I saw this on Pinterest and wanted to try my own hand at it. Here's the link to the recipe I found. http://www.thefarmersnest.com/2011/11/liquid-hand-soap-diy.html. I changed it slightly as I had a 4.5 oz bar of soap instead of the 8, so I changed the rest of the recipe to reflect that. Also, being a big fan of the Melaleuca products, I used a Melaleuca bar of soap.
1 bar of soap (I used Melaleuca 4.5 oz pink grapefruit soap)
72 oz water (I used Filtered)
1 1/4 TBSP Liquid Glycerin
First Step: Grate the bar of soap into a clean container. I used a cheese grater to do this.
Second Step: Combine the water, soap and glycerin into a pot and warm (not boil) it on Medium heat until the soap dissolves.
I stirred it occasionally and let it sit until the soap dissolved.
Third Step: Let it sit until cooled. It was suggested to wait 10-12 hours. Mine looked done after about 8.
To think it was made with only 3 ingredients!
