ultraviolet rays and pheromones

[stuttgart-man]

It is often discussed in the forum that ultraviolet rays destroys pheromones!
Recently there was a report in TV,

why you can not get a sunburn when sitting in car. This is why between you and the sun is the pane. And class do not

let pass the ultraviolet rays emmitted by sun. And as the most products are also packes behind a class, it should

not be worse for the content! Or have I a error in reasoning?

The glass stops a percentage of

the UV. Very few plain or even lightly tinted types of glass do much to stop UV. If they did, your car would stay a

lot cooler during the summer. That's also why sunglasses are UV rated, some better than others, because glass by

itself does not block all the UV. As a matter of fact, it's better at stopping Infrared. You can get a suntan and

possibly a sunburn through glass but it will take longer than otherwise.

Pheromones in dark tinted glass are

much safer than in clear glass but you are better off being safe and keeping them out of the sun as much as

possible.
