From my experiences, carrier oils will not mix with alcohol. So if you order essentials and you are using alcohol as a base in your fragrance , I would recommend pure essentials. Sometimes they dilute essential oils with jojoba or fractionated coconut oils. Both, I have found , will not mix with alcohol. Maybe there is a way , I'm no expert. But I've wasted some expensive oils trying to mix them with jojoba and alcohol. Hope this helps.
