There are many ways to do the same thing. Essential oils sprays are an example of that. I share my recipe and a video of another recipe! The bottle to the right is a 2ml bottle. I like to use dark glass bottles to ensure the mixture holds for as long as possible.
The way I make it is using witch hazel, grain alcohol (like Everclear) essential oils and distilled water. The grain alcohol will mix with essential oil and allow it to mix with the water and witch hazel. Essential oils on their own do not mix with water. Witch hazel and grain alcohol will also help to ensure bacterial won't overgrow. (but if you notice a change in the smell or color then it may be rancid)
If you're using a 2ml bottle then 20 drops each of the Everclear, witch hazel and essential oils. Mix these all together then add the distilled water and shake shake shake!
