| Description |
Sodium carboxymethyl cellulose (CMC) is a carboxymethylated derivative of cellulose and is the most important ionic cellulose gum. Sodium carboxymethyl cellulose is usually an anionic polymer compound obtained by reacting natural cellulose with caustic alkali and monochloroacetic acid. Sodium carboxymethyl cellulose can form a clear colloidal solution. It is a hygroscopic material that can absorb more than 50% moisture under high humidity conditions. It is also a natural polymer derivative and can be used in detergents, food and textile industries. |
