Abstract

The sunscreen products contain active ingredients able to absorb, reflect and scatter the UV rays. The in vitro sun production factor (SPF) of some sunscreen emulations marketed in Kurdistan Region can be estimated by ultraviolet-visible spectrophotometer. Fifteen different commercially available samples of sunscreen emulsions of various manufacturers were selected and assessed in vitro SPF values, pH values and rheological profile analysis. The SPF labeled values was in the range of 15 to 100. The values of the 33% of the analyzed samples are in close agreement with labeled SPF, 13% of SPF values above the labeled amount and 54% SPF values under the labeled amount. All samples of sunscreen emulsions exhibited pH values 6.2 to 7.9 and rheological profiles indicated that the all sunscreens have pseudoplastic properties.
