These curves have been measured
different times and results have been always confirmed. In the case
of Transpore, a chemical reaction between sunscreen and the
substrate could be the cause of this result.
Some measurements have been performed also on Transpore
self-standing. As already mentioned, the application of the cream
on this substrate is hard to perform due to the fragility of the tape.
Results show that, in comparison with Transpore on quartz, the
shape of the curves was maintained, but the values of transmit-
