Toothpaste Grade CMC (Sodium Carboxymethyl Cellulose)


CMC is used as thickening additive in toothpaste toprevent the solid-liquid separation of toothpaste, which makes the toothpastehas a certain viscosity and consistency and the paste is smooth and fine, andit improves the taste of toothpaste.

In toothpaste, a variety of salt electrolytes areusually added, and the salt tolerance of CMC can effectively prevent theelectrolyte from damaging the paste viscosity, thinning and solid-liquidseparation.

CMC has the good pseudoplastic that is beneficial toimprove the production efficiency of toothpaste. It is more convenient tosqueeze out when you use.

Furthermore, it helps the powders andliquids emulsify evenly to become the stable soliquoid, and plays the extremelyimportant role in stability and diffusivity.

CMC is mainly used as thickener in toothpaste toprevent its solids from liquids. It makes the toothpaste thickness, strip shapeand good frame and not be runny, soft and thin on the toothbrush, andmeanwhile, it keeps brightness and smoothness.
