Product Information

Product Name: Carboxymethylcellulose Sodium (CMC-Na)

CAS No.: 9004-32-4

H.S. Code.: 39123100

Description: Carboxymethylcellulose Sodium is a semisynthetic water-soluble polymer in which

CH2COOH groups are substituted on the glucose units of the cellulose chain through an ether

linkage. Carboxymethylcellulose Sodium is the sodium salt of a polycarboxymethyl ether of

cellulose, and it contains not less than 6.5 percent and not more than 9.5 percent of sodium (Na),

calculated on the dried basis.

Specification: Food Grade, Pharmaceutical Grade, Toothpaste Grade, Oil Drilling Grade

---Food Grade---

Items Specification

Appearance White or a little Yellow, Odorless Powder or Granules

Viscosity (2% aqueous solution, 25℃) 400mpa.s – 1200mpa.s, ≥1200mpa.s

Sodium Content 6.5% –9.5%

PH Value 6.5 – 8.0

Chloride (Cl-) 1.8% Max.

Loss on Drying 10.0% Max.

Heavy Metals 0.002% Max.

Arsenic 0.0002% Max.

Iron 0.03% Max.

Ratio of Acid to Viscosity 0.82 Min.

Ratio of Salt to Viscosity 1 Min.

Enterobacterias 100cfu/g Max.

Usage: Carboxymethylcellulose Sodium can increase the viscosity of solution, it is considered

potentially harmless biologically to the human. Therefore it can be used in the thickening,

dispersion, emulsification, suspension and colloid protection of food, medicine, daily chemicals

petroleum, papermaking, textile and construction field.

⑴ The drilling, well-digging of petroleum and natural gas.

a) The CMC slurry can form a filter cake on the wall of well to lower the water loss of well;

b) CMC can help slurry releasing the gas and discharging the broken matter;

c) CMC can prolong the existing period of drilling fluid;

d) CMC drilling fluid is seldom infected by mould, the high PH value and antiseptic are

unnecessary;

e) CMC can be used as flush fluid to reduce the pollutation of soluble-salts;

f) CMC slurry can work well in 150℃;

⑵ Used as sizing agent of cotton, silk, wool, chemical fiber and blending textile.

⑶ Used as smoothing agent and sizing agent of papermaking, 0.1%～0.3% of CMC can increase 40%～

50% of intension, 50% of compression breakage resistance and 4 to 5 times of flexibility.

⑷ Used as dirty adsorbent of detergent, the gel base of toothpaste, thickening agent and

emulsifier of medicine, or used as mine selection.

⑸ Used as adhesive, plasticizer, suspending agent , color fixative of material.

⑹ Used in construction for water-keeping and reinforcement.

⑺ Used as thickening agent, adhesive and shaping agent of jam, juice, fruit juice, cake and ice

cream.

Storage: Store in a well-closed container.
