My unfortunate experience trying to light an Optimus 111B stove when it was minus 36 F indicated that the flash point of that batch of fuel was somewhat higher than minus 36, but my experience lighting stoves with white gas is that the flash point is clearly well below zero F, as I could always get the puddle of fuel in the priming cup to light.
I think mineral spirits has a flash point comparable to kerosene, above 100 F.
