RP-18 chromatographic-based study of the blood—brain barrier permeability of selected sunscreens and preservatives

Chemical ultraviolet (UV) filters and preservatives used currently in sunscreen preparations are compounds of diverse structures, and the safety of their application depends on their inability to penetrate the skin and other barriers present in the human body. However, at least some of these chemicals meet the general requirements of the good blood—brain barrier (BBB) permeability described in the literature sources. The objective of this study...
