(hpmc solution preparation)
A: Slowly sprinkle HPMC powder into cold water while stirring. Heat the mixture to 60-80°C until fully dissolved. Adjust viscosity by varying the polymer concentration.
A: Always disperse HPMC in cold water first before heating. Use high-shear mixing to prevent agglomeration. Ensure gradual powder addition for uniform hydration.
A: 2-5% w/v HPMC is common for coating solutions. Higher concentrations (5-15%) create thicker gels. Adjust based on desired viscosity and application method.
A: HPMC exhibits thermal gelation - viscosity decreases with heating but increases upon cooling. Maintain solution temperature below 50°C after dissolution for stable viscosity.
A: Autoclave at 121°C for 15-20 minutes if thermal stability is required. Alternatively, use sterile filtration for heat-sensitive formulations. Always test viscosity post-sterilization.
