Light and non-greasy, this Octinoxate- and Oxybenzone-free anti-sand sunscreen gel applies to wet skin without a whitening effect. AvoBrite® provides efficient excited state quenching of Avobenzone, protecting it from photo-degradation and improving sunscreen performance. HallBrite® BHB provides sunscreen solvency and emolliency. Adding Olivem® 2020 in the final phase stabilizes and gives more structure and viscosity to the emulsion and improves its sensoriality. In vitro testing suggests SPF ~55, PFA (PPD) ~17 performance with critical wavelength = 377 nm.
