1. Product Description
Carboxymethylcellulose (CMC) is a nontoxic and tasteless white flocculent powder with stable performance and is easy to dissolve in water. Its aqueous solution is a neutral or alkaline transparent viscous liquid, soluble in other water-soluble adhesives and resins, and insoluble in organic solvents such as ethanol. CMC can be used as binder, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, etc.
Sodium carboxymethylcellulose (CMC), commonly known as "industrial monosodium glutamate", is the most widely used and convenient product among cellulose ethers.
CMC is light yellow, odorless and non-toxic powder. It can dissolve in cold water and hot water, it can form the transparent glue liquid. CMC solution assumes neutrality. It does not dissolve in acid, ethyl alcohol, benzene and so on. It lightly dissolves in methyl alcohol, ether and so on such organic solvent. The solution viscosity increases along with density, and it is of pseudo-plastic flow, light-proof, thermal-proof, water absorbability, non-agglomerate, and anti- salty ability.

3. Application
Textile Industry:
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.
Drilling Insdustry:
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.
Paper Industry:
CMC is used in paper industry for binding the ingredients, and for increasing the strenght of paper. Some purified and technical grades are also usedfor smoothing the surface of paper, which means better printability and quality.
Paint Industry:
It is used in paints to control the flow property of paints.
Construction Industry:
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.
Detergent Industry:
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.
