Introduction

Cellulose series excipients are widely used in the pharmaceutical industry, and are primarily derived from natural cellulose through physical or chemical modification. Serving as diluents, binders, disintegrants, thickeners, and coating materials, cellulose series products provide basic and important solutions for drug formation, stability, controlled release and increased bioavailability.

Cellulose Series Range

Protheragen's cellulose range is comprehensive, spanning from microcrystalline cellulose to various cellulose derivatives. With our experienced technical knowledge and robust quality systems, we help our customers create safer, more effective, and stable pharmaceuticals.

• Microcrystalline and powdered cellulose

Microcrystalline cellulose and powdered cellulose are well known for their good compressibility and dilutibability, making them ideal for direct compression processes. They have different grades which are specifically designed for particle size distribution and bulk density. PH-102 is known for its excellent flowability, and PH-301 is balanced for hardness and disintegration.

• Cellulose ethers

The solubility or swelling properties of cellulose ethers endow them with good binder, thickener and film-forming properties. HPMC is the base material for film coating and gel-scaffold controlled release systems; EC is an insoluble polymer, which is used as a controlled-release coating material; CMC-Na is a good thickener and suspending agent for liquid preparations.

• Functional cellulose derivatives

These products are used to meet specific high-end needs. L-HPC and CMCC-Na are super disintegrants that can shorten the disintegration time of tablets; HPMCP and HPMCAS are classical enteric coating materials that can maintain integrity in gastric acid and dissolve in the intestinal environment.

• Specialized and composite cellulose

Products in this category are made to meet the needs of specific processes and dosage forms. Co-processed excipients such as SMCC and LMCC have multiple functions with synergistic effects that can greatly optimize the direct compression process.

Conclusion

The cellulose series of pharmaceutical excipients are essential components for ensuring drug quality, stability, and efficacy, comprehensively meeting the diverse needs of solid dosage forms, liquid formulations, and advanced drug delivery systems. From microcrystalline cellulose serving as a skeletal material to various cellulose derivatives that provide coating, thickening, and controlled-release functions, our products provide a solid foundation for addressing modern formulation challenges such as solubilizing poorly soluble drugs, improving process compliance, and achieving precise drug release.
