Light and non-greasy, this Octinoxate- and Oxybenzone-free anti-sand sunscreen gel applies to wet skin without a whitening effect. SolaStay® S1 provides very rapid and efficient excited state quenching of Avobenzone, protecting it from photo-degradation and improving sunscreen performance. HallBrite® BHB provides sunscreen solvency and emolliency. In vivo testing in a US laboratory (5 subjects) yielded static SPF 64, with 80-minute water resistant SPF 62. In vitro PFA (PPD) ~23 performance with critical wavelength = 379 nm and over four hours of water resistance.
