1. 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. It is also used extensively in gluten free and reduced fat food products.
2. 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.
3. 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.
4. In Pharmaceuticals,Sodium Carboxymethyl Cellulose CMC is also used in pharmaceuticals as a thickening agent, and
5. In the oil-drilling industry as an ingredient of drilling mud, where it acts as a viscosity modifier and water retent.

Package and Storage:
PAC-HV Picture
1. Characteristics:
Sodium Carboxymethyl Cellulose (CMC) is white or yellowish powder that is odorless ,tasteless and non-toxic . It has high hygroscopicity and is soluble in water to form a thick liquid . It is a polyanionic electrolyte and not fermented . It has good heat-stability . resistance to salt and film-forming property . It is a strong emulsifier for fat and oil .
2. Applications
Detergent and mosquito-repellent incense
1. Effectively prevent washes from becoming contaminated after being washed by synthetic detergent .Add 0 . 5-2 percent only,you can get satisfactory result . Because the action of static between fomite granule with minus
charge and CMC molecule with minus charge itself .
2. Make washing liquid more viscous and the effect of washing more stable .
3. Improved toughness of mosquito-repellent incense .Which can prevent from denting and cracking . 4 . Each group of mosquito-repellent incense compatible to achieve better medicine effect .
Building and ceramics
1. At the same time ,it can be control viscosity and floating .
2. CMC can be applied as semi-finished viscosity in ceramics industry , for it can increase plasticity performance .
3. CMC can be used as flowing control matter in ceramics glost substitute ,which has the performance of retain substitute ,to prevent it from getting to tear cicatrice before cooking finish .
Paper coating
CMC is used as paper gluing agent to provide paper with high compatibility ,fine anti-ink osmosis and high was gathering capability .
CMC can help control color paste flowing for paper and during paper variegation .
Toothpaste
1. It has good compatibility with other ingredients
2. Toothpaste body is smooth ,and separating from water or shell and becoming coarse .
3. It has good stability and suitable viscosity , so it makes toothpaste more fresh and pleasant .
4. At the same time ,toothpaste grade CMC has good white appearance ,easy to make clear toothpaste and good rheology .
Textile and Battery
1. CMC can be uses as printing material for dye-trimming industry and it can improve hydrophilic force and osmosis force of dye material ,making dying more even and reducing chromatism .
2. CMC is mainly used in Cr-Ni battery .
3. Packaging
CMC Product is packed in an inner polyethylene bag reinforced with a 3-ply paper bag , or paper barrel or paper box , net weight is 25kg per bag .
4. Transportation and Storage
Protect the product against moisture and damp .
Don't put it together with other chemicals .
