Sodium Carboxymethyl Cellulose (also referred as CMC and Carboxy Methyl Cellulose) can briefly be described as an anionic water-soluble polymer produced from naturally occurring cellulose by etherification, substituting the hydroxyl groups with carboxymethyl groups on the cellulose chain.

There are a number of parameters which define the properties of the Sodium Carboxymethyl Cellulose CMC.
√ Purity (active CMC content): inevitably CMC powder is produced with by products that are sodium salts which comes in the product Sodium Carboxymethyl Cellulose content in the product is the purity.
√ Viscosity: one of the most interesting characteristics of the CMC powder is the viscosity which can be from low to high. It is measured mostly by digital viscometers at certain temperatures in different solution rates; such as 1%, 2% or 4%.
√ Degree of Substituion: is the average number of sodium carboxymethyl groups per anhydroglucose unit on the cellulose back bone. This parameter in some application areas is quite important to control in the product.
√ Physical form: the CMC powder can be produced in fine powder to dust-free granule.
Unique Functions
Thanks to its versatility, CMC can provide different functions and that is what it owes for being used in a range of industries.

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.
