Hydroxypropyl Cellulose Analysis Service | Pharmaceutical Excipient

Hydroxypropyl cellulose (HPC) is a nonionic cellulose ether obtained by partial substitution of cellulose molecules with hydroxypropyl groups. Its unique physicochemical properties, including water solubility, thermal reversibility, good film-forming ability, and surface activity, make it widely used in the pharmaceutical industry. HPC can serve not only as a binder and disintegrant for tablets but also as a film-coating material and controlled-release carrier, enhancing formulation stability, regulating drug release rate, and improving patient compliance.

With increasingly stringent pharmacopeial standards and the continuous development of novel dosage forms, parameters such as the degree of substitution, molecular weight, viscosity, impurity levels, and application suitability of HPC have become critical quality attributes for pharmaceutical companies. Leveraging advanced analytical platforms and a professional team, MtoZ Biolabs offers a hydroxypropyl cellulose analysis service for research institutions and pharmaceutical companies to ensure the stability and reliability of excipients in compliance with both research and production requirements.

 

Services at MtoZ Biolabs

The quality evaluation of HPC typically involves multiple dimensions: structural identification, hydroxypropoxy substitution level, physicochemical properties, impurity control, and functional performance. MtoZ Biolabs has established a complete testing system based on international pharmacopeial requirements and advanced analytical methods. Using infrared spectroscopy, gas chromatography, nuclear magnetic resonance, thermal analysis, rheology, and elemental analysis, we can systematically assess the key quality attributes of HPC.

 

In response to clients’ research needs, we also offer performance studies under special conditions, such as solubility and phase separation behavior at different temperatures, or comparative analysis of samples with varying molecular weights. If you are interested in our service, please feel free to contact us.

 

Analysis Workflow

1. Sample Reception and Pretreatment: Verify sample information, label, and store appropriately.

2. Basic Analysis: Perform preliminary tests such as appearance, solubility, and moisture content.

3. Composition and Impurity Analysis: Conduct IR, GC, LOD, ROI, and heavy metal testing in accordance with pharmacopeial standards and client requirements.

4. Functional Performance Evaluation: Assess film-forming ability, swelling capacity, and disintegration performance according to application needs.

5. Data Review and Reporting: All results are quality-checked and compiled into a complete report.
