Gather a clean 8-ounce bottle or glass container and place a small funnel on top.
Add the fractionated coconut oil, vitamin E oil, and vegetable glycerin to the bottle.
Pour in the liquid castile soap.
Add 15 drops of your favorite essential oils.
If the mixture is too thick, add a splash of distilled water to thin it slightly.
Place the lid on the bottle and swirl gently to combine the ingredients.
Let the mixture sit for a few hours so the ingredients can settle.
Shake before each use, as the oils will naturally separate over time.
