Cmc-na for short, white to pale yellow powder, granular or fibrous substance, strong hygroscopicity, easily soluble in water, and the solution is a high-viscosity liquid when it is neutral or alkaline. stable to medicines, light and heat. however, the heat is limited to 80°c, and if heated for a long time above 80°c, the viscosity will decrease and it will be insoluble in water. it turns brown when heated to 190-205°c, and carbonizes when heated to 235-248°c. its solubility in water depends on the degree of substitution. insoluble in acid and alcohol, no precipitation in case of salt. it is not easy to ferment, has strong emulsifying power to oil and wax, and can be stored for a long time.
