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.
