carboxyl methyl cellulose cmc powder food grade
CMC is widely used in frozen desserts, protein food, beverages, icings, dressings, instant noodles, etc.
Properties
1. Thickening: CMC can produce high viscosity at low concentration. It also acts as lubricant.2. Water retention: CMC is a water binder, helps increase shelf life of food.3. Suspending aid: CMC acts as emulsifier and suspension stabilizer, particularly in icings to control ice crystal size.4. Film forming: CMC can produce a film on the surface of fried food, eg. instant noodle, and prevent absorption of excessive vegetable oil.5. Chemical stability: CMC is resistant to heat, light, mold and commonly used chemicals.6. Physiologically inert: CMC as a food additive has no caloric value and can not be metabolized.
CMC in Ceramic Industry
1.CMC for ceramics features uniform distribution of substituents (carboxymethyl group) on the cellulose backbone. It produces fewer gel granules in glaze formulation.2. It contains no colored impurity and is **0% combustible under firing condition, to ensure clean ceramic glaze.3. It can stabilize physical and chemical property of glaze formulation.4. It can improve glaze adhesion and reduce glaze cracking.5. It facilitates formation of a smooth dense glaze layer.6. It can improve the rheological property of glaze formulation.7. The glaze viscosity is proportional to the concentration of CMC added.
CMC in Oil Drilling Industry
1, high degree of substitution, good uniformity of substitution .
2, high transparency, viscosity and water loss can be controlled .
3, suitable for fresh water, sea water, saturated brine slurry .
4, stabilize soft soil structure, prevent collapse of wall of a well .
5, can improve mud-making volum, reduce filteration loss .
6, has excellent performance in drilling of oil .
Uses: CMC is widely used in oil drilling, textiles, pharmaceutical, paint, ceramics, daily-use chemicals, paper and other industries. It can be used as suspending agent, water loss reducer, sealant, glueing agent, thickener, emulsifying agent, stabilizator, dispersing agent, etc.
