Broad Spectrum SPF 30 Sunscreen Lotion Spray

This 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. SolaStay® S1 also mitigates the photocatalytic and reactive oxygen species generating activities of the oxide to improve sunscreen performance. HallBrite® BHB contributes to UV filter solubility and enhances product feel. This formulation was subjected to in vitro analysis and delivered SPF ~35 (30), PFA (PPD) ~13 performance with critical wavelength 380 nm.
