Sodium carboxymethyl cellulose (CMC) is an anionic cellulose ether, with white or slightly yellow flocculent fiber powder or white powder appearance, odorless, tasteless, non-toxic; easily soluble in cold water or hot water, forming a certain viscosity clear solution[2]. The solution is neutral or slightly alkaline, insoluble in ethanol, ether, isopropanol, acetone and other organic solvents, soluble in 60% water-containing ethanol or acetone solution. It is hygroscopic, stable to light and heat, the viscosity decreases with the increase of temperature, the solution is stable at pH 2-10, pH is lower than 2, there is solid precipitation, and the viscosity decreases when pH is higher than 10. The discoloration temperature is 227℃, the carbonization temperature is 252℃, and the surface tension of 2% aqueous solution is 71mn/n.
