CMC FG3000

KimaCell® CMC FG3000 sodium carboxymethyl cellulose is the most important ionic cellulose gum. Sodium carboxymethyl cellulose is usually an anionic macromolecular compound prepared by reacting natural cellulose with caustic soda and monochloroacetic acid, with molecular weight ranging from thousands to millions. The main chemical reactions of CMC are the alkalization of cellulose and alkali to alkali cellulose and the etherification of alkali cellulose and monochloroacetic acid.

Step 1: Alkalization: [C6H7O2 (OH) 3] n+nNaOH → [C6H7O2 (OH) 2ONa] n+nH2O

Step 2: Etherification: [C6H7O2 (OH) 2ONa] n+nClCH2COONA → [C6H7O2 (OH) 2OCH2COONA] n+nNaCl

KimaCell® CMC FG3000 sodium carboxymethyl cellulose is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easy to disperse in water to form a transparent colloidal solution.
