This sprayable formula is suitable for beachwear or any outdoor activity and provides superior broad-spectrum protection against both the burning and aging rays of the sun. SolaStay® S1, an extremely rapid singlet state quenching photostabilizer, and triple state quenching HallBrite® PSF and Polycrylene® help keep the formulation from losing effectiveness during sun exposure. In vitro testing suggests SPF ~35 and PFA (PPD) ~15 performance. Critical wavelength = 377 nm. One person in vivo testing yielded static SPF 39.6 in support of in vitro results.
