CMC Food Grade Description:
Carboxymethyl 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.

2) CMC Food Grade Application
In foods,Sodium Carboxymethyl Cellulose CMC is used in food science as a viscosity modifier or thickener, and to stabilize emulsions in various products including ice cream. As a food additive, Sodium Carboxymethyl Cellulose CMC has E number E466.
Sodium Carboxymethyl Cellulose CMC is also a constituent of many non-food products, such as personal lubricants, toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing, and various paper products.Sodium Carboxymethyl Cellulose CMC is used primarily because it has high viscosity, is nontoxic, and is generally considered to be hypoallergenic as the major source fiber is either softwood pulp or cotton linter.
Sodium Carboxymethyl Cellulose CMC is used extensively in gluten free and reduced fat food products.
In laundry detergents, Sodium Carboxymethyl Cellulose CMC is used as a soil suspension polymer designed to deposit onto cotton and other cellulosic fabrics, creating a negatively charged barrier to soils in the wash solution.
In Pharmaceuticals,Sodium Carboxymethyl Cellulose CMC is also used in pharmaceuticals as a thickening agent
In the oil-drilling industry as an ingredient of drilling mud, where it acts as a viscosity modifier and water retention agent.
