Chemical Composition and Key Properties of HPMC

  • Chemical Structure: HPMC is made by replacing cellulose’s hydrogen atoms with hydroxypropyl and methyl groups, leading to a non-ionic, stable compound.
  • Water Solubility: It dissolves easily in water, making it ideal for applications requiring stable dispersions or consistent texture.
  • Thermal Gelation: HPMC’s gelation upon heating offers valuable control in pharmaceutical and construction uses.
  • pH Stability: With stability across a wide pH range, HPMC performs well in diverse environments, from construction materials to drug formulations.
