Carboxymethyl Cellulose Sodium [ 9000-11-7 ]
- Appearance
- White powder
Physical properties:
Sodium carboxy methyl cellulose (CMC) of anionic type cellulose ethers, appearance is white or light yellow or white floe fiber powders powder, odorless, avirulent insipidity, Soluble in cold or hot water to form a certain viscosity of transparent solution. Solution for neuter or slightly alkaline, insoluble in ethanol, ethyl ether, isopropyl alcohol, acetone, etc, soluble in water 60% alcohol or acetone solution. Has hygroscopic, stable, the viscosity of warmth with temperature decreased, while the solution in PH 2 ~ 10 stability, PH less than 2, have solid exhalation, PH value is higher than 10 viscosity reduced. Discoloration temperature ℃, carbonization temperature 252 227 ℃, 2% aqueous surface tension 71mn/n.
