Solubility of Sodium Carboxy Methyl Cellulose

Sodium Carboxy Methyl Cellulose is a natural hydrophilic colloid. Sodium Carboxy Methyl Cellulose particles disperse in water, then immediately swell and dissolve.

1. Under stirring, slowly adding Sodium Carboxy Methyl Cellulose can accelerate the dissolution;

2. In the case of heating, dispersedly adding Sodium Carboxy Methyl Cellulose can improve the dissolution rate, but the heating temperature should not be too high, and the appropriate range is 50 °C-60°C;

3. When mixed with other materials, first mix solids and then dissolve, and in this way the dissolution rate can also be improved.

4. Adding an organic solvent incompatible with Sodium Carboxy Methyl Cellulose but compatible with water, such as ethanol, glycerin and the like, and then dissolving, the dissolution rate will be fast.

Hygroscopic Properties of Sodium Carboxy Methyl Cellulose

Sodium Carboxy Methyl Cellulose has hygroscopic properties, and its moisture absorption level is related to the atmospheric temperature and relative humidity. When reaching the equilibrium, it will no longer absorb moisture.

Hygroscopic Properties of CMC

CMC has hygroscopic properties, and its moisture absorption level is related to the atmospheric temperature and relative humidity. When reaching the equilibrium, it will no longer absorb moisture.
