I read on a forum somewhere a few months back that you could make your own liquid hand soap by grating up a bar of soap and boiling it in 6 cups of water. I finally got around to trying it last week. I was concerned when I "Googled" it because I almost always saw glycerin as an essential ingredient in most recipes. If you follow my blog you know I like things uber simple with as few and as "common" ingredients as possible. Glycerin is very cheap and would last a long time though so I'm not knocking it. However, since I didn't have it around, I asked a fellow blogger if it was necessary and discovered that if you use regular bar soap, rather than castille soap, the glycerin is not needed because it already has it.
It worked REALLY well, and was simple enough to make it worth doing again. I was treating it as an experiment, and doubtful that I would do it regularly because of time constraints, but I definitely will continue because it's very easy to do while cooking dinner or any time for that matter. Here's how:
1. Grate bar of soap. (I used Ivory because that's what we typically have around.)
2. Bring 6 cups of water to a boil and add bar soap. Stir until soap is dissolved.
4. Put in dispensers and let sit until it thickens up. With Ivory it turned a whitish color.
Scratch liquid handsoap off my shopping list! Yay!

When I went to make another batch of this I realized that a good bit of soap was still clumped together in the dispensers. I just added a bit of warm water to each one and shook them up and they started shooting out soap again, a bit more liquid, but plenty of soap to do the job!
