What's the difference between sodium carboxymethyl cellulose

CMC is the abbreviation of carboxymethyl cellulose. It is a natural product derived from cellulose. It has many advantages that natural gum and grain size do not have. It is soluble in water and can significantly increase the viscosity of the solution. It has the functions of thickening, dispersion, emulsification, suspension, stabilization and protection of colloids.
 
The main chemical reactions of CMC are alkalization of cellulose and alkali to alkali cellulose and etherification of alkali cellulose and monochloroacetic acid.
 
From the above reaction, I think the landlord should understand that sodium carboxymethyl cellulose is not introduced on the basis of carboxymethyl cellulose. In fact, alkali cellulose has been formed in the process of alkalization and then synthesized by introducing carboxymethyl groups.
 
They are actually the same thing.
