In a pilot study to determine if zinc (Zn) from zinc oxide nanoparticles in sunscreen can penetrate human skin in vivo, nanoparticles (~30nm) of a stable isotope (52% 68Zn enrichment) were incorporated into an essentially phytochemical-based formulation and applied to the backs of 3 human subjects twice daily for 5days during the Southern Hemisphere winter. Blood and urine were collected prior to application and at regular intervals and up to 50days. As observed in a larger outdoor trial...[Show more]
