CarboxylMethyl Cellulose toothpaste grade
CMC is mainly used as a thickener in toothpaste to prevent the separation of friction agents, making the toothpaste have a certain viscosity and the paste form strips.
It endows toothpaste with good formability, ensuring it does not collapse or become thin when attached to a toothbrush. Make the paste smooth and fine .
How to judge the quality of carboxymethyl cellulose?
When users in the purchase or use, can from the following several parameters to judge the quality of the CMC, degree of substitution (DS) : to determine the solubility and viscosity, usually between 0.6 ~ 1.2 as optimal viscosity level: depending on the specific use choice in high and low viscosity (like food grade is 200 ~ 800 mpa. S) purity: The lower the impurity content, the better the usage effect. The requirements are even higher in the food and pharmaceutical fields .
