Sodium carboxymethyl cellulose (CMC) is one of the important raw materials in toothpaste. CMC in toothpaste makes it thixotropic and gives the toothpaste a good skeleton to keep it stable. At the same time, CMC is used as a thickening agent and water retaining agent, giving the toothpaste forming flow and appropriate viscosity, so that it does not collapse, does not dilute, and the paste is smooth and delicate.

The application characteristics of sodium carboxymethyl cellulose (CMC) in toothpaste:

1. High degree of substitution, uniform substitution, so that the paste delicate luster;

2. Salt and acid resistance, enhance product stability;

3. Good water retention ability, so that the paste does not divide water, does not peel, does not reverse rough;

4. A variety of models, giving different rheological properties, thixotropic performance;
