Carmellose Sodium

Carmellose Sodium

The main measure of the CMC quality index is the substitution degree (DS) and purity. Generally, the CMC properties of different DS is different also, Instead of increasing, solubility enhancement, the solution is the transparency and stability. According to the report, the CMC substitution degree in 0.7-1.2 good transparency, the solution viscosity in the pH value of 6 ~ 9. In order to ensure its quality, besides the choice etherifying agent, must also consider the substitution degree of purity and the influence factors, such as the base and the dosage of etherifying agent relationship between, etherification, moisture content, temperature, the system of values and solution concentration and DH salts, etc.
