Making your own liquid hand soap is easy and cheap! Try this frugal option next time you are about to run out of soap!
First, grate 1 bar of soap. I used Yardley brand (4.25 oz) in Lemon Verbena Scent. You will need ONLY 1 cup of finely grated soap. I didn't use all of the bar, so I just saved the extra in a plastic bag for next time. This cost me about $1.75 at Smith's.
You will also need 1 TBS liquid Glycerin. Glycerin can be found in 1 of 3 places-the suppositories section, behind the pharmacy counter, or in the first aid section (band-aid section). In there was ever any doubt, you do not want to buy Glycerin suppositories! :) This is what it looks like:
This 6 oz. bottle of Glycerin cost me about $3 at Walmart (found it in the first aid section). Since you only need 1 TBS per batch, this will last through approximately 12 batches of soap. That means that it costs about $.25 per batch for the Glycerin.
Lastly, you will need 10 cups of water.
Place all three ingredients in a pot and turn to medium-low heat and begin stirring. Cook until the soap completely melts into the mixture, stirring occasionally. I cooked for probably 3-5 minutes, though it may go faster/slower depending on your soap & stove heat. Turn off the heat and let it cool to room temperature.
I was a little concerned that it was so liquid-y. I read that blending might help, but that seemed weird to me. I did go grab my new turbo frother (yay Ross!), and mixed up the mixture a bit. It bubbled (as soap does). I did this three separate times over the course of the next half hour. It was still liquid-y. I went to go eat dinner with my family, and by the time we were done, the mixture had firmed up significantly. Maybe the frothing (mixing) helped, maybe I just needed to be patient. I then poured some into my empty soap dispensers and put the rest in an empty gallon jug.
For about $2, and with very little effort, I made a little over a half gallon of liquid hand soap (approx. 2 1/2 quarts). That will last a very long time!
