1 bar Castile soap,(I use Dr Bronners.) You should be able to find castile soap in a health food store, Trader Joes)
8 cups of water
3 T glycerin (found in drug store)
Fragrance or essential oils of your choice, 12 drops or as much scent as you like.
Begin by grating your bar of castile soap. You can do this by hand with a cheese grater or if you have a food processor that will grate you can use this and it will go much quicker. Put your grated soap into a sauce pan and cover with water. Simmer until the soap has melted. Add glycerin and essential oils, (I use lavendar & a few drops of tea tree oil for antibacterial). Let this mixture sit for about 8 hours. Then pour into hand soap containers.
