FOOD INTRODUCTION:

Carboxy methyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose.

APPLICATION:

CMC is used for food, pharmaceutical and dentifrice (toothpaste) applications. An intermediate "semi-purified" grade is also produced, typically used in paper applications.

CMC is also used in pharmaceuticals as a thickening agent. CMC is also used in the oil drilling industry as an ingredient of drilling mud, where it acts as a viscosity modifier and water retention agent. Poly-anionic cellulose or PAC is derived from cellulose and is also used in oilfield practice. CMC is definitely a Carboxylic Acid, where PAC is Ether. CMC and PAC, although they are manufactured from same raw materials (cellulose, amount and type of materials used leads different final products. The first and the leading difference between CMC and PAC exist in radicalization step. CarboxyMethyl Cellulose (CMC) is both chemically and physically distinguished from Polyanionic Cellulose.
