CMC is one of the important raw material in the toothpaste production, it can mix liquid ingredients with solid materials evenly in the toothpaste and makes the toothpaste has a good performance in the molding flow and appropriate viscosity, as well as the brightness and sophistication.
The CMC can be used as the adhesive in the common type of toothpaste which not add special effects additives. Anion CMC is more sensitive in the high concentration of ions, will lower the bonding performance of the CMC. So the high-performance of CMC can not wildly be used in the special effects toothpaste. But if use non-ionic HEC as the Adhesive in the toothpaste, it can enhance the performance of the adhesive to resist high concentrations of ions, and the storage stability is greatly improved, extending the storage time of the toothpaste. The toothpaste manufacturers can use CMC ~ HEC in the high salt toothpaste. The CMC for toothpaste DS = 0.9 to 1.0, the viscosity is the 6500 mPa · s (2% solution, 25 ° C, Brookfield viscosity meter).
