Ethylcellulose Analysis Service | Pharmaceutical Excipient
Ethylcellulose Analysis Service provides systematic evaluation of ethylcellulose, including structure, substitution degree, molecular weight distribution, purity, physicochemical properties, and application performance. These results support pharmaceutical development, excipient quality control, and functional material studies. MtoZ Biolabs ensures accuracy, reproducibility, and compliance through advanced platforms and an experienced team.
Ethylcellulose (EC) is a nonionic cellulose derivative modified by partial hydroxyethylation. With a 1,4-β-glucosidic backbone, it offers excellent film-forming ability, hydrophobicity, and thermal stability, along with non-toxicity and biocompatibility. In pharmaceuticals, EC is widely used for controlled-release coatings and matrix materials. It is also applied in food, coatings, and cosmetics due to its stability and versatility.

Services at MtoZ Biolabs
MtoZ Biolabs provides a full suite of analytical solutions for EC, ranging from fundamental physicochemical characterization to advanced functional assessments. Our Ethylcellulose Analysis Service includes:
● Structure and Substitution Degree Analysis
Using nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), and elemental analysis, we accurately evaluate the degree and distribution of ethyl substitution, which reveals the essential structural features of EC.
● Molecular Weight and Distribution Measurement
Employing gel permeation chromatography (GPC), light scattering, and capillary viscometry, we determine molecular weight and its distribution, providing essential data for predicting material performance.
● Purity and Impurity Detection
High-performance liquid chromatography (HPLC), gas chromatography (GC), and mass spectrometry (MS) are used to analyze residual solvents, byproducts, and potential impurities, thereby ensuring excipient safety and regulatory compliance.
● Physicochemical Property Testing
Solubility, viscosity, softening temperature, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) are included to provide a complete profile of processing behavior and stability.
● Application Performance Evaluation
For pharmaceutical applications, we test film-forming ability, moisture permeability, and release behavior. For other industries, we assess performance in coatings, barrier systems, and reinforcing materials.
