SolaStay® S1 also mitigates the photocatalytic and reactive oxygen species generating activities of the oxide to improve sunscreen performance. HallBrite® BHB contributes to UV filter solubility and enhanced product feel. This formulation was subjected to in vitro analysis and delivered SPF ~23, PFA (PPD) ~8, performance with critical wavelength 378 nm.
