Description

Sodium Carboxymethyl Cellulose (CMC)

Sodium Carboxymethyl Cellulose (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.

Appearance

CMC is a white to creamish colored powder consisting of very fine particles, fine granules. As well as, odor less and tasteless and a hygroscopic powder readily dissolves in water to form a colloidal solution. It is insoluble in many organic solvents such as methanol, ethanol, propanol and acetone and so on.

FUNCTIONS & PROPERTIES

Sodium Carboxymethyl Cellulose (CMC) has the following functions and properties:
1) it acts as a thickener, binder, stabilizer, suspending agent and flows 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 is available in three grades: HIGHLY PURIFIED, PURIFIED & TECHNICAL and in many types based on carboxymethyl substitution, viscosity, purity, particle size, and other parameters.**

APPLICATIONS of Sodium Carboxymethyl Cellulose (CMC)

CMC are widely used in Foods, Pharmaceuticals, Cosmetics, Textiles, Papers & Corrugated Boards, Detergents, Paints, Oil Well Drillings, Welding Electrodes, Pesticides, Ceramics, Tobacco, Mosquito Repellent Incense. Also, Explosives, Batteries, Pencils, Leathers & other industries.
