The calculated degrees of recrystallinity were reported and revealed that %RI was increased with storage time. The magnitude of crystallinity increased in systems stored at temperature in the order of 25 < 4 < 40 8C. Similar trend was found in Q10-loaded NLC dispersions stored for 12 months at the same temperatures (Junyaprasert et al., 2009). The change in %RI correlated well with rheological experiments in which the increased degree of recrystallinity corresponded to the increased system consistencies observed via rheological characterization.
