Function and Application


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%.


Toothpaste Grade

CMC has an efficiency of adhesion and molding when used in toothpaste, and stabilizes the quality of toothpaste owing to good compatibleness.

The recommended addition is 0.5-1.5%.


 for oil drilling

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;

             1.4-4.0% used in colored glaze.


Paper Grade

In making paper, CMC is used in making pulp so as to improve the retention rate and increase humidity and strength; when used in surface sizing, CMC can improve internal adhesion, decrease printing dust and enhance printing quality as molding reagent. In paper coating, CMC also helps the dispersion and fluidity of paint, improves appearance of paper and smoothness, upgrades optical performance and printing adaptability.

Addition: 0.3-1.5%.


Detergent Grade

Effectively prevent washes from becoming contaminated after being washed by synthetic detergent.Add 0.5-2 percent only, you can get satisfactory result.Because the action of static between fomite granule with minus charge and CMC molecule with minus charge itself.
