  1.39

• Melting Point ：

  225-230 °C

• Solubility ：

  H2O: 50 mg/mL, clear to very faintly turbid, faintly yellow

• Storage Condition ：

  Hypromellose powder is a stable material, although it is hygroscopic after drying.
  Solutions are stable at pH 3–11. Hypromellose undergoes a reversible sol–gel transformation upon heating and cooling, respectively. The gelation temperature is 50–90°C, depending upon the grade and concentration of material. For temperatures below the gelation temperature, viscosity of the solution decreases as temperature is increased. Beyond the gelation temperature, viscosity increases as temperature is i

• Stability ：

  Stable. Solid is combustible, incompatible with strong oxidizing agents.
