Hydroxypropylmethyl cellulose is a cellulose ether with both methyl and hydroxypropyl functional group substitutions. Hydroxypropylmethyl cellulose (HPMC) is a nonionic thermoplastic polymer that dissolves in water to produce a solutions with a wide range in viscosity. It has greater gelling capacity than hydroxypropyl cellulose (HPC) and is more tolerant to salts and additives. HPMC is used as a thickening agent, stabilizer, emulsifier and film forming agent. Aging studies indicate that HPMC has very good stability with negligible discoloration or weight loss (Feller and Wilt 1990).
