Vibrant Vanilla!

Most of us instantly recognize the scent of vanilla.

Vanilla Oleoresin from Plant Therapy beside vanilla beans on tableFor me, it brings back treasured memories of watching my mom work her magic in the kitchen.  As a young girl, I felt proud to “help” her measure vanilla extract into the measuring spoon and then add it to the cake batter or cookie dough.  I would spill it, but she still let me try each time.

Have you ever wondered why real vanilla beans and vanilla extract are SO expensive?  Growing, harvesting, and processing true vanilla beans is time-consuming, painstaking, and still mostly done by hand!

Vanilla beans next to an essential oil bottle filled with diffuser reedsVanilla “beans” (properly called pods) are the fruit of the Vanilla planifolia orchid, and it’s the most commonly grown variety of vanilla. The orchid is native to Mexico and other Central American countries but now grows worldwide. In fact, most of today’s commercial crop comes from Indonesia and Madagascar. [1,2]

Initial attempts to grow vanilla outside of Central America failed completely; Spanish conquistadors who brought the orchids back to Europe failed to recognize that vanilla fruit won’t grow without being pollinated by a certain type of bee!  The method of hand pollinating vanilla was discovered and refined in the mid-1800s, allowing it to be grown in various locales. [2]

Since vanilla flowers only last about 24 hours, the orchids must be inspected each day and hand-pollinated one at a time.  Once the pollinated flower “sets” fruit (a process which takes 5-6 weeks), the pods will mature on the stem for about six months before they are harvested.

Harvesting and curing vanilla pods is even more intensive work than the hand-pollination process.

To avoid producing an inferior product, suppliers hand-pick pods at precisely the right time, just when the bean begins yellowing and the terminal end starts to split.  The curing process begins after harvesting, which involves “killing” the bean (stopping the maturation process) by various methods.  Beans can be dunked in boiling water, frozen, “scratched” down their length, heated in a low oven,  or dried in the sun.  Further curing includes “sweating” the pods, drying them, and then “conditioning” them. The whole process involves at least another six months before the lovely aromatic beans are ready for grading and shipping. [3]

People often ask, “What type of vanilla essential oil should I use/purchase?”

First, technically speaking, there is no such thing as a vanilla essential oil.  The term “essential oil” refers to products obtained during steam distillation or cold pressing of plant material. Since they are not obtained by either process, the term “essential oil” can’t be applied to vanilla products. For aromatherapy purposes, vanilla is obtained either by solvent extraction (Vanilla Absolute or Oleoresin) or by C02 extraction (Vanilla C02).  There are two vanilla products offered by Plant Therapy: Vanilla Oleoresin and Vanilla 12% C02 extraction.

Vanilla Oleoresin       

Vanilla Oleoresin from Plant Therapy on pink backgroundVanilla Oleoresin is a concentrated product made by removing the solvent (usually ethanol) from vanilla extract. Depending on how concentrated the product is, it can be liquid or semi-solid. This explains disagreement in the aromatherapy community as to whether or not to use vanilla oleoresin in diffusers. After owning both a semi-solid and a more liquid oleoresin, I found that frequent use of the thicker oleoresin tended to clog my diffusers. The more liquid oleoresin I currently have from Plant Therapy has not clogged them.  Also, the type of diffuser may have some bearing as to whether or not clogging will occur. For instance, ultrasonic diffusers that use water may clog less, and nebulizing diffusers that spray just a mist of the product might tend to clog more.

As vanilla oleoresin only emulsifies (mixes) fully in ethanol (alcohol), it’s a bit more challenging to work with when making product blends.  As an example, when you put vanilla oleoresin into a carrier oil, the oleoresin will sink to the bottom in a “blob” and remain there. But if you put a bit of oleoresin into alcohol, like vodka, it will dissolve completely.  I did a little experiment and took pictures to illustrate what I mean.

Plant Therapy Vanilla Oleoresin Emulsifies Ethanol and Vodka

In the photo, we see plain Jojoba Oil and vodka in the two beakers.  In the second photo, I placed 3 drops of Vanilla Oleoresin into each beaker. You can see that the oleoresin remains in a “blob” at the bottom of the Jojoba Oil, but the oleoresin emulsifies (mixes) completely in the vodka.  If you want a product where there’s no separation of components (as seen in the jojoba and oleoresin example)  then you’d be better off using vanilla C02 extraction.

Ready for a vanilla DIY?

I make a luscious salt scrub using Vanilla Oleoresin, Coffee Essential Oil, and Orange Sweet Oil–it smells like a caramel latte!  Here’s the recipe:

  • 1/2  cup finely textured sea salt (it doesn’t have to be fancy, though–plain table salt will do.)  I whizz up my salt in the spice grinder to make sure it’s extra fine.
  • 1/4 cup carrier oil.  You can use any oil you wish–olive, sweet almond, etc.–for this recipe I chose jojoba.
  • Coffee and Orange Sweet oils and Vanilla Oleoresin (108 total drops for a 2% dilution–experiment with a few drops of each first to see if you like more of a coffee, vanilla, or orange aroma to stand out.)

Add the oil and oleoresin to the carrier oil and mix. Then, let stand for a few minutes to meld the aromas together. Next, drizzle the oil mix into the sea salt, stirring until you get the consistency you like.  If you like your scrub “runnier, add more oil; if you like it “scoopable” use more salt.  Place into a container with a lid and use within a couple of weeks, as the product has no preservative.

Note: the scrub contains no water, so it technically needs no preserving….but if you’re using it in the tub or shower, it’s going to get wet and will eventually grow mold. For these kinds of products, it’s better to make smaller batches more frequently than to make a larger batch that may spoil before it’s used up. You can also substitute brown sugar for the salt for a luscious sugar scrub.

Vanilla 12% C02

 **Plant Therapy is currently sold out of this product; however, this is valuable information on the CO2 and we will keep this information for the blog**       

Vanilla 12% C02 is obtained by the method of supercritical carbon dioxide (chemical formula: C02) extraction.  Under pressure, C02 gas transforms into an “almost” liquid phase called the supercritical state. Plant material (in this case, vanilla pods/seeds) is placed into an airtight receptacle and carbon dioxide gas is pumped in under pressure; low heat is also applied to aid extraction.

As the pressure inside the container rises, C02 gas nearly liquifies, bathing the plant material in supercritical C02. The combination of high pressure and low temperatures encourages the plant material to releases its aromatic components. After a period of time, there is less pressure and the supercritical C02 changes back to its gaseous state, completely disappearing from the extracted material.

Vanilla 12% C02 extraction emulsifies completely in carrier oil; I love infusing it into jojoba oil for lip balms.  Add 18 drops of vanilla 12% C02 per ounce of Jojoba Oil and mix thoroughly; then you can use the aromatic infused Jojoba Oil as the liquid oil part of your favorite lip balm recipe.

Wondering what the “12%” refers to in the title of the product?

Vanilla flower with vanilla beans on a gray background12% refers to the percentage of the naturally occurring component vanillin, which provides vanilla with its characteristic warm, sweet aroma. There are also C02 extracts containing 26% and 30% vanillin; these are often used in perfumery and are a bit more challenging to work with as they are solid or semi-solid at room temperature.

  1. The last question asks why the C02 is kidsafe but the oleoresin is not – when I go to the oleoresin product in the shop it says that it is kidsafe. Can you please clarify?

    1. Jen, we are so sorry for this confusion! Recently, we reevaluated the chemical constituents in Vanilla Oleoresin and determined that it *does* meet our KidSafe requirements 🙂 This blog was written before the change was made and will need to be updated to reflect this. Please don’t hesitate to reach out to our awesome Customer Service Team at [email protected] for more information

    1. Kel, I would recommend diffusing with an ultrasonic diffuser (uses water), and just be sure you are cleaning after each use so your diffuser doesn’t become clogged. As for being used in or around food, our official stance is:
      “All of our Essential Oils are 100% pure free from any chemicals or pesticides and are ingestible. However, we do not recommend the ingestion of any essential oils. They are highly concentrated and have the capacity to cause serious damage if used internally without the necessary expertise required in administering it. This is supported by the International Federation of Aromatherapists.”

  2. I have actually utilized the fact that the oleoresin does not disperse in oil to make a vanilla infused jojoba oil. I dropped some into my jojoba oil container and left it for a week or two. The jojoba had this absolutely wonderful vanilla scent. It’s Because it won’t dissolve that you can use the oleoresin like vanilla beans to infuse an oil. I’ve also done almond and safflower oil like this. I used it in a lip balm a bit ago which was vanilla infused almond oil, cocoa butter, coconut oil and lime eo. (And beeswax). It worked brilliantly.

  3. When using Vanilla Oleoresin in a recipe just for scent purposes, since it’s not a true essential oil, do you count the drops used for your total dilution?

    1. What are you going to make just for scent? If you’re not making a product that’s going onto the body, dilution isn’t really an issue. But yes, you would count the drops just as you would any other oil.

    1. Are you referring to Vanilla CO2 or the Oleoresin? If you’re referring to the Oleoresin, then no. It would not blend with the carrier oils.

    2. Are you referring to Vanilla CO2 or the Oleoresin? If you’re referring to the Oleoresin, then no, It would not blend with the carrier oils.

  4. So, does this mean that the oleoresin is kid safe to diffuse, just no skin contact? For example, the new Sugar Cookie synergy – can it be safely diffused around a child?

    1. Hi Ann, our “official” position is that it’s better to avoid oleoresin use with children by all methods. We make recommendations, but then it is ultimately up to the customer to decide what’s right for them. 🙂

  5. I’m curious how quickly the C02 vanilla comes out of the bottle. Does it come out quickly, like say lavender EO, or more slowly like vanilla that’s been extracted (not sure if that’s the right word) in jojoba oil? I’ve used the latter from another company and would love something that will mix well with oil but comes out a little more quickly. 🙂

    1. Hi Christy, I’ve heard of two different experiences with the Plant Therapy Vanilla C02. Christina Smith’s vanilla C02 drops fairly readily from the bottle when it’s tipped; and the brand new batch I have is semi-solid in the bottle. Even when the bottle was warmed in my hand it would not drop out, and I needed a small pipette to get it out of the bottle.

    2. My bottle came semi solid and never really “thawed out” so I just put it in a ziplock, use luke WARM water for a couple of minutes to make it loose again. Works like a charm.
