  • Carboxymethyl cellulose (CMC) - Nouryon

    CMC is an anionic water soluble polymer based on renewable cellulosic raw material. It functions as rheology modifier, retains water and is an excellent film former. These attributes make it a preferred choice as a bio-based hydrocolloid in multiple applications. We have produced CMC/cellulose gum since 1944 and our brands are recognized worldwide.
