This research work aimed to develop an innovative sunscreen formulation based on Pickering emulsions concept, surfactant-free emulsions stabilized by physical UV filters associated natural oils. The spent coffee oil was used to prepare a w/o sunscreen involving a cold emulsification process, with TiO2, and ZnO as stabilizers and UV filters. The Pickering emulsion was characterized in terms of in vitro and in vivo biological properties of the final formulation, including safety (HRIPT) and sunscreen water resistance tests, using a non-invasive alternative in vivo method. Spent coffee oil presented promising characteristics in the improvement of water performance with a broad spectrum sun protection. The Pickering emulsion was sale for skin application. Concerning the in vivo water resistance study, Pickering emulsion revealed 80.0±3.6% of whiteness, thus supporting the "water resistant" daim and demonstrating that Pickering emulsions are effective at improving water resistance. A novel sunscreen formulation with a high tolerability was developed based on the Pickering emulsions concept. All results revealed an excellent compromise between UV protection, efficacy, safety and cosmeticity.
