CAS No. : 9004-32-4
Main Physical & chemical Features
Sodium carboxymethyl celluose(CMC-Na)is a anion type linear macromole substances. Features of pure substance: white or ivory, insipidity ,innocuity, fluidity, fibrous powder, freely soluble in cold or hot water to form transparent sticky solution, unique function. It is a very popular chemical and used in many industry, such as Food, Cosmetics, Ceramics, Oil drilling, Paint, Textile and dyeing, Paper and so on.
Food appropriation type CMC has good properties of acid proof, emulsifying and heat stability. Its water solution has high clarity and when used in liquid milk, soy milk, juice milk, peanut milk and acidity beverages like lactic acid and fruit acid, etc., it can make the solution stable with clean taste and suitable for regular bacterium extinguishing technique such as ultra high temperature (UHT) and Pasteurizing. The suggested adding amount is 0.3-0.5%
When used as dispersant and shape forming agent in ice cream, food appropriation type CMC can not only increase the expansion rate of icecream, but also prevent ice crystal and make ice cream with fine taste, better smoothness and good shape. Its suggested adding amount is 0.25-0.35%
The properties of thickening, suspending and salt proof, etc. of food appropriation type CMC can stabilize and even condiments like soy sauce and jam, beverages like eight treasure rice pudding and fruit beverage, and increase their texture. The suggested adding amount is 0.3-0.8%.
Food appropriation type CMC, for its unique shape forming ability and binding ability, can increase tenacity, smooth surface, improve taste and reduce breaking rate in instant noodles, cookies, and deep frozen wheat flour food, etc. The suggested adding amount is 0.25-0.4%.

| Detergent Grade | 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. Make washing liquid more viscouse and the effect of washing more stable. |
| Oil Drilling & Mining Grade | CMC is a high-purity, high-efficiency slurrying agent. It is resistant to salt, base and moisture, compatible with sea water and saturated brine. It is a strong thickener, suitable for in-situ preparation with dry powder. It is used in mining flotation to separate the metals and impurities. It can help to reduce the pollution to the environment. |
| Paint Grade | CMC is a good thickener in the preparation of paint.It is compatible with most surfactants and stabilizers in waterborne system.It improves rheological property of the paint. |
| Toothpaste Grade | CMC has an efficiency of adhesion and molding when used in toothpaste, and stabilizes the quality of toothpaste owing to good compatibleness. |
| Ceramic Grade | CMC for ceramics features uniform distribution of substituents (carboxymethyl group) on the cellulose backbone. It produces fewer gel granules in glaze formulation. It contains no colored impurity and is 100% combustible under firing condition, to ensure clean ceramic glaze. It can stabilize physical and chemical property of glaze formulation. It can improve glaze adhesion and reduce glaze cracking. |
| Medicine Grade | In medicine industry CMC can be used as thickener, stabilizer and water-holding agent for medicine syrup, it can also be used as water holding and dispersing agent for soft paste medicine. Used as disintegration of the tablet, it can control the release of medicine. CMC also can be used as emulsifying oil agent in injection process. |
| Textile Grade | CMC is used as woof trimming agent replacing traditional starch paste material,which can reduce pollution of woof during sizing and desizing.At the same time,CMC can form a membrane on woof which reduces"drop woof" and "decollation" sign. CMC can be used 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. |
| Paper Grade | CMC is used as paper gluing agent to provide paper with high compactability, fine anti-ink osmosis and high was gathering capability. CMC can help control colour paste flowing for paper and during paper variegation. Increase paper strength and flod-resistance and improve stickiness in paper cellulose |
| Tobacco Grade | CMC for cigarette features high purity and fine particle size, suitable for tobacco processing. It can improve the wet tack and film strength of tobacco. The tobacco treated with CMC produces no foreign odor when burned. The ash is grayish white. It dissolves fast and can achieve the desired viscosity in a short time. |
| Mosquito-repellent incense Grade | Every group evenly mixed and able to replace elm wood powder,so it has better formability and smoother surface.Improved toughness of mosquito -repellent incense.which can prevent from denting and cracking. Each group of mosquito-repellent incense compatible to achieve better medicine effect. |
