    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).

    The food sector also finds HPMC useful as a food additive, where it functions as a stabilizer, emulsifier, and thickening agenthpmc meaning. It's often used in ice cream to prevent ice crystal formation, in jams and jellies to maintain their texture, and in low-fat products to replicate the mouthfeel of fat.
