This biphasic sunscreen does not use an emulsifier and yet is stable. The combination of Hallstar Octyl Isononanoate, SolaStay S1, and HallBrite BHB helps optimize polarity,viscosity, and density to form two phases. In vivo testing in a US laboratory (5 subjects) yielded static SPF 37. We used Colipa Guidelines (2011) in our testing which delivered SPF~34 and PFA (PPD) ~11 performance. Critical wavelength = 375 nm. UVA1/UVA – 0.80. Importantly, the formulation contains neither oxybenzone nor octinoxate, which means itcomplies with the 2018 Hawaii sunscreen bill that goes into effect in 2021.
