>>254828For body only alternatives, there's Rhassoul.
It's basically argile, just add water to form a paste, apply it on your skin, leave it for a couple minutes, then remove and rince with a little water, or just leave it like this and it'll go off on its own. It uses very little water, and it'll clean your skin without harming it nor touching its protective layer, which means that it's not that efficient at cleaning, but still it's enough to keep you clean.
On that topic, contrary to popular belief, that protective layer only takes ~30 minutes to be restored, and it doesn't make you immune either, so it's still okay to take showers. But still, when /out/, it could make a difference. It's a nice thing to pack along with Marseille/Alep soap to give your skin some rest, so you can keep actual soap for actual cleaning.
Then there's Manuka honey. Yeah, washing with honey may sound weird, but it works. It's antibacterial, and a great moisturizer. Like Rhassoul, it won't actively 'wash', only keep you clean.
There are a couple more interesting (well, vaguely interesting), but I'll need to check my old notes on soap to find about it. I myself use Alep soap most of the time, and Rhassoul once in a while, especially in very hot countries, I find it more fitting for some reason, and that's really the best solutions you can find, everything else is smalltime in comparison.
