hidroxipropilmetilcellulóz

Hidroxipropilmetilcellulóz, often abbreviated as HPMC, is a non-ionic polymer derived from cellulose. It is a white to off-white powder that is soluble in water and many organic solvents, forming a viscous solution. HPMC is produced by the etherification of cellulose with methyl chloride and propylene oxide. The degree of substitution and molar substitution determines its specific properties.

HPMC finds widespread use as a thickener, binder, film-former, and stabilizer in a variety of industries. In pharmaceuticals, it is employed as an excipient in tablet coatings, controlled-release formulations, and as a viscosity enhancer in eye drops. The food industry utilizes HPMC as a thickener, emulsifier, and stabilizer in products like sauces, dressings, and baked goods. It is also used in construction materials, such as cement mortars and tile adhesives, to improve workability and water retention. Additionally, HPMC serves as a component in personal care products, including shampoos and lotions, for its thickening and conditioning properties. Its versatility and inertness make it a valuable ingredient in numerous applications.
