Thermal stability of HPMC and MHEC is affected by their gel temperature. In general, the gel temperature of HPMC is around 60℃-75℃ depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80℃. Therefore its stability under high temperature is better that HPMC. On the other hand, because there are more hydrophilic groups in the structure of MHEC, it has better hydrophilicity. The water retention rate of MHEC in mortar is a little higher than HPMC at the same dosage of products with the same viscosity.

In the pharmaceutical industry, HPMC is commonly used as a thickening agent, emulsifier, and film-former in controlled-release drug delivery systems. Its ability to control the release of active ingredients in a predictable and consistent manner makes it an ideal choice for extended-release tablets and capsules. Additionally, HPMC is often used as a binder in tablet formulations, helping to improve the compressibility and disintegration properties of the tablets.
