  • The etherification of cellulose disrupts the hydrogen bonding and the resulting compounds are not ionised and more water soluble. The EFSA ANS Panel (2018) concluded that modified celluloses including ethyl and methyl, hydroxypropyl celluloses, would not be absorbed intact and not fermented in the gastrointestinal tract of animals (rat) or humans; they are excreted essentially unchanged mainly via the faeces (more than 90% of the administrated doses), while only minor amounts of metabolites and derived-products are excreted via urine or expired air (as 14CO2) and there is no indication for accumulation in the body.

  • One of the key advantages of HPMC is its versatility, allowing it to be adapted to a wide range of applications. Its chemical structure can be modified by adjusting the degree of substitution, resulting in different viscosity grades and functionalities.

  • In the next stage, the alkali cellulose undergoes etherification, where it reacts with a mixture of propylene oxide and methanol in the presence of a catalyst. Propylene oxide adds hydroxypropyl groups to the cellulose backbone, while methanol introduces methyl groups. The ratio of these two reagents determines the properties of the final HPMC product, such as its viscosity and solubility. The process is carefully controlled to achieve the desired characteristics for specific end-use applications.
  • In pharmaceutical formulations, the solubility of HPMC is an important factor to consider when designing drug delivery systems.

  • Several factors influence the gelation temperature of HPMCP, including its molecular weight, substitution pattern, and concentration. Higher molecular weight HPMCP generally exhibits higher gelation temperatures, resulting in slower drug release rates Higher molecular weight HPMCP generally exhibits higher gelation temperatures, resulting in slower drug release rates Higher molecular weight HPMCP generally exhibits higher gelation temperatures, resulting in slower drug release rates Higher molecular weight HPMCP generally exhibits higher gelation temperatures, resulting in slower drug release rateshpmc gelation temperature. Additionally, the degree and type of substitution on the cellulose backbone can affect the gelation properties, with more hydrophilic substituents leading to lower gelation temperatures.
  • 4. Cost-Effective HPMC is relatively inexpensive compared to other thickeners and modifiers, making it a cost-effective option for construction projects.
  • The China HPMC Factory A Pioneer in Pharmaceutical Excellence
  • In the construction industry, hydroxypropyl methylcellulose is utilized as a thickening agent, binder, and water retention agent in cement-based products such as mortar, grouts, and renderings. Its ability to improve workability, increase adhesion, and reduce water segregation in construction materials makes it an essential additive for achieving high-quality and durable structures. The price of HPMC in the construction industry is justified by its contribution to the performance and longevity of building materials.
  • Moreover, the degree of substitution, which refers to the average number of substituted hydroxyl groups per glucose unit, plays a role in determining the hydrophilicity of the polymer. A higher degree of substitution typically leads to increased water uptake and faster gelation, which is essential for controlled-release formulations.
  • In the construction industry, HPMC thickens mortar, rendering it more workable and improving its cohesive properties. It also enhances the water retention capability, reducing the need for excessive water during application. This results in better durability and reduced cracking of the final product.
