Water-in-Oil Mineral Sunscreen Cream SPF 40

SolaStay® S1 is incorporated to mitigate the photocatalytic and reactive oxygen species generating activities of oxides, protecting from photodegradation, and so improving sunscreen performance. HallBrite® BHB aids wetting and dispersion of oxides and enhances product feel. This broad-spectrum mineral sunscreen cream was subjected to in vitro analysis and delivered SPF ~42, PFA (PPD) ~18 performance with critical wavelength 378 nm.
