Broad Spectrum SPF 30 Sunscreen Lotion

This sunscreen lotion was designed to provide broad spectrum (SPF/PFA ≤3) performance. SolaStay® S1 is incorporated to rapidly and efficiently quench the excited states of Avobenzone, protecting it from photodegradation and so improving sunscreen performance. HallBrite® BHB contributes to UV filter solubility and enhanced product feel. This formulation was subjected to in vitro analysis and delivered SPF ~32, PFA (PPD) ~14 performance with critical wavelength 378 nm.
