Cellulose, a complex carbohydrate found in the cell walls of plants, is the most abundant organic compound on Earth. It is composed of long chains of glucose molecules linked together by covalent bonds, making it both strong and resilient. Despite its abundance, cellulose has historically been difficult to convert into useful products due to its crystalline structure and the presence of protective lignin and hemicellulose layers. However, recent advances in biotechnology and chemical engineering have made it possible to overcome these challenges and unlock the full potential of cellulose.

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.
