- The viscosity of HEC solutions also varies with temperature, with higher temperatures typically leading to lower viscosities. This is because higher temperatures disrupt the interactions between polymer chains, reducing the overall viscosity of the solution. However, the exact relationship between temperature and viscosity can vary depending on the specific characteristics of the HEC polymer.
Hydroxypropyl MethylCellulose has many features such as thickening power, salt discharge performance, pH stability, water retention, excellent film-forming properties, extensive resistance to enzymes, dispersion and adhesion.
Once the cellulose is activated, the hydroxyethylation reaction can take place. Ethylene oxide is added to the activated cellulose under controlled conditions, typically in a closed reactor system. The reaction occurs at elevated temperatures and pressures to ensure that the ethylene oxide effectively reacts with the hydroxyl groups of cellulose, resulting in the substitution of hydroxyethyl groups into the cellulose backbone. The reaction time, temperature, and ratio of reagents are meticulously controlled to achieve the desired degree of substitution, which influences the solubility and viscosity of the final product.

HPMC Grades and Their Viscosity Profiles
Iincompatibility of gelatin capsules with lactose is well known, and HPMC performs well in this respect. In the test by M. Sherry Ku et al., they used lactose spiked with 25 ppm formaldehyde (HCHO) (a known cross-linking agent) to compare with the capsules in Cross-linking susceptibility. After storing for 1 week under room temperature, there was no change in the dissolution of hypromellose shell, while the dissolution of the gelatin capsule shell slows down significantly.
