Ethylcellulose, also written as Ethyl Cellulose, is a cellulose ether and non-ionic polymer widely used as a pharmaceutical excipient in tablet coating, modified-release formulations, granulation and drug-delivery systems. It is produced by introducing ethoxy groups into the cellulose polymer structure.
Ethylcellulose is valued for its film-forming, binding, water-barrier and controlled-release properties. Its water-insoluble nature makes it particularly useful for developing formulations where drug release needs to be controlled through a polymeric barrier.
Swapnroop Pharma supplies Ethylcellulose in India for pharmaceutical formulation and manufacturing applications, with grades selected according to viscosity, ethoxy content and intended formulation requirements.
Pharmaceutical-grade Ethylcellulose is available in different grades with controlled ethoxy substitution and viscosity characteristics. These properties influence polymer solubility, film strength, coating performance and drug-release behavior.
Ethylcellulose is commonly used as a film former, coating agent, binder, matrix former and modified-release excipient.
Ethylcellulose is a derivative of cellulose in which some hydroxyl groups are converted to ethyl ether groups. Its CAS Number is 9004-57-3.
Because Ethylcellulose is a polymer, it does not have one fixed molecular weight like a low-molecular-weight chemical. Commercial grades are primarily differentiated by characteristics such as ethoxy content and viscosity.
Ethylcellulose is practically insoluble in water and can be processed using suitable organic solvents depending on the formulation and grade.
Ethylcellulose is used in pharmaceutical formulations for:
Ethylcellulose is particularly valuable in modified-release pharmaceutical formulations because its water-insoluble polymeric film can act as a barrier to drug diffusion.
The final release profile depends on polymer grade, viscosity, polymer concentration, coating thickness, plasticizer, drug properties and overall dosage-form design.
Ethylcellulose can form durable films around pharmaceutical dosage forms. It can contribute to protection against moisture and can also be incorporated into coating systems designed to provide modified drug release.
The polymer can be used with appropriate plasticizers, solvents and other excipients according to the formulation-development requirements.
