Welcome, Carrie- I do hope you decide to stay so that we can get your liquid soap-making endeavors started out on a much better footing than the Wiki recipe. If you ask me, the others are correct- that Wiki recipe leaves much to be desired. I would just treat it as a bad memory that's best forgotten, and then start anew.......
Also- from here on out, I hope everyone can treat the rest of this thread in the same manner as the Wiki recipe. Things got off on a bad foot due to stress, misunderstandings, and frayed nerves, but lets move on to better footing.
Carrie- you said you'd like to make a Castile body wash. I may be partial, but when it comes to making liquid soap, you really and truly can't go wrong with the 'glycerin method', which is explained thoroughly in the links that several members posted in this thread.
As Obsidian stated in one of her posts from this thread, you can make a 100% Castile liquid soap with the glycerin method. It sounds like you may have mistook the glycerin method as being a method for making glycerin bar soaps, which is understandable, but that is actually far from the case. The reason why we call this particular method of liquid soap-making the 'glycerin method' is because liquid vegetable glycerin is used in place of some of the water amount.
In case you are leery of using glycerin to make your liquid soap, you need to be aware that one of the natural by-products from making soap with lye is actually glycerin. The percentage of natural glycerin present in lye-based soaps generally runs somewhere between 10% and 15% or so, depending, so using extra glycerin to make lye-based liquid soap is really non-issue and nothing to be leery of......and the extra glycerin makes liquid soap-making so much easier (and much quicker!).
I do hope you'll stay on board and read through the suggested threads. There is a wealth of information there that will save you from so much frustration and that will get you started on the right foot.
