Product Name: Food Grade CMC 

CAS NO.: 9004-32-4 

General Introduction: 
Sodium carboxymethylcellulose (CMC) is made from natural cotton fibers or wood pulp, through etherification, purification and drying process to made anionic cellulose ether. Sodium carboxymethylcellulose (CMC) appears as white powder or granules, with good water solubility, having the functions of thickening, stabilizing emulsifying and suspending in aqueous solution. 

Application in Food Industry: 
In the food industry CMC used as a good emulsion stabilizer and a thickener, it can also improve the flavor of the food and extend the storage time. It can be widely used in the production of ice-cream, jelly, beverage, bread, yogurt, noodles, biscuit and other flour products. 

Application in drilling field: 
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 volume, reduce filtration loss. 
6. Has excellent performance in drilling of oil.
