Depends on how much anone you want in your EO. DPG and ethanol mix well and DPG is made to mix with water alcohol or oil so the method works. The tough part is getting the ratio right, Anone is a volatile mone to work with this way and I have only done it with EST.
This post should help some
I talked to April and she is pretty busy mixing. She said my method would work for the private user but its not how Androtics does it. It more complicated and they have technical machinery that they work with.
