A property of certain materials in which an increased rate of shear favors an increase in viscosity.

In general, viscosity of OsLu was higher than that of Vivinal GOS (Figures 1 and 2); therefore, variations and rheopexy cycles were also higher for OsLu, probably ascribed to the differences in the carbohydrate composition, since OsLu present higher concentration in compounds of DP > 2, as shown in Table 1.
The opposite phenomenon of thixotropy is rheopexy where under a steady shear rate the viscosity goes up before reaching a maximum value.
