Non-food
2 cups water
3 cups liquid castile soap
Desired scent
3 cups Vegetable glycerin
Measuring cups
Bottle(s) with pump(s)
This is not as thick as store bought hand soap, but it does it's job and allows you to use whatever scent (or no scent) you want.
Mix the water and castle soap in a measuring cup or bowl. Stir in a little of your desired scent at a time until it smells good.
Stir in a small amount of glycerin at a time until desired consistency.
Fill your bottle(s) and put any extra in a jar for later.
*You can omit the glycerin, but the soap will be more likely to dry out your hands.
