CMC Sodium Carboxy Methyl Cellulose Powder Detergents Stabilizer For Food Beverage

Sodium Carboxymethyl Cellulose, CMC Sodium Salt

Structure:

CMC is a derivative of the regenerated cellulose [C6H10O5]n with hydroxy-acetic acid (hydroxyethanoic acid) CH2(OH)COOH or sodium monochloroacetate (Na[ClCH2COO]). The CMC backbone consists of D-glucose residues linked by -1,4-linkage. It has 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 .

Properties:

CMC is a white or lightly yellow powder with no odor, flavor, or poisonous properties. It is hygroscopic and dissolves well in hot or cold water, forming a viscous solution. It is not soluble in organic solvents like methanol, ethanol, chloroform, and benzene. The functional properties of CMC depend on the degree of substitution of the cellulose structure (i.e., how many of the hydroxyl groups have been converted to carboxymethylene groups in the substitution reaction), as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents. It is commonly used as a viscosity modifier or thickener and to stabilize emulsions in various products, both food and non-food-related. It is mainly used because it has a high viscosity, is nontoxic, and is generally considered to be hypoallergenic .

Uses:

Carboxymethyl cellulose (CMC) is used in applications ranging from food production to medical treatments.It is commonly used as a viscosity modifier or thickener and to stabilize emulsions in both food and non-food products. It 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. It is also used in non-food products which include products such as toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing, reusable heat packs, various paper products, filtration materials, synthetic membranes, wound healing applications, and also in leather crafting to help burnish edges .
