hi, i use jojoba, distilled water, a couple of drops of regular alchol, and f/o or e/o, and oh yes polysorbate 20 as an emulisifer,with sandalwood i use lavender, one of my favorite scents, i do not even mess with it is bergamont and basil, maybe a dash of lime or tangerine in it. i keep mine in the refer so and only make it as i need it, so i do not add a perservative. i love the scent of rose so i use tea rose sometimes, f/o cause the price of the essense would put me in debt for the next 1,000 years
