Umeali, here's a recent, long thread about salt bars:
http://www.soapmakingforum.com/showthread.php?t=55002
The main things about these soaps is (1) using a *lot* of coconut oil in your mix - usually between 80-100% of your oil mix; (2) adding a lot of salt at trace (people vary a lot on this, between 30-100% of the weight of oils); and (3) super-fatting at a very high number, the most common is 20%, to counteract the effects of that much coconut oil, which otherwise would be very drying.
A couple of things to remember about them is that they often trace really fast once you add the salt, so you should have everything ready for your pour once you have done that, and that they will harden fast, within 1-4 hours, so have to check them often and cut as soon as it seems they are ready (read the link for that), or they will be crumbly. Finally, although ready to use after a four week cure, these are bars which - more than most - really seem to do better after a much longer cure.
They produce a bar with a really, really nice lather and a great skin feel.
A recipe is hard because it really depends on your own skin/soaping likes, for example I only used 75% CO, and a higher SF, because I have dry skin. I also made three batches at the same time using the same oils, but different amounts of salt in each one (30%, 50%, and 80%) because of the long cure time, I didn't want to make one, wait for 4 months, try another, wait again, etc. I liked the 50% one the best, but others prefer more or less, you will see from the thread.
I would post my recipe, but it is not typical because of my dry skin, and complicated because I add other additives into it (coconut milk, aloe juice, EDTA, sugar solution), and I think you would want something simpler.
