Description of Carboxymethyl Cellulose:
Carboxymethyl cellulose, also call CMC, it’s white or slightly yellow flocculent fiber powder or White powder, odorless, tasteless, non-toxicant anionic water-soluble polymer based on renewable cellulosic raw material.
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.
CMC is soluble in water at any temperature. Because of its highly hygroscopic nature, CMC hydrates rapidly. Rapid hydration may cause agglomeration and lump formation when the CMC powder is introduced into water.
Lump creation can be eliminated by applying high agitation while the powder is added into the water or prelanding the CMC powder with other dry ingredients such as sugar before adding into water.
Application of CMC:
Carboxymethyl cellulose (CMC) or cellulose gum is one of the major ingredients widely used in food industry as thickener, stabilizer, and viscosity modifier in a large number of different types of foods including ice cream, frozen foods, and beverages.
Non-food application of CMC includes its usage in formulations for cleaning products such as detergents, rheology modifiers and co-binders for papermaking, and formulation of oil drilling solvents.
CMC can be used to stabilize palletized iron nanoparticles, which can further be utilized in the dichlorination of contaminated sub surfaces.
It may also be used as a polymeric matrix to form a composite with a crystalline nanofibril for the development of sustainable bio-based polymers. CMC can also bind with a hard carbon electrode for the fabrication of sodium ion-batteries.
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.
Packing and Storage of Carboxymethyl Cellulose:
25kg kraft paper bag with PE inner, or other packing as clients request.
Store in a cool, dry, clean, ventilated environment. Temperature Max. 40°C, with a relative humidity 580%. The product for pharmaceutical and food grade should not be put together with toxic substance and harmful substance or substance with peculiar smell during transportation and storage.
Since the date of production, a preservation period should not exceed 4 years for the industrial product and 2 year for the product for pharmaceutical and food grade.
The products should be prevented from water and package bag damaging during transportation.
