Add the lavender essential oil, coconut carrier oil and polysorbate 20 to the plastic spray bottle. These ingredients can easily be found in a craft and hobby supply store. The polysorbate 20, an emulsifier, allows the oil in this recipe to mix with the water, which otherwise won't happen.
Pour the lavender hydrosol into the spray bottle. Floral hydrosols are water infusions taken from the essential oil extraction process. This ingredient can be found in a craft supply store like the others in this recipe.
Secure the cap on the spray bottle and shake it vigorously for about a minute, making sure to thoroughly disperse the ingredients. The end result is a rich, highly fragrant body spray that doesn't contain skin-drying ingredients like alcohol.
