I use either (sunflower, almond, or fract. coconut oil) 1/2 oil, a few drops of Vit E, and the rest FO. When I first started making it following a recipe on here, I used mostly oil not to irritate the skin then slowly I started adding less oil and more FO til I got to half and half in a roller bottle. The scent lasts longer and more positive feedback from clients. HTH
