Objective: The aim of this study was to determine the in vitro SPF values along with PH and rheological assessment of five selected sunscreen formulation having labeled SPF, used in east vidharbha region. Methods: The Sun Protection Factor (SPF) is a very popular factor in assessment of sunscreens product. Unfortunately, there is no proper data available on the study of those cosmetic products mainly on SPF. In fact, among much kind of sun screen products used daily in east vidharbha area, only on a few numbers the SPF is labeled. Five different marketed sunscreen formulation having labeled SPF values in range of 15 to 30 were selected, named as F1 to F5 and assessed for in vitro SPF, pH and rheological analysis. It can be observed that the SPF values found for all F1 to F5 are not in close agreement with the labeled SPF. Results and discussion: Formulation F1, F2, F3 and F5 have found more than 80% while F4 have found 73.33%   when compared with labeled SPF. Rheological profiles indicated that the all sunscreens formulation have pseudo plastic properties and exhibited pH in the  range 6.2 to 7.9  Also during collection of sunscreen products it has been observed that, peoples are less aware  about protective spectrum of sunscreens, their correct method of application in vidharbha region. Conclusion: study we want to suggest the attention of the scientific community for and also legal authorities that should control the sunscreens industry in order to supervise and prevent this kind of in corrections, maybe creating legal limits for SPF labeled and the correct amount to apply.
