Overview

Description

Sodium carboxymethyl cellulose (CMC) is a carboxymethylated derivative of cellulose and is the most important ionic cellulose gum. Sodium carboxymethyl cellulose is usually an anionic polymer compound obtained by reacting natural cellulose with caustic alkali and monochloroacetic acid. Sodium carboxymethyl cellulose can form a clear colloidal solution. It is a hygroscopic material that can absorb more than 50% moisture under high humidity conditions. It is also a natural polymer derivative and can be used in detergents, food and textile industries.

Features

Strong hygroscopicity, easily soluble in water; High viscosity; Stable to medicine, light and heat; Insoluble in acids and alcohols, no precipitation in the presence of salts; Great emulsifying power for oils and waxes

Application

For food processing, textiles, detergents and pharmaceuticals;Stabilizers for Nanoparticle Preparation;Binders for electrode production
