Homemade Liquid Hand Soap by http://frugalliving.about.com/
-Grate or finely chop a 4 oz bar of soap, such as Ivory or Kirk’s.
-Bring four cups of distilled water to a boil.
-Turn off the heat, and add the soap. Stir to melt the soap. Continue stirring until the mixture is fully combined. At this point the mixture will be very liquidy.
-Allow the mixture to cool for at least 15 minutes. Then, stir again. At this point, the soap should be slightly thicker.
-Allow to cool for another several hours or overnight.
-Stir to check the consistency. If it seems too liquidy, reheat and add more soap. If it seems too thick; reheat and add more water.
-Once you’re satisfied with your soap, add a few drops of essential oil, if desired.
-Then, pour your soap into dispensers, and enjoy.
-Want to make a bigger or smaller batch? Just use one cup of water for every ounce of soap.
-This recipe stores well. Make up a big batch, a few times a year.
-Results will vary depending on the type of soap used. Tweak the recipe until it meets your needs.
-For a super-smooth consistency, run the finished soap through a blender before pouring into dispensers.
