Carboxy Methyl Cellulose-CMC

Carboxymethyl cellulose, also call CMC, it's white or slightly yellow flocculent fiber powder or white powder, odorless, tasteless, non-toxic; soluble in cold water or hot water to form a certain stick degree transparent solution. Carboxymethyl cellulose-CMC in the pharmaceutical, cosmetic, oil, drilling, paper, textile, printing and dyeing industry, construction and other fields has been widely used in production.

Application: Oil drilling grade CMC used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency.

Application: Detergent grade CMC, when used in liquid, paste detergent, acts as stabilizing agent and thickening agent; When used in detergent powder, CMC can effectively prevent washes from becoming contaminated after being washed by synthetic detergent.

Application: CMC used in textile and dyeing industry as sizing agent and dying adjuvant to make stock limpidity and transparence. It is easy a good stabilizer of the stock and helps to form film. It is easy to desizing.

About Carboxy Methyl Cellulose

Carboxy Methyl Cellulose(CMC) Preparatio:

Carboxy Methyl Cellulose(CMC)is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The functional properties of Fooding Carboxy Methyl Cellulose(CMC) depend on the degree of substitution of the cellulose structure (i.e., how many of the hydroxyl groups have taken part in the substitution reaction), as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents. CMC belongs to food additives.

Carboxy Methyl Cellulose(CMC) Use:
Carboxy Methyl 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, it has E number E466. It is also a constituent of many non-food products, such as K-Y Jelly, toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing and various paper products. It is used primarily because it has high viscosity, is non-toxic, and is non-allergenic.

In laundry detergents it 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. Carboxy Methyl Cellulose(CMC) is used as a thickeners in non-volatile eye drops (artificial tears). Sometimes it is methyl cellulose(CMC) which is used, but its non-polar methyl groups (-CH3) do not add any solubility or chemical reactivity to the base cellulose.
