Ethyl Cellulose is a cellulose derivative produced by substituting ethoxy groups for hydroxyl groups in cellulose. It is a non-ionic, water-insoluble polymer widely used as a pharmaceutical excipient in solid and modified-release dosage forms.
Ethyl Cellulose is valued for its film-forming, binding, coating and moisture-barrier properties. Its controlled permeability makes it particularly useful in pharmaceutical formulations requiring modified drug release.
Swapnroop Pharma supplies Ethyl Cellulose in India for pharmaceutical formulation, coating, granulation and other industrial applications, with grade, viscosity and substitution characteristics selected according to the intended use.
Pharmaceutical-grade Ethyl Cellulose is available in different viscosity grades and ethoxy-content ranges. The selection of grade can influence film formation, solution viscosity, coating performance and drug-release characteristics.
It is commonly used in pharmaceutical formulations as a film former, binder, coating agent, matrix former and modified-release excipient.
Ethyl Cellulose is derived from cellulose through ethylation of its hydroxyl groups. It is represented by the general polymeric formula:
[C₆H₇O₂(OC₂H₅)₃]ₙ
Its CAS Number is 9004-57-3. Because Ethyl Cellulose is a polymer, it does not have one fixed molecular weight in the same manner as a small organic molecule. Commercial pharmaceutical grades are generally differentiated by ethoxy content and viscosity grade.
Ethyl Cellulose is practically insoluble in water but can dissolve in selected organic solvents, making it useful for solvent-based coating and formulation processes.
Ethyl Cellulose is used as a pharmaceutical excipient in:
One of the major applications of Ethyl Cellulose is modified drug release. Because the polymer is water-insoluble, it can form a barrier around or within a dosage form, allowing drug release to be controlled through diffusion and formulation design.
The final release profile depends on factors such as polymer grade, viscosity, polymer concentration, coating thickness, plasticizer system, drug properties and dosage-form design.
Ethyl Cellulose can be used as a film-forming polymer in pharmaceutical coating systems. It can provide a protective and moisture-resistant coating while also supporting modified-release functionality.
It may be incorporated into coating formulations together with suitable plasticizers, solvents and other formulation components according to the product-development requirements.
