HPMC (Hydroxypropyl methyl cellulose) is a water-soluble polymer made from cellulose modified with hydroxypropyl groups. It is used as a thickener, emulsifier and stabilizer in foods, pharmaceuticals and cosmetics. HPMC is produced by treating methyl cellulose with propylene oxide. The end result is a white, odorless and tasteless powder. Hydroxypropyl methyl cellulose is very similar to methyl cellulose, but it is more soluble in water and has a higher viscosity. HPMC has many uses, such as a thickener (to replace cornstarch), a stabilizer (to prevent ingredients from separating or settling), a binder (to hold ingredients together), or an emulsifier (to mix two substances that do not dissolve well into each other).
In the food industry, HPMC is used as a food additive in various products such as sauces, soups, and dairy products
