Abstract: Medicament-loaded Pickering emulsion was prepared with alkylation modified TiO2 nanoparticles as stabilizer,cosmetic grade white oil as oil phase and Astragalus polysaccharides aqueous solution as water phase.Characterization of the TiO2 nanoparticles and the medicament-loaded Pickering emulsion were carried out by transmission electron microscope (TEM),contact angle instrument and optical microscope.Results showed the TiO2 nanoparticles display good dispersity,uniform particle size and favorable stabilizing capacity for the emulsions.Results obtained via UV absorbance test,medicament release effect measurement and water rinse experiment indicated that the medicament-loaded Pickering emulsion shows higher sun-screening efficacy,as well as features for controlled medicament release activity according to irradiation time and easy-water rinsing from human skin.

Key words: sunscreen cosmetic additive, Pickering emulsions, TiO2 nanoparticles, wettability
