Sodium carboxymethyl cellulose (CMC-NA) is a kind of organic matter, chemical formula is [C6H7O2(OH)2OCH2COONa] N, CMC is the carboxymethylated derivative of cellulose, is the most important ionic cellulose glue. Sodium carboxymethyl cellulose is usually made of natural cellulose and caustic soda and a chloroacetic acid reaction after the preparation of an anionic polymer compound,molecular weight from thousands to millions. Cmc-na is a white fibrous or granular powder, odorless, tasteless, hygroscopic, easy to disperse in water to form a transparent colloidal solution.

Application
Detergent grade CMC:
CMC can be used as THICKENER / thickening agent for liquid detergents, thickening agent for soap.
Detergent grades are mainly used in powder and cream type for detergent production, as well as in soap making industry.
With the character of emulsifying and gel protection, CMC will produce the anion during washing and it makes the washed surface and the dirt granule be negatively charged. It prevents re-sticking of the dirt which will be removed by detergent during the cleaning rinsing process. So, the dirt granule has the phase separation property in aqueous phase, and has the repellency with the washed material surface of solid phase. Place dirt then deposit on the washed material, and it can make the white textile keep the whiteness and colored textile bright. CMC can replace hydroxyethyl cellulose (HEC) and Hydroxy propyl methyl cellulose (HPMC) as THICKENER for liquid detergents, which can reduce production cost.
In making soap, adding an appropriate amount of CMC helps to greatly improve the quality of soap. It enables soap to be pliable and flexible and thus convenient for pressing and processing.
The different types of detergent grades of CMC are produced in the limits of detergent grade specifications but they will be divided into different variations due to customer demands. The customer satisfaction, price sensitivity and other expectations are fully covered by these variations.
CMC PAC Oil Drilling Grade:
CMC and PAC can reduce water loss, and increase viscosity in drilling fluid, cementing fluid and fracturing fluid. They play the roles of protecting the wall of well, taking drilling trifles, protecting drilling bit, preventing mud loss and increasing drilling rate.
Usage: add to mud directly or glue solution preparation.
Addition: 0.1-0.3% in fresh water mud; 0.5-0.8% in salt water mud.
CMC Food Grade:
CMC is widely used in food industry, it play the roles of taste improvement, thickening and stabilization when used in various kinds of dairy drinks and seasonings. As an additive of molding, taste improvement, anti-fragmentation, water retaining and tenacity strengthening, CMC is also used in ice cream, bread, cake, biscuit, instant noodle and fast paste foods.
The recommended addition is 0.3-1.0%.
