Cellulose functions for different Pharmaceutical Grade?
- Granulation: Ethyl Cellulose is often used for solvent granulation of water-sensitive materials
- Coating: Ethyl Cellulose could be used as solvent-based tablet and bead coatings, they could form strong films with good adhesion.
- Tablet Binding: Ethyl Cellulose powder is used as tablet binders in dry granulation or direct compression formulations.
- Microencapsules: Ethylcellulose works as encapsulation excipients to prepare sustained-release microcapsules to enable sustained release of drug efficacy and prevent some water-soluble drugs from taking effect prematurely
What other application Ethyl Cellulose Could be used for ?
- Paint, coating,printing inks
- Varnishes/Lacquers
- Pharmaceutical
- Food/Feed
