Spray recipes with your 10 basic oils
Sprays can be made on a water basis (distilled water or cooled boiled water) with possibly a dash of vodka or hamamelis extract or a pinch of salt or a very small amount of liquid soap - depending on what you want to use the spray for. Then the oils emulsify better with the water.
You can also make oil-based sprays with fractionated coconut oil. Other base oils are often too thick and clog the spray head.
For some applications you can also mix water with a little oil, for example for sprays for the hair. Mixing water with neutral hand & body lotion for sprays is also an option!
Sprays with water should always be shaken well before use, because the essential oil floats on top of the water.
