Description: All CP Kelco CMC brands are water-soluble polymers derived from cellulose by introducing carboxymethyl groups on the cellulose backbone. The formed anionic cellulose molecule hydrates and dissolves readily in water.
CMC stands for carboxymethyl cellulose. However, CMC is more correctly the sodium salt of carboxymethyl cellulose. It is derived from cellulose, which is made water-soluble by a chemical reaction. The water-solubility is achieved by introducing carboxymethyl groups along the cellulose chain, which makes hydration of the molecule possible.
CMC has the ability to impart viscosity to aqueous solutions. CMC is pseudoplastic by nature and can show thixotropic and essentially non-thixotropic rheology. By choosing the right cellulose gum type, the formulator has the ability to achieve the desired rheology for any aqueous system, including suspensions and emulsions. Besides controlling the rheology, CMC is known for its excellent water retaining capacity.
