This water-in-oil sunscreen delivers SPF 100 performance without using organic UV filters. It contains HallBrite® EZ-FLO TDX Plus, which contains two key ingredients for maximum photoprotection formulation impact:
- SolaStay® S1 (Ethylhexyl Methoxycrylene) mitigates the photocatalytic and reactive oxygen species-generating activities of the oxide
- HallBrite® BHB (Butyloctyl Salicylate) aids wetting and dispersion of the titanium dioxide and contributes to enhanced product feel
This formula was subjected to in vitro analysis and delivered SPF ~107, PFA (PPD) ~27, performance with critical wavelength 377nm.
