- The molecular weight of HPMC significantly affects its gelling properties. Generally, higher molecular weight HPMC results in a higher gelation temperature, as the longer polymer chains require more energy to entangle and form a gel network. Conversely, lower molecular weight HPMC leads to a lower gelation temperature, as the shorter chains can easily entangle and form a gel at a lower temperature.
- The thickening mechanism of HEC primarily occurs due to its ability to hydrate in aqueous solutions. When HEC is introduced into water, the hydroxyethyl groups interact with water molecules through hydrogen bonding. This hydration process causes the linear HEC chains to swell and entangle, leading to an increase in solution viscosity. The extent of thickening depends on the degree of substitution of hydroxyethyl groups on the cellulose backbone, with higher substitution levels generally resulting in greater viscosity.
- After spray-drying, the polymer particles are often coated with a protective layer to enhance their stability and redispersibility
- Pharmaceutical applications of HPMC thickener include the formulation of tablets and capsules
