Have just found some pheros in my glove box of my car. So far, so good, but we have had a strong freeze for some days. The water was becoming to ice and most people have avoided going outside. So my question is: Can pheros killed by freeze?
I doubt that the molecules would be hurt by cold. It’s heat that you normally have to worry about, as it can cause molecules to reach energies at which they can react or break apart, but cold should be fine.
It’s in alcohol, and I believe it has a lower freezing point
SD38 and SD40 are both denatured alcohol if I’m correct. And those have freezing points below 150*F from what I remember.
Either way I think you’ll be fine
I presume you meant below -150°F, P51? Although that would technically still be true. 
SD alcohol has a freezing point of around -173°F, so his pheros should definitely be fine.
Tecically the pheros should be o.k. in my opinion.
What i´m not sure about is that if the low temperatures can cause some kind of fallout in oil products ..
Pago
What do you mean by fallout, Pago? Do you mean a decrease in efficiency? And if so, do you mean permanently, or just for as long as the environment is cooler?
Yes, and oil base products will also freeze. I was also worried cause I got my 2x A314 this week, the temperature here is very low (-about 5F), and I don’t think the DHL van was heated (the package was very cold…). So, I guess the beloved bottles have freezed at some point.
