Description

Ethyl Cellulose USP

Ethyl Cellulose USP is a high-purity, nonionic cellulose ether used in pharmaceutical formulations as a film-former, binder, and controlled-release polymer. Compliant with United States Pharmacopeia (USP) standards, it is widely utilized in oral solid dosage forms to modify drug release, improve coating performance, and enhance formulation stability.
Ethyl Cellulose is chemically derived from cellulose through ethyl ether substitution. It appears as a white to off-white, odorless granular powder or fine particles that are insoluble in water but soluble in many organic solvents. Its hydrophobic nature allows it to form strong, flexible films that are resistant to moisture.
In pharmaceutical applications, Ethyl Cellulose USP is used in:
• Controlled-release and sustained-release tablet and capsule coatings
• Film coatings to protect moisture-sensitive active ingredients
• Taste-masking coatings for bitter or unpleasant drugs
• Microencapsulation and multiparticulate systems
• Tablet binding and matrix formation
• Research involving modified-release drug delivery systems
Ethyl Cellulose USP functions by forming insoluble polymer films that control the diffusion of drug substances. By adjusting polymer viscosity and coating thickness, formulators can fine-tune release profiles ranging from immediate to extended release.
CarboMer supplies Ethyl Cellulose USP with details of viscosity grade, degree of substitution, purity, residual solvents, and microbial quality. The material meets USP monograph specifications and is suitable for regulated pharmaceutical manufacturing.
The material is packaged in sealed, moisture-resistant, tamper-evident containers. Available in laboratory, pilot, and commercial-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and full traceability.
Each batch is tested for identity (IR), viscosity, loss on drying, ethoxy content, ash content, and microbial limits. Technical support is available to assist with coating processes, solvent selection, and release profile optimization.
As with all CarboMer supplied cellulose-based excipients, Ethyl Cellulose USP is supported by dependable global supply, rigorous quality control, and expert technical guidance to ensure safe, effective, and consistent pharmaceutical product development.
