Essential Oils – Creating Blends and Dilutions

Essential Oils – Creating Blends and Dilutions

There is a huge resurgence of natural health remedies in the U.S. People are starting to really question the use of so many chemicals to “fix” any complaint. Our food is loaded with chemicals. I used to think, if the USDA or the FDA approved the food, it must be good. I don’t think that way anymore. Do we really need all the preservatives and chemicals? It sure doesn’t seem like a healthy way to eat or feed a family. If sickness becomes established in our bodies we trot off to see the doctor who has his handy dandy prescription pad ready with another chemical to counter the ones that made us sick in the first place. I began to question the information the public is given and decided to make a change to a more plant-based and less pharmaceutical lifestyle.

Essential oils and herbs became a solution I wanted to gain in-depth knowledge about. The use of these natural alternatives can be done with some basic knowledge that doesn’t require a mountain of degrees. With that being said, you’ll want to continue expanding your knowledge of essential oils and herbs. You can start out slowly and increase your knowledge over time. You can also consult with professionals who have already learned the best ways to achieve great results.

I was a bit confused about essential oil dilutions and how to blend the oils I felt would help my family’s particular situations. I am sure you might be a bit confused too. There are so many oils and they are good for so many things. So let’s start with dilutions and blends. Dilutions are how you make the oils less concentrated so they are less likely to irritate your skin and help when spreading the oils around your skin. An added bonus, you need less oils and that saves YOU money. Blends are simply mixing oils to create combinations to help a certain concern.

Essential Oils - Creating Blends and Dilutions

Essential Oil Dilutions

Creating blends and dilutions is not as difficult as you might think.  There are many companies that offer essential oils. Investigate the companies and the oils they provide, not all companies offer PURE oils.

The term “CPTG – Certified Pure Therapeutic Grade essential oils” is a trademark of one company that coined the phrase. The words in the phrase, NOT the oils, are registered by the U.S. Patent & Trademark Office. The term has not been awarded to them by the FDA as some think. It does not mean they have the only essential oils that can provide benefits. It is a clever advertising ploy that was bought and paid for. There is a great article by the NAHA organization (National Organization for Holistic Aromatherapy) on this topic.

Do your homework and find essential oils that are competitively priced, not unbelievably low in cost as compared to similar companies. As with many things, cheap is not always better. Make sure you purchase pure, unadulterated essential oils, not fragrance oils. Fragrance oils are artificially manufactured scents and are not able to deliver the benefits that pure plant based essential oils offer.

Dilution Table

Milliliters     Ounces Carrier Oil Drops Essential Oil Percent dilution 
30                = 1 5 – 6 1%
30                = 1 10 – 12 2%
30                = 1 15 – 18 3%

This chart will make it easy to blend the right amount of essential oil to obtain a 1 – 3% dilution in any blend. To further explain, you would use 5 – 6 drops of essential oil in a 30 milliliter bottle, which is 1 ounce, mixed with approximately 30 ml of carrier oil to achieve a 1% dilution. Leave a little space for the blend to breath. This dilution rate is a typical ratio for diluting essential oils. There is no reason to use more oil than necessary. You want to achieve the benefit while making the blend economical. There will be times that a higher dilution rate will be recommended. Using the chart above you will be able to figure out how much will be needed to obtain the higher dilution. Some companies state their oils are suitable for NEAT application. This means they can be applied without dilution. NEVER use essential oils neat unless advised by a clinically trained professional. A patch test is ALWAYS recommended before using the essential oils. The more knowledge you have, the more benefits you can achieve with essential oils.  If you run into a situation where you need to obtain more conversion information, go online and put in whatever you need to convert, such as, ounce to milliliter. You can put in the amount and it will calculate it for you.


There are different reasons for blending essential oils. You can make blends to help with: health related problems to be applied to the skin, aromatically dispersed to freshen a room, used to make cleaning products or beauty products, and for diffusing for various wellness situations. The chart above is intended to be used for blending essential oils you will apply to the skin.

Smells can bring back wonderful memories or times when things may have been unpleasant. The blending of oils for aromatic benefits is usually achieved by using pleasant smells with consideration to the benefits of the oils in mind. Times when the smell is not as important are when specific therapeutic results are desired. In this type of situation, the oil’s benefits can outweigh the smell. Of course, it’s always better if a pleasing smell can be achieved with the therapeutic blend of oils.

How Essential Oils Are Classified

Essential oils have aromas that vary considerably. They fall into three categories called “Notes”. The note signifies the rate at which the essential oil evaporates. The top not being the fastest and the bottom note taking the longest to evaporate. There is a chart showing the category each essential oil falls under by

  1. Top Note – This is the first smell you detect, it makes the first impression of a blend. It dissipates quickly but is considered to be the feature of the oil blend. Generally top notes are from the citrus family.
  2. Middle Note – This is considered the balance or the meat of the blend. This is generally the highest percentage essential oil of the blend. It can be smelled throughout the blend and should be a scent you find pleasing.
  3. Base Note – This is the longest lasting smell in the blend. It “fixes and stabilizes” the blend. Base notes are deep smelling essential oils.

As you start to experience custom blends, start out choosing three essential oils. Select one from each note family. Put a drop of each of your selected oils on a Q-tip or a cotton ball. Wave them in front of your nose and notice which oil you smell first, second and third. Do you find the smell pleasing? If not, eliminate one oil at a time to see which oil is not working for you aromatically. You can change up the oils you selected to find a smell that pleases you. By doing it this way, you will not waste your oils. Once you find a combination that works for you, write down what it is so you will be able to duplicate your blend. You can then increase the drops to make a larger quantity so you will have it ready whenever you want to use your diffuser blend. The suggested percentages to use for each note is 30% top note, 50% middle note and 20% base note. Experiment with this combination until you find the perfect blend for you.

You can use a single oil in your diffuser if you have a smell that you love, or two essential oils. I like the smell of Lemongrass by itself and I like Lavender and Lemon together for a quick blend. You can increase the number of oils as well. Just try to keep a nice balance in your blend. Each person is unique and will find different oils that bring pleasure.


Using essential oils can improve your well-being naturally. It gives a chance to customize blends to improve your health and at the same time make your home smell wonderful. Have some fun with the smells and continue learning other ways to improve your life naturally. If you have questions about the use of essential oils please drop an email: [email protected].

  1. I didn’t realize there was so much to know about blending oils. Very interesting read.

      Thanks for commenting. There is so much to be learned about essential oils. They have a GREAT deal to offer and I just LOVE them. They have helped our family so much. If you don’t want to get very involved with the essential oil world, they can still help you. Read the information on the oils that you want to use. You can dilute them with any vegetable oil (carrier oil) you have on hand. Some of the oils can be used NEAT which means without dilution. Do a patch test as a safety measure. You don’t need but a drop or two to get some amazing results. If you have questions just shoot me an email and I will do my best to give you an answer or get you an answer.

      I studied through Aromahead Institute, here is their information: Aromatherapy Certification Program Online
      The online 235-hour ACP (Aromatherapy Certification Program) allows students to become Certified Aromatherapists, professionally qualified in the therapeutic uses of essential oils. You will have access to Aromahead Institute’s beautiful online classroom, access to exclusive videos, case study assignments, dozens of blending activities, and interactions with other students on Aromahead’s forum.

      Requirements for Aromatherapy Certification
      In order to receive certification from Aromahead Institute, and call themselves Certified Aromatherapists, students must:

      Complete all elements of the Aromatherapy Certification Program (20 case studies, an 8-10 page paper and a final exam).
      Complete Aromahead Institute’s online Anatomy and Physiology class and final exam (included in your ACP tuition at no extra cost).
      Pay tuition in full. If you paid with a payment plan, your payments must be completed to receive your certification.

      The Aromatherapy Certification Program is approved by The National Association for Holistic Aromatherapy (NAHA), and the Alliance of International Aromatherapists (AIA), both leading governing bodies for national educational standards for Aromatherapists. Certification also qualifies you to sit for the Aromatherapy Registration Council exam (ARC).

      I absolutely LOVED the course and learned so much on how to safely and effectively use essential oils.
