Yes, it's called the brine /salt water soap or Soleseife and you can read over these threads:

I cut it after 1 day and it was nice and firm then, like a normal CP soap. It was over a period of time that it started to crumble. We don't have a humidity issue in N.Cali and I don't think it had anything to do with humidity. I'm surprised to see your soap turned out like a brine/salt bar...
I learned the hard way. I made this soap in 2012. It crumbled like a piece of a cake after 6 months or so. I am curious to know how others are able to make and sell the Dead Sea soap :think: because I only added 2T of Dead Sea salt in my 2 pound batch of soap. By the way, I also made Dead Sea...
Run1251 those soaps came out lovely. Well done :)!
If you added 6 capsules in one pound of MP base, it's definitely not too much, in my opinion. Perhaps the vitamin E did not disperse well with the soap when you first tested it out.
