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.

Application:
CMC in Food Industry:
Widely used in frozen desserts, protein food, beverages, icings, dressings, instant noodles, etc.
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.
