| Description: | It is a nonionic cellulose ether, no odor and smell, soluble in cool water, glacial acetic acid, and some organic solvents and water mixtures, not soluble in hot water, ethanol, ether, acetone. Its aqueous solution is of surface activity, high transparency and stability, when heated to certain temperature, the solution becomes cloudy and gelling quickly, however, the solution become clear again after cooling. HPMC has different types varying from its gelling temperature. The solubility is differed from its viscosity, the lower the viscosity, the higher the solubility. However, the solubility in water is not subject to pH value of its aqueous solution. The lower methoxyl content of HPMC, the higher gelling temperature, the lower solubility and surface activity. | |
