Sodium Carboxymethyl Cellulose (CMC)


Sodium Carboxymethyl Cellulose (CMC)

Food grade

CMC in Food Industry

CMC is widely used in frozen desserts, protein food, beverages, icings, dressings, instant noodles, etc.


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.


A. Finely distributed molecular weight.
B. High resistance to acid.
C. High resistance to salt.
D. High transparency, low free fibers.
E. Low gel.

Examples of application

Ice cream:
1.CMC can mix freely with milk, sugar, emulsifier and other ingredients.
2. It helps body formation of the ice cream.
3. It helps control ice crystal size and improves mouthfeel.
4. It brings glossy surface to the ice cream.

Dairy products:
1. CMC stabilizes yoghurt and prevents sedimentation.
2. It increases shelf life.
3. It improves mouthfeel.

Ceramic grade

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 100% 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.
