Benzoin has been used for thousands of years in many different ways. It's not technically an EO. It's a gum resin that is extracted from deep incisions made in the trunk of the benzoin tree. The thick, gray-yellow sap hardens into a brittle brownish-red resin. The crude resin is then prepared into an absolute or pourable resinoid using solvents like alcohol (which are then removed.) It is widely used in perfumes and pot pourris and also as both a preservative and flavoring in the food industry.
Benzoin Usage in Soap or Candles:
I love benzoin EO in blends. Not only does it help ground blends with its deep, round, rich, vanilla-like scent, but it tends to act as a fixative for more fleeting top notes like citrus oils. If you have an EO blend that just isn't "sticking" or is prone to fading, add a bit (perhaps 10%) of benzoin to the blend. A few blends using benzoin EO:
50% orange
10% litsea cubea
40% benzoin
10% litsea cubea EO
19% orange EO
33% benzoin EO
38% lavender EO
25% orange EO
25% benzoin EO
50% lavender EO
40% lavender
25% orange
10% lime
10% rose geranium
15% benzoin
An old-fashioned French beauty treatment calls for benzoin tincture and rose water to produce a facial wash known as Virgin’s Milk. Reputedly, this formula gives light-skinned women a porcelain-like appearance due to the mixture’s milky coloring. If you’re feeling experimental, the ratio for Virgin’s Milk is a tablespoon benzoin tincture to one ounce of rose water.
