Properties: sodium carboxymethylcellulose (CMC), a carboxymethylated derivative of cellulose, also known as cellulose glue, belongs to anionic cellulose ether and is the main ionic cellulose glue. It is usually an anionic polymer compound prepared by the reaction of natural cellulose with caustic soda and monochloroacetic acid. The molecular weight of the compound ranges from thousands to millions.

Detergent:with the character of emulsifying and gel protection, CMC will produce the anion during washing and it makes the washed surface and the dirt granule be negatively charged. So, the dirt granule has the phase separation property in aqueous phase, and has the repellency with the washed material surface of solid phase. Place dirt then deposit on the washed material, and it can make the white textile keep the whiteness and colored textile bright.
