Dilute salt in boiling water or distilled water (I use 3 teaspoons – that way the soap is foamy without blocking the dispensing system).
Fill your dispenser bottle ¾ full of the distilled water. The soap to water ratio Is 1 part soap to 4 parts water.
Add the castile soap. Using good quality castile soap will absolutely affect the quality of the foam
Add the base oil – almond, olive, or vitamin E oil. Choose a good quality base oil that will moisturize your skin.
Add the 10 drops of the essential oil of your choice.
Add the 10 drops of tea tree oil.
Fill the bottle with more distilled water.
Shake the mixture well to combine all the ingredients.
