The primary function of a sunscreen is to protect the skin using active compounds responsible for the absorption, reflection or scattering of solar ultraviolet radiation. Each solar filter is able to absorb only part of the UV radiation, therefore, to provide broad spectrum sunscreen efficacy, with good photostability, a formulation must contain an appropriate combination of two or more solar filters and a photostabilizer compound. The proposed project involves the efficacy and photostability evaluation of broad spectrum sunscreens containing caffeine. Oil-in-water emulsified systems containing three solar filters - octyl p-methoxycinnamate, avobenzone and titanium dioxide - will be prepared, in order to evaluate the photostabilization potential of caffeine on the filters under study.
