Results show that the test substance was not able to penetrate porcine stratum corneum.
In the experiments with micro fine titanium dioxide formulations T-Lite SF-S and T-Lite SF, mean total recoveries of Ti ranged from 98% to 100% and 86% to 93% of the total Ti applied, respectively. Virtually the total amount of applied Ti could be removed from the skin surface by washing. The amounts of titanium found in the tape strips and skin preparations were in the order of the analytical determination limit. No Ti was found in the receptor fluid at any sampling time. The results show that titanium ions and titanium dioxide particles were not able to penetrate porcine stratum corneum. Therefore, from the absence of internal exposure we conclude that they do not pose a health risk.
