Properties of Hydroxypropyl Methyl Cellulose

Hydroxypropyl methylcellulose(HPMC) is easily soluble in cold water, but it will encounter difficulty in dissolving in hot water. But its gelation temperature in hot water is significantly higher than that of methyl cellulose. The solubility in cold water is also greatly improved compared with methyl cellulose. Hydroxypropyl methylcellulose(HPMC) is stable to acid and alkali, and
