The aim of the current research work was to develop a stable herbal cosmetic formulation and to study its rheological characteristic and their impact on solar protection factor (SPF). The formulations possess good antioxidant potential and virtuous sensory attributes. An accelerated stability study was performed under variant thermal conditions for 60 days in order to evaluate any variation in droplet size and thixotropy. The droplet size of fresh formulations F1 (WSEA) and F2 (SNEA) was found to be 2.04 ± 0.577 μm and 2.31 ± 0.532 μm with thixotropic value 16964 ± 41 (D/cm2.s) and 16471 ± 35 (D/cm2.s) respectively. The solar protection factor at optimum thixotropic values of both formulations F1 and F2 was 3.11 ± 0.34 and 2.34 ± 0.12 respectively. At accelerated stability conditions, there was a minute reduction in the formulation consistency due to decrease in viscosity and increase in droplet size. The good SPF in these herbal cosmetic formulations was attributed to the presence of polyphenols, which protect the skin from harmful UV radiations.
