Sodium Carboxymethyl Cellulose (CMC) (CAS 9004-32-4), also known as Carboxymethylcellulose Sodium or Cellulose Gum, is a water-soluble cellulose derivative widely used as a thickener, stabilizer, binder, suspending agent and rheology modifier.
CMC is produced by chemically modifying cellulose to introduce carboxymethyl groups. The sodium salt form provides good water solubility and functional properties, making it suitable for a wide range of industrial applications.
Sodium Carboxymethyl Cellulose is widely used in the food, pharmaceutical, personal care, detergent, textile, paper, ceramics, oil drilling and other industries. Its viscosity, degree of substitution and purity can vary depending on the application and product grade.
