High Quality Food Grade Sodium Carboxyl Methyl Cellulose CMC
1.Simple Introduction of Sodium Carboxymethyl Cellulose/CMC
Natural cellulose is the most widely distributed and most abundant polysaccharide in the natural world and has a rich source. Current cellulose modification technologies are mainly focused on etherification and esterification. Carboxymethylation is a type of etherification technology. After the carboxymethylation of cellulose, carboxymethyl cellulose (CMC) is obtained. The aqueous solution has functions of thickening, film formation, adhesion, water retention, colloid protection, emulsification and suspension, and is widely used in petroleum, food, and medicine. The textile, paper and paper industries are among the most important cellulose ethers.
Carboxymethyl cellulose sodium (CMC) is an anionic cellulose ether, the appearance of white or yellowish flocculent fiber powder or white powder, odorless, tasteless, non-toxic; soluble in cold water or hot water, the formation of a certain viscosity Transparent solution. The solution is neutral or slightly alkaline, insoluble in organic solvents such as ethanol, ether, isopropanol, acetone, and soluble in 60% ethanol or acetone. Hygroscopicity, light and heat stability, viscosity decreases with increasing temperature, the solution is stable at pH 2 to 10, PH is less than 2, there is a solid precipitation, PH value is higher than 10 viscosity decreases. The discoloration temperature was 227°C, the carbonization temperature was 252°C, and the surface tension of the 2% aqueous solution was 71mn/n.

3.Sodium Carboxymethyl Cellulose/CMC Application
(1) CMC for 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.
(2) CMC for Toothpaste Grade:
CMC has an efficiency of adhesion and molding when used in toothpaste, and stabilizes the quality of toothpaste owing to good compatibleness.
(3) CMC 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.
(4) CMC for Ceramic :
CMC is used for ceramic embryo, glazing pulp and colored glaze in ceramic industry.
(5) CMC for paper making:
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.
(6) CMC for detergent :
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. Make washing liquid more viscouse and the effect of washing more stable.
(7) CMC for for other industries:
As coagulant, water retaining, thickener and binder, CMC is also used in paint, carpet gum, mosquito coil incense, tobacco, electric welding, textile, battery, printing and others.
