Because terpenes alone cannot dissolve into a vapable solution, a diluent is needed. At Extract Consultants, we offer 4 different diluents and bases to help you build your product. They are Food-Grade, GRAS and non-GMO. Choose from either our Propylene Glycol (PG), Fractionated Coconut Oil (MCT), Sweet Base, or Sweet Cream Base, to give your products the consistency and taste you want.
