How to Differentiate High Viscosity and Low Viscosity HPMC
1. Physical Property Observation Solution State: High viscosity HPMC solutions are generally more viscous and less fluid. Low viscosity HPMC solutions are thinner and more fluid. Dissolution Rate: Low viscosity HPMC has higher solubility and faster dissolution rates. The solutions are generally transparent. High viscosity HPMC has lower solubility and slower dissolution rates, potentially forming
