Characteristics of CMC

- Mar 23, 2018 -

Carboxymethyl cellulose is a natural hydrophilic colloid.Sodium carboxymethylcellulose is dispersed in water and then rapidly expands and dissolves.

In the process of stirring, slowly adding carboxymethyl cellulose can hasten dissolution;

In the case of heating, the dissolution rate can be increased by dispersing the carboxymethyl cellulose, but the heating temperature should not be too high, and the appropriate range is 50 c-60 c;

When mixed with other materials, mix solid first, then dissolve, and solubility can be increased.

Organic solvents are not compatible with sodium carboxymethyl cellulose, but are compatible with water, such as ethanol, glycerin, etc., then dissolve, and the dissolution rate will be very rapid.

 

Hygroscopic Properties of Sodium Carboxy Methyl Cellulose

Sodium carboxymethyl cellulose is hygroscopic, and its moisture absorption level is related to atmospheric temperature and relative humidity.When balanced, it will no longer absorb water.
