Abstract
In the present study, the mechanismof free radical production by light-reflective agents in sunscreens (TiO2, ZnO and ZrO2) was obtained by applying kineticMonte Carlo simulation. The values of the rate constants for each step of the suggested mechanism have been obtained by simulation. The effect of the initial concentration of mineral oxides and uric acid on the rate of uric acid photo-oxidation by irradiation of somesun care agents has been studied. The kinetic Monte Carlo simulation results agree qualitatively with the existing experimental data for the production of free radicals by sun care agents.
