Methylcellulose Analysis Service | Pharmaceutical Excipient

MtoZ Biolabs provides Methylcellulose Analysis Service that offers comprehensive testing and systematic evaluation of this widely used non-ionic cellulose ether. Methylcellulose (MC) is produced by etherification of natural cellulose with methoxy groups, typically appearing as a white or off-white fibrous or granular powder. It dissolves readily in water to form a transparent or slightly turbid colloidal solution, while remaining insoluble in ethanol, chloroform, and ether. With its thickening, stabilizing, film-forming, and binding properties, MC plays an important role in pharmaceutical formulations and is also used in food, cosmetics, and building materials. As excipients become increasingly central to drug development and quality control, systematic analysis of MC is essential to ensure consistent quality and regulatory compliance.

Services at MtoZ Biolabs

MtoZ Biolabs offers a multi-dimensional evaluation program for MC that spans physicochemical and functional properties:

● Structure and Composition Analysis: Determination of substitution degree and molecular weight distribution using spectroscopic and chromatographic techniques.

● Solubility Testing: Evaluation of solubility performance under various conditions, including clarity and gel characteristics in aqueous systems.

● Viscosity and Rheological Performance: Repeated viscosity testing with viscometers to provide reliable mean values that reflect stability.

● PH and Moisture Assessment: pH measurement and loss on drying under controlled conditions to characterize physicochemical traits.

● Impurity Profiling: Detection of residual solvents, heavy metals, and microbial limits to ensure compliance.

● Functional Property Evaluation: Investigation of thermal gelation, thickening ability, and film-forming capacity to support formulation research.
