  • HPMC is a semi-synthetic polymer derived from cellulose. It's modified to enhance its properties and solubility in a variety of environments. The chemical structure of HPMC includes hydroxypropyl and methyl functional groups, which bestow it with unique characteristics such as film-forming ability, thickening, and gelling properties. Due to these features, HPMC is extensively used in pharmaceutical formulations for tablet coatings, controlled-release applications, and as a stabilizer in suspensions.
