Teach Soap

I'm full of questions this week it seems.... I tried my hand at some cupcake soaps this morning. They don't look too bad although I've never been much good at piping! I dressed them up with a sprinkle of gold mica and stuck a little heart (sliced off a column heart imbed mould) into each one. The recipe made heaps of icing, way more than I had 'cakes' to cover so I piped it into other silicon cupcake moulds. My question is, how long does whipped soap last when it's in use? I've never used it. Does it harden up as much as normal soap?
Thanks so much for all your help - I don't know what I'd do without this forum!

Since whipped soap has extra air whipped into it, it's usually softer and melts quicker than a standard bar. It can still be nice to use, it just won't last as long.
