Aroma Foundry’s Complete Guide to Making Your Signature Essential Oil Blend

All essential oils offer wonderful benefits to our well being, each with their own unique characteristics. They work completely well when used individually. Most essential oil users surely keep a list of their favorite oils. They value oils for their characteristic scents, therapeutic qualities, and other helpful qualities.

Yet, essential oils are also great when blended together. This is, of course, if you have a good grasp of how to mix and match them. You can create a countless number of blends with the right know-how and tools. Not only does it bring out the creativity in you, blending them also makes notable differences to how oils affect us.

The features that different essential oils hold are often complementary and supplementary to each other. Blending one type of essential oil can tone down the potentially negative aspects of the other. At the same time, they can further bring out the good qualities they possess.

Unlike food or clothing, it may be difficult for us to picture how essential oils could work when mixed together. Blending them requires imagination and a rather skillful nose. Creating fragrances is both an art and a science truly worth discovering.

We guarantee that it will be a fascinating new skill you would soon be flaunting to your friends.

We did a side-by-side comparison with two of the world's biggest essential oil brands.

How To Choose The Best Essential Oils For Your Blends (3 Important Facts)

Before we pop open those glass jars full of oil, there are some very important things we have to understand first. Blending essential oils may seem as easy as mixing a drop of this and a drop of that. However, there are some fundamental factors to consider.

The quality of your blends would depend on how well you choose your oils, and, of course, it must fill the purpose you wish to achieve. You must pay attention to the qualities that different types of oils offer.

Essential Oils According To Scent Type

We will start off by learning how essential oils can be categorized according to their type of scent. Many oils share certain qualities that induce distinct effects on our senses. This can be mainly attributed to the common nature of the oils’ sources.

You may find more diverse sets of categories in other references, but for beginners, here is a list that you can follow. We have also enumerated some essential oils under each category:

Flowery: Lavender, Ylang Ylang, Geranium, Jasmine, Palmarosa, Rose, and Vanilla

Woodsy: Cedarwood, Fir, Patchouli, Sandalwood, Vetiver, Myrrh, Juniper, Coriander, Cypress, Frankincense, and Helichrysum

Citrus: Bergamot, Citronella, Grapefruit, Lemon, Lime, Mandarin, Melissa, Neroli, Orange, and Tangerine

Herbal: Basil, Sage, Eucalyptus, Peppermint, Tea Tree, Sage, Rosemary, Chamomile, Oregano, Pine, Marjoram and Thyme

Spicy: Cinnamon, Clove, Ginger, Nutmeg, and Pepper

Breaking it down into categories and combinations makes it easier for us to narrow down our choices. Naturally, essential oils of the same scent type blend well with each other. This means you can mix any type of oil under the same category without worrying about the resulting aroma. However, it is also important for us to know which types of scent can work well together.

Here is a general guide for us to determine which categories can be blended together:

With Floral scents: Woodsy scents, Spicy scents, and Citrus scents

With Woodsy scents: Floral scents, Herbal scents, Spicy Scents, and Citrus scents

Forest Scents

With Herbal scents: Woodsy scents

With Spicy scents: Floral scents, Woodsy scents, and Citrus scents

With Citrus scents: Floral scents, Woodsy scents, and Spicy scents

Essential Oils According to their Effects

So now you have a good idea of how essential oils can go together according to their scent types. However, remember that aroma is only one of the factors to consider in creating your own signature blends. Essential oils have a lot of other things to offer particularly in terms of health benefits.

You can best utilize essential oil blends if you know how to formulate them to perform certain functions. There are quite a number of situations wherein a good whiff of essential oils can make a positive difference to our well-being.

Do you feel like you lack the energy to stay up and study for your exams? Or did you happen to drink too much coffee and just couldn’t put yourself to sleep? Is a runny nose bothering you while you're doing some chores? Do you feel anxious or tired? Then essential oil blends can surely help. All you need is to know the right oils to combine.

To make it a bit simpler, let us divide our oils into several categories according to their most notable traits. This way, we can lay down our options accordingly based on the purpose of your blend. After that, we can determine the ideal combinations just as we did with the scent type categories.

Essential oils with calming effect:

Lavender, Mandarin, Bergamot, Ylang Ylang, Patchouli, Cedarwood, Geranium, Neroli, Jasmine, Melissa, Palmarosa, Petitgrain, and Sandalwood

Essential oils with invigorating effect:

Sage, Lemongrass, Rosemary, Bergamot, Eucalyptus, Peppermint, Spearmint, Tea Tree, Lemon, Grapefruit, Citronella, Basil, Pine, Cypress, and Ginger

Essential oils with stress-relieving and anxiety-relieving effects:

Essential oils with cleansing effect:

Lemon, Mandarin, Grapefruit, Lime, Citronella, Patchouli, Fir, Peppermint, Rosemary, Tangerine, Laurel, Juniper, Hyssop, and Helichrysum

These categories are only suggestions. Feel free to explore your own combinations. Even better, try doing your own research about the benefits of your essential oils.

Essential Oils According To Notes

‘Notes’ doesn't seem likely as a word to describe oils, but it actually refers to another important aspect that needs to be considered in blending them.

How long or short a scent stays in the air can be similar to how musical notes work in a song. Some essential oils have instantly strong aromas but would immediately disappear after a few huffs. Although, there are some oils that give off a more consistent steady aroma that could linger in your room for hours. This mainly depends on the chemical properties of each type of essential oil. Liquids, including oils, have different evaporation rates. This pertains to how much and how long it changes from liquid form to gas. Creating essential oil blends involves a good deal of science too!

All essential oils can be categorized into three different perfumery notes: Top notes, Middle notes, and Base notes. One of the keys to a successful blend is hitting the right combinations of the three.

Essential oils that are Top notes have powerful scents that you can instantly smell. However, they will evaporate rather quickly and the smell does not last very long. These are good in giving your blend an initial impact and allowing people to feel the immediate difference that your blend will do to the room.

Middle note oils last noticeably longer than Top notes but not as long as Base notes. They serve as the balancing component for the other two. Among the three notes, there are basically more oils under the Middle tone category, so there is a good selection for you to choose from.

The last category is the Base notes. These essential oils produce aromas that stay the longest among all the notes. They often have deep steady scents that are slightly subtler.

Here is a reference you can use to determine the note type of your essential oils:

Top Notes:

Eucalyptus, Basil, Bergamot, Citronella, Grapefruit, Lavender, Lemon, Lemongrass, Lime, Mandarin, Peppermint, Spearmint, Tangerine, and Orange

Middle Notes:

Sage, Rosemary, Tea Tree, Ylang Ylang, Fir, Carrot Seed, Chamomile, Cypress, Dill, Fennel, Geranium, Jasmine, Marjoram, Neroli, Palmarosa, Rose, Rosewood, Spruce, and Thyme

Base Notes:

Cedarwood, Patchouli, Angelica Root, Basalm, Frankincense, Ginger, Helichrysum, Myrrh, Sandalwood, Vanilla, and Vetiver

Based on the perfumery notes, you can now determine the best combinations for your blend -- but no mixing yet! First, you have to know the best way to proportion them.

A reliable guide for beginners to follow is what is now called the ‘30-50-20 Rule.’ This simply means proportioning your blend to 30% Top Note, 50% Middle Note, and 20% Base Note.

You can use as many types of oil to fill each proportion. However, to avoid being too ambitious and potentially waste your oils, you can start off with five.

For example:

Top Note (30%): 1 Type of Essential Oil

Middle Note (50%): 2 Types of Essential Oil

Base Note (20%): 1 Type of Essential Oil

Total of 5 Types

You can always do more complex blends once you have gotten the hang of it.

To Make Your Oil Blends

It is always recommended to start with small amounts when making new essential oil blends. This makes it easier to adjust your proportions and avoids wasting of your oils. Photo source: Pixabay

 This is it! Time to roll up those sleeves and begin mixing your essential oils.

Prepare Your Tools

To begin, you will need a number of tools:

  1. Perfume Strips
  2. Diffuser
  3. A dark-colored glass container
  4. A stirrer
  5. A handy notebook and pen
  6. A cup of freshly brewed coffee. (That's right.)

Choose Your Oils

By now, you probably already have a number of essential oils in mind that you would like to use. Start off with five essential oils of your choice. Just remember that you should consider the three important factors that we discussed earlier: the scent type, the desired effects, and the note type.

Remember: you must have several other oils ready other than the five you will choose. There is a considerable chance that you might not like their combination. It is good to be prepared to replace any of them based on your taste.

Create A Perfume Strip Fan

Time to put your nose to work. Put a drop of each essential oil on separate perfume strips. Smell each strip individually at a fair distance from your nose, moving the strip in a circular motion as you do so.

Were you wondering what the coffee was for? After smelling each scent, take a good huff from your coffee to clear off your senses. Use it as a sort of "rinsing" aid for your nose, a way of cleansing your palate.

After getting a good sniff from each type of essence, hold the strips together in your hand, forming a fan. Wave the fan in front of your face a get a feel of the combined scents. Try to see if a particular scent is overpowering the rest or if there is a certain scent that does not seem to come out. Adjust the quantities of the oils according to your judgments.

Do not make any adjustments to your fan without doing notes. Remember that the purpose of your fan is to get the right proportion when doing the actual blend.

Start Blending

Based on your notes, you can begin mixing the oils in your dark-colored glass container. It is important to start with small quantities. A total of ten drops would be an ideal amount to start with. That way, you can avoid wasting your oils and make it easier for you to make adjustments if needed.

Once you've finished your blend, take in a final inhale. If you are satisfied by its scent, then you can work your way to increase the scale of your mixture. Just make sure that you follow the proportion.

Let It Fly

Surely, you are more than excited now to share your new found aromatic treat. So switch on the diffuser and let your blend fill your house.

If you are good at holding a poker face, try not telling anyone about the new blend you just diffused into the air. Instead, wait for them to react to the new scent and note down their comments. They may be useful to you when you decide to try new combinations later on.

Spreading your essential oil blend with a diffuser is an effective way of sharing your aromatic creation.

Store Your Blend

Congratulations! You have officially made your own essential oil blend. If your blend is a definite love-at-first-sniff, then we recommend that you mix more of them for your future use.

Keep essential oils and essential oil blends in dark-colored glass containers. Essential oils have very high concentrations and they can eventually eat away plastic containers. The dark color of the container will also protect your oils from the deteriorating effects of sunlight.

Let your essential oil blend sit for a few days and monitor the changes that will happen to its aroma. It is good to figure out how long the aroma will last.

Jot down your observations in your notebook.

And Name It!

Why not? This is your blend. There is a great sense of fulfillment if you name something that you yourself created.

Label the containers of your blends. Add the name, the formula you used and the date you made it. You can even color-code them if you like.


Knowing how to blend your essential oils is surely a terrific thing. However, it’s sometimes more important to know what not to do rather than what you can do. So make sure that you know the precautions in handling essential oils.

One of the first things is how to conduct a patch test. This involves applying your chosen oil to a small area of your arm before using it anywhere else in your body. See first how your arm would react to the oil. Your skin may not have similar responses to every type of oil. Some may be too strong to you. Some oils may have certain chemical properties that can cause unwanted effects.

Essential oils are not intended for ingestion. Make sure not to mix it with food. Do not keep it together with kitchen ingredients.

We do not recommend essential oils to pregnant women and nursing mothers. Essential oils have not yet been guaranteed by studies to be safe to women during these times.

You should keep your essential oils out of reach of children and you must not apply it to infants.


Accurately describing how scents affect us can often be tricky. There are only a few words in our vocabulary that are exclusively pertaining to scents. But it is one of the best things that make blending essential oils really exciting. There are no strict rules. There are no right or wrong blends. Feel free to explore. You can experiment with new combinations to discover interesting new fragrances. Bring out the creative chemist in you.

Of course, we must know that the goodness of fragrances is very subjective. Not everyone in your house may like a blend that to you seems so heavenly. However, creating different blends is truly something that any essential oil user would love to learn. It is a skill that raises you a notch higher in our shared fondness for these all-natural products.
