I've used Ivory, Dove, Neutragena occasionally never had any adverse results.
I can say that one secret ingrediant in shaving soap is clay. I don't know what kind
clay they use but apparently it makes things "more slippy". So I've been told by a soapmaker.
A lot of people I've known over the years use Dove soap as a shave stick. To each their own.
And, in case you're wondering, there are quite a few really good soaps that are vegan.
What happens if you use bath soap instead of shave soap?
wjosephsimmons,
You are my hero! Damn, you sound like a very parsimonious guy. One frugal fellow. I'm too much of a spendthrift. Is this off topic?
