Sunscreen Lotion SPF 30

This sunscreen lotion formulation was designed to provide broad spectrum (SPF/PFA ≤3) label SPF 30 performance. SolaStay® S1 provides very rapid and efficient excited state quenching of Avobenzone, protecting it from photodegradation, while also mitigating the photocatalytic and reactive oxygen species generating activities of the oxide, improving sunscreen performance. HallBrite® BHB aids UV filter solubility and enhances product feel. This formulation was subjected to in vitro analysis and delivered SPF ~ 37, PFA (PPD) ~ 21 performance with critical wavelength 379 nm.
