MSDS … WebIn carboxymethyl cellulose (CMC), some of these OH groups are etherified with a carboxymethyl group, and the degree of substitution (DS) corresponds to the average number of carboxymethyl groups per AGU. The DS is an important CMC parameter, determining, for example, its solubility in water.
Carboxymethyl cellulose is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. Fabrics made of cellulose—e.g. cotton or viscose rayon—may also be converted into CMC.
