CAS 9004-32-4 cmc powder carboxyl methyl cellulose food grade
Sodium carboxymethyl cellulose is a sodium salt of cellulose carboxymethyl ether. It is an anionic cellulose ether. It is a white or milky white fibrous powder or granule with a density of 0.5-0.7 g/cm3. It is almost odorless and tasteless. Hygroscopicity. It is easy to disperse in water to form a transparent colloidal solution and is insoluble in organic solvents such as ethanol. The pH of the 1% aqueous solution is 6.5-8.5. When the pH is >10 or <5, the viscosity of the cement is significantly lowered, and the performance is optimal at pH=7. For heat stability, the viscosity rises rapidly below 20 °C, and the temperature changes slowly at 45 °C. The long-term heating above 80 °C can denature the colloid and the viscosity and performance are significantly reduced. Soluble in water, the solution is transparent; it is stable in alkaline solution, it is easy to be hydrolyzed when it is acid, and precipitation will occur when the pH is 2-3, and precipitation will occur in the case of polyvalent metal salts.

3. Sodium Carboxymethyl Cellulose/CMC Usage:
(1) Sodium Carboxymethyl Cellulose/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) Sodium Carboxymethyl Cellulose/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) Sodium Carboxymethyl Cellulose/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) Sodium Carboxymethyl Cellulose/CMC for Ceramic :
CMC is used for ceramic embryo, glazing pulp and colored glaze in ceramic industry.
(5) Sodium Carboxymethyl Cellulose/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) Sodium Carboxymethyl Cellulose/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) Sodium Carboxymethyl Cellulose/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.
