This Biphasic Sea Glass Spray SPF 30 has a light and fresh texture and achieves stability without the use of an emulsifier. The combination of Hallstar® Octyl Isononanoate, SolaStay® S1, and HallBrite® BHB helps polarity, viscosity, and density, allowing the formation of two phases. The result is an extra-liquid sunscreen spray that is very easy to apply. Biphasic Sea Glass Spray can also protect hair against the drying effects of the sun. In vivo testing in a US laboratory (5 subjects) yielded static SPF 37. Colipa Guideline (2011) delivered SPF ~34 and PFA (PPD) ~11 performance. Critical wavelength = 375 nm.
