· Control Viscosity and rheology
· Suspending and binding rheology
· Water retention aid
· Crystal growth inhibitor
· Strong, resistant film former
These properties and functions make it suitable for use in a broad range of applications in the food, pharmaceutical, cosmetic, paper, and other industries. Various types based on carboxymethyl substitution, viscosity, particle size, and other parameters.

Each anhydroglucose unit contains three hydroxyl groups, shown in white. By substituting carboxymethyl groups for some of the hydrogens of these hydroxyls, as shown below, sodium carboxymethylcellulose is produced. The average number of hydroxyl groups substituted per anhydroglucose unit is known as the “degree of substitution,” DS. If all three hydroxyls are replaced, the maximum theoretical DS of 3.0 (impossible in practice) results. Idealized Unit Structure of CMC, with a DS of 1.0
