The spray does not require aluminum, what the criterion was why I ordered it. However, this also the schweißverhindernde effect is very limited. Which means you have during the day then spray again to achieve truly 16 hours effect. A 24-hour protection is not possible. The smell is quite strong and sweet. As with all very sweet scents rather it requires a very masculine man to carry him convincingly can, maybe a set older men. All in all, nothing to complain about at the product further.
