- 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.
