In paper industry, CMC is used for paper coating. It is useful for the dispersing and flowing of the pigments, enhancing the finish and smoothness of the printing quality. It is used for surface sizing to strengthen the paper and reduce the printing dusts. It can increase moisture and improve retention rate in pulping.

There are many kinds of thickener for toothpaste use in chemical industry, but the application of CMC is most extensive. CMC acts as colloid that helps to shape and conglutinate the dense-degree suit and can keep the stable cream body appearance. After CMC fuse deeply the light rate is high, have better flow to change the function and touch to change the function.
