Methylcellulose is a non-ionic cellulose ether, which is produced by etherification by introducing methyl groups into cellulose.
Methylcellulose is a cellulose methyl ether. White or light yellow or light gray small particles, filamentous or powder. Odorless and tasteless, with approximately 27% to 32% of hydroxyl groups present in the form of methoxy groups. Different levels of methyl cellulose have different degrees of polymerization, ranging from 50 to 1000; And its molecular weight (average) ranges from 10000 to 22000 Da, and its degree of substitution is defined as the average number of methoxy groups, which are connected to each glucose anhydride unit on the chain.

Physical and Chemical Properties
1,Appearance: White or quasi-white fibrous or granular powder, odorless and tasteless.
2,Solution: Almost insoluble in ethanol, ether, chloroform (1: 1) in the mixture can form a clear or suspended viscous solution. In 80-90 ºC hot water rapid swelling, cooling after rapid dissolution, water dissolution at room temperature is quite stable, high temperature gel, It undergoes a reversible transition from gel to dissolution after heating and cooling.
3,Characteristics: Excellent wettability, dispersion, adhesion, thickening, emulsifying, water-holding and film-forming, and oil impermeability. The film has excellent toughness, flexibility and transparency. Because it is non-ionic, it can be compatible with other emulsifiers, but it is easy to be salted out and the solution is stable in the range of pH 2-12.
4,Density: 1.3g/cm;Apparent density: 0.25-0.7 g/cm³.
5,discoloration temperature: 190-200ºC.
6,Carbonization temperature: 225-230ºC.
7,Surface tension: 47-53 dyn/cn.
Packaging, storage and transportation precautions:
1,Points for attention in storage and transportation:Avoid the sun and rain,moistureproof.
2,Packing: Round cardboard drum for this product(Inner bag lined with medicinal polyethylene film)Encapsulation.
3,Net weight per unit:12.5kg or 15kg.

Main uses:
Methylcellulose is currently physiologically inert and widely used as a range extender, protective colloid, auxiliary emulsifier, pigment, tablet adhesive, and film-forming agent in drugs, food, and cosmetics.
It can also be used as a matrix for suspension or viscous eye drops, as well as a stabilizer for drugs. It is the main raw material for oral laxatives, mouthwashes, and corneal contact lens wetting liquids,
and is also used as a skeleton material; MC prepares hydrophilic gel matrix sustained-release preparations, and sustained-release preparations with eye-catching film or multi-layer coating film.
Anti enzyme performance: The anti enzyme performance is far superior to starch, with excellent long-term efficacy;
Adhesive performance: It can achieve the best adhesive strength at the most effective dosage, while providing moisture and releasing flavor;
Cold water solubility: It is easy to hydrate very quickly under lower temperature film conditions;
Emulsification performance: can reduce interfacial tension and reduce oil droplet accumulation to achieve better emulsification stability.
Qingfei Anxin is willing to work hand in hand,actively explore and create a better future with people from all walks of life around the world.
Food grade use:
1. Vegetable Cream (Bakery Products)
Enhances baking volume, improves appearance, and creates a more uniform texture. Improves water retention and distribution, thereby extending the shelf life. Enhances the shape and texture of the product without increasing toughness. Superior adhesion improves the strength and elasticity of flour products.
2. Plant-based Meat (Mock Meat)
Safety: Effectively binds various ingredients together, ensuring the integrity of shape and appearance, and providing a hardness and texture similar to real meat.
3. Beverages and Dairy Products
Provides emulsifying properties within a wide temperature range without creating a sticky sensation. In instant coffee, it quickly produces stable foam. Compatible with alcoholic beverages. Provides a thick consistency to milkshakes without masking the taste. Acid stable.
4. Frozen and Fried Foods
Excellent adhesion, can replace many other binders. Maintains the original shape during processing, cooking, transportation, storage, and repeated freezing/thawing processes. Reduces oil absorption during frying and helps retain the original moisture of the food.
5. Protein Casings
Easy to shape in meat products, resistant to breakage during storage and steaming/frying. Safety: Improves texture and has good transparency. Highly breathable and moisture-permeable, preserving its aroma and extending the shelf life.
6. Dessert Additives
Provides good water retention, helps form small and uniform ice crystals for a better texture. Has foam stability and emulsifying properties, thus improving the fullness of desserts. Maintains excellent foam stability during freezing/thawing. Prevents dehydration shrinkage, significantly extending the shelf life of desserts.
7. Seasonings
Unique thermal gelation properties maintain food stability within a wide temperature range. Rapid hydration. Excellent thickening and stabilizing agent. Has emulsifying properties, preventing oil deposition during storage.
