Cool link Zany. I love reading about the different fatty acids in soaps. I would love to one day somehow separate out JUST the different types of fatty acids, like linolenic acid (in triglyceride form of course) and make soap from that to see how it comes out, I know it would not be good, but it would be fun!!!
My favorite is soap high in linoleic. I do have to watch my numbers thou as too much can bring on DOS. But man oh man does it feel good on my skin. My favorite is simple sunflower oil, not the high oleic one.
