Carboxymethylcellulose (CMC) Suspending Agent
CAS Number: 9004-32-4
Carboxymethylcellulose sodium (CMC) is a water-soluble cellulose ether used as a thickener, suspending agent, and stabilizer in aqueous agrochemical formulations including SC suspensions, WG wettable granules, and seed treatment slurries. It imparts pseudo-plastic viscosity to prevent sedimentation and caking, while improving spray application uniformity. CMC is compatible with most pesticide active ingredients and is accepted in organic formulation systems.
