Introduction

Sodium carboxymethyl cellulose (CMC-Na) is a carboxymethylated derivative of cellulose, which is the most important ionic cellulose gum. It is an anionic polymer compound made from reaction of natural cellulose, caustic alkali and monochloroacetic acid, whose molecular weight varies from several thousand to millions. It is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easily to disperse in water to form a transparent colloidal solution.

Feature

1. Viscosity: CMC increases the viscosity of aqueous solutions even at low concentrations.
2. Solubility: CMC is very soluble in cold water, forming a viscous solution.
3. Biodegradable: Since CMC is derived from cellulose, it is biodegradable and environmentally friendly.
4. Grades: CMC is available in different grades, depending on the degree of substitution (the extent to which carboxymethyl groups are added to cellulose) and viscosity.
