This water-in-oil sunscreen lotion provides broad spectrum sun protection. SolaStay® S1 (Ethylhexyl Methoxycrylene) in HallBrite® EZ-FLO ZDX Plus mitigates the photocatalytic and reactive oxygen species-generating activities of the oxide. HallBrite® BHB (Butyloctyl Salicylate) in HallBrite® EZ-FLO ZDX Plus aids wetting and dispersion of the Titanium Dioxide and contributes to enhanced product feel. In vitro analysis suggests SPF ~ 30 PFA (PPD) ~6, PA ++, performance with critical wavelength 375 nm.
