After looking at many different recipes, I chose to sort of "feel my way through" and make a few modifications. The original recipe I used as my guideline is HERE.
Below you'll find my step by step instructions along with a few photos.
1. Finely grate a bar of your favorite soap. I used Kirk's Castile Soap, and I actually used my food processor to grate it until it was almost like powder. Place the grated soap in your blender.
2. Add 1 cup of boiling water to the blender and use a medium-high setting for a few minutes until all the soap is dissolved.
3. Add 1 tsp. glycerin (and optionally, you can add 1 TBSP of honey...I did not do this). Blend again. Then let set in the blender for about 15-20 minutes.
4. Add water to the 6 cup mark on your blender. Blend well again. *At this point, the recipe says to pour into storage containers. For whatever reason, my soap was a really thick gel at this point...so I poured it into a really large mixing bowl (not sure of the size but it's at least a gallon) and added water to get it to the consistency I felt was good for a liquid hand soap. I then used a stick blender to get it thoroughly mixed. If you don't have a stick blender, you can easily just mix it with your hands. You can tell by the photo below that this recipe made enough to fill this BIG bowl.
- Kirk's Castile Soap - $0.69 (Yes, I could have used a much cheaper bar of soap, but this is what I wanted to use.)
- Glycerin - the entire bottle cost $1.87. I used just 1 teaspoon so actually, it probably costs under $0.10.
Basically, more than a gallon of liquid hand soap cost $0.79...and if I had chosen a different soap, could've cost even less than that. Just because something is *cheap* doesn't necessarily make it a bargain if it doesn't work well. This, however, is cheap AND it works great! :) Now THAT is frugality. :)
