I tell people that all soap has lye, and that in a properly formulated recipe, all the lye is combined with the oils, so that you're left with a soap molecule and a glycerin molecule. Then I say that, just to be on the safe side and to give my soaps more skin loving qualities, I add more oil than the lye can 'eat', so that even if there is some slight measurement error (I mean we're all human, right?) there is more than enough oil in the soap to make sure that it is skin safe (superfatting for dummies lol). I also tell them that I check the pH and make sure that it is safe for skin prior to sale. Some of my friends are kind of techie geeks and always ask something like, "Really? There's no other way to make soap but to use lye?" And then I explain that, there are indeed plants that produce a saponifying agent, but that it's much more risky that way b/c it's not as chemically controlled and that I've never seen or heard of anyone doing it that way. In fact, I've only seen it mentioned briefly on a few websites and in some books.
I get their concern, though, b/c when I bought my first bar of handmade soap and saw that it said "lye" I cringed and headed right to google before I would use it. :blushes:
