Sodium carboxymethyl cellulose is an anionic cellulose ether with white or slightly yellow flocculent fibrous powder or white powder in appearance, odorless, tasteless and non-toxic; easily soluble in cold or hot water to form a transparent solution with a certain viscosity , the solution is neutral or slightly alkaline; insoluble in organic solvents such as ethanol, ether, isopropanol, acetone, etc., 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 value of 2-10, the PH value is lower than 2, there is solid precipitation, and the PH value is higher than 10, the viscosity decreases. The discoloration temperature is 227℃, the carbonization temperature is 252℃, and the surface tension of 2% aqueous solution is 71mn/n.
This is the physical property of sodium carboxymethyl cellulose, how stable is it?
The physical properties of sodium carboxymethyl cellulose are very stable, so it presents a long-lasting white or yellow powder. Its colorless, odorless and non-toxic properties can be used in various occasions, such as the food industry, chemical industry, etc.; At the same time, it has very good solubility and can be dissolved in cold water or hot water to form a gel, and the dissolved solution is neutral or weakly alkaline, so it can be used in a wide range of applications and brings better effects.
It is precisely because sodium carboxymethyl cellulose is very soluble that it can be used in many occasions in production and life. Of course, its physical properties are very stable, and the benefits it can bring will be extremely obvious, allowing us to enjoy a different feeling.
