Premium Methyl Cellulose MC Powder China Factory and Reliable Suppliers
Methyl Cellulose (MC) is a high-performance water-soluble polymer derived from natural cellulose, engineered to provide exceptional thickening, film-forming, suspension, and emulsifying properties. As a non-ionic chemical agent, it is characterized by its unique thermal gelation properties, remaining stable at room temperature while forming a reversible gel at elevated temperatures, making it an indispensable additive across diverse industrial sectors.
Widely utilized in the pharmaceutical, food, cosmetics, construction, and agricultural industries, our Methyl Cellulose is produced under strict quality controls to meet international standards, including the Chinese Pharmacopoeia. Whether used as a binder for tablets, a stabilizer for ocular solutions, or a thickening agent for industrial coatings, MC delivers unmatched consistency and chemical stability across a wide pH range of 2 to 12.

Frequently Asked Questions
Q: What are the primary applications of Methyl Cellulose in construction?
In construction, MC is used as a thickener and water-retention agent in mortars, adhesives, and coatings to improve workability and prevent premature drying.
Q: How does the thermal gelation of Methyl Cellulose work?
MC is soluble in cold water but forms a gel when heated (typically between 80-90°C). This process is reversible, meaning it returns to a liquid state upon cooling.
Q: Is your Methyl Cellulose suitable for pharmaceutical use?
Yes, our MC complies with the 2020 edition of the Chinese Pharmacopoeia (Part IV), making it ideal for use as a tablet binder, disintegrant, or suspending agent.
Q: Which viscosity grade should I choose for water-in-oil emulsions?
Generally, low-viscosity grades such as 55TZ20 are recommended for use as emulsifiers in water-in-oil emulsion systems.
Q: How should Methyl Cellulose be stored to maintain its quality?
It should be stored in a cool, dry place, avoiding direct sunlight, rain, and moisture. It is typically packaged in lined cardboard buckets.
Q: What is the role of MC in eye drop formulations?
MC increases the viscosity of the solution, which prolongs the retention time of the drug on the surface of the eye, thereby improving the therapeutic effect.
