Is there a simple test I can use?

Hope my reply is not too late
I just experimented with sandalwood oil, obtained from essential oil company. It should be pure, extracted essential oil rather than sandalwood spiked spa (jojoba/coconut) oil.
The sandalwood essential oil 's chemistry is mainly santalol, high molecular weight alcohol/terpene. It contains hydroxyl group which not totally compatible with mineral/petrolium oils. I tried diluting the sandalwood essential oil in mineral oils at 1% and 10% v/v. (didn't try something in between... yet)
At 1%, no problem, clear solution. But at 10%, the solution 's turbid but not separated.
If your oil 's pure, distilled sandalwood essential oil, put less than 1% in your recipe. Or, if you need higher concentration, put some plant based (coconut/almond/jojoba) to improve mixture compatibility.
