thanks! i am confused. it is not this one?

CMC (sodium carboxymethyl cellulose) is a very versatile product, available in many brands and types. It is derived from cellulose, nature's most abundant polymer.

CMC is an anionic water soluble polymer. This determines its basic physical properties: solubility (dissolution behavior), rheology (viscosity) and adsorption on surfaces. An application's properties can be derived from these basic properties.
