lhydroxypropylméthylcellulose

Hydroxypropyl methylcellulose, often abbreviated as HPMC, is a semisynthetic, inert, and viscoelastic polymer derived from cellulose. It is produced by treating cellulose with alkali and then reacting it with methyl chloride and propylene oxide. This modification makes cellulose soluble in water and various organic solvents, a property not inherent to natural cellulose. HPMC is a white to off-white powder that is odorless and tasteless. Its primary applications stem from its ability to thicken, emulsify, bind, and retain water.

In the food industry, HPMC functions as a thickener, stabilizer, and emulsifier, finding use in products like sauces, dressings, and baked goods. It also serves as a binder in pharmaceutical tablets, aiding in their formation and dissolution. Its water-retention properties are valuable in construction materials such as cement, mortar, and tile adhesives, improving workability and preventing premature drying. HPMC is also employed in cosmetics and personal care products as a thickener and film-former in items like shampoos and lotions. Its inert nature and low toxicity make it suitable for a wide range of applications.
