Sodium Carboxymethylcellulose CMC is a water soluble anionic polymer derived from
cellulose.It is comprised of the woody parts and cell walls of plants. It is
cellulose ether produced by reacting alkali cellulose with sodium
mono-chloracetate under controlled conditions.

- Physical
It occurs as a white-to-cream colored powder or granules. It is
hygroscopic and insoluble in most solvents. The powder will be
nearly odorless and transparent in solution.- Solubility
CMC is a water-soluble polymer soluble in either hot or cold
water. It is insoluble in organic solvents but will dissolve in
miscible solvents as ethanol or acetone. CMC viscosity will not
increase with temperature.- Degree of Substitutions
Typically the range of substitution is from .3 – 1.4. The sodium
content will increase with the substitution range thus improving
the compatibility with other soluble salts and non solvents.
Generally the compatibility will increase to ten times the
substitution rate.- Viscosity
Viscosity ranges are from 50–8000 cps; with any desirable
viscosity in between. Most concentrations are based either on a
1 or 2% solution and measured on a Brookfield LVT Viscometer.
Point of complete hydration is achieved faster with finer mesh
grades but care in dispersion is required. Thixotropic behavior is
seen with medium and high grades of CMC (DS of 0.4–0.7) but
grades with “smooth-flow” characteristics are commercially available.

CMC is used for many different food, pharmaceutical and technical
applications. These uses are based mainly on its reaction with water
content in the finished product. It is used alone or in conjunction with
other components in the system to create thickening, water-binding,
suspension, stabilizing and emulsifying characteristics.- Qualities
