I don't mean hot water and creating a hot lather, I'm curious about what ambient temperature will do to creams. I locally procured some Proraso and some store brand blades to start off with. I'm about to purchase a sampler pack from WCS and want to include some TOBS. Temperatures have been hitting triple digits recently, is it okay if that shipment gets left in a mailbox or on a doorstep, or will the heat do something dangerous to the cream?
