This formulation yields a broad spectrum (SPF/PFA ≤3) sunscreen lotion. SolaStay® S1 is incorporated to mitigate the photocatalytic and reactive oxygen species generating activities of Titanium Dioxide and to rapidly and efficiently quench the excited states of Avobenzone. HallBrite® BHB aids wetting and dispersion of the Titanium Dioxide. Olivem® liquid crystal making emulsifiers provide a stable emulsion while imparting sensorial and physiological benefits. This product was subjected to in vitro analysis and delivered SPF ~50, PFA (PPD) ~17 performance with critical wavelength 378 nm.
