CMC/Sodium Carboxymethyl Cellulose
Carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose.
CMC is white or yellowish powder, granular or fibrous solids, odorless, tasteless, non-toxic. CMC has a thickening, dispersing, suspending, adhesive, film, protective colloid and moisture protection and excellent performance, widely used in food, medicine, toothpaste,liquid detergents cosmetic,welding rod,mosquito coin,tobacco,building and other industries.
1.CMC Food Grade
1.Sodium Carboxymethyl Cellulose (CMC)is white or yellowish powder that is odorless, tasteless and non-toxic.
2. It has high hygroscopicity and is soluble in water to form a thick liquid.
3. It is a polyanionic electrolyte and not fermented.
4. It has good heat-stability, resistance to salt and film-forming property.
5. It is a strong emulsifier for fat and oil .

( in 2% solution at 25 centigrade )
Due to water-solubility, film making ability and binding characteristic, CMC is being used in sizing of yarns in warping. Also, CMC with high viscosity levels are used in printing fabrics; either with sodium alginate or replacing it.
In oil industry, CMC is being used together with barite bentonite, and clay in order to prepare drilling muds, which helps controlling suspension, and getting out the sand in the drilling process.
Glue and Adhesive Industry:
By making use of water solubility and binding properties, CMC is used as glue for wallpaper applications, and is also used in leather industry too.
CMC is used in paper industry for binding the ingredients, and for increasing the strenght of paper. Some purified and technical grades are also used for smoothing the surface of paper, which means better printability and quality.
It is used in paints to control the flow property of paints.
CMC can be used with plaster and cement. The main objective is to prevent early freezing; that way, it becomes quite easy to work on plaster in a longer period.
CMC is used in detergent industry widely due to its property of getting the dirt particules with the rinsing water. In cream detergents, it prevents the drying of surface and CMC can hold the water (moisture) for a long time.
