Carboxymethyl cellulose (CMC) supplier Distributor Manufacturer in chennai Taminadu india

Carboxymethyl cellulose (CMC) or cellulose gum or tylose powder  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.

uses

CMC is used in food under the E number E466 or E469 (when it is enzymatically hydrolyzed) as a viscosity modifier or thickener, and to stabilize emulsions in various products including ice cream. It is also a constituent of many non-food products, such as toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing, reusable heat packs, and various paper 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. CMC is used extensively in gluten free and reduced fat food products. 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. CMC is used as a lubricant in artificial tears.

CMC is also used as a thickening agent, for example, in the oil-drilling industry as an ingredient of drilling mud, where it acts as a viscosity modifier and water retention agent.

Knitted fabric made of cellulose (e.g. cotton or viscose rayon) may be converted into CMC and used in various medical applications.

Device for epistaxis (nose bleeding). A poly-vinyl chloride (PVC) balloon is covered by CMC knitted fabric reinforced by nylon. The device is soaked in water to form a gel, this is inserted into the nose and the balloon inflated. The combination of the inflated balloon and the therapeutic effect of the CMC stops the bleeding.
Fabric used as a dressing following ear nose and throat surgical procedures.
Water is added to form a gel, and this gel is inserted into the sinus cavity following surgery.
Insoluble microgranular CMC is used as a cation-exchange resin in ion-exchange chromatography for purification of proteins.Presumably, the level of derivatization is much lower, so the solubility properties of microgranular cellulose are retained, while adding sufficient negatively charged carboxylate groups to bind to positively charged proteins.

CMC is also used in ice packs to form a eutectic mixture resulting in a lower freezing point, and therefore more cooling capacity than ice.

Aqueous solutions of CMC have also been used to disperse carbon nanotubes. The long CMC molecules are thought to wrap around the nanotubes, allowing them to be dispersed in water. In conservation-restoration, it is used as an adhesive or fixative (commercial name Klucel).

CMC is used to achieve tartrate or cold stability in wine. This innovation may save megawatts of electricity used to chill wine in warm climates. It is more stable than metatartaric acid and is very effective in inhibiting tartrate precipitation. It is reported that KHT crystals, in presence of CMC, grow slower and change their morphology. Their shape becomes flatter because they lose 2 of the 7 faces, changing their dimensions. CMC molecules, negatively charged at wine pH, interact with the electropositive surface of the crystals, where potassium ions are accumulated. 
In veterinary medicine, CMC is used in abdominal surgeries in large animals, particularly horses, to prevent the formation of bowel adhesions.

Cdes requiring extra flexibility, e.g. for use with silicon-coMC is sometimes used as an electrode binder in advanced battery applications (i.e. lithium ion batteries), especially with graphite anodes. CMC's water solubility allows for less toxic and costly processing than with non-water soluble binders, like the traditional polyvinylidene fluoride (PVDF), which requires toxic n-methylpyrrolidone (NMP) for processing. 

Culinary uses

CMC powder is widely used in the ice cream industry. It is used to make ice creams without churning mechanism or extreme low temperatures thereby eliminating the need of the conventional churners or salt ice mixes. CMC is used in bakery products like breads and cake preparation. The use of CMC gives loaf a much improved quality at a reduced cost to the baker economizing on the fat component. CMC is also used as an emulsifier in producing high quality biscuits. Due to CMC, fat disperses uniformly in the dough and hence CMC improves the release of the dough from the moulds and cutters to achieve well-shaped biscuits without any distorted edges. It can help to reduce consumption of egg yolk or fat used in making biscuits, thus achieving economy. Use of CMC in candy preparation ensures smooth dispersion in flavour oils, improves texture & quality. They are used in chewing gums, margarines and peanut butter as emulsifier, also it is used in leather crafting to burnish the edges.
