Years ago, WSP had a great MP base which they called something like "Natural Clear". I had resigned myself to not being able to find the same base and having to use bases with SLS or other detergent types in them after WSP discontinued it.
Then I found the MP base or at least a very similar base on Cierra Candles' site. http://www.cierracandles.com/clear-soap-base.html It has great lather, non-drying and easy to melt. It does have a slight yellowish tinge to it but a few drops of blue liquid colorant makes it look clear. The ingredients are "Coconut Oil, Palm Oil, Safflower Oil, Glycerine (kosher, of vegetable origin), Purified Water, Sodium Hydroxide saponifying agent), Sorbitol (moisturizer), Sorbitan oleate (emulsifier), Soy bean protein (conditioner)". It's very reasonably priced (IMO) and they have it set up to minimize shipping cost as much as possible. Here's the link to the page that discusses how they ship soap orders. http://www.cierracandles.com/melt-and-pour-soap.html
