Jojoba oil will not mix with alcohol; that is what you are seeing. As I understand it you are taking your concentrated fragrance and diluting it to 10.0% in Jojoba oil; then taking 30.0% of that and diluting it in 60.0% alcohol. If this is correct I have to ask why? Why not take your concentrated fragrance and dilute it to 10.0% in alcohol, you will stand a better chance of solubility.
"I'm making 10% diluted oil/ alcohol perfume ( 30% oil vs. 60 % alcohol), rest is essentials." I have no idea what you mean by this.
