Description
Sodium Carboxymethyl Cellulose (SCMC or CMC) or Cellulose Gum is an anionic water soluble polymer; It is derived from cellulose, which is made water soluble by a chemical reaction. The water solubility is achieved by introducing carboxymethyl groups (-CH2-COOH) along the cellulose chain, which makes hydration of the molecule possible.
The chemical name of SCMC is SODIUM SALT OF CARBOXYMETHYL ETHER OF CELLULOSE.
CAS NUMBER: 9004-32-4.
FUNCTIONS & PROPERTIES
Sodium Carboxymethyl Cellulose (CMC) has the following functions and properties:
1) it acts as a thickener, binder, stabilizer, suspending agent and flow controlling agent.
2) It forms fine films that are resistant to oils, greases, and organic solvents.
3) It dissolves rapidly in cold water.
4) Acts as a protective colloid reducing water losses.
5) It is suitable for use in food systems.
6) It is physiologically inert.
7) It is an anionic polyelectrolyte.
These properties and functions make it suitable for use in a broad range of applications in the food, pharmaceutical, cosmetic, paper, and other industries. To serve these diverse industries, CMC are available in three grades: HIGHLY PURIFIED, PURIFIED & TECHNICAL and in many types based on carboxymethyl substitution, viscosity, purity, particle size, and other parameters.
APPLICATIONS
CMC are widely use in Foods, Pharmaceuticals, Cosmetics, Textiles, Papers & Corrugated Boards, Detergents, Paints, Oil Well Drillings, Welding Electrodes, Pesticides, Ceramics, Tobacco, Mosquito Repellent Incense, Explosives, Batteries, Pencils, Leathers & other industries.
