In addition to high degree of substitution, high viscosity and high purity, it is highly saline and temperature resistant due to its even substitution feature. CMC used as adhesive in toothpaste can resist celulose and thus it's viscosity keeps constant. The past compounded with it has a good luster, elasticity and won't be subject dehydration and coarsening. CMC has good whiteness and transparency and will be dispersed in manufacturing process due to its thixotropy with minimum mechanical wear. The paste made is very white, fine and smooth.
